Inter-vertebral discs separate vertebrae from one another. They are cushion-like discs which absorb the shock the body experience during movement and prevent the vertebrae from grinding against one another.

The intervertebral discs, which are between vertebrae, are the parts that prevent the vertebrae from grinding against one another.

The intervertebrals discs act as a cushion; they absorb the stress and shockw that occur during movement, preventing such grinding.

All of the following events occur during normal meiosis except _______. A. two haploid gametes fuse to form a diploid cell B. on

lesya692 [45]

Answer:

A. two haploid gametes fuse to form a diploid cell

Explanation:

Meiosis is a type of cell division. When a parent cell with "2n" chromosomes enters the process of meiosis, four daughter cells each with "n" chromosomes are formed. This occurs since homologous chromosomes separate from each other during anaphase-I. However, meiosis does not include the fusion of two haploid cells. The fusion of two haploid cells mainly occurs during the process of fertilization during which a haploid male gamete and a haploid female gamete fuse to form a diploid zygote.

Identify a scenario where an experiment would be replicated

Vsevolod [243]

Answer:

If you did not follow the procedure as you should have.

Explanation:

You may have to repeat an experiment for several reasons. It can be because you need to be certain of the results so that you have to perform it several times. Or you need more precise results so that you can fine-tune the variables and repeat the experiment again.

The most common scenario where an experiment would be replicated would be in a situation where you did not follow the procedure that you have outlined exactly like you should have so that the results you got are not 100% reliable. In such a case, the experiment would need to be replicated for the correct results.

I hope this answer helps.

Answer:

Autotrophs are organisms that use light energy or energy stored in chemical compounds to make their own food.

1st order heterotrophs are organisms that eat only plants

2nd order heterotrophs are organisms that eat herbivores

3rd order heterotrophs: organisms that eat herbivores and other carnivores

Top group: carnivores

Explanation:

Producers are named as such because they produce their own food either by photosynthesis or chemosynthesis. These organisms are called autotrophs and include plants.

There are various levels of consumers. The first is first order heterotrophs, which feed on the producers. These are herbivores and include, for example, a deer feeding on grass.

The next is second order heterotrophs, which feed on the first order heterotrophs. E.g. an owl eating a mouse. These are carnivores

The next layer are also carnivores, third order heterotrophs which eat second order heterotrophs, for example a lion eating a zebra.
