Answer:
5. c. active transport of molecules across a membrane
6. b. osmosis
7. d. water entered the cells of the lettuce by osmosis
Explanation:
5. The diffusion of water does not involve the budding of the cell membrane. The production of proteins amino acids and asexual reproduction are unrelated to the movement of molecules across the cell membrane. Therefore, this is active transport of molecules across a membrane.
6. The diffusion of water from a high concentration to a low concentration of water across a selectively permeable membrane is called osmosis. Transpiration is the process by which water leaves plant cells. Active transport requires energy. Capillary action is when water moves as a result of adhesion/cohesion.
7. When water enters the cells by osmosis, the cells become more turgid, making the lettuce crisp.

Explanation:
Lots of hydroxides (OH) will make a solution
A.acidic B. Basic C. Neutral
Answer:
B. Basic
Explanation:
Hydroxide (OH) is an anion with the chemical formula OH-. As the formula implies, it consists of an oxygen atom and a hydrogen atom. The more electronegative oxygen atom shares electrons with the less electronegative hydrogen atom via covalent bonding.
Hydroxide ion dissolves in water to form a very strong base, hence, an aqueous solution that contains lots of hydroxides will be BASIC or ALKALINE. A solution with lots of hydroxide ions is a STRONG BASE.

Which is true about scientific knowledge?
Answer:
Explanation:
It changes as new evidence is found.
An example is the scientific knowledge of climate change. This scientific knowledge is not agreeable across all the world scientists. However as more and more evidence is collected, over time, the understanding of climate change will change and will either refute or corroborate the earlier understanding.
Please help! If gastric protease was put in the intestine, do you think it could still carry out its usual function of digestion? Why or why not?
Answer:
Explanation:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.

Why can whales not breathe underwater?
Answer:
Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. ... After each breath, the blowhole is sealed tightly by strong muscles that surround it, so that water cannot get into the whale or dolphin's lungs.
Glucose and fructose are monosaccharides that have the same chemical formula, C6H12O6. However, they do not react the same chemically. Which of the following generalizations can explain this? (5 points)
a
Monosaccharides serve different cellular functions, and they are only involved in reactions in which they are needed.
b
The atoms of monosaccharides are arranged differently, and the different shape gives each monosaccharide unique properties.
c
Monosaccharides have different properties, but the disaccharides they form when combined with other molecules will have the same properties.
d
The atoms of monosaccharides are arranged similarly, but the monomers from which they are formed have different physical and chemical properties.
Answer:
B
Explanation:
Monosaccharides are the simplest carbohydrates. Although glucose and fructose have the same molecular formula they have different structures or the atoms are arranged differently from each other and this is evident in the way they react, behave and in their properties.
Dr. Naskrecki believes that scientists will eventually identify between 50,000 and 100,000 species in
Gorongosa National Park. Why do you think he suspects there are so many more than the 2,829
species they have already identified living in the park?
Answer:
The reason why Dr Naskrecki thinks he suspects there are so many more than the 2,829 species they have already identified living in the park is because there are many species that has been identified in the world because humans haven’t gotten to most parts of the earth which makes it a lot undiscoverable.
Another one is that the species multiply rapidly and easily.

9. If your cells were used to discover a cure for a disease do you think you should have first given consent for their use? Should you also receive something back if the research makes lots of money. Explain why.
Answer:
If my cells were used to discover a cure for a disease I don't think it would matter to give consent because I would have saved lots of people. I think I should earn just a little bit of money, because they are my cells, but I don't think I should earn a lot or most of it.
Answer:
Yes, you need to give consent because otherwise, they can not have any part of you without consent.
Explanation:
You should expect some money even if it is a small amount to come to you due to you being the one with the cure therefor the scientist or bioglist would have to study them and would go on to trials if they make a vaccine. Always, give consent if you deem it the right choice never by force.
What is the first aid for cramps?
Answer:
Take a hot shower
Massage the cramped area
Yup thats all i know
We all know that any cramp in our muscles is formed due to the secretion of lactic acid . This lactic acid is formed due to our muscles doing anaerobic respiration instead of aerobic respiration . Our muscles require oxygen to break down glucose itn energy and carbon dioxide . But our body muscles wont get this much needed oxygen due to which they will start to do anaerobic respiration where they produce energy without the usage of oxygen . When such a respiration happens lactic acid is secreted in our stomach , which makes our muscles start to form cramps . So we can say that tightness or soreness of muscles due to our muscles lacking oxygen is called as muscle cramps . So , a hot bath will be a very good remedy for cramps as it will let the oxygen pass through the body , thereby completely help the lactic acid turn into energy . When lactic acid breaks down completely to form energy the muscle cramps go away . Another first aid for cramps would be massaging the area with cramps . This will also increase the oxygen flow thereby making the lactic acid change into oxygen due to which the pain will go away . Another remedy for muscle cramps would be hot nor cold pads as they help ease the pain .

In what type of climate do trees produce narrower rings?
cool and dry
warm and wet
cool and wet
warm and dry
Answer:
Cool and dry
Explanation: Trees tend to be sensitive to climates, so when the conditions are good the trees grows faster which results in wider growth rings and in poor conditions the tree grows slower which results in it laying down less tissue and therefore a narrower ring size. Drought and a blizzard can also cause narrower ring too. Actually, a cool way to find out if the climate conditions were good is to measure the rings of a tree every month each year. If the rings were consistently the same then you know the climate stayed pretty much the same and etc.

The lytic and the lysogenic cycles are the two methods that bacteriophages reproduce. They both begin with a bacterium that has been infected with bacteriophage DNA.
Lytic:
The phage DNA reinstructs ribosomes and the bacterium begins producing many bacteriophages.The bacterium eventually lyses and releases the bacteriophages into the environmentLysogenic:
The phage DNA is incorporated into the bacterium's chromosome.The bacterium eventually duplicates this DNA when it undergoes fission, producing two infected daughter cells.Eventually, the phage DNA will be read by the bacterium and it will go into the lytic cycle, described above.To sum it up, the lytic cycle ends the bacterium's life by producing offspring, yet the lysogenic cycle allows for multiple bacteria to divide and eventually undergo the lytic cycle.
