1. Living in herd is an ______adaptation?
Lapatulllka [165]
Living in herd is a structural adaptation.

There are three different kinds of adaptations: behavioural, physiological and structural.

Adaptations help animals survive and their ecosystem. 

The second sentence does not sound correct but it seems correct to me (just not in grammar).

Hope it helped!

4: Units of inheritance known as genes exist in pairs.
Bas_tet [7]

Answer:

4. a

5. a

6. a

7. a

8. a

9. a

10. True

Explanation:

4. Units of inheritance in living organisms are known as genes. These genes exist in pairs in all organisms and a copy of each gene is passed down to the offspring during reproduction.

Correct option: a

5. Assuming the dominance of allele A over allele a:

                AA    x    aa

          Aa    Aa    Aa    Aa

All the offspring will appear tall since the effects of allele a is masked by allele A.

Correct option: a

6. From the cross in (5) above, the genotypic ratio of the offspring is 100% Aa.

Correct option: a

7. Alternate forms of genes in living organisms are known as alleles. A copy of the alleles is usually passed down to the offspring during the process of reproduction.

Correct option: a

8. Phenotypes are the physical appearance of organisms. They are physical interpretation of genes.

Correct option: a

9. The law of segregation was postulated by Gregor Mendel. It states that gene pairs segregate during the process of meiosis and then randomly unite during the process of fertilization.

Correct option: a

10 Heterozygous organisms have two different alleles for the same genes. For genes that obey Mendelian laws, heterozygous condition is characterized by one dominant and one recessive alleles.

Fisher was found lying on his back. Is it likely that his body was moved after death? Why or why not?
Tpy6a [65]

Answer:

Is it likely that his body was moved after death? The answer is NO

Why or why not?

This is due to postmortem staining seen on his back which would have been observed on other parts of the body if the body was moved after death

Explanation:

Livor mortis: is the stage where the heart stops pumping blood through the circulatory system causing blood accumulation at the lowest point of the body. It's also called postmortem stain.

It helps in judging the time of death for a body, the location and position of the body if it's at the spot.
