Answer:

Extra chromosome, missing chromosome or damaged chromosomes

Explanation:

Genetic disorders can be seen/detected from a karyotype photograph. a Karyotype represents the number and visual appearance of the chromosomes in the cell nuclei of an organism.

Karyotype is a laboratory technique that is used to produce the image of chromosomes of an individual in the laboratory . this technique is used to detect the presence of genetic disorders in an individual because and individual is supposed to have 26 pairs of Chromosomes and if it is less or more in the Karyotype its means there is a genetic disorder in the individual.

Answer:

The correct answer is: extra chromosomes, missing chromosomes, and/or damaged chromosomes.

Explanation:

Chromosome abnormalities are a group of genetic disorders characterized by abnormalities in their chromosomes, whether structural or numerical. This type of condition can be detected by a karyotype.

A karyotype is a laboratory technique used to observe all the chromosomes of an individual to see if there are any problems in it. A karyotype is a picture of all your chromosomes.

A normal karyotype shows 23 pairs of chromosomes (46 in total).

When there's an extra chromosome, it receives the name of trisomy (+ the number of the chromosomal "pair" where there's the extra chromosome). For example: Trisomy 21 - Down Syndrome.

When there's a chromosome missing, that is called monosomy (+ the number of the pair where there's a chromosome missing).

Damaged chromosomes can lead to loss of genetic material or translocation of said information.

Do animals get periods? Like females?

Westkost [7]

Yes most of them do. That is one of the main reasons why dogs get spayed/neutered. In order to give birth, You need to of had your period first. So the animals that can give birth have a period. I don't know how long it is though. I am also not sure about fish, just mammals.

Answer:

Explanation:

The arrows in this food web represent energy flow.

A. The energy of the mongoose is passed on to the hare.

The arrows points from the hare to the mongoose, which indicates the energy moving from hare to mongoose. Therefore,A is not correct.

B. The cheetah supplies energy to a variety of organisms.

There are no arrows that point from the cheetah to another organism. The arrows point from the other animals to the cheetah, indicating the cheetah is a top predator. So, B is not correct.

C. The energy of the acacia tree is passed on to the impala.

The acacia tree passes its energy onto termites, and these termites pass their energy onto the impala. Therefore, C is correct.

D. The aardvark, pangolin, and mongoose are all producers.

This is not true, because these are all animals. Producers are typically plants. Additionally, the producers are usually at the bottom of a food web.

So, C is the correct choice.
