1. <span>tRNA is the one carrying amino acids
2. </span>Mutation does not always affect the evolution of a species because <span>not all mutations affect an entire species.
3. </span><span>The type of chromosomal mutation that occurs here is an example of a deletion mutation. Specific genetic data, or DNA is removed and the remaining portions of chromosomal information have rejoined.
4. </span><span>A chromosomal deletion mutation
5. </span>The mutagens that result in cancer damage DNA by (b) weakening the DNA strand or interfering with base pairing. This mutagens are called carcinogens, if they cause a damage to a gene that makes a DNA repair protein, it means that a cell will have less ability to repair itself, and ,as a result, this will lead to formation of cancer.
These reactions must absorb the energy from their surroundings. Can be cold or heat.

Answer:
The hormone oxytocin aids the birth process by stimulating: uterine wall contractions.
Explanation:
Oxytocin is a hormone that is released naturally in the body of women and that intervenes in certain physiological processes, activating behaviors at a mechanical level in specific organs such as the uterus and the breasts. In the case of the uterus, oxytocin stimulates and maintains the contraction of the smooth muscle of the uterus during labor and delivery, that is, it is responsible for the existence of contractions, which occur during intercourse, due to the distension of the uterus that occurs produced during labor.
Answer:
The correct answer is B. Pond.
Ponds are pretty small and shallow, so the heating from the air and sun gets distributed evenly across the water.

The probability of Sean to both sing and dance well is 50%.
<h3><u>Explanation:</u></h3>
The gene that is dominant is expressed in phenotype of the individual and the genes are actually obtained from the parents.
Here two characters are mentioned which are singing and dancing.
The dominant character i.e able to sing is marked by gene S and the corresponding recessive allele is marked by gene s.
Similarly, the ability to dance is marked by gene D and recessive allele is marked by gene d.
So, the mother is heterozygous and she can sing well, but can't dance. So her genotype is Ssdd.
The father can't sing and is homozygous, so his genotype is ssDD.
Gametes from the mother is Sd and sd. While the gamete from the father is sD.
So the probabilities of the progenies are SsDd and ssDd.
So the probability of Sean to both sing and dance well is 50%.
