Hibernation and having heavy fur coats are adaptations of animals in the taiga biome. Therefore, option A is correct.
What is adaptation?"The process by which a species or an organism steadily improves its acclimation to its environment is defined as adaptation." The behavioral or physical characteristics of an animal that improve its ability to thrive in its ecosystem are referred to as adaptation.
Animals can save themselves from predators and extreme weather by adapting. various birds may conceal themselves under long grass, while weeds, insects, and other creatures can change their color to blend in. Predators find it difficult to locate them in search of food a result.
Hibernation and having heavy fur coats are adaptations of animals in the taiga biome because it provides them heat in the cold weather. Therefore, option A is correct.

In the United States, there has been an increase in the number of people infected by mosquito spread diseas that were previously found only in countries south of the United States. Scientists want to investigate the cause of the increase in mosquito spread diseases. Scientists have predicted that the mosquitos carrying disease have moved further north as global temperatures have increased. Which questions would help investigate how the new mosquitoes are affecting the ecosystems of the United States ? Select all that apply. AHow much money has been spent to fight the diseases caused by these mosquitoes across the globe? B. How have the food webs in the United States changed as a result of the new mosquitoes? the natural predators to the mosquitoes also migrated north? What types of organisms are preying on the mosquitoes in their new habitats? E Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems
Answer:
What types of organisms are preying on the mosquitoes in their new habitats?

Explanation:
Answer: RNA or DNA
Explanation:
Which principle allows us to assign dates to events on the geologic time scale?
faunal succession
extinction
radioactive decay
relative dating
The principle that allows us to assign dates to events on the geologic time scale is radioactive decay. Therefore, option (C) is correct.
What is radioactive decay?This theory is based on the observation that certain isotopes of elements are inherently unstable and, as a result, decay over time, giving rise to the formation of new isotopes or elements. Scientists are able to determine the age of a sample by measuring the ratio of parent to daughter isotopes in the sample. This, in turn, enables them to assign dates to events on the geologic time scale.
The method of determining the age of rocks, minerals, and other geological materials is known as radiometric dating, and it is utilized extensively in the field of geology as well as in other earth sciences.

We discovered that both carbon dioxide and methane have been increasing in earths atmosphere. What ideas do you have about why this might be happening? What could be causing earths atmosphere to change?
Answer:
Due to human activities.
Explanation:
This change in the concentration of carbondioxide and methane gas is happening due to human activities because human used fossil fuels which can be burn in the engines of vehicles that releases carbondioxide gas in the atmosphere. Humans are responsible for the change of atmosphere which leads to change in the climate all over the world. Methane gas is also released by human activities such as using methane for cooking food.

Tell me a brief summary of what happens in meiosis
**will mark brainliest**
Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,
Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.
_____________________________________[tex]\huge{\text{Why is Meiosis Important?}}[/tex]Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.
It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:
During the prophase of meiosis 1, crossing over of genetic material between the homologous maternal and paternal chromosomes takes place which causes exchange of DNA fragments between the chromosome resulting is genetic diversity.During the anaphase of the first meiotic division, there is random distribution of maternal and paternal homologous chromosomes among the daughter cells which are produced as a result of meiotic division._____________________________________Best Regards,'Borz'Which statement best describes evolution?

Answer:
Inherited traits are passed down to offspring from parents through their genes. Inherited traits are things that are genetic and with an animal from birth. Both of their parents pass these traits to them, and they become a mix of their parents. Hair color, eye color, fur patterns are all examples of inherited traits.

Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to different colors of light. The instructions for creating the type of opsin sensitive to red light are found on a gene known as OPN1LW, which is on the X chromosome. A genetic mutation in the OPN1LW gene can lead to a form of color blindness that affects a person's ability to detect red light. However, women have two copies of the X chromosome, and they have normal color vision if only one copy contains the mutation. Why do women who carry one copy of the mutated gene still have normal color vision?
Answer:
Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.
Explanation:
Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.
In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.

Question: How does a region’s latitude impact its climate? What role does the sun play on an area’s climate?
Answer:
Places with latitudes closer to the Equator have hotter climates. Places with latitudes closer to the Poles have colder climates. This happens because the Sun's rays hit them more or less directly.
The Sun powers life on Earth; it helps keep the planet warm enough for us to survive.
