2. If you break down each of the following, how many different atoms would you be able to recover? a) water
Hydrogen and oxygen atoms are produced when we break water molecule because it is made from these two atoms.
What we gain by breaking water molecules?When we break down water molecules, it splits into oxygen and hydrogen molecules. This can only be done throught the process of electrolysis. By passing an electric current, water can be converted into two atoms i.e. hydrogen and oxygen.
So we can conclude that hydrogen and oxygen atoms are produced when we break water molecule.

Most water is reabsorbed from the filtrate by which region of the nephron?.
The main function of the nephron is to regulate water and other substances within the body where 67% of filtered water is reabsorbed in the proximal convoluted tubule by osmosis.
What is a nephron?It is a complex structure made up of elements such as the loop of Henle, the distal convoluted tubule, the proximal convoluted tubule, and the renal glomerulus.
Through the afferent arterioles, the blood plasma reaches Bowman's capsule, where the glomeruli are located, then the filtered fluid goes up to the proximal convoluted tube for another filtration to take place and part of the water is reabsorbed, the glucose, sodium and amino acids.
Therefore, we can conclude that water reabsorption along the nephron follows solute reabsorption and occurs in the proximal convoluted tubule by osmosis.

what are the differences between plant cell and animal cell
Explanation:
Plant cell:
It is found only in plants.
It consists of cell wall.
Animal cell:
It is found only in animals.
It does not consists of cell wall.
Answer:
The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Chloroplasts
In animal cells, the mitochondria produces the majority of the cells energy from food. Plant cells use sunlight as their energy source; the sunlight must be converted into energy in a process called photosynthesis. Chloroplasts are perform this function. The energy conversion in plants is a complex set of reactions similar to those performed by mitochondria in animals
The Cell Wall
Another structural difference between in plant cells is the presence of a rigid cell wall surrounding the cell membrane. The tough wall gives added stability and protection to the plant cell. If you think about it, most animal cells are inside an organism that has either an exoskeleton or an endoskeleton, built in structure. Plants don't have a skeleton of any kind so the cells have to perform this.
Vacuoles
Vacuoles are large, liquid-filled organelles found only in plant cells. Vacuoles can occupy up to 90% of a cell's volume and have a single membrane. Their main function is as a space-filler in the cell, but they can also fill digestive functions and their interiors can be used as storage for nutrients.
Both plant and animal cells comprise membrane-bound organelles, such as endoplasmic reticulum, mitochondria, the nucleus, Golgi apparatus, peroxisomes, lysosomes. They also have similar membranes, such as cytoskeletal elements and cytosol. The plant cell can also be larger than the animal cell. The normal range of the animal cell varies from about 10 – 30 micrometres and that of plant cell range between 10 – 100 micrometres.
Bees are common pollinators, and many commercially grown crops that we eat depend on bee pollination Bees' eyesight allows them to be such successful pollinators. They have two sets of eyes. At the top of their heads, bees have three smaller eyes (called ocelli) that help them discern light intensity, maintain stability, and navigate. They also have two large compound eyes that detect movement Bees can see ultraviolet (UV) light with their ocelli. Thus, vibrant ultraviolet colors and pattems in flower petals are visible to bees but invisible to us. These pigments often direct the bee to specific parts of the flower (eg, the flower's center). Additionally, their remarkable eyesight allows them to visualize objects at high speeds. For example, while you might see a blur of color if you quickly drove past a meadow, a bee could easily visualize individual flowers in the meadow without reducing its flight speed.
Given this information, consider why these characteristics may have evolved in the bee.In three to five sentences, describe these factors
• how one of these characteristics would benefit the bee .
• how one of these characteristics would benefit the flower or crop
Adaptations such as keen eyesight and ability to visualize colors allows the bees to find food while increasing the plants chances of pollination.
What are adaptations?Adaptation refers to the special features an organism possess that enhances its chances of survival in its environment.
The adaptations in bees such as eye structure help them to easily locate flowers to obtain nectar.
The plants themselves are benefited as they can easily get pollinated by the bees.
Therefore, adaptations such as keen eyesight and ability to visualize colors allows the bees to find food while increasing the plants chances of pollination.

If the 46 chromosomes are duplicated during interphase, why are there
still 46 chromosomes and not 92?
Before I talk about why there are still 46 chromosomes, I'll just review the basic chromosome structure. Each chromosome has a chromatid, with one centromere in the middle.
Chromosomes aren't counted by how many chromatids there are, but rather how many centromeres. When DNA duplicates, the chromatids replicate themselves, so each chromosome ends up having two sister chromatids joined at the same centromere.
There is the same number of centromeres in the cell, so there are still technically 46 chromosomes. However, there are 92 chromatids.

When would your cells be most likely to use fermentation instead of aerobic respiration?.
When you are exercising.
In everyday life when you aren't doing physical activity, you get enough oxygen to move. However, when you are exercising, you're using more oxygen than how much you're taking in. When the body doesn't have enough oxygen, (when you are exercising) it switches to anaerobic respiration (or fermentation).
Hope this helps!
During exercise, the cells of the body demand more energy so they use fermentation instead of aerobic respiration and lactic acid is produced from glucose.
What is fermentation?It is the process of partial oxidation of glucose, carried out by muscle cells when they run out of oxygen to breathe.
This process generates ATP but produces lactic acid as a by-product, which, when accumulated, produces the painful sensation of muscle fatigue during exercise.
Therefore, we can conclude that during exercise, the cells of the body demand more energy so they use fermentation instead of aerobic respiration and lactic acid is produced from glucose.

We can confirm that Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar group are termed vestigial.
What are vestigial features?These can be thought of as features that belonged to ancestors of a specific species and are no longer needed, and thus have been reduced to functionless vestiges through many generations of evolution. The appendix is one such example in humans.

The answer is D) fruits and vegetables that do not spoil easily
You can eliminate B and C, since those two are clearly not positive outcomes (I doubt anybody would want more viruses and fewer animals on Earth!)
A is a little less obvious; however, genetically manipulating crops to have a slower growth rate would be a negative effect on the harvest (and it's probably something most farmers wouldn't want to do anyway.)
So, the answer is D. This makes sense, since having fruits and veggies that don't spoil easily would be a benefit so they can have longer shelf lives.
