The enzyme lactase breaks the sugar lactose into which compound(s)

Answers

Answer 1

Final answer:

The enzyme lactase breaks the sugar lactose into two simple sugars: glucose and galactose. These can be absorbed into the bloodstream and used for energy.

Explanation:

The enzyme called lactase plays a vital role in the human digestive system. Specifically, this enzyme breaks down the sugar lactose, which is found in dairy products, into two simpler sugars: glucose and galactose. These simple sugars can then be easily absorbed into the bloodstream and used by the body for energy. For example, if you consume a glass of milk, the lactase enzyme in your small intestine will break the lactose present in the milk down into glucose and galactose.

Answer 2

Final answer:

The enzyme lactase breaks down the sugar lactose into glucose and galactose. These are simpler monosaccharide units, which the body can easily absorb and use for energy.

Explanation:

The enzyme lactase breaks down the sugar lactose, a disaccharide, into simpler compounds. These compounds are two monosaccharides, namely glucose and galactose.

This process is vital for the digestion of lactose found in dairy products. If an individual does not produce sufficient lactase, the lactose cannot be broken down properly. This can lead to lactose intolerance, where the undigested lactose causes gastrointestinal symptoms.

Yesterday nadia consumed 250 grams of carbohydrate, 75 grams of protein, and 60 grams of fat. 57) what percentage of calories of her day's intake came from fat?

Answers

number of calories gained when eating different types of food differs. Some food types are more fattening relative to other types.
the number of calories consumed when eating carbohydrates -
- 4 calories/ gram * 250 g = 1000 calories
calories gained eating proteins -
- 4 calories/gram * 75 g = 300 calories
calories gained eating fats
- 9 calories/ gram * 60 g = 540 calories
total amount of calories consumed = 1000 + 300 + 540 = 1840 calories

percentage of calories coming from fats = 540/1840 *100% = 29.3 %

"what advantage do organisms that reproduce sexually have over organisms that reproduce asexually?"

Answers

Organisms that reproduce sexually have greater genetic and thus characteristic variations, and so, are able to withstand more selection pressures if they so happen to change or become greater. This increases the chances of survival for that species itself.

Organisms that reproduce asexually are genetically identical to each other. They are unlikely to withstand any changes in selection pressures.

Identify the two main regions of a typical mollusk's body

Answers

Head foot and visceral mass

Most of the mollusks species are gastropods. The body of the mollusk is made of shell and fleshy part. The fleshy part is divide into foot and visceral mass. Foot is a distinct feature of mollusk. They use it mainly for locomotion. The visceral mass involves the organs for circulation, digestion and other important processes in living organism. The visceral mass has two external flaps of tissue called as the mantle. It secretes calcerous shell and encloses a mantle cavity.

The main regions of a typical mollusk's body is head foot and visceral mass. The Mollusks are soft bodied invertebrates. They have 4 body parts that are head and foot, shell, visceral mass and mantle. The main two parts are the head and foot and visceral mass. The Visceral mass is where digestion, respiratory, reproductive and excretory are held. On the other hand the foot is used to give a sense of balance and the head is used to carry one or two tentacles.

Continuous cell lines differ from primary cell lines in that question 12 options:

c.continuous cell lines always have to be reisolated from animal tissues.
d.continuous cell lines are derived from primary cell lines.
e.continuous cell lines are from human embryos.

Answers

Continuous cell lines differ from primary cell lines in that continuous cell lines are derived from primary cell lines.

Continuous cell lines can be propagated indefinitely, while primary cell lines have a limited lifespan.

Option (b) is correct.

Continuous cell lines differ from primary cell lines in that they can be maintained and propagated through an indefinite number of generations, whereas primary cell lines have a limited lifespan and eventually undergo senescence or cell death.

Continuous cell lines are derived from primary cell lines through a process called immortalization, where they acquire the ability to divide indefinitely. These cell lines are often used in research laboratories and biotechnology applications because of their ability to provide a continuous and consistent source of cells.

Unlike primary cell lines, continuous cell lines do not need to be reisolated from animal tissues repeatedly. They can be cultured in the laboratory under specific conditions, and they are widely used for studying cell biology, drug testing, vaccine development, and viral propagation, among other applications.

Circulatory systems compensate for _____. circulatory systems compensate for _____. the problem of communication systems involving only the nervous system the need to cushion animals from trauma temperature differences between the lungs and the active tissue the slow rate at which diffusion occurs over large distances

Answers

Circulatory systems compensate for the slow rate at which diffusion occurs over large distances.

Diffusion is the process of molecules moving from a place of high concentration to a place of low concentration, which happens thanks to the chemical potential gradient, such as the concentration gradient (the difference in the concentrations). This process is used by our cells, for example, in the transport of oxygen, since it can diffuse through the cell membrane and into the cell, when the concentration of oxygen is higher in the intercellular space.
Diffusion is generally a slow process when it comes to large distances, so for example, oxygen would take a lot of time to get from one place in the body to another, since it would have to diffuse through millions of cells.
This is where the circulatory system comes into play. Thanks to the circulatory system, the oxygen can simply enter the blood flow, and be transported by the hemoglobin in the red blood cells from our lungs to all the cells in our body much faster. Same goes for different molecules that the circulatory system transports, like nutrients, amino acids, carbon dioxide, hormones. These are all transported throughout our body at a rate much faster than the rate of diffusion, and diffusion is used in the capillaries, at the target cells after the molecules have already been transported by the blood.

Final answer:

The circulatory system compensates for the slow rate at which diffusion occurs over large distances, facilitating efficient transport of materials within the body. Additionally, it also compensates for the limitations of having only the nervous system for communication by disseminating signals broadly to the body via hormones and other messengers.

