Answers:
46 chromosomes will be found in such division.
Explanation:
Mitosis is a type of cell division in which a parent cell divided into two daughter cells and each daughter cells carries the same number of chromosomes as the parent cells and the daughter cells are genetically identical to the parent cells. This type of cell division occur in protists, fungi and plants.
If the parent have 46 chromosomes, each daughter cell will have 46 chromosomes.
Each haploid cell will have 46 chromosomes.

What occurs when there is a higher concentration of molecules on one side of a membrane and the molecules flow to the other side to balance the concentration
Fusion
ОООО
Simulus
Conversion
Answer:
Diffusion
Explanation:
The concept of diffusion states that molecules like to travel from areas of high concentration to low concentration.
Let's think about an example. Let's say you are having a party at your house and in one room there is 100 people and in the other room connected to it, there is only 10 people. What do you think is going to happen as time passes? Right, people are going to move to the room where there is less people so as to equally disperse themselves across the area. The same thing happens within our body with ions and gases.
Ions can diffuse into or out of cells based off their concentration gradients. If there are too many ions on one side, they will simply move to the other side. There are different types of diffusion. Passive diffusion and facilitated diffusion, but those are for a different conversation.

Which of the following answer choices would be a sex chromosome aneuploidy in a human? Choose 1 answer: Choose 1 answer: A A sperm has one X chromosome. B An egg contains two X chromosomes. C A female gamete contains one X chromosome. D A male gamete has only one Y-chromosome.
The answer you are looking for is B.If fertilized by a sperm cell that contains a Y chromosome the individual will suffer from Klinefelter syndrome. If fertilized by a sperm cell that contains an X chromosome the individual will suffer from triplo X syndrome.Both heterosomal aneuploidies.
The following choice would be a sex chromosome aneuploidy in a human is that a sperm has one X chromosome. Option A is correct.
Sex chromosome aneuploidy is a condition in which a person has an abnormal number of sex chromosomes. The normal number of sex chromosomes in a human is 46, with 23 chromosomes in each sex cell. Females have two X chromosomes in their sex cells, while males have one X chromosome and one Y chromosome in their sex cells.
A sperm with one X chromosome is an example of a sex chromosome aneuploidy because it has one fewer X chromosome than the normal number. This condition is called Turner syndrome, and it is characterized by short stature, underdeveloped ovaries, and other physical abnormalities.
The other answer choices are not examples of sex chromosome aneuploidy because they do not involve an abnormal number of sex chromosomes. Option A is correct.

Meiosis reduces chromosome number and rearranges genetic information. Explain how the reduction and rearrangement are accomplished in meiosis. Several human disorders occur as a result of defects in the meiotic process. Identify one such chromosomal abnormality; what effects does it have on the phenotype of people with the disorder
Answer:
Explanation:
Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.
The reduction is accomplished by 2 divisions after the duplication of chromosomes
- first division: separation of homologous pairs of chromosomes (this reduces the total in half)
- second division: separation of sister chromatids of a chromosome.
The rearrangement in meiosis occurs by crossing over/genetic recombination.
This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation
An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.
This condition produces offsprings that have some characteristic facial features, short stature etc
Rearrangement takes place at the time of meiosis with the lining of chromosomes pair during the metaphase 1 and 2. Down syndrome is the example of chromosomal abnormality.
• A process in which a single cell differentiates two times to generate four cells comprising half the original amount of genetic information is termed as meiosis.
• During meiosis, the process of rearrangement takes place when the chromosomes line up in pairs at the time of metaphase 1 and 2. Then in anaphase 1 and 2, the separation of these chromosomes takes place and each gamete gets one of each kind of chromosome.
• One of the examples of chromosomal abnormality is Down syndrome, which is, illustrated by the third copy of chromosome 21. The phenotypic variability, which takes place during Down syndrome is muscle hypotonia at the time of birth, and cognitive impairment.
Thus, during meiosis reduction and rearrangement of chromosomes takes place, and one of the chromosomal abnormality is the Down syndrome.

Which statements describe transform boundaries? A) Rift valleys are formed. B) Mountains are created. C) Faults form in the lithosphere. D) Plates move toward each other.
Answer:
C) Faults form in the lithosphere.
Explanation:
Faults form in lithosphere is part of transform boundaries because the plates simply slide past each other without causing any change to the lithosphere (i.e it is neither created nor destroyed) which is why transform boundaries are also sometimes referenced when we speak about phenomena related to when plates slide in opposite directions.
Answer: c. Faults form in the lithosphere.

