Which statement is always true when describing sex-linked inheritance? It results in a dominant trait. The alleles are found on the X or Y chromosome. The resulting trait is influenced by multiple alleles. It is affected by alleles on at least three different chromosomes.
Answers
Answer:
the second one
Explanation:
there are only 2 sex linked chromosomes and that is X and Y
The true statement when describing sex-linked inheritance is ; ( B ) The alleles are found on the X and Y chromosome
The alleles responsible for reproductive inheritance from parents to offspring is contained in the X and Y chromosome of the reproductive gametes.
The female gametes contains double X chromosomes while the male reproductive gametes contains one X and one Y chromosomes. The alleles that are responsible for inheritance ( i.e. the sex of the offspring ) are contained in this chromosomes.
Hence we can conclude that The true statement when describing sex-linked inheritance is the alleles are found on the X and Y chromosome.

If a cell has 24 pairs of chromosomes in its diploid state, how many
chromosomes will it have after Meiosis 2?
A. 12
B. 24
C.48
D. 6
Answers
Answer:
option A is correct that is 12
Explanation:
meiosis occur in two phases in first phase DNA replication occur and amount of DNA become doubled without any change in the chromosome number and two daughter cell (each 2 n)are formed.
now in stage 2 each daughter cell undergoes mitosis with the formation of two cells with half chromosomes(n)
now 2n=24
n=24/2 =12
after meiosis stage 1...........two daughter cell each with 24 chromosomes
stage 2 .............each daughter cell form two grand daughter cell each with 12 chromosomes
net result.......4 daughter cell each with 12 chromosome(assuming cell as a diploid cell)
If a cell has 24 chromosomes before cell division then the daughter cell resulting from the mitotic division will have 24 chromosomes while the daughter cell resulting from the meiotic division will contain 12 chromosomes each.
The answer is option A.
What are meiotic and mitotic cell divisions?There are sorts of cell departments: mitosis and meiosis. most of the time whilst humans discuss “cellular division,” they suggest mitosis, the procedure of making new frame cells. Meiosis is the sort of cell division that creates egg and sperm cells. Mitosis is an essential technique for lifestyles.

Dump out half of the particles. Place your hand tightly over the top and shake the container. Then remove most of the remaining particles, and shake the container again. Compared with the full container, which states of matter do these two models most closely represent? Explain.
Answers
Answer:
solid
Explanation:
The two models explained are most closely representing the "solid" state.
As in both the models the techniques used are to separate particles through shaking technique and shaking is efficient gravity separation method which helps in separating solid particles such as while dealing with tungsten and tin.
Hence, the correct answer is "Solid".
Answer:
When the container was half full, the particles had more freedom to move around than they did when the container was full. A half-full container represents a liquid. When the container had only a few particles, they had lot more freedom to move about. So, this model represented a gas.

Answers
Answer:
Yes.
Explanation:
Yes, cloning is a form of asexual reproduction because there is no fusion of sperm and eggs takes place. the animal which is formed from this process is identical of that organism because it is produced from the tissue of that single animal. in 1996, first mammal is produced from cloning was sheep named dolly at the Roslin Institute in Scotland. In cloning, the egg is taken from female organism and remove the nucleus from the egg then the desired organism cell is taken and fuse with the nucleus with the help of electricity. Then implant this embryo in the body of first organism from where egg is taken and after that the embryo turns into a baby, this process is called cloning.
Answer:
Yes, cloning is a form of asexual reproduction. The diagram shows that new plants form from a single parent plant, which means that the offspring are genetically identical to the parent.

Answers
Answer:
To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.
Second, the experiment should be carried out under greenhouse conditions.
The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.
By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.

Explanation:
A Detritivore is a heterotrophic organism that feeds on dead plant and animal materials. They could also feed through coprophagy which is nutrition obtained by feeding on feces. Worms that dwell on the soil, insects, and mollusks are examples of detritivores. Detritivores can also be found residing in aquatic environments. Crabs and Lobsters are examples of these organisms.
Detritivores have no teeth. So, they tend to suck in their food, and this food, through peristaltic actions, moves directly into the digestive tract where it is acted upon by digestive enzymes. From the observations, I made about the organism at the mudflat at the ocean, I can conclude that it is a detritivore.

Answers
Answer: b
Explanation: i got the answer wrong and i’m looking at the results rn
Protein is being produced with the help of a process called translation in which mRNA gets translated to produce proteins. The translation is followed after the process of transcription of DNA to RNA.
The cause of the greater influence of protein levels has defined as follows:
The destruction of mRNA could greatly influence protein levels as mRNA is considered the source for proteins to get synthesized. This is because if mRNA gets destroyed, proteins would not have been produced at all. Thus, directly influences the levels of protein.
Thus, we can conclude that mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced. Hence, option (b) is the correct answer.

The question is incomplete,below is the complete question.
Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything?"
You tell the Clinical Nurse Specialist (CNS). As the two of you move him into the bed, you notice that his chest tube bottle is lying on its side on the gurney, with air going into it. When you point this out to the CNS, she immediately grabs the bottle and sets it upright on the floor. You see air start bubbling through the fluid right away. "That was the problem!" she says. "They lost the water seal, and air was going into his chest from the bottle. You would not believe how many times that happens on transport." When you examine Mr. B, you have trouble detecting his lung sounds on the left. Even stranger, his apical heart sound is in the wrong place - it is over toward the right side of his chest. His respiration rate and heart rate are both increased, and he is struggling to breathe. "Let's give him a little oxygen. He'll be a lot better in a half-hour," says the CNS. "Check back on him."
QUESTION - Why would accumulation of air in his pleural space cause his heart sounds to be in the wrong place?
Accumulation of air in Mr B pleural space will cause his heart sound to be heard in the wrong place because the left side is his chest is being filled up with air making the organs in his chest to to be pushed over to the right side.

Answers
Answer: Stimulates the contraction of the uterus during childbirth - OXYTOCIN
Stimulates sperm production and growth of ovarian follicles - FOLLICLE STIMULATING HORMONE
Initiates the Secretion of leutinizing hormone and follicle stimulating hormone - GONADOTROPIN RELEASING HORMONE
Initiates the development of secondary sex characteristics in females - ESTROGEN
Initiates the development of secondary sex characteristics in males - TESTOSTERONE
Initiates cell production of testosterone and estradiol by cells in the gonads - LUTEINIZING HORMONE.
The correct match for hormone and their functions are- 1- Oxytocin, 2- follicle-stimulating hormone, 3- a gonadotropin-releasing hormone, 4- estrogen, 5- testosterone, and 6- luteinizing hormone.
Oxytocin is a naturally occurring hormone that plays a vital role in the reproductive system of both men and women, including labor, delivery, and breastfeeding, as well as in human behavior.
FSH is produced by the pituitary, which is a small gland just below the brain. The pituitary plays a vital role in the development and regulation of sexual function.
Gonadotropin-releasing hormone stimulates the brain’s pituitary gland to produce and release the hormones LH and FSH.
Estrogen is a family of hormones that play a vital role in the reproductive and sexual development of women.
Testosterone is a male sex hormone. It is responsible for spermatogenesis and fertility in males.
Luteinizing hormones (LH) are hormones in the body that stimulate the reproductive system. Luteinizing hormone stimulates ovulation and stimulates the production of the hormones needed for pregnancy
