1. If a strand is given to you, and you have to identify whether it is DNA or RNA how will you identify it?

1 answer:

3 0

One big way to tell a difference is that DNA is double stranded, in the shape of a double helix, while RNA is single stranded. (This is why RNA can leave the nucleus and DNA cannot) There are also factors that affect the difference like how DNA contains thymine, and when RNA makes copies of it, it becomes uracil.

One species called the naked mole-rat, has some unique differences. They have a social structure similar to that of ants and bee

Verizon [17]

Answer:

May be of the environment they live or genetics.

Explanation:

This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized to produce F2. If the capital lette

Galina-37 [17]

Answer:

a) How many genotypes will occur in F2

--The genotypes would be- AA Aa aa BB Bb bb CC Cc cc DD Dd dd EE Ee ee (15 genotypes)

Reason-

This is because, after crossing the parents, the F1 generation would all be Heterozygous dominant since one parent is homozygous dominant, while the other is homozygous recessive.

b) 25% of all F2 genotypes would be recessive across the 5 loci

Reason-

This is because each loci would produce only a 25% chance for a recessive trait, which would results to a general probability of 25% also.

c) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aaBBccDDEE

d) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aabbccddEE

What is (are) the main difference(s) between passive transport and active transport? Group of answer choices Passive transport d

11111nata11111 [884]

Answer:

Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.

Explanation:

Active Transport works against the concentration gradient and therefore needs energy to make it happen

Passive transport such as Diffusion and Osmosis uses the properties of natural movement of particles which moves the molecules from areas of high concentration to areas of low concentration or down the concentration gradient and happens passively without the need for energy

Which of these is a characteristic of cancer cells?

horsena [70]

<span>E. All of these are correct

A normal, typical and functional cell undergoes cell cycle in normal fashion and eventually reaches apoptosis. Yet cancer cells fail to display just some of these characteristics.

</span><span>The cycle cycle; mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells.</span>
