Function of nervous tissue

1 answer:

5 0

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning. To do all these things, cells in nervous tissue need to be able to communicate with each other by way of electrical nerve impulses. The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.

The largest unit within which gene flow can readily occur is a

notka56 [123]

Answer:

a. population

Explanation:

Gene flow cannot occur in hybrids because 99.9% of the time hybrids offspring are not fertile.

At genus level is not possible either because a hybrid is a cross breed at the genus level (horse-donkey).

A population is a group of species of 1 kind. A population of donkeys.

describe and explain the adaptations of sperm and ovum that enables fertilisation and early development of the embryo to occur

Mekhanik [1.2K]

The adaptations of the sperm and egg that allow fertilization to take place, and copulation occurs for the sperm to be deposited. These sperm penetrate the cervix and travel to the fallopian tube. There, they must find an oocyte, which is released in the process of ovulation.

<h3>What is fertilization and embryo development?</h3>

In the first weeks after fertilization, the zygote makes many changes and develops rapidly. The first eight weeks of development is known as the organogenic period and is the embryonic stage of development. This period is a crucial phase of development for the embryo's organs.

With this information, we can conclude that The first three days of embryonic development occur in the fallopian tube as the embryo moves from the ovary to the uterus. Cell division continues and forms a hollow ball of cells (the blastocyst). Six days after fertilization, the embryo begins implantation into the lining of the uterus.

Which of the following steps in preparation of a fully mature eukaryotic mRNA occurs within the nucleus?

kogti [31]

Answer: e. All of the above

Explanation:

The processing of mRNA to a fully mature eukaryotic mRNA requires addition of a 5' cap (Capping) and 3' poly(A) tail ( polyadenylation) to the ends of the transcript, and removal of any intervening introns by splicing. Once processing is completed, the mRNP, which consists of mRNA and associated proteins, is ready for export from the nucleus.
