Explanation:
Is mixing sand a gravel a physical or chemical change?
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.

In pea plants, tall (T) is dominant to short (t). A plant with genotype Tt is crossed with a plant with type tt. What percentage of their offspring will be tall?
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]
Compare and contrast innate immunity and adaptive immunity.
Answer: the difference between innate and adaptive immunity is that innate immunity is a fast immune response that provides the first line of immunological defense against infections while adaptive immunity is a slow immune response mediated by the T and B lymphocytes.

Suppose the light converged before reaching the back of the eye.
What lenses would be in the person's glasses to help them see? Explain
your choice.
Answer:
z
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.
what are 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.

describe the water cycle process starting from an afternoon thunderstorm.
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.

which characteristic of living organisms is responsible for the production of oxygen in the leaf of a plant exposed to sunlight.
Answer:
Photosynthesis.
Explanation:
Photosynthesis is a characteristic of living organisms and it is typically responsible for the production of oxygen in the leaf of a plant exposed to sunlight. It is a chemical process used by plants to obtain food from sunlight.
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the cell organelle where energy from nutrients is released is generally referred to as mitochondria. Animals and plants retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

45. If we put ANY type of cell in pure water: a) is pure water considered hypotonic, hypertonic or isotonic? b) would the cell shrivel or swell? c) what would happen to its turgor pressure (water pressure inside cell): increase or decrease?
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.

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.
