Which would provide the body with the most energy? a. Carrying oxygen from the lungs to the cells b. Breaking the bonds in a disaccharide c. Breaking a single carbon bond d. Creating bonds to make a simple sugar

b. Breaking the bonds in a disaccharide. Disaccharides are sugars, sugars are the body's primary fuel. Starch for example is the complex sugar found in plants, broken down in the body to form glucose which is a great source of energy for the body. When the stomach digests food, the carbohydrate in the food breaks down into another type of sugar.

Why is a convex mirror used to look under a vehicle during a security check? A- it forms images that are real, inverted,smaller,and closer B-it provides a narrow field of view and the images formed are virtual, upright,front back reversed, of same size, and at same distance C-it provides a wider field of view and the images formed are virtual but smaller and upright D-it provides a diminished view and the images formed are virtual, upright and bigger

Answer: Option 'C' is correct.

Explanation:

convex mirror is used to look under a vehicle during a security check because it provides a wider field of view and the images formed are virtual but smaller and upright.

As the image of convex mirror provides rear view in a small frame.

i.e. the images formed by convex mirror are virtual and as it covers wider range, the image is smaller than real but upright.

Hence, option 'C' is correct.

Why is meiosis important for organisms? It allows for genetic variation among organisms. It determines which genes are dominant and which are recessive. It produces genetically identical cells. It provides a means of asexual reproduction.

Genetic variation. Meiosis is the combination of 2 haploid cells so it's not asexual reproduction. Meiosis doesn't produce identical cells-mitosis does. And it doesn't determine which genes are dominant or recessive - there are equal chance of inheriting dominant/recessive genes, but the dominant one is expressed as phenotype

Which is the end result of cytokinesis? one cell that has two identical copies of DNA one cell that has two different copies of DNA two cells that have two identical copies of DNA two cells that have two different copies of DNA

The end result of cytokinesis is TWO CELLS THAT HAVE TWO IDENTICAL COPIES OF DNA.

Cytokinesis refers to the last stage of either the mitosis or the meiosis. It involves the cytoplasmic division, which brings about the separation of the two daughter cells that are formed. It is a physical process, which finally divide the cells into two and at the same time ensuring that each cell has its own nucleus. At the end of cytokiness, two cells are formed that possess identical copies of DNA.

An acorn with a mass of .0300 kilograms is hanging from a branch in a tree. It is 2.50 meters from the ground. What is the potential energy of the acorn?

The answer is 0.74 J.

The potential energy of the object is its stored energy. Gravitational potential energy is the stored energy of the object as the result of its height can be expressed as:
E = m · g · h
where
E - the potential energy of the object,
m - the mass of the object,
g - gravitational acceleration (g = 9.81 m/s²),
h - the height of the object.

It is given:
g = 9.81 m/s²
m = 0.03 kg
h = 2.5 m

Therefore:
E = m · g · h
⇒ E = 0.03 kg · 9.81 m/s² · 2.5 m
⇒ E = 0.03 · 9.81 · 2.5 kg ·m/s² · m
⇒ E = 0.74 kg ·m²/s²
⇒ E = 0.74 J

Therefore, the potential energy of the acorn is 0.74 J.

Which carbohydrate can be used by the body as an immediate source of energy?

Glucose

Carbohydrates actually get stored in the form of long polymers of glucose molecules or as glycogen starch. They provide energy to the animals for performing their daily duties. Carbohydrates are generally considered the fuel for all organisms, and without this most animals would become sloth and would be unable to perform the regular jobs. Carbohydrates are actually very easy to metabolise and hence generate quick energy.

What is the end result of meiosis? four identical daughter cells four different daughter cells two identical daughter cells two different daughter cells

Answer;

Four identical daughter cells

Explanation;

-Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

-In Meiosis one diploid cell produces 4 haploid daughter cells i.e. having half the chromosome number than the somatic cell of same organism. Therefore, as a human cell has 46 chromosomes, each haploid cell gets 23 chromosomes.

QUESTION POSTED AT 18/01/2020 - 12:46 PM

Which statement best compares potential and kinetic energy? Objects always have more potential energy than kinetic energy. Only kinetic energy increases when the velocity of an object increases. Only potential energy decreases when an object’s height increases. Objects always have more kinetic energy than potential energy.

The correct answer for above statement is:

Only kinetic energy increases when the velocity of an object increases.

Explanation:

It is considered as the work required to expedite the object of provided mass from the rest position to designated velocity. The kinetic energy of an object raises because of the network was done over it. Accordingly, when the object gets acceleration from the state of rest to the change it gains velocity. Thus, determining when the kinetic energy of an object improves velocity increases.

Ron is observing an onion cell on a slide under a microscope. He sees chromatids being pulled to opposite ends of the cell. Which phase is he seeing?

The answer is anaphase.


Ron is obviously observing cell division - mitosis. Mitosis consists of four phases - prophase, metaphase, anaphase, telophase and cytokinesis.

1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up

2. Metaphase: Chromosomes line up at the center of the cell. The sister chromatids are joined together.

3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.

4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.

 

Therefore, sister chromatids being are pulled to the opposite ends of the cell in anaphase.

Is diffusion the only way materials can enter the cell? Explain.

Of course not! There's lots of ways materials can enter. It also depends on the cell; whether it has cell wall and cell membrane or only cell membrane.

Besides diffusion, there's also osmosis and active transport.

If the cell has only cell membrane, it means it's partially permeable, which means osmosis can happen.

As blood flows through the capillaries in the lungs, it drops off and picks up .

Answer: The correct answer is-

As blood flows through the capillaries in the lungs, it drops off and picks up carbon dioxide and oxygen respectively.

Deoxygenated blood ( carrying carbon dioxide) reach lungs from right ventricle of heart via pulmonary artery, which decreases diameter and forms capillaries on the alveoli ( tiny air sacs in the lungs for the gaseous exchange).

Thus, oxygen is taken up by the blood ( so as to transport it to the rest  of the body) whereas carbon dioxide ( which is a waste product of metabolism in the body) is dropped at lungs, which is then released out of body through exhalation.
