What type of mutation is albinism

QUESTION POSTED AT 23/09/2019 - 03:10 AM

Answered by answersmine AT 23/09/2019 - 03:10 AM

Albinism is caused by a mutation in one of several genes. Each of these genes provides instructions for making one of several proteins involved in the production of melanin. Melanin is produced by cells called melanocytes, which are found in your skin and eyes. A mutation may result in no melanin at all or a significant decline in the amount of melanin.

Name two types of evidence scientists use to support the theory of evolution. Give an example of one and describe how it shows that life changes over time.

Darwins's theory of natural selection is an evidence of evolution by acquiring characters that make survival of an organism feasible in a typical environment. 
Fossils records are used to support this theory, by figuring out the common ancestry of different species and different traits that have evolved in them with time.
Embryology is also used as an evidence which shows common origin of the organisms. Other evidences are geographic distributions and homologous structures of the living organisms.

Urgent!!!!! How can a mutation benefit an organism and its descendants? Provide an example.

A mutation can allow a organism to adapt to the environment and example can be the case of the peppered moth which has two variations a white colored one and a black colored one. The white colored ones were able to survive better that the darker ones because of how they were able to camouflage with the lichen located in the trees. However, after a while smoke particles that were released by industries darkened the trunk of the trees making the white moths visible and allowing the darker colored ones to survive. Another example can be on how organism can be resistant to bacteria this allows the animal to survive and reproduce offspring with the same mutation. I hope this helps...

Explain what type of logging would most likely necessitate reforestation afterwards.

Clear-cutting logging would be more likely to necessitate reforestation afterwards than selective cutting. Clear-cutting removes all trees in an area and results in more significant environmental damage, making it more difficult for the trees to regrow naturally. With selective cutting only some of the trees are harvested, so the overall ecosystem is preserved which makes it more likely that trees will be able to regrow naturally.

Sophia is observing slides under a microscope while adjusting its mirror so that a circle of light can be seen. Which type of microscope is she using? electron microscope compound light microscope scanning electron microscope

Answer:

The correct answer is the compound light microscope.

Explanation:

A compound light microscope comes with two or more lens and it has its own light source. There are objective lenses in a nose piece close to the specimen and ocular lenses in the binocular eyepieces.

A compound light microscope is comparatively small, so it’s easy to use and store, and it has its own light source.

Compound light microscopes reveal very fine details in slides because of their multiple lenses.

Thus, the correct answer is the compound light microscope.

Explain how a change in the sequence of nitrogen bases in a dna molecule could result in a gene mutation

Well, the order and set processes of the nitrogen bases has dominance over the order of the amino acids in the protein. If the bases are altered or mutated, then the amino acids that theseems nitrogen bases code for, are changed. This leads to a different set of amino acids, and therefore a different protein. A different protein is composed, and then the gene containing this different protein will also be different. This has a greater overall impact on some genes than others, depending on which part of the DNA polymer/polymerase is mutated

As the concentration of potassium is higher inside the cell, no energy should be required to transport it outside, but the involvement of the channels for this transport signifies the involvement of a facilitated diffusion of the potassium ions, down the concentration gradient, with the help of the channel proteins.

An organism that reproduces using binary fission, a type of asexual reproduction, creates an identical copy of a cell when A. the cell's DNA replicates and the cell divides, giving each cell an identical copy of DNA. B. part of the cell breaks off and a completely new strand of DNA is created. C. the DNA strand breaks and the cell divides, giving each new cell half of the DNA. D. the cell's cytoplasm spontaneously creates a new strand of DNA and the cell divides.

Answer:

A.

the cell's DNA replicates and the cell divides, giving each cell an identical copy of DNA.

Explanation:

An organism that reproduces using binary fission, a type of asexual reproduction, creates an identical copy of a cell when the cell's DNA replicates and the cell divides, giving each cell an identical copy of DNA. In order for the two cells to be identical, they would need the same DNA, which would result when the DNA strand is replicated.

If analogous structures are often examples of convergent evolution what types of structures would likely be examples of divergent evolution

Answer:

The correct answer would be homologous organs.

Homologous organs refer to the set of organs or body structure which share common ancestry or share the same internal structure but perform a different function.

They evolve as a result of divergent evolution, that is, they evolve to perform different functions as a result of adaptation to the different environment.

For example, the forelimb of horses, the hand of a human, flippers of the whale, the wing of a bird, wing of bat et cetera are made up of same sets of bones, however, they perform different functions.
