How is co2 converted to glucose?

Answers

Answer:

Photosynthesis

Explanation:

Atmospheric carbon dioxide is converted to glucose during the Calvin-Benson cycle. This requires the overall reduction of CO2, using the electrons available from the oxidation of NADPH. Thus the dark reactions represent a redox pathway. NADPH is oxidized to NADP+ and CO2 is reduced to glucose.

Please Help! What molecules need to travel through ATP synthase to help it create ATP?

The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.

What is RNA polymerase?

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.

Your laptop was left on all night without being charged. When you wake up, the battery is dead. What happened to the battery's energy? * 5 points It was destroyed It was transformed to light, heat and sound energy. It leaked out of the laptop's battery. It was given off to the surrounding air as radiation.

Answers

Answer:

It was transformed to light, heat and sound energy.

Explanation:

Energy in a battery is used act as chemical energy that gives power to an electronic device along wires.

Energy of laptops battery transformed to light, heat and sound energy when left overnight without being charged. Light energy can be seen when laptop left turned on, laptops also creates sounds due to intense vibrations as the system is turned on and chemical energy is utilized, and when chemical energy converted into heat energy and the system get heat up.

Hence, the correct answer is "It was transformed to light, heat and sound energy."

Geckos are a type of small lizard that live in tropical areas. Geckos are often eaten by birds, snakes and larger lizards so they need to blend into their surroundings. In one area, scientists had always found brown and green geckos that blended in with the grass and the leaves on the ground. Over time, though they found yellow geckos in the same population. Three students were talking about why there were yellow geckos. Ciena thought that the change came from a mutation in the population. Tibor thought the change came from the environment. Sasha though that Ciena and Tibor were both right. Who do you agree with and why do you think that?​

Answers

Answer:

Not going to say this is right but, I think that Tibor is correct because if the land has changed more over time then the yellow ones have adapted to the new living conditions while the green one have found ways to live in that environment.

If a rock falls and kills 10 individuals from a population of 100 plants of the same species and the frequency of alleles changes, does the population evolve instantly from that stochastic event? Can it be said that Natural Selection is at work in this case? And how does the Synthetic Theory of Evolution help answer this question?

Answers

Answer:

Explanation:

This question seeks to test the knowledge of the modern synthetic theory of evolution. This theory describes evolution as the changes occurring in the allele frequency within a population of the same specie. Hence, the following questions derived from the question can be answered as thus

1) Does the population evolve instantly from that stochastic event?

YES. This is because the frequency of the allele changed.

2) Can it be said that Natural Selection is at work in this case?

YES. The synthetic theory of evolution derives great "evidence" from natural selection because the allele frequency is believed to have changed because of the environmental impact (the rock) and that the next generation will adapt better to such an environment.

3) How does the Synthetic Theory of Evolution help answer this question?

Previously, evolution was believed to occur over several generation which ultimately lead to some phenotypic changes as a result of adaptive changes in the genes. This old description of evolution would have made one arrive at a wrong answer if one does not consider the modern synthetic theory of evolution which talks about instant evolution from allele frequency (as was described in the question).

15. Briefly explain how the gel (or DNA fingerprint) is made after DNA has been amplified.

Answers

Answer:

Like the fingerprints that came into use by detectives and police labs during the 1930s, each person has a unique DNA fingerprint. Unlike a conventional fingerprint that occurs only on the fingertips and can be altered by surgery, a DNA fingerprint is the same for every cell, tissue, and organ of a person. It cannot be altered by any known treatment. Consequently, DNA fingerprinting is rapidly becoming the primary method for identifying and distinguishing among individual human beings. DNA fingerprints are also useful in several applications of human health care research and for diagnosis of inherited disorders. DNA fingerprinting is often used in the justice system to link suspects to biological evidence and solve paternity cases.

Explanation:

DNA sample: A DNA sample that will be examined must first be gathered. DNA extraction: Using the lysis process, DNA is then extracted from the sample.

What is DNA fingerprint?

Restrictions endonucleases:The DNA fragment is cut at a particular place by a specific restriction enzyme.

Alec Jeffrey, a British biologist, created the DNA fingerprinting technique in 1984 after noticing that some highly variable DNA sequences, or minisatellites, that are repeated inside genes but do not affect their activities.

In DNA fingerprinting, a gel-like fluid is used to distinguish between DNA molecules that move at various speeds. A DNA molecule that is huge moves slowly, whereas a DNA molecule that is little moves quickly.

Therefore, DNA molecules are divided in gel electrophoresis according to size. When DNA molecules are divided into distinct sizes, bands of DNA are created.

Describe a situation in which being able to drink milk would give an individual an advantage with respect to survival and reproduction.

Answers

Answer/Explanation:

A family has a farm in which they grow crops and keep cows. During a particularly harsh winter, the crops failed to grow as well as they normally do. This means that their food supply was limited.

However, they also have cows, and cows produce milk. If this family were able to drink milk, they could get some nutrition from the milk. This means they are less likely to succumb to malnutrition and disease, and are more likely to survive and reproduce.
