why is the dominant allele seen in a heterozygous individual
Answer: Since it's the DOMINANT allele that means that it will take over reccesive allele that's why it's shown.
Explanation: A heterozygous individual is an individual where the have both the dominant and reccesive allele for a trait. The dominant allele will always be stronger than the reccesive allele. This results in the dominant allele being shown.

Describe the rock layers shown in Diagram A and any forces acting on the rock.
The rock in diagram A has three horizons and no force acts on it.
What is a rock?A rock is a geological term that refers to solid materials, made up of crystals or grains of one or more minerals. Rock is the main material in the Earth's crust.
Four diagrams of the Earth's crust are shown in the image. All four have three horizons and different forces influence them except A. These forces are caused by the movements of the Earth's lithosphere and are represented by arrows in the direction of movement.
In the case of diagram A, having no arrow means that no force acts on it. Additionally, you can see the three horizons or layers that make up this sample of land.

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

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.
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.
elect the correct statement regarding the lungs. Select one: a. The left lung is larger than the right lung. b. Only the right lung has a hilum. c. The left lung contains three lobes while the right lung contains two lobes. d. The left lung has more bronchopulmonary segments than the right lung. e. The left lung contains two lobes while the right lung contains three lobes.
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.

The policy which would would increase the risk of a liquidity crisis is Banks
being required to store a smaller percentage of depositor funds in their
vaults.
Liquidity occurs when there is an increase in demand and decrease in
supply. Banks usually have a large percentage of depositor funds stored in
their vault to prevent these occurrence.
