In rabbits, black fur (B) is dominant to white fur (b). A purebred black furred male is bred with a female that had the recessiv

ValentinkaMS [17]

Answer:

All the offsprings will be black-furred (Bb)

Explanation:

This question involves a single gene coding for fur length in rabbits. The allele for black fur (B) is dominant to the allele for white fur (b). This means that a rabbit heterozygous for this gene (Bb) will have a black fur.

According to this question, a purebred black furred male (BB) is bred with a female that had the recessive white fur (bb). The parents will produce gametes as follows:

BB - B only

bb - b only

Using these gametes in a punnet square (see attached image), the genotypic proportion of the produced offsprings is as follows:

Bb, Bb, Bb, Bb

All Bb (heterozygous) means that all of the offsprings will be black-furred.

• 11. Thinking about trophic levels, the type of energy we use from a natural resource comes through a transfer of what, which c

Ber [7]

Answer:

Solar energy

Explanation:

There are different kinds of energy, and one of them is radiation. By concept, radiation refers to the emission, propagation, and transference of energy in the form of electromagnetic waves or particles. Living beings depend on solar energy from their origins.

Throughout the trophic web, there exists a process of energy transference through the different trophic levels, in which every organism feeds on the preceding one and becomes food for the next one. Producers take solar energy and transform it into chemical energy, which is the one from one level to the other.

Energy flow: From the whole quantity of solar energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.

From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

The progressive reduction of energy determines the number of trophic levels (4 or 5).

HOW IS THE BRAIN INVOLVED IN LANGUAGE ACQUISITION

yuradex [85]

The main parts of the brain involved in language processes are the Broca's area, located in the left frontal lobe, which is responsible for speech production and articulation, and the Wernicke's area, in the left temporal lobe, associated with language development and comprehension.
