Why are ribosomes necessary for both Prokaryotic and eukaryotic cells to function properly?
Answer:
ribosomes are found in both cells
Explanation:
Ribosomes are special because they are found in both prokaryotes and eukaryotes. While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins. ... The attached ribosomes make proteins that will be used inside the cell and proteins made for export out of the cell

Which of the possible examples below would most likely lead to a change in the cell theory? A Scientists find life on Mars that is not made of cells. BScientists identify a cell organelle that practices the process of photosynthesis. C Scientists determine that an organism is living if it is made of twenty structurally-identical cells. D Scientists gather life from a volcano that is composed of cells which are very different from humans.
Answer: Probably B?
Explanation:
The possible examples below would most likely lead to a change in the cell theory: Scientists discover life on Mars that is not made of cells, i.e., option A, despite the fact that the cell theory states that all living organisms are made of cells.
What is the significance of the cell and its importance?Cell theory explains that life is made up of cells, but If scientists were to discover life on Mars that did not fit this definition, it would challenge the current understanding of the cell theory and the discovery of life on Mars that is not composed of cells would indicate that the cell theory is not universally applicable.
Hence, the possible examples below would most likely lead to a change in the cell theory: Scientists discover life on Mars that is not made of cells, i.e., option A, despite the fact that the cell theory states that all living organisms are made of cells.

A town plans to clear a patch of forest to make a road wider. What possible changes should the town take into account?
Answer:
Remove vegetation and little damage to the forest.
Explanation:
The town has to remove all vegetation that is present along the road in order to make road wider but the people of town has to make sure that limited damage has to be done to the forest and organisms that lives in that forest ecosystem. Avoid unnecessarily cutting of trees and and add that side of forest to the road which has no or less number of trees so that trees can be saved from harm.

natural selectiongenetic variationenvironmental fitnessgene mutationsAnswer:
genetic variation
Explanation:
Whenever migration occurs between two populations, there is genetic flow going on. Genetic flow is an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.
Genetic flow acts homogenizing the allelic frequencies between the two populations, and it might introduce variability into the new one.
For genetic flow to be possible, there needs not only the movement of the genes from one population to the other but also the reproduction process on the new population. Hence, it involves an interaction between the dispersion pattern and the reproductive system.
The bigger the difference in allelic frequencies between populations is, the bigger is the effect of the genetic flow.

Problem 3: Unfortunately Punnett Squares are not always for finding out the best parts about parenting. They are often, as you will see in the next few lessons, often used to determine the probability of a disease being passed on to a child. We'll have you try one and see what that looks like. One such disease is Cystic Fibrosis. Let's assume both parents are heterozygous for Cystic Fibrosis. That means both parents carry the recessive gene for the disease, but because of the dominant genes they have, they don't have it. However, they want to know if they try to have a child, what the chances of the child would be for having Cystic Fibrosis?
Answer:
eh
Explanation:
A small and this of spring will be impacted, and this offspring will be normal. Therefore, it is clear that there is a 25% risk that the progeny may be impacted. Due to the fact that one in four people have cystic fibrosis, we can thus state that the likelihood that either of these two people's offspring will be affected is four to one. Therefore, this will be our last arm.
What is cystic fibrosis?The lungs, digestive system, and other body organs suffer severe damage as a result of the genetic condition cystic fibrosis (CF).
Mucus, perspiration, and digestive juice production are all impacted by cystic fibrosis. Normally thin and slick, they released fluids. However, CF patients' secretions are thick and sticky due to a gene abnormality. The secretions clog up tubes, ducts, and passages rather than functioning as lubricants, notably in the pancreas and lungs.
People with cystic fibrosis can normally go to school and work, but the disease is progressive and necessitates daily care. In many cases, their quality of life is higher than it was for those with CF in the past. CF patients may now live longer because to advancements in diagnosis and therapy.

A widow's peak hairline (W) is dominant to straight hairline (w). Cross a heterozygous widow's
peak hairline person with a straight hairline person. What are the genotypic and phenotypic
ratios of their offspring
Answer:
Use a punnett square! I'll attach an example.
Genotype - Genetic constitution of dominant and recessive traits inherited from parents. BB, Bb, & bb can be used to represent these.
Phenotype - Observable. If a dominant trait is present, it shows as the phenotype. For example, brown hair is dominant to blonde hair. A person with a BB or Bb genotype will have brown hair, but a person with a bb genotype will have blonde hair.
Statistically, they have a 50% chance of a child with a widow's peak, and a 50% chance of a child with a straight hairline.
The genotypic and phenotypic ratios of their offspring are 50% and 50% ratio of the child.
What are the heterozygous ?
The heterozygous are the condition where you have inherited different forms of a particular gene from each of your biological parents. By different shapes we generally mean that there are different parts of the gene where the sequence is different.
Genotype - Genetic charter of dominant and recessive developments inherited from parents. BB, Bb, & bb may be used to symbolize these.Phenotype - Observable. If a dominant trait is present, it indicates because the phenotype. For example, brown hair is dominant to blonde hair. A individual with a BB or Bb genotype may have brown hair, however someone with a bb genotype may have blonde hair.Statistically, they've a 50% risk of a toddler with a widow's peak, and a 50% risk of a toddler with a instantly hairline.
