Which cells of the nervous system protect the cns by phagocytosing viruses, microorganisms, and tumor cells?

alexandr402 [8]

The correct answer is microglia.
Microglia is glial cells found in the central nervous system with the protective role. Because they are the resident macrophage cells, they act as the first and main form of active immune defense. Microglia is constantly cleaning the CNS for plaques, damaged or unnecessary neurons, and infectious agents, like viruses or other microorganisms.

When scientists discuss the Sixth Extinction, they are referring to which pattern in the rate of extinction?

Travka [436]

Explanation:

The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.[3][4][5] The included extinctions span numerous families of plants[6] and animals, including mammals, birds, reptiles, amphibians, fishes and invertebrates. With widespread degradation of highly biodiverse habitats such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, or no one has yet discovered their extinction. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates.

What is the probability that each of the following pairs of parents will produce the given offspring: 1. AABbCc x aabbcc à AaBbC

ICE Princess25 [194]

Answer:

1) AaBbCc, 50% - 2) AAbbCC, 3,125% - 3) AaBbCc is 12,5%.

Explanation:

1º cross.

Parental) AABbCC x aabbcc

Gametes) ABC AbC ABC AbC ABC AbC ABC AbC

abc abc abc abc abc abc abc abc

Punnet Square) Only filled with the progeny genotype AaBbCc.

ABC AbC ABC AbC ABC AbC ABC AbC

abc AaBbCc --- AaBbCc --- AaBbCc --- AaBbCc ---

F1 Genotype) 32/64 AaBbCc

32/64 AabbCc (shown as the symbol "---" in the

punnet square)

The probability of producing offspring with genotype AaBbCc is 50%.

---------------------------------------------------------------------

2º cross.

Parental) AABbCc x AaBbCc

Gametes) ABC ABc AbC Abc ABC ABc AbC Abc

ABC ABc AbC Abc aBC aBc abC abc

Punnet Square) Only filled with the progeny genotype AAbbCC.

F1 Genotype) 2/64 AAbbCC

The rest of the progeny have different genotypes that are represented with the symbol "---" in the punnet square.

The probability of producing offspring with genotype AAbbCC is 3,125%.

F1 Genotype) 8/64 AaBbCc

The rest of the progeny have different genotypes that are represented with the symbol "---" in the punnet square.

The probability of producing offspring with genotype AaBbCc is 12,5%.
