Answer:

(D) They are all acids

Explanation:

Amino acids are monomers, fatty acids are polymers and they do not contain nitrogen. All four are acidic in nature for different reasons:

Amino acids due to acidic carboxyl group -COOH.
Fatty acids due to end chain acidic carboxyl group -COOH.
Nucleotides because they have phosphate groups (which are acidic in nature).
Monosaccharides due to presence of aldehyde group -CHO (which can oxidise to -COOH).

Answer:

Color of light/Type of light

Explanation:

B/c by definition of independent variables, these are the variables that are manipulated to see how it affects the other value (which is aka dependent variable). Color of light is independent because you have multiple manipulation which can be clearly seen in the different types of lights and the height is dependent on what color of light it is exposed to.

Additionally,

Dependent variable - the height of the plant

An independent variable is not affected during the experiment. It is what experimenter controls. The dependent variable is called dependent because it depends on the independent variables. Here, the height of the plant depends on the color of the light, therefore the height of the plant is dependent variable and the color of the light is the independent variable.

Organisms with the genotypes aabbccdd and aabbccdd are crossed. What are the expected proportions of the following progeny?

Dvinal [7]

Answer:

a) $\frac{27}{64}$

b) $\frac{1}{32}$

c) $\frac{27}{64}$

d) $\frac{3}{64}$

Explanation:

The correct question is

Organisms with the genotypes AABbCcDd and AaBbCcDd are crossed. What are the expected proportions of the following progeny?

a. A_B_C_D_

b. AabbCcDd

c. a phenotype identical to either parent

d. A_B_ccdd

Solution

In such question the probability for each allele pair is to be determines separately

For instance,

AA * Aa will produce AA, Aa, AA, Aa this means that all the the probability of getting both AA and Aa is $\frac{1}{2}$

Like wise when Bb and Bb are crossed, BB, Bb, Bb, and bb are produced. So the probability of getting dominant trait i.e BB or Bb is $\frac{3}{4}$ and recessive trait i.e bb is $\frac{1}{4}$

Chance to get homozygous bb only or BB only is $\frac{1}{4}$

and chance of getting Bb is $\frac{1}{2}$

Like Bb and Bb cross, the same will be the probabilities for Cc and Cc cross and Dd and Dd cross

Part A)

$\frac{1}{4} * \frac{3}{4} * \frac{3}{4} * \frac{3}{4} \\= \frac{27}{64}$

Part B)

$\frac{1}{4} * \frac{1}{2} * \frac{1}{2}* \frac{1}{2}\\= \frac{1}{32}$

Part C)

$\frac{1}{4} * \frac{3}{4} * \frac{3}{4} * \frac{3}{4} \\= \frac{27}{64}$

Part D)

$\frac{3}{4} * \frac{1}{4} * \frac{1}{4} * \frac{1}{4} \\= \frac{3}{64}$

puteri [66]

Answer:

The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes.
