Answer:
Options B and D
Explanation:
In animals, gaseous exchange takes place in the alveoli in the lungs. Generally, animals breath-out (exhale) carbon dioxide and breath-in (inhale) oxygen. Thus, carbon moves from the blood in the form of carbon dioxide into the alveoli in the lungs while the oxygen inhaled moves from the alveoli in the lungs to the blood where it is transported round the body as oxyhaemoglobin.
Answer:
B. Carbon moves from the blood into the lungs.
D. Oxygen moves from the lungs into the blood.
Explanation:
During respiration, humans take in air which contains oxygen and the oxygen gas then moves from the lungs into the blood . The blood helps to distribute the oxygen to other parts of the body for their proper functioning.
When we breathe out, we give out carbon dioxide as a result of the carbon which is taken up from the blood into the lungs and subsequently given out to be used by plants for their photosynthetic processes.
What does the formula ´220´ -your age tell you?
Answer:
The formula "220 - age" is the estimate of the maximum heart rate.
Explanation:
The heart rate is determined by the number of heartbeats per minute, which is a relatively easy parameter to measure.
In an adult, the heart rate is in the range of 60 and 100 beats per minute, under normal conditions. The maximum heart rate (MHR) is the value of beats per minute that should not be exceeded during the practice of physical activity, in order not to produce damage to the heart or cardiovascular system. The formula is:
MHR = 220 - age
The use of MHR has been very controversial, mainly because the formula provides an estimated value, but there is not enough scientific data available.
Currently, it is often used to estimate and dose the physical activity that a person can perform safely.

Compare and contrast the responsibilities and skills required for production jobs versus service jobs in the food service industry. What is the essential difference between these two areas in the industry? Based on your inherent characteristics and skill set, which do you feel you are better suited for and why?
Answer:
Explanation:
The Food service industry is an industry responsible for making food and selling the same food for public consumption.
Similarities of the responsibilities and skills required for production jobs versus service jobs in the foodservice industry:
1) Both jobs require the need to have the knowledge to function well.
2) Both jobs need workers to know food safety rules.
3) Both jobs require workers that are competent to handle customers and give them a good experience.
4) They are both charged with the responsibility of operating in a safe environment.
5) They must both have knowledge of food preparation.
Differences in the responsibilities and skills required for production jobs versus service jobs in the foodservice industry:
1) Production jobs require more food making skills compared to service jobs.
2) Service jobs require more customer handling skills compared to food production jobs.
The essential difference between these two areas in the industry is:
Production jobs in the foodservice industry handle the aspect of food or drink preparation to meet the quality required for consumption. While food service jobs are about jobs in the foodservice industry that workers in the department need to directly have contacts with customers thereby ensuring customers have an excellent dining experience.
Based on your inherent characteristics and skill set, which do you feel you are better suited for and why?
I'm better suited for service jobs because of my customer handling skill, my ability to pay attention to details, communication skills, and hardworking skills.

Horatio is may be suffering from Metabolic acidosis.
What is metabolic acidosis?Metabolic acidosis is a condition in which the body's fluids contain too much acid.When the body produces too much acid, metabolic acidosis occurs. It can also happen if the kidneys are unable to excrete enough acid from the body.Causes of Metabolic acidosis:-Diabetic acidosis (also known as diabetic ketoacidosis or DKA) occurs when acidic molecules called ketone bodies accumulate due to uncontrolled diabetes.
The removal of too much sodium bicarbonate from the body, as can happen with severe diarrhoea, causes hyperchloremic acidosis.Kidney disease is a condition that affects the kidneys (uremia, distal renal tubular acidosis or proximal renal tubular acidosis).Lactic acidosis is a condition in which the body produces too much lactate.Aspirin, ethylene glycol (found in antifreeze), or methanol poisoning.Dehydration is a serious problem.Hence the correct option is C.

They are immobile.
They are autotrophs.
Answer:
The answer is
* they are eukaryotic
* they contain chloroplasts
* they are immobile
Hope I helped!!!
Explanation:
Plant cells are eukaryotic organisms. They have some features which makes them unique from other organisms. These include presence of chloroplast, immobile nature, and autotrophic mode of nutrition. Thus, the correct options are B, C, and D.
What are plant cells?Plant cells are the multicellular eukaryotic organisms. These are eukaryotic as they contain double-membranous structures and a well-defined nucleus.
Plant cells contain chloroplasts which perform photosynthesis. Photosynthesis is the process by which plants synthesize their own food by the help of sunlight, carbon dioxide and water. Chloroplast is absent in animal cells.
Plant cells are immobile because they do not have any locomotory organelle on their surface which can cause movement. Plants are anchored deep into the soil with the help of their roots.
Plants show autotrophic mode of nutrition as they can prepare their own food by the method of photosynthesis.
Therefore, the correct options are B, C, and D.

What is the function of the blood-brain barrier?
preventing blood loss during injury
O regulating blood flow through the brain
O keeping brain blood separate from body blood
O keeping foreign particles out of the brain
Answer:
The correct answer is - keeping foreign particles out of the brain
Explanation:
The blood-brain barrier or BBB is the barrier of endothelial cells that is highly selective and semipermeable in nature that allows selective molecules like certain lipids, gas, and water and prevent other solutes and pathogens, toxins, and infectious agents from circulating blood between capillaries and brain. However, including specific gases and nutrients can cross this barrier.
Thus, the correct answer is - keeping foreign particles out of the brain
