Answer 2

Weathering is the process by which rocks disintegrate into smaller fragments. Rock expands (with heat) and contracts (with cold) in response to temperature changes.

What is Weathering?

Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.

Rock responds to temperature fluctuations by expanding with heat and contracting with cold. This is frequently observed with a weathering process known as Frost wedging, in which water freezes and thaws inside rock fissures. Salt wedging is a different type of weathering in which the salt that is left over after water evaporates can exert pressure on rock fissures.

Thus, Weathering is defined as the process by which rocks disintegrate into smaller fragments.

Which structure allows
gases and nutrients in
and out of the cell?
A. mitochondria
B. cytoplasm
C. nucleus
D. cell membrane

Answers

cell membrane as it is a semipermeable surface

The cell membrane allows gases and nutrients in and out of the cell.

The correct answer is option D, the cell membrane. The cell membrane, also known as the plasma membrane, is a vital component of all cells. It serves as a selectively permeable barrier that separates the internal environment of the cell from its external surroundings. One of its crucial functions is to regulate the movement of substances in and out of the cell, including gases and nutrients.

The cell membrane is made up of a phospholipid bilayer embedded with various proteins. These proteins play a role in facilitating the transport of molecules across the membrane. There are two main types of transport across the cell membrane:

Passive Transport: This includes processes like diffusion and facilitated diffusion, where substances move from an area of higher concentration to an area of lower concentration. Small gases like oxygen and carbon dioxide can passively diffuse through the lipid bilayer of the membrane.

Active Transport: This involves the use of energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Nutrients and other molecules can be actively transported using protein pumps.

In both cases, the cell membrane is responsible for controlling what enters and exits the cell, maintaining an appropriate internal environment for cellular functions. This selective permeability ensures that essential gases like oxygen and nutrients can enter the cell while waste products can exit. Thus, the cell membrane is a crucial structure that enables the exchange of gases and nutrients required for cellular metabolism and survival.

The left lung contains two lobes while the right lung contains three lobes.

Answers

Answer:

The right lung is smaller than the right to make room for the heart.

Explanation:

so the answer is A :)

The left lung contains two lobes while the right lung contains three lobes. Therefore option E is correct.

The statement that the left lung contains two lobes while the right lung contains three lobes is correct.

The right lung is divided into three lobes: the upper lobe, middle lobe, and lower lobe. On the other hand, the left lung is divided into two lobes: the upper lobe and lower lobe.

This anatomical difference is due to the position of the heart, which is located more towards the left side of the chest. The presence of an additional lobe in the right lung allows for a better fit around the heart.

Understanding the lobes of the lungs is important in assessing and diagnosing respiratory conditions and in surgical procedures that involve lung resection or transplantation.

Therefore option E The left lung contains two lobes while the right lung contains three lobes is correct.

Why can’t a virus reproduce on its own?

Answers

Answer:

Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.

At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids.

They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria).

A virus that infects bacteria is known as a bacteriophage, often shortened to phage.

The study of viruses is known as virology, and those who study viruses are known as virologists.It has been argued extensively whether viruses are living organisms.

Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life.

They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.

A primary reason is that viruses do not possess a cell membrane or metabolise on their own - characteristics of all living organisms.

Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores.

What is a similarity between phases of moon wi2 and wk 4

Answers

The similarity is that in both phases, the moon is only ¼ lit.
The moon has four phases, which happen in a fixed sequence. Each phase lasts one week and takes place as follows:

1st week - New Moon: At this moment, the part of the moon that is illuminated by the sun is not facing the earth. This prevents the moon from being seen.

2nd week - Crescent Moon: Only ¼ of the moon is being lit by the sun and facing the earth. Therefore, we can only visualize a small part of the moon.

3rd week - Full Moon: The face of the moon that is facing the earth is completely illuminated by the sun, which allows this entire face to be visualized.

4th week - Waning moon: Once again, only ¼ of the moon is lit by the sun and facing towards the earth.

The moon does not have its own light, but reflects the light received by the sun, for this reason, we cannot fully visualize the moon.

Which of the following statements regarding digestion and absorption of carbohydrates is TRUE? Lactose intolerance results from an insufficiency of the enzyme amylase. Digestible polysaccharides are broken down into the monosaccharides glucose, galactose, and fructose, which can be absorbed. Sucrose is the main form of carbohydrate that can be absorbed by active transport across the intestinal epithelium. Carbohydrate digestion begins in the stomach. Cellulose from plants is a polymer of glucose that can be easily digested and absorbed by the human GI tract.

Answers

Answer:

CARBOHYDRATE DIGESTION AND ABSORPTION

For dietary carbohydrates to be utilized by the body, they must be converted during digestion to monosaccharides. In addition to starch, the other major dietary carbohydrates are the disaccharides lactose and sucrose, and the monosaccharide fructose. The monosaccharides produced by complete digestion of these dietary carbohydrates are glucose, galactose, and fructose.

The digestive process begins with salivary amylase, which randomly cleaves the α-1,4 linkages of starch. Although amylase digestion begins in the saliva, pancreatic α-amylase is more important to the complete digestion of starch (Fig. 19-1). Starch is degraded first to dextrins and then to a mixture of glucose, maltose, and isomaltose (containing the α-1,6 linkages that are not digested by amylase).

The major disaccharidases, located in the brush border of the intestinal lumen, are

Maltase—hydrolyzes maltose

Sucrase-isomaltase—hydrolyzes sucrose and isomaltose

Lactase—hydrolyzes lactose

Whenever lactose goes undigested, it is not absorbed and passes into the large intestine. Here lactose is acted on by the intestinal flora that ferment it, producing large quantities of CO2, hydrogen gas, methane, and organic acids; the last irritate the intestines, increasing intestinal motility. All these products have only one way out. Thus, the symptoms that characterize lactose intolerance are bloating and flatulence and, in extreme cases, a frothy diarrhea. Lactose intolerance is least common in Northern Europeans and their descendants and most common in descendants of Asian, African, and South American origin.

HISTOLOGY

Brush Border Dynamics

The unstirred brush border of the intestinal lumen consists of finger-like processes, known as microvilli, of the surface absorptive cells. Many enzymes associated with the process of digestion and absorption are located on the surface of these microvilli. This allows the products of digestion such as free fatty acids, amino acids, and monoglycerides to be absorbed by the cells rather than be swept into the lumen itself.
