John had a science fair project that he needed to do. He wanted to test the effects that organic and chemical fertilizers had on

plant growth. John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to water the pots daily. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants.

egoroff_w [7]

Answer:

The correct answer will be option- <em>Streptococcus pyogenes.</em>

Explanation:

M protein is an important virulence factor which is produced and expressed on the surface of <em>Streptococcus pyogenes. </em>

This protein plays important role in the bacterial infection like adherence to epidermal keratinocytes, resistance to phagocytosis,  invasion of epithelial cells and microcolony formation.

The M-protein is a α-helical coiled structure protein which consists of the four distinct regions (A–D) in which  A-region in the N-terminal is highly variable.

Thus,  option- <em>Streptococcus pyogenes</em> is the correct answer.

In humans, the ABO blood type is under the control of autosomal multiple alleles.Color blindness is a recessive X-linked trait.M
kifflom [539]

Answer: 1/4

Explanation:

Firstly, in order for both parents to be type A and have children with type o blood, their blood types must both be Ao. Since o is a recessive blood type, a punnett square shows there is a 25% chance any child of theirs will have type o blood. If neither parent is color blind and they have a son who is, it implies that the mother is a carrier of colorblindness and has the genotype XᴮXᵇ. If you do a punnett square of the not colorblind father (XᴮY) and the mother, it shows that a daughter would have a 0% chance of being colorblind. Therefore colorblindess is irrelevent, since there is no possibility of the daughter not having normal color vision. In conclusion, there's a 25% chance she will have type o blood and not be colorblind, since the other 75% chance would be having type A blood and not being colorblind.

What type of relationship does a cat and tapeworm have?
stellarik [79]

Answer:

Parasitism.

Explanation:

Parasitism is an association in which one organism, lives on another, the host, deriving benefit from it and causing harm to it.

The tapeworm here is a parasite and it lives inside the cat's(host) body where the tapeworm is specialized for its mode of life. It survive and reproduces very well without needing another specie because it is a hermaphrodite. It causes loss or poor development of unwanted organs such as the digestive, sense organs and muscles. Its long flattened body also provides a large surface area for absorption of nutrients too.
