Not to be mean but it’s kind bad and good but u said be honest basically so I did bye have a nice day
Answer:
Organisms use various strategies and adaptations to regulate body temperature and metabolism. The organisms control the exchange of heat by various ways which include physiological, behavioural means and by insulation.
The factors which play most important role in the heat exchange regulation between environment and organism are as follows:
- effective temperature difference between organism and environment
- Exposed surface area
- Evaporatory and circulatory changes
<u>Insulation</u> :Another most common method used for heat exchange.Animals who have furs,feathers and fat layers which play significant role in insulation. They are very much important because they reduce heat exchange amount between environment and organism. The most common example is of Cats. They used to curl up their bodies when they want to sleep in cold environment, they tuck their bodies in their paws and legs, and they wasp their tails around their bodies. When organism uses the food and oxygen the body temperature begins to increase, this method is known as metabolic heat production.
A. cells because, cells<span> are the most basic building units of life, all living things are composed of </span>cells<span>, and new </span>cells<span> are made from pre-existing </span>cells<span>, which divide into two. A structural or functional unit in a </span>cell<span> that is constructed from several macromolecules bonded together.
Hope this helps you in your question friend !!!^_~!!!</span>
Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
Explanation:
Sympatric speciation is an event/situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e do not live in geographical isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory to yield new species or offsprings.
This sexual selection then results in generations of offsprings that are genetically different from the rest of the same species due to uneven gene flow or disruption of alleles among the population of same species.
Thus, only option B is true.
