Photosynthesis is a process that makes glucose (sugar) from carbon dioxide and water with help from the sun using the pigment chlorophyll.

The ongoing process of cell growth, division, and replacement is called the cell cycle.

Photosynthesis captures energy from the sun using the pigment chlorophyll.

Cellular respiration makes energy in the form of ATP (adenosine triphosphate), and waste products are carbon dioxide and water.

Anaerobic respiration occurs without oxygen.

Coiled and condensed DNA is called a chromosome.

In the cell division process known as mitosis, a single cell splits into two completely identical daughter cells.

Mitosis occurs in eukaryotic cells, which include cells of plants, animals, and fungi.

Mitosis produces two daughter cells, and they are identical to each other and to the parent cell.

The four stages of mitosis are:

Prophase

Metaphase

Anaphase

Telophase

The loss of 131 cells in the development of C. elegans is due to the process of apoptosis, a programmed cell death mechanism.

The process by which an embryo of C. elegans loses 131 cells is apoptosis. Apoptosis is a programmed cell death mechanism that occurs naturally during development to eliminate unnecessary or excess cells.

Explanation:

Answer:

The invisible mixture of gases that surrounds Earth is known as air. Most species require important substances found in air, such as oxygen and nitrogen, to survive.

The student can ensure that the potential energy of the marble remains constant, and any changes in kinetic energy can be attributed to the marble's speed and mass.

If the student wants to change the track so that the potential energy of the marble remains constant from point 1 to 5, then they would need to make sure that the height of the track remains the same throughout. This can be achieved by keeping the track level or having a gradual slope.

When an object is raised to a certain height, it gains potential energy due to its position in a gravitational field. The higher the object is raised, the more potential energy it gains. Conversely, when the object is lowered, it loses potential energy. Therefore, if the height of the track is kept constant, the potential energy of the marble will remain constant as it rolls from point 1 to 5.

The student can achieve this by adjusting the slope of the track so that it remains level or has a consistent slope from point 1 to 5. They can also add supports or other structures to ensure that the track remains at a constant height throughout its length.

Ocean acidification is a phenomenon that has become prevalent in the last few decades. It is caused by carbon dioxide in the atmosphere, which is dissolved in seawater to form carbonic acid, reducing pH levels in the ocean. Coral and pteropod shells, which are made of calcium carbonate, are some of the most vulnerable organisms to this process.

As carbon dioxide dissolves in seawater, it causes a decrease in pH levels, which in turn causes calcium carbonate to dissolve at a faster rate. Since carbon dioxide is more soluble in cold water than warm water, the organisms that will be the first to be affected by ocean acidification are pteropods.

The ability of coral and pteropods to build their shells is jeopardized as ocean acidification increases. If this process persists, the integrity of coral reefs and pteropod shells will be destroyed. Since pteropods are more vulnerable to ocean acidification than corals, the situation has more dire implications for them.

Answer:

Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.

Explanation:

Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.

Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.

Elimination by aspect strategy

Anthony is most likely using the elimination by aspects strategy. Option b is correct.

This decision-making strategy involves narrowing down options by evaluating them one by one based on specific aspects or criteria. Anthony is eliminating phones that don't meet his criteria, which is a characteristic of the elimination by aspects strategy. This approach allows him to focus on the most important aspects and make a decision based on those criteria.

The fast and frugal heuristic (option A) is a decision-making strategy that involves quickly making judgments based on a limited set of cues, which might not align with Anthony's process of systematically eliminating options based on criteria.

The theory of bounded rationality (option C) is a concept that acknowledges that individuals make decisions within limits, considering factors like time, information, and cognitive capacity. While related, it doesn't directly describe the specific strategy Anthony is using to narrow down his phone choices.

The additive strategy (option D) involves assigning scores or values to different options and adding them up to make a decision. This doesn't align with the description of Anthony eliminating options based on criteria.

Therefore, the elimination by aspects strategy best describes Anthony's approach of narrowing down his phone choices by eliminating those that don't meet specific criteria, allowing him to make a more informed decision.

Answer:

Hybrid

Explanation:

An HYBRID is a product of crossing two purebred organisms for a particular trait. In more genetic terms, hybrid contains two different alleles in its genotype; one from each different parent. For example, crossing a horse and a donkey will result in a mule.

Based on the above explanation of a hybrid organism, one would realize that in terms of genotype, an hybrid is usually heterozygous for the involved gene. That is, the genotype will contain one allele from each parent e.g. Aa or Dd. For instance, when crossing two purebred organisms (red, RR and white, rr) for color in four o'clock plants, the resulting organisms are heterozygous pink (Rr) and can be said to be a HYBRID.

All immune cells, including neutrophils, dendritic cells, and macrophages, are capable of phagocytosis—the process of ingesting and digesting pathogens, cellular debris, and other foreign substances.

Inflammation responses to infections and tissue injury are primarily mediated by neutrophils and macrophages, two important components of the innate system. Inflammation responses have the potential to initiate the pathogenesis of a wide range of diseases, including autoimmune disorders and inflammatory disorders, if they become out of control.

Neutrophils get APCs-like attributes. Dendritic cells, or DCs, are the primary APCs that are capable of triggering a naive T-cell response. Macrophages and B cells additionally express MHC-II and costimulatory atoms and are equipped for enacting effector or memory CD4+ Th cells.

The preserved weasels are estimated to be approximately 7163 years old.

To determine the age of the preserved weasels, we need to use the concept of radioactive decay and the half-life of carbon-14.

Carbon-14 (14C) is a radioactive isotope of carbon that undergoes decay over time. The half-life of carbon-14 is approximately 5730 years, which means that after 5730 years, half of the initial amount of carbon-14 will have decayed.

Let's calculate the number of half-lives that have occurred based on the difference in carbon-14 between the live and preserved weasels:

Initial amount of carbon-14 in live weasels = 29 g

Amount of carbon-14 in preserved weasels = 10.9 g

The difference in carbon-14 between the two is: 29 g - 10.9 g = 18.1 g

Since each half-life reduces the amount of carbon-14 by half, we can calculate the number of half-lives that have occurred by dividing the difference in carbon-14 by half the initial amount:

Number of half-lives = (Difference in carbon-14) / (Half the initial amount)

Number of half-lives = 18.1 g / (29 g / 2) ≈ 1.25

Now, we multiply the number of half-lives by the half-life of carbon-14 to find the time elapsed:

Age of preserved weasels = Number of half-lives * Half-life of carbon-14

Age of preserved weasels = 1.25 * 5730 years ≈ 7163 years
