Answer:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

what are some examples of neutral mutations and why
Answer:
Examples include silent point mutations, which are neutral because they do not change the amino acids in the proteins they encode. Many other mutations have no effects on the organism because they are repaired before protein synthesis occurs. Cells have multiple repair mechanisms to fix mutations in DNA.

Which of the following is/are TRUE about a cell’s plasma membrane? (CHOOSE ALL THAT APPLY.)
Question 3 options:
Plant cells have a cell wall instead of a plasma membrane.
Proteins are embedded in the plasma membrane and contribute to its function.
The exterior of a phospholipid bilayer is hydrophilic, and the interior is hydrophobic (see figure above).
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Answer:
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Explanation:
Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
The true statement about a cell’s plasma membrane is that the plasma membrane regulates the movement of molecules and ions into and out of the cell. The correct option is D.
What is a plasma membrane?The plasma membrane or cell membrane is the outer covering of the cell. It is made up of lipids and proteins. Cell membranes serve to separate and group cells. Every cell has an exterior plasma membrane that controls both what and how much of any given material enters the cell.
Eukaryotic cells, unlike prokaryotes, have internal membranes that enclose their organelles and regulate the exchange of vital cell components. Both kinds of membranes have a unique structure that makes it easier for them to perform the gatekeeping job.
Thus, the correct option is D. The plasma membrane regulates the movement of molecules and ions into and out of the cell.

reasons why digestion of lipids does not occur in the mouth or stomach
The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes called lipases. The mouth and stomach play a small role in this process, but most enzymatic digestion of lipids happens in the small intestine.

ATP would be an example of an inorganic compound.
True
False
Answer:
False
Explanation:
Adenosine triphosphate (ATP) is an organic compound or to be more specific an organic phosphate
ATP are under the category of nucleic acid biomolecule which are composed of organic compounds. Thus the statement is false.
What is ATP ?ATP or Adenosine triphosphate is the energy currency of the cell, organic compound composed of the phosphate groups, adenine, and the ribose sugar, synthesized in Mitochondria, therefore it is called powerhouse of the cell.
The ATP molecule was discovered by German chemist Karl Lohmann, these organic molecules involves the conversion of chemical energy from the digested food and used later for different cellular processes
In ATP molecule there are three phosphate groups present with high energy bonds involved in the liberation of energy after the break down which provides energy for various life processes.
The energy from ATP can be used in cellular processes like biosynthetic reactions, cell divisions, etc., it is mainly produced during cellular respiration where digested product of food can be utilized.
The ATP supply energy for transportation of different molecules, muscle contraction, blood circulation, locomotion and various body movements, switch to control chemical reactions and to send messages
Thus the statement is false.

Chris wrote a few steps to describe how carbon circulates between the ground and living organisms.
Step 1. Trees absorb carbon dioxide in the air and use it to make their own food using photosynthesis.
Step 2. When plants or animals die, they are broken down by decomposers and their carbon returns to the soil.
Step 3. Carbon stays in the ground for long-term storage as fossilized carbon.
If step 1 is removed, which statement best describes the effects of this missing step on the carbon cycle?
More carbon is stored in the ground for long-term storage.
Less carbon is available for plant and animal growth.
More carbon is stored in plants instead of the ground.
There are more fossil fuels available for energy use.
Answer: i think it is less carbon is available for plant and animal growth. if not i'm sorry
The carbon cycle involves the circulation of carbon and its compound in the earth's spheres. Removal of step 1 results in decreased carbon for animals and plants. Thus, option b is correct.
What is the carbon cycle?The carbon cycle is a cyclic movement of carbon in various spheres between the biotic and the abiotic factors. It involves the biosphere, atmosphere, geosphere, and other spheres. Carbon comes from the atmosphere in the form of carbon dioxide.
This carbon dioxide is used by plants to make food in the form of sugar and is consumed by animals as an energy source. If trees utilizing carbon dioxide are removed then less carbon will be available for cellular respiration.
Therefore, option B. removal of step 1 from the process results in less availability of carbon from animals and plants.
