Answer: D
Explanation:
Many unicellular organisms live in bodies of water and must move around to find food. Most often, they must obtain nutrients by eating other organisms. Plant-like protists, and some types of bacteria, can make their own food through photosynthesis.
Answer:
a. Two of these are correct.
Explanation:
The two correct options are
b. Is a critical component or requirement for wound healing to take place
d. Existing blood vessels give rise or sprout to form new blood vessels
Angiogenesis is the physiological means in which new blood vessels form pre-existing vessels, developed in the starting phases of vasculogenesis. Angiogenesis is a usual and important process in growth and development, wound healing and in the development of granulation tissue.
The growth and maturation of blood vessels is a largely regulated multistep mechanism called angiogenesis.
Answer: The genotype ratio is 2Ff : 2ff
The phenotype ratio is two normal feathered birds to two silky feathered birds.
Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.
A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.

Answer:
The number of protons in it.
Explanation:
There are two properties that can be used to identify an element:
- the atomic number
- the number of protons in an atom.
The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question
When you take blood pressure, it is expressed in a fraction. The top number of that fraction is systolic pressure- the amount of pressure in your arteries during contraction of your heart muscle... I hope this helped! :)
