What phase of mitosis is shown in the diagram below
it is anaphase because yesterday i was studying this so yeah plz Brainlist me plz ill invite u to be my friend
Answer:
A. Telophase
Explanation:
When the anaphase ends, the DNA was separated an run towards both poles of the cell. The fibers from the centrosome retract and the nuclear membrane appears.
Also, when he nuclear membrane appears, DNA become descondensed so the Cytokinesis can begin and divide the plasma membrane to obtain the final two cells.
Where would muscle A in the image set most likely be found?
Lining of a tendon
Lining of the thigh bone
Lining of a heart ventricle
Lining of the intestines
Answer:
Lining of the heart ventricle.
Explanation:
Human heart is divided into four chambers: two atrium and two ventricles. The ventricle is located at the bottom of the heart.
The given diagram correspond to the lining of the heart ventricle. The pulmonary circulation of the heart to the lungs occur through the right ventricle. The wall of the ventricles are thicker than atria.
Thus, the correct answer is option (3).
Muscle A is found in the lining of a heart ventricle.
What are the characteristics of heart muscles?The human heart contains cardiac muscle, often known as the myocardium. Cardiovascular muscle is controlled by an involuntary force.There are three layers that make up the heart: the pericardium, myocardium, and endocardium. Heart muscle is not found in the endocardium. The inner lining of the heart chambers and valves is made up of simple squamous epithelial cells. The epicardium, pericardial space, parietal pericardium, and fibrous pericardium are all components of the pericardium, a fibrous sac that surrounds the heart.The contractility of the heart and consequent pumping motion is caused by the cardiac muscle. The heart muscle must contract with sufficient force and blood flow to meet the body's metabolic needs. The formula for this idea, known as cardiac output, is heart rate x stroke volume.It is based on the heart muscle's ability to contract and how frequently that ability is used. The metabolic demand changes along with the heart's ability to contract.

Essential amino acids cannot be produced by the body, so they must come from our diet. We can get them from eating foods that contain which biomolecule?
A.
protein
B.
complex carbohydrate
C.
fats
D.
disaccharides
Answer:
We can get essential amino acid from eating foods that contain the biomolecule; protein.
Proteins are macro nutrients that contains amino acids. Amino acids are composed of organic compounds such as carbon, hydrogen, nitrogen, oxygen or sulfur which are the building blocks of proteins. The body requires various amino acids for its growth and proper functioning. The essential amino acids such as histidine, isoleucine, lysine, phenylalanine, tryptophan and valine cannot be made by the body but can be obtained through diets. The best sources of essential amino acids are animal proteins such as eggs, meat, and poultry.
Explanation:
In the pea plant, the allele for green pod color (G) dominates the allele for the yellow pod color (g). The Punnet square illustrates a cross for this trait. Which offspring can be described by these genotypes and phenotypes?
the color of the pea pods will be have a more of a chance to be green due to the fact that there is 75% of the square, because the big G means that it will be that color and if it has (gg) then it will be yellow.
Answer:
a) Homozygous offspring with yellow pod color - gg
b) Homozygous offspring with green pod color - GG
c) Heterozygous offspring with yellow pod color - None
Explanation:
It is given that green pod color (G) is dominant over yellow pod color (g).
Thus, an offspring will have green pod color, when its has heterozygous genotype (Gg) and homozygous dominant genotype (gg). While an offspring will have yellow pod color, only when it has homozygous recessive genotype (gg).
Thus, the offspring with under given phenotypes will have following genotypes -
a) Homozygous offspring with yellow pod color - gg
b) Homozygous offspring with green pod color - GG
c) Heterozygous offspring with yellow pod color - None , a heterogygous offspring will be green in color as green pod color is dominant over yellow pod color.
Give an example of allopatric speciation.
Allopatric speciation is said to occur when two groups of organisms are separated by a physical or geographical barrier. Examples of such barriers are ocean, mountain range, rivers, etc. A good example of allopatric speciation is Galapagos finch. Different species of this bird can be found in different islands at Galapos, which is located at Pacific Ocean off South America. The ocean is barrier that isolate the species from one another.

Example of sex linked traits
male tesosterone can affect facial hair, voice deepness, testicle size, muscle mass, agressiveness, etc
Sex-linked traits are determined by genes located on sex chromosomes. In humans, examples of sex-linked traits include certain conditions such as color blindness, hemophilia, and muscular dystrophy. These traits are more common in males because they receive one X chromosome from their mother, which if contains the recessive X-linked trait, it's expressed in males.
Explanation:Sex-linked traits are characteristics determined by genes located on the sex chromosomes. These traits tend to express differently in males and females due to the difference in the sex chromosome composition, XY in males and XX in females.
Examples of sex-linked traits can be seen in human genetics, where the alleles for certain conditions such as color blindness, hemophilia, and muscular dystrophy are X-linked. When a female parent who is homozygous for a recessive X-linked trait, she will pass the trait on to 100 percent of her male offspring, as they inherit their father's Y chromosome.
In addition, females who are heterozygous for these diseases are referred to as carriers, may not show any phenotypic effects, but will pass the disease to half of their sons and carrier status to half of their daughters. Thus, recessive X-linked traits tend to appear more frequently in males than females.

8) What are the differences between asexual reproduction and sexual reproduction?
A) Offspring are produced only by sexual reproduction.
B) An exchange of genetic material only occurs with asexual reproduction. C) Sexual reproduction involves one parent organism, while asexual involves two parent organisms.
D) Asexual reproduction produces offspring identical to the parents, while sexual reproduction produces offspring different from the parents.
Answer:Option D
Explanation:
The continuity of organism on Earth is maintained by the process of reproduction.There are two modes of reproduction. One is sexual reproduction and other is a sexual reproduction.
The asexual reproduction is the process by which identical progeny is produced by single parent. There is no need for two parent.
In case of sexual reproduction the offspring produced is not the exact copy of the parents they show variation. This variation in the offspring provides stability to the organism.

in the process of___, a protein channel helps the diffusion of glucose across the membrane
Facilitated Diffusion
Facilitated diffusion is the type of diffusion in which the molecules are transported across the channels with the help of transport molecules. Facilitated diffusion is the answer.
What are types of facilitated diffusion ?The types of facilitated diffusion are carrier protein transport and the ion channel transport proteins.
In the process of the facilitated diffusion various molecules are diffused across plasma membrane with help from the membrane proteins such as the channels with carriers. A concentration's gradient lives for these molecules such that they all have potential in order to diffuse in (or out of) cell by just moving down it.
Facilitated diffusion thus allows polar with the charged molecules such as the carbohydrates, amino acids , nucleoside and the ions for crossing the plasma membrane. Two main classes of the proteins that helps facilitated diffusion are generally described as : carrier proteins and the channel proteins.

If the concentration of a sugar solution is lower outside the cell than inside the cell, which will happen by osmosis?
The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. ... On the other extreme, a red blood cell that is hypotonic (lower concentration outside the cell) will result in more water flowing into the cell than out.
Answer:
Water molecules will move out of the cell
Explanation:
We are given that the concentration of a sugar solution is lower outside the cell than inside the cell. This means that a concentration gradient of water now exists across the membrane.
In Osmosis, we know that water molecules move from a less concentrated solution into a more concentrated one.
So in this case, water molecules will move out of the cell.
