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:

The total energy but the photons will give is 6.615 x 10^-14

Explanation:

Formula that can be used in this question is E= hf or E= hc/ λ

This is the formula that can be used to calculate the energy that the photon is carrying where it is given as the Planck's Constant .

Now putting the values given in the equation that can calculate energy we get Planck's Constant is equal to 6.62 x 10^-34

E=(6.62 x 10^-34 x 2.998 x 10^8) / ( 3 x 10^-12 )

E=6.615 x 10^-14

Answer: Jewelers add different metals to strengthen the material and improve durability during wear. The resulting mix of two or more metal elements is called an alloy. For instance, pure silver bends and scratches quite easily. A metal alloy for jewelry, like sterling silver, is a better solution for most applications.

Answer:

I hope its correct! here is what I found.

An alloy is a mixture of two or more elements, at least one of which is a metal. Alloys are created to give the resulting material improved properties such as increased strength, improved corrosion resistance, or improved electrical conductivity.

Jewelers use alloys in jewelry for several reasons. One is that many pure metals are too soft to be used in jewelry, so alloys can be used to increase the strength of the metal. Additionally, many pure metals are not suitable for jewelry because they are too expensive or too difficult to work with. For example, gold is too soft in its pure form, so jewelers will often alloy it with other metals like copper and silver to make it stronger and more suitable for use in jewelry. Alloys can also be used to change the color of the metal. For example, by alloying gold with copper, jewelers can create rose gold.

Answer:

The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Explanation:

If there was a disease (as an example) that negatively effected both organisms that reproduce asexually and sexually, the organisms that reproduce asexually would have a disadvantage. Offspring of the organisms that reproduce sexually contain the genetic material of both parents. This would lead to a higher chance of the ability to adapt to any changes, or even a chance of being immune to that disease. However, offspring of the organisms that reproduce asexually are only replicates of the parent. This means that the asexually produced offspring and the parent organism could be harmed more than the sexually produced offspring and parent organism. The organism would have reduced abilities to adapt according to the changes in the enviroment.

The major disadvantage for organisms that reproduce asexually is option 4 that the offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Asexual reproduction is a type of reproduction where only a single parent is involved in creating offspring. The offspring reproduced are genetically identical to the parent. while this form of reproduction has many advantages including rapid and quick reproduction, it posses some major drawbacks as well.

As the genetic diversity is absent in asexual reproduction, adapting and surviving in the dynamic environment is tough for the offspring. Difficulty in catching up with the changing circumstances can sometimes lead to harm to upcoming species.

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
