Explanation:

A genetics student is studying a plant that seems to have two Mendelian traits, flower color (red is dominant, and yellow is recessive) and seed color (brown is dominant, and green is recessive).

Use the Table button to create a Punnet square. Your Punnet square should show the possible offspring from one parent that is homologous recessive for both traits and the other parent that is heterogeneous for both traits. For flower color, use F and f, and for seed color, use S and s.

Then, based on the Punnet square you made, answer this question: What are the chances that the offspring will have the red flower, green seed phenotype? Show your work.

Answers

Answer:

Here is the plato answer !!!

   FS         fs       Fs       fS

fs  FfSs    ffss     Ffss     ffSs

fs  FfSs    ffss     Ffss     ffSs

fs  FfSs    ffss     Ffss     ffSs

According to the Punnett square, 4/16       plants will have red flowers and green seeds.

So, (4 ÷16) × 100 = 25% chance of obtaining offspring with red flower and green seed.

The statement that is true is phosphorylated and binds allosterically to glycogen synthase. The correct option is e.

What is phosphorylation?

Phosphorylation is a biological process in which a phosphate group is added to an organic molecule. Phosphorylation processes include the following:

1) phosphate added to glucose to generate glucose monophosphate

2) Phosphate addition to adenosine diphosphate (ADP) to generate adenosine triphosphate (ATP).

Phosphorylation regulates several biological functions, including cell cycle, proliferation, death, and signal transduction pathways.

ADP-phosphate group of a reactive intermediate with the transfer of a chemical reaction in which ATP is created in substrate level phosphorylation.

Therefore, the correct option is e. Be phosphorylated and bind allosterically to glycogen synthase.

where is earth's magnetic north pole?​

Answers

Answer:

The north magnetic pole is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down)

Explanation:

There is only one location where this occurs, near (but distinct from) the geographic north pole. The geomagnetic north pole, a related point, is the pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field.

The Earth's magnetic pole is situated at west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W.

What is the Earth's magnetic pole?

The generation of the Earth's magnetic field occurs deep within the Earth's interior, in a layer which is known as the outer core to be more precise. Here, the convective energy from the slow-moving molten iron is converted to the electrical and magnetic energies.

The north magnetic pole of the Earth moves over time according to the magnetic changes and flux lobe elongation in the Earth's outer core. In the year 2001, it was determined by the Geological Survey of Canada to lie west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W. It was situated at 83°06′N 117°48′W in 2005.
