Answer:
The possible fate of the cell that it may turn cancerous.
Explanation:
The cells present in the body generally work in harmony. However, if a cell attains a mutation, it can make it proliferate in the case when it should not do, and make it thrive in the case when other cells are dying. Due to proliferation, the unusual cell produces more abnormal cells also known as cancerous cells. These cancerous cells become more favorable in comparison to the normal cells due to the phenomenon of natural selection. These cells eventually result in a lethal form of tumors.
In the normal cells, the destructed gene or the damaged cells get repaired easily, in case if the damage is worse the cell dies. A protein known as p53 helps in repairing damaged cells or kills them if the damage is too severe. But in the case of cancer cells, the p53 protein does not work appropriately as they possess a mutated or changed form of p53 protein. Thus, in the case of cancerous cells, the rate of repair lags behind the rate of mutation, which makes the cancer cells thrive and increase in numbers resulting in further destruction.
Hi,
The correct answers should be:
Electrons are smaller than protons
The majority of an atom’s mass is in the nucleus
Protons and neutrons are about the same size.
The first option is not true since in the picture you can see three different kinds of particles, while the second one is false since different electrons can occupy different energy levels and the same electron can “jump” from one energy level to another one if stimulated.
Hope this helps! If my answer was not clear enough or you’d like further explanation, please let me know. Also, English is not my first language so I’m sorry for any mistakes.
Answer:
transport nutrients and water from below-ground tissues to above-ground tissues and grow taller.
absorb nutrients from the soil
Explanation:
The vascular tissues of plants is made of specialized conducting tissues the xylem and phloem.
This tissues form a continuous systems through the plant body and provide pathways for the transport of water, nutrients, signaling molecules and also provide support for plant body against mechanical stresses. The xylem transport water and nutrients from the roots to other parts of the plant while the phloem transport photosynthate the product of photosynthesis from the source where it is produced to other plant part.
Answer:
No. of phenotypes expressed by a gene = (2n + 1)
Explanation:
It is a basic mathematical function that predicts the average number of phenotypes expressed by a gene. In the above function, n represents the number of genes that are expressing themselves.
