Answer:
There will be a larger sea urchin population and less kelp. Having less kelp will result in habitat loss for other organisms.
Explanation:
The sea otters preyed on the sea urchin, and the sea urchin preyed on the kelp. When the sea otter population whipped, there was no other organism to prey on the sea urchin. This leads to a larger population of sea urchins, and now since this happened, there will be less kelp because the population of sea urchins has increased, and that's what they feed on. With less kelp, there will not be a habitat for other organisms.

Answer:
The answer is B
Explanation:
Think of it this way; Respiration = Breathing and we are on the cellular level
Cellular respiration is the process of releasing energy from food. The correct option is A.
What is cellular respiration?Cellular respiration is the process of breaking down food molecules into simpler forms to produce energy in the presence of oxygen. The oxygen is added to the food to produce energy and release carbon dioxide and waste material out of the body.
Oxygen is taken from the environment, and they are attached to the hemoglobin molecule of the blood and taken into the body, then this oxygen is used in the metabolic function of the body.
Breathing is the process of getting air into the lung and out of the lungs. It is not a part of cellular respiration.
Thus, the correct option is A. The release of energy from food.

what process takes place at the boundary between the capillaries and the alveoli?
Answer:
Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Explanation:
This describes the exchange of gases in the lungs. When blood from the rest of the body gets to the lungs through the capillaries, oxygen flows from the alveoli which are tiny air sacs in the lungs, into the blood in the capillaries.
Carbon dioxide from the blood brought to the lungs will then flow into the alveoli which will then expel it through the nose. This repeated process ensures that the body keeps getting oxygen and expelling carbon dioxide.
Answer:
Exchange of Gas takes place in lungs between the alveoli and capillaries which are tiny blood vessels, placed at the walls of alveoli. The rate of diffusion depends on the thickness of the biological membrane which forms the boundary between the external environment and organisms.

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following correctly describes the result of this mutation?
1.A deletion occurred so all of the amino acids added after the mutation may be wrong.
2.An insertion occurred so all of the amino acids added after the mutation may be wrong.
3.A substitution occurred so all of the amino acids added after the mutation will definitely be wrong.
4.An insertion occurred so all of the amino acids added after the mutation definitely will be different.
Answer:
Explanation:
1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.
2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.
3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.
4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

emily wants to know how green, blue and red color light affects plant growth compared to natural light. (Hint: what light affects the plant the most) Form hypothesis and design an experiment. Make sure identify the control, independent (manipulated) variable and dependent (responding) variable. Be detailed
Red and blue colored lights are most effective for plant growth.
Plant Growth is the dependent variable and light color is the independent variable. The rest are control variables.
A Control variable is the part of the experiment that we keep the same throughout all of the test subjects. An independent variable does not depend on other variables and a dependent variable does.
Allow me to explain. When we perform an experiment, many factors that can change the results, For this reason, it is common practice to keep many of them the same for all test subjects (In this case for all of the plants). This way we know that if changes are measured, they were not caused by these variables. These are what we call control variables.
An independent variable does not depend on other variables to remain the same. For example, the species of plant would be an independent variable, given that a plant cannot change its species because of other factors.
A dependent variable does change according to other variables and is often what we try to measure. For this example given, the dependent variable is how much the plant will grow with each colored light.
Knowing that plants rely on light to produce the energy needed to grow, we can hypothesize that applying different colors of light will have an effect on plant growth. To test this, we can create an experiment where we use:
Soilamount of wateramount of lightspecies of plantlength of experimentAs control variables.
One group of plants will have blue light, another green, and another red. We can identify the color of light as an independent variable.
Since what we seek to measure is plant growth, we identify this as our dependent variable and measure it for each plant after a set amount of time, to compare results.
With this, you can confidently identify the control, dependent, and independent variables and how to use them in your experiment.

Well this isn’t biology this is earth science but it doesn’t have the option.... 1. What geologic processes must have occurred for fossil ammonites (relatives to the nautilus that dominated oceans hundreds of years ago) to now be found in rocks at the highest mountains on Earth??
2. What would our planet look like if it contained no radioactive isotopes within it? What would it look like if radioactivity were producing twice as much heat within Earth’s interior?
The answers are that the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. With no radioactive isotopes, the Earth's geography would be vastly different and void of life. If radioactivity produced twice as much heat the earth would become unstable.
The discovery of fossil ammonites within rocks at the highest mountains on Earth is due to orogenic plate tectonics. Plate tectonics is the name we use to describe a process in which pieces of the earth's crust move and often slam into each other, causing one of these to pile onto the other.
This can lead to the formation of mountains and mountain ranges. This process helps to explain why fossils of ammonites known to dwell in the ocean can be found in mountains.
Radioactive isotopes, or better yet, the decaying of radioactive isotopes, are responsible for generating most of the Earth's internal heat. The internal heat of the earth is the driving force of plate tectonics and without it, much of the geological activities responsible for the earth's current geography would not have happened.
Mountain ranges would not have formedPlate tectonics would not have caused the formation of the continents we know todayThe earth would lack a magnetic field to defend against ionizing radiation from the sunLife would likely not have evolved.Radioactive isotopes were vital in allowing for the conditions of the earth at the time that life evolved, and the heat they produce allows the earth to have a molten core and thus generate a magnetic field for protection.
Now, if the heat produced by radioactive isotopes were to double, the Earth's internal temperature would nearly double. Since this heat is the driving force for plate tectonics, we can expect a sharp increase in the number of earthquakes and volcanic eruptions. These can, in turn, cause tsunamis and changes to the earth's global temperature. Mountains would form continuously and continents may break apart. This instability would make life on earth's surface improbable.
Therefore, the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. Without radioactive isotopes, the Earth's geography would be vastly different and void of life. Radioactivity producing twice as much heat would make the earth very unstable.

Which of the following does NOT secrete hormones?
A. Ovaries
B. Skin
C. Adrenals
D. Pancreas
Answer:
skin acts as a protective barrier, therefore it does not secrete hormones
Skin does not secrete hormones. Thus, the correct option is B.
What are Hormones?Hormones may be defined as chemical substances that are produced by the organ system of an organism and transported at the site of action via the bloodstream. Hormones act as messenger molecules in the body.
Skin acts as the primary or first line of defense for the immune system. It does not secrete any hormones. It plays an important role in innate immunity. Ovaries are responsible for the secretion of hormones like estrogen and progesterone in females and regulate all the prospective consequences in the body of females.
The adrenal gland secretes hormones like cortisol and aldosterone which are steroid hormones. Such hormones are important in regulating metabolism, inflammation, immune functions, etc. The Pancreas secretes insulin and glucagon which play an active role in regulating the level of glucose in the blood.
Therefore, the skin does not secrete hormones. Thus, the correct option is B.
