Answer:

The correct answer is - in the sickle-cell hemoglobin is the replacement of glutamic acid with valine in the β-globin amino acid chain.

Explanation:

Sickle cell anemia has a mutant gene in which that produces has valine amino acid instead of glutamate in the hemoglobin protein. In the given question the structure of the protein has only one difference that is the replacement of the glutamic acid in normal hemoglobin to valine in the β-globin amino acid chain in the mutant protein.

Valine 6 (beta chain) binds to a different hydrophobic patch (on the alpha chain and causes the disease in sickle cell anemia cases.

Answer:

50%

Explanation:

Draw a Punnet square to determine the percentage of offspring that are tall.

The green and blue highlighted columns and rows represents the genotype of the parents. To fill in the genotype of the offspring, write down the letter (T/t) of the parent allele from that row and column the offspring belongs to. By convention, the T is written before t. (The genotype of a tall offspring is written as Tt not tT)

Since the T allele is dominant, as long as the offspring has one T, the offspring is tall. The t allele is recessive, thus two ts (tt) is needed for the short trait to be expressed.

From the Punnet square, the result is 2 offsprings that are tall and 2 offsprings that are short.

Required percentage

[tex] = \frac{2}{4} \times 100\% \\ = \frac{1}{2} \times 100\% \\ = 50\%[/tex]

Explanation:

Answer:

Cyclosis- streaming of cytoplasm within a living cell without deformation of the external cell membrane. In some plant cells there is a rapid rotatory cytoplasmic movement, which is limited to the peripheral parts of the cell next to the cell wall; chloroplasts and granules move in this stream.

Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell. Plasmolysis is one of the results of osmosis and occurs very rarely in nature, but it happens in some extreme conditions.

Explanation:

If the light converges before reaching the back of the eye, this means that the person is nearsighted and has trouble seeing objects that are far away. To correct nearsightedness, the lenses in the person's glasses would need to divert the light before it entered the eye. Therefore, the glasses would have concave lenses.

If the light converges before reaching the back of the eye, it means that the person is suffering from a refractive error known as myopia, or nearsightedness. To correct myopia, the lenses in the person's glasses should be concave, which means they are thicker at the edges and thinner in the center. Concave lenses are designed to diverge light rays, which helps shift the focal point of light farther back so that it falls directly on the retina. By doing so, the glasses help the eyes see distant objects more clearly.

Hence, if the light converges before reaching the back of the eye, this means that the person is nearsighted and has trouble seeing objects that are far away. To correct nearsightedness, the lenses in the person's glasses would need to divert the light before it entered the eye. Therefore, the glasses would have concave lenses.

Answer:

Most thunderstorms form by a cycle that has three stages: the cumulus stage, mature stage, and dissipating stage.

Cumulus Stage

The sun heats the Earth's surface during the day. The heat on the surface and warms the air around it. Since warm air is lighter than cool air, it starts to rise (known as an updraft). If the air is moist, then the warm air condenses into a cumulus cloud. The cloud will continue to grow as long as warm air below it continues to rise.

Mature Stage

When the cumulus cloud becomes very large, the water in it becomes large and heavy. Raindrops start to fall through the cloud when the rising air can no longer hold them up. Meanwhile, cool dry air starts to enter the cloud. Because cool air is heavier than warm air, it starts to descend in the cloud (known as a downdraft). The downdraft pulls the heavy water downward, making rain.

This cloud has become a cumulonimbus cloud because it has an updraft, a downdraft, and rain. Thunder and lightning start to occur, as well as heavy rain. The cumulonimbus is now a thunderstorm cell.

Dissipating Stage

After about 30 minutes, the thunderstorm begins to dissipate. This occurs when the downdrafts in the cloud begins to dominate over the updraft. Since warm moist air can no longer rise, cloud droplets can no longer form. The storm dies out with light rain as the cloud disappears from bottom to top.

The whole process takes about one hour for an ordinary thunderstorm. Supercell thunderstorms are much larger, more powerful, and last for several hours.

Answer:

The water passes through the filter paper.

Explanation:

Since sugar is able to dissolve completely in water, sugar solution is a homogenous mixture and thus its composition is uniform throughout and is able to be filtered out without separating its components.

Answer:

I believe it's a physical change?

Explanation:

Mixing sand and gravel is considered a physical change as it only affects the physical properties, such as appearance and distribution, without altering the chemical nature of the substances involved.

A physical change is a transformation that does not alter the chemical composition or identity of a substance. In the case of mixing sand and gravel, both substances retain their individual properties and characteristics even when they are combined.

The sand particles and gravel particles remain unchanged in terms of their chemical composition.

The mixing process involves the physical interaction of sand and gravel particles, resulting in a uniform distribution of the two components. This change in arrangement does not involve any chemical reactions or the formation of new substances.

The sand and gravel can be easily separated by physical means, such as filtration or sieving, without undergoing any chemical transformations.

Therefore, mixing sand and gravel is considered a physical change as it only affects the physical properties, such as appearance and distribution, without altering the chemical nature of the substances involved.

Answer:

Explanation:

Pure water is an hypotonic solution that allows for diffusion of water into the cell and the cell will begin to swell.

The movement of water into the cell will make the cell swell but if water is moving outside the cell will collapse and shrink.

The turgor pressure is usually found withing the cell it ensures the movement of solutes when water is taken into the cell, the turgor pressure will increase. When water is taken out of the cell, the pressure will reduce.

Answer:

In general, your body fights disease by keeping things out of your body that are foreign. Your primary defense against pathogenic germs are physical barriers like your skin. You also produce pathogen-destroying chemicals, like lysozyme, found on parts of your body without skin, including your tears and mucus membranes. In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader. The immune system has a vital role: It protects your body from harmful substances, germs and cell changes that could make you ill. It is made up of various organs, cells and proteins.

Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. These cells are then primed to resist an infection with the invading virus. Cytokines such as interferons activate anti-viral genes in the infected and neighbouring cells.

Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread, or be transmitted, by several routes.

The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).

If pathogens do manage to enter the body, the body's second line of defense attacks them. The second line of defense includes inflammation, phagocytosis, and fever.
