What are 3 organisms that are found in the same phylum as euglena gracilis?

Natural selection may prevent worms from growing arbitrarily large because Darwin’s theory of natural selection had three essential ingredients: variation, inheritance, and selection.

Only those who survive and reproduce will give rise to new variation, and survival and reproduction are determined by interactions with the environment. Given differences in fitness, “sieving” will tend to be non-random.

Given “limitless” variation, prevailing or recurring circumstances can make for accumulation of useful structure. This dependence on environment is what makes for claims about the powers of natural selection (force). An important underlying assumption is that a particular structure is not equally close to any other structure from a developmental point of view.

A mutation yielding an individual of the trait type Tn might be more probable with a Tn-1-parent than with a Tn-2-parent.v So, if the environment is such that Tn-1 replaces Tn-2, this increases the probability of a mutation producing Tn.

The sugar molecule represents the most stored chemical energy. Thus, the correct answer is Option B.

Sugar (glucose, C₆H₁₂O₆) is a biological molecule that stores energy in its chemical bonds, not the molecule that initiates the process of cellular respiration During cellular respiration, glucose is broken down in a series of chemical reactions to produce energy ATP (adenosine triphosphate).

The process of cellular respiration begins at the stage of glycolysis, where glucose in the cytoplasm of the cell is partially broken down into pyruvate molecules and then the pyruvate molecules are broken down again in the presence or production of oxygen (aerobic respiration). fermentation in the absence of oxygen depending on whether oxygen is present

During aerobic respiration, pyruvate enters mitochondria and undergoes the citric acid cycle (also known as the Krebs cycle) and the electron transport chain These processes release energy from glucose chemical bonds to produce more ATP.

Therefore, sugar (glucose), although it stores energy in its chemical bonds, is not the molecule that initiates cellular respiration. Instead, during cell respiration, glucose is broken down and energy is released in the form of ATP.

By this criterion, Cuvier's explanation of the fossil record and Lamarck's idea of evolution are both scientific. Cuvier believed that species did not change throughout time.

Cuvier also proposed that extinctions in certain locations were triggered by rapid, catastrophic catastrophes, and that such areas were eventually repopulated by a new group of species that moved from other areas. These claims may be checked against the fossil record, and his claim that species do not evolve has been proven false. Lamarck's concept of use and disuse, for example, may be used to establish testable predictions for fossils of groups such as whale forebears as they adapted to a new home. Lamarck's notion of use and disuse, as well as his linked principle of the inheritance of experienced features, can be tested directly in live creatures; both have been proved to be erroneous.

Cellular respiration is a very important process for organisms because it is from it that part of the energy necessary for survival is generated.

In respiration, we consume oxygen and glucose and form carbon dioxide, energy, and water as products.

Therefore, we can say that the reactants of cellular respiration are oxygen and glucose. Therefore, option "D" is the answer.

The answers to the questions are as follows:

Question 1:

Response: B speciation

Question 2:

Response: A gene flow

Question 3:

Response: B speciation by geographic isolation

Geographic isolation plays a significant role in shaping the evolution of species. Let's address each question individually:

Question 1:

Geographic isolation may result in:

Response: B speciation

Geographic isolation refers to the physical separation of populations of organisms due to geographical barriers such as mountains, rivers, or islands. When populations become isolated from each other, they experience different environmental conditions and selective pressures. Over time, these distinct environments can lead to genetic and phenotypic differences between the isolated populations. This divergence in characteristics can eventually result in the formation of new species, a process known as speciation. Therefore, option B, speciation, is the correct response.

Question 2:

Geographic isolation causes a reduction in ____, eventually resulting in dissimilarities in a once-similar population of organisms.

Response: A gene flow

Geographic isolation restricts or limits the movement of individuals between different populations. This restriction reduces the gene flow, which is the transfer of genetic material between populations. Gene flow is an important mechanism for maintaining genetic diversity and homogeneity within a population. When gene flow is reduced, isolated populations experience different genetic changes and accumulate genetic variations independently. Over time, these genetic differences can lead to dissimilarities in once-similar populations.

