Which statement correctly describes the structure of a centriole? A) 3 groups of 9 microtubules B) 4 groups of 6 microtubules C)
amid [387]

The right answer is D) 9 groups of 3 microtubules

Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.

What is the purpose of the hormone thyroxine, which is produced by the thyroid gland?
shepuryov [24]

The principal function of thyroxine is to stimulate the consumption of  oxygen and thus the metabolism of all cells and tissues.

Thyroxine is termed T4. It travels through the blood to the target cells and becomes converted to triiodothyronine  or T3.

T3 is the active form of thyroxine. T3 enters the target cell's nucleus binding to genes responsible  or involved  in the metabolism of sugar in the body. T3 stimulates these genes and in so doing metabolism (conversion of oxygen and calories to energy) is carried out by the cell, which also results in generation of body heat.

Several scientists from different countries are asked to examine the results of an experiment before a journal will print it.
Minchanka [31]

Answer:

peer review

Explanation:

In science, results or findings from an experiment are usually published in journals. However, before they can be published, they have to undergo series of confirmation. One way to do this is to have several other scientists examine the results before finally publishing it. This is called PEER REVIEW.

PEER REVIEW is the process whereby an article that is about to be published in a scholarly journal is reviewed by researchers or scientists from the same field of study as the original scientist in order to ascertain the quality and validity of the result or findings. A peer-reviewed article is deemed to be of a very high quality.

2. What are three characteristics of carbon that contribute to the diversity of organic compounds?
TEA [102]

Catenation:

The property of self linkage among identical atoms to form long chain compounds is known as catenation. Carbon exhibits maximum catenation, when compared to elements like sulphur and silicon, due to strong carbon-carbon bonds and tetra valency. Due to this catenation, carbon atoms can form various types of straight chains, branched chains and ring structures.

Formation of multiple bonds:

Carbon atoms are capable of forming multiple bonds with other carbon atoms.

Hydrocarbons:

All the carbon compounds which contain just carbon and hydrogen are called hydrocarbons.

isomerism arises from the difference in the structure of carbon chain which forms the nucleus of the molecule. It is, therefore, named as chain, nuclear isomerism or Skeletal isomerism. For example, there are known three pentanes which have the same molecular formula.
