Would you expect the stomata of a desert cactus or the stomata of a water lily plant to close during the day?

1 answer:

5 0

A water lily will have more stomata. A desert cactus will have very few stomata, because in deserts plants face water shortage so in order to avoid loss of water cacti have adapted to the desert environment by possessing few stomata.

Answer:

E/e ; T/t ⇒ Square eyes and long tail (Option D)
3/16 will have round eyes and long tails (Option C)
1/4 of the progeny will be heterozygous for both traits (Option A)

Explanation:

<u>Available data</u>:

Two diallelic unlinked genes
Gene E controls eye shape: Dominant allele E expresses square eyes, and recessive allele e expresses round eyes.
Gene T controls the tail size. Dominant allele T expresses long trail, and recessive allele t expresses short tail.

<u>Genotypes Phenotypes</u>

EETT, EeTT, EETt, EeTt Square eyes and Long tail

eeTT, eeTt Round eyes and Long tail

EEtt, Eett Square eyes and Short tail

eett Rounf eyes and short tail.

<em>1. An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype?</em>

The heterozygous individual is E/e ; T/t, expressing square eyes and a long tail.

<em>2. Two individuals, who are both heterozygous for eye shape and tail size, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring?</em>

Cross: between two heterozygous individuals

Parentals) EeTt x EeTt

Gametes) ET, Et, eT, et

ET, Et, eT, et

Punnett square) . ET Et eT et

ET EETT EETt EeTT EeTt

Et EETt EEtt EeTt Eett

eT EeTT EeTt eeTT eeTt

et EeTt Eett eeTt eett

F1) Genotype:

1/16 EETT
2/16 EETt
1/16 EEtt
2/16 EeTT
4/16 EeTt ⇒ 1/4 EeTt
2/16 Eett
1/16 eeTT
2/16 eeTt
1/16 eett

Phenotype

9/16 E-T-, Square eyes and Long tails
3/16 E-tt, Square eyes and short tails
3/16 eeT-, Round eyes and Long tails
1/16 eett, round eyes and short tail

Phenotypic ratio 9:3:3:1

<em>3. From the mating described in question ABOVE, what proportion of ALL of the offspring in will be heterozygous for both traits?</em>

4/16 = 1/4 = 25% of the progeny are expected to be heterozygous for both traits, EeTt.

The structure of a substrate P strongly resembles substrate Q. In an experiment, By mistake P was used instead of Q as a substra

Dvinal [7]

<h3><u>Answer;</u></h3>

C) P and Q have similar binding properties

<h3><u>Explanation;</u></h3>

<u><em>Enzymes are biological catalysts that speeds up chemical reactions. Substrates are substances that are acted on by an enzyme to form a product.</em></u>
<u><em>An enzyme catalyzed reaction occurs when the substrate binds to the active site of an enzyme to form and enzyme-substrate complex. </em></u>
<em><u>Substrate P and Q are structurally similar which means they are in a position of binding and fitting in the active site of an enzyme. The strong structural similarity means that the binding properties of these two different substrates may be similar. </u></em>
<em><u>Formation of similar products or results when acted upon by an enzyme mean they are similar in terms of their binding properties, and thus the production of similar product.</u></em>

Which organisms have the fewest similarities? Explain why these organisms still qualify as living things despite sharing few cha

VladimirAG [237]

Plants have the fewest similarities with the other two groups of organisms.

<h3>Plants vs animals</h3>

Plants generally comprise all living organisms that have chlorophyll and are able to manufacture their own foods by photosynthesis.

Animals, on the other hand, are living organisms that cannot manufacture their foods and are mobile. Animals are either vertebrates or invertebrates.

Plants qualify as living organisms because they are able to feed, excrete, reproduce, grow, respond to stimuli, die, and carry out other basic characteristics of living organisms.

What genetic variation has occurred in the picture below where a black bunny and a white bunny have an offspring that shows both

Softa [21]

<h2>Answer:</h2>

The correct answer is B which is codominance.

<h3>Explanation:</h3>

One allele of a gene for a trait can be dominant or recessive according to the simple genetic phenomenon.
But there are some exceptions Like both allele can express them dominantly producing an offspring having both forms of that trait.
While in incomplete dominance, dominant allele is unable to expresses itself completely and a phenotype between dominant and recessive trait is produced.
Hence in the problem, offspring have both colors of fur from two parents, so it is codominance.
