Answer:
2. Sediments in the outwash are sorted
The difference between sediments deposited in outwash and sediments deposited in moraines is that-Sediments in the outwash are sorted. Therefore, the correct option is 2.
What is the sediment of outwash and moraines?Outwash is the sediment that is carried away from a glacier by meltwater and deposited in streams and rivers. This sediment is typically well-sorted, which means that particles are relatively uniform in size, shape, and composition.
Moraines are piles of unsorted sediment that are left behind by a glacier as it retreats. This sediment is typically a mix of different particle sizes, shapes, and compositions.
The glacier's movement is not strong enough to sort the sediment of moraines, so it remains unsorted. Therefore, the correct option is 2.

An antibody molecule has a molecular weight of 150 kD when analyzed by SDS polyacrylamide-gel electrophoresis (SDS-PAGE). Treatment with mercaptoethanol, a reducing agent that breaks disulfide linkages, yields polypeptides with molecular weights of 50 kD and 25 kD, and both of these bands are similar in intensity and thickness. Based on this gel pattern as described, what can we conclude about the molecular composition of the antibody molecule
Answer:
The antibody has a molecular weight of 150 kD and consists of four subunits: two subunits of 50 kD and two subunits of 25 kD, which are bonded by covalent bonds.
Explanation:
Sodium dodecyl sulfate (SDS) is a detergent used to alter and denature proteins before gel electrophoresis. SDS can break hydrophobic interactions and hydrogen (H) bonds, but this detergent does not break down disulfide bonds, which is a type of covalent bond between two sulfur atoms. Moreover, mercaptoethanol is a reducing agent used to break disulfide bonds. In this case, it is expected that mercaptoethanol can break disulfide bonds between the four subunits of the mature antibody, thereby yielding two bands corresponding to the 50 kD and 25 kD bands (two subunits of 50 kD + two subunits of 25 kD = 150 kD).

Blood pH is sensed by cells known as chemoreceptors that send information about blood pH to the brain via cranial nerve 9 and 10. In order to correct changes in pH, the ventral respiratory group sends signals to the diaphragm to adjust its rate of contraction. These signals are sent via the phrenic nerve. What serves as the effector in this example
Answer:
The correct answer is - The diaphragm.
Explanation:
If there is a response to stimulation if a bodily tissue or organ becomes active and those of the autonomic system involves two neurons, not single neurons like motor pathways of the somatic nervous system.
In this case, the diaphragm is the organ that gets the signal in order to correct or adjust the rate of contraction in response to changes in pH level, Hence, the diaphragm is the organ that is the effector in this case.
Grass (that is healthy) looks green because Group of answer choices it emits green light and absorbs other colors. it reflects green light and absorbs other colors. it absorbs green light and emits other colors. it transmits green light and emits other colors.
Answer:
it reflects green light and absorbs other colors.
Explanation:
The term pigment derives from the Latin pigmentum, which means the substance that produces color.
Pigments provide color to cells and tissues.
In vegetables, we can find different pigments, such as chlorophyll or carotenoids, among others. Plants use these pigments during the photosynthesis process to absorb sunlight and fixate carbon dioxide. Stem, flowers, and other tissue have pigments in their cells that define the organ´s colors.
Pigments are chemical molecules that produce color by the selective absorption of sunlight. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The color expressed is the product of the reflection. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.
The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.
The green color is ordinary in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.

Answer:
The answers are:
carrier proteins → charged amino acid
Carrier proteins are transmembrane proteins for the facilitated diffusion of charged amino acids across plasma membranes.
osmosis → water molecule
A type of passive transport, osmosis is the diffusion of water molecules in and out of cells.
active transport → calcium moves from low concentration to high concentration
This is the movement of substances across membranes against concentration gradient.
simple diffusion → oxygen
Oxygen molecules enter through membrane by simple diffusion from an area of high to low concentration.
exocytosis → proteins from the Golgi apparatus
This process of exocytosis is used by cells to release particles that has been packaged by the golgi bodies.
Explanation: Boom
Carrier Proteins is Charged Amino Acid, Osmosis implies to Water Molecule, Active Transport - Calcium moves from low concentration to high concentration, Simple Diffusion - Oxygen, and Exocytosis - Protein from the Golgi Apparatus.
In assisted diffusion, a type of transport in which charged amino acids or other molecules bind to particular carrier proteins in order to traverse the cell membrane, carrier proteins are involved.
The passage of charged amino acids through the membrane is aided by this mechanism.
Osmosis is the flow of water molecules over a membrane that is selectively permeable, caused by variations in solute concentrations.
The movement of substances against a gradient of concentration, usually from a region of lower concentration to one of greater concentration, is referred to as active transport.
In this instance, calcium ions are actively moved utilising ATP energy from low concentration to high concentration areas.
Simple diffusion is the gradient-driven passive migration of molecules from a region of higher concentration to a region of lower concentration.
Due to their small size and nonpolarity, oxygen molecules can freely diffuse through the cell membrane through simple diffusion.
Exocytosis is the process through which cells discharge big molecules, such proteins, to the exterior of the cell from the Golgi apparatus.
The proteins are contained in vesicles that join the cell membrane and discharge their contents outside of the body.
Thus, charged amino acid transport is facilitated by carrier proteins, water molecules are moved by osmosis, calcium is moved against its concentration gradient by active transport, oxygen is moved along its concentration gradient by simple diffusion, and proteins are released from the Golgi apparatus through exocytosis.

