Answer:
Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumors.
Explanation:
Amino acid sequences can be defined by a percentage of identity. This percentage indicates the number of identical residues between proteins or nucleic acids of a given alignment.
- In this case, 240 aminoacids is the total length of the protein alignment (i.e. the alignment between FP1 and FP2 proteins)
- In consequence, in this case, the percentage of identity is 99.58% because dissimilarity is equal to 1/240= 0.0041667%, thereby percentage of identity is equal to 100 - 0.0041667 = 0.995833%.
- Nucleic acid (either DNA or RNA) sequences and amino acid sequences can be defined by the percentage of identity.
- The percentage of identity can be used to discover proteins or protein regions (i.e., domains, linear motifs, etc) which exhibit homology, i.e., proteins/protein regions that are similar due to a common evolutionary origin.
In conclusion, the percentage of identity is determined by the number of identical nucleotides (DNA and RNA) or amino acid residues (proteins) over the total of nucleotides/amino acids in the local alignment.

Mushroom is probably the right answer
Answer:
This question is incomplete and lacks options, the whole question is:
Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as -
Options are:
A. geotropism
B. transpiration
C. phototropism
D. photosynthesis
The correct answer is c.
Explanation:
Phototropism is known as a natural and organic movement of a plant towards the light. This is due to the natural ability of a plant to change direction based on changes in lighting in the environment. But external stimulus is not enough. It must generate some changes inside the plant that make it react in this way: hormones. A hormone is a chemical substance produced in one tissue and transported to another, in which it exerts one or more highly specific effects.Auxins are members of a group of plant hormones that are more beneficial to stimulate plant growth, it is the responsible mechanism of the response to phototropism in plants, which tends to be concentrated in the region of the stem and leaves, when a plant lacks this, it can be noted since the bending towards the light source is little or no, that is, auxins make the cells of the stem growth region (rhizomes and stems) lengthen.
A. mechanical waves.
Basically, they need particle interaction which includes having a medium to transport their energy from one place to another.
