Which of these is a distinguishing characteristic that can be inherited? *
A. gene
B. cross
C. punnett square
D. heterozygous
Answer:
a. Gene
Explanation:
Gene is a distinguishing characteristic that can be inherited. Therefore, option A is correct.
What are genes?The fundamental structural and operational component of heredity is a gene. DNA is the component of genes. Some genes serve as blueprints for the synthesis of proteins. A gene is actually pretty unremarkable in terms of its physical appearance. Essentially, it resembles any other bit of DNA. They form our genotype and decide our phenotype.
The 23 pairs of chromosomes in cell nuclei plus a tiny DNA molecule present in each mitochondrion make up the human genome, which is a full set of nucleic acid sequences for humans. There are two types of genes that are coding genes and non-coding genes.
Gene is a distinguishing characteristic that can be inherited. Therefore, option A is correct.

A student performed an experiment by placing the de shelled egg in a concentrated salt solution for 5 minutes.What changes did he observe in the egg?Name the process
Answer:
the egg begins to shrink
Explanation:
During the 5 minutes that the egg is in the concentrated salt solution he would notice that the egg begins to shrink. This occurs due to the process known as osmosis which happens when a solvent passes a semipermeable membrane towards where there is a higher concentration which in this case would be within the egg. Since the egg would contain more water than the salt solution causing it to shrivel and shrink.

Which statement is the best decription of how blood circulates through the body?
A. The circulatory system pushes blood upward throughout the body
by using gravity
B. The heart contracts and relaxes causing a force to push the blood
throughout the body.
C. The respiratory system pulls the blood inward when inhaling and
pushes it outward when exhailing.
D. The blood circulates throughout the body by gravity only.
The blood circulates throughout the body because of the contraction and relaxation of the heart which pushes the blood throughout the body. So, the correct option is B.
What is the circulatory system?The circulatory system is a specialized system for the circulation of blood throughout the body. This blood is rich in nutrients obtained from the digestive system after digestion and oxygen obtained from the respiratory system after breathing.
The circulatory system is like an industrial pipeline system in which a pump or motor, pipes and the component flow through the pipes.
The blood vessels represent the pipes. There are two types of blood vessels, the arteries and the veins which carry oxygenated and deoxygenated blood respectively.
The blood is the component flowing through the blood vessels. The blood is a liquid tissue, in which the liquid component is called the plasma and the cellular component is represented by three types of cells. These are the red blood cells, white blood cells and platelets. The nutrients flow freely in the blood plasma and oxygen is carried by the Red blood cells.
The heart is the pump of this system, it contracts to push blood through the blood vessels and relaxes to allow blood into its chambers. The human heart has four chambers.
Therefore, the correct option is B.

Reddish Egret populations in the U.S. Were hunted to near extinction in the early 1900s and the majority of survivors were the dark-feathered morph. This would be an example of:
Answer:
This would be an example of Directional Selection
Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population.
Directional selection increases the proportion of individuals with an extreme phenotypic trait. This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example, Reddish Egret populations were under hunting pressure, which drove them to increase the frequency of dark-feathered individuals, as well as the frequency of the allele codifying for this trait. Dark individuals were the ones that got to survive hunting, they could reproduce and increase in number.

In pea plants, tall (T) is dominant to short (t), and green (G) is dominant to yellow (g). Two parents who are heterozygous for both traits are crossed. What are the possible gametes from the parents genotypes? Why do gametes only have one allele per trait?
Remember to use the FOIL method!
You will have 4 possible answers.
Answer:
TG, Tg, tG, tg
Gametes only have one allele per trait because of meiosis. Meiosis is a two-stage process. Before that stage, the cell is diploid, with two versions of each allele. Afterward, only one version of each chromosome gets sent to each daughter cell. Those daughter cells become gametes, and they each have only one version of each allele.
Explanation:
The parents would be TtGgxTtGg because they are heterozygous.
Think of FOIL like this... (Tt)(Gg) and multiply outer and inner

the anthers in this flower located above or below the stigma
Answer:
The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary. Male reproductive cells travel down the tube and join with the ovule, fertilizing it.
