22. What is a beneficial way ethylene affects plants; what is a negative way ?

Answers

Answer 1

Answer:

Beneficial is fruit ripening

And negative is abscission.

Explanation:

Ethylene is a plant growth regulator or phytohormone of plant. It is beneficial to plants in that it aid fruit ripening, it hasten flower opening and shedding of leaves.

Ethylene also have a negative effect and they include; Ethylene effects include: it result in loss of chlorophyll, abortion of major plants part, it lead to the stem shortening, abscission or dropping of plant parts, epinasty, and dormancy and scinence. Thus hormone can be produced when plants are injured, either mechanically or are affect by certain disease

Describe the role of fermentation in maintaining ATP and NAD+ levels

Answers

Answer:

Please find the description of the role of fermentation in the production of ATP and NAD+ levels below.

Explanation:

Fermentation is a form of anaerobic respiration in which glucose is broken down in the absence of oxygen to produce carbon dioxide and alcohol or lactic acid depending on which type of fermentation it is.

Fermentation process makes use of the electron carrier, NADH, mad oxidizes it back to NAD+. This electron acceptor molecule is strictly required in the glycolysis process. Hence, fermentation helps convert NADH to NAD+ needed by glycolysis for the production of few ATP molecules. In summary, fermentation may not directly synthesize ATP but it helps produce the molecule (NAD+) needed to synthesize it.

what component of the blood does Warfarin affect

Answers

Anticoagulants such as heparin or warfarin (also called Coumadin) slow down your body's process of making clots. Antiplatelet drugs, such as aspirin, prevent blood cells called platelets from clumping together to form a clot. When you take a blood thinner, follow directions carefully.

Answer: These drugs are often used to treat similar conditions.

Warfarin works by stopping your body from forming blood clots. It does this by blocking the formation of blood clotting factors, which are needed to make clots.

What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.

Answers

Answer: Fearful and worried posture

Explanation:

Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.

When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to  make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).

All these tell that a dog is scared and worried or feeling tense.

Answer:

Defensive Threat Posture

Explanation:

Whale eye (whites of eyes showing)

Tail down or fully tucked

Piloerection

Ears back or flatten against head

Pupils dilated

Corners of mouth pulled back

Body lowered

Body leaning backward

A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.

What are some ways another kind of natural disaster could change an environment and change the selective pressures felt by a species?

Answers

Answer:

Strong volcanic eruptions and fires can temporarily change regional weather, cooling or heating the air, changing winds, or causing rain. Volcanoes, storms, and floods can kill marine animals directly, or cause long-term problems by depositing debris and affecting the temperature and salinity of water.

Explanation:

Some ways through which natural disasters could change an environment and change the selective pressure felt by a species are volcanic eruptions, wildfires, floods, droughts, storms, acid rain, etc.

What is Species?

Species may be defined as the collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. It is the basic unit of classification and a taxonomic rank of an organism.

According to the context of this question, effective and long-lasting volcanic eruptions and fires can significantly change regional weather. Apart from this, actions like cooling or heating the air, and alterations in wind patterns and directions that typically cause rain also change an environment and change the selective pressure felt by a species.

Therefore, some ways through which natural disasters could change an environment and change the selective pressure felt by a species are volcanic eruptions, wildfires, floods, droughts, storms, acid rain, etc.

The following is the results of a genotype being "foiled" for a dihybrid cross: BS | Bs | bS | bs
Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS

Answers

Answer:

C. BbSs

Explanation:

The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.

This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.

So, the genotype must be C, BbSs

The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.

The parent's genotype will then be BbSs.

The genotype of both parents have to be heterozygous as a result of the

presence of its forms in the B and S traits. There is the presence of the

dominant (B,S) and recessive traits (bs).

The genotypes of the parent will however have both traits in them which

translates to the option C) BbSs being the most appropriate.

Answers

Answer:

c) tubes 2, 3, and 4 only

Explanation:

Cellular respiration is a metabolic process in which cells of living organisms break down organic molecules to synthesize or release energy in form of ATP. Because all cells require or need energy (ATP) for their functioning, cellular respiration is carried out by ALL LIVING ORGANISMS.

According to this question involving four test tubes that contain the following:

- Tube 1 contains water only.

- Tube 2 contains a live snail.

- Tube 3 contains a live green water plant.

- Tube 4 contains both a live green water plant and a live snail.

Cellular respiration will be carried out in the test tube that contains any living organisms. These test tubes are test tubes 2, 3 and 4 as they contain live green plants and snail.

light years across

D)

A unit of time that is equal to the amount of time it takes light to travel

from the Sun to Earth,

Answers

Answer:

B

Explanation:

The correct option should be B.

The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.

Mathematically, in astronomy,

1 astronomical unit = 150,000,000 km

But then, 1 km = 0.621371 mile

Hence,

150,000,000 km = 150,000,000 x 0.621371 miles

            ≈93,000,000 miles

Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.

The correct option is B
