Answer:

No

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

Answer:

A. Resource availability sets the limit.

Explanation:

The availability of resources actually affects the carrying capacity by setting a limit to it.   The carrying capacity of an environment is known to be the maximum population size which can be sustained in that environment by the given resources like food, water, habitat, and others. Such availability of resources will determine the limit of the population in that environment. This then means that if the carrying capacity exceeds the available resources it will result to an adverse effect on the environment.

The gizzard is the muscular organ located between the crop and the small intestine in birds. Its primary function is to mechanically grind and break down food, as birds do not have teeth to chew their food.

The gizzard accomplishes this through strong muscular contractions that crush and grind the food against small stones and grit that the bird has ingested.

Therefore, it is likely that the contents found in the gizzard would be more ground up compared to those found in the crop. The crop is a storage organ located at the base of the bird's neck that serves as a temporary holding place for food before it enters the digestive system. While the crop may soften and partially break down food through the secretion of digestive enzymes, it does not have the same mechanical grinding function as the gizzard.

In summary, the gizzard is the organ responsible for grinding and breaking down food in birds, while the crop primarily serves as a temporary storage organ. Therefore, the contents found in the gizzard are likely to be more ground up compared to those found in the crop.

Answer:

If the GENES of the parental mice encodes for a black fur, THEN the FUR COLOR of one of the offspring mice will be black.

Explanation:

Hypothesis is one of the steps used in the scientific method. It is a testable explanation of a given question or observation. Hypothesis in an experiment must be subjected to testing via experimentation in order to determine whether to reject it or not.

Hypothesis is usually constructed in the IF, THEN format. It tells us how the independent variable (cause) affects the dependent variable (outcome). In this case, a question is asked this: "what is the effect of the genes of the parental mice on the fur color of the offspring mice?"

A possible hypothesis will be: If the GENES of the parental mice encodes a black fur, THEN the FUR COLOR of one of the offspring mice will be black.

Answer:

A. If either parent mouse passes a dominant allele, the offspring will have black fur.

Answer: D

Explanation:

Carbohydrates and nucleic acids are the two main classes of biomolecules which are involved directly in the process of digestion of maltose through maltase enzyme. Thus, the correct option is D.

Maltase is a an enzyme which belongs to the alpha-glucosidase enzyme family. These are found in the small intestine's brush bordered cells. The hydrolysis of the disaccharide maltose into two simple sugars such as glucose is catalyzed through the enzyme maltase.

Maltose is a disaccharide which is produced by the enzymatic hydrolysis of starch, which is a homopolysaccharide and this is catalyzed by the enzyme amylase. Maltose sugar is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.

Therefore, the correct option is D.

Answer:

In genetics, a trait is considered dominant when it is expressed in the phenotype of a heterozygous individual, meaning that it only requires one copy of the dominant allele to be expressed. On the other hand, a recessive trait is only expressed when both copies of the allele are present in the individual's genotype.

To provide the best evidence that a trait is dominant, we would need to observe the trait in the phenotype of all individuals who carry at least one copy of the dominant allele. This means that if an individual has one dominant allele and one recessive allele, they should still show the dominant trait in their phenotype.

In practice, this could be demonstrated through a series of crosses between individuals with known genotypes. If the offspring of a cross between a homozygous dominant individual and a heterozygous individual all show the dominant trait, this would be strong evidence that the trait is dominant. Similarly, if the offspring of a cross between two heterozygous individuals show the dominant trait in a 3:1 ratio, this would also support the idea that the trait is dominant.

In general, the best evidence for a dominant trait would be consistent expression of the trait in the phenotype of individuals who carry at least one copy of the dominant allele. This can be observed through controlled breeding experiments and statistical analysis of the resulting offspring.

The fact that introduced species can result in biological exponential multiplication does not mean that they are a threat to biodiversity.

