Answer:
c) probably a mixture of DNA and RNA.
Explanation:
DNA and RNA are the two types of nucleic acids present in cells. DNA or deoxyribose nucleic acid is composed of four type of bases ( adenine, thymine, guanine and cytosine ), deoxyribose sugar and phosphate group. RNA or ribose nucleic acid is composed of four types of bases ( adenine, uracil, guanine and cytosine), ribose sugar and phosphate group.
Here, the sample had adenine which could be either from DNA or RNA. Thymine is from DNA. Ribose sugar is from RNA and uracil is from RNA. Hence, the sample has a mixture of DNA and RNA.
The answer is <span>A. DNA→ RNA→ protein→ trait.
According to the central dogma of molecular biology, DNA codes for RNA which codes for proteins.
The sequence of DNA is transcribed into RNA during the process of transcription. RNA is later translated into proteins during the process of translation. The protein is responsible for some trait.</span>
Answer:
The coyote is actually getting 0.5 kg of "energy" by eating 5 kg of bunnies.
Explanation:
At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. According to the 10% rule, to support 1 kg of coyote, 10 kg of the anterior level is needed. To calculate this, we need to multiply the biomass of the coyote by 10 to get the biomass of its anterior level.
If 10 kg of the anterior level (bunnies) are needed to support 1 kg of coyote, we need to calculate how many kgs of a coyote are supported by 5 kg of bunnies.
10 kg of bunnies ------- 1 kg of coyote
5 kg of bunnies --------- X = 0.5 kg of coyote.
The pituitary gland secretes a hormone called antidiuretic hormone (ADH) which reabsorbs water in the kidney from the urine
A person with diabetes being injected with insulin to regulate their blood sugar levels. Insulin is a hormone made by an organ located behind the stomach called the pancreas. ... The islets of Langerhans are made up of different type of cells that make hormones, the commonest ones are the beta cells, which produce insulin. Hope it helps
