A pedigree involving a human disease that is inherited in a simple Mendelian manner, and it is only autosomal dominant (complete penetrance) that is present in the third option.

The pedigree explains the rate of passing of the genetic diseases from one generation to the next, and here the pedigree is an autosomal dominant pedigree because a parent can be either purebred dominant or heterozygous for the trait and produce both diseased and normal offspring. It cannot be recessive because III-8 and III-9 parents do not produce all recessive offspring.

Hence, the pedigree involves a human disease that is inherited in a simple Mendelian manner, and it is only autosomal dominant (complete penetrance) that is present in the third option.

The food of come from autotrophic plant to animal through food chain. The energy cycles between the air and soil and plants, animals, and microbes occur by food web.

A food web is defined as the cyclical event of energy transfer among different trophic level of organism.

The major components are primary producers, primary consumers, secondary consumers, tertiary consumers, quaternary consumers

Primary producers are the green autotrophic plants and capture some of the solar energy  and convert it into chemical energy by photosynthesis.

The net primary productivity (NPP) of energy is defined as the rate of photosynthesis minus the rate of respiration of plants.

Primary consumers or herbivores feed on producers constitute  the second trophic level of the food web.

in third tropic level, Secondary consumers eat primary consumers where as  tertiary consumers, quaternary consumers or predators, carnivores or omnivores, which are both plant- and animal-eaters, such as humans.

Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.

Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.

Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.

Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.

The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.

Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.

This shows that Carlton has an impaired absolute threshold.

He could not detect the smallest quantity of a stimulus to differentiate between the smells.

Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.

This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.

Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

Answer:

Identical twins share the exact same DNA while fraternal twins do not.

Explanation:

Mitosis is the type of cell division that results in 2 individual cells that have the exact genetic material.

Meiosis is the division of reproductive cells, eggs and sperms, which results in new cells with half the amount of genetic material and that makes them unique.

Identical twins are twins developed from a single egg that has been fertilized with a single sperm, meaning they have the same DNA.

Fraternal twins are twins from two different eggs that have been fertilized by two different sperms and grow in the womb at the same time with no additional cell division. So they have different DNA's.

I hope this answer helps.

The formation of fraternal twins takes place when the female generates two eggs and identical twins takes place when the female generates one egg and the zygote divides into two spontaneously.  

• In identical twins case, the zygote goes through cleavage, that is, cell division by mitosis, when embryo is at the stage of two cell.  

• The separation of two blastomeres may take place and then each act as an independent zygote.  

• This each dissociated blastomere give rise to a novel independent individual.  

• The production of both the organisms takes place due to mitosis, thus, both would possess identical genetic makeup and are known as identical twins.  

• Identical twins would be either males or would be either females.  

• In case of fraternal twins, the female generates more than one eggs. And all the eggs get fertilized independently by the sperm.  

• Thus, formation of two or more zygotes takes place, and each zygote give rise to new offspring.  

• These offsprings possess distinct genetic combinations, and such offspring are known as fraternal twins.  

• They are produced sexually, and fraternal twins can possess different genders as they do not possess similar genetic recombination.  

Thus, identical twins is formed from one egg and the zygote gets divide into two, while fraternal twins formation takes place when two eggs are generated by the female.

Explanation:

The four major stages of bone repair after a fracture are:

Hematoma formation: Immediately after a bone is fractured, the body forms a hematoma, which is a blood clot that stops the bleeding and creates a framework for the subsequent healing process.

Fibrocartilaginous callus formation: Within a few days of the fracture, new blood vessels and cells invade the hematoma, and fibroblasts start producing collagen fibers, forming a soft callus. As the fibroblasts differentiate into chondroblasts, the callus becomes more cartilaginous, creating a firmer structure. This process takes several weeks and is known as fibrocartilaginous callus formation.

Bony callus formation: Osteoblasts begin producing new bone tissue in the cartilaginous callus, transforming it into a bony callus. This process is called bony callus formation and can take several months. The bony callus gradually replaces the cartilaginous callus, resulting in a stronger and more rigid structure.

Remodeling: Over time, the newly formed bone undergoes a remodeling process where the excess bone is resorbed, and the bone is reshaped to resemble its original structure. This process can take up to several years.

It is beneficial to start the healing process with fibrocartilage rather than producing new mineralized bone immediately because the fibrocartilage provides a soft and flexible framework that helps stabilize the fracture site and allows for movement during the early stages of healing. The cartilage also provides a scaffold for the subsequent bone formation by osteoblasts. The gradual transformation of the cartilage into bone allows for a gradual increase in strength at the fracture site and reduces the risk of re-injury during the healing process. If mineralized bone were produced immediately, it would be too rigid and brittle, increasing the risk of further damage to the bone and surrounding tissue. Additionally, the production of new bone tissue requires a significant amount of energy, and starting with fibrocartilage helps conserve energy and optimize the healing process.
