All proteins found embedded in the cell membrane are transport proteins

Answers

Answer 1

Answer:

False!

Explanation:

Answer 2

False: All proteins embedded in the cell membrane are not transport proteins instead they are not just involved in transportation of molecules but also in other functions.

Cell membrane is the outer covering of most of the type of cells except in plants and bacteria where cell wall is the outermost layer.Cell membrane is made up of phospholipid bilayer. The proteins embedded in the cell membrane are not only the transport proteins but proteins that are responsible for cell to cell communication, responsible for maintaining shape of the cell, and those responsible for triggering chemical messengers all are present.

Cellular respiration is a process in which animal cells use ____ taken in from the atmosphere.

1) carbon dioxide

2) hydrogen

3) oxygen

Answers

Answer:

How does cellular respiration work in animals?

When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.

Explanation:

1) carbon dioxide I think hope it helps

We have learned Kepler's Laws, Newtons laws of Motion and Gravity, as well as where planets are in relationship to the sun. Knowing these things can you provide two generalized statements about the planets and yourself or about the planets and the laws.

Answers

Answer:

''Planets moves around the sun with constantly changing speed.''

''The sun uses its gravity to pull the planets towards it''

Explanation:

These two statements describes Newtons laws of Motion and Gravity. With statement 1, which shows the motion of the planets constantly changing due to the attraction of the sun. When the planets come close together to the sun, its orbital speed increases while on the other hand, when the planets goes farther from the sun, its orbital speed decreases. The statement 2 indicates that sun attracts other planets due to its gravity which allow them to move in a curved.

When your muscle cells do not get enough oxygen, fermentation can create?

Answers

Lactic acid. Your body is able to convert it to energy without using oxygen.

Answer:

Your muscles are forced to work without enough oxygen. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce.

Explanation:

When oxygen is not present or if an organism is not able to undergo aerobic respiration, pyruvate will undergo a process called fermentation. Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.

Which statement is False?

A.) Both Eukaryotic and Prokaryotic cells have genetic information (DNA), cytoplasm, ribosomes and a cell membrane.

B.) The cell membrane (made up of lipids) is "semi-permeable" which means it only let's certain materials in and out, and helps keep cells stable, which is known as "homeostatis".

C.) Cells contain a cytoskeleton, which is a collection of fibers that provide support for organelles and aides in the cells internal movements.

D.) Eukaryotes do not have a nucleus, nor do they have "membrane bound organelles", like the golgi apparatus or the endoplasmic reticulum (ER)​

After cell division (mitosis) how does the genetic code of the newly
produced cells compare to the code of the parent cell?

Answers

Answer:

Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.

Explanation:

Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:

G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.

S is the period of DNA synthesis, where cells replicate their chromosomes.

G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.

M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.

about artificial selection, determine if YOU think the benefits of artificial selection outweigh the disadvantages.
PLEASE HELP!!!!​

Answers

Answer:

What YOU think

Explanation:

That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat.
