Answer:
D. the 23rd pair of chromosomes
Explanation:
Humans have a total of 23 pairs of chromosomes. Out of a total of 23 pairs, 22 pairs are autosomes. Autosomes are the chromosomes that carry the genes for all the genetic traits but are not involved in the sex determination of the individuals.
The 23rd pair of chromosomes in humans is of sex chromosomes as these chromosomes carry the genes to regulate the gender of the individuals. A human female has two copies of the X chromosome as sex chromosomes while human males have one X and one Y chromosome as their sex chromosomes. The Y chromosome carries "SRY" gene that codes for testes determining factor and regulates the development of testes in the embryo.
This would be true. the rust cray fish is an aggressive type that competes for food
It increases ecosystem productivity, protects fresh water resources, and provides nutrient storage and recycling
The molecules doesn't need energy to cross through.
The diffusion doesn't need protien, the molecules pass between phospholipids by passes protien. It moves smaller molecules. Facilitated need protien also hormone, and larger molecules.
I wish it makes sense.
Algae live in bodies of water and damp places and are commonly found in both aquatic and terrestrial environments. Terrestrial algae mostly live in moist, tropical areas. They prefer wet places, because they do not have vascular tissues and the other necessary adaptations to survive on land.
