The job of the human heart is to circulate blood through all of the body's arteries, capillaries, and veins. The job of the human lungs is to supply the small amount of blood in them with oxygen.
The interaction of these two parts of the human body results in a system that
Question 7 options:
circulates oxygen-filled blood throughout the body.

turns the protein in blood into food energy for the digestive system.
breaks down food energy, and turns it into heat.
Answer:The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

In a reaction that proceeds in the forward direction spontaneously, which has more free energy, the reactant or the product?
Answer:
For chemical reactions where the free energy of the reactants is much greater than the free energy of the products (DGo' < 0), the reaction proceeds spontaneously and the net result is a large ratio of product to reactant (large Keq).

C. Enzymes
D. Proteins
DNA is the genetic information, which must be copied for the next generation of cells.
• The genetic information is stored in DNA and DNA possesses the tendency to replicate and get inherited.
• The genetic information is passed from one generation to the other in the form of DNA.
• The genetic information is passed from parent to the offspring via se-xual or ase-xual mode, and in both the cases it is transferred in the form of DNA.
• The genetic information contained within the DNA of an organism comprises the instructions for all the proteins the organism will ever produce.
Thus, the correct answer is option B, that is, DNA.

Calcium and phosphorus are both essential for the proper growth of
a. bones
b. hair
C. fingernails
d. all of the above
Answer:
The real answer is A.
Explanation:
Calcium and phosphorus are both essential for the proper growth of Bones. So, the correct option is (A).
What are Bones?A bone is defined as the hard organ that forms part of the skeleton in most vertebrate animals and protects various other organs of the body that produce red and white blood cells, store minerals, provide structure and support for and enable mobility.
These come in a wide variety of shapes and sizes and have complex internal and external structures and are strong and rigid as well as being light weight and perform many functions.
Their functions include supporting the body's structure, protecting vital organs and allowing the body to move, and providing an environment for the bone marrow, where the body manufactures blood cells, and they store minerals, especially they act as storage areas for calcium. The skeleton accounts for about 15% of the body weight.
Thus, Calcium and phosphorus are both essential for the proper growth of Bones. So, the correct option is (A).

Which is the best definition of Directional Selection?
A: A process by which two species can no longer reproduce
B: A process by which one of the extreme variations of a trait is favored
C: A process by which individuals with either extreme of a trait are favored
D: A process by which average individuals in a population are favored.
Answer: B A process by which one of the extreme variations of a trait is favored
Explanation:
The best definition of directional selection is as follows:
A process by which one of the extreme variations of a trait is favored.Thus, the correct option for this question is B.
What is Selection?Selection may be defined as the process through which certain traits of organisms become more prevalent in a species than other traits.
Directional direction may be defined as the process through which one extreme is more favored, while the other extreme and an intermediate is having the least favored.
It is of two types negative skewed and positive skewed. Directional selection may also be known as progressive selection or Darwinian selection.
Examples of directional selection include Industrial melanism, DDT-resistant insects, Darwin finches, antibiotic-resistant, etc.
Therefore, the correct option for this question is B.

Interphase lasts for ________ of a cell's life.
A
98%
B
80%
C
50%
D
20%
Interphase lasts for 98% of a cell's life. Thus option A is correct.
What are interphase?Interphase are defined as the G1, S, and G2 phases of the cell cycle, which are the parts of the cycle during which no changes can be seen under a microscope.
It can also defined as when a cell duplicates its DNA to get ready for mitosis during the cell cycle.
G1 phase (cell growth), S phase (DNA synthesis), and G2 phase are the phases of interphase (cell growth). After interphase, the mitotic phase, which includes mitosis and cytokinesis and results in the formation of two daughter cells, starts.
It is important because it enables the cell to develop, replicate its DNA, and finalize preparations for cell division, or mitosis, interphase is crucial for cell division. The cell expands physically and performs its function in the organism during G1. The cell replicates its DNA while it is in the S phase.
Thus, interphase lasts for 98% of a cell's life. Thus option A is correct.

Answer:
They can be reproduced on a human timescale ⇒ Renewable resources
Renewable resources don't take millions of years to form like non-renewable resources. This allows for them to be renewed in a relatively short time.
They take millions of years to form ⇒ Non-renewable resources
Most non-renewable resources are fossil fuels and these take millions of years to form as they are the result of the remains of dead plants and animals being compressed over those millions of years.
They are produced naturally ⇒ Both Renewable and Non-renewable
Both types of resources are produced by natural processes. Fossil fuels are dead animals and plants and renewable resources like wind and solar are natural.
They are extracted by mining ⇒ Non-renewable resources
As mentioned, fossil fuels take millions of years to form and are formed by compression. This compression happens because the dead animals and plants are buried underground. To extract the fuels therefore, they need to be mined.
Their use as an energy source is increasing because they reduce pollution ⇒ Renewable resources
Renewable sources do not cause pollution like non-renewable sources so they are a preferred option when it comes to environmental damage.
