Cell Organ System Organ

Explanation:

cells make up everything as a building block of life.

Answer:

Cell, tissue, and organ.

Explanation:

A cell is an obvious one because it makes up the tissue, and it is needed in order to form an organ. Meaning tissue and cell would have to be included. Tissues witch are made of many cells form an organ, and an organ would be  the human stomach/digestive system. It can't be organ system because a stomach can't be a whole system including the heart and ect. It can't be organism because a stomach isn't enough organ systems to create an organism.

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).

A. Creativity

Creativity is a characteristic or trait in scientists or other answer seekers that allows them to think out of the box. It allows them to look through different perspectives to find new or other solutions to a problem.

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:

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.

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.

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.

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.
