Answer: C) the genes of this phage were made of DNA.
Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.
What will most likely increase if there is a high death rate? immigration emigration birth rate population
Answer:
Emigration
Explanation:
If there is a large number of deaths, then the population would move onto another area to find a mate, more food, and to be together to protect themselves from danger
The component of population that will most likely increase with a high death rate would be emigration.
When the death rate shoots up in a particular environment due to certain factors, organisms are bound to emigrate away from such environment to avoid death from reaching them.
It is a natural instinct of every living organism to respond to stimuli. A high death rate is a stimulus that organisms would want to move away from.

Asthma is a respiratory disorder that can cause the airways to temporarily constrict, or get narrower. Which function of the respiratory system is most affected by the narrowing of the airways? A. water balance B. air filtration C. heat balance D. gas exchange
Answer:
Answer is D.
Explanation:
Asthma is a chronic inflammation that affects the airways, directly affecting the gas exchange of oxygen and carbon dioxide with the blood.
What is asthma?It is a chronic disease of the lungs that inflames and narrows the airways.
Since this disease causes the airways to become inflamed and swollen, it reduces the amount of air that can move in and out of the lungs (gas exchange).
Therefore, we can conclude that asthma is a chronic inflammation that affects the airways, directly affecting the gas exchange of oxygen and carbon dioxide with the blood.

(Applicable answer gets brainliest) community is located in the desert, near an area with high winds. There is very little rainfall or clouds and no large rivers nearby. The people want to build a power plant that will not pollute. They are choosing among solar, biomass, or hydroelectric power. Write one to two sentences about each of these energy sources. Describe whether each energy source would meet their goals and whether it is a good energy source for their area.
Answer:
In the given scenario, solar power would be the best and the most effective kind of power plant to be constructed in the mentioned location. This is because the generation of pollution by using solar power is negligible. Apart from this, the use of solar power plants would be the most ideal in the given community resources as the community is receiving ample amount of sunlight and the presence of less cloud cover makes the application of solar power more feasible.
If one considers biomass, then there would be the requirements of the things like crops, wood, alcohol fuels for burning so that energy can be generated, and with more than the required amount of sunlight and less or no irrigation, sources would make it hard to obtain the sources necessary for biomass power plant.
The hydroelectric energy would not even be a viable option in the given scenario as the community has no accessibility of natural water sources and the hydroelectric power concept primarily works on water storage.

A student draws this model to show how humans evolved from ancestral primates. What are the pros and cons of
this model in regard to the theory of evolution? Explain how you'd make it more accurate. To create a scientifically
credible answer, use a credible website to research human evolution.
Answer and explanation:
The model designed by the student is useful to explain in a simple way the question of the evolution of the homo gender (our gender), mainly in basic education, but it may seem inconsistent at higher educational levels.
Humans and chimpanzees, according to the theory of evolution, descend from a relatively recent (about 7 million years) common ancestor.
These same species, as well as lemurs, baboons and all other primate species, share an ancestor who lived longer. Likewise, there is an even older ancestor that originated primates, bats, whales and all other groups of mammals .
The fact that chimpanzees have a DNA very similar to ours (about 98.5% similarity between code sequences) is because the successive evolutions from this common ancestor were not very drastic, besides the fact that they are in a branch more close to ours from the moment of separation of evolutionary lineages.

Which is the correct sequence of events when the RER delivers transport vesicles to the Golgi apparatus? 1 – Small vesicles move material from one cisterna to the next. 2 – Enzymatic modification occurs. 3 – Arrival at the trans face. 4 – Arrival at a cisterna known as the cis face."
Answer:
The correct order of events when RER delivers transport vessicles to the Golgi apparatus are;
4,2,1,3
Arrival at a cisterna known as the cis face."
Enzymatic modification occurs.
Small vesicles move material from one cisterna to the next.
Arrival at the trans face.
Explanation:
Rough endoplasmic recticulum are flat sacs in the cytoplasm that help in the synthesis of protein. It vesicle or sac floats through the cytoplasm to the Golgi apparatus and is absorbed. The Golgi apparatus is an organelles in the cytoplasm that help to package protein into membrane bound organelle in the vessicles.
The vessicles that bud off join to the rough endoplasmic recticulum, Molecules travel through the Golgi apparatus through the vesicle transport till they get to the end of the assembly line at the biggest sacs from endoplasmic recticulum called the trans-Golgi.
Firstly, the particles arrive at cisterna known s Cis face. The cis face is the end of the organelle where substances enter from the endoplasmic reticulum for processing into the Golgi apparatus.
Then there is enzymatic modifications which is done by the activities of enzymes.
Small vessicles then Transport material from the cisterna.
It is then transported to the trans face. The trans face is where the particles leave in the form of smaller detached vesicles.

