A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number of digits (five fingers on each hand and five toes on each foot.) The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?a. 9/16.
b. 3/4.
c. 1/16.
d. 1/2.
e. 1/8.

Answers

Answer 1

Answer:

The correct answer is - option D. 1/2

Explanation:

Extra digits on hands and feet mean an individual has six fingers in each hand and feet, this is known as polydactyly. Polydactyly shows an autosomal dominant type of inheritance pattern.

In this case, the mother is normal so she must be recessive alleles and the first daughter is normal so the father must have a recessive allele which means he is heterozygous.

Cross:

Man = Dd

Woman = dd

Their children :

    D      d

d   Dd    dd  

d  Dd    dd

Probability of polydactyl child = 2/4 or 1/2 or 50%

How they formed; extrusive rocks formed from lava and intrusive rocks formed from magma


Where they are found; extrusive rocks are only found above ground


Where they are found; intrusive rocks are only found above ground

Answers

Answer:

The correct answer is - Where they are found; extrusive rocks are only found above ground

Explanation:

Intrusive and extrusive rocks are the two formed in Yellowstone natIonal park but there is how and where they formed that makes them different from one another. they both are igneous rocks.

The major difference between extrusive rocks and intrusive rocks is that extrusive rocks are formed on the surface or above the earth's surface from the lava that is magma thurst out from underground. Intrusive rocks are formed within the crust from the magma after cooling down and solidify.

If cells from one part of an embryo are transplanted to another part, and they develop into the tissue they would have made originally, the cells are said to be ____________ .

Answers

Answer:

determined

Explanation:

Determined cells are embryonic cells that will generate all the cell types of the adult organism, with this process being independent of environmental inputs. Cell determination is defined by specific gene expression patterns in embryonic cells. In consequence, cell determination is defined as a genetic process where a particular cell fate can be broken down into two different states: specified (committed) or determined. If a cell is in a committed/specified state, the cell's fate can still be reversed or transformed, while if a cell in a determined state, the cell's fate cannot be reversed or transformed.

Some pathogens, such as HIV, can be transmitted both vertically and horizontally. How do you expect virulence of such pathogens to compare with that of pathogens that are transmitted?

Answers

Answer:

Some pathogens are transmitted by a single route and others by several, the more transmission routes are recorded, the more pathogens they are, in the HIV virus the transmission is vertical and horizontal therefore it has high pathogenicity, on the other hand, the varicella virus is transmitted only by inhalation.

Explanation:

The vertical route is the transmission through childbirth, it is the moment in which the mother contacts the child's blood and transmits the virus, nowadays the vertical contagion of HIV is highly controlled.

On the other hand, the horizontal route is also called parenteral, it is one that consists of the inoculation of the virus through uncontrolled blood transfusions, intravenous drug addiction by syringe compartment, or uncontrolled injections.

which is true about both endocytosis and exocytosis? check all that apply
they use vesicles for cell transport
they require energy for cell transport
they remove wastes from the cell
they move small, fat-soluble substances

Answers

Answer: they use vesicles for cell transport and they require energy for cell transport

Explanation:

Both endocytosis and exocytosis use vesicles for cell transport, require energy for cell transport. The correct options are a and b.

What is endocytosis and exocytosis?

Endocytosis is the transport of material into the cell, while exocytosis is the transport of material out of the cell.

The distinction can be seen because a vesicle forms around the molecule entering endocytosis. Exocytosis is basically the inverse of endocytosis.

Endocytosis and exocytosis both require energy in the form of adenosine triphosphate (ATP), which is used in the movement of substances into and out of the cell.

Endocytosis is classified into three types: phagocytosis, pinocytosis, and receptor-mediated endocytosis.

Exocytosis is the process by which vesicles fuse with the plasma membrane and release their contents outside of the cell. Exocytosis and endocytosis are both active transport processes.

Thus, the correct options are a and b.

The options of the bases on the complementary model are:

A) CTACCGAC

B) GUCGGUAG

C) GTCGGAAG

D) GTCGGTAG

The answer is D

Explanation:

A DNA molecule is a polymer biomolecule made up of nucleotide bases. It is a double stranded molecule, with each strand containing nucleotides held together by hydrogen bonds. The pairing of nucleotides in one strand of DNA to another follows the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine binds to Thymine (A-T) while Guanine binds to Cytosine (G-C).

Synthesis of ATP by oxidative phosphorylation is a seriously endergonic reaction. What is the immediate reservoir of stored energy that drives this process?

a. the electron transport chain
b. oxygen
c. proton gradient or energized membrane
d. NADH+ H and FADH2
e. glucose

Answers

Answer:

The correct answer is - option C. proton gradient or energized membrane.

Explanation:

The transport chain reaction or system produces the ATP which is caused by the movement of the proton through the internal membrane from the matrix to intermembrane space by the protein complex.

This makes a concentration gradient of protons that moves through the membrane of mitochondria which is utilized by the enzyme known as ATP synthase to produces ATP molecules by oxidative phosphorylation.

Answers

Answer:

d is your answer

Explanation:

Ancestors of Mitochondria were aerobic bacteria, according to endosymbiotic theory.

What is endosymbiotic theory ?

According to Lynn Margulis' endosymbiotic theory, mitochondria in eukaryotes are thought to have originated via an endosymbiotic connection with purple photosynthetic bacteria around 1.5 109 years ago. The endosymbiont, which had been captured, was subsequently transformed into a useful organelle bound by two membranes. Supporting data for the endosymbiont theory.

Prokaryotic cells and mitochondria are the same size. The DNA found in mitochondria is structurally identical to bacterial DNA. Similar to bacteria, mitochondria are self-replicating cells divide by binary fission Two membranes enclose mitochondria, and the inner membrane is structurally very similar to that of bacteria.

Therefore, aerobic bacteria are the ancestors of mitochondria.
