When cells do not
respond to the signals that normally regulate cell division, cancer results. Cancer cells altered cell division in the
presence of signals that normally inhibit cell growth, with this; they no
longer require special signals to induce cell growth and division. The consequence
of the abnormalities of these cells could lead to mutations in protein-encoding
genes that regulate cell division.
<span>Moreover, they
also inhibit the growth of nearby cells that allow the cancer cells to spread
and invade other tissues. The uncontrollable division form masses of cells
called tumors that can impaired nearby tissues. If these cells stay in their
original site, they are considered benign, if they become invasive, they are
considered malignant which means that cancer cells metastasize, sending tumor
cells to distant locations in the body where new tumors may form.</span>
Phosphorus: a vital source of animal nutrition. Phosphorus is one of the most important minerals in animal nutrition. It is the second most abundant element in an animal's body after calcium, with 80% of phosphorus found in the bones and teeth, with the remainder located in the body fluids and soft tissue.
The green organisms collected from the pond by Ricardo may be plants or protists. It is required to key out these organisms so that they can be differentiated. In order to determine whether or not these organisms are plants, he should check for the key features of plants, such as whether or not the organisms do photosynthesis. and whether these organisms are multi-cellular or unicellular.
The protists may also contain chloroplasts and cell wall made up of cellulose. Therefore, testing for the presence of these features will not help in determining whether the collected organisms are plants or not.
Hence, he should check whether the organisms are capable of doing photosynthesis or not.
Answer:
If a non native species got introduced then it would hurt the animals already there because there is no animals that are hunting it down. Also it would cause a imbalance in the food chain which can cause so animals to become extinct. If the animal is left unchecked then that animal can become the best in the food chain because nobody can get rid of it.
Explanation:
To defend themselves most likely.