The La Brea Tar Pits in Los Angeles are the site of millions of fossils from the ice age. Woolly mammoths, giant sloths, dragonflies, and other plants and animals from this era have been found in these pits. Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angeles today. But many of the larger mammals—such as woolly mammoths and saber-toothed tigers—are now extinct. Why do you think this is the case? What can scientists learn about Los Angeles' climate history by studying the specimens found in these tar pits?
Answer:
Scientists learn how climatic changes during the ice age affected life in this region by analyzing specimens found in these tar pits
Explanation:
La Brea Tar Pits are a group of tar pits in Los Angeles. Many preserved remains of ancient organisms (i.e., fossils) were extracted from the tar, including, among others, Western horses, prehistoric camels, three-toed tapirs, rodent bones, insects, mollusks, wood, plants, etc. The oldest fossils have been dated to be approximately 38,000 years ago by radiometric techniques. Moreover, the Last Glacial Period was the most recent glacial period within the Quaternary glaciation, which encompassed the period between 115,000 to 10,000 years ago. This period (LGP) encompassed the Last Glacial Maximum (LGM), which occurred about 20,000 years ago. In consequence, many of the fossils found in La Brea Tar Pits evidence how the ice age affected life in this region. Moreover, many of the fossil species extracted from the tar are still present today, thereby indicating how these species adapted to fluctuating climatic conditions, whereas certain species couldn't adapt fast enough as the environment changed and therefore they went extinct.
Answer:
Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angeles today. But many of the larger mammals—such as woolly mammoths and saber-toothed tigers—are now extinct. I believe this is the case because since bigger beasts couldn't take shelter in small protected burrows, perhaps they were done in by fierce environmental conditions. Or maybe with so many plants dying off, big herbivores simply had nothing to eat, and as they died out, so did the big carnivores. By studying the spicemens found in these tar pits scientists can learn about Los Angeles climate change. For instance, new scientific studies at the La Brea Tar Pits are probing the link between climate warming and the evolution of Ice Age predators, attempting to predict how animals will respond to climate change today.

of the red blood cell. Which ion is this, and what
molecule is it a part of inside the red blood cell?
Answer:
a. Iron (Fe) ion
b. Haemoglobin
Explanation:
Red blood cells (RBC), also known as erythrocytes, are one of the cells found in the blood. Red blood cells are the major components of the blood involved with the transport of oxygen throughout the body. Red blood cells are able to do this because they contain proteinous molecules called HAEMOGLOBIN.
Haemoglobin is a molecule that contains hemic iron groups. Haemoglobin is composed of an IRON ION at the core of its structure, which binds to oxygen atom. Hence, according to this question, haemoglobin is a proteinous molecule that contains iron-binding heme groups in the red blood cells.

Answer:
it generates NADH for use in mitochondrial ATP production
The function of Calvin cycle is to generate NADH for use in the mitochondrial ATP production in the process of cellular respiration. Thus, the correct option is A.
What is Calvin cycle?
Calvin cycle is also known as the C3 cycle or citric acid cycle. It is the cycle of chemical reactions where the carbon atom from the carbon cycle is fixed into various different molecules of sugar. It occurs in the chloroplast of the plant cell.
Calvin cycle is an important mechanism as it involves performing chemical reactions by plants to fix carbon from CO₂ into the three-carbon sugars (glyceraldehyde). Afterward, the plants and other creatures can transform these three-carbon compounds into amino acids, nucleotides, and other more complex sugars like starches. Calvin cycle generates NADH for use in the mitochondrial ATP production.
Therefore, the correct option is A.

At the time Hutton proposed his ideas about the age of rocks, how old was Earth believed to be by most people in Scotland?
Answer:
In the late eighteenth century, when Hutton was carefully examining the rocks, it was generally believed that Earth had come into creation only around six thousand years earlier (on October 22, 4004 B.C.
James Hutton was a Scottish naturalist and geologist who discovered the age of the earth. The earth was believed to be 6000 years old by the Scottish people.
Who was James Hutton?
James Hutton is the father of modern geology and was involved in the discovery of the earth's age and the soil formation from the parent rocks. He made his contribution to discovering the age of Earth based on his observation rather than on assumptions.
Before he discovered the earth age, it was believed by the Scottish people that the planet was six thousand years old. He discovered the process of soil formation by weathering the parent and bog rocks that accumulated as sediments over years and allowed the discovery of the planet's age.
Therefore, it is believed that the earth was 6000 years old.

What happens with the release of DDT into the food chain zooplankton -- small animal -- large animal-- bald eagle? And what process is involved
Answer: The process involved is called BIOACCUMULATION.
Explanation:
Dichlorodiphenyltrichloroethane (DDT) is a type of pesticide used in agricultural control of pests. It's use has been restricted because of its involvement in bioaccumulation. The pesticide is known for accumulating in food webs and persisting in soil and river sediments. This leads to it's accumulation (build up) in living organisms.
Pesticides and fertilizers are used in crop cultivation. Rain and irrigation water wash these chemicals, especially the soluble nitrate fertilizers, into the ground water and they eventually get into rivers, lakes and seas.
These pesticides such as DDT are synthetic organic compounds that are non-biodegradable. When they are washed into the ground water, they accumulate in the bodies of plants (zooplankton). These are eaten by small fishes which are in turn consumed by larger fishes. These large fishes are hunted as prey by the bald eagle.
DDT builds up in these bald eagle causing them to lay eggs with thin shells. As a result, the eggs break easily causing a fall in the eagle population.
