Answer:

B. the body's internal environment

Explanation:

Homeostasis is defined as the process of maintaining the internal environment of the body.

All the systems work together to maintain homeostasis. The nervous and endocrine systems are two important system that helps in maintaining homeostasis.

The nervous and endocrine systems are linked with hypothalamus that controls the internal environment of the body by releasing and inhibiting hormones. These hormones keep pH,  temperature,  and other internal conditions stable that support homeostasis.

Hence, the correct answer is "B. the body's internal environment".

Answer:

The phase of mitosis where chromatids are formed is Metaphase

Answer:

During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.

The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.

During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive basically depends on the inhalation because of elastic recoil that causes a decrease in volume.

During this, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle whereas quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.

Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

Thus, in quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive basically depends on the inhalation because of elastic recoil that causes a decrease in volume.

Scientists have determined that Earth and the moon most likely could not have formed together when the solar system was created. If they had, the moon would have a large iron core like Earth's, but it instead has a small iron core.

Answer:

D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species

Explanation:

During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.

The option that best describes how independent assortment results is D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species

Independent assortment is a phenomenon that occurs during meiosis, which is the process of cell division that produces gametes (sex cells). During meiosis, the chromosomes are randomly sorted into the gametes. This means that the alleles (different forms of a gene) on different chromosomes can be inherited together or separately.

This random assortment of alleles can lead to new combinations of traits, which can be beneficial or harmful to a species.

Answer:

The correct option is a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.

Explanation:

Available data:

              Males: 39 red eyes; 11 sepia eyes

77% of the total progeny has red eyes and 23% has sepia eyes.

Among females, 75% is red-eyed, and 25% is sepia-eyed

Among males, 78% is red-eyed, and 22% is sepia-eyed.

The general phenotypic ratio is 3:1

If the eye-color gene was sex-linked, the phenotypic ratios would be different. There would be a higher proportion of red-eyed females than red-eyed males. Females would only express red eyes, while males would express red and sepia eyes. This is

Cross:         X⁺X⁻   x    X⁺Y        (Note: The symbol + represents the allele R

Phenotype: red-eyed both                    and the symbol  - the allele r)                  

Gametes) X⁺       X⁻     X⁺    Y

Punnett square)    X⁺         X⁻

                      X⁺   X⁺X⁺     X⁺X⁻

                       Y    X⁺Y       X⁻Y

F2) 3/4 of the whole progeny would be red-eyed

     1/4 of the whole progeny would be sepia-eyed

  BUT

     Females: 100% red-eyed

     Males: 50% red-eyed and 50% sepia-eyed

These proportions are not coincident with the exposed real proportions

So,

c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.

If this gene was sex-linked, Males and females would not have similar phenotype ratios. This is FALSE.

d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.

If this gene was sex-linked, Males would display both phenotypes, but females would only be red-eyed. This is also FALSE.

According to this, we can assume that this is an autosomal gene. If this is true, then

Cross:   Rr XX    x    Rr XY

Gametes) RX, RX, rX, rX

                RX, RY, rX, rY

Punnett square:

              RX       RX       rX       rX

RX      RRXX    RRXX   RrXX   RrXX

rX       RrXX      RrXX    rrXX    rrXX

RY      RRXY     RRXY   RrXY   RrXY

rY       RrXY      RrXY    rrXY    rrXY

F2)  From the whole progeny

       Phenotypic ratio 3:1

       Among females

        Phenotypic ratio 3:1

      Among males

       Phenotypic ratio 3:1

The phenotypic ratio in all cases are 3:1.

b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.

Both males and females exhibit sepia eyes in equal proportions. This is FALSE

a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.

Males and females do have similar phenotype proportions of red eyes and sepia eyes. This is TRUE

Answer:

See the answer below

Explanation:

Normal height - H

Short height - h

Heterozygous - Hh

A cross involving heterozygotes would be Hh x Hh

         Hh    x    Hh

      HH   Hh   Hh   hh

Since H is dominant over h;

HH and Hh would produce normal height phenotypes.

hh will produce a short height phenotype.

Thus;

Probability of normal height phenotype resulting from the cross = 3/4 or 75%

Probability of short height phenotype resulting from the cross = 1/4 or 25%

Answer:caffe

Explanation:

Answer:

When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.
