What is Krebs cycle?

The Krebs cycle is a metabolic cycle which is part of the respiration process. Is necessary to process the glucose of the food. It starts with glucose then through acetyl Coenzyme, and then in citrate, the cycle starts.

Trough 7 chemical reactions, Krebs cycle will be produced some other chemical substances but the most important is that is going to form ATP, the energetic coin in living things.

FADH2 and NADH is used in the electron transport chain, the next step in the process, to form hydrogen ions.

How does the process of hydration cause chemical weathering?

A.
Water reacts with iron minerals in rock to form rust.
B.
Moving water transports sediment from rock.
C.
Increased density adds pressure to the molecules in rock.
D.
Acidic water dissolves calcite in carbonate rocks.

Answers

Answer:

A. Water reacts with iron minerals in rock to form rust.

Explanation:

Generally, weathering is the process by which rocks are broken down or disintegrated into smaller particles. However, as the name implies, chemical weathering is the weathering facilitated by chemical reactions.

However, there are various types of chemical weathering, of which one is HYDRATION. Hydration is a type of chemical weathering which involves the reaction of water with the chemical constituents of rocks, which eventually disrupt or changes the structure. Therefore, in chemical weathering, water reacts with iron minerals in rock to form rust.

Please help I will give BRAINLIEST face the earth

Answers

Answer:

It is often assumed that the moon is a perfect sphere, which it is not. The side of the moon facing earth is more dense than the side facing away. Therefore, it takes energy for the moon to rotate its earth-facing side away from the earth. Such energy is not currently available, so the same side always faces earth, caught in earth’s gravity.

Explanation:

Hope this helps you a lot my boo!

Answer:

The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth

How can natural selection result
in the adaptation of a population?

Answers

Answer: The traits of those who died before reproducing deemed "undisireable" (like a tale,scales,wings etc.) would have died out as they would not have had the opportunity to pass on these genes. Those of the same species who survived due to a lack of the "undisireable" trait would have the opportunity to reproduce and pass on the complete lack of the trait itself or a smaller version of the trait. This is what enables different species to adapt to live in different enviorments,you can observe this in different species that share a common ancestor.

The distance versus time graph for Object A and Object B are shown.

A graph titles Distance vs Time. A straight slanting line is drawn through point 7 on y axis and this line is labeled Object A. The graph for Object B is a straight slanting line passing through the origin

What is the similarity between Object A and Object B?

Both have the same slope.
Both move with variable speed.
Both move with constant speed.
Both start the journey from the same point.

Answers

Answer:

The correct answer is - Both move with constant speed.

Explanation:

If an object moves in a particular way that it covers the same distance at the same times the speed considered as constant suppose if two objects a and b both travel 10 m and 20 m respectively and the time they take in travel are 2 and 4 seconds respectively than we can say they both have a constant speed.

The relation between the variables x,t, and v is

x=v.t

If V is constant which is the speed we get a straight line x-t in the graph.

By the given information we can say that both objects A and B are traveling at a constant speed.

Michaelis and Menten studied the enzyme sucrase, which uses sucrose as a substrate. Assume that lactose is a competitive inhibitor of sucrase. This could be demonstrated by appropriate kinetic experiments. Think about the kind of data that would be collected in these experiments.On the axes below, show appropriate double-reciprocal plots that would demonstrate that lactose is a competitive inhibitor. Label the axes, and any intercepts with X and Y axes appropriately.The graph can be used to determine whether or Vmax has changed in the presence of lactose. State what it about the graph that allows this, and whether Vmax has changed in the presence of lactose.

Answers

Solution :

In the context, Menten and Michaelis were doing a research. They are studying about the enzyme sucrase that can use sucrose like a substrate.

The intercept on the y-axis gives the value of the Vmax.

As the intercept is same for both the plots, Vmax does not change upon the competitive inhibitor of sucrase.

The graph plotted is provided below.

The answer is MITOCHONDRION

Explanation:

All living organisms need energy at the cellular level to carry out their cellular activities. This energy is obtained by eating food. The energy in food is stored in the bonds of the sugar molecule that is contained in it.

However, via a process called CELLULAR RESPIRATION, the stored energy in food is broken down and used to synthesize a form of energy usable by the cell called ATP. This important process occurs in the organelle called MITOCHONDRION.

Are fibrous proteins heavier than globular proteins in terms of molecular weight? Why?

Answers

Answer:

Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.

Which is an example of an environmental influence that would most likely result in natural selection?
O The soil in a field always has lots of nutrients, so corn plants in a population can grow quickly. O A fish is bom with a genetic mutation that produces a longer tail, allowing the fish to swim faster than others in the population
O A food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot O The temperature in a lake remains constant, so most of the turtle population survives to adulthood​

Answers

Answer:

The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.

Explanation:

Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.

In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.

In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.

The other options are not correct because none of them show environmental pressure that can lead to natural selection.

Answer:

food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
