WHICH OF THE FOLLOWING CONTAINS A CARBOXYL AND AN AMINO GROUP?

Answer:

A. Competition can limit or deplete resources

Final answer:

Competition for abiotic and biotic resources can limit or deplete these resources, affecting their availability in an ecosystem. This can result in harm to competing organisms, influence community dynamics, and alter species distribution.

Explanation:

When organisms and populations compete for abiotic and biotic resources, the impact can be quite significant. Competition can limit or deplete resources, which affects the availability of these resources to both the competing organisms and others in the ecosystem. For instance, plants competing for sunlight, water, and nutrients can reduce the availability of these resources for other species. This competition can harm one or both of the competing organisms, particularly if they are of the same species (intraspecific competition) or of different species (interspecific competition).

An invasive species like kudzu, by competing for light, can outcompete and thus limit the growth of trees. This is an example of how competition can lead to ecological imbalances. In the broader picture, competition impacts not just the individuals directly involved but can also affect community dynamics and the distribution of various species in a habitat.

Considering the options provided, the correct answer is A. Competition can limit or deplete resources.

Explanation:

the scientist add more bacteria to gel A.

Answer:

B. They live in conditions similar to those likely found on other planets.

Explanation:

Archaebacteria involve those bacteria that live in extreme conditions. For instance, halophiles are those species of organisms that live in extreme salty conditions. Archaebacteria are obligate anaerobes that do not require oxygen for its respiration.

Scientists are not sure of the presence of oxygen in other planet and studying the possibility of archaebacteria existing in other planet is higher than other organisms because other higher organisms require proper environment condition for their survival.  

Answer:

C. Photosynthesis

Explanation:

Answer:

The correct option is less.

Explanation:

outside an organism's body.

A hypotonic environment can be described as an environment in which the amount of solvent is more outside the cell as compared to the inside of the cell. The amount of solutes is more inside the cell. Hence, water tends to move inwards by osmosis in such an environment.

An isotonic environment can be described as an environment where the concentration of solutes and solvents is the same inside and outside of a cell.

When paramecium caudatum would be in a hypotonic environment, its contractile vacuole will be more active to pump the excess water. In an isotonic environment, there will be no or very less water for the paramecium to pump out of the body. Hence, contractile vacuole will be less active.

A Paramecium caudatum's contractile vacuole becomes less active when the organism moves from a hypotonic to an isotonic environment. This is because in an isotonic environment, there is no net movement of water, so the need for the vacuole to pump out excess water is diminished.

When a Paramecium caudatum moves from a hypotonic to an isotonic environment, its contractile vacuole would become less active since the water concentration inside and outside the cell will be equal, thus, eliminating the need for the vacuole to remove excess water. In a hypotonic environment, water molecules move into the paramecium due to osmosis, causing the organism to swell. As a response, the paramecium's contractile vacuole pumps out water to prevent the cell from bursting. However, in an isotonic condition, the relative concentrations of solute and solvent are equal on both sides of the membrane, which means that there is no net movement of water. Therefore, the contractile vacuole in the paramecium does not need to be as active in pumping water out of the cell.

Final answer:

The number of cells produced in a week can be calculated using the formula 2^n, where n is the number of generations. Since a plant cell completes the cell cycle in 24 hours, the number of cells produced in a week would be 128 cells.

Explanation:

The number of cells produced in a week can be calculated using the formula 2^n, where n is the number of generations, and each generation represents a 24-hour cell cycle. Since a plant cell completes the cell cycle in 24 hours, we can assume that each day is equivalent to one generation. Therefore, the number of cells produced in a week would be 2^7, which equals 128 cells.

Explanation: All of it is in gamete formation. Meaning, it is going through a gamete formation which also means that pairs of alleles that are for different traits, segregate. They move on independently from one another, never touching.

For your question, It's incomplete dominance which is when cases with one allele isn't complete to be dominant over another allele. It's all got to come together in order for it to become a strong and dominant allele, or else it won't be complete and won't become and do what it has to.

I hope this help you and I hope that I gave you what you wanted/needed for this question.

Final answer:

Two inheritance patterns that differ from simple dominance are incomplete dominance, where neither allele is completely dominant resulting in a blended phenotype, and codominance, where both alleles are fully expressed in the phenotype.

Explanation:

Complex Inheritance Patterns

Not all traits follow the simple dominance inheritance pattern discovered by Mendel. Beyond simple dominance, two other inheritance patterns are incomplete dominance and codominance.

Incomplete Dominance

In incomplete dominance, the phenotype of the heterozygotes is somewhere between the phenotypes of the two homozygous parents. This means that neither allele is fully dominant. A classic example of this is the snapdragon flower, where the cross between a red flower (RR) and a white flower (rr) results in offspring with pink flowers (Rr), a blend of red and white.

Codominance

In codominance, both alleles in the genotype are fully expressed, leading to offspring with a phenotype that is neither dominant nor recessive, but a combination of both. An example of codominance is seen in human blood types, where the A and B alleles are codominant and can result in a blood type of AB.

Answer:

All

Explanation:

All organisms require some sort of oxygen to survive. Fish have gills that pull the oxygen from the water.

