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.

The water of a swimming pool is hypotonic to our cells. Explain in detail with evidence and reasoning why we do not swell and pop when we go for a swim.
Answer: Hello: ) ✨ It depends on the concentration of all solutes in the solution (ie, its osmolarity). A solution with low osmolarity is hypotonic and vice versa. Solutions having the same osmolarity are isotonic. Water in pools and rivers is hypotonic compared with sea water, but water from the Dead Sea is hypertonic.We do not swell and pop when we go swimming in a hypotonic swimming pool because our skin protects us from the external environment and does not let water cross into or out of our body surfaces. ... hope this helps have a great dayAssuming the water is warm enough that you don’t simply die of hypothermia, the next problem would be your skin. For reasons that still aren’t well understood, human skin starts to break down after continuous immersion in water of a few days. You’d suffer open sores and be liable to fungal and bacterial infections just from the spores on your skin, even if the water itself was perfectly sterile. The pressure of the water also reduces the circulation to your extremities and makes breathing more difficult.
Explanation:
A relative term, hypotonicity defines a solution's characteristic in relation to another solution.
What is hypotonic solution?The cytosolic fluid or the fluid found inside a cell is frequently used as the comparison solution in biology. Therefore, a solution would be considered hypotonic in biology if it contained fewer solutes than the cytosol of a cell. The semipermeable membrane is the cell membrane. What then occurs to a cell in a hypotonic environment.
Tonicity has the prefix "hyper," which denotes "more" or "excess." Consequently, a solution that contains more non-penetrating solutes than the other solution can pass through a semipermeable barrier.
Therefore, A relative term, hypotonicity defines a solution's characteristic in relation to another solution.

Scientists have discovered a colony of potential organisms on the Planet Moby and named them "Maxoids." Read the information below that scientists have gathered on Maxoids and decide whether Maxoids are living or nonliving things. Explain how you came to this conclusion.
Through testing and observation, scientists have recorded the following characteristics of Maxoids. Maxoids reproduce via sexual reproduction. One parent carries the Maxoid eggs for 12 weeks before they hatch. After hatching, juvenile Maxoids continue to grow for seven months. To acquire energy for growth, Maxoids consume a peculiar liquid substance native to the planet Moby. The Maxoids' cells use this energy, as well as large amounts of water, to carry out important functions. The Maxoids are sensitive to changes in internal temperature. Sometimes they dig holes and lay in them to cool down if they get too warm.
The Maxoids are living things because they possess the characteristics of living things.
What are living things?Living things are things which have life in them.
Living things are identified by the characteristics which make them living.
The characteristics of living things include:
Movement - living things are able to move all or parts of their bodyRespiration - living things are able to break down food substances to produce energyNutrition - living things are able to take in food substancesIrritability - living things are able to respond to changes around themGrowth - living things are able to increase in size and massExcretion - living things are able to remove waste substances from their bodiesReproduction - living things are able to produce new ones of their kindConsidering the Maxoids;

What is the relationship between guard cells and stomata in plants?
Guard cells open and close the stomata to regulate the rate of transpiration.
Guard cells protect the stomata from insects and other pests.
Guard cells store carbon dioxide for later use by the stomata.
Guard cells absorb light energy from the Sun for use by the stomata.
Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis . Critical in this process is the stoma.
Answer:
Guard cells open and close the stomata to regulate the rate of transpiration.
