Hebrews 11:7

Answers

Answer:

Faith, according to the Bible, is not blind. More than half of the verses in the book of Hebrews are dedicated to explaining reasons and evidence to accept the new covenant in Jesus Christ. Nor is faith gullible, or senseless. Instead, godly faith is exemplified by trust. That trust is based on what we know of God, relying on Him for the things we do not know. In particular, godly faith looks forward, from an eternal perspective, and produces obedience, even in the face of hardship. God takes what we cannot see, or cannot understand, and uses it to make good on His word. Since faith relies on what we've seen of God, and trusts Him for the future, it becomes the "assurance of things hoped for, the conviction of things not seen" (Hebrews 11:1–3).

Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?

Answers

Answer:

There needs to be variations in population in order for natural selection to occur because the entire point of evolution by natural selection is only the best variations will survive. So if there were no variations then there would be no natural selection because the animal's survival rate would be the same no matter how many times they reproduce because there are no different variations being introduced into the species. However, if there are variations then the animal's survival rate could be impacted because of the variations, for example, white mice would be easier to find for predators on a dark surface, while a darker mice would be harder to find for predators on a dark surface, thus, allowing the darker mice to prevail as they have a higher survival rate and the species will slowly evolve into the darker mice. But, if there were no evolution, in this case, then no matter what happens, the white mice would not be able to evolve into a darker mice because there are no such thing as variation. That is why it is necessary for there to be variation in order for evolution by natural selection to occur.

Briefly explain how DNA profiling is used to identify individuals.

Answers

A sample of DNA is taken from blood of saliva. PCR makes lots of copies, or amplifies the DNA. We then add restriction enzymes to cut the DNA at palindrome sequences. We then run the DNA through gel Elecrophoresis. Each person has unique short tandem repeats that cause a unique number of cuts by the restriction enzyme. These cuts are separated by size on gel electrophoresis, so no two people have the exact same pattern. We can compare individuals banding patterns to what is found at a crime scene, taken in previous samples, in a baby, and the sample that matches all the banding patterns will be the individual.

Simone is creating a model to track the movement of carbon atoms in an ecosystem. Which statement best explains the role of plants in Simone's model?

Answers

Although I cannot see the model for Simone's experiment, I can offer the insight that the most likely role of plants in the model is that they consume the carbon atoms and produce oxygen.

How do plants affect the carbon in the atmosphere?Plants are known to have a great effect on the carbon levels of the atmosphere. The correlation is that the more plants are present, the less carbon is free in the air. The reason for this is that plants use carbon dioxide as a substrate to manage the process of photosynthesis.As a by-product, after consuming carbon dioxide and completing photosynthesis, plants release oxygen into the atmosphere.

Therefore, we can confirm that the most likely role of plants in the model created by Simone, is that they will consume carbon atoms in the form of carbon dioxide in order to sustain photosynthesis, which releases oxygen.

Answer: law of motion

Explanation:

Newton’s first two laws of motion explain how the motion of a single object changes. If the forces acting on the object are bal- anced, the object will remain at rest or stay in motion with con- stant velocity. If the forces are unbalanced, the object will accelerate in the direction of the net force. Newton’s second law tells how to calculate the acceleration, or change in motion, of an object if the net force acting on it is known.

Newton’s third law describes something else that happens when one object exerts a force on another object. Suppose you push on a wall. It may surprise you to learn that if you push on a wall, the wall also pushes on you. According to Newton’s third law of motion,

Answers

Explanation:

glucose

The mammalian brain depends on glucose as its main source of energy. In the adult brain, neurons have the highest energy demand [1], requiring continuous delivery of glucose from blood.

The major source of energy for the brain is glucose. Metabolism of glucose provides energy to the brain.

What is the brain?

The brain is a body part that operates the various functions of the body. It is present in the head of the body. It is divided into two parts, the left brain, and the right brain.

Energy is something that is produced by the metabolism of food. Energy7 is required to carry out all the processes of the body. To walk, run, work, eat, everything requires energy.

The main source of the energy in animals and plants is glucose. The food we eat converts into energy by the process of respiration. The energy is transported into all parts of the body by blood circulation.

Thus, glucose is the major source of energy for the brain.
