Organelles are specialized structures within eukaryotic cells that perform specific functions. Each organelle has its own unique set of tasks that help the cell carry out its metabolic processes and maintain homeostasis.

Nucleus contains the cell's genetic material and acts as the control center for the cell, regulating gene expression and cell division. Mitochondria is responsible for generating the energy needed by the cell through cellular respiration. Endoplasmic reticulum (ER) is involved in the folding and modification of proteins, lipid synthesis, and the transport of molecules within the cell.

The area where the land meets the sea is called the coastline. This area can have different physical features depending on its location. Some common features of coastlines are beaches, cliffs, bays, harbors, estuaries, and dunes. Beaches are made up of loose particles like sand and gravel that are deposited by the sea.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

The period of time when sexual intercourse takes place between two organisms is called mating. However, all the matings need not end in fertilization.

The gestation period is a time when the embryo develops completely into a fetus. This is usually from the time of fertilization to the time of giving birth.

Let us take the comparison of the gestation period of 3 mammals.

The gestation period of a cow varies from 279- 287 days. The mating between the bull and cow occurs during the heat or oestrus period of the cow. At that time the bull mounts on the cow or vice-versa may happen during the mating period. This is termed bulling.

In the case of horses, the gestation period is 320-380days. The mating ritual in a horse is a bit different than in a cow. It usually has three phases of sexual behavior which includes: courtship, mating, and post mating behavior. During courtship, the stallion which is the male horse will approach the mare, prance, sniff her, nuzzle her, and groom her. The mare which is the female horse may squeal, kick, or move away to show the stallion that she is not ready. When the mare is receptive to breeding, she may stand still, deviate her tail, and urinate, leading the stallion to mount her. It usually breeds well in pastures than in controlled environmental breeding conditions.

Whereas in camels, the gestation period is far longer than in cows and horses. It is about 360-440days. The male camel displays its organ called a dulla to show out is ready for mating. The male camel Urinates on its own tail and swishes it over its back so that the Urine contains female-attracting pheromones. It shows distinct violent behavior towards other male camels. The female camel undergoes an estrous cycle in the breeding season which lasts receptive for 3-4 days, and non-receptive following the other 10 days. In the receptive period, the camel sits down and exposes its genitalia for the male camel to copulate. The whole mating takes about 20 minutes and is accompanied by gurgling and frothing by the male and bleating by the females.

It should be noted that African elephants have longer gestation periods like Asian elephants whereas no other animal has a longer gestation period than an elephant or a shorter gestation period than mice.

Answer:

Transfer of Heat

You might have observed that a frying pan becomes hot when kept on a flame. It is because the heat passes from the flame to the utensil. When the pan is removed from the fire, it slowly cools down. Why does it cool down? The heat is transferred from the pan to the surroundings. So you can understand that in both cases, the heat flows from a hotter object to a colder object. In fact, in all cases heat flows from a hotter object to a colder object.

Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

Explanation:

Let us go option by option :

1) Genes are located in chromosomes. TRUE

Chromosomes are in cell nucleus. A chromosome contains hundreds and thousands of genes. A normal have 23 pairs of chromosomes, and a total of 46.

2) Chromosomes are the in nucleus.

TRUE

Chromosome is structure found in nucleus of the cell. It is made up of protein and DNA.

3) A single Chromosome can contain hundreds of genes.

TRUE

single Chromosome can contain hundreds of tgenes.

4) All of the above

TRUE

As all the statements above are true. The correct option is 4.

Answer:

Answer:

The atom has 9 electrons

Explanation:

I don't see a list of possible choices, but as for what I can guess this is the correct answer. An atom with the same number of electrons as protons will be neutral, as stated in the problem. If this isn't what you are looking for. some other possible answers are the atomic weight will be 19, the atom has 10 neutrons, the atom has 9 protons, and the atom is a fluorine atom.

An atom generally consists of three important subatomic particles. They are protons, neutrons and electrons. Here the given atom has 19 subatomic particles, 10 of them are chargeless. So the atom is Fluorine.

The particles which are smaller in size than an atom are defined as the subatomic particles. The positively charged subatomic particles are called the protons whereas the negatively charged particles are called the electrons. The neutrons does not have a charge.

The number of protons or electrons in an atom is the atomic number. Here the atomic number of Fluorine is 9, so it has 9 protons and electrons. The atomic mass of fluorine is 19.

The number of neutrons in Fluorine is given as:

No: of neutrons = Mass number - Atomic number

19 - 9 = 10

Thus the given atomic model is of Fluorine.
