Which of the following best illustrates a type I survivorship curve, with higher death rates at older ages? Which of the followi

Rama09 [41]

Answer:

large mammals such as gorillas

Explanation:

The survivorship curves refer to the graphical representation of the proportion of the fraction of survivors or the individuals at a given age.

There are three types of survivorship curves which can be constructed by studying the life history of the organisms.

The type I survivorship curve is the curve which can be formed with the organism which has a high survival rate at the younger and middle age and high death rate at the older age. The type I curve can be characterised by its convex shaped. The type I is showed by the large mammals like gorilla, humans and many others.

Thus, large mammals such as gorillas are the correct answer.

If meiosis failed to occur in both male and female worms the zygote nucleons would resemble diagram

Tetraploidy will occur.

<h3><u>Explanation</u>:</h3>

The process of sexual reproduction is very necessary to maintain the genetic setup of the species over the races.

The normal chromosome content of a cell is called diploid state of cell. Its represented by the expression 2n. The cell division that takes place before the gamete formation is called meiosis. This cell division makes the chromosome number of the cells halved. So haploid cells are produced. Its represented by n.

Now as the gametes fuse, both the n becomes 2n and diploid state is regained.

But if the meiosis don't occur in the gametes, the gametes will remain 2n. So after fertilization, it becomes 4n. This state is called tetraploidy.
