What is the primary cell type involved in humoral immunity?.

1 answer:

6 0

B cells are the major cell type involved in the humoral immune response. When a foreign antigen (one coming from a pathogen, for example) is detected, B cells in the body that recognize that antigen will begin to produce antibodies as a means of fighting off the foreign invader.

just olya [345]

Answer:

Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.

Explanation:

The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.

The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.

Two possible consequences of not regulating marine mining are:

Destruction of the habitat of life forms present on the sea floor, which endangers many species and even forces migration to more stable areas, with consequences on the food chains.
Extinction of marine species that inhabit the seabed. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.

Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes

The question is incomplete. Please read below to find the missing content.

Selection is usually strongest in the male of the species. D) because sperm are small and plentiful, while eggs are large and energy-rich.

Phenotype refers back to the observable traits of an organism as a multifactorial effect of genetic trends and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral residences.

A person's genotype is their specific collection of DNA. extra especially, this term is used to refer to the two alleles a person has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation.

The sum of an organism's observable traits is its phenotype. A key difference between phenotype and genotype is that, even as genotype is inherited from an organism's parents, the phenotype isn't.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes. Why is sexual selection usually strongest in the male of the species?

a. Males are naturally more aggressive

b. Males have a smaller genetic component than females due to fewer X chromosomes

c. Males do not pass on their mitochondria and therefore have more invested in each individual mating event

d. Because sperm are small and plentiful, while eggs are large and energy-rich.
