Critique the phrase airspeed velocity of a swallow as Its redundant. The velocity of a flying object already includes its airspeed.

It's obvious, you'll be thinking of African or European swallow; we might consider the West African swallow, or the South African Cave swallow, however, choosing one between these two would be completely arbitrary- and neither is it sufficiently studied to provide the absolute data we need.

Not withstanding, there is an accepted way to estimate the airspeed of a bird using Strouhal ratio's equation. This states that "the frequency of wingbeats multiplied by their amplitude and divided by the airspeed of the bird provides a semi-constant value." This is known as the Strouhal number and averages between 0.2 and 0.4 for most birds, with a higher number denoting a less efficient flight pattern.

Flight is (for those poor people who we're not opportune to watch it) clearly very efficient, seeming almost effortless. So we’ll go for the lower end of Strouhal numbers in our working, giving us (drumroll please), an airspeed velocity of 11–16 metres per second. That’s 40–60 kilometers per hour.

Therefore, Critique the phrase airspeed velocity of a swallow as Its redundant. The velocity of a flying object already includes its airspeed.

The answer to your question are the Somatic cells. They are all of the cells that are not related to reproduction. Hope this helped!

Answer: Somatic cell

Explanation:

A somatic cell is any cell forming the body of an organism that is not a gamete, germ cells or undifferentiated stem cell. For example, skin cell, muscle cell, blood cell and others. Thereby, they are all cells that make up an organism and are not used to form a new organism during reproduction. New somatic cells are created through mitosis, when a cell divides to form two identical diploid cells. The major purpose of this type of cell division is for growth and to replace cells.

Germ cell give rise to the gametes, which are reproductive cells (egg or sperm). They are haploid cells because they carry only one copy of each chromosome. They create new gamete cells through meiosis. And undifferentiated stem cells can divide to produce other cells that continue as stem cells or cells that are destined to differentiate.

B) small non-polar molecules. Small molecules can pass through the cell membrane through diffusion (does not require energy). The molecule being non-polar is an advantage because the tails of the phospholipid bilayer is hydrophobic (nonpolar), so it does not repel nonpolar molecules.

Small nonpolar molecules, due to their compatibility with the nonpolar interior of the cell membrane, will pass through a cell membrane most easily.

As per the properties of the cell membrane, small nonpolar molecules will pass through a cell membrane most easily. This is because the cell membrane is a lipid bilayer, in which the main components are phospholipids. These phospholipids are made up of a polar 'head' and two nonpolar 'tails'. Hence, the nonpolar (hydrophobic) interior of the cell membrane allows nonpolar molecules like oxygen and carbon dioxide to easily cross the membrane without requiring any additional energy, hence making choice B) the answer to your question.

Answer

The following steps can be taken to prevent rickets;

• Maintaining a healthy diet with good source of vitamin D

• Taking vitamin D supplement

• Basking on the sun

Explanation

Rickets  is a condition characterized by softening and weakening of bones in kids due to lack of vitamin D. Vitamin D is essential in the body because it helps in absorption of calcium and phosphorus. When a kid lacks vitamin D, he or she faces challenges of maintaining enough levels of calcium and phosphorus in the bones resulting to rickets.

Answer:

Point source pollution and nonpoint source pollution are both potentially harmful to the environment. The main difference between point source pollution and nonpoint source pollution is that point source pollution is easier to track to its source. The source of pollution is easily identifiable in point source pollution, but not in nonpoint source pollution. For this reason, point source pollution is easier to regulate and therefore easier to control. This makes nonpoint source pollution potentially more harmful to the environment.

By dating the age of intrusions and extrusions near a sedimentary rock layer.

Sedimentary rocks are one of three main types of rocks, along with igneous and metamorphic. They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes.

In contrast to metamorphic and igneous rocks, which are generated deep beneath the Earth, sedimentary rocks are formed on or around the surface of the planet.

