Answer:
Detailed descriptions of what happens to the carbon atom:
during photosynthesis (the light-dependent reactions and the light-independent reactions)
transitioning between photosynthesis and respiration
during cellular respiration or fermentation
An explanation of how the carbon atom is transferred between molecules. Please include descriptions of the molecules involved in each of the processes above and be sure to mention the movement of electrons and energy as the carbon atom moves from one reaction to another.
During cellular respiration:
The cell is oxidized.
Transitioning between photosynthesis and respiration:
It is taken from CO2 converted to glucose then either converted back to CO2 or it is used for other processes and may expelled another way.
How is the carbon atom transferred between molecules:
The electrons move through a series of electron carrier proteins, called the electron transport chains, within the thylakoid membrane.For every 12 of the resulting three-carbon molecules made, two are removed to build organic compounds and 10 continue on in the cycle. The two three-carbon molecules that are removed bond together, forming a six-carbon sugar such as glucose.
What happens to the carbon atom during:
Photosynthesis: carbon is taken in from the air, in the form of carbon dioxide and through the energy provided from sunlight it is converted to a carbon chain known as a sugar.

Answer:
i think it b if it not i can look in too it more if you need
Explanation:
The the trend in the data for trial 3 shows that plants grow taller if given more fertilizer, the correct option is b.
What is fertilizer?A fertilizer, also known as a fertilizer, is any natural or synthetic material that is applied to soil or plant tissues to supply plant nutrients.
Fertilizers can be distinguished from liming materials or other non-nutritional soil amendments. There are numerous fertilizer sources, both natural and man-made.
Fertilizers are plant food. Fertilizers replenish the essential minerals lost by crops in the soil. Crop yields and agricultural productivity would be significantly reduced if fertilizers were not used.
It provides nutrients to the plants throughout the growing season. The base fertilizer, along with presowing fertilization and top dressing, forms the fertilizer system used in crop rotation.
The data from Trial 3 show that plants grow taller when given more fertilizer.

Which type of selection will this population of plants most likely experience? directional selection disruptive selection species selection stabilizing selection
Answer: D
Explanation: A population contains short plants and tall plants. The short plants are not able to compete with tall plants for sunlight. The tall plants, however, are more susceptible to wind damage.
Which type of selection are the plants experiencing?
directional selection
disruptive selection
If tall and small plants coexist in a population. Short plants are unable to compete for sunlight with tall plants. However, tall plants are more vulnerable to wind damage, it experiences stabilizing selection, hence option D is correct.
What is stabilizing selection?A form of natural selection when genetic diversity declines as a population stabilizes on a given trait value.
Disruptive selection's opposite is stabilizing selection. It favors the intermediate variants rather than people with extreme traits.
The more severe phenotypes are typically eliminated through stabilizing selection, which leads to the reproductive success of the average or typical phenotypes.
Therefore, stabilizing selection this population of plants most likely experience.

What is a similarity between a tulip and a crocodile? A function of both of their outer coverings is to reduce water loss. In both the tulip and crocodile the male reproductive organ is the testes. The tulip and crocodile both have internal skeletons that support them. The outer coverings of the tulip and crocodile both protect the organism.
Answer:
A function of both of their outer coverings is to reduce water loss
Explanation:
Crocodile and Tulips are both distinct species of organisms. Crocodile belongs to Kingdom Animalia while Tulips belong to Kingdom Plantae. However, despite their elaborate differences, they do have one feature in common, which is the function their outer covering performs.
Tulips are temperate plants I.e. like cold regions, hence, their outer covering functions to prevent excessive loss of water. On the other hand, the scaly skin of the crocodiles help them against water loss. This is common between the two different species.

How would you explain to an athlete why damaged joint ligaments and cartilages are so slow to heal following an injury?
Answer: They have little to no direct blood supply.
Explanation: “Ligaments and cartilage injuries are very common injuries for people who practice sports. Damaged joint ligaments and cartilage are slow to heal because these structures don't have a significant blood supply, which brings necessary fluid and nutrients to the injured place. These nutrients and fluids are essential for damage repairing. If ligaments and cartilage become injured, their limited blood and nerve supply result in a longer recovery and healing period.”
The reason why damaged joint ligaments and cartilages are so slow to heal
is as a result of little blood flow within them.
Cartilages and ligaments are connective tissues which help to connect
bones and other parts together. This part of the body has very little blood
flow and a result blood carrying nutrients aren't adequately supplied to the
region.
Different nutrients and compounds which promote healing and repair of
worn out tissues are found in the blood and failure to reach these regions is
why healing is slow.

blood vessels that contain valves and rely on skeletal muscles to move blood are called:
A) arterioles
B) veins
C) capillaries
D) arteries
and why!? thanks!!
Answer:
veins because they carry low pressured blood due to which there is more chance for backward flow of blood and to prevent that they contain valves.
hope it helped uh..
Answer:
B. Veins
Explanation:
Veins carry blood relying on the action of the skeletal muscle as the body moves. Veins have valves so blood flows in only one direction. Valves are not present in arteries. Arterioles is small and contains valves to prevent backflow of blood but does not rely on skeletal muscles. Capillaries don’t have any valves. The correct answer would be veins.

The curve on the right shows the population five years later. What has happened to this population? (Available answers are in photo) Will mark best answer BRAINLIEST
Explanation:
DIRECTIONAL SELECTION!!!!!!!!!!!!!!!!!!
The population of penguins has gone through the directional selection.
What is directional selection?It is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes.
This causes the allele frequency to shift over time in the direction of that extreme advantageous phenotype.
How these two graphs shows directional selection?On each graph, the X-axis variable is the type of phenotypic trait (here height) and on the y- axis variable is the number of penguins.
Left graph shows the population before directional selection and right graph shows the population after directional selection.
Here height of the penguins reduces and favored over time due to directional selection.
