Answer:

air density is lower, so there is less heat transfer

Explanation:

Radiation is absorbed by the ground of Earth and this heats the surroundings along with tropospheric air through conduction and convection process. ... Thus, we can conclude that temperature decrease with higher altitude as air density is lower, so there is less heat transfer.

Earlobes can be either attached or detached. The allele for attached earlobes is recessive (e), and the allele for detached earl

TiliK225 [7]

Answer:

Option B, He has a homozygous genotype

Explanation:

A dominant allele is one which will overshadow the expression of recessive allele. Thus, when a dominant allele and recessive allele appears together in the genotype of offspring , only the trait associated with the dominant allele is expressed. Therefore , if a recessive allele trait is to be expressed , the offspring must have both the recessive allele

Let us see case here

A. Allele for attached earlobes is recessive (e)

B. Allele for detached earlobes is dominant (E)

If offspring has EE genotype, then he/she would have detached earlobes

If offspring has Ee genotype, then also he/she would have detached earlobes as in heterogyzous genotype traits of dominant alleles are expressed.

If offspring has ee genotype, then only he/she would have attached earlobes

Genotype ee is a homozygous recessive genotype

How can the body of an animal stay healthy?

Rufina [12.5K]

The answer would be D) fighting disease. Why D) u may ask? well its because number 1, A) making food doesn't really make animals healthy, some animals make their own supply of food and others just go find food rather than create so really no, number 2, B), getting enough sunlight doesn't make it healthy, some animals are underground or in the ocean, so they really don't need sunlight, some sea monsters below we don't know or seen yet have probably been down there without ever coming up for light so no, C) reproducing, animals reproducing wont really make them healthy at all, it will just make more of them so no. But D) yes because when their body fights against the disease it can help them stay healthy.

What do you predict would happen if the spindle fibers were disrupted during metaphase

SVETLANKA909090 [29]

Spindle fibres are important for assembling the chromosomes at the centre of the cell. Without this the chromosomes would not align and the stages cannot procede. Therefore the cell would not divide
