If a cell loses control of gene expression, what happens?
kipiarov [429]

Answer:

Abnormal, unhealthy cells develop

Explanation:

Gene expression is the process through which genes are turned on through transcription, and to some extent through the translation of the mRNA.

Gene expression is highly regulated to ensure the cell can create the correct combination of proteins to carry out it's tasks. If gene expression is out of control, the mRNAs that are transcribed in the cell are not properly regulated, and therefore the proteins in the cell are not regulated. Since proteins carry out essentially every function in the cell, the cell becomes unhealthy, and incorrectly uses its resources.

Accurate control of gene expression also ensures that the cell can perform specialized functions, it is what makes a heart cell distinct from a brain cell, for example. Therefore, if it is out of control, cells will not be specialized correctly.

Which characteristic differentiates amphibians from reptiles?
Stells [14]

Option D – amphibians may use their skin for gas exchange is the characteristic feature of amphibians that differs from reptiles.

Explanation:

The amphibian skin is moist, thin and marbled and supplied by blood vessels running on its surface. The moisture present in the skin dissolves the oxygen present in its surrounding which is absorbed by the blood vessels. Special glands help the amphibians to keep the skin moist.

The very thick and tough scales present on the reptiles prevent them to absorb oxygen through their skin. Hence, they breathe and respire through their lungs.

Amphibians have three-chambered heart. They do not develop amniotic eggs. Adult amphibians although spend much time on land, they breed only in water due to the absence of amniotic sac .

Is rice pudding a homogeneous or heterogeneous mixture?
wel
<span>Rice pudding would be an example of a heterogeneous mixture. A heterogeneous mixture means that different constituents of a mixture can be identified. Rice pudding consists of rice suspended in a cream. It is possible to identify the grains of rice and the creamy part of the mixture. A homogeneous mixture looks the same throughout--you cannot identify individual parts or ingredients. The parts of a homogeneous mixture are said to be uniformly distributed. Rainwater and air are examples of homogeneous mixtures.</span>
