The true statements are:
Only a fraction of matter consumed at lower trophic levels is transferred to higher trophic levels to produce growth and release energy through cellular respiration.
And
There are fewer organisms at the higher trophic levels of a food web.
These first statement is actually the reason for the second.
If the sister chromatids do not line up, then there wouldn’t be an equal amount of chromosomes in each of the daughter cells
Answer:
Chloroplasts in the cytoplasm of the cell
Explanation:
The options you were given are the following:
- nucleus is located inside of the cell
-
numerous cilia on the outside of the cell
-
chloroplasts in the cytoplasm of the cell
-
a thin membrane around the edge of the cell
The organelles that would indicate that the observed cell belongs to a plant rather than an animal are chloroplasts. Chloroplasts are organelles that conduct photosynthesis - a process in which plants (and some other organisms that possess chloroplasts) get food. In this process, with the help of sunlight, plants transform carbon dioxide, water, and minerals into oxygen, which is released into the atmosphere, and glucose, which they feed on.
Both animal and plant cells have a cell membrane and the nucleus located inside of them.
The cilia are usually found in animal cells.
This is why the third option is the correct one.
Answer:
Genes
Explanation:
Hereditary information is stored in genes, which are found on each cell's chromosomes. Each gene contains a single piece of information. An individual's inherited trait can be determined by one or more genes, and a single gene can influence more than one trait. There are thousands of different genes in a human cell.
<span>When a cell is placed in an isotonic solution, the cell will not exprience a change in size. This is because, an isotonic solution is one which contains two different solutions which have the same osmotic pressure across a semi-permeable membrane. This makes it possible for water to move freely across the membrane without changing the concentration of the solutes on either side of the membrane. Thus the cell will not exprience any change in size. Cells placed in an hypertonic solution will shrink because water will be moving out of the cell.</span>