Answer:

your answer should be A. bias

The answer is option A "bias." A scientist bias is a opinion on something or someone so in this case a scientist bias on a experiment can effect the experimental results because of what the scientist think is correct so the answer would be option A. It's not option B because curiosity would most likely cause you to test your hypothesis with a experiment. It's not option C because inductive reasoning is supplying evidence for the truth of the conclusion. It's also not option B because deductive reasoning is the opposite of inductive reasoning.

Answer:

A

Explanation:

the Giant impact hypothesis formed when an object smashed into early Earth.

Answer:

Fission Hypothesis

Explanation:

This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.

This theory was thought possible since the Moon's composition resembles that of the Earth's mantle and a rapidly spinning Earth could have cast off the Moon from its outer layers.

However, the present-day Earth-Moon system should contain "fossil evidence" of this rapid spin and it does not. Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received

Answer:

B. It becomes a positive ion.

Explanation:

The number of electrons and protons is eleven in sodium. After sodium (Na) has transferred its electron to the chlorine atom (Cl) it becomes a positively charged ion. This is because as electrons are negatively charged, losing of an electron will increase the number of protons (i.e 11) as compared to the number of electrons (i.e 10) in sodium (Na) atom. Hence, a positive charge will be acquired by the sodium (Na) ions.

Answer:

The correct option is A.

Explanation:

Alligators generally feed on variety of foods, such as small amphibians, birds, fish etc. To catch these preys, alligators usually disguise by immersing all their bodies inside water with only their eyes and noses showing. They will stay perfectly still in that position until a prey come along, then they will quickly attack the prey.

Alligators are quick and efficient predators. This technique that the alligators used to catch their preys enhances their survival and competition for food.  

In addition, alligators depends on their external environments to regulate their body temperature. They can use sun as well as migration to warmer water to regulate their body temperature.

Answer/Explanation :

A heterozygous cat has a genotype Hh

A hairless cat has a genotype hh

When crossed, the results could be any of the following:

Hh (with hair)

hh (hairless)

There is a 50:50 chance or 1: 1 ratio that the offspring will have hair.

Final answer:

In a genetic cross involving cats where hair is dominant over hairlessness, a heterozygous male cat (Hh) mated with a hairless female cat (hh) results in offspring that are predicted to have a 1:1 ratio of haired (Hh) to hairless (hh) genotypes.

Explanation:

The question regards a genetic cross concerning hairlessness in cats, a trait determined by a single gene with two alleles: hair (H) is dominant over no hair (h). When a heterozygous male cat (Hh) is mated with a hairless (hh) female cat, we are examining a simple Mendelian cross to determine the offspring's potential genotypes.

The parents' genotypes in this scenario are as follows:

This cross results in a Predicted offspring phenotype ratio of 1:1, where 50% of the offspring are expected to be heterozygous with hair (Hh) and 50% are expected to be hairless (hh).

Answer:

Surface tension due to cohesion

Explanation:

Water molecules are polar meaning they have dipoles. The hydrogen end is partially positive while the oxygen end is partially negative. This is because oxygen with high atomic mass attracting most of the molecule's electron cloud to its end.

Due to this phenomenon water molecules act like little magnets that attract each other. The attraction of the molecules forms hydrogen bonds with each other. This is called cohesion (attraction of similar molecules).  Due to this, water is able to create a surface tension that acts like a ‘skin’ and can support some weight (including its own weight) without collapsing.

Final answer:

The ability to fill a glass with water slightly above the rim without spilling is explained by water's cohesive property and surface tension, resulting from hydrogen bonding between water molecules.

Explanation:

The property of water that allows you to fill a glass to just slightly above the rim without it spilling over is known as cohesion. Cohesion is the result of water molecules being attracted to each other due to hydrogen bonding, which creates a strong intermolecular force. This attraction keeps the water molecules together at the liquid-gas (water-air) interface, forming a dome-like shape above the glass. This cohesive force gives rise to surface tension, which allows the water to hold together and not spill over immediately even when filled above the glass's rim.

Examples of cohesion and surface tension in action include floating a small scrap of paper or a steel needle on water. These objects can float because the surface tension at the water's surface can support their weight without the water breaking apart. Surface tension is the capacity of a liquid to withstand rupture when placed under tension or stress.

Answer:

15 km/h

Explanation:

The average speed of the bicyclist is calculated by dividing the total distance (30 kilometers) by the time taken (2 hours) which equates to 15 kilometers per hour. Therefore, the correct answer is (a) 15 km/h.

The subject of this question is Mathematics. Specifically, it's about speed calculation which is often seen in middle school math and physics curricula. The question is asking for the average speed of a bicyclist who travels 30 kilometers in two hours.

Average speed is calculated by dividing the total distance traveled by the total time it takes. In this case, the total distance is 30 kilometers and the time is 2 hours.

To find the average speed, we use the formula:

Average Speed = Total distance / Total time

Substituting the given values into the formula gives:

Average Speed = 30 km / 2 hours = 15 km/h

So, the correct answer is (a) 15 km/h. This is the average speed of the bicyclist over the two-hour period.
