Answer:

C the data the profile symptoms

Explanation:

The team that required prior to drawing the conclusion related to the case should be option c. where the profile shows the symptoms of various patients.

Reasons for excess sweating and kidney stones:

The main reason of excessive sweating is the dehydration that means we are not drinking sufficient water due to which the risk of the kidney stones should be increased.

If the protein diet is high, or there is high salt intake, or high sugar intake due to this also the stones chances are high.

Therefore, the option c is correct.

The statement that describes the similarity between photosynthesis and cellular respiration is that both include reactions that transform energy.

PHOTOSYNTHESIS:

Photosynthesis is the process by which green plants obtain food using energy from sunlight.

CELLULAR RESPIRATION:

Cellular respiration is the process by which living organisms obtain energy (ATP) by breaking down food molecules in their cells.

Cellular respiration and photosynthesis are both metabolic processes that transform energy.

Cellular respiration transforms energy in food molecules to usable energy by cells while photosynthesis transforms solar energy to chemical energy.

Why postharvest physiology is important to maintain sustainable food supply on this planet. Please give named examples and discuss various biological factors associated with produce deterioration after harvest

Answers

Answer:

Postharvest physiology plays a fundamental role in extending the shelf-life and quality of plant products. An example of postharvest physiology methodologies is by reducing the temperature to improve shelf-life before consumption

Explanation:

Postharvest physiology refers to the methodologies used for extending shelf-life and quality, thus being a critical issue in food systems. Postharvest approaches include chemical treatments, temperature reduction, cleaning and disinfection methods, etc. Crop varieties are genetically selected in order to maintain nutritional qualities of stored seeds for a long time after harvest. These seeds are also controlled during storage by using postharvest handling practices (e.g., chemical and enzyme inhibitors that extend shelf life).

Answer and Explanation:

The cell looks like a prokaryotic cell. A prokaryotic cell might be recognized by the presence of flagellates used to move (the four long filaments located posterior to the cell). There are also many pili surrounding the cell wall (the small little filaments). There are almost no organelles. There is a circular DNI molecule concentrated in a nucleoid (which seems to be the grey oval in the middle of the cell). Prokaryotic cells also have different compartments that depend on the type of cells, such as chlorosome, carboxysome, phycobilisome, and others (which might be the dark spiral circle in the anterior part of the cell). Two differences with the cell of an onion peel are that the onion peel cell has its genetic material surrounded and protected by the nucleus membrane, whereas the prokaryotic cell lacks a delimitated nucleus. Also, the onion peel cell has a hexagonal shape and lacks flagellates and pili, unlike the prokaryotic cell, which uses the to move. The onion peel is a multicellular structure, while the prokaryote is a one-celled organism. There should always be a cover glass over the cell or tissue we are looking at. Fasten the slide with the stage clips. Move the lens carefully in order not to damage it or the slide. Do not touch or clean the lens with the fingers and try not to stain them.  

PLEASE HELP ME WITH 10 and 11!! :(

Answer:

Please find the answers to numbers 10 and 11 of the attached image below.

Explanation:

10. This question lists the stages of mitosis namely: prophase, metaphase, anaphase, and telophase. The major events that take place in each of these stages are as follows:

A) PROPHASE:

- the supercoiled chromosomes known as chromatin begins to condense making it visible.

- spindle begins to emerge from the centrosome organelle.

- Nuclear envelope begins to break down in order to expose the chromosomes in the nucleus.

B) METAPHASE:

- The chromosome are aligned at the cell plate i.e. the equator/middle of the cell.

C) ANAPHASE:

- The sister chromatids of each chromosome i.e. replicated chromosomes are pulled apart at the centromere by spindle microtubules to the opposite poles of the cell.

D) TELOPHASE:

- Chromosomes at opposite poles begin to decondense into chromatin.

- The nuclear envelope reforms around the chromosomes

11) Cytokinesis is the process that occurs after mitosis (nuclear division). It is the process whereby the cell whose chromosomes are now separated into opposite poles divide into two. In other words, a cell divides into two in the cytokinesis stage.

Fixed sample size:

In this fixed sample size the data is studied and checked in order to find a relationship. The benefits it is easy to produce, and with it less reliable outcomes can be given.

Sequential procedures:

→Sequential procedures helps while we are collecting the data.

→At an interim analysis, data collection can be stopped whenever the results are convincing enough to conclude an effect is present.

→Or otherwise the more data can be collected, or if needed the study can be terminated whenever it is extremely unlikely the predicted effect will be observed if data collection would be continued.

→In this two or more blocks of different sizes are prepared for testing.

→Pros being it provides better results and is less time taking, as we can stop once the relation is seen, con being it is difficult to perform.

| Suggest two environmental factors that enable pine trees to photosynthesise in spring and summer in
Switzerland, but not in winter.

Answers

Answer: Temperature and light

Explanation:

In winter, day length is shorter than in spring/summer and the sun does not rise as high in the sky. There is also more cloud cover, fog and snow to reduce access and intensity of light.

Colder temperatures reduce metabolic activity, and at temperatures below zero, water uptake is prevented, which reduces transport of nutrients, and icing of needles and snow cover reduce access to carbon dioxide.

In spring/summer sunlight is more readily available, temperatures more conducive to carbon dioxide uptake and transpiration.

The  two environmental factors are Temperature and light

The following information should be considered:

In winter, day length is less than in spring/summer and the sun does not rise as high in the sky. There is also more cloud cover, fog and snow to reduce access and intensity of light. Colder temperatures decreased metabolic activity, and at temperatures below zero, water uptake should be prevented, which decreased transport of nutrients.

Which biomolecule provides cells with the most energy per gram?

lipids

proteins

nucleic acids

carbohydrates

Answers

Answer:

carbohydrates

Explanation:

Among the choices above, it is "carbohydrates" that provide the most energy per gram. Although both carbohydrates and proteins provide 4 calories per gram, carbohydrates contain the most number of glucose, which is being used in order for the body to have energy. So, if you want a quick way to become energetic, it is best to eat "healthy carbohydrates" than proteins.

Around 60% of proteins are converted into glucose while 100% of carbohydrates are converted into glucose. Therefore, carbohydrates provides more energy.

1. Which image represents the flow of a longshore current in relation to a sandy beach?​

Answers

Answer: Option C

Explanation:

When waves of water approach the beach, they do so as an angle because they have been slowed down by the first parts of the beach that they have encountered.

When they hit the beach at an angle, they come back to the water and keep doing so like the movement shown in option D. This constant motion moves the sand and other particles on the beach progressively and the current that does so is the Longshore current which moves parallel to the coastline.
