Lactase is an enzyme that is produced in the lining of the intestines. This enzyme helps the body speed up the
breakdown of carbohydrates that are found in dairy products, such as milk, yogurt, and cheese.
Which general function does lactase perform?
Answer:
Regulation of cell processes
Explanation:
Lactase is an enzyme that helps in the breaking down of disaccharide sugar, lactose, found in many foods. It does it by converting the lactose into its component reducing sugars - glucose and galactose. This enzyme is produced by some special cells lining the intestinal walls of humans and forms a kind of chemical barrier known as brush border where foods must pass through before being absorbed. By so doing, foods are screened for the presence of lactose and any lactose is broken down before the foods are given a pass.

What is a group of microscopic unicellular organisms
ii) Explain briefly how these features contribute to the efficiency of photosynthesis?
Answer:
here's your answer
Explanation:
the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.
Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves

Which way do the chlorophyll bands move on the chromatography paper?
Answer:
They move up the chromatography paper.
Because the movement of the chlorophyll bands on the chromatography paper is dependent on the stationary phase and the mobile phase, the pigment separates different colors when moving the top of the paper.
What is the significance of chromatography?Chromatography is a technique that is used to separate and analyze a mixture of chemical substances and is a powerful tool in various fields such as chemistry and biochemistry. The significance of chromatography is that it allows scientists to identify and quantify individual components in a mixture and these techniques are helpful for the synthesis of drugs and other chemical products.

First, you introduce to the parents the importance of karyotype test, by describing its ability to detect two broad categories of abnormalities in chromosomes, (1)______________________ and (2)_______________________. You provide a few examples of genetic disorders that can be caused by chromosomal abnormalities, such as (3)_________________________ and (4)_____________________. Some parents would like to know what is the main cause of these genetic disorders. Without going into too much detail, you explain to them that chromosomal abnormalities are usually caused by (5) ____________________ in meiosis I and meiosis II, when the homologous chromosomes or sister chromatids fail to separate during meiotic cell division.
Answer:
Abnormalities in Chromosomes
1. Numerical
2. Structural
3. Down Syndrome
4. Turner Syndrome
5. Disorder or Error
Explanation:
Numerical chromosome abnormalities occur due to extra or missing chromosomes. Structural chromosome abnormalities occur due to the irregular formation or rearrangement of the chromosomal DNA, normally called translocation. Down syndrome occurs with extra chromosomes, more than 46. Turnover syndrome results from partial or missing X chromosomes, less than 46.

The rubber diaphragm is the model to demonstart the various parts of the respiratory system and how they move during breathing process. In case of it moves down, the rubber diaphragm is stretched, the volume inside the bell jar increases which causes presursue decrease.
Balloon inhale or sucks in the air from outside and gets inflate. this increases the volume in the jar. The pressure is increased
Elizabeth was a "granola mom"it was only natural and organic foods and therapies for her
family. She belonged to a food co-op and ordered special foods and home remedies through
the group
Elizabeth was well read and conscientious, and she had a remedy for everything
Little white pills that dissolved under the tongue treated everything from teething to bruising.
When her 8-year-old daughter Samantha had a sore throat, Elizabeth had her gargle with
colloidal silver remedy used before all the new and "dangerous" antibiotics. Samantha did
get over her sore throat, but three weeks later, she broke out in a rash, complained that her
points hurt, and had swollen glands. This worried Elizabeth, and so she consulted a
conventional medical doctor.
Samantha was diagnosed with rheumatic fever, and the doctor prescribed antibiotic treatment.
Elizabeth had read that antibiotics could damage the immune system, and was reluctant to
give them to her daughter
How can you as a nurse, encourage compliance with long-term antibiotie treatment without
abenating Elizabeth? To what extent does a parent have the night to refuse medical advice for
a child? When are alternative therapies helpful?
Answer and Explanation:
1. As nurses, we can inform you that the use of antibiotics according to medical advice is not dangerous, because the doctor is able to prescribe a correct dose, which must be taken at the correct time intervals, to fight the disease without damaging the immune system . In that case, if the girl takes the medicine exactly as the doctor prescribed, she will have no problems and her body will recover completely.
2. Parents only have the right to refuse medical advice, when such advice is clearly abusive, puts the child at proven risk, or presents experimental treatments without scientific evidence, as it may endanger the child.
3. Alternative therapies are beneficial when they are accompanied by traditional medical treatment, or when they seek to promote relaxation and stress reduction, without trying to fight infections and more serious health problems.

g Would an observational study or an experiment be more appropriate to investigate the effects on fertilizer on plant growth? Explain.
Answer:
The economists typically receive information premised upon the information gathered during controlled studies. A further explanation is provided below.
Explanation:
The investigators typically add particular manipulation throughout the observational investigation and analyze the consequences.The survey was performed here because the investigators simply would be required to examine the influence of fertilizer on the development of plants. Each assistance must be applied.Given the latitudinal differences in sunlight intensity, how might you expect the carrying capacity of a plant species found at the equator to compare with that of a plant species found at high latitudes? Explain your answer
Answer:
The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.

