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.
This used to be confusing for me too :) hope it helps!

What is one difference between renewable and nonrenewable resources?
Provide one example of a renewable energy source, and one example of a nonrenewable energy source.
The difference between these two types of resources is that renewable resources can naturally replenish themselves while nonrenewable resources cannot. This means that nonrenewable resources are limited in supply and cannot be used sustainably.

Paragraph 3 describes the diagram at the top of this article. It demonstrates:
A: that energy flows in one direction beginning with light energy
B: the transportation of sugars into mitochondria
C: the Krebs Cycle
D: the Calvin Cycle
Photosynthesis involves a series of reactions including trapping of sunlight energy and the Calvin cycle through which plants make their food in the form of sugars.
What is metabolism?Metabolism refers to the sum of reactions that occur in a living organism which helps obtain energy and remove waste in order to sustain the life of an organism.
Different metabolic reactions take place in plants and animals.
In plants, energy is obtained from the sun and is used to drive photosynthesis.
The sugars made in photosynthesis are stored in roots, stem and tubers as well as in fruits.
The sugars can be broken down to produce energy in th mitochondria.
The Calvin cycle is the process that plants use to convert carbon dioxide and water to sugars
The Krebs cycle is a cycle which produces molecules which are used to produce energy in the mitochondria.
Therefore, since the diagram is not attached, the process shown can be understood from the explanation of each process in photosynthesis and metabolism.

What factors contribute to uranus experiencing "the most extreme seasons in the solar system"? relate this to how earth experiences seasons. (use cer as a resource, 4-5 sentences.
Uranus have extreme seasons due to its unique tiltation of 82 degrees
Why does Uranus have extreme seasons?The orbit of Uranus is circular which maintains the same distance from the Sun throughout year. But Uranus is tilted about 82 degrees which gives rise to extreme 20-year-long seasons and unusual weather.
So we can conclude that Uranus have extreme seasons due to its unique tiltation.

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.

How might it be possible for a child to show a trait that neither of the parents showed?
A person can only show a recessive trait if both of their parents carried at least one copy of each of the recessive allele. The parents do not need to show the trait, as one copy is not enough to reveal it, but they must both carry it.

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.

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.
