<span>All mammals have at least one X chromosome. Female mammals have two X chromosomes, so each of her eggs has a single X chromosome. Male mammals have XY chromosomes, meaning they can generate sperm containing the X chromosome, or sperm containing the Y. If the egg receives sperm containing the X chromosome, then the resulting individual forms ovaries, and is female.</span>
A woman standing and watching the stars on a cool, calm night will lose most of her body heat by radiation. so correct option is A
The emission or transmission of energy as waves or particles across space or a material medium is known as radiation. Thermal radiation will cause the majority of the woman's heat to escape from her body. Evaporation is not a actual process because evaporation is a cooling process rather than a means of heat transfer since latent heat is lost during the process There will be little convection and conduction in this situation.

The controversy surrounding the nucleic acids and proteins, regarding which one of them was formed first is the most popular controversy in the biology world today. The nucleic acids stores and the genetic information. The proteins essential for all the life processes are encoded by the genes formed of the nucleic acids (DNA and RNA). But proteins (enzymes) are required for the formation of proteins from the genes. The inter-dependency of the nucleic acids and proteins on each other possesses a dilemma to the question 'which of them arrived first'.
The answer to this dilemma was answered when it was discovered that RNA was capable of not only carrying the genetic information, but also acting as catalyst to the chemical reaction. This finding supported the notion that the RNA evolved first serving the purpose of both the nucleic acids and emzymes.
Answer:
any of a large group of vertebrate animals that live in water, breathe with gills, and usually have fins and scales
Explanation:
Hi!
The answer would be: Dominant
<h3>Explanation</h3>
A cross between a true breeding short plant (homozygous for short, suppose tt), and a cross between a true breeding tall plant (homozygous for tallness, suppose TT) would result in all the offspring being heterozygous for the traits, meaning they would each have an allele of shortness (t) and an allele of tallness (T).
Considering the offspring were all tall, we understand that the allele for tallness must have been dominant over the allele for shortness to present itself over it. Hence, the term describing the gene for tallness would be dominant, and the term describing the gene for shortness would be recessive.
Hope this helps!
