Summarize the 3 types of cell division: Binary fission, mitosis, and meiosis
Answer:
Binary Fission is the reproduction of prokaryotic cells (bacteria and bacteria-like Archaea) is accomplished through binary fission. Binary fission is essentially cloning. Barring mutations that may have occurred when the genetic material was copied (a process called replication), the two resulting daughter cells are identical to the parent cell.
Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.

What is the function and purpose of the proteins embedded in the cell membrane?
Answer:
The function of the proteins that are embedded in the cell membranes is to transport materials in and out of the cell. Proteins are large sized biomolecules that are also referred to as macromolecules at times. They are made up of large chains of amino acid molecules.

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

9) List these biomes in order from the greatest to least diversity (temperate
deciduous forest, tropical rain forest, temperate rain forest).
Tropical rainforest, temperate deciduous forest, temperate rainforest
I'm not too sure if the temperate forest is more diverse than the rainforest, so sorry if I'm wrong. Tropical rainforests are the most diverse because of the humidity, which is water. The water helps the soil stay healthy, which makes more plants, which makes more animals and insects.
I hope this helps! Good luck!
The biomes in order from the greatest to least diversity will be tropical rainforest, temperate deciduous forest, and temperate rainforest.
Tropical rainforests refer to the rainforests that occur in areas that have no dry season.
The temperate deciduous forest refers to a biome that always changes. It has seasons such as winter, spring, summer, and fall.
Temperate rainforest refers to the broadleaf or coniferous forests that receive heavy rain. This condition supports ferns, shrubs, etc.
It should be noted that the biome with the greatest diversity is tropical rainforest while the least is the temperate rainforest.

Answer:
lithosphere
Explanation:
is up of brittle crust and the top part of upper mantel and also the coolest and most rigid part of the earth
Answer:
Lithosphere:
The lithosphere is the rigid outermost layer of the earth known as the mantle and the crust. And it is defined by its rigid mechanical properties.
Asthenosphere:
This layer is highly viscous and is very mechanically weak and is located below the Lithosphere it is also known as the ductile region of the upper mantle.
Mesosphere:
The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.

A. X-compact; Y-spongy
B. X-spongy; Y-marrow
C. X-spongy; Y-compact
D. X-marrow; Y-spongy
Answer:
it is b X-spongy; Y-marrow, i am doing the test, and the other person is correct.
Explanation:
The arrows point to the bone formations called X-marrow and Y-spongy. So, the correct option is D.
What are Compact and spongy bones?Osteons or haversian systems are tightly packed together to form compact bone. The osteon is made up of concentric circles (lamellae) of matrix surrounding a central canal known as the osteonic (haversian) canal. The bone cells (osteocytes), which are situated between both the rings of matrix, are found in regions known as lacunae.
The bone marrow stores fat and produces blood cells. Spongy bone, also known as cancellous bone, is composed of tiny, needle-like bone fragments organized in a honeycomb pattern. Bones that are more flexible can still be strong while weighing less. In the given example, the arrows indicate to a X-marrow and Y-spongy bone structures.
Therefore, the correct option is D.

What is the difference between glucose and ATP?
Glucose is a storable form of energy, while ATP is a usable form of energy.
ATP is a storable form of energy, while glucose is a usable form of energy.
ATP is only a usable form of energy, but glucose can be used and stored.
Glucose is only a storable form of energy, but ATP can be used and stored.
The main difference between glucose and ATP is that Glucose is a storable form of energy, while ATP is a usable form of energy.
Glucose is storable form of energy because it can't be used as energy until it can be broken down by mitochondria of the cell while on the other hand, ATP is the usable form of energy which we can get from the break down of glucose molecules. Our cells use ATP as a fuel to do various activities of the cell so we can conclude that in glucose, energy is present in stored form whereas ATP is used as energy in various activities.

1-2 Paragraphs About The Background Of Reaction Time Slowing Down Once You Get Older
Answer:
Reaction times slow with age, and they correlate with scores on tests of higher cognitive functions many of which also deteriorate with age. The age-related changes in reaction times account for a substantial proportion of the age-related variance in higher cognitive functions (e.g., Deary, 2000. 2000Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. ... But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.The next time some twenty-something complains that they feel old, you can reassure them that their feelings are, in fact, not ridiculous. After studying 3,305 people ages 16 to 44, researchers found that the brain's response time begins to decline at age 24.
