The complete chart indicating the number of chromosomes after meiosis, in body cells, in gametes and after mitosis are indicated in the given image.

Meiosis is the process of cell division in which the number of chromosomes are reduced to half. This is the reason why it is also called the reductional division. The process occurs in two phases: Meiosis I and Meiosis II. Meiosis I is the phase where actual reduction takes place.

Mitosis is the process of cell division where the daughter cells are identical to the parent cell. Here, the number of chromosomes remain the same and hence is called equational division.

The method "Reduce, Reuse, Recycle"is really important for managing human impacts in our environment. The less plastic we consume (reducing), the better. As much as we can reuse the plastic, the better also. We wouldn't be creating that many trash and would be reducing pollution. Recycling is always the best way to deal with our trash, so it won't be harmful to the environment. However, to really get rid of plastic in our environment it is important to stop producing plastic as well, not only reducing the consume, reusing the plastic and recycling the trash

Explanation:

The goal of the large intestine is to absrob minerals, remaining nutrients, and specially water. So this kind of components must enter the large intestine. Therefore the correct option is A. "Insoluble fibers, waste and water. B./C are not correct, because the food full of nutrientes/ball of food enters the small intestine, before the large one. D. is not correct either, because the food along with enzymes are the products that exit from the stomach.

Option A. Both sodium and potassium ions are transported against their concentration gradient.

A concentration gradient happens when the attention of particles is better in a single area than in every other. In passive shipping, particles will diffuse down a concentration gradient, from areas of better awareness to areas of decreased concentration, until they are frivolously spaced.

In animals, fertilization is to zygote, as meiosis is to (5) gamete.

Fertilization is the process of fusion of the male and the female gamete in order to form new organism which is diploid in nature. This process occurs only in the sexual mode of reproduction and unlike asexual reproduction, presence of two parents is essential in this.

Gamete is the germ cell that is involved in the process of sexual reproduction, in order to give rise to a new organism. Gamete is haploid in nature because it fuses with another gamete of the opposite sex in order to establish the diploid nature.

Explanation:

According to the given statement  The average atomic mass of rubidium is 85.468 .

The average mass of an element's atoms measured in atomic mass units is known as its atomic mass (amu, also known as daltons, D). The mass of each isotope is divided by its abundance to create the atomic mass, which is a weighted average of all the atoms of that material.

Given that the abundance of the ⁸⁵Rb isotope is 72.17% and its atomic mass is 84.912amu

We get 84.912 x 0.7217 = 61.281

And the abundance of the isotope ⁸⁷Rb, having an atomic mass of 86.909, is 27.83%.

We get 86.909 x 0.2783 = 24.187

Thus we get 61.281 + 24.187 = 85.468 as the average atomic mass of Rubidium.

Answer and explanation

Endoplasmic reticulum (ER) is a tubulus membrane that is found in the cytoplasm of the Eukaryote. It's structure consists of the nuclear envelope and the pheripheral endoplasmic reticulum.

Endoplasmic reticulum is divided into 1. smooth ER and 2. rough ER

1. Rough ER - has large numbers of ribosomes attached to the outer surfaces of the lamella membranes, this is the area of ribosomes important for protein production, storage and export. The modified proteins move slowly along the inside of the rough ER until they are packed into small vesicles of the endoplasmic reticulum. After packaging, the proteins are moved by elements of the cytoskeleton either to the Golgi apparatus or to the plasma membrane.

2. Smooth ER - Is involved in the synthesis of steroid. On the surface of smooth ER, there are no ribosomes, therefore it does not participate in the formation of proteins. Its function is to contains many enzymes and other proteins, in liver cells, that have the ability to detoxify a wide range of drugs and poisons.

According to the graph, the inclination of the ramp does not affect the speed of the toy car.

Speed refers to the rate of change of position of an object. Speed is measured as the ratio of distance covered by a body to the time in which the distance is covered. Speed is also defined as the rate of distance covered with time. The SI unit of speed is the combination of the basic unit of distance which is the meter and the second basic unit of Time. Thus, the SI unit of speed is meters per second. The formula of speed is

speed = distance time.

Velocity also refers to the speed of the object but in velocity, the object is moving in a specific direction.

According to the graph, there is no effect of the inclination of the ramp on the speed of the toy car but there is a direct effect on the distance of the ramp and the speed of the toy car. We can see in the graph that when we increase the distance of the ramp, the speed of the toy also increases and vice versa.

So we can conclude that there is no effect of the inclination of the ramp over the speed of the toy car.
