How can a mutation give adults the the ability to digest milk? ​

Answers

A single point mutation in the DNA near the lactase gene changes the cytosine (C) nucleotide to a thymine (T). Individuals with the thymine (T) nucleotide are lactose tolerant and can digest the milk products in adulthood.

In seedcracker finches on a remote island, birds are found with varying bill sizes. Those with larger bills (on average) specialize in cracking hard, thick-walled seeds. Birds with smaller bills (on average) feed on seeds with softer seed coats. If ongoing climate change results in the most of the seeds in the area becoming thich-walled, predict the outcome on the population of seedcracker finches. Select ALL that apply

Answers

Answer:answer is b and d

Explanation:

Birds with larger bills (on average) specialize in cracking hard, thick-walled seeds and Birds with smaller bills (on average) feed on seeds with softer seed coats, but if climate change results in most of the seeds in the area becoming thick-walled, then only birds with larger bills will survive.

What is the natural selection in the case of finches?

Natural selection selects the best and fittest individuals so that the population or species can grow further, as in this case, where both types of finches are present, but due to climate change, only the seeds with thick walls survived, and the birds that can eat these will survive, while the rest will be removed from the environment.

Hence, birds with larger bills (on average) specialize in cracking hard, thick-walled seeds and Birds with smaller bills (on average) feed on seeds with softer seed coats, but if climate change results in most of the seeds in the area becoming thick-walled, then only birds with larger bills will survive.

3- In gene expression, DNA is used as a template to make _______, which is then used as a template to make a polypeptide.
4- In the process of _______, DNA can be rearranged, which contributes to the genetic diversity of the species.
5- What are the differences between the structures of DNA and RNA?
6- How can the central dogma help us understand the process by which DNA is turned into protein? What are the two steps involved in the process of gene expression?
7- Why are replication and recombination two important roles of DNA?

Answers

Answer:

1.hydrogen

2.template

3.mRNA

4.recombination

5.DNA and RNA are both made up of nucleotides. RNA is comprised of adenine, uracil, guanine, and cytosine. DNA is made up of adenine, thymine, guanine, and cytosine. DNA is a double-stranded chain of nucleotides comprised of base pairs that form a double helix. RNA is often a single-stranded chain of nucleotides.

6.The central dogma states that DNA contains the genetic code needed to make proteins—a process known as gene expression. Transcription and translation are the two steps involved in gene expression. In transcription, the DNA code is turned into RNA. In translation, the RNA sequence provides instructions to the cellular machinery to manufacture polypeptides, which become proteins.

7.Replication is the duplication of DNA, and it is important because, in cell division, each daughter cell must contain an exact copy of the original cell's DNA, since DNA contains the instructions required to make all of the cell's tissues. Recombination is the natural process for genetic sequences in a chromosome or between chromosomes to exchange genetic information. Recombination is important in nature because it produces genetic variations that may be preserved because of natural selection. Recombination also can be used in the laboratory to combine the genetic code of two different organisms.

Jena is using a drawing to show how the greenhouse effect works. She uses arrows to depict the movement of
radiation from the sun, through space, and through the Earth system.
Which arrows show how radiation interacts with the greenhouse gases?
A) the arrows from the sun to the Earth's surface and from the Earth's surface to space
B) the arrows from the sun to the atmosphere and from the atmosphere to space
C)the arrows from the Earth's surface to the atmosphere and from the atmosphere to the Earth's
surface
D)the arrows from the sun to the Earth's surface and from the Earth's surface to the underlying
rocks and soil

Answers

Answer:

The correct answer is - C. the arrows from the Earth's surface to the atmosphere and from the atmosphere to the Earth's surface.

Explanation:

Interaction between radiation and greenhouse gases can be demonstrated or represented by a model which shows how the radiation from different sources of the earth's surface is released in the atmosphere and how the radiation comes to the earth's surface from the atmosphere of the earth.

The radiation trapped by the greenhouse gases and more infrared radiation will be absorbed and emitted back toward Earth's surface, which affects and show more greenhouse effect.

1 . What happens in the population if the mutation phenotype is helpful

2. Why does that happen for that population that has a helpful phenotype?

3. How does this mutation continue to exist in a population?

Answers

Answer:

1. The population will increase as they're better adapted to their environment and have a higher survival rate due to this helpful phenotype.

2. This happens to the population because this helpful phenotype might lead to less exposure to predation in which leads to a better survival fitness for the organism.

3. This mutation continues to exist as the organisms continue to successfully reproduce into the population due to being able to survive for longer.

(Heredity)Discussion Topic
In some cases, people who test positive for genetic testing can receive
preventive treatments. For example, people who test positive for the breast
cancer genes BRCA1 and BRCA2 can have a preventive mastectomy (breast
removal surgery) before they develop the disease. In other cases, no preventive
treatments are available, but frequent monitoring can help detect a disease
earlier, when it's more easily treated.
What ethical or professional concerns does a health-care professional need to
address when he or she has a patient who wants to prematurely treat a genetic
disease? Do you think genetic testing should be part of normal preventive
healthcare? Why or why not?

Answers

Answer:

Discrimination occurs due to presence of "inferior" genes

Explanation:

Discrimination occurs due to presence of "inferior" genes is the ethical or professional concerns that the health-care professional need to  address when he or she has a patient who wants to prematurely treat a genetic  disease. Yes, I think that genetic testing should be a part of normal preventive healthcare because this genetic testing provides information about inheritable diseases. This testing can avoid future diseases by treating it before it causes severe damage to the body.

Answer:
this is an alternate answer that is simply paraphrased from the first answer (to prevent suspicion of cheating)
Explanation:

Discrimination arises owing to the presence of "inferior" genes, which is the ethical or professional dilemma that a health-care provider must face when he or she has a patient who wishes to treat a hereditary condition early. Yes, I agree that genetic testing ought to be a standard component of preventive healthcare because it informs us about inheritable disorders. By treating diseases before they seriously harm the body, this testing can prevent them in the future.

cual es el proceso de la fotosintesis

Answers

Answer:

fotosintesis es el conjunto de reacciones gracias a las cuales las plantas verdes a partir de la energía luminosa transforman el agua y el anhidrido carbónico en oxígeno y sustancias orgánicas ricas en energía.

Sin el proceso de la fotosintesis no sería posible la presencia del oxigeno en la atmosfera. Son muchos los seres vivos que dependen del oxigeno que se libera durante la fotosintesis. Y no solo del oxigeno desprendido sino que la mayor parte de estructuras de los seres vivos para su desarrollo necesitan los productos orgánicos formados durante la fotosintesis junto a materia inorgánica del propio media ambiente. Por tanto puede decirse que la materia que forma a los seres vivos está formada por materia organica.

Explanation:

It make the comparison between humans and chimps because the two species are so closely related to each other. Humans an chimps evolved from a single ancestor species about six or seven million years ago. Humans and chimps gradually evolved from a common ancestor due to environmental conditions that change their DNA which passed from generation to generation and bring changes in their shape and appearance as well.
