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 1

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.

Answers

Answer:

ver explicacion

Explanation:

La fotosíntesis es el proceso mediante el cual las plantas verdes fabrican su propio alimento en presencia de luz solar, clorofila, dióxido de carbono y agua.

La intensidad de la luz afecta la tasa de fotosíntesis, cuanto mayor es la intensidad de la luz, mayor es la tasa de fotosíntesis y viceversa. Cuando hay una mayor intensidad de luz, hay más luz disponible para impulsar las reacciones de la fotosíntesis.

Explanation:

Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: increased osmotic pressure in the filtrate that draws plasma through the membrane decreased osmotic pressure in the filtrate that increases the amount of filtration increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration neutral change in osmotic pressure with no effect on filtration

Answers

Answer:

The correct answer is ''increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration.''

Explanation:

Osmotic pressure is understood to be the force that must be applied to a solution when the flow of solvent needs to be stopped by means of a membrane with semi-permeable characteristics.Colloidal osmotic pressure in glomerular capillaries: it is the pressure exerted by proteins in the blood, which tends to recover the filtered water. To generate and maintain glomerular filtration, filtration pressure is required. That is, glomerular filtration is a physical phenomenon regulated by hemodynamic changes that affect the glomerulus and, although it is the initial excretion mechanism, it is not the exclusive regulator. Water, ions and some nutrients are mainly reabsorbed in the proximal tubule by different mechanisms. The water will follow a passive transport process by osmotic drag. The activity of the tubule is highly dependent on maintaining a fluid osmotic pressure similar to that of plasma. Since proteins and other elements that participate in the maintenance of the plasma osmotic pressure do not cross the glomerular barrier, in the tubule, the isoosmotic pressure with the plasma is fundamentally conditioned by the content of water and salt (dissociated as chlorine and Na +) of the ultrafiltered.

Cells and transport proteins are physically prevented from passing through the filtration membrane for this the correct answer is to increase osmotic pressure in the glomerular capillaries that reducing the amount of filtration.

Osmotic strain is known to be the pressure that needs to be carried out to an answer whilst the glide of solvent wishes to be stopped with the aid of a membrane with semi-permeable characteristics.Colloidal osmotic strain in glomerular capillaries: it's far the strain exerted with the aid of using proteins withinside the blood, which has a tendency to get better the filtered water. To generate and keep glomerular filtration, a filtration strain is required.

What is glomerular filtration?

That is, glomerular filtration is a bodily phenomenon regulated with the aid of using hemodynamic modifications that have an effect on the glomerulus and, even though it is the preliminary excretion mechanism, it isn't the different regulator.

Thus it is clear that the above answers are well explained.

Rabbits must be always aware of predators that may catch and eat them. In
natural selection what would we consider these predators?

Answers

anything higher in the food chain

Answer:

There are many rabbit predators that will attack or eat the rabbit, including man. In fact, rabbits have more than most.

Explanation:

Depending in which part of the world you live, will determine the most likely predators you need to be aware of. With domestic/pet rabbits, perhaps the most common predators are pet dogs, pet cats and foxes. However, don't think these are the only ones. Many people are surprised to learn that large birds are a predator to rabbits, especially if the rabbit is a baby, young or a small breed type. Such birds, depending on where you live, include Hawks, Sparrow  Hawks, Owls, Falcons, and kestrels. Other rabbit predators include Weasels, ferrets, badgers, stoats and snakes.

How does the aorta compare in size to the other blood vessels near it?

Answers

Answer: Its wider and thicker than most blood vessels

Answer: The aorta is the largest blood vessel in the body. This artery is responsible for transporting oxygen rich blood from your heart to the rest of your body. The aorta begins at the left ventricle of the heart, extending upward into the chest to form an arch.

Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.

Explanation:

using a named examples explain the differences between a specific body defence mechanism and a non- specific body defence mechanism

Answers

Answer:

Specific body defence mechanism are resistance that are directed against only one specific invader while,

Non specific defence mechanism protects against any of an enormous range of possible dangers.

Explanation:

NON SPECIFIC DEFENCE MECHANISM are the first lines of general defence, they prevent entry and minimise further passage of microbes and other foreign material into the body. There are five main non specific defence mechanisms, these include:

--> defence at body surface

--> phagocytosis

--> natural antimicrobial substances

--> inflammatory response

--> immunological surveillance

Using PHAGOCYTOSIS as a named example of non specific defence mechanism. This involves phagocytes such as the macrophages and neutrophils which are able to trap any invading microbes either by engulfing them or by extending long pseudopodia towards them which grasp them and reel them in. These cells are NON SELECTIVE in their targets.

SPECIFIC BODY DEFENCE MECHANISM directs its actions against a specific invader. In addition immunological memory develops which confers long term immunity to specific infections. The immunity could be cell mediated or antibody mediated immunity.

Using CELL MEDIATED IMMUNITY as an example, Cytotoxic T-cells directly inactivate any cells carrying antigens. This means they are SELECTIVE in their targets. They attach themselves to the target cell and release powerful toxins, which are very effective because the two cells are so close together. This leads to destruction of abnormal body cells such as infected cells and cancer cells.