Biodiversity is defined as the variety of all living things, including various plants, animals, and microorganisms. It is often investigated at three levels: genetic diversity, species diversity, and ecological diversity. We cannot have healthy ecosystems, which we rely on to provide the air we breathe and the food we consume, without a variety of animals, plants, and bacteria. One reason why introduced species are a hazard to biodiversity is that they have the potential to become invasive species that supplant native species and prey on native species, causing unnatural reductions in native species populations. Even if imported species have the potential to multiply biologically exponentially, this does not necessarily entail that they endanger biodiversity.

Answer:

Passive transport .

Explanation:

Passive transport is a kind of transport which is used by Paramecium to remove excess water from its cytoplasm. There is a inverse relationship between the contractile vacuole activity and the environmental salt concentration because if there is salty environment, the contractile vacuole did not their function because there is difference in pressure and the water moves outside when there is salty environment. Bursting of paramecium occur if a biological toxin blocked the activity of the contractile vacuole because no excess water moves to outside environment.

An increase of ADH causes the kidneys to Increase the reabsorption of water , causing them to produce less urine.

The brain secretes antidiuretic hormone (ADH), which causes the kidneys to release less water and lowers the volume of urine produced. When ADH levels are high, the body produces less urine. When the level is low, more urine is generated.

ADH levels are often greater during nighttime in the body. This helps prevent you from passing out while you're sleeping. However, if ADH levels remain low throughout the night, the body will generate significant volumes of urine, making nighttime urination more likely.

When this hormone system in children grows slowly, it might stop ADH from rising naturally at night. This may make nighttime bedwetting more likely. This issue often resolves itself over time.

1. The energy of the wave is quadrupled if the amplitude is doubled.

2. The frequency of a wave is not directly related to its energy.

1. When the amplitude of a wave is doubled, the energy of the wave increases. The amplitude of a wave represents the maximum displacement of particles in the medium from their equilibrium position. As the amplitude increases, the particles oscillate with greater displacement, resulting in more energy being transferred through the wave.

The energy of a wave is directly proportional to the square of its amplitude. This means that if the amplitude is doubled, the energy of the wave will be quadrupled (increased by a factor of four). This relationship holds true for various types of waves, including mechanical waves like sound waves and electromagnetic waves like light waves. Therefore, doubling the amplitude of a wave leads to a significant increase in its energy content.

2. The frequency of a wave is not directly related to its energy. The frequency of a wave refers to the number of complete oscillations or cycles it undergoes per unit of time. On the other hand, the energy of a wave is determined by its amplitude, which represents the magnitude or intensity of the wave.

While frequency and energy are independent properties of a wave, they can indirectly affect each other. For example, in certain wave phenomena, such as the photoelectric effect, higher frequencies of electromagnetic waves (e.g., light) are associated with higher energy photons. However, this relationship is specific to certain interactions and is not a general rule that applies to all types of waves.

In summary, the frequency of a wave and its energy are distinct properties. The energy of a wave is primarily determined by its amplitude, while frequency relates to the number of oscillations per unit of time.

Answer: it is b

Explanation:

The two methods that allow fish to maintain water balance in saltwater are pumping out salt through the gills and absorbing water into the body by osmosis.

In saltwater, the concentration of dissolved salts is higher in the surrounding water than in the fish's body cells. To maintain water balance, fish have developed two main methods:

1. Pumping out salt through the gills: Fish possess specialized cells in their gills that actively pump out excess salts from their bodies. This process helps maintain a lower salt concentration within the fish's body, preventing dehydration and maintaining water balance.

2. Absorbing water into the body by osmosis: Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. Fish have a protective layer of skin that allows water to be absorbed into their bodies while preventing the entry of excessive salts.

By absorbing water through their skin, fish replenish the water lost to the surrounding saltwater, helping to maintain their internal water balance.

These two mechanisms work together to enable fish to survive in saltwater environments. By actively pumping out salts and absorbing water, fish can regulate their internal salt concentration and prevent dehydration, ensuring their overall water balance is maintained.
