In evolutionary biology, phylogenetic trees are used to exhibit and illustrate the evolutionary relationships of two or more organisms, and identify the origins of life altogether. To achieve this, there are three methods of classification which are phonetics, cladistics, and taxonomic groups.

the person is correct but also if you want to write it yourself make sure to include:

The three methods are traditional, phenetic, and cladistic.

The traditional method stresses common ancestry and divergence.

The phenetic method is a process by which organisms are grouped together based on the number of similarities.

The cladistic method focuses on shared, derived characteristics not found in other groups.

Galina-37 [17]

Answer:

a) How many genotypes will occur in F2

--The genotypes would be- AA Aa aa BB Bb bb CC Cc cc DD Dd dd EE Ee ee (15 genotypes)

Reason-

This is because, after crossing the parents, the F1 generation would all be Heterozygous dominant since one parent is homozygous dominant, while the other is homozygous recessive.

b) 25% of all F2 genotypes would be recessive across the 5 loci

Reason-

This is because each loci would produce only a 25% chance for a recessive trait, which would results to a general probability of 25% also.

c) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aaBBccDDEE

d) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aabbccddEE

Which of the following statements is true?

mr Goodwill [35]

Answer:

Spongy bone is well adapted to accept stress in many directions, which makes it good for shock absorption

Explanation:

Spongy bone tissue is less compact and always present towards the interior of the bone and is covered by compact bone. Spongy bone tissue has lamellae that are arranged in an irregular pattern. The thin irregular columns of lamellae are called trabeculae.

The trabeculae of spongy bone tissues are precisely arranged along the line of stress. This feature of spongy bones allows them to resist the stress applied from many directions and to transfer the force making them a good shock absorber. The final arrangement of trabeculae is achieved only after the person learns the locomotory movements completely.
