A control group is needed to carry out the experiment, that control group is the one that is not injected with anything. Ethanol and pesticide need to be injected into separated groups to document whether it is one or the other that is harmful
Depending and what kind of whale, yes
Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity
Answer:
Transport as well as storing of microbes
Explanation:
An agar slant is usually defined as a closed culture tube that is partially filled up with agar mix like nutrient agar. These slants are build-up by allowing agar to reach its boiling point and eventually putting it inside a test tube.
Agar slants are mostly used in order to customize the bacterial cells for their identification. When the bacterial cells are placed over a nutrient agar slant, then it splits rapidly and there produces numerous cells within a couple of hours that are helpful in studying by the use of a microscope. It facilitates the transport and storing of microbes.
Prophase - Chromatin condenses into chromosomes, and spindles begin to form.
