If Two People Who Are Both Heterozygous For The Trait Of A Bent Pinky Finger Have A Child, What Are The

Answers

Answer 1

genotypes is 1:2:1 & phenotypes is 3:1

l hope this helps you

Answer 2

Answer:

When two people heterozygous for the trait of a bent pinky finger have a child, the possible genotypes CC, Cc and cc -in a ratio of 1:2:1- being the phenotypes bent pinkies: straight pinkies in a ratio of 3:1.

Explanation:

Bent pinky finger is due to a condition called Camptodactyly, characterized by sustained bending of a finger due to a deformity in an interphalangeal joint. Pinky finger camptodactyly is a trait that is inherited in an autosomal dominant pattern.

With camptodactyly (bent pinky finger) C Without camptodacilia (straight pinky finger) c

The parental generation is made up of two heterozygous individuals with bent pinky fingers:

♂ Cc

♀ Cc

The offspring of this hybrid cross, according to Mendelian heritage, can be seen in this Punnett Square:

Alleles       C     c

C             CC   Cc

c             Cc    cc

According to this the offspring will have:

Genotypes:

CC: 25%

Cc: 50%.

cc: 25%

Phenotypes:

Bent pinky finger: 75%

Straight pinky finger: 25%

Yeast cells, plant cells, and mammal cells all share many similarities in cell signaling. This provides evidence that:________

a. cell-signaling mechanisms are only found in organisms that use methods of sexual reproduction
b. intercellular communication evolved as a way for multicellular organisms to coordinate cell functions
c. eukaryotic cells use signal transduction pathways while prokaryotic cells use a more primitive form of signaling
d. signal transduction pathways appeared in cells before the evolution of multicellular organisms

Answers

Answer:

D

Explanation:

Yeast cells, plant cells, and mammal cells all share many similarities in cell signaling. This provides evidence that signal transduction pathways appeared in cells before the evolution of multicellular organisms. Thus, the correct option for this question is D.

What is cell signaling?

Cell signaling may be defined as a process through which a cell of an organism may respond to substances outside the cell through signaling molecules found on the surface of and inside the cell.

This biological process of cell signaling is ultimately required in order to accomplish all sorts of metabolic activities that are essential for the survival of living organisms, no matter whether they are prokaryotic or eukaryotic, unicellular or multicellular.

Therefore, the correct option for this question is D.

A group of people have white blood cell (WBC) counts that are from 4,500 to 10,000 WBC/ml. All cell count values in that range are equally abundant in the population. What is the mean WBC count in the population?

Answers

Answer:

7250 WBC/ml

Explanation:

The mean of any value is the average of a certain amount of given values. When this is taken into cognizance, to get the mean White Blood Cell count of the population, given two ranges, is to add and divide both together. This gives us

10,000 + 4,500 = 14,500 WBC/ml

The mean then is

14,500 / 2 = 7250 WBC/ml

Therefore, the mean White Blood Cell count in the population is 7250 WBC/ml



Muscular dystrophy is a neuromuscular disease that weakens a person's muscles. Which main body systems would be involved in this disease? (1 point)

Answers

Answer:

nervous, muscular, and vascular

Explanation:  

Muscular dystrophy (MD) is a group of inherited genetic conditions that cause progressive weakness and the loss of muscle mass. MD is caused by mutations in genes responsible for muscle function. MD not only leads to problems in the muscular system but also may cause disorders of the central nervous system and the circulatory system (especially the heart). For example, Becker muscular dystrophy is a condition associated with arrhythmias and cardiomyopathies. Moreover, MD may lead to vision and speech problems, and result in irreversible structural brain changes.

Answers

Answer:

Because salt is an agent that attracts and draws out water, the surrounding salt water draws water from inside the fish so they must constantly drink water to replace the lost water in their system.

What are the hemispheres of earth?

Any circle drawn around the Earth divides it into two equal halves called hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western.

Hemisphere comes from the Greek, and combines the prefix hemi-, for "half," with sphere, or "perfectly round ball." We talk about the earth as divided at the equator into the northern and southern hemispheres.

It is important because it brings about differences in the climates of the Northern and Southern hemisphere because of the Earth's seasonal tilt towards and away from the sun.

Identify all statements that accurately describe the structure of the pyruvate dehydrogenase (PDH) complex.A. A regulatory kinase and phosphatase are part of the mammalian PDH complex. B. Several copies each fo E1 and E3 surround E2. C. E2 contains three domains. D. The complex contains multiplex is made up of several copies of E1.

Answers

Answer: Options A, B ,C and E are correct

Explanation:

The structure of pyruvate dehydrogenase complex comprises if three enzymes E1, E2 and E3 which convert pyruvate to acetyl CoA. The three enzymes are have several copies.

Within the PDH complex, the E2 subunit forms the structural unit, contain three domains and are surrounded by E1 and E3. The E 2 accepts acetyl groups from E1 and transmit the group to coenzyme A. The decarboxylation of pyruvate and its conversion to acetyl-CoA by the PDH complex comes first before glucose carbon enter into the tricarboxylic acid (TCA) cycle. This process is important to the aerobic oxidation of glucose .

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles of the leg.

Answers

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.

The specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.

The function the eyes performs requires more precise locomotion control than the movement of the limbs require.

For an eye movement to be made, an action potential must be transmitted which makes the sarcomeres of the elastic fibers and z-lines to unit thereby producing movement of the eye. This movement are usually done with almost perfect preciseness.

This is why there are more alpha motor neurons that control eye movement than we have in postural muscles of the leg.

In summary, the specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.
