Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
Explanation:
The correct statement is C. They demonstrate how different species differ and which creature created the structure first. Anatomical characteristics observed in several species that have a common ancestor include what are known as homologous structures.
Although these structures may have diverse purposes in many creatures, their similarities suggest that they had an ancestor.
The anatomical characteristics of several creatures may be compared to find homologous structures and deduce evolutionary links.
Because diverse kinds of creatures have homologous features, it is likely that these qualities were passed down from a common ancestor.
Similarity levels and common anatomical patterns might shed light on a species' evolutionary path.

HaploidHaploidDiploidTriploidZygoteWhat is double fertilization?Double fertilization is a specific feature of angiosperms involving two male gametes and one female gamete.
In double fertilization, both the female and male gametes are haploid structures i.e. contain one set of chromosome.
One of the haploid sperm cells fertilizes an haploid egg cell, producing a diploid (2n) zygote. However, the other sperm cell fertilizes the polar nuclei, forming a triploid endosperm.
The zygote will eventually develop into the sporophyte (vegetative plant).

Help the Rossis understand how it is that Kai has NF1. Did he acquire it from them, or, was his case spontaneous? Explain your reasoning and, in your explanation, include the following terms or concepts, underline each: genotype phenotype, hom0zygous heterozygous inheritance alleles dominant recessive
Answers
Neurofibromatosis type 1, also know as NF1 is a genetic disorder that is caused by gene changes (also called mutations). The NF1 Gene is found on chromosome 17 and it carries the instructions to create a protein called NF! NF1 regulates mitosis, and works to prevent cells from growing and dividing in an uncontrolled way. The cells of individuals with NF1 divide out of control, leading to the creation of tumor. We have found that Kai has one mutation that was detected in the NF1 gene.
Kai may have NF1 Because of the parents may be a carrier The genes we inherit compose our genotype and determine the physical characteristics we possess, our phenotype. Alleles are important for the variations in which the trait can be expressed. The stronger allele is known as the dominant gene, and the weaker allele is known as the recessive gene. A phenotype is an individual's observable traits, such as height, eye color, and blood type.
The genetic contribution to the phenotype is called the genotype. The gene changes can be passed from parent to child, or they can happen on their own. If you have NF1 or NF2, your baby has a 50-percent chance (1 in 2) of inheriting it from you. heterozygous are carriers in recessive genetic disorders a person with recessive alleles but does not display trait, can pass the trait.
When there is two identical alleles of a particular gene that is h.o.m.ozygous and if there is two different alleles of a particular gene or genes, then that is heterozygous.
Neurofibromatosis kind 1, additionally recognise as NF1 is a genetic disease this is due to gene adjustments (additionally referred to as mutations).
The NF1 gene is discovered on chromosome 17 and it includes the commands to create a protein referred to as NF1 regulates mitosis, and works to save you cells from developing and dividing in an out of control way. The cells of people with NF1 divide out of control, main to the advent of tumor. We have discovered that Kai has one mutation that changed into detected withinside the NF1 gene.Kai can also additionally have NF1 Because of the mother and father can be a provider the genes we inherit compose our genotype and decide the bodily traits we possess, our phenotype.

How could we slow down or help stop ocean acidification?
Answers
Answer stop using plastic.
Explanation: Hello! My name is Hunter and I am a Marine Biologist within the state of Juno beach Fl, I work at a marine center located there and I teach people about Marine life animals and some ways to approach animals, and more. And here are some ways you can slow down or help stop ocean acidification. If you care for marine animals take the decision to use glass, wooden, bamboo, or metal etensals. This helps instead of using plastic because most plastic ends up being in the ocean. studies show that about 150 animals die a day from inhaling plastic. Second, Most plastic has acid or a type of smell like the rubber gloves at the dentist, That smell and taste can be extremely toxic and deadly for marine life animals. Third, If you are a fisher or you work on a supply boat, Make sure your oil on the boat doesn't leak, Just because you call someone and they put a net around the oil doesn't mean animals can't get under the net. Animals in the ocean are free, If you're on or work on a supply boat, Make sure to check your oil frequently. Oil leaks happen more than you think if you are not experianced! I hope this helped and how WE can slow down or reduce acdification. Have a great rest of your day or night.

What are different structures of protein?The function of protein is completely dependent on its folding. Protein can be folded into many types.
The macromolecule protein can have the following structural classification:
Primary structure: It is a linear chain of amino acids.Secondary structure: The linear chain folds to form secondary structure.Tertiary structure: it involves further folding of protein chain.Quaternaty structure: it is the spatial arrangement of the folded protein.Hemoglobin is one of the proteins that exhibits quaternary structure.

In general, the frequency of crossing over between two linked genes depends on what?
How far apart they are on the chromosome
The characteristics that the genes code for
Whether the genes are dominant or recessive
The phase of meiosis in which the crossing over occurs
Answers
Answer:
Crossovers during meiosis happen at more or less random positions along the chromosome, so the frequency of crossovers between two genes depends on the distance between them.
The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.
[tex]\huge{\color{magenta}{\fcolorbox{magenta}{black}{\huge{\color{white}{\fcolorbox{aqua}{black}{✿ᴀɴsᴡᴇʀ✿}}}}}}[/tex]
If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency. Genes that are closer together undergo fewer crossing over events and non-crossover gametes will exceed than the number of crossover gametes.
