Consider the following experiment. A plant is set in one corner of a box. A top is put on the box so that the hole in the top is opposite to the plant.
Over the next week, the plant in the box should:
grow downward
grow away from the hole
bend and grow towards the hole
die for lack of air
Answer:
It will bend and grow towards the hole because the sunlight will shine through the hole and the plant will sense it so it will grow towards the light. I hope I could help you :)

Explain how the tructure of a cell allow localization of reaction, protection from reactive molecule, and greater efficiency of cellular procee than a bacterial cell
A eukaryotic cell's structure allows for the localization of reactions because there are areas within the cell where particular enzymes colocalize.
Structural barriers are also used to protect against reactive molecules, and the division of work in this cell allows for greater efficiency of cellular processes than in a bacterial cell. In a eukaryotic cell, the phrase "subdivision of work" refers to the existence of several cell compartments, such as those connected to certain organelles that offer an appropriate medium for carrying out specific reactions, such as the presence of hydrolytic enzymes in lysosomes. As a result, according to the findings, division of labour is essential for eukaryotic cells to carry out various activities, which translates to greater metabolic efficiency when compared to bacteria.

How do oxygen and carbon dioxide play different roles in the ocean?
In the ocean, For respiration, marine organisms use oxygen, which converts carbohydrates into energy and produces carbon dioxide and water as byproducts.
For marine life, dissolved oxygen and carbon dioxide are essential. Through the process of photosynthesis, marine plants utilize dissolved carbon dioxide, sunlight, and water to produce carbohydrates. The water gets oxygen from this process. All marine organisms respire with oxygen, which breaks down carbohydrates into energy and produces carbon dioxide and water as byproducts. These organs are utilized by fish and other marine animals with gills to extract oxygen from seawater.

One similarity and one difference between hydrolysis and carbonation.
One similarity between hydrolysis and carbonation is that they are both chemical reactions that involve the addition of water to a compound.
One difference between hydrolysis and carbonation is that hydrolysis involves the breakdown of a compound into smaller molecules through the addition of a water molecule, whereas carbonation involves the addition of carbon dioxide to a compound. Hydrolysis is a chemical reaction that occurs when a compound reacts with water, whereas carbonation is a chemical reaction that occurs when a compound reacts with carbon dioxide.

Did those who were successful in Round One survive equally well when others were competing for food at the same dish during Round Two
No, those who were successful in Round One will not be successful in Round Two since there will be increased competition.
In the pursuit of a single, unshareable aim, competition is a contest between two or more parties in which one side gains an advantage over the other (an example of which is a zero-sum game). Humans, social and economic organisations, and living things are all competing entities. It provides people a variety of employers and working settings while also creating jobs.
Additionally, competition lessens the need for government intervention through business regulation. Consumers, society, and individual liberty all benefit from a healthy, competitive free market. Studies show that competition can promote focus, effort, and learning. A student may be motivated to work significantly harder on their homework by the social pressure of competing with other students.

Meiosis produces our sex cells or gametes. (eggs in females and sperm in males).
O true
O false
Answer:
True
Explanation:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
True. Meiosis produces our sex cells or gametes.
What is meiosis?Meiosis is a type of cell division that occurs in sexually reproducing organisms to produce haploid gametes (sperm and eggs) with half the number of chromosomes as the parent cell. It involves two successive cell divisions, known as meiosis I and meiosis II, each of which consists of a series of stages, including prophase, metaphase, anaphase, and telophase.
During meiosis I, homologous chromosomes pair up and exchange genetic information in a process called crossing-over, which increases genetic diversity. The paired homologous chromosomes then separate and move to opposite poles of the cell, resulting in two daughter cells that have half the number of chromosomes as the parent cell.
In meiosis II, the sister chromatids of each chromosome separate, resulting in four haploid daughter cells with unique combinations of genetic information.

What is a substitution deletion and insertion point mutation?
Insertion mutation occurs when an extra base pair is added to a sequence of bases.
In general, a Point mutation refers to alteration in a single base pair of DNA by substitution, deletion, or insertion of a single nitrogenous base. Most common example of point mutation is sickle cell anemia. that consists of mutation in a single base pair in the beta-globin chain of hemoglobin pigment in the blood cells. Thus, An insertion can involve the addition of any number of nucleotides, that can be a single nucleotide or an entire piece of a chromosome.
An insertion is a point mutation in which one or more base pairs is added to a DNA sequence. Point mutations is further divided into silent mutations, missense mutations, and nonsense mutations.

The phrase "survival of the fittest" refers to the process of natural selection, a mechanism that promotes evolutionary development. Natural selection works by favoring individuals who are more suited to a particular set of environmental conditions over those who are not.
Because it brings new variety into the population, mutation is the only method of evolution identified that increases the quantity of genetic variation. Genetic drift is the loss of genetic variation caused by chance over time.

If the cell's external environment becomes very WATERY (dilute) then the outside of the cell will have a higher water concentration. We say the cell environment is HYPOTONIC. Water will diffuse in this case.
Which way is the water going to diffuse?
The cell's exterior cell will contain higher water percentage if the external environment of the cell becomes particularly watery (dilute). The cell milieu is referred to as hypotonic. In this situation, water will diffuse.
A hypotonic solution is what is it?Any external solution with a low solute content and a high water concentration in comparison to body fluids is referred to as a hypotonic therapeutic solution. There is a net transfer of water first from solution through into body in hypotonic solutions.
Has hypotonic water gained?When a cell is in a concentrated solution, water goes out of the cytoplasm when both solutions equal isotonic because the workaround has a greater moisture content than the cell cytosol. When cells are submerged in a hypotonic solution, their surfaces will absorb water.