Explanation:

The circulatory system compensates for the slow rate at which diffusion occurs over large distances, amongst other functions. Within the body, materials like oxygen, nutrients, and waste products need to be transported from one region to another. Relying on simple diffusion would be quite inefficient due to the slow rate at which it processes. Therefore, the circulatory system acts as a network of highways, speeding up the transport process significantly.

Furthermore, it's critical to understand that the circulatory system also compensates for the problem of communication systems involving only the nervous system. While the nervous system is crucial for fast and targeted responses, the circulatory system disseminates hormones and other signals broadly to the entire body. It’s a slower communication method, but it affects all parts of the body simultaneously, which can be beneficial for many types of responses.

Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and __________.

Answers

Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. Like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and cell lysis. Antimicrobilas that act by inhibiting cell wall synthesis include beta-lactams, vancomycin and cycloserine and isoniazid and ethambutol among others. They prevent bacteria from increasing amount of peptidoglycan, they have no effect on existing peptodoglycan layer and therefore are effective only for growing cells.

Final answer:

Bacitracin is an antibiotic that inhibits bacterial cell wall synthesis, causing the cell wall to weaken and eventually leading to cell lysis or the bursting of the cell due to osmotic pressure. This means that the bacitracin is particularly effective against certain types of bacteria, while not harming human cells. It is commonly used in topical ointments due to potential kidney damage from prolonged use.

Explanation:

Bacitracin is a peptide antibiotic that inhibits bacterial cell wall synthesis by blocking the movement of peptidoglycan precursors, N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM), across the cell membrane. The cell wall becomes weak due to insufficient peptidoglycan, a major component of the cell wall in bacteria. This results in cell lysis, where the cell bursts due to osmotic pressure because the cell wall can't hold the cell contents.

Bacitracin, like other cell wall synthesis inhibitors such as B-lactams and glycopeptides, exhibits selective toxicity as it targets a feature not present in human cells - peptidoglycan in the cell wall. Antibacterials like bacitracin are effective and popular because they do not harm human cells at the same time as they kill bacterial cells, which makes them particularly potent against Gram-positive bacteria like Staphylococcus and Streptococcus commonly found on the skin. However, it's important to note that prolonged use of bacitracin can lead to kidney damage, so it is often used in combination with other antibiotics like neomycin and polymyxin in topical ointments such as Neosporin.

The part of the nervous system that arouses a person is the sympathetic nervous system and the part of the nervous system that calms a person is the parasympathetic nervous system.

The Autonomic Nervous System (ANS) is part of the peripheral nervous system (PNS) and is further divided into these two subsystems. The sympathetic nervous system prepares the body for 'fight or flight' responses by increasing heart rate, dilating pupils, and redirecting blood to muscles. On the other hand, the parasympathetic nervous system promotes 'rest and digest' activities by slowing the heart rate, reducing blood pressure, and promoting digestion to help the body recuperate.

The flow of surface run-off can be controlled by building retaining walls called _____.

Answers

Final answer:

The flow of surface run-off can be controlled by building retaining walls called levees, which are key components of flood control systems. In addition to levees, reservoirs collect and store water for various uses, and conservation efforts are important for sustainable water management. Aqueducts and desalination are other methods used to meet freshwater demands.

Explanation:

The flow of surface run-off can be controlled by building retaining walls called levees. The purpose of a levee is to prevent the overflow of rivers, lakes, or oceans from flooding adjacent land. Levees are often part of a larger flood control system, which may include dams and reservoirs. By building a levee, water is contained within the riverbanks, and the risk of flooding to surrounding areas is reduced.

Another method of controlling water flow is through the use of sandbags, which can be placed around potential breaches or leaks in levees or embankments as a temporary measure. According to Environmental Biology 207, sandbags can balance a massive body of water by creating a barrier that stops further flow. Reservoirs also play an essential role by collecting water and storing it for use during drier periods, providing benefits such as water supply, hydroelectric power, flood control, and recreation.

Conservation and Sustainable Management of Water

Conservation is crucial for sustainable water management, involving measures like high-efficiency appliances and behavioral changes to reduce water consumption. In areas where water is scarce, desalination can provide fresh water by removing salt from seawater, although this process is expensive and energy-intensive. Aqueducts transfer water from regions where it is abundant to those where it is needed, but they can lead to controversial political issues and environmental impacts on the source regions.

How does using killed or weakened bacteria in an immunization help the body prevent infections?

A.) Antibodies are formed that fight those types of bacteria.
B.) The body develops a fever that kills beneficial bacteria.
C.) Bacterial reproductive cycles are disrupted.
D.) Bacteria-fighting viruses are activated.,

Answers

The answer is A.) Antibodies are formed that fight those types of bacteria.

To explain, your immune system protects you from invasive bacteria by attacking and destroying them. The problem is that your system needs to recognize invading organisms like bacteria. Remember that bacteria cells have many of the same types of structures as your own cells, and you do not want your immune system to attack your own body. Special cells called T-cells and B-cells participate in this process. To make a long story short, antibodies are special molecules that your immune system "labels" invading bacteria with, so that it knows what to attack. These antibodies only fit on molecular structures of the targeted bacteria.

When a dead or weakened bacteria, or even pieces of a bad bacteria are introduced to the body, the B-cells and T-cells create antibodies that label that specific type of bacteria, or even its parts. They also remember how to make them in the future, so that later, when and if infected with a live version of that bacteria, the immune system already makes the antibodies to fight that infection. The process can work for viruses too.