Un jardinero cruzó dos plantas de flores rosadas, con la esperanza de obtener plantas con flores del mismo color. Su sorpresa fue encontrar que, en la descendencia, aparecían flores rojas, rosadas y blancas en la proporción 1:2:1. Pregunta: a) ¿En qué se diferencia la herencia del color de estas flores y la de los guisantes? b) Indica el genotipo de las plantas del cruzamiento descrito.
Answer:
Este es un ejemplo de dominancia incompleta. Es una ocurrencia genética que ocurre cuando un gen dominante no expresa su manifestación completa en el alelo recesivo en un alelo dominante heterocigoto.
Por lo tanto, ambos rasgos se manifiestan, lo que resulta en la combinación de los dos alelos para los colores (blanco y rojo). Se dice que el alelo rojo dominante exhibe un dominio parcial sobre el alelo blanco recesivo, y esto da como resultado el alelo completamente rosado.
De acuerdo con la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas heterocigóticas dominantes deben ser R. El alelo blanco es recesivo (rr) enmascarado por el rojo R,
Sin embargo, cuando se cruzan los dos alelos heterocigotos rojos:
Los fenotipos están en forma de
RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.
Esto ocurre porque el alelo rojo dominante no era total / completamente dominante en el alelo recesivo blanco en cada uno, lo que da como resultado un alelo rosa (el tercer fenotipo)
This is an example of incomplete dominance.It is a genetic occurrence which occurs when a dominant gene does not express it full manifestation on the recessive allele in an heterozygote dominant allele.
Therefore,both traits are manifested which results in the blend of the two allele for colors(white and red).The dominant red allele is said to exhibit partial dominance over the recessive white allele.And this results in the entirely pink allele.
Based on Mendelian law the two red flowers are heterozygotes .Therefore, Red heterozygote dominant flowers should beRr.The white allele is recessive(rr) masked by the R-red,
However,when the two red heterozygote alleles are crossed:
The phenotypes are in the form of
RR,(1) red Rr Rr(2) pink rr(1)White.
This occurs because, the dominant red allele was not fully/completely dominant on the white recessive allele in each,which results in pink allele(The third phenotype)
Explanation:
The branch of science which deals with living beings is called biology.
The language of the question is different so it is difficult to answer it.
According to the data given in the question, they are discussing incomplete dominance because the ratio is 1:2:1.
The cross in which the dominant parent is not able to show its character and does not able to suppress the recessive gene. In this case, the plants show the character of somewhere in between both of the cases.
Therefore, they get the ratio of 1:2:1 which indicates the phenotype of red: pink: white.
Hence, the correct answer is incomplete dominance.

Explanation:
A stimulus generally refers to a detectable change in the environment of an organism. These changes could be physical or chemical and could be in the internal or external environment of organisms.
Organisms react to changes in their internal or external environment by responding appropriately. Hence perceiving the smell of rotten egg, feeling the hotness of a dish by touching it, and feeling cold immediately one jumps into a cold pool are all examples of stimuli and their corresponding responses would be covering one's nose, pulling the hand away, and shivering of the body in order to counter the cold.
In other words:
smelling rotten eggs - covering your nose
touching a hot dish - pulling your hand away
jumping into a cold pool - shivering

During interphase the cells copies it’s DNA. In the pictures it shows a chromatid duplicating into a sister chromatids.
What do you mean by interphase of cell cycle?The interphase is the period when the cell is in a non-dividing state and this can be in different stages: the first gap (G1) between the last mitosis and the S phase (phase of DNA synthesis) and the second gap (G2) between the completion of the S phase and the next mitosis (M).
Moreover, interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

What might be the correlation between the clarity of the lake water and the occurrence of the full body plate trait? What might you conclude about the clarity of the water from 1950 to 1980 based on this correlation?
Answer:
The clarity of the lake water isn’t specified so assuming the clarity improved and other predatorial fish were able to target stickleback fish more easily the full body plating had to come into play to make it more difficult for them to be preyed upon and to give them a better chance at escape.
Explanation:
The clarity of the lake water though not specified in this context. The full
body plate will help the stickleback fish to escape from its predators.
Water clarity is defined as the amount of light which is able to penetrate into
water bodies thereby making it easier for animals in it to see and hunt
properly for their food.
The improvement in water clarity will give the predatorial fish an advantage
to easily hunt stickleback fish. The full body plate trait will therefore give it a
form of adaptation to enable ity escape from other predators in the water
body.

How does natural selection lead to adaptations of populations?
Answer:
Natural selection leads to adaptation, that is, to a population dominated by organisms that are anatomically, behaviorally, and physiologically well suited to survive and reproduce in a specific environment. ... Species become extinct because they can no longer survive and reproduce in their altered environment.
Explanation:
Answer:Natural selection leads to extinction. Variation of the genome that do not have the information required to survive in an environment are eliminated due to natural selection. The surviving genomes already had the information required to survive or adapt to the environment.
Natural selection does not create information necessary for the adaptation of a population. The information must already exist for adaptation to occur. Natural selection will change the composition of a population by eliminating the poorly adapted.
Examples are the peppered moth of England. There were two varieties the Melanic or dark and the predominate white. When the industrial revolution and burning of coal changed the environment, the Melanic or dark variation was better adapted. The population changed to being predominately melanic. When the pollution caused by the Industrial revolution was brought under control the population reverted back to the predominately white variety. Natural selection only changed the population. Natural selection did not create the adaptation it already existed.

The highlighted structure separates the oocyte from the externally located ________. zona pellucida primary follicle corona radiata granulosa cells
Answer:
Granulosa cells
Explanation:
Foliculogenesis is a dynamic and complex process through which the follicle goes through many stages of development in a short period (approximately 60 days in humans and some chimpanzees).
The stages classification is based on morphological changes such as follicular size or diameter, the number of follicular cell layers, etcetera. These classifications might vary among authors but could be denominated as:
Primordial folliclePrimary follicleSecondary follicle andDe Graaf follicles (This is the one shown in the image)Through each stage, there are certain modifications in the oocyte, follicular cells, and connective tissue. As the oocyte grows, the follicular cells might reach a size twice or three times bigger than the ones of the primordial follicles. Their shape also changes and they adopt an aspect of stratified epithelium. Their cytoplasm gets a granulous aspect, after what these cells receive the name of granulous cells. The De Graaf follicle characterizes for having a space named follicular antro that displaces the oocyte to one of the sides.
The oocyte at this point gets surrounded by zona pellucida and corona radiata .
The follicular antro (The highlighted structure) separates the oocyte from the externally located granulosa cells or follicular cells.