2. Which statement compares the temperatures of the white and black sheets at 1, 2, and 3 minute(s)? The temperature ( is higher for the black paper, is higher for the white paper, is the same for both pieces of paper )
3. What conclusion can be made based on this data? ( the black paper absorb less heat. The white paper absorb less heat. The pieces of paper absorb the same amount of heat. )
Answer:
1. The heat is transferred from the light bulb to the paper.
2. The temperature is higher for the black paper.
3. The white paper absorb less heat.
Explanation:
1. The heat is transferred from the light bulb to the paper.
This is because the light bulb is the source of heat in the experiment. Thus removing the light bulb implies that no heat would flow apart from the ambient heat.
2. The temperature is higher for the black paper.
A black body is a good absorber of heat. So, the temperature of the black paper would be higher compared to that of the white paper.
3. It can be concluded based on this data that: The white paper absorb less heat.
Since white surfaces are good reflectors of heat. Thus the white paper reflects most of the heat from the bulb, while absorbing very little fraction of it.

What is the ethical dilemma associated with randomized controlled studies for suspected causes of disease such as cigarette smoking?
a. The prevalence of disease within the study cannot be controlled.
b. The effect of the disease is too detrimental to the health of those involved within the study to allow them to be voluntarily exposed to a suspected cause of disease.
c. Incidence of disease is often determined to be too low to conduct a randomized controlled trial.
d. It is difficult to establish definitive contributory cause even with a high-quality randomized controlled trial.
Answer:
b. The effect of the disease is too detrimental to the health of those involved within the study to allow them to be voluntarily exposed to a suspected cause of disease.
Explanation:
Randomized controlled studies assess the relationship between cause and effect. There are usually two groups in this study. The first group is the experimental group which is exposed to the treatment or intervention to be assessed while the second group is the control group which is given no treatment or given a placebo.
As it relates to the question, the experimental group is exposed to cigarettes to determine the effect of this exposure. This can have an adverse health effect on the experimental group, hence, this is an ethical dilemma.
Whic type of graph would you use if you wanted to see if one variable had an affect on another variable?
A scatter plot or scattergram chart will show the relationship between two different variables or it can reveal the distribution trends. It should be used when there are many different data points, and you want to highlight similarities in the data set.
Answer:
line
Explanation:
A line graph is used to see if there is a relationship between variables.

(f) Microfilaments, intermediate filaments, microtubules
(g) Microfilaments, microtubules
(h) Microfilaments, intermediate filaments, microtubules
(i) Microtubules, microfilaments
(j) Microtubules
Explanation:
Microtubules (MTs) are dimers of the protein tubulin (alpha- and beta-tubulin subunits) and they are major components of the cytoskeleton. MTs play diverse cellular roles including, mechanical support (cytoskeleton), transport, motility, chromosome segregation, etc. Microfilaments (MFs) are protein filaments that also form part of the cytoskeleton in eukaryotic cells. MFs consist of G-actin monomers assembled in linear actin polymers, and their functions include mechanical support, cytokinesis, changes in cell shape, amoeboid movement, endocytosis and exocytosis, etc. MFs associate with the protein myosin to generate muscle contractions. Actin filaments/MTs assembly from monomeric actin/tubulin is caused due to energy expenditure, where ATP/GTP bound to actin/tubulin is hydrolyzed during polymerization. Finally, intermediate filaments (IFs) are a type of cytoskeletal element composed of a heterogeneous group of structural elements, and they are not found in all eukaryotes. The primary function of the IFs is to contribute to the mechanical support for the plasma membrane where these filaments come into contact with other cells and/or with the extracellular matrix. The IFs are not directly involved in cell movement. All 3 types of cytoskeletal elements (microfilaments, intermediate filaments, microtubules) can be visualized by fluorescence microscopy when cells express chimeric MT/IF/MF.–GFP fusion proteins.
