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.
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.

A ____________ is a series of nucleotides that encodes a protein product. This coding DNA may have different forms, or varieties, called ____________ . An individual with two different versions of a gene is genetically ____________ . In traits with a simple pattern of inheritance, only the trait conferred by the ____________ form of the gene will be visible. The other form of the gene is ____________ : it confers a trait that is only visible when the individual is genetically ____________ , or has two identical copies of the gene.
Answer:
Gene; alleles; heterozygous; dominant; recessive; homo-zygous.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Filling up the blanks in the question, we have;
A gene is a series of nucleotides that encodes a protein product. This coding DNA may have different forms, or varieties, called alleles. An individual with two different versions of a gene is genetically heterozygous. In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene will be visible. The other form of the gene is recessive: it confers a trait that is only visible when the individual is genetically homo-zygous, or has two identical copies of the gene.
6. Which marrow was denser (had more mass in the given volume)? What impact would that have on the overall density of the bone?
Answer:
The beef bone marrow was denser than the chicken bone because it had more mass in the given volume. Since the chicken must fly, it cannot have its bones weighing it down on the land. However, cows must find grass on land and travel long distances. This would increase the overall density of the bone.

⦁ 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
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.

describe how energy for the photosynthesis reaction is gained by plants (2)
please help
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 stageDuring 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.

For each of the following processes, identify the part of the chloroplast in which it takes place. Light-dependent reactions Light-independent reactions Sun’s energy absorbed Sugars produced
Answer:
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

1. What causes the inside of the cell to be more negative compared to the outside of the cell? Resting Potential, Action Potential
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.
3.2 State whether each of the phrases applies to A only, B only,
both A and B or none. Write down A only, B only, both A and B
or 'none' next to the question number.
For example, 3.2.6 None
3.2.1 Mitosis
A cloning
B chromosomes
3.2.2 Chromosome
A chromatid
B spindle fibre
3.2.3 Phases in the cell cycle
A interphase
B mitosis
3.2.4 Tumour
A benign
B malignant
3.2.5 Bone cancer
A carcinoma
B leukaemia
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.

Explanation:
1. All animals except sponges have tissues, groups of cells that work together to perform a specific function.
Sponges are sea animals which are found attached to surfaces. They are multicellular and heterotrophic like other animals, but they lack true tissues and organs.
2. All animals eat other organisms in order to gain building materials for the body. This makes them heterotrophic, since they obtain necessary energy and chemical building blocks from the environment.
Heterotrophs are organisms that cannot manufacture their own food, but obtain it from their environment instead.
3. One key adaptation of animals was the evolution of a body cavity, a fluid-filled gap between the outer wall of the body and the outer wall of the digestive system.
A body cavity is a space found inside the body that is filled with fluid and which holds and protects internal organs. There are several cavities found in the human body and they are separated by membranes as well as many other structures.
4. All animals are eukaryotes, organisms with cells that are relatively large, complex, and contain membrane-enclosed organelles such as the nucleus.
5. Cnidarians are the only animal phylum to display radial symmetry, meaning that their bodies can be divided any way through the center point to yield two even halves.All other adult animals display bilateral symmetry, meaning that their bodies can only be sliced lengthwise through the midline to produce two even halves.
