2. Enzymes that remove a phosphate from proteins
3. Genes that code to destroy a cell if it becomes cancerous
4. Chemicals that slow down the growth of cells
Answer:
If this didn't help then vote me 1 star. Thanks.
Explanation:
Two groups of proteins, called cyclins and cyclin-dependent kinases (Cdks), are responsible for the progress of the cell the. A phosphatase is an enzyme that removes a phosphate group from a protein. Together, these two families of enzymes act to modulate the activities of the proteins in a cell, often in response to external stimuli. Rough the various checkpoints. What genes destroy cancerous cells? The primary function of the p53 gene is to repair or destroy defective cells, thereby controlling potential cancerous cells. This type of gene is called an anti-oncogene or tumor suppressor gene Cancer growth blockers are also called cancer growth inhibitors. They are a type of targeted cancer drug. Our body makes chemicals called growth factors that control cell growth. Cancer growth blockers work by blocking the growth factors that trigger cancer cells to divide and grow. There are many types of cancer growth blockers that work in different ways..
Imagine that you are managing a large wildlife preserve that was formerly a cattle ranch. You know from historical accounts that wild sheep used to live there, but they were hunted until the local population was exterminated. After doing some research to determine what might be an appropriate starting population, you introduce them. Food is abundant and they have no natural predators. You then spend several years graphing the number of individuals (on the vertical axis) against the number of generations (on the horizontal axis). By the 10th generation, the population begins to reach carrying capacity.

What BEST defines this mathematical model used in population studies?
The mathematical model used in this population study is known as the logistic growth model.
What is logistic growth model?The logistic growth model is a mathematical model that is used to describe the growth of a population over time. It is based on the idea that the growth of a population is limited by resources such as food, habitat, and space, and that as the population grows, the rate of growth begins to slow. This results in a curve that starts out steep and then levels off as the population approaches its carrying capacity, which is the maximum population size that can be sustained in a particular environment.
In the scenario described, the population of wild sheep is introduced to a wildlife preserve where food is abundant and there are no natural predators. This means that the population is able to grow at a relatively fast rate, but as the population increases, it begins to approach the carrying capacity of the preserve. At this point, the rate of growth begins to slow, and the population levels off.
This is reflected in the graph, which shows the population increasing rapidly at first and then leveling off as it reaches carrying capacity. The logistic growth model is often used to understand and predict the growth of populations in a variety of contexts, including agriculture, biology, and economics.

What are the advantages and disadvantages of seed and spore reproduction? Justify whether seed reproduction or spore reproduction is more beneficial for the continuation of an organism.
hi have a great day
No Water Required
Seeds do not necessarily need water to germinate and grow, although some require water to soften the seed coat. Large seeds in dry conditions will hold water and allow the growing plant to grow deep roots without the need for rain or additional water.
Fully Developed Embryo
Inside each seed is a fully developed embryo that is ready to begin growing. Many seeds go through a dormancy period, which is a period when the seed will not germinate and begin growing. When conditions are right, the embryo germinates and begins growing. Having an embryo already grown gives a seed plant a better chance at survival as opposed to a spore.
Nourishment
Each seed contains nourishment for the embryo inside the seed. The endosperm is the tissue that surrounds the embryo inside the seed. The embryo uses nourishment provided by the endosperm as a jump start to begin growing.
The Seed Coat
The seed coat is one major advantage seeds have over spores. A spore is a single-celled organism that develops into a plant or fungus when the conditions are right. The spore has no outer protection.

14. How are photosynthesis and cellular respiration opposite in terms of oxygen?
produces less energy than aerobic respiration.
Answer:
1. Glycolysis
2.false (not sure)
3. Cellular respiration is the process through which cells convert sugars into energy.
4 C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy)
5. Fermentation is a chemical process by which carbohydrates, such as starch and glucose, are broken down anaerobically.
6 anaerobic
7 alcoholic and lactic acid.
8 Alcoholic fermentation is a biotechnological process accomplished by yeast, some kinds of bacteria, or a few other microorganisms to convert sugars into ethyl alcohol and carbon dioxide. ... Alcoholic fermentation begins with the breakdown of sugars by yeasts to form pyruvate molecules, which is also known as glycolysis.
9 In this reaction, a phosphate group (in red) is transferred from phosphocreatine to ADP to form ATP very rapidly, allowing muscle contraction to continue for about 10 seconds. When phosphocreatine is depleted, the muscles must turn to metabolism of fuel molecules to produce more ATP to power physical activity.
10 At this point, the runners' muscle cells are producing most of their ATP by lactic acid fermentation, which can usually supply enough ATP to last about 90 seconds.
12 After that, the body begins to break down other stored molecules, including fats, for energy. If photosynthesis is the process that "deposits" energy in a "savings account," then what is cellular respiration? It is the process that "withdraws" energy.
13 Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2).

. What is the width of Grandmother’s pelvis, measuring from the pelvic brim? How does her pelvis differ
from Grandfather’s?
The width of Grandmother’s pelvis, measuring from the pelvic brim is 2cm.
The grandmother has a wider pelvis than the grandfather.
The pelvic brim is found at the edge of the pelvic inlet and measures around
2cm. The pelvis in females are always wider than those found in males. This
is due to the adaptation of the female pelvis to child birth.
The pelvis being wider aids the passage of the foetus from the womb and
eases childbirth. This is the reason why the grandmother has a wider pelvis
than the grandfather.

Help asap !!!! Which of these statements is true of the brightest stars? (1 point)
O They are yellow stars.
O Many are supergiants
O Several are white dwarfs.
O Each is part of the main sequence.
Answer:
Many are supergiants.
Explanation:
A star's size and core temperature determine its brightness. The brightest stars tend to be blue or blue white. Supergiants and red giants are in the region above the main sequence of stars, so that isn't true. Red are the dimmest. Yellow stars are in the middle of that spectrum. White Dwarfs are dimmer than the Sun, red giants and blue supergiants.
