When referring to cell division, oncogenes are most like ________ while tumor suppressor genes are most like ________. the brakes on a car; the gas pedal on a car the steering wheel on a car; the gas pedal on a car the gas pedal on a car; the brakes on a car the brakes on a car; the steering wheel on a car
Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.
Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.
Some examples of oncogenes are growth factors such as, for example, the Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).
Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.
A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

how does oxygen have a direct effect on sea urchins
Answer:
When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through its body (through the canals). Carbon dioxide (waste/not good stuff) is released through the anus. The Purple Sea Urchin obtains oxygen through diffusion only (the diffusion of oxygen into the organism).
Explanation:
Brainliest please
Sea urchins breathe through their feet tubes because of nonavailability of lungs and gills in them. When the oxygen level is low at that time, the sea urchins pump fluids through their anus.
How are sea urchins able to survive sea ?Sea urchins are able to survive in sea because of the tiny hair called spines present on their body as water currents are created because of the hair and waste gets washed away with the water currents created.
When the carbon dioxide level gets increased in the sea at that time the skeletal structures of the marine animals are also affected.
The shells made up of calcium also gets affected because of the increasing acidity in the water. Carbon dioxide not so good is released through the anus and this totally affects the normal regulation of the creature.

Answer:
B. Prokaryote
Explanation:
Because it does not have a well defined nucleus and bound organelles
Answer:
B
Explanation:
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle.In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. ... Throughout the course of evolution, organelles such as mitochondria and chloroplasts (a form of plastid) may have arisen from engulfed prokaryotes.

What is the source from where organisms get glucose?
This is apart of cellular respiration
Answer:
The source of glucose molecules in plants is the product formed by the process of photosynthesis which is ultimately stored in the parts of plants. In animals, glucose is formed by the oxidation of carbohydrates which are obtained from food.
Explanation:
In the process of photosynthesis, plants and other photosynthetic producers create glucose, which stores energy in its chemical bonds. Then, both plants and consumers, such as animals, undergo a series of metabolic pathways—collectively called cellular respiration.
How does ATP store energy and how is it released for cell processes
Answer:
Explanation:
In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work

A. a buffering solution
B. extra substrate
C. an acid
D. a base
Answer:
maybe the answer is C..sorry if i wrong
If an experiment was being conducted using an enzyme that was very sensitive to changes in pH, a buffering solution must be added in order to prevent the enzyme from denaturing. Thus, the correct option for this question is A.
What is the denaturation of an enzyme?The denaturation of an enzyme may be defined as a process through which a molecular structure of an enzyme gets deviate from its original state due to exposure to high temperature, pH sensitivity, etc.
The function of a buffering solution is to stabilize the pH of the given solution. It helps the other component of the solution to resist in response to pH change. A Buffer solution is capable to neutralize the effect of the small amount of acid or base.
Therefore, a buffering solution must be added in order to prevent the enzyme from denaturation. Thus, the correct option for this question is A.
