An extra chromosome will produce an aneuploidy. It may have severe consequences on the resulting zygote.

<h3>Aneuploidies and chromosome abnormalities</h3>

The term 'chromosome abnormalities' refers to different types of problems that occur in meiosis which are associated with the disjunction of chromosomes.

The most common chromosomal abnormality is called aneuploidy, which means an abnormal number of chromosomes.

Aneuploidy is caused by the presence of an extra or due to the lack (missing) of a chromosome during meiosis.

For example, a trisomy is an aneuploidy due to the presence of an extra chromosome (three copies of the same chromosome instead of two).

mylen [45]

The correct answer is: Individuals that produce chemical compounds are better protected from herbivores and are able to produce more young than individuals that do not produce the compounds.

Natural selection acts on variations-differences in phenotype that exist among individuals. If a certain trait contribute more to survival and reproduction (individuals with that variant survive more than individuals with other variant), natural selection will favor that trait. In this case, production of chemical compounds is favored over non-producing trait.

How are tigers and goldfish are related in two different ways?
11Alexandr11 [23.1K]

Tiger is a top predator in the jungles of Asia and the goldfish is a small species of fish selectively bred in China and they are not at all related.

All living things have the same way of transferring genetic information, trough the DNA molecule. Genetic analyses showed that the last common ancestor (LUCA) of all organisms on Earth has lived 3,5 billion years ago. After that, all living things diverged into separate groups. Tigers and goldfish both are animals and have a common ancestor. Tigers may be in a close relationship with other big cats like lions and cheetahs, but they all have a common ancestor with the goldfish since all vertebrates have a common ancestor that was an ancient fish species.

What is NOT true about the evidence that fossils provide?
aleksandrvk [35]

Answer:

C. All fossils contain intact DNA that can be sequenced.

Explanation:

Fossils are the impression, trace or preserved remains of once-living thing from past thousands of years such as bones, exoskeletons, objects preserved in amber, and stone imprints of animals or microbes.

Fossils provide evidence about seevral characteristics and features of extinct organism such as evolutionary relationship between organisms and  transitional forms between groups of organisms. but all the fossil do not provide evidence about the intact DNA that can be sequenced because some fossils carry DNA rumnants which do not have the ability to get sequenced.

Hence, the correct option is C.