Drag each label to the correct location. Identify the cell organelles found only in plant cells and those found in both animal and plant cells. nucleus cell wall chloroplast Golgi apparatus cell membrane ribosome
Answer:
Plant cell: chloroplast, cell wall
animal and plant cells: nucleus, cell membrane, ribosome, golgi apparatus
Explanation:
The organelles that are specific to the plant cell only among the listed organelles include chloroplast and cell wall, while those found in both animal and plant cells include the nucleus, cell membrane, ribosome, and golgi apparatus.
The chloroplast contains the green pigment (the chlorophyll) that is present in all green plants. It is the organelle that confers greenness to plants and is therefore absent in animal cells. The rigid cell wall is only found in plant cells and this confers a kind of hexagonal shape to the cell, unlike the animal cell that lacks a rigid cell wall and therefore, shapeless.
All eukaryotic cells, including plant and animal cells, posses nucleus. It is an organelle that houses the genetic materials of the cell and acts as the control center of the cell. The cell membrane is also common to both cell and acts as a selectively permeable membrane to the cells. The ribosome is the organelle responsible for protein synthesis in both plant and animal cells while the golgi apparatus plays an important role in secretory pathway in both cells.
Answer:
Explanation:
A sexually reproducing animal has two unlinked genes (on separate chromosomes), one for head shape (H) and one for tail length (T). Its genotype is HhTt. Which of the following genotypes is possible in a gamete from this organism assuming no errors in meiosis?
a) HT
b) Hh
c) HhTt
d) T
e) tt
Answer:
a) HT
Explanation:
This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.
According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.
Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.
Therefore, HT is the genotype possible in a gamete of parent: HhTt.

How do the frequencies of the waves compare?
O Wave A has a lower frequency because it has a
smaller amplitude.
O Wave A has a higher frequency because it has a
shorter wavelength.
The waves have the same frequency because they
have the same wavelength.
O The waves have the same frequency because they
have the same amplitude.
Answer:
O. Wave A has a higher frequency because it has a shorter wavelength.
Explanation:
Wavelength refers to the distance between two crests while frequency refers to the number of waves passes through a specific point per second. Frequency and wavelength are inversely proportional to each other. Inversely proportional means if one increases, the other decreases and vice versa. If the frequency of the wave is higher so its wavelength becomes shorter and if the frequency of the wave is shorter so its wavelength is higher.
Answer: B.
Explanation: Wave A has a lower frequency because it has a longer wavelength.

What could we reasonably conclude about C5M treatment efficacy across all cervical cancer cell lines, using this new information and the data within the passage
Answer:
The division of cervical cancer cells will be inhibited
Explanation:
Aurora kinases are a type of serine/threonine kinase enzymes that play critical functions during cell proliferation, and they are recognized to be potential targets in cancer therapy. The benzo[e]pyridoindole (C5M) agent is a hydrosoluble inhibitor of aurora kinases capable of inhibiting cell proliferation. C5M induces mitotic arrest by faulty (no separation) of the sister chromatids during cell division, thereby eventually leading to polyploidy and finally triggering cell death. It has been shown that C5M acts to prevent the entry in mitosis by inhibiting histone 3 (H3) phosphorylation of aurora kinases.

Environmental variation has a big role for their beaks to change in a size and shape , that means if the birds like the condition of the place specially birds like to eat cactus fruits that is the reason for their beak rapid change
Which of the following mutations is NOT a point mutation? A. Silent mutation B. Nonsense mutation C. Missense mutation D. Insertion mutation
the answer is Insertion mutation :)
(search up "types of mutations")
Point mutation is the alteration of the single nucleotide base in the sequence. Insertion mutation is not a type of point mutation. Thus, option D is correct.
What is point mutation?A point mutation is a modification and change in the base of the genetic sequence. In this type of mutation, only a single nucleotide base is altered. Point mutations are categorized as transition mutations and transversion mutations.
Silent, Nonsense, and missense are the transversion type of point mutation. In this mutation, the purines get altered by pyrimidines and vice versa. On the other hand, insertion mutation is the frameshift mutation.
Therefore, insertion is not a type of point mutation.
