Carrier proteins are used in active transport true or false

Answers

Answer 1
Answer:

Answer:

True

Explanation:

Unlike channel proteins which only transport substances through membranes passively, carrier proteins can transport ions and molecules either passively through facilitated diffusion, or via secondary active transport.

Simulated environment with equal amounts of insects seeds and fruit which flock will be able to eat the most the least and why

Answers

Answer:

This simulation is based on the experiment to examine the natural selection in birds.

Explanation:

Consider a species of birds A which eats only insects. Likewise, species of birds B and C which eats seeds only and fruits only respectively.

When there is equal amount of insects, seeds and fruits then the flock of all three species will be able to eat equal.

But, consider another species of birds D which eats all three of those foods then this species will be able to eat the most while the species eating the single type of food will end up eating the least.

Answer:

The flocks all started with 10 birds. Flock was X the most successful at feeding, so it will have the greatest number in the second generation. Flock was Z the least successful at feeding and has shrunk the most.

How many ATP and NADPH molecules are required in the C3 pathway to make one six-carbon sugar? If the synthesis of a molecule of ATP were to require four protons, would you expect that these relative requirements for ATP and NADPH could be met by noncyclic photophosphorylation in the absence of cyclic photophosphorylation?

Answers

Answer:

The correct answer is 18 ATP and 12 NADPH and noncyclic photophosphorylation can produce ATP molecule in the absence of cyclic photophosphorylation.

Explanation:

ATP and NADPH molecules are synthesized during light reaction of the photosynthesis which is utilized during the reactions of the dark phases. Dark reaction or Calvin cycle (C3 cycle) is the cyclic pathway of producing glucose triose phosphates (3C) from carbon dioxide and water. This reaction proceeds into 3 phases: carboxylation, reduction and regeneration.

First ATP and NADPH are utilized during the reduction step in the reduction of 3-phosphoglycerate to glucose-3-phosphate by the transfer of phosphate group from 6 ATP to 3-phosphoglycerate and 6 NADPH reduction as it donates an electron. Regeneration step also uses 3 ATP in conversion of G3P to RUBP molecules.  

A total of 9 ATP and 6 NADPH are utilized in producing 3C G3P molecule, So, to produce 6C sugar molecule 18 ATP AND 12 NADPH are used.

During chemiosmosis synthesis of ATP, 4 protons produce 1 molecule of ATP which could be able to generate 3 molecules of ATP for each pair of NADPH. so, noncyclic photophosphorylation or Z-scheme will be able to produce ATP in the absence of cyclic photophosphorylation.

Thus, 18 ATP and 12 NADPH and noncyclic photophosphorylation can produce ATP molecule in the absence of cyclic photophosphorylation are the correct answer.

15 points and brainliest! I need some help! What are essential amino acids? Why are they essential?

Answers

An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized de novo by the organism, and thus must be supplied in its diet. The nine amino acids humans cannot synthesize are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine.

Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine

The carbon cycle ensures that carbon is not lost. Which is another important benefit of the carbon cycle? A-The carbon cycle helps regulate Earth's temperature. B- The carbon cycle ensures that living things have a continual source of hydrogen. C- The carbon cycle helps transport nutrients in bodies of water. D- The carbon cycle ensures that there is a continual supply of water.

Answers

The right option is; B- The carbon cycle ensures that living things have a continual source of hydrogen.

The carbon cycle is a process that describes how carbon compounds moves between living organisms and their environment.  Carbon is an important element and the fundamental building block of all living organisms. The carbon cycle ensures continual availability of other elements and compounds such as hydrogen and oxygen. Carbon is mainly available in the atmosphere as carbon dioxide, and also less available as important gases, such as methane (hydrocarbon). In living organisms, all hydrogen apart from the one present in water is in form of hydrocarbons.

the distance between neptune and the sun is 30.06 au. what is this distance in millions of kilometers?

Answers

There are several important information's already given in the question. Based on those information's the answer can be easily deduced. The most important thing that one needs to know is the conversion value between au and kilometers.

1 au = 1.496e+8 kilometers
Then
30.06 au = 4.49691e+9 kilometers.

I hope the conversion is absolutely clear to you and the answer has also come to your desired help.

Explain why fungi are not classified as plants

Answers

Answer:

Fungi are not classified as plants because of the absence of photosynthetic pigment i.e. chlorophyll , with the help of chlorophyll plants can synthesize their own food in the presence of sunlight so we called them Autotrophs . Fungi can't synthesize their own food they are either parasitic or saprophytic.

Answers

These are the correct matches and theses are mentioned below:

Hypothesis- an educated guess that often precedes an experiment.

Inference- conclusion drawn from information or observations already known.

Data- facts, measurements, observations.

Interpretation- personal judgment of data.

Valid- an idea that seems to be true based on evidence or observation.

Experiment- a trial or test used to verify a hypothesis.

Assumption- an idea thought to be true without any evidence to support.

Celestial- measurement of temperature.

What is hypothesis?

Hypothesis is defined as the idea or proposal that is shown to be worked further and the main aim of hypothesis is to show the framework of the future principle. Hypothesis is only the only idea not the proper theory.

Experiment is Scientific experiment which is done by testing the particular medicine on an animal and by observing the impact of medicine on the animal as well as the reaction of the animal.

There are mainly three types of scientific experiments and these are experimental which consist of major level of scientific experimentation. The second type is Quasi- experimental and third type of experiment is non- experimental study or research.

Therefore, Hypothesis- an educated guess that often precedes an experiment.

Inference- conclusion drawn from information or observations already known.

Data- facts, measurements, observations.

Interpretation- personal judgment of data.

Valid- an idea that seems to be true based on evidence or observation.

Experiment- a trial or test used to verify a hypothesis.

Assumption- an idea thought to be true without any evidence to support.

Celestial- measurement of temperature.
