Which is a type of heat transfer that causes the air at the top floor of a building to be hotter than the air at the bottom floor of a building?

conduction
convection
radiation
reflection​

Answers

Answer 1

Answer:

I belive it is Convection

Explanation:

It is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

The female reproductive system includes the glands and organs that produce the female gamete, the egg. The highlighted part in the diagram stores eggs. Thus, option C is correct.

What are the parts of the female reproductive system?

The female reproductive system has various organs like ovaries, fallopian tubes, vagina, uterus, accessory, and other external organs. They are involved in the production and storage of eggs or the ovum.

The ovaries are the main organs that are two in number and oval-shaped structures, located on either side of the uterus, and produce ovum and hormones, estrogen and progesterone.

During the menstrual cycle, one of the ovaries releases the ovum in the fallopian tubes that may get fertilized or get shaded with the blood and tissues. The egg is produced through the process of oogenesis in the ovaries.

Therefore, the highlighted part is the ovary that stores the egg.

Answers

Answer:

RR is hom0zygous dominant and will Red

Rr is heterosygous and will also be red

rr is hom0zygous recessive and will be white

Explanation:

The filling of the chart with respect to the genotype given is as follows:

RR (homozygous dominant) gives Red eye color in fruit flies. Rr (heterozygous) will also deliver red eye color in fruit flies.rr (homozygous recessive) gives white eye color in fruit flies.

What is meant by Genotype?

Genotype may be defined as the ultimate combination of alleles of those genes which are selected for specific study in order to deliver some sort of genetic information.

As it is an organism is its complete set of genetic material. These can also be utilized in order to refer to the alleles or variants an individual carries in a particular gene or genetic location.

In fruit flies, red eye color is dominant over white eye color. So, when red eyed-colored (RR) flies are crossed with white-eyed colored flies (rr), they produce offspring with the genotype Rr and phenotype of red-eye color. This all deals with the law of dominance.

Therefore, the filling of the chart with respect to the genotype given is well described above.

Thus, the correct option for this question is D.

What is Star?

Star may be characterized as a huge ball of blazing gases in space that is typically observed from the earth as a point of light in the sky at night. It is a type of astronomical object.

As we relate the brightness of a star with respect to the distance, it is found that the closer a star is, the brighter it will appear in the sky. So, a Star Y is the brightest, it will closer to the earth. With this sense of knowledge, options 1 and 2 are eliminated.

Star X is larger than star Z, so, star Z is found to be closer than Star X. With this, option 3 is also eliminated.

What happens after activation of T cells

Answers

Answer:

Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.

Explanation:

Helper T cells become activated when they are presented with peptide antigens by MHC class II molecules, which are expressed on the surface of antigen-presenting cells (APCs). Once activated, they divide rapidly and secrete cytokines that regulate or assist the immune response.

Consider one such cell where the magnitude of the potential difference is 40 mV, and the inner surface of the membrane is at a higher potential than the outer surface. A sodium ion (Na ) is initially just outside the cell membrane (initially at rest). How much work (in J) is required for a cell to absorb the ion, so that it moves from the exterior of the cell to the interior

Answers

Answer: W = 6.4x10⁻²¹J

Explanation: Work is the energy transferred to or from an object due to the application of a force along a displacement.

The ion Na is gaining energy to move from a lower potential to a higher one.

For this to happen, the work done is calculated as

[tex]W=q.\Delta V[/tex]

in which

W is work in Joules (J)

q is charge in Coulomb (C)

[tex]\Delta V[/tex] is potential difference in Volts (V)

The ion Na has one positive charge. In coulombs, the charge is

q = 1.6x10⁻¹⁹C

The potential difference in Volts is

[tex]\Delta V[/tex] = 40x10⁻³ or 4x10⁻²V

Calculating

[tex]W=q.\Delta V[/tex]

W = 1.6x10⁻¹⁹. 4x10⁻²

W = 6.4 x 10⁻²¹ J

The work done to move an ion of sodium from the exterior to the interior is 6.4 x 10⁻²¹ J.

Why does a fever become dangerous to body functions if it continues to rise?
A. Dehydration will occur
B. Osmosis may be affected due to lack of water
C. A fever breaking is more dangerous than the fever itself
D. Proteins become denatured and are unable to complete their jobs

Answers

b osmosis may be affected due to lack of water

Fever has been defined as the rise in the temperature of the body. The rise in fever is a dangerous process as lack of water causes dehydration in the body. Thus, option A is correct.

What is dehydration?

Dehydration is the loss of water and body fluid than the intake of the fluid amount. The high-temperature condition of the body causes the loss of water from the body that gets evaporated from the skin cells.

When a person is suffering from fever the body fluid and electrolytes are lost by vomiting, tears, sweat, diarrhea, and urine. Dehydration can be detected by thirst, dry mouth, dizziness, etc.

Too much heat in the body during fevers results in the loss of water from the body that is more because the fluid intake gets reduced and the body becomes deficient in electrolytes and fluids.

It is a serious problem that should be dealt with so that the cells and tissues of the body can restore the water balance that is crucial for various activities and functions.

Therefore, option A. increase in the temperature in fever causes dehydration.
