Answer:
True
Explanation:
Doppler's effect is the apparent change in the wavelength and frequency of a wave as it moves towards or away from an observer.
The relative motion between the observer and the source causes changes to the wavelength and frequency. This effect is the doppler's effect. When a source moves closer, the frequency of the wave increases. For example, we see that effect of water ripples when a stone is dropped in still water.Place the next two tRNA molecules on the mRNA strand. What happens?
Answer:
Required Answer:-The tRNA left the ribosome. The amino acids stayed and the mRNA partially left the ribosome.If place the next two tRNA molecules on the mRNA strand, the amino acids shifted to the next tRNA molecule.
How are tRNA molecules involved during protein synthesis?
tRNA departed from the ribosome, while the mRNA partially exited the ribosome, the amino acids remained. While a tRNA molecule separates from the mRNA and leaves the ribosome, the neighboring amino acids join with one another.
The ribosome adds the amino acid carried by each tRNA molecule to the lengthening amino acid chain as it attaches to the mRNA.
The polypeptide chain is once more transferred to the new tRNA, the empty tRNA is released, and the ribosome ratchets through the mRNA by three further nucleotides while also shifting the tRNA.
Therefore, the ribosome and the mRNA are drawn to a tRNA whose anticodon is complementary to the next codon in the mRNA.

A vacuoles function is somewhat similar to the function of human Kidney.
What are vacuoles?
A vacuole is a cell organelle found in animal, plant, bacteria, protist, and fungi cells. It’s one of the largest organelles found in cells, resembles a large sac surrounded by a thin membrane called tonoplast filled with fluid.
The main function vacuoles serves as the storage unit of the cell by holding various substances and molecules.
The contractile vacuoles of protozoans and freshwater sponges are especially evolved to serve the function of expelling out excess of water and salt. It is thus, work similar to human kidneys as an organ of osmoregulation and excretion.

One similarity between DNA and mRNA is that they both ..... pls help !!!
Answer:
B) Both contain genetic codes based on sequences of bases
Explanation:
DNA chemical bases are ATGC, while mRNA chemical bases are AUGC. Uracil replaces Thymine in mRNA, so your answer (option C) is incorrect. However, they are similar in that mRNA carries genetic code from DNA in a cell's nucleus to ribosomes, while DNA contains the genetic information for development and function of living things.

volcanic eruptions can affect climate by
Answer:
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
Hope this helped, have a good day
Answer:
Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. Injected ash falls rapidly from the stratosphere -- most of it is removed within several days to weeks -- and has little impact on climate change

In which situation might a gene pool contain an allele that causes a lethal
disease?
A. If the allele is in the mitochondria
B. If the allele is expressed after reproduction has occurred
C. If the allele is on the Y chromosome
D. If the allele is expressed in its dominant form
correct answer is B; if the allele is expressed after reproduction has occurred.
The situation in which a gene pool contain an allele that causes a lethal disease is: (B) If the allele is expressed after reproduction has occurred.
When the allele is expressed after reproduction has occurred, individuals carrying the lethal allele can reproduce and pass on the allele before the disease is expressed. Since the disease may not manifest until later in life or after reproduction has occurred, the allele can persist in the gene pool without being selected against. Over generations, the allele frequency can remain relatively stable, leading to the presence of the lethal allele in the gene pool.
An allele can be defined as a variant form of gene. Alleles can exist in different forms due to changes in the DNA sequence. These changes can be substitutions, deletions, insertions, or other types of genetic mutations.

Why can a planet orbit circular?
Answer:
Explanation:A circle is merely a special case of an ellipse. However, the planets do not quite move in ellipses either. The increased kinetic energy of a planet as its distance from the Sun decreases causes it to behave as though it had a greater mass, which results in the point of the orbit furthest from the Sun precessing.

If bugs did disperse what are the costs and benefits of accepting a host plant of either species?
Answer:
How could a dispersing bug know what species of plants it would be settling on? A bug can know what bug it is landing on by sight, smell and taste. All insects disperse, even those without wings, so the question contains a false assumption and is therefore unanswerable. In general, the contribution of any particular trait to an organism's fitness depends on the details of the life cycle. Without knowing those details, it's impossible to say.
But for benefits, there are a lot of benefits of accepting a host plant. Some of the benefits are:
It is an avenue or a strategy for egg laying females when larvae must feed on plant so as to complete development bugs or insects are attracted to flowers due to its scent or brightly coloured petals. These flowers produce a sweet liquid, called nectar, which the bugs or insects feed on.Learn more from
