Stomata are tiny openings found in plant leaves. Specialized cells known as guard cells surround the stomata and open and close the openings. When it is very hot, plants may close their stomata to prevent water loss. When plants close their stomata, what else is affected?
Group of answer choices

Plants cannot take in water from the air.

Plants cannot release glucose made in photosynthesis.

Plants cannot take in the carbon dioxide they need for photosynthesis.

Plants cannot take in the sunlight they need for photosynthesis.

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.

I believe that you can assume the 1st one, but you can't really assume that they have more unhealthy people than healthy. You don't have any numbers to prove that.

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).

Answer:

Potassium or sodium hydroxide (KOH or NaOH) react with triglycerides to form soap (the process is called saponification, the reaction of a strong alkali with fats and oils). Soap is alkaline in nature and is an effective cleansing agent. It is a useful mild antiseptic and can treat heavy metal poisoning.

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.

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."

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

Explanation:

That's the answer but not all of it just pick out the actual answer.

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.

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.

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.

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.
