Based on the characteristics above, this toxin can be categorized as EXOTOXIN. These toxins (exotoxins) are produced by different types of bacteria.

Exotoxins are a broad category of proteins produced by bacteria that enter host cells in order to alter their physiological properties.

These toxins (exotoxins) can be secreted by Gram-negative bacteria and Gram-positive bacteria.

Examples of exotoxins include botulinum toxin secreted by <em>Clostridium botulinum</em> bacteria, tetanospasmin toxin secreted by <em>Clostridium tetani </em>bacteria, etc.

There are two alleles, B and b, at a gene locus in a population at Hardy-Weinberg equilibrium. The relative frequency of the dom
viva [34]

Answer:

210

Explanation:

Frequency of dominant allele is represented by "p"

and frequency of recessive allele is represented by "q"

Given

p = 0.7

Thus,

q = 1-p\\q = 1 - 0.7 \\q = 0.3\\

As per Hardy Weinberg's second equation of equilibrium -

p^2 + q^ 2 + 2pq = 1\\

Substituting the given values in above equation, we get -

0.7^ 2+ 0.3^2 + 2pq = 1\\2pq = 1- 0.49-0.09\\2pq = 0.42

So the total number of heterozygous individual is equal to

0.42 * 500\\= 210

Describe the effects that the dams built by beavers (a keystone species) have on other types of organisms.
lianna [129]

Answer:

Beavers and their dams play an important role in nature. Because of the dramatic effects their dams have on surrounding ecosystems, these mammals are considered a keystone species. By constructing dams they create wetlands -- lush environments which attract fish, ducks, frogs and other creatures.
