Answer:
Commensalism is a symbiotic relationship in which one species benefits while the other is not affected.
Explanation:
The organism of the ecosystem like the plants and the animals along with the microorganisms are connected and interlinked with one another through the ecological relationship. The relation could be positive, negative or neutral.
What is symbiotic relation?Symbiosis is an ecological relationship in which the organisms lives together and they both or a single organism is benefitted from the other.A symbiotic relationship in the ecosystem can be positive, neutral or negative and is of various types like commensalism, competition and parasitism.If the organism is removed from the symbiotic relationship then the factors like the shelter, food, locomotion etc. of the other organism can be affected adversely.Thus, symbiosis is important for the ecosystem.

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:
I think it is all the answers except for What types of organisms are preying on the mosquitoes in their new habitats? this is because when a new species comes to an area it does not have anything to prey on it
The pH of a solution is a measure of how acidic or basic it is. The greater the pH, the more basic the solution is. Corals and other marine invertebrates require less energy to make their exoskeletons and shells when ocean water is slightly basic. As carbon dioxide concentrations in Earth’s atmosphere rise, ocean water absorbs carbon dioxide and becomes more acidic. This process is called ocean acidification. How do you think ocean acidification will affect the coral reef?
Explanation:
Because coral reefs have limestone (calcium carbonate), the coral reefs will be greatly affected. The increase in hydrogen ions in the ocean will corrode the coral reef, making it inhabitable for species. This will affect the crabs that get their food and the community that lives within in it. Making countless of species to loose their lives and their way if living.

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'Plant Growth

A freckled man marries a woman without freckles. They have four children, two with freckles, and two without freckles. What are the genotypes of all these people?
Answer:
The genotype of the father: Ff
The genotype of the mother: ff
The genotype of the two children without freckles: ff
The genotype of the two children with freckles: Ff
Explanation:
Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles. Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype. In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.
A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
What is the significance of the freckle trait?There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).
Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
