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 what phase of meiosis is DNA replicated?
Answer:
During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.

Answer:
Flagellum
Explanation:
Flagellum are the long whip-like extensions that help protists move. They spin quickly, like a boat propeller to move the protist.

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

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.

SOMEONE HELP PLEASE!! State how the digestive, respiratory, and circulatory systems are connected. State how food is eventually used by our cells by involving all systems.
Answer:
Our organ systems in the human body perform functions such as digesting food, breathing and transporting important nutrients for the human body to function properly. Thus, while the digestive system processes food, the respiratory system provides oxygen and the excretor eliminates waste, the circulatory system connects the different systems for the human body to function.
Explanation:
When we eat, we incorporate different nutrients that provide us with the substances and energy that our body needs to function properly. The digestive system allows us to obtain these nutrients, while the circulatory system is responsible for carrying them throughout the body. The nutrition function, which allows the use of nutrients, is carried out by the digestive, circulatory, respiratory and excretory systems. Food, once ingested, is subjected in the digestive system to crushing and chemical transformation (digestion) that results in obtaining simpler substances, converting them into soluble and assimilable substances (nutrients) that are incorporated into the circulatory system and are transported to each of the cells of the tissues. A proportion of the oxygen that is part of the inspired air and that has penetrated the lungs, enters the blood circulation in the pulmonary alveoli. In this way, oxygen enters the circulatory system to be transported to all cells in the body.

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.
Al examinar la aleta de un pez primitivo, los científicos encontraron similitudes entre su estructura ósea y la de los reptiles, las aves y los mamíferos modernos. ¿Que tipos de evidencias describe este caso?
Answer:
evidencia de un antepasado común entre grupos de vertebrados (gnatóstomos)
Explanation:
En el estudio comparativo arriba descripto, se encontraron semejanzas que provienen de un antepasados común. Este tipo de evidencia se conoce como homología, es decir, semejanza entre diferentes grupos de organismos causada por un mismo origen evolutivo. Los gnatóstomos (vertebrados con mandíbula) conforman un grupo de organismos el cual incluye peces óseos, peces cartilaginosos, anfibios, reptiles, aves y mamíferos. En este caso, las extremidades del grupo de los gnatóstomos (las cuales tienen como origen común la aleta de un pez primitivo) son similares porque son estructuras homólogas.