The impacts of wind and rain, which gradually reduce huge boulders into smaller ones, are included in erosion and weathering. Boulders and even mountains become sediments, such as sand or mud, as a result of erosion and weathering.

The force of gravity is a major force that created the earth.  As rocks and ice clumped together as they spun around the newly formed star (sun), the force of gravitational pull increased and attracted more debris (rocks and ice). The clumps of rocks, debris, and ice, therefore, grew into a planet.  

Another is electromagnetic force. The spinning currents in the outer core of the earth create a dynamo effect that forms a magnetic field around the earth. This shields the earth from the solar storms of the sun hence protects life and the atmosphere.

Weak nuclear force is responsible for maintaining the heat of the earth’s interior which is critical for maintaining the dynamo  effect of the outer core so the earth is protected by its magnetic field.

The scientist would likely suggest that the decrease in frog population may have both positive and negative impacts on various bird populations, based on their individual adaptability and alternate food sources.

The most likely response from the scientist studying the ecosystem and decreasing population of frogs would be option C: 'Loss of frogs is likely to have positive effects on some bird species and negative effects on others.' This is because every species in an ecosystem is interconnected. Frogs are a food source for certain bird species, and their loss could lead to declines in those bird populations. However, some other bird species might benefit if they can easily switch to other food sources, such as insects or small mammals, that might become more abundant in the absence of frogs.

Answer:

A) They release radioactive waste.

Explanation:

Fossil fuels are non renewable resources  do not release radioactive wastes / materials, but they do release greenhouse gases, causing air pollution.

Final answer:

The statement not associated with the drawback of using fossil fuels is that they release radioactive waste. Fossil fuels cause air pollution and release greenhouse gases and are non-renewable, but do not create radioactive waste. Thus, option A is correct.

Explanation:

The question asks to identify which statement is not a drawback of using fossil fuels. The correct answer is A. They release radioactive waste. This is a drawback associated with nuclear power, not fossil fuels. However, fossil fuels are known to cause significant air pollution, emit greenhouse gases, and are non-renewable resources.

Fossil fuels, such as coal, oil, and natural gas, take millions of years to form and hence are classified as non-renewable. The combustion of these fuels releases large quantities of carbon dioxide (CO2), which is a greenhouse gas that contributes to global warming. Additionally, the burning of fossil fuels results in the release of pollutants into the air, contributing to air pollution.

Answer is A. Ribosome  

Ribosome cell structure does a bacterial cell lack.

A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell.

The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.

The biological machinery that produces proteins is known as a ribosome. Each cell contains several ribosomes, which are each composed of two subunits. These two subunits form a tight seal around the messenger RNA molecule before moving down its length and reading each three-letter codon.

Therefore, Ribosome cell structure does a bacterial cell lack.

Answer:

C)frame-shift

Explanation:

Since the protein-encoding DNA is divided into codons of three bases each, insertions and deletions can alter a gene to the point that its message loses its meaning. These changes are called the reading frame offset.

For example, consider the phrase: "The fat cat sat". Each letter represents a codon. If we delete the first letter and try to analyze the sentence in the same way, it doesn't make sense. In frame-shift, a similar error occurs at the molecular level, causing the codons to be analyzed incorrectly. This usually produces useless proteins.

11. B (have anti-codons which correspond to the codons on the mRNA)

16. True (proteins get their function mostly from their shape. If they are denatured/bent out of shape, they are no longer functional)

Answer:

The correct answer option is: frequency of the recessive allele.

Explanation:

When there are no mutations, no selective forces, no gene flow, no non-random mating and large population size, the population is said to be in Hardy- Weinberg equilibrium.

When Hardy-Weinberg equilibrium is met, it is written in the form of an equation which is as follows:

[tex]p^2+2pq+q^2=1[/tex]

where [tex]p^2[/tex] represents the frequency of the homozygous dominant allele, [tex]2pq[/tex] is the frequency of the heterozygous  allele while q or[tex]q^2[/tex] represents the frequency of the homozygous recessive allele.
