How do dung beetles help a carbon atom in animal dung to become part of a carbohydrate molecule within a plant?
Ber [7]

Answer:

Dung beetles lives in the animal dung and take nutrients from the undigested substances present in the dung. This dung is mixed with the soil by the beetle to increase the fertility of the soil. These nutrients is taken by plants with water through roots and makes their food in the form of carbohydrate from it in the process of photosynthesis. This carbohydrate is stored in different parts of plant body.

I need help ! i really don’t get it
Vaselesa [24]

Answer:

The presence of an additional chromosome

Explanation:

Look at "pair" 21. See how there are THREE chromosomes instead of TWO? Normally, there would only be two chromosomes in each pair but this karyotype shows a trisomy (see def. below) of the 21st pair. This was caused by a nondisjunction mutation of the 21st pair. The is also the karyotype of a person with Down's Syndrome.

Definition of Trisomy:

A condition of the presence of three chromosomes in a pair instead of two. This normally causes developmental irregularity.

guajiro [1.7K]

Answer:

Platelets would release signals to stimulate the production of more platelets

Explanation:

Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.

In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.

Olenka [21]

This membrane mimics the plasma membrane that is around animal cells. In order to explore how water moves in and out of a cell, one cell was weighed and then submerged in hypertonic solution. The other egg was weighted and submerged in hypotonic solution. It was predicted that the egg submerged in hypertonic solution  would decrease in mass. It was predicted that the egg submerged in hypotonic solution would increase in mass.

Explanation:

The outermost covering of an animal cell is the plasma membrane. It is a selectively permeable membrane that allows only selective molecules to pass through it.

A solution having higher concentration of solute than the cell cytoplasm is called a hypertonic solution.

A solution having lower concentration of solute than the cell cytoplasm is called the  hypotonic solution.

The movement of water molecules from the region of its higher concentration to the region of its lower concentration through a semipermeable membrane is called osmosis.

A cell placed in hypertonic solution will undergo exosmosis so it will lose water and its mass will decrease.

A cell placed in hypotonic solution  will undergo endosmosis of water  so it will gain water and its mass will increase.
