If you put a red blood cell into a glass of pure water, what would happen?
When red blood cells are placed into a solution with higher concentration as compared to their contents (eg pure water) will gain water by osmosis, burst and swell up.
Osmosis is termed as the net movement of water across with semipermeable membrane. This across of membrane, water will moves from an area of higher concentration to lower concentration.
If red blood cells are placed in water, then water enters the cell by osmosis. Because the membrane is quite very weak the cell will burst as the volume and therefore the pressure in the cell will increases. Red blood cells shrink when it placed in the concentrated solutions of sugar as water moves out of them by the osmosis.

An atom of iron has an atomic number of 26 and a mass number of 56. How many protons plus neutrons are in the nucleus?.
The number of protons in an atom is also referred to as the atomic number, so an atom of iron has 26 protons in its nucleus. The mass number of an atom is the sum of the number of protons and neutrons in the nucleus. So, to find the number of neutrons in the atom, we can subtract the number of protons (26) from the mass number (56):
56 - 26 = 30 neutrons.
So, the number of protons plus neutrons in the nucleus is:
26 protons + 30 neutrons = 56.
What are two characteristics of r-selected species?
These characteristics of R-selected species perfectly:
Rapid development. High reproductive rate. Early reproductive age. Small body size. One reproductive cycle. Short lifespan. Poor competitive ability. High mortality of offspring.What is r-selected species
r-selected species, also called r-strategist, species whose populations are governed by their biotic potential (maximum reproductive capacity, r). Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O. Wilson; K-selected species—that is, species whose population sizes fluctuate at or near their carrying capacity (K)—make up the second strategy.
The production of numerous small offspring followed by exponential population growth is the defining characteristic of r-selected species. They require short gestation periods, mature quickly (and thus require little or no parental care), and possess short life spans. Unlike K-selected species, members of this group are capable of reproduction at a relatively young age; however, many offspring die before they reach reproductive age.

True/false
False. Cytoplasm is not randomly distributed to haploid cells.
Haploid cells refer to cells that have a single set of chromosomes, as opposed to diploid cells that have two sets. The process of cell division, called mitosis, is responsible for the distribution of cytoplasm and chromosomes to the new cells. The cytoplasm and chromosomes are divided equally between the two daughter cells. The process is highly regulated and orchestrated to ensure that the cells have the correct amount of cytoplasm and chromosomes to function properly. It's important to note that, in some cases, in some organisms, such as fungi, there is a process called plasmogamy, where cells fuse, but their nuclei do not, resulting in a cell with multiple nuclei but a single cytoplasm.

Commercial meat tenderizer often contain papain, a proteolytic (protein-digeting) enzyme. How might uch product make meat more tender?
The fruit papaya includes the enzyme papain, which aids in the breakdown of proteins by severing the bonds between amino acids, gradually softening the meat.
As a result, it is perfect for use as a meat tenderizer because its enzyme gives meat a softer texture and more flavor. Meat would become more soft thanks to a protein-digesting enzyme that would reduce lengthy, fibrous protein chains into smaller protein chains. An enzyme will accomplish the same type of cutting, but on a smaller scale, just as repeatedly piercing a tough piece of meat with a fine blade will cut long protein strands into shorter, more delicate fibres.
Papaya and a few other plants contain the protein-cleaving enzyme known as papain. Complex molecules called enzymes are created by living things to catalyze (fast-track) chemical reactions inside of cells.

What is the number of nitrogen molecules that reacted with excess hydrogen to make 2 x 1010 molecules of ammonia?.
The number of nitrogen molecules that react with excess hydrogen to produce 2x10^10 ammonia molecules is 1×10¹⁰.
Stoichiometry is the calculation of a balanced chemical equation that determines the ratio between reactants and products in a chemical reaction.
Equilibrium in chemical equations obeys conservation principles and Dalton's model of the atom, such as the Law of Conservation of Mass, which states that:
mass of reactants = mass of products
In this sense, the equation must have equal weight on both sides of the equation.
In terms of reactions, both are in equilibrium 3H₂ + N2 ⟷ 2 NH₃
If 1 molecule of nitrogen produces 2 molecules of ammonia
2 x 10¹⁰ ammonia molecules will be produced if 2 x 10¹⁰ × 1/2= 1 × 10¹⁰ molecules.

The letterDear body,
I am writing to remind you of the crucial role I, Meiosis, play in your function and ability to carry out life. Without me, the process of creating genetically diverse gametes, the cells responsible for fertilization, would not be possible.
As you may know, my primary function is to reduce the number of chromosomes in a cell from the diploid number to the haploid number. This process, also known as cell division, is essential for the formation of healthy and viable gametes. Without the reduction of chromosomes, fertilization would not occur and the continuation of life would be impossible.
During my process, genetic diversity is also increased through the process of crossing-over, in which genes from different chromosomes can be exchanged. This leads to the formation of unique combinations of genetic information in each gamete, which is vital for the survival of future generations.
In short, my role in your body is to ensure the creation of healthy and genetically diverse gametes through the reduction of chromosomes and the process of crossing-over.
