Answer:

According to the diagram, step 3 indicates the S phase of cell cycle, which corresponds to the DNA replication phase.

Explanation:

In the S phase of the cell cycle the nucleus contains twice the amount of its genetic charge, due to increased DNA replication, resulting in each chromosome forming two chromatids.

This is a relatively long phase, and is part of the preparation process that occurs before an imminent division. In the diagram it is indicated by the number 3.

The S phase is named for the abbreviation of Synthesis.

2. In sheep black wool is recessive to white wool. What happens when you mate a black ram (male) to a heterozygous ewe (female). W= white, w = black.

Answers

Answer:

50% will be white (Ww) and 50% will be black (ww)

Explanation:

Here's what the punnett square should look like.

In order for the black ram to have its coloring it would need to have 2 recessive genes (ww). The female is heterozygous, meaning she carries both genes (Ww) but only exhibits the dominant gene, in this case white fur (though they can pass the recessive gene on to their children). Simply filling out the punnett squares shows the outcome of the offspring.

Which phase determines the length of whole cell cycle? ( ) A. G1 phase B. G2 phase C. M phase D. S phase

Answers

Answer:

D

Explanation:

The S phase determines the length of the whole cell cycle.

The S phase of the cell cycle is the phase during which the cell's DNA is replicated in the nucleus while the centrosome is replicated in the cytoplasm. This phase determines the length of the whole cell cycle because the time it takes to replicate a DNA varies according to the total DNA present in the cell. The rate of DNA replication is relatively constant from cells to cells and species to species. Hence, the more the DNA, the longer the time it will take for its replication.

For example, if cell A and cell B are similar in every way except that A has higher amount of DNA than B, it will take a longer time for cell A to complete S phase than cell B. Therefore, cell A will have a longer cell cycle than cell B.

what is fhe importance of cell membranes​

Answers

Answer:

Importance of cell membrane

Explanation:

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Cell membrane is there to control what goes in out of the cell.

Some bacterial cells secrete a chemical that allows other bacterial cells to determine the density of bacterial cells in the area. They use this to determine if their population is large enough to begin certain functions, like forming a protective biofilm together.

Based on this type of chemical signaling, which of the following demonstrates the same type of chemical signaling?

A. B cells engage in cell-to-cell recognition with helper T cells, exchanging antigen information the B cell has on its cell surface.
B. Cells that secrete oxytocin also use oxytocin for autocrine signaling, helping it to down-regulate production when needed.
C. During development, human nerve cells participate in paracrine signaling to determine what other nerve-cell types are in the area to adjust their placement.
D. Some animal cells can form junctions with other animal cells to directly share information.

which part of the blood transports insulin to its target organs?

Answers

Answer:

endocrine glands

Explanation:

The part of the blood that transports insulin to its target organs is plasma

BLOOD:

The blood is a crucial part of the circulatory system. It functions majorly as a carrier tissue in the body. The blood carries substances like hormones, glucose, carbon dioxide, oxygen etc. from one location to the other.

The blood is, however, a tissue made up of different cells and components namely: erythrocytes, leucocytes, plasma, platelets.

The plasma component of the blood is its liquid part and makes up majority of blood's volume. The plasma is the medium in which most substances in the body dissolves and transported.

Therefore, the part of the blood that transports insulin to its target organs is plasma.

Answers

Answer:

FACTORS INFLUENCING CHEMICAL BONDS

Ionic bonding is a chemical bond between a positive ion and negative ion. Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.

CHARACTERISTIC OF IONIC BONDS

Ionic compounds are hard and brittle. Ionic compounds dissociate into ions when dissolved in water. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. An ionic compound can be identified by its chemical formula: metal + nonmetal or polyatomic ions.

CHARACTERISTIC OF COVALENT BOND

Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
