Other guy wrong, its:
A
Mode of reproduction for Escherichia coli, a prokaryotic organism
B
Can occur in animals through fragmentation
The statements that are true for asexual reproduction are the mode of reproduction for Escherichia coli, a prokaryotic organism, and can occur in animals through fragmentation. The correct options are A and B.
What is asexual reproduction?Asexual reproduction is the type of reproduction in which there is no need for two parents. A single parent can generate offspring. They are of various types like budding, and binary fission. It is done in small organisms or primitive organisms.
Escherichia coli is a prokaryotic organism. It is a bacterium that reproduces by asexual reproduction. In bacteria, the cells of bacteria divide themselves and produce new cells called daughter cells.
Fragmentation is a process of reproduction in which there is the fragmentation of a body part that produces a new organism. It can be seen in a starfish.
Thus, the correct options are:
A. Mode of reproduction for Escherichia coli, a prokaryotic organism
B. Can occur in animals through fragmentation.

How do small food molecules such as glucose get from ur gut to the cells
Answer:
The cells along the small intestine use primary active transport to ensure that glucose only flows one way: from digested food to the inside of cells. Active transport proteins use adenosine triphosphate (ATP), the cell’s energy storage molecule, to pump glucose into the cell, either with or against the concentration gradient.

A biology teacher placed a chicken egg in vinegar to dissolve the shell exposing the cell membrane. the teacher then placed the egg in a solution of sodium chloride in water in order to demonstrate cellular transport what type of cellular transport is the teacher demonstrating?
A. facilitated diffusion
B. active transport
C. filtration
D. Osmosis
I would assume osmosis, as sodium chloride is just salt and salt travels to water, which is abundant in the egg.
Option D. osmosis is the cellular transport is the teacher demonstrating in the given case.
Osmosis is the flow of water through a semi-permeable membrane from an area of higher water concentration to an area of lower water concentration. When the egg was placed in a solution of vinegar,
vinegar reacts with the eggshell, bubbles surround the egg and dissolve the shell.It is known vinegar is a weak acid diluted with lots of waterWater moves from the vinegar, through the egg’s semi-permeable membrane, into the egg due to osmosis.When the egg was placed in the salt solution that had a higher concentration of water than was inside the egg,
water moves into the egg.The egg will become larger when placed in the salt solution due to the solution’s low salt concentration and sinks in the solution.Thus, the correct answer is - option D. osmosis.

you are pushing a box to the right with a force of 15n. The friction from the floor opposes the movement with a force of 5n. What is the net force
Answer:
10n
Explanation:
15n-5n=10n
Since the floor opposes the movement you would subtract the amount of friction(5n) from the total force that it was being pushed by (15n), thus you would get 10n.
