Answer:
Regeneration, Mitosis, and Meiosis.
These 3 processes involve cells dividing to make new daughter cells that repeat the process. However, regeneration only occurs when our systems are damaged and need repair by cells.
Hope this helps!
Answer:
Mitosis
Explanation:
When people say "cell division," they usually mean mitosis, the process of creating new body cells. Meiosis is the cell division process that results in the formation of egg and sperm cells. Mitosis is a necessary part of existence. 26th of March, 2021

if humans were wiped out and allowed room for a new dominant species, out of all animals listed which one would have the most potential to do so?
Answer:
the raven
Explanation:
octopus - intelligent but very antisocial with a short life span, meaning they most likely will not work with other octopuses to improve while also living in the ocean making it harder to build. (but could probably evolve to walk on land)
dolphin - smart but does not have thumbs to make tools and lives in the ocean meaning they have a disadvantage.
raven - intelligent, works with other ravens and sometimes even wolves, and has shown to make tools.
Answer:
The raven because it's ability to craft tools, social life involving hunting groups, intelligence, and wide variety of sounds (allowing potential language) give it the potential to evolve very well.

Explanation:
Beavers, large members of the rodent family in North America, are often referred to as "ecosystem/keystone engineers" by wildlife managers. Ecosystem engineers are described as animals that create, alter, or destroy a habitat. Beavers contribute to river ecosystems by bringing down old and dead trees along riverbanks. They use these trees to make their dams. Although these dams are primarily used for protection and food storage, scientists report that these dams change the surrounding environment in different ways. Given this information, in three to five sentences, describe a potential benefit that beavers contribute to the ecosystem as keystone engineers and describe a plausible impact that the removal of beavers could have on the surrounding ecosystem. (4 points)
The potential benefit that beavers contribute to the ecosystem include sources of food and habitat for some animals.

This consists of all the organisms and the physical environment with which they interact.
The removal of the beavers will allow for more oxygen to be present within the ecosystem as a result of increased plant population.

what molecules link together to form proteins
Answer:
Peptide bonds
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
Do you predict that salt will be able to move across the membrane?
1. Yes, because NaCl is small
2. Yes, because NaCl is ionic
3. No, because NaCl is large
4. No, because NaCl is ionic
Answer: The correct answer is
No, because NaCl is Ionic
Explanation:
NaCl can pass through the cell membrane because it is Ionic and separates into Ionic components Na+ Cl+.
Cell membrane are phospholipids bilayers and have hydrophobic tails and face inside of the cells . The fatty acids tails are non polar and only non polar substances can pass through it but salts is a polar molecules because it is an ion and cannot pass.

A company wants to test a new dog food that is supposed to help overweight dogs lose weight. 50 dogs were chosen to try the new food and 50 other dogs were chosen to continue their normal diets. After one month, the dogs are checked to see if they lost any weight. What is the Dependent Variable?
Answer:
The dependent variable is the weight of the dogs
Explanation:
The dependent variable is the variable that is been tested during the course of an experiment. The dependent variable will usually produce different unpredictable "values" which will form the essence of the experiment. Also, the dependent variable is usually dependent/relies on the independent variable.
From this description, the dependent variable is the weight of the dogs as this is the variable that is been tested.
What molecule do plants pull from the air that is used to make sugar?
A.Oxygen
B.Nitrogen
C.ATP
D.Carbon dioxide
Answer:
carbon dioxide is what the plants take from the air to make glucose or sugar
The molecules that the plants pull from the air that is used to make sugar are carbon dioxide. The correct option is D.
What is carbon dioxide?
Carbon dioxide is a gas that is present in the atmosphere at 0.03 %. This gas is a greenhouse gas. This gas warms the environment. The chemical formula of carbon dioxide is CO₂.
Carbon dioxide is released by animals as they respire. This is the gas they expelled out in respiration. But plants absorb this gas because plants perform photosynthesis and in photosynthesis, carbon dioxide is used.
This gas is pulled from the environment to perform photosynthesis by plants. Carbon dioxide reacts with water to form glucose.
The chemical reaction of photosynthesis
[tex]\rm CO_2 + 6H_2O \rightarrow C_6H_1_2O_6 + 6O_2.[/tex]
Thus, the correct option is D. Carbon dioxide.

name the stimulus, control control center, and the receptor when ABA is released. Please I need answers thanks!
Answer
ABA
Explanation:
It is believed that this mechanism, in situations of hydric stress, is controlled mainly by abscisic acid, a plant hormone known as ABA. This hormone binds to receptors in the membrane of the guard cells and promotes the entry of calcium ions (CA2+), which function as messengers when opening ionic channels. When these channels are opened, the chlorine(Cl-) and malate2- ions pass from the inside of the cell to the wall and open the K+ channels, causing the exit of this ion as well. This process causes the water to come out and the stomach closure occurs. When the ABA is released from the receiver, the ions that came out of the cytoplasm, together with the water, return to the inside of the cell, making it turgid. At this moment, the stomach opens.
Therefore, it is perceived that the ABA causes the stomatum to close, thus guaranteeing water savings. In environments with water stress, this mechanism guarantees the survival of the plant.
In addition to water stress, several factors directly affect the opening and closing of the ostyolus, such as the concentration of carbon dioxide, light, temperature and water loss. It is also worth mentioning that the stomata also open and close at circadian rhythms, that is, according to daily rhythms.

All of the following are found only in plant cells except
a. Large central Vacuoles
c. Cell walls
b. Chlorophyll
d. Chloroplast
Answer:
There is no answer to that.
Explanation:
Chlorophyll is located in the chloroplast, and it is a crucial component in green plants for photosynthesis.Cells walls are present in plant cells only.Large central vacuoles are part of plant cells, too.None of the options are correct.
Vacuoles are also present in both the animal cells and plant cells. Therefore, option (A) is correct.
What is a plant cell?A plant cell is a type of cell that is found in plants. It is similar to an animal cell in many ways, but there are also some important differences. Like animal cells, plant cells have a cell membrane, cytoplasm, and genetic material (DNA) contained in a nucleus. However, plant cells also have some unique features that are specific to plants.
One key feature of plant cells is the presence of a cell wall. The cell wall is a rigid structure that surrounds the cell membrane and provides support and protection for the cell. It is made up of cellulose fibers and other structural proteins.
Plant cells also contain organelles called chloroplasts, which are responsible for photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts contain pigments called chlorophyll, which absorb sunlight and use it to convert carbon dioxide and water into glucose (a sugar) and oxygen.
Plant cells also contain other specialized organelles, such as mitochondria, which are responsible for producing energy for the cell, and vacuoles, which are large, membrane-bound structures that store water and other substances.
Overall, plant cells are important for a variety of functions in plants, including providing structural support, producing energy, and performing photosynthesis.
