Charli thinks she does better on tests after she has had coffee in the morning. One morning she drinks a cup of Folger's coffee and then does very well (A-) on her chemistry test. She does it again before her next chemistry test and again does very well (B+). Now she is convinced her hypothesis is right?

Answers

Answer 1

Answer:

Her hypothesis is right.

Explanation:

The Charli's hypothesis is right because caffeine present in coffee helps in boosting of memory if consume it in a normal range. Recent research indicates that caffeine may enhance long-term memory of an individual. When the memory is boost so the individual has the ability to memorize more knowledge that leads to good performance in the examination so the caffeine present in the coffee helps Charli to give good results in the test and we can say that her hypothesis is right.

⦁ Arrange these statements in the right order to describe process of inhalation.

____ Air is drawn into the lungs
____ Air pressure in the chest cavity decreases
____ Lungs expand
____ The diaphragm contracts and flattens
____ The muscles between the ribs contract to move the ribs up and out

Answers

Answer:

air is drawn into the lungs

lungs expand

the muscles between the ribs contract to move the ribs up and down

air pressure in the chest cavity decreases

the diaphragm contracts and flattens

Inhalation has been part of respiration. It includes drawing air into the lungs that expand the lung cavity by pulling the ribs leading to contracting the diaphragm followed by a decrease in lung pressure. Thus the correct order is 1, 3, 5, 4, and 2.

What is inhalation?

Inhalation is the respiratory process to inhale oxygen inside the respiratory system for the cellular and respiratory processes. At first, the air is drawn into the lungs followed by expansion of the lungs.

This causes the ribs muscles to move up and down to accumulate the volume. This movement causes the diaphragm to flatten and contract which allows the oxygen to take place in the lungs that decreasing the air pressure in the cavity.

Therefore, the air is drawn inside the lungs in inhalation.

Answers

Answer:

Resting potential

Explanation:

This is because , the resting potential is negative in side of the cell because it has more negative charge inside than outside due to accumulation of alot of sodium and potassium ions. when an axon is at rest in the cell, the anions produce negative charge, the sodium pumps eject sodium out of the cell and potassium is injected in, and the sodium gates and potassium gates are all closed.

Answers

Answer:

Plzzzz answer fast......

The energy for the photosynthesis reaction is gained in the first stage of the reaction.

There are 2 stages in photosynthesis:

The light-dependent stageThe light-independent stage

During the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.

The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.

The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.

A person has type B blood the possible blood types of his parents can be A x B, A x AB, O x AB, B x AB, AB x AB, B x O, B x B.

What is blood types?

The four main blood types are A, B, AB, and O. Your blood type is determined by the genes your parents gave you.

Red blood cells with blood group A antigens have anti-B plasma antibodies. Plasma from people with blood group B contains anti-A antibodies and B antigens.

Blood group O has both anti-A and anti-B antibodies in the plasma but no antigens. Both A and B antigens are present in blood group AB.

A person with type B blood may have parents who have the blood types A x B, A x AB, O x AB, B x AB, AB x AB, B x O, or B x B.

Thus, these are some of the possible blood types.

3.2.4 Tumour

3.2.5 Bone cancer

Answers

Answer:

3.2.1 Mitosis - Both A and B

3.2.2 Chromosome - Both A and B

3.2.3 Phases in the cell cycle - Both A and B

3.2.4 Tumor - Both A and B

3.2.5 Bone cancer - B only

Explanation:

1. Mitosis is a process of cell replication , in which one cell divides into two identical daughter cells having the same number of chromosomes. In mitosis, the two new cells are genetically identical. Copies of the chromosome (containing the DNA) are made and distributed equally to each cell. Some organisms such as bacteria reproduce entirely by mitosis.

In cloning, an organism that is genetically identical to another organism is made from that original organism. Cloning can occur naturally or may be done by man artificially. In nature, many organisms produce clones through asexual reproduction for example bacteria produces clones by mitotic binary fission.

Therefore, the phrase mitosis, applies to both A and B.

2. Chromosomes are structures found within the nucleus of cells that contain the genetic material of the organism. The chromosomes are composed two identical structures called chromatids thar are joined together to at a constricted point known as centromere.

During cell division, long fibres extend from the centroiles at the ends of the cell to the centromere of the nucleus in order to pull them apart. These long fibres are known as spindle fibres.

Therefore, the phrase, Chromosome, applies to both A and B

3. The phases in the cell cycle are divided into two major stages : interphase and Mitosis. In interphase, the cell grows and makes a copy of its DNA.

In mitotis, the cell DNA divides into two sets, the cytoplasm divides, forming two new cells.

Thus, phases of cell cycle applies to both A and B

4. Tumours are abnormal growths occurring in any part of the body which may be benign or malignant.

Benign tumours are harmless growth which do not have spread out to other tissues to form various cancers.

Malignant tumors spread out from their point of growth to other tissues leading to cancer in these other tissues and organs.

Therefore, tumors applies to both benign and malignant.

5. Bone cancer refers to abnormal growth of bone cells.

Carcinomas are cancers of the skin and tissue lining of organs.

Leukaemia are cancers affecting the bone marrow, whereby the bone marrow makes abnormal white blood cells, red blood cells and platelets.

Thus, bone cancer only applies to B.

Edwin Hubble was an American astronomer who played a crucial role in collecting evidence to support the theory that the universe is constantly expanding outward and is not simply static. He used light from distance stars to calculate their movement.

Meanwhile, around this same period of time, a Russian physicist by the name of Mikhail Lomonosov worked tirelessly in his lab studying different chemical reactions. Lomonosov would later help in developing the Law of Mass Conservation which states that during a chemical reaction the total mass of the substances before the reaction is equal to the total mass after the chemical reaction.

How are the methods used in the pursuit of a scientific explanation different between Edwin Hubble and Mikhail Lomonosov?


A) Edwin Hubble carefully identified and manipulated variables to answer questions; Mikhail Lomonosov made observations about the natural world.

B) Edwin Hubble made observations about what he studied; Mikhail Lomonosov did not

C) Edwin Hubble and Mikhail Lomonosov both used scientific equipment and collected evidence

D) Edwin Hubble made observations about the natural world; Mikhail Lomonosov carefully identified and manipulated variables to answer questions.

Answers

Answer:

C

Explanation:

These type of questions leave a great deal to be desired. There is no mention of which way Hubble used and manipulated data. He studied the variations in light to determine his conclusions.

Nor is there any mention of what Lomonosov did to come to the conclusion that conservation of mass is a constant.

We don't know what was done to get the results. Hubble was studying the universe; the conclusions made by Lomonosov depended on lab equipment that was very delicate (I'm assuming). I doubt he manipulated variables. He measured what he got.

I think the answer is C, but the question has so many assumptions that it is hard to know what answer to pick.
