Answer:

(i) An allele is a variant of a gene, can either be short or tall.

Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.

(ii) David's eyes are Brown

(iii) Sarah's eyes are blue

(iv) David - B, b

Sarah - b, b

(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.

(vi) The chance for blue eyes is 50% (or 1:1 ratio)

How many atp equivalents are consumed in the conversion of each of the following to a glucosyl residue in glycogen?

Nina [5.8K]

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

Dihydroxyacetone phosphate - 1

Fructose-1,6-bisphosphate - 1

Pyruvate - 13

G-6-P - 1

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

1) Dihydroxyacetone phosphate = 1

G1P + GTP --> UDPG + PPi two P is equivalent to 2 ATP --->2 ADP + Pi) Therefore, two ATP equivalents - but UDP is the product and only one P needed

2 DHAP --> F1,6-BP -->F6P --> G6P -->G1P -->UDPG --> glucosyl residue

2) Fructose 1,6-bisphosphate = 1

3) Pyruvate = 13

2 pyr + 2 ATP --> 2 OAA

2 OAA + 2 GTP --> 2 PEP

2 PEP --> 2 2PG --> 2 3PG

2 3PG + 2 ATP --> 2 1,3 BPG

2 1,3 BPG + 2 NADH --> 2 G3P

2 NADH = 6 ATP

2 G3P --> DHP + G3P --> FDP -- > F6P + P

F6P --> G6P --> G1P

G1P + UTP --> UDPG + PP

4) Glucose-6-phosphate = 1

G6P -->G1P G1P + UTP --> UDP-GLC + 2 Pi

UDP-Glc + glycogen --> glycogen+ 1 Glc

What is the major difference between bacterial chromosomes and eukaryotic chromosomes?.

Sphinxa [80]

The major difference between bacterial chromosomes and eukaryotic chromosomes is that bacteria have a single circular chromosome whereas eukaryotes have several linear chromosomes.

Eukaryotic chromosomes are present within the nucleus while prokaryotic chromosomes are found in the nucleoid (a region of the cytoplasm). The nucleoid does not have a membrane.

In eukaryotic chromosomes, DNA is wrapped around histone proteins, which is further compacted by supercoiling and folding. However, in prokaryotic chromosomes, DNA is supercoiled and held together by nucleoid-associated proteins.

Prokaryotic chromosome is very simple in comparison to the eukaryotic one. Prokaryotic chromosome lack telomeres and centromeres sequences which is found in the eukaryotic chromosomes.

In some cases, inflammation of cranial nerves accompanies acute labyrinthitis. Which cranial nerve is most likely to be affected

Roman55 [17]

The cranial nerve most likely to be affected hat is evidenced by acute labyrinthitis is the EIGHTH Cranial Nerve named Vestibulocochlear.

Vestibulocochlear nerve dysfunction can cause hearing loss, vertigo, or tinnitus. The dysfunction is a result of the damage in either the cochlear or vestibular portion of the eighth cranial nerve. Damage is between the inner ear and its entry into the brainstem at the pontomedullary junction.

Vestibular neuritis is also identified as labyrinthitis, vestibular neuronitis, and acute peripheral vestibulopathy.

One way to increase the number of organisms in an endangered species is to let the few remaining individuals o

ICE Princess25 [194]

Answer:

Reduce genetic diversity

Explanation:

Genetic diversity is an extremely important factor when it comes to evolution. The more diversity and variation there is within a population, the more chances a species has of surviving.

In the case of inbreeding, organisms that are related are selected to mate. This has extremely negative effects on the species such as bad health and infertility issues. In addition, because they all share the same alleles, it results in a decrease in genetic diversity, augmenting the chances of the species to disappear.

This occurs because if, for example, there is an organism that possesses a capability to resist extreme weather conditions and another that does not have this trait, there are still chances to survive, whereas if they are all the same and none of them possess this capability, the probability of this species to go extinct is higher.
