Answer:

egg, sperm, zygote

Explanation:

The female reproductive cell is an egg, or, more scientifically, an ovum.

The male reproductive cell is a sperm.

The male and female sex cells combine in a process called fertilization to form a zygote that eventually grows and develops into an offspring.

The water flea will compete with native species for food, leading to a decrease in organisms that are important to other species. The Correct option is B

The introduction of spiny water fleas to the lake poses a significant ecological concern. Since they consume zooplankton, which is also a vital food source for native fishes, competition for this shared resource is inevitable. The water fleas will compete with native species for the available zooplankton, resulting in a decrease in the abundance of these organisms.

This can disrupt the food web dynamics and have adverse effects on the population of native fishes and other species that rely on zooplankton as a crucial part of their diet. The spiny water flea's spread through human activities enhances their invasion of new lakes, exacerbating the competition and potential negative impacts. The Correct option is B

C4 plant separates initial co2 fixation and the Calvin cycle by time.

In conditions with high levels of heat, aridity, and light, CAM metabolism in plants developed. This approach's main objective is water conservation. Recall the trade-off between respiration and photosynthesis. (paradox). Making compromises is unaffordable for plants in arid conditions since doing so results in significant water loss through open stomata during the day. By opening the stomates at night to take in carbon dioxide, CAM plants found a solution to this issue. This tactic is just "regular" plants turned around. The byproducts of light-dependent reactions like ATP and NADPH, on the other hand, are no longer accessible because carbon dioxide has been fixed. The solution to this issue was to overnight store the carbon dioxide until the following day when ATP and NADPH were available.

The frequency of this wave is 5 waves per second, or 5 hertz (Hz).

This refers to the number of waves passing a point in a second. The unit of frequency is measured in hertz (Hz). One hertz is equal to one wave per second.

To calculate the wavelength and speed of a wave, these can be used to find the frequency of a wave:

f = v λ

where

λ  = the wavelength in meters

v = the speed of the wave in m/s.

This also gives the frequency of the wave in Hertz.

From the question:

f = 5

Hence, If 5 waves passes through a certain point in 1 second the frequency of this wave is 5 hertz (Hz).

Explanation:

The stratosphere is the one of the four layers of the atmosphere are defined by temperature inversions.

The stratosphere is distinguished by a significant temperature inversion. The stratosphere differs from the remaining three layers of air, that include the lower atmosphere, mesosphere, and thermosphere. In contrast to the lower atmosphere, where temperatures decline with height, temperatures increase with altitude in the stratosphere.

This temperature shift is due to the presence of ozone within the stratosphere, that absorbs UV energy from the sun and generates heat. As a result, the stratosphere is a consistent layer that protects life on Earth first from sun's deadly radiation. Pollutants as well as other particles may so remain in the stratosphere for so many years.

Answer:

Look down!! ;)

Explanation:

So, as the number of water vapor molecules increases in the air above the water, the condensation rate increases, too. The condensation rate will continue to increase until it matches the evaporation rate, which is a state called equilibrium, meaning the condensation rate equals the evaporation rate.

The use of a refractometer over a urinometer is preferred due to the fact that the refractometer uses a small volume of urine and compensates for temperature. Option C.

The use of a refractometer over a urinometer is preferred because the refractometer uses a small volume of urine and compensates for temperature.

A refractometer is an instrument that measures the refractive index of a substance, which is the extent to which light is bent as it passes through the substance. The refractive index of urine is related to its concentration, and therefore, the refractometer can be used to measure the specific gravity of urine.

A urinometer, on the other hand, is a device that measures the density of urine by floating in a sample. It requires a larger volume of urine and does not compensate for temperature.

Since the refractometer requires only a small volume of urine and compensates for temperature, it is a more convenient and accurate tool for measuring the specific gravity of urine. It is commonly used in clinical settings to assess kidney function and hydration status.

High antigenic variation through increased mutation rates. The biological property of a pathogen that could block the successful design of an effective vaccine is having a high antigenic variation through increased mutation rates.

Antigenic variation is a biological property of pathogens that involves changes in their antigenic structure, and it could block the successful design of an effective vaccine. Increased mutation rates cause the emergence of new antigenic variants that are different from previously existing ones. This makes it challenging to design a vaccine that targets all the existing antigenic variants, particularly if they are continually emerging or evolving. This means that even if an effective vaccine is intended for a particular variant, it may not be effective against other variants, limiting its efficacy.

Antigenic variation is common in RNA viruses like influenza viruses, human immunodeficiency virus (HIV), and coronaviruses like SARS-CoV-2, which causes COVID-19. The influenza virus has a high mutation rate, which explains why people need to get vaccinated annually because the vaccine efficacy reduces due to the emergence of new strains. HIV also undergoes antigenic variation, which makes it challenging to design a vaccine that targets all existing strains.

In conclusion, the high antigenic variation through increased mutation rates is a biological property of pathogens that could block the successful design of an effective vaccine.

Answer:A-Allele

Explanation:

just took the quiz

The alternate form of gene that nucleic acids have that allows them to offer variability is the allele that is present in the first option, and there are more than two alleles present for one gene.

The gene is the message that is present in the DNA, and the gene of the prokaryotes contains very few introns, while the gene of the eukaryotes contains many introns, and the genes only express their exon parts, not the introns. In most cases, the gene has two alleles, and depending on the alleles' presence on the homologous chromosomes, the character is expressed. Some genes that have more than two alleles are called multiallelic genes, and they show the combined effects of their alleles.

Hence, the alternate form of gene that nucleic acids have that allows them to offer variability is the allele that is present in the first option.

Answer:

Electrical energy is defined as the energy flowing through a device due to the flow of electrons or charges from one point to another.

The energy present within an object or material due to the sum of its motion and potential energy is known as mechanical energy.

Thermal energy is defined as the energy present within an object because of the motion of its particles.

So, when we plug in and turn on a hair dryer then electrical energy starts to flow. As a result, some of its molecules will gain kinetic energy and some will have potential energy.

Hence, its sum will lead to formation of a mechanical energy. Since, this mechanical energy gets converted into thermal energy due to which hairs get dry.

Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.

Stony corals are the most important reef builders, but organ pipe corals, precious red corals, and blue corals also have stony skeletons.

There are also corals that use more flexible matter or tiny stiff rods to construct their skeletons—the sea fans and sea rods, the buoyant soft corals, and the black corals. Coral reefs protect the seaboard from storms and erosion, provide jobs for local groups, and offer opportunities for pleasure. They became the planet's very first reef-builders and are index fossils for take-out Lower Cambrian rocks worldwide.

Coral reefs are built by coral polyps as they produce layers of calcium carbonate below their bodies. The corals that build reefs are known as “hard” or “reef-building” corals.
