Answer:
Luster
Explanation:
luster is the only answer that has to do with light. Luster is measured by the way a mineral reflects light.
Cleavage has to do with breaking minerals apart along certain fracture lines. Cleavage is not the answer.
Hardness is a test where one mineral is used to scratch another. The one that does the scratching is harder than the one that is scratched.

Cholesterol embedded in the phospholipid bilayer allows passage of certain molecules.
The phospholipids are flexible and can slide past one another, allowing small gaps that molecules can penetrate.
The phospholipid bilayer allows osmosis while preventing diffusion of H2O molecules.
The phospholipid bilayer provides the cell's protection, while embedded proteins allow passage of some molecules.

Which of the following best describes the genes of offspring of organisms that reproduce sexually?
Answer:
Each of the offspring is genetically unique and received some of its genetic
Explanation:
While reproducing sexually, The zygote receives half of the gametes of male organism while half of the gametes of female organism. This constitutes to the total number i.e. 46 chromosomes.
While the zygote receive half from male and half from female, This means that the offspring produced by the zygote will have both the characteristics in common of the male as well as female. Remember that, Chromosomes contain gene which are particularly responsible for characteristics.
So, Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.

What are TWO factors that could affect the rate of diffusion?
Answer:
Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion.
Explanation:
Which statement best describes codominance and incomplete dominance?
Answer:
This question lacks options, the options are;
A) In codominance and incomplete dominance, both of the alleles are dominant.
B) In codominance and incomplete dominance, neither of the alleles are dominant.
C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.
D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.
The answer is C
Explanation:
Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.
- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.
- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.
Answer:
The correct answer is b
In cats, white spots are caused by a dominant allele called T, while (tt) individuals are solid colored. Also short hair(H) is dominant to long hair(h). What would the probability be of getting a white-spotted, long-haired cat from this cross: TTHh x Tthh? What are the phenotypes of the parents?
Answer:
1. Probability is 1/2
2. Parents phenotypes:
TTHh = white spots, short hair
Tthh = white spots, long hair
Explanation:
This question involves two different genes coding for spot color and hair length in cats respectively. In the first gene, the allele for white spots (T) are dominant over the allele for solid color (t) while the allele for short hair (H) is dominant to long hair (h).
According to this question, a cross between parent cats was performed as follows: TTHh x Tthh. The following gametes will be produced by each parent:
TTHh - TH, Th, TH, Th
Tthh - Th, Th, th, th
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. However, according to the question, 1/2 of the offsprings will probably be white-spotted and long-haired. The phenotypes of the parents are as follows:
TTHh = white spots, short hair
Tthh = white spots, long hair
What is the exchange of genes between
homologous chromosomes called?
A Crossing over
B. Independent assortment
C. Criss-Crossing
D. Meiosis
A. Crossing over
During synapsis in meiosis (when the homologous chromosomes pair together during prophase I), is when crossing over occurs, and the chromatids of the homologous pairs "cross over" and swap genetic material.

Can someone help me with at least one of these questions. I don’t understand it at all.
Answer:
You gotta sketch out a sperm egg under the questions after the example.
Explanation:
You see, there is an example, right? Well, then, depending on how many chromosomes there are, write the correct chromosome number in each cell. Number 1 is just an example of what you gotta do. Mosquito wing cell contains 6 chromosomes. The cell contains at least 42 chromosomes. Do what you saw in the example: egg cell gamete + cell gamete = 1st somatic cell.
Describe the three components that make up the structure of the atom, including their charge and specific locations within atom.
The three components that make up the structure of the atom are as follows:
Electrons (Negatively charged sub-atomic particles). Protons (Positively charged sub-atomic particles).Neutrons (Neutrally or no charge). What is the nucleus of an atom?The nucleus of an atom may be defined as the center of any atom that significantly consists of protons and neutrons.
Due to the positive charge on protons and neutral charge on neutrons, the nucleus of an atom is found to be positively charged.
The electrons are negatively charged sub-atomic particles which are always revolving around the nucleus of an atom.
While protons are positively-charged sub-atomic particles that are present in the nucleus of an atom. And Neutrons are neutral or no charge sub-atomic particles that are present in the nucleus of an atom along with protons.
Therefore, the three components of atom has been significantly described with respect to their charge and specific locations within atom.

True or false: According to trichromatic theory, color blind people could not see the green and red works of art because a part of their eye does not process those wavelengths the same as everyone else.
Answer:
True! I think??
Explanation:
The Trichromatic Theory is the idea that there are three receptors in the retina of the eye that are each sensitive to their own specific color. These three colors are red, green, and blue.
The statement is true According to trichromatic theory, color-blind people could not see the green and red works of art because a part of their eye does not process those wavelengths the same as everyone else.
According to the trichromatic theory of color vision, also known as the Young-Helmholtz theory of color vision, there are three receptors in the retina that are responsible for the perception of colorOne receptor is sensitive to the color green, another to the color blue, and a third to the color red. The combinations of these three colors produce all of the colors that we are capable of perceiving. Researchers suggest that people are able to distinguish between as many as seven million different colors.Photoreceptors also tend to have different sensitivity levels. Blue receptors are the most sensitive and red the least; the ability to perceive color requires interaction between at least two types of photoreceptors. These three colors can then be combined to form any visible color in the spectrum.Learn more about trichromatic theory

If you see caddis fly larva and freshwater shrimp, what is the quality of the water?
Answer:
The water quality is good because they are both sensitive to pollution
Explanation:
The quality of the water is extremely fine when you see caddis fly larva and freshwater shrimp.
How do you determine the quality of water?The quality of water is determined by analyzing several properties like dissolved oxygen, pH, suspended particulate matter, pollution estimation, density, etc.
The member of caddis fly larva and freshwater shrimp always found in the aquatic environment where there is less or no pollution.
These species are adapted to the freshwater ecosystem and hence commonly found in fine quality of water.
