Answer: Pure line plant

Explanation:

Pure line plants are those plants that are used for breeding and selecting organisms with a desire trait to a number of generations until the wanted trait is established. Mendel had chosen pea plant for his experiments and that was a pure line species. It was bred to many generations so as to obtain the desired trait in successive generation. The plants were utilized to study the laws of inheritance. Also it was noticed that one trait being recessive in one generation will be expressive in other generation.

One of the genetic diseases known as sickle cell disease is sickle cell anemia. Red blood cells, which deliver oxygen to every region of the body, are affected in terms of structure.

Red blood cells can flow through blood veins with ease. Red blood cells with sickle or crescent shapes are characteristic of sickle cell anemia.

Additionally, these sickle cells develop a hard and sticky coating that can hinder or delay blood flow.

Most persons with sickle cell anemia are incurable. Treatments can reduce suffering and aid in avoiding disease-related consequences.

Therefore, One of the genetic diseases known as sickle cell disease is sickle cell anemia. Red blood cells, which deliver oxygen to every region of the body, are affected in terms of structure.

When red cattle breed with red cattle, the resultant offspring show both red and white fur, resulting in a mixed coat pattern called "roan."

The roan pattern, normally in Shorthorn cattle, is inherited as a heterozygous genotype. Roaming is usually the intermixing of two dissimilar colored hairs - black and white make a blue roan while red and white make a red roan.

The roan coat color in livestock species is distinguished by a mixture of white and tint hair in cattle, If it is a breed that has the roan color pattern, like a Shorthorn, then yes it can be pure-blooded. Or it can be a cross-breed with the roan color pattern. Roan is a color, not a breed.

So we can conclude that Roan" mentions a horse coat color pattern characterized by a mixture of colors.

Mendel's tests on the pea plant are still relevant today since they demonstrate how traits are passed down through generations, hence option D is correct.

The pea experiment is frequently used in classrooms because peas have distinguishable qualities and it is relatively straightforward to analyze how these traits are inherited.

When a person possesses a dominant characteristic and is heterozygous for that trait, the descendants of that person might also possess a recessive trait.

Therefore, It helps show the transmission of traits from parents to offspring.

Answer:

B. Wind

Explanation:

Because nature constantly replenishes the wind, we can continue to harness its power without worrying about running out of it.

Answer:

The correct answer is "40.6%". A further explanation is provided below.

Explanation:

The given values are:

The proportion of people with resistance is,

aa = 8%

or,

    = 0.08 (q²)

q² = 0.08

q   = √0.08

    = 0.28284

Now,

⇒ [tex]p+q=1[/tex]

⇒       [tex]p=1-q[/tex]

             [tex]=1-0.28284[/tex]

             [tex]=0.717157[/tex]

hence,

For the HIV resistant allele, the proportion of people will be:

= [tex]Aa[/tex]

= [tex]2pq[/tex]

On substituting the values, we get

= [tex]2\times 0.71715\times 0.28284[/tex]

= [tex]0.4056[/tex]

= [tex]40.6[/tex] (%)

The proportion of the population with the carrier of HIV-resistant allele is 40.56%.

Hardy Weinberg equilibrium is the relationship between the variation from one generation to the next. The equation for the relationship can be given as:

[tex]p^2+2pq+q^2=1[/tex]

Where the proportion of dominant alleles is p².

The proportion of recessive alleles is q².

The proportion with the caries are 2pq.

The given recessive allele proportion in the population is 0.08. The proportion of dominant alleles can be given as:

[tex]q^2=0.08\\q=0.2828[/tex]

The dominant alleles can be given as:

[tex]p+q=1\\p+0.28284=1\\p=0.717157[/tex]

The carriers in the population can be given as:

[tex]\text{Carriers}=2pq\\\text{Carriers}=2\;\times\;0.717157\;\times\;0.2828\\\text{Carriers}=0.4056\\\text{Carriers}=40.56\%[/tex]

Thus, the carriers for the HIV gene in the population are 40.56%.

Intercalated disc also called gap junctions are structural formations that are located between the myocardial cells of the heart. They help to bond or connect cardiac cells fibers together. They also help in cell to cell communications and propagate action potential. They serve to transfer signals between cells.

All of an organism's characteristics are inheritable which evolves over millions of years. An example of this is the modern day horse's foot.

This is referred to as the change in the heritable characteristics of biological populations over successive generations.

All an organism's characteristics can be inherited and evolves over a period of time as a result of the changing environmental conditions which helps them to adjust thereby increasing their chances of survival hence preventing extinction of species.

For example, over millions of years of evolution, many horses lost their side toes and developed a single hoof as a result of them needing to move at faster speeds to evade predators.

Answer:

DNA

Explanation:

About 80% of the population can determine their blood type from saliva, tears, sweat or milk. These are known as secretors, and they refer to the fact that antigens present in the blood can also be found in bodily fluids like saliva.

Your immune system uses antigens as markers to determine whether or not something in your body is hazardous. Viruses, bacteria, cancers, and healthy bodily cells all include antigens. Antigen testing is carried out to identify viral infections, keep an eye on specific illnesses, screen for them, and ascertain a donor's compatibility with a transplant.

The term "secretor status" describes whether water-soluble ABO blood group antigens are present or absent in a person's body fluids, including saliva, tears, breast milk, urine, and semen. People are classified as secretors or non-secretors depending on whether they secrete certain antigens in their body fluids.

Explanation:

Okay so, genes come in different varieties; which are called allele. somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. BUT, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

During meiosis I, chromosomal pairs randomly align along the metaphase plate. Each chromosome pair member carries one allele for each gene. Every gene combination shows up in the offspring.

Chance determines which of the 23 homologous pairs of both parents' chromosomes are inherited. The possible combinations of 23 chromosomal pairs total 8,324,608. As a result, the chromosomal combinations of two gametes are almost never identical.

Actually, each parent has two distinct gene pools. Additionally, only half of each parent's DNA is passed on to their offspring. and that the randomness of the portion that is passed down. All of these factors work together to guarantee that every child has a distinct collection of genes.

Answer:

Exchange of gases takes place at alveoli sacs of lungs, which are equipped with capillary vessels or bed.

Explanation:

On inspiration or taking air through nostrils, surrounding air enters the lungs and it reaches air sacs or alveoli. Here, the outside air will have more amount of oxygen when compared with oxygen in blood at that site. Hemoglobin in the blood have high bonding capability to oxygen, so it captures oxygen and takes it to heart for pumping into other parts of the body. Likewise, the circulations continues from lungs to heart > hear to body parts > body parts to heart > heart to lungs for purification.

What are Air Masses:  They large volumes of air that have generally the same temperature and pressure.

How they work: One is heated by an electrical current, the other is not. As air flows across the heated wire, it cools down.

Example of an Air Mass: The air masses in and around North America include the continental arctic, maritime polar, maritime tropical, continental tropical, and continental polar air masses. Air is not the same everywhere.

Fact: Unstable air masses have different temperatures and pressures.

How they are formed: An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.

*** The Earth's major air masses originate in polar or subtropical latitudes.
