For a quantitative trait explained by four loci in an additive fashion, if the four locus genotype AaBbCcDd corresponds to a phenotypic value of 32, and the four locus genotype AABBCCdd corresponds to a phenotypic value of 48, then what is the phenotypic value corresponding to the four locus genotype AABbcCDD?
Answer:
48
Explanation:
In genetics, additive effects represent a mode of quantitative inheritance that occurs when the combined effects of alleles (i.e., the variants of a gene that lead to differential expression of a phenotypic trait) at two or more loci are equal to the sum of their individual effects, contributing thus to the final phenotype. Therefore, the additive variance can be explained by the sum of the individual effects of identified loci/genes that have an additive effect on this quantitative trait. In this case, each gene shows an additive effect (equal to 8 for each dominant allele), thereby the phenotypic value corresponding to the genotype AABbCcDD will be equal to 48 (i.e., 16 + 8 + 8 + 16 = 48).
What does this process lead to?
Chiasma
Answer: Chiasmata are specialized chromatin structures that link homologous chromosomes together until anaphase I (Figs. 45.1 and 45.10). They form at sites where programmed DNA breaks generated by Spo11 undergo the full recombination pathway to generate crossovers. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. In meiosis, absence of a chiasma generally results in improper chromosomal segregation and aneuploidy.

Do you believe that all of our actions can be attributed to the nervous system? Does your memory of an event trigger your responses? Why or why not?
Answer:
The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.

Choose 1 answer:
А
$37
$50
$90
$150
Answer:
$81
Explanation:
7 times 9 is 63, so they spent 63 dollars on tickets. If 18 dollars are spent on snacks on top of that, then the group of friends spent 81 dollars in total. If you were to estimate the answer before solving it, $90 would be the closest answer of the four listed.
Answer:

The drug Viagra promotes blood vessel dilation by prolonging signaling through nitric oxide (NO). How does Viagra boost NO?
a. It inhibits guanylyl cyclase in smooth muscle cells.
b. It prevents acetylcholine from binding to its receptors.
c. It stimulates guanylyl cyclase in smooth muscle cells.
d. It blocks the enzyme that degrades cyclic GMP.
e. It binds to acetylcholine receptors on endothelial cells.
Answer:
The correct answer is option d, that is, it prevents the enzyme, which degrades cyclic GMP.
Explanation:
Oral therapy for erectile dysfunction is Viagra, which is the citrate salt of sildenafil, it works by preventing a specific phosphodiesterase type 5 or PDE5, which is the inhibitor of cGMP. During sexual stimulation, nitrous oxide is released in the corpus cavernosum causing the erection of the penis in males. The nitrous oxide then stimulates the enzyme guanylate cyclase that further makes the concentration of cGMP to elevate, this generates smooth muscle relaxation in the corpus cavernosum and permitting blood the inward flow of blood.
Viagra works by increasing the influence of nitric acid by preventing PDE5, which is accountable for the deprivation of cGMP in the corpus cavernosum. At the time of sexual stimulation, the discharging of nitrous oxide takes place, the viagra inhibits PDE5 causing the levels of cGMP to elevate in the corpus cavernosum leading to smooth muscle relaxation and continuous flow of blood to the corpus cavernosum.
How does the population growing negatively impact earth
Well as the population grows, our resources start to decrease. More resources are wasted every single day of our lives and we still keep digging them all out, what makes it worse is, since animals keep going endangered, humans keep coming and coming and if it keeps happening we will have no animals. Not to mention people are burning forests, the things we need to breathe.

Sea otters move into the ocean bay. The eat all the sea urchins. This change will cause the
A. Kelp to have less food
B. crabs to have less food
C. Sea ducks to have more food
D.Arctic foxes to have more food
The presence of sea otters in an ocean bay will result in a reduction in the amount of food available to carbs because they feed on sea urchins. Therefore, option (B) is correct.
What is food chain?The linear relationship between creatures that demonstrates how they obtain energy by feeding on one another is referred to as the food chain.
The information provided in this inquiry suggests that sea otters migrate into the ocean bay and consume all of the sea urchins there.
This leads one to believe that they cut down on the food supply of another eater of urchins, such as carbs. Because of this, the introduction of sea otters into the ocean bay will result in there being less food available for carbs.

Potassium thiosulfate (K2S2O3) is used to remove any excess chlorine from fibers and fabrics that have been bleached with that gas. The reaction is K2S2O3 + 4Cl2+ 5H2O→2KHSO4 + 8HCl a. What mass of HCl will be produced at the same time that 45.0 g of KHSO4 is produced? (5 pst) b. What mass of Cl2 is consumed along with 2.20 x 1024 molecules of H2O? (5 pts)
Answer:
The correct answer is a) 48.16 grams of HCl will be produced, b) mass of chlorine consumed is 206 grams.
Explanation:
a) The reaction given is:
K₂S₂O₃ + 4Cl₂ + 5H₂O ⇒ 2KHSO₄ + 8HCl
Based on the given information, the mass of KHSO4 is 45 grams. The moles of KHSO4 can be determined by using the formula,
Moles = given mass/Molar mass
= 45/136.16
= 0.33 Moles of KHSO₄
From the reaction it can be seen that when 2 moles of KHSO₄ is produced, 8 moles of HCl is also produced. Therefore,
2 moles of KHSO₄ = 8 moles of HCl
So, moles of HCl will be,
Moles of HCl = 8 × 0.33/2
= 1.321 moles
Now the mass of HCl is,
Mass of HCl = Moles of HCl × Molar mass of HCl
= 1.321 × 36.46
= 48.16 grams of HCl
b) It is known that 1 mole is equal to 6.023 × 10²³ molecules
In the given case, the molecules of water is given, that is, 2.20 * 10²⁴ molecules. Now let us consider that the moles of water is x.
x mole of water = 2.20 × 10²⁴ /6.022 × 10²³
= 3.653 mole of H2O
From the reaction given, it can be seen that when 5 moles of water are consumed, 4 moles of chlorine are consumed.
5 moles of water = 4 moles of chlorine
3.653 moles H₂O = x moles of Cl₂
Moles of Cl₂ = 4 × 3.653 /5
= 2.906 moles Cl₂
Now the mass of Cl₂ determined as,
Mass of Cl₂ = moles of Cl₂ × Molar mass of Cl₂
= 2.906 × 70.9
= 206 grams

Definition: This is the location where two or more bones make contact. This junction allows for
movement and structural support.
CAN SOMEONE PLZZ HELP REPORT CARDS ARE DUE TOMORROW
Answer:
Joint.
Explanation:
A joint can be defined as the location where two or more bones make contact.
Also, a ligament refers to a short elastic band-like tough fibrous tissue that holds the bones of a joint together so as to keep them in place. This joints are able to move (lengthen and shorten) as a result of the presence of muscles.
Basically, this junction known as joints are typically found in vertebrates and it allows for movement and structural support.
Hence, the ability of the human body to make movements such as sitting down, kneeling, standing up, bending, walking, running etc., is solely dependent on the joints. Thus, without joints all vertebrates would be completely rigid and static.