Question 3:

Allopatric speciation is another name for:

Response: B speciation by geographic isolation.

Allopatric speciation refers to the process of speciation that occurs when populations are geographically isolated from each other. The term "allopatric" means "different homeland." In this form of speciation, the physical separation of populations by a geographical barrier prevents gene flow between them. As a result, the isolated populations undergo independent evolutionary changes, leading to the formation of new species. Therefore, option B, speciation by geographic isolation, is the correct response.

In summary, geographic isolation can lead to speciation (Question 1), it reduces gene flow (Question 2), and the process of speciation by geographic isolation is known as allopatric speciation (Question 3).

Answer:

Remove and lower.

Explanation:

Cells of the excretory tubule remove water by osmosis, from which we can conclude that the solute concentration in these cells must be lower than in the filtrate. The excretory tubule remove excess amount of water from the cell through semi permeable membrane of the cell while on the other hand, the solute concentration in the cell is lower as compared to filtrate so that's why it can't diffuse from the cell by the process of osmosis.

Hershey and Chase's work supported the findings of Avery's team by providing evidence for option D: "It showed that a virus's heritable information is also carried by DNA."

Hershey and Chase conducted an experiment using bacteriophages, which are viruses that infect bacteria. They labeled the DNA of the bacteriophages with radioactive isotopes and the protein coat with a non-radioactive substance. They then allowed the labeled bacteriophages to infect bacteria.

After infecting the bacteria, they used a blender to separate the protein coats of the bacteriophages from the bacteria. They observed that the radioactive DNA was transferred into the infected bacteria, while the non-radioactive protein coats remained outside. This experiment provided conclusive evidence that the heritable information of the bacteriophage, which determines its traits, is carried by DNA and not the protein coat.

This supported the earlier findings of Avery's team, who demonstrated that DNA is the substance responsible for carrying genetic information and passing it on to offspring. Hershey and Chase's work further solidified the understanding that DNA is the genetic material responsible for inheritance. Therefore, Option D is correct.

The mitochondrial DNA itself will vary between students because each of us inherited it from our moms; but since the same region is being amplified, the sequences of our PCR result will be the same.

Despite the fact that each student's mitochondrial DNA is unique because we all received it from our mothers, the sequences of our PCR results will be the same because the same region is being amplified. The fluid around the nucleus contains hundreds to thousands of mitochondria per cell (the cytoplasm).

The majority of DNA is stored on chromosomes in the nucleus, while mitochondria only store a little amount of their own DNA. This genetic material is referred to as "mtDNA," or mitochondrial DNA. In the human mitochondria, 16,500 DNA base pairs, or about 5% of the total, are present.

Answer:

Bacteriophage  

Explanation:

Bacteriophage is nothing but a virus that harms and kills the bacteria.

The Hershey-Chase Experiments is a well known experiment done by scientist, Alfred Hershey and Martha Chase. They conducted the experiment in the year 1952.

It was an extra ordinary experiment which made the world believe that the DNA is the genetic material and not a protein. In their experiment, they tried to find out if the protein coat or the core of the DNA of the virus which enters into the infected cells would help them to understand whether the genes were made of DNA or of protein.

They used sulfur-35 and phosphorus-32 radioactive isotopes to trace the DNA and the proteins.

Answer:

Explanation:

Hershey and Chase started with a virus called a bacteriophage.

They used the radioactive isotope sulfur-35 to label the protein

of the virus and phosphorus-32 to label the DNA of the virus.

They allowed the tagged virus to infect bacteria and studied the results. Hershey and Chase found that the only radioactive isotope within the bacteria was 32P.

This result indicated that the genetic material inserted by the virus to infect the bacteria was DNA.
