Answer:
Most cells in our body have two versions of each chromosome (Body cells). These cells are called diploid. We grow and replace these cells with identical cells through a cell division called mitosis.
For sexual reproduction, we need to make cells that have only one version of each chromosome (sex cells). These cells are called haploid. These unique cells are made through a cell division called meiosis.
Explanation:
haploid = 1
diploid= 2 // "di"=2
our body contains 46 chromosomes, half from our dad and a half from our mom. our repoductive contains 23 chromosomes.

if a vector not have origin of replication result in what
Answers
Answer:
What will be the consequence of not having an origin of replication (ori) in the vector? Explanation: In the case ori is absent, the vector won't be able to replicate
Explanation:
As the replication won't take place, only one of the daughter cells would be having the vector. A colony of transformed colonies won't be obtained.
if a vector does not has the origin of replication result in not doing replication as the unit of replication is Ori.
In the case Ori is absent, the vector may not be capable of replicating. As the replication may not take place, the handiest one of the daughter cells might be having the vector. A colony of converted colonies may not be obtained.
What is transgene?
Of these, the maximum usually used vectors are plasmids. Common to all engineered vectors have a foundation of replication, a multi cloning site, and a selectable marker. The vector itself is normally a DNA series that includes an insert (transgene) and a bigger series that serves as the "backbone" of the vector.
Thus it is clear that if a vector does not have an origin of replication result in nonreplicating.

Answers
Answer:
Small vessels that carry blood away from the heart to the capillaries are Arterioles. Muscular-walled vessels that carry blood away from the heart are Arteries. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are Capillaries. Small vessels that connect to the capillaries that carry blood back to the heart are Venules. Vessels that carry blood back to the heart are Veins.
Explanation:
We have different types of vessels in our bodies. We can divide them by their size and structure. Starting from the ones that carry blood away from the heath, we have the arteries. Arteries are vessels of big diameter that have muscle around them. Then, the arteries branch into arterioles, which have a smaller diameter. The arterioles branch into capillaries. These are small vessels with thin walls that allow the exchange of nutrients, wastes, and gases with the neighboring tissues. Once that the blood flows through the capillaries, it goes to the venules, which are small veins that will carry the blood to the veins and these to the heart. The veins do not have muscles in their structures, and their walls are thinner than the ones in the arteries.

Which of the following is made up of 90% water, and 10% dissolved
materials like nutrients, minerals, vitamins, digested food, and salts? *
red blood cells
white blood cells
plasma
O platelets
Answers
Answer:
Plasma
Explanation:
The blood is a key part of the circulatory system. It is a tissue composed of cells that make it up. The blood contains the following components namely; plasma, red blood cells/erythrocytes, white blood cells/leukocytes, and platelets/thrombocytes.
The plasma is referred to as the "liquid" part of the blood and makes up the major part of the blood tissue. The plasma contains 90% water, and 10% dissolved materials like nutrients, minerals, vitamins, digested food, and salts. Hence, based on this question, the answer is PLASMA.

In a FERN PLANT, DNA is located in three different organelles (Option B).
Plants are organisms that have chloroplasts, mitochondria, and cell nuclei.In a eukaryotic cell, the genetic material (i.e., DNA) is mainly found in the nucleus, which is an organelle bounded by a double-membrane (bacteria don't have nuclei).However, mitochondria and chloroplasts are also membrane-bound organelles that have their own genetic material.Chloroplasts are only found in plants and algae (sponges and flatworms don't have chloroplasts).In conclusion, in a FERN PLANT, DNA is located in three different organelles (Option B is correct).

Definition and description of gravity
Importance of gravity
Factors affecting gravitational forces between objects
Relationship between the masses of objects and the gravitational force between them
Relationship between the distance between objects and the gravitational force between
them
Answers
Answer:
1. the force that attracts a body towards the centre of the earth, or towards any other physical body having mass.
2. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe
3. distance between objects
masses of the objects
Explanation:
The magnitude of the gravitational force between two objects is given by
where G is the gravitational constant m1 and m2 are the masses of the two objects r is the distance between the two objects
By looking at the formula, we see that the gravitational force is affected only by two quantities:
- the masses of the objects, m1 and m2
- the distance between the objects, r
4. Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
5. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

1-the force that attracts a body towards the centre of the earth, or towards any other physical body having mass.
2-Gravity is very important to our everyday lives. Without Earth's gravity we would fly right off it. We'd all have to be strapped down
3-Newton's law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them.
Objects with greater mass have a stronger force of gravity between them. ...
Objects that are closer together have a stronger force of gravity between them.
4-5-Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

These groups of stars are also present in the day but they are not perceived due to the extremely high light of the sun. So, they form patterns in the night sky. These groups of stars are not specifically present as they are distributed randomly and can form new images.

Answers
Answer:

The image that best illustrates the magma convection currents within Earth’s interior is the bottom left.
What is Convection?Convection may be defined as a process through which the transfer of heat due to the bulk movement of molecules within a fluid takes place. The current which is produced by the movement of these molecules is known as the Convection current.
Convection currents are present in the mantle region of the earth's surface. In the process of heating, magma rises from deep inside the mantle and then cooled the mantle as it flows down. This cyclic movement of magma constructs convection current within the region of the earth's interiors.
Therefore, the image that best illustrates the magma convection currents within Earth’s interior is the bottom left.
