Answer:
Soil texture is determined by the size and proportion of the particles that make up the soil. Every soil can be separated into three fractions – sand, silt, and clay. Sand particles are the largest and make the soil feel gritty. Silt particles are medium sized and give a smooth, floury feeling to the soil.

4. The diagram below represents a cell in water. Explain why more water is moving out of the
cell than into the cell.
Answer:
One cell has a higher concentration of solutes, and a lower concentration of water thus the water moves down the concentration gradient.
Explanation:
Water in cells readily diffuse across the selectively permeable membrane, or move via osmosis. Here, the water molecules and solutes attempt to maintain equilibrium or balance.
Thus, water moves along its concentration gradient to regions of low water concentration and high solute concentration continuously.

How does chromosomal inheritance generate genetic variation in sexual reproduction?
Answer:
Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
Answer:
Independent assortment
Explanation: When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other. This called is called independent assortment. It results in gametes that have unique combinations of chromosomes.

In determining probabilities all you need to do is count and then divide by the number of results.
What is punnett square?A Punnett Square is a useful tool for forecasting the changes and probabilities that can result from cross-breeding. This includes foreseeing the mating of different species, including humans and animals.
It is asking the chances of having green seeds and that's the recessive allele. For recessive traits to be expressed, there can't be a dominant trait next to it because the dominant trait will always be expressed. So the expected result should be yy (two lowercase) if you want the recessive trait to be expressed.
In the Punnett square of the second generation, there is 1 out of 4 yy genotype. So then divide 1 by 4 and multiply it by 100% to get the probability in percent. So in short, the answer is 25%.

Which organic molecule serves as the main source of energy for cells?
A. Starch
B. Glucose
C. Proteins
Answer:
B. Glucose
Explanation:
Carbohydrates include sugars, starch, cellulose, and glycogen. Carbohydrates are the primary sources of energy for most organisms. The sugar glucose is the main source of energy for cells.
An organic molecule that serves as the main source of energy for cells is known as Glucose. Thus, the correct option for this question is B.
What is the function of glucose molecules?The function of glucose molecules is to serve as an important source of energy. This organic molecule is also known as fuel for living organisms. All those metabolic, as well as, physiologic activities are typically performed by the source of energy which is facilitated by this organic molecule specifically.
Glucose provides immediate energy to the individual in order to make themselves active and strengthen. The molecule of glucose is directly absorbed into your bloodstream and delivers energy to the cells along with the complete body. All cellular processes are performed with the help of glucose.
Therefore, glucose is a type of organic molecule that serves as the main source of energy for cells.

why is vacuole in plant cell larger than a vacuole in an animal cell?
Answer:
The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright. In animal cells, vacuoles are smaller but more in number because they do not require vacuole for rigidity or pressure.

Explanation:
A bird that preys on moths is introduced to the habitat with moths and trees like the ones shown below.
Answer: c. The dark colored moths will experience disruptive selection.
Explanation:
The tree bark is light in color which means that while the light colored moths will be able to blend in, the dark colored moths will not. This will lead to the dark colored moths being hunted more by the bird leading to a sharp decrease in their numbers.
Disruptive selection occurs when an extreme trait is preferred over an intermediate one with little advantage in that environment. The dark moths will experience disruptive selection because the light moths are preferred for survival.

Meiosis is a type of cell division in germinal cells. It produces gametes that contain one complete haploid set of chromosomes. Thus, option B is correct.
What is meiosis?Meiosis is a reductional cell division that occurs in the reproductive or the germinal cells to produce the daughter cells with a haploid (n) set of the genetic material.
The chromosome gets halved and reduced by number in the meiosis I phase of the division. Here, the homologous chromosomes separate and enter daughter cells that are called the gametes.
Therefore, in meiosis, the gametes produced have half the number of chromosomes.
