Why can whales not breathe underwater?
Answers
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.
1. In passive transport, what direction do molecules move?
2. In active transport, what direction do molecules move?
Answers
Answer:
In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.
In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient.
Explanation:
The transfer of molecules from higher concentrations to lower concentrations is an example of passive transport, which does not require any amount of energy.
The movement of molecules from a lower concentration to a higher concentration is referred to as active transport. Active transport requires the application of energy.

What may happen if mitosis doesn't start around the open wound?
Answers
Mitosis is the type of cell division where the daughter cells are exact copies of the parent cell. Mitosis takes place around the open wound area for recovery but if mitosis does not start around the open wound recovery would not take place.
What is Mitosis?
Mitosis is the process of cell division where the parent cell undergoes division to form daughter cells which are exact copies of the parent cell. Mitosis is also known as Equational division. The chromosomal number in the parent cell is exactly same as the daughter cells.
Mitosis is divided into two phases: Interphase and M-phase. The actual cell division takes place in the M-phase. M-phase is divided into four phases which are Prophase, Metaphase, Anaphase, and Telophase. In mitosis, one parent cell gives rise to two daughter cells. Mitosis takes place in all the cells of an organism.
Mitosis is responsible for restoring the cell number back to normal in body.

what is a membrane potential and how is it generated?
Answers
Answer:
Differences in the concentrations of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Typical values of membrane potential are in the range –40 mV to –70 mV. ... These concentration gradients provide the potential energy to drive the formation of the membrane potential.

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.
Answers
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.

Lots of hydroxides (OH) will make a solution
A.acidic B. Basic C. Neutral
Answers
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.
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:

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.

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.
The pancreas is an organ present in some animals. It produces enzymes that are used in the digestive system of the animal. Which cell structure is likely to be abundant inside pancreas cells?
A. Cell walls, because cell walls cannot be digested by enzymes
B. Chloroplasts, because chloroplasts provide the energy for making enzymes
C. Nuclei, because nuclei contain the instructions for synthesizing enzymes
D. Ribosomes, because enzymes are synthesized on ribosomes
Answers
Answer: the answer is D Ribosomes, because enzymes are synthesize on ribosomes
Explanation:
Because we need more protein to be produced in are pancreas
The messenger RNA (mRNA) sequence is read by the ribosome, which then interprets the genetic code into a predetermined string of amino acids. These amino acids then form lengthy chains, which fold to form proteins. Thus, option D is correct.
What is the role of ribosomes in the enzyme formation?Protein synthesis is always carried out by the ribosome, which converts the genetic code produced in mRNA into an amino acid sequence.
Ribosomes carry out the initiation, elongation, and termination of peptide synthesis using metabolic energy, soluble transfer RNA's, and cellular auxiliary proteins.
The biocatalyst, which are proteinaceous in nature, are enzymes. The ribosomes found on the endoplasmic reticulum produce these. A cell's ribosomes are referred to be its “protein factory.”
Therefore, Ribosomes, because enzymes are synthesized on ribosomes.

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.
