What are the characteristics of normal cells and cancerous cells?​

Biology

alisha [4.7K]3 years ago
4 0

Normal cells stop growing (reproducing) when enough cells are present. For example, if cells are being produced to repair a cut in the skin, new cells are no longer produced when there are enough cells present to fill the hole (when the repair work is done).

In contrast, cancer cells don’t stop growing when there are enough cells present. This continued growth often results in a tumor (a cluster of cancer cells) being formed.

<span>The correct answer is cGMP.</span> 
 <span>cGMP, during the dark (when there are no stimulations of photoreceptor cells), reaches high intracellular levels. When the light stimulation occurs cGMP levels decrease because it is converted to GMP by phosphodiesterase. Phosphodiesterase is activated by transducin which is activated by excited rhodopsin (contains photopigment).</span>  
<span>
Low levels of cGMP block the cGMP gated ion channels and that prevents the entry of Na and Ca. Because of that membranes becomes more negative, hyperpolarization occurs and this creates a signal for the next cell.</span>

Artyom0805 [142]

Answer:

Connective Tissues

Explanation:

According to my research on studies conducted by various medical professions, I can say that based on the information provided within the question this scientist is most likely looking at Connective Tissues. These are tissues in which material secreted by the cells is fills up the spaces between the cells, thus connecting or binding otherwise separate tissues or organs. Which is what the scientist seems to be describing.

Answer:

the making of a polypeptide with a specified order of amino acids using an ​ RNA ​molecule to provide the sequence information

Explanation:

<u>Translation is the making of polypeptide with a specified order of amino acids using a RNA molecule to provide the sequence information.</u>

In order word, translation is the process of synthesizing protein from mRNA synthesized from DNA template.

<em>During the process of gene expression, the information in the DNA are first transcribed into a mRNA in the nucleus. Thereafter, the mRNA is transported out of the nucleus to the cytoplasm where the genetic codes present in it are translated into their respective amino acids and become linked together through a peptide bond.</em>

Each polypeptide formed has a specific amino acids which correspond to the codons on the mRNA.
