Answer:
none (zero frequency)
Explanation:
The complementation test is widely used in genetics for assessing whether two mutations associated with a phenotypic trait represent two different gene variants of the same gene (i.e., two alleles of the same gene) or if they are mutations associated with two different genes. In a recessive trait, the offspring must receive one recessive allele from each parent in order to show the recessive phenotype (in this case, albinism). Moreover, in heterozygous individuals for a trait that exhibits complete dominance, recessive alleles always are masked by dominant alleles. Albinism is a multigenic (polygenic) recessive trait, thereby individuals who carry recessive mutations causing albinism on different genes will have zero probability (none) of having offspring with albinism.
Answer:
albinism frequency ---> 3/4 = 75% = 0.75 of the progeny will be albino.
Explanation:
Available data:
Albinism can be caused by recessive mutations in different genes that cause a total lack of melanin pigment.Two people with albinism mate to produce offspringThe two people carry mutations in different genes that each cause albinismLet us say that genes A and B are involved.
Gene A: AA and Aa individuals will express pigments, while aa individuals will be albinosGene B: BB and Bb individuals express color, while bb are albinos.Cross: two people with albinism that carry the mutation in different genes
Parentals) Aabb x aaBb
Phenotype) Albino both parents
Gametes) Ab, Ab, ab, ab
aB, aB, ab, ab
Punnett square) Ab Ab ab ab
aB AaBb AaBb aaBb aaBb
aB AaBb AaBb aaBb aaBb
ab Aabb Aabb aabb aabb
ab Aabb Aabb aabb aabb
F1) 12/16 will be albino
4/16 will express color
4/16 will be Aabb
4/16 will be aaBb
4/16 will be aabb
12/16 = 3/4 = 75% = 0.75 of the progeny will be albino.

Explanation:
Accelerate 2022
The mantle is so hot that it allows the rocky material to flow gradually. The correct option is D.
What are the layers of Earth?The crust, mantle, outer core, and inner core are the four principal parts that make up the earth's structure.
Each layer has a distinct chemical make-up, physical state, and potential to affect life on the surface of the Earth.
The crust, mantle, and core are the three layers that make up the earth. This stratum of the earth lies on the surface and is composed primarily of granite and basalt solid rock.
Oceanic and continental crust are the two different types. The majority of the oceanic crust is made of basalt and is denser and thinner.
The Earth's mantle is regarded as being semi-solid. Because the mantle is so heated, the rocky material can flow gently.
Thus, the correct option is D.

which of the following requires ATP
A. facilitated diffusion
B.Simple diffusion
C.Active transport
D.None of the above
Answer:
Active transport
Explanation:
The process is considered "active" due to the use of ATP and actively requiring energy to transport molecules. Simple diffusion simply occurs through the membrane and facilitated diffusion uses transport proteins, but not ATP, hence why both are considered forms of "passive" transport.

1. c . The life cycles of insects and animals all start from a fertilized egg.
2. d . A bee goes through a pupa stage, while the grasshopper goes through a nymph stage.
3. b . I and II
Explanation:
The egg fertilization is very important for the emergence of almost all organisms. If the egg is fertilized then it will change into an organism otherwise no organism is produced from that unfertilized egg. The bees has four distinct life stages i.e. the egg, larva, pupa and adult whereas grasshopper has three stages i.e. egg, nymph, and adult. A moth and an eagle both start their life cycle as a fertilized egg and moth and an eagle both hatch from an egg which is laid by the mother outside of their body..

The image shows a group of fish.
Which type of social behavior is shown in the image?
Oherding
O dividing labor
O schooling
O flocking
The image shows a group of fish in which Schooling type of social behavior is shown in the image. Hence option C is correct.
What is Schooling?In biology, a group of fish that stay together for social reasons are shoaling, and if the group is going from one place to other in the same direction in a coordinated manner then it is called as schooling.
Flocking is a behavior in which objects move or work together as a group. this is seen in the birds, when a group of birds goes for a work we call it as flock of birds.
when a subgroups of animal is performing different tasks in a big group is called as dividing labor behavior.
In this picture we can see that a group of fish is swimming from one place to other therefore it is called as schooling social behavior of the fish. Hence option C is correct.

Identify the following particles as being charged or uncharged/neutral. If charged, indicate whether they are charged positively or negatively. (n = neutron, p = proton, e = electron)
*particle C
proton +20
electron -18
urgent ^^
Answer:
Particle A is negatively charged.
Particle B is neutral.
Particle C is positively charged.
Explanation:
Particle A is negatively charged because the number of electrons is more than number of protons so the particle gain negative charge. Particle A is neutral due to same number of proton and electron which cancels the effect of one another and become neutral whereas the Particle B is positively charged due presence of more number of protons as compared to number of electrons so the particle gain positive charge.

If a new variety of a tree was produced by botanists through selective breeding that had a growth rate 3 times that of the trees in the scenario, how would that have affected the outcome of the simulation?
Answer:
Greatly affected the outcome simulation.
Explanation:
This fast growth have greatly affected the outcome of the simulation because the tree takes less time to mature and completed its growth stages faster as compared to the old tree. The selective breeding included certain hormones that increases the rate of growth in the tree which leads to change and affected the outcome of the simulation.

how are carbohydrates digested
Explanation:
dbbdhdhdhxhxbxbbxbxbxbcbxbcbcchcbbcbcbcbcbcbcbccbcbcbbcbcbc
Answer:
The mechanical and chemical digestion of carbohydrates begins in the mouth. Chewing, also known as mastication, crumbles the carbohydrate foods into smaller and smaller pieces. The salivary glands in the oral cavity secrete saliva that coats the food particles. Saliva contains the enzyme, salivary amylase. This enzyme breaks the bonds between the monomeric sugar units of disaccharides, oligosaccharides, and starches. The salivary amylase breaks down amylose and amylopectin into smaller chains of glucose, called dextrins and maltose. The increased concentration of maltose in the mouth that results from the mechanical and chemical breakdown of starches in whole grains is what enhances their sweetness. Only about five percent of starches are broken down in the mouth. (This is a good thing as more glucose in the mouth would lead to more tooth decay.) When carbohydrates reach the stomach no further chemical breakdown occurs because the amylase enzyme does not function in the acidic conditions of the stomach. But the mechanical breakdown is ongoing—the strong peristaltic contractions of the stomach mix the carbohydrates into the more uniform mixture of chyme.
Explain how cellular processes must be altered in stomach cancer cells compared with normal stomach cells to result in the different levels of SIRT3 expression observed.?
Answer:
SIRT3 is a tumor suppressor gene that controls essential cellular processes including apoptosis, cell proliferation, survival and anoikis resistance
Explanation:
The Sirtuin-3 (SIRT3) gene encodes for a histone deacetylase enzyme involved in the epigenetic regulation of many essential genes, thereby controlling their expression levels. SIRT3 has a proapoptotic function that initiates apoptotic events in cancer cells. Moreover, SIRT3 also modulates cell proliferation and survival in both normal and tumorigenic cells by controlling the expression of genes that maintain Reactive oxygen species (ROS) at non-toxic levels. Finally, SIRT3 also mediates anoikis resistance (i.e., the resistance to detachment-induced cell death), thereby inhibiting tumorigenesis in cancer cells. It is for all these reasons that it has been proposed that SIRT3 represents a potential drug target for cancer therapy.
