Biology In which stage of the cell cycle does dna duplicate

Answer:  

(1)  m = -5, b= 1

    [tex]\frac{x}{a} + \frac{y}{b} = 1[/tex]  

put b=1 (given)

[tex]\frac{x}{a} + \frac{y}{1} = 1[/tex] => y = -x/a + 1

-1/a is representing slope here which is given as -5

-1/a = -5 => a = 1/5

slope intercept form

y = mx +b

y = -5x + 1

standard form

5x +y = 1

(2). (1, -2), (3, 3)

m = 5/2

slope intercept form

y - 3 = 5/2*( x -3)

y = 5x/2  -9/2

standard form

5x -2y = 9

(3). (-2, 0) and (0,5)

  m = 5/2

slope intercept form

y - 0 = 5/2 ( x+2)

y = 5x/2 + 5

standard form

5x -2y = -10

(4). a = 2, b = -7

   [tex]\frac{x}{2} + \frac{y}{-7} =1[/tex]

slope intercept form  

y = 7x/2 -7

standard form

7x -2y =14

(5). m=2,(3,-1​)

  slope intercept form  

y +1 = 2(x -3)

y = 2x -7

standard form

2x -y = 7

Answer:

Monocot

Explanation:

All flowering plants (Angiosperms) are classified into monocots and dicots. Monocotyledons are plants that have one seed leaf (cotyledon) when the seeds germinate. These plants also have other features such as, for example, parallel-veined leaves, adventitious root system, flower parts in multiples of threes (i.e., 3, 6 or 9 petals), etc. Poaceae (Gramineae), also known as grasses, is a large family of monocotyledonous plants. Therefore, all the grasses are monocot.

In DNA replication, each new double helix is composed of one old DNA strand and one new DNA strand. So, the correct option is (D).

DNA replication is defined as the biological process of making two identical copies of DNA from a single original DNA molecule that occurs in all living organisms, acting as the most essential part for biological inheritance.

It is the process by which the DNA of the genome is copied into cells, where a cell must first copy (or replicate) its entire genome before dividing so that each resulting daughter cell ends up with its own complete genome.

DNA replication involves:

Before DNA can replicate, the double stranded molecule must be "unzipped" into two single strands.

The leading strand is the simplest to replicate.

Thus, in DNA replication, each new double helix is composed of one old DNA strand and one new DNA strand. So, the correct option is (D).

Explanation:

because the mom must be either brown your white and the dad must be the other color

The best explanation for the statement that how two kittens in the same litter can have different fur colors are the brown kitten and the white kitten have different combinations of the genes for fur color. The correct option is B.

The study of genetics covers how a person inherits traits from their parents. It explains how familial traits—be they simple like eye color or complicated like disease susceptibility—run in families.

Both genomics and genetics have an impact on health and disease. The study of genes and how particular traits or conditions are passed down from one generation to another is referred to as genetics. The study of a person's entire gene pool is referred to as genomics.

Therefore, the correct option is B. The brown kitten and the white kitten have different combinations of the genes for fur color.

Answer:

C. O2 moves from the alveoli to the red blood cells.

Explanation:

pls mark brainliest, u don't have to.

I got it correct on edge, have a good day :)

At the site of gas exchange in the lungs, oxygen moves from the alveoli to the red blood cells. Details about gaseous exchange can be found below.

Gaseous exchange is the process whereby gaseous substances especially oxygen and carbon dioxide move from one point to another in living systems.

Oxygen from the atmosphere goes into the body via the nose and is passed on to the lungs. The gases are exchanged in a compartment called alveoli or air sac.

The air sac then passes the oxygen to the red blood cells, which circulate it round the body to organs.

The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case:

1. dominant parent and recessive parent

2. heterozygous parents

Answer:

1. dominant parent and recessive parent:

dominant parents can be represented by LL and recessive parent is represented by ll, so the gametes would be L, L and l, l.

so,

 L    L

l  Ll   Ll

l  Ll   Ll

so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue.

2. heterozygous parents

In this case, parents have Ll genotype and gametes would be L and l for each parent so,

    L    l

L   LL  Ll

l    Ll    ll

In this case, one is pure dominant and two heterozygous whereas only one is recessive so, the phenotype of offspring that cant fol the tongue would be:

3/4 = 75%

Answer:

A.  nutrition

Explanation:

The most likely explanation for the remainder of the variation would be nutrition. Little is known about how exactly nutrition affects genetics and heritability, but it is known that it does. Scientists believe that traits that allow a species to feed more successfully have a drastically increased chance of appearing in offspring as it greatly contributes to their survival. When a trait does not allow the species to gain the proper nutrition, the species tends to develop other traits to accomplish this which then get passed on to offspring.

Answer:

The minimum difference is already the value of 1

Explanation:

When the pH is not balanced between the extracellular and intracellular environment, the cell could go into shock, that is why in the face of the minimal differences in pH between the internal or external environment, the proton pump is activated, this is how the hydrogen ion or positively charged protons cross the membrane and indirectly generate ATP molecules.

Answer:

It has four chambers.

Explanation:

The structure of human heart has four-chambers consist of two atrium and two ventricles. The right atrium receive blood from the whole body, while the ventricles pump blood to the whole body. The right atrium receives blood from the superior and inferior vena cavas. This blood then moves to the right ventricle where it is pumped to the lungs for purification or to dispose off carbondioxide and loaded the blood with oxygen. The left atrium receives blood from the lungs while the left ventricle pumps this blood to all parts of the body.
