Answer:

b. developing a hypothesis

The first step of the scientific method usually involves making observations. Therefore option D is correct.

Observations are systematic and objective observations of the natural world. Scientists use their senses or specialized tools to collect data and gather information about a particular phenomenon or problem.

These observations serve as the foundation for scientific inquiry and help researchers identify patterns, trends, or potential relationships between variables.

From these initial observations, scientists can then move on to formulating a hypothesis (b), which is a testable explanation or prediction based on existing knowledge and observations.

The scientific method guides researchers in a structured approach to understanding the natural world and conducting experiments to test their ideas.

Therefore option D is correct.

Answer:

The answer is B. Poor access to medical care

Poor access to medical care is most likely to have contributed to the high fertility rate in Africa. Option B is correct.

Fertility rate is the average number of children that a woman will have in her lifetime. In Africa, the fertility rate is high, meaning that women on average have more children than in other parts of the world. There are many factors that contribute to high fertility rates, but one of the most important is poor access to medical care.

When women do not have access to contraception, they are more likely to become pregnant. They are also more likely to die in childbirth if they do not have access to medical care.  In many parts of Africa, girls are married off at a young age. This means that they start having children at a young age, which can lead to higher fertility rates.

In some cultures, it is seen as desirable for women to have many children. This can also contribute to high fertility rates. In some parts of Africa, there are few economic opportunities for women. This can make it difficult for women to support themselves and their children, which can lead to higher fertility rates. Option B is correct.

So to put this in a question, I would rephrase it to:

How does hearing work?

It's a little tough to ELI5 without using using the names of the particular organs but here goes:

Sound is nothing more than a wave of air pressure. In other words, it fundamentally involves changing degrees of energy-based air pushing and tugging. Additionally, it is because to this that sound cannot travel in a vacuum. When these waves reach your ear, they first come into contact with the "tympanic membrane," which vibrates and transmits these vibrations to the malleus, incus, and stapes, three small bones (Latin for hammer, anvil, and stirrup).

The waves will subsequently be transmitted via the bones' vibrations to the "cochlea," a spiral-shaped organ filled with fluid. The air pressure wave has so undergone many transformations at this point. Air pressure was followed by mechanical vibrations and is now "fluid pressure." The spiral-shaped cochlea is lined with neurons all the way around. Depending on the fluid pressure waves' intensity, frequency, etc., the cochlea will have to travel a particular distance. Based on these fluid waves, these neurons will then activate, sending information to your brain.

Your brain then decodes these messages to produce the "sound" that you hear. Although I'm not convinced this is the greatest ELI5, this is the main idea.

In essence, your ear works as follows:

Air pressure waves enter the ear, transform into mechanical vibrations, transform into fluid pressure waves, which signal neurons and cause those neurons to fire electrical impulses that communicate with the brain the sound you are hearing.

Cheers,

ROR

Answer:

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

The amount of water that condensed at the top of the terrarium change as plants sprouted and grew because water, oxygen and nutrients are  very essential elements for growth.

The plant cells grow in size by cell enlargement which in turn requires water. Turgidity of cells helps in extension growth. Thus, plant growth and further development is intimately linked to the water status of the plant. Water also provides the medium for enzymatic activities needed for growth. Oxygen helps in releasing metabolic energy essential for growth activities. Nutrients (macro and micro essential elements) are required by plants for the synthesis of protoplasm and act as source of energy.

Geopolitics can be given as the study of the influence factors such as geography, economics, and demography on politics and especially the foreign policy of a state. Thus, the correct option is D.

Around the turn of the 20th century, the Swedish political scientist Rudolf Kjellén first used the term "geopolitics," which expanded throughout Europe in the years between World Wars I and II (1918–39) before becoming widely used during the latter. Geopolitics is frequently used as a colloquial term for international politics in modern speech.

After World War II, geopolitical theory lost favor due to its links to imperialistic Japanese and Nazi German aggression as well as because the development of nuclear weapons and ballistic missiles diminished the importance of geographical variables in the global strategic balance of power.

The definition of geopolitics stands for the analysis of the factors including geography, economics, and demography on politics and foreign policy. Thus, option D is correct.

Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.

The pancreatic alpha cells that produce glucagon are peptide hormones. It is thought to be the body's primary catabolic hormone since it increases blood levels of glucose and fatty acids. Additionally, it is prescribed as medicine to treat a variety of medical ailments.

When the blood glucose level is too low, the pancreas produces glucagon. Glycogenolysis—the process by which the liver releases glucose into the bloodstream—is triggered by glucagon and occurs in the liver. On the other hand, high blood sugar levels encourage the production of insulin. Insulin-dependent tissues can absorb and utilize glucose with the help of insulin. As a result, the feedback mechanism that maintains steady blood glucose levels includes both glucagon and insulin. Energy expenditure is increased by glucagon, which is higher during stressful situations. The secretin family of hormones includes glucagon.

A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil’s attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.

This article describes how quadrats can be used to help pupils at lower secondary level estimate the relative abundance of plant species. All the information given here refers to frame quadrats.

N an experiment, suppose that the wings of fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on

a. inheritance of natural variations

b. inheritance of acquired characteristics

c. natural selection

d. survival of the fittest

Inheritance of acquired characteristics. Thus, option "B" is correct.

For fifty generations wings of fruit flies were clipped. Hence they acquired this trait in their lifetime and not genetically. If acquired characteristics were capable of passing on to next generation, 50 generations would have been enough to inculcate this clipped wing trait in fruit flies. Despite it, the fifty-first generation did not have clipped wings.

Hence evolution can not occur without genetic variation. A character simply acquired in a lifetime does not create a difference in germ cells and hence is not enough to be passed on to next generation or cause evolution
