pls answer my question!
Beth broke her ankle bone. The doctor gives her a
brochure on foods she can eat to help restore the
health of her bones. Which element will help Beth
strengthen the bone?
Answer:
Calcium
Explanation:
Calcium is the healthy bone mineral. About 99% of the calcium in the body is stored in the bones and teeth. It's the mineral that makes them hard and strong. The remaining 1% is needed for many activities that help keep the body functioning normally.
Answer:
Phosphorus will strengthen her bones.
Explanation:
There are a wide number of dietary minerals that are involved in the strengthening of bones. But among all of them, calcium and phosphorus are the key minerals that play an active role in providing strength to the bones. Phosphorus keeps the bones healthy and strong. It also helps in the growth of bones.
Low amounts of phosphorus can lead to thinning of the bones, a disease termed as osteoporosis.

Use the text to identify the sentences with evidence that matches the claim.
Claim 1 --> Tropical rainforests contain more biodiversity than all other biomes.
1) Biodiversity refers to the total number of different species of all kinds living in an area.
2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.
3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.
4) Surprisingly, rain forest soil is very poor.
5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.
6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.

Which scenario represents a "fit" individual in terms of evolution?
1 point
The individual can run for long time without getting tired.
The individual has many children that survive and reproduce.
The individual has no children and lives a long time.
The individual has one child that does not reproduce.
Summary
The life history of a species is the pattern of survival and reproduction events typical for a member of the species (essentially, its lifecycle).
Life history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction.
One tradeoff is between number of offspring produced and the amount of energy (both physical resources and parental care) put into each offspring.

evolution by natural selection is an example of a scientific
Answer:
Ideas aimed at explaining how organisms change, or evolve, over time date back to Anaximander of Miletus, a Greek philosopher who lived in the 500s B.C.E. Noting that human babies are born helpless, Anaximander speculated that humans must have descended from some other type of creature whose young could survive without any help. He concluded that those ancestors must be fish, since fish hatch from eggs and immediately begin living with no help from their parents. From this reasoning, he proposed that all life began in the sea.

What is mean by photosynthesis?
Answer:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunligh, so we eat the plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the reen pigment found in the chlorookasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Which of the following correctly describes Metaphase?
A. The Cytoplasm splits, forming two daughter cells
B. Centrioles move to opposite sides of the cell, nuclear envelop dissolves, chromosomes form
C. Chromosomes split and move to opposite sides of the cell, the cell elongates
D. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell
Answer:D
Explanation:
. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle.
In the metaphase, mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell. The correct option is D.
What are spindle fiber?Spindle fibers form a protein structure that divides a cell's genetic material. The spindle is required to split the chromosomes in a parental cell evenly into two daughter cells.
During metaphase, these spindle fiber gets attached to centromere of the chromosome and align the chromosome at the equator.
Long protein fibers known as microtubules prolong from the centrioles in all directions, forming a spindle. Some microtubules connect the poles to the chromosomes via protein complexes known as kinetochores.
Spindle fibers from the opposite side of the cell connect to the chromosome's both these sister chromatids.
They connect at the kinetochore, which comprises a disc or protein on each side of the centromere. The chromosomes will be moved by the spindle fibers until they are aligned at the spindle equator.
Thus, the correct option is D.

A cell pumps hormones out into the bloodstream; a process that requires energy. If 4 ATP were converted to ADP, how much energy was used?
A. 4 kJ
B. 30.5 kJ
C. 122 kJ
D. 1600 kJ
It is 122KJ of energy is used from the conversion of ATP to ADP because hydrolyses of 1 mole of ATP requires 30.5KJ of energy. Therefore, if 4 ATP is hydrolyses, it will be 4× 30.5=122KJ. ... This energy is given out because there is cleavage of high energy phosphate bond in ATP while converting it into ADP.

Answer:
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains.
Explanation:
took the test and got it correct
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains. The correct option is D.
What are Eubacteria?Eubacteria are bacterial counterparts. They go under the name "real bacteria." They lack membrane-bound cell organelles and a genuine nucleus. These are single-celled, tiny creatures.
Contrary to appearances, Eubacteria and Archaebacteria (also known as Archaea) are divided into distinct realms of life based on variations in their genetic make-up, particularly in the sequences of their ribosomal RNA (rRNA).
Together with Eukarya, Eubacteria and Archaebacteria are currently acknowledged as distinct domains of life.
This classification represents the underlying biological differences between the two categories, including variations in cell walls, lipid membranes, and metabolic pathways.
Thus, the correct option is D.
