The correct answer is "<span>It will perform less than optimally unless the pH was increased."

This is because the curve on the graph shows pH versus reaction rate. If we follow the x-axis (the bottom one) to a pH of 7, it is at an extremely low reaction rate compared to other points of the graph. If we continue along, we see that the reaction rate increases as the pH increases. Therefore, the enzyme will perform less than optimally unless the pH is increased.

Hope this helps, and hope I'm the brainiest! :)</span>

1. In the marine food web shown, which of the

Rudiy27

Answer:

C. Ringed seal

Explanation:

A marine food web illustrates how energy is passed from one organism (level) to another in this aquatic rich ecosystem.

In the following food web, the interaction goes like this:

The Arctic cod feeds on plankton and silverslides and it is preyed upon beluga whales and ringed seals.
The sea duck goes to the bottom of the ocean to feed on benthic organisms and also consumes plankton and silverslides. It doesn't really have predators.
The beluga whale doesn't really have predators, but it feeds on fish such as silverslades and Arctic cod.
Ringed seals feed on plankton and Arctic cod and are then consumed by polar bears.

Therefore, according to this information, all organisms except the ringed seal feed directly on silverslides.

let A and a represent dominant and recessive alleles whos respective frequencies are p and q in a given interbreeding population

lesantik [10]

Answer:

A) $48$ %

B) $18$ %

Explanation:

A) Given

Frequency of individuals in the population having recessive phenotypes $= 16$ %

Frequency of individuals in the population having recessive phenotypes is represented by $q^2$

$q^ 2 = 0.16\\q= \sqrt{0.16}\\ q = 0.4$

Thus frequency of recessive genes is equal to $40%$

frequency of dominant genes is equal to

$p = 1-q\\= 1-0.4\\= 0.6$

Now,

$p^2 + q^2+2pq = 1\\2pq = 1-0.16-0.36\\2pq = 0.48$

$48$ % of genes exist in the heterozygous condition

Frequency of individuals in the population having recessive phenotypes $= 1$ %

Frequency of individuals in the population having recessive phenotypes is represented by $q^2$

$q^ 2 = 0.01\\q= \sqrt{0.01}\\ q = 0.1$

Thus frequency of recessive genes is equal to $10%$

frequency of dominant genes is equal to

$p = 1-q\\= 1-0.1\\= 0.9$

Now,

$p^2 + q^2+2pq = 1\\2pq = 1-0.01-0.81\\2pq = 0.18$

$18$ % of genes exist in the heterozygous condition

Which represents the correct order of cell organization after cellular differentiation (simple to complex)? A) organ systemâ†’or

natita [175]

Answer:

D) Cell - Tissue - Organ - Organ system

Explanation:

Cell organization starting from cell to organ system shows the relationship among different levels of cell organization. The cell organization helps to know the structural and function of the organisms.

The correct order of cell organization:

Cell – tissue - organ - organ system

Different organsystems organise to for an organism. The cell is the simplest level and a group of cells (tissue) is the next higher level, a group of a tissues (organ) and a group of organs makes organ system which is the complex level of organization.
