Answers

Substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

In which two ways do substances cross the membrane?

The selective passage of substances across the membrane occurs in two different ways:

active transport, when it involves the use of energy.passive transport, when it does not involve the use of ATP.

With this information, we can conclude that substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

Which factor is MOST likely to have contributed to the high fertility rate in Africa?
A-many Economic opportunities
B-poor access to medical care
C-high rate of education
D-Lack of access to food

Answers

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.

Which endocrine hormone promotes the release of glucose from the liver and into the bloodstream?

Answers

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

What is glucagon?

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.

Interdependence is a key concept in ecology. Whilst this can be taught theoretically, some practical fieldwork greatly enhances pupils’ understanding. Almost certainly the fieldwork would entail looking at plant abundance and distribution and, of course, some work with quadrats!

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.

Describe the hearing process​

Answers

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.

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.

What is inheritance of acquired characteristics?

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

Answers

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.

Thus as plant grows it needs more water to provide to it's larger plant body and which causes decrease in the amount of water that condensed at the top of the terrarium.

Which parts of a plant are responsible for reproduction? Describe the role that each of them will play.

Describe what occurs during the process of seed development.

Answers

Answer:

Pollen is carried by insects or blown by the wind from one flower to another. This process is called pollination. Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds. This is fertilisation.So, in providing the seeds that make it possible to grow more plants, flowers benefit the environment by creating more carbon dioxide-absorbing and oxygen-radiating plants. Flowers also play a vital role in cleaning up other parts of our world.Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen. This pollen needs to be moved to a part of the pistil called the stigma.In the process of seed germination, water is absorbed by the embryo, which results in the rehydration and expansion of the cells. Shortly after the beginning of water uptake, or imbibition, the rate of respiration increases, and various metabolic processes, suspended or much reduced during dormancy, resume.

Describe the process of food moving through the digestive tract from mouth to anus. Include in your description the specific functions of at least 3 structures that are part of the process.

Answers

Goes throw mouth in to esophagus into the stomach and getting effect by the stomach acid then goes to the small intestine to the large one then colon and then rectum and Anus

The process of food moving through the digestive tract, from the mouth to the anus, involves several structures and stages.

The description of the process:

1. Mouth: Functions of the mouth include:

Mechanical digestion: The teeth break down food into smaller pieces through chewing and grinding, increasing the surface area for further digestion.Chemical digestion: Salivary glands secrete saliva, which contains enzymes like amylase that begin the breakdown of carbohydrates into simpler sugars.Formation of the bolus: The tongue helps mix food with saliva to form a moistened mass called a bolus, which can be easily swallowed.

2. Esophagus:

After being chewed and mixed with saliva, the bolus moves down the esophagus, a muscular tube connecting the mouth to the stomach. The main function of the esophagus is to transport food from the mouth to the stomach using peristalsis.

3. Stomach: The stomach performs several important functions:

Mechanical digestion: The stomach muscles contract and mix the food with gastric juices, breaking it down further into a semi-liquid mixture called chyme.Chemical digestion: Gastric juices, including hydrochloric acid and enzymes like pepsin, are secreted in the stomach. They help break down proteins into smaller peptides.

4. Small Intestine:

The majority of digestion and nutrient absorption occurs in the small intestine. Enzymatic digestion: The walls of the small intestine produce various enzymes, along with enzymes from the pancreas and bile from the liver.Nutrient absorption: The inner lining of the small intestine contains numerous finger-like projections called villi, which greatly increase the surface area for nutrient absorption. Secretion and reabsorption: The small intestine secretes mucus to protect its lining and reabsorbs some water and electrolytes.

5. Large Intestine (Colon):

Absorption of water and electrolytes: The large intestine absorbs water and electrolytes from the remaining material, making the waste material more solid and forming feces.Bacterial fermentation: Beneficial bacteria in the large intestine ferment certain fibers and produce vitamins, such as vitamin K and some B vitamins.Formation and elimination of feces: The large intestine compacts the waste material into feces and stores it until it is eliminated through the anus during a bowel movement.

Thus, food passes through a number of structures and stages as it moves from the mouth to the anus in the digestive system.
