Blizzard [7]
<span>In their book "Interaction between temperament and environment" behavior geneticists Robert Plomin and Denise Daniels state, "Two children in the same family are [apart from their shared genes] as different from one another as are pairs of children selected randomly from the population." There may be many reasons children in the same family are so different from one another but their finding boils down to the environment. To a large extent the environment influences personality, psychopathology, and cognitive abilities. Environmental differences between children in the same family represent the major source of character and environmental variance.</span>

The Gulf Stream passes from the Gulf of Mexico, northward along the coast of eastern North America, and eastward toward Ireland,
anzhelika [568]
I believe it is keeping these regions warm because the water is flowing from the SOUTHERN part of these regions, like, how it starts from the bottom of the US, (aka Louisiana, Mississippi), and it gradually flows upward, but hot always overrules cold, so the cold water that it is flowing into is becoming warmer as it passes into the warm water from the gulf of Mexico.
Hope that this helps :)

The allele for brown fur in mice (B) is dominant over the allele for white fur (b).
evablogger [386]

Answer:

Genotype: Bb (heterozygous)

Phenotype: brown fur

Explanation:

Since allele B is dominant to allele b, as long as genotype has allele B in it, its effect of phenotype will be expressed instead, regardless of whether allele b is present.

As mouse genotype is stated as Bb, on the chromosome from its parents, allele B comes from one parent while allele b is inherited from the other parent.

Phenotype is the expressed trait. In this case, as genotype has allele B, the phenotype will be brown fur as its effect is expressed.

Naily [24]

Nerves tissues are composed of nerves and two types of cells are neurons and glial cells.

<h3>What do you mean by Nervous tissues?</h3>

Neurons are the primary type of cells that are associated with the nervous system, while glial cells may be defined as the neurons of the central nervous system which play an important role in the conduction of nerve impulses, but they are non-excitable cells.

Therefore, nerve tissues are composed of nerves and two types of cells are neurons and glial cells.
