How many electrons must get passed down the Electron Transport Chain before energy is generated?

Answers

Answer 1

Answer:

4 electrons

Explanation:

Electron transport chain is defined as the series of process in which electron transfer takes place across a membrane. It is consists of enzymes, peptides, and other molecules.

There are 4 electrons that passed down the Electron Transport Chain before energy is generated. These Four electrons further reduce each molecule of oxygen. Oxygen binds with free proton and form water and move across the membrane to form ATP.

Hence, the correct answer is "4 electrons".

Which two of the following correctly describe what a gene is?

A packet of genetic information that can be passed down from one generation to the next
A DNA molecule
The entire collection of genetic information in a given species
A section of DNA that provides instructions for building a specific protein
I'm not sure

Answers

Answer:

A section of DNA that provides instructions for building a specific protein and A packet of genetic information that can be passed down from one generation to the next

Explanation:

A DNA molecule is not a gene, it is a nucleotide. The entire collection of genetic information in a given species results isn't a gene although many genes comprise what is the genome.  Given that those two answers are not what genes are, the other two options are correct.

Carson divided 40 unripe bananas evenly among eight paper bags and sealed the bags. He poked 20 small holes in four of the bags and left the other four without holes. He kept the bags at room temperature for three days. Then, Carson opened the bags and counted the number of brown spots on each banana. He compared the average number of brown spots on bananas from bags with holes to the average number of brown spots on bananas from bags without holes.Identify the question that Carson's experiment can best answer.

Answers

Answer:

See the answer below

Explanation:

From the illustration of the experiment, the question that Carson can best answer  is that "Do bananas develop more brown spots if they are kept in bags with holes  compared to bags without holes?"

The independent variable in the experiment is the hole poked in the bags while the dependent variable is the number of brown spots on each banana. The difference between the subjects is the hole poked in the bags, hence, any difference in the number of brown spots between bananas in the bags with holes and those in the bags without holes can be attributed to the hole poked in the bags.

Therefore, the question that can be answered from the experiment is to see if poking holes in bags make bananas to develop more brown spots compared to bags without holes.

The chemical reaction equation of photosyntesis is shown here:

What information is not given in this equation.

A)It does not show if the reaction is reversible or not reversible.

B)It does not show the reactants needed for the reaction.

C)It does not show that photosynthesis consists of many separate steps.

D)It does not show the number of molecules required to produce glucose.

Answers

Answer:

C

Explanation:

C appears to be the best answer but I think a better answer would be that it didn't include another product which is oxygen. So unless it is late and my brain is not function, I would say that should be the answer. But otherwise, since it is not there, C is the best one I think.

The chemical reaction equation of photosynthesis is shown here:

6CO2 + 6H2O → C6H12O6, C)It does not show that photosynthesis consists of many separate steps. Thus option "C" is correct.

What is photosynthesis?

The chemical reaction of photosynthesis is given as follows;

6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)

Therefore, six molecules of gaseous carbon dioxide (CO₂) combine with six molecules of liquid water (H₂O) in the presence of energy from Sunlight  to produce  one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)

The 6O₂ is the gaseous oxygen produced as a byproduct of photosynthesis

Which would have most likely stopped Mendel from finding a pattern in his results?
O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring​

Answers

Answer:

A. If seed shape did not have a clearly recessive form

Explanation:

To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.

For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.

Explain the importance
of decomposers to the overall
biogeochemical cycle.

Answers

Answer: Decomposers plan an important role in the biogeochemical cycling for nutrients in the environment as they are responsible for the breakdown and return of nutrients back to the environment in their native state.

Decomposers are essential for the biogeochemical cycle as they facilitate the recycling of nutrients, provide energy for other organisms, and help maintain the health and balance of ecosystems by Breaking down organic matter, Recycling nutrients, Energy flow and Detoxification.

Without decomposers, organic matter would accumulate, nutrients would become locked up, and energy flow within ecosystems would be disrupted.

Decomposers play a crucial role in the overall biogeochemical cycle. Here's why they are important:


Breaking down organic matter: Decomposers, such as bacteria and fungi, break down dead plants, animals, and other organic materials into simpler compounds. They do this through the process of decomposition, where they release enzymes that break down complex molecules into smaller, more manageable forms.

Recycling nutrients: By decomposing organic matter, decomposers release essential nutrients back into the ecosystem. These nutrients, such as carbon, nitrogen, phosphorus, and sulfur, are then made available for uptake by plants and other organisms. This recycling of nutrients is vital for maintaining the balance and productivity of ecosystems.

Energy flow: Decomposers also play a crucial role in energy flow within ecosystems. When they break down organic matter, they release energy in the form of heat. This energy can then be used by other organisms in the ecosystem, such as primary consumers (herbivores) and secondary consumers (carnivores), to carry out their life processes.

Detoxification: Decomposers are capable of breaking down and detoxifying harmful substances and pollutants in the environment. For example, certain bacteria can break down pesticides and other chemical pollutants, helping to reduce their negative impact on the ecosystem.

The eggs of a cone bearing plant:

receive pollen from the wind

Answers

Answer:

Receive pollen from the wind.

Explanation:

The sperm of the male cone floats through the air and lands on the scale of the female cone. Sperm cells move through the pollen tube of the female cone and one of them fertilized an egg cell which eventually turns into a seed.

Answer:

The eggs of a cone bearing plant receive sperm through the development of tubes.

Explanation:

Cone-bearing plants have two types of cones: female cones and male cones. Reproduction begins when one of the pollen grains from inside a pollen sac on the male cone floats through the air to the scale of a female cone. A pollen tube then grows from the pollen grain toward the female ovule. Sperm cells move through the pollen tube and one of them fertilizes an egg cell, which then develops into a seed. The winged seed floats to the ground and begins to germinate. As the top of the seedling reaches for light, the hypocotyl straightens and the cotyledons spread out.
