What are the seven 7 levels of
classification?

Answer:

lower

Explanation:

Enzymes are chemical substances or biological molecules that catalyze biological reactions by lowering the activation energy threshold required to start such reactions.

The activation refers to the minimum energy that must be conquered by the reactants in a chemical reaction in order to cross over to the product's side.

Enzymes work by lowering this energy and hence, making the crossing over to the product's side faster than normal. They are not themselves used up in reactions and can always be recovered and reused.

Correct answer: lower

Explanation:

The vertebrate forelimb of human, bird, and bat may not appear to have much in common, but a closer examination of the anatomy shows that the same bones were applied to a variety of different jobs in each of these species. Evolution doesn't plan ahead. It can only work with what's available. The color coding shows the way the bony elements were modified in each species. You might think that the two wings would be more similar in design because of the job they do but, in fact, the bird wing and human arm are more similar on the interior. However, the bird "hand" is reduced, whereas the bat and human hand have more in common. See if you can find a similar image of a dolphin or whale flipper for another comparison

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Natural selection is one of the ways to account for the millions of species that have lived on Earth.

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure 9.3.3 shows the upper appendages of several different mammals. They all have the same basic pattern of bones, although they now have different functions. All of these mammals inherited this basic bone pattern from a common ancestor.

The statement best describing a reliable source of information is:A source that follows the scientific method.

A reliable source of information is one that follows the scientific method. The scientific method is a systematic approach to investigating phenomena, which involves formulating a hypothesis, conducting experiments or observations, collecting data, and drawing conclusions based on evidence. By adhering to the scientific method, a source ensures that its information is based on rigorous and objective analysis.

A reliable source of information focuses on providing evidence to support its claims rather than relying on opinions. It presents data, facts, and research findings obtained through scientific studies or credible sources. This evidence-based approach adds credibility to the information presented and allows readers to evaluate the validity of the claims.

On the other hand, a source that includes opinions to support a claim may lack objectivity and can introduce bias into the information. Opinions alone do not necessarily provide a reliable basis for making informed judgments or decisions.

A reliable source also avoids the use of pseudoscience to gather evidence. Pseudoscience refers to claims or practices that are presented as scientific but lack the rigorous scientific methods and evidence required for validation. Such sources often promote ideas that are not supported by credible scientific research and can mislead readers.

In summary, a reliable source of information is one that follows the scientific method, presents evidence to support claims, avoids relying solely on opinions, and does not use pseudoscience to gather evidence. By adhering to these principles, a source can provide trustworthy and accurate information to its audience.

We could conceive Muller´s Ratchet, as the following: "An irreversible accumulation of DNA -harm- (in terms of mutations) due to the lack of recombination -genetic diversity-. So, we could say that lack of sexual reproduction, and a continuos style of clonal reproduction (that is, the same copy of the organism) with time accumulate harmful DNA changes. DNA changes (mutations) occur by chance, although their ocurrence is regulated by several mechanisms. But in asexual organisms, or when genetic diversity is low, it tends to accumulate a lot.

The gizzard is the muscular organ located between the crop and the small intestine in birds. Its primary function is to mechanically grind and break down food, as birds do not have teeth to chew their food.

The gizzard accomplishes this through strong muscular contractions that crush and grind the food against small stones and grit that the bird has ingested.

Therefore, it is likely that the contents found in the gizzard would be more ground up compared to those found in the crop. The crop is a storage organ located at the base of the bird's neck that serves as a temporary holding place for food before it enters the digestive system. While the crop may soften and partially break down food through the secretion of digestive enzymes, it does not have the same mechanical grinding function as the gizzard.

In summary, the gizzard is the organ responsible for grinding and breaking down food in birds, while the crop primarily serves as a temporary storage organ. Therefore, the contents found in the gizzard are likely to be more ground up compared to those found in the crop.

Varicella Zoster is an infectious viral disease causing chickenpox in children and shingles in grown-ups. Inoculation plays a crucial part in avoidance and lessening complications.

Women and noblemen,

Nowadays, I would like to examine a vital and predominant viral disease known as Varicella Zoster. Varicella Zoster, commonly alluded to as chickenpox, is caused by a varicella-zoster infection. It fundamentally influences children, but can too affect grown-ups who have not been already contaminated.

Varicella Zoster presents as a profoundly infectious sickness characterized by a particular hasty, fever, and common disquietude. The infection spreads through coordinated contact or respiratory beads, making it effortlessly transmissible inside families and communities.

Whereas chickenpox is for the most part a gentle ailment in children, it can lead to more serious complications in grown-ups, pregnant ladies, and people with debilitated resistant frameworks. These complications incorporate pneumonia, bacterial contaminations, and in uncommon cases, neurological complications such as encephalitis.

Luckily, the improvement of a profoundly successful antibody has essentially diminished the frequency of Varicella Zoster around the world. Immunization not as it were secures people from the distress and potential complications of chickenpox, but too makes a difference anticipate the infection from spreading inside the community.

In any case, Varicella Zoster doesn't halt at chickenpox. Once the introductory contamination settles, the infection remains torpid inside the body and can reactivate a long time afterward, causing a condition known as herpes zoster, or more commonly, shingles.

Shingles are characterized by a difficult hasty that ordinarily happens in a single dermatome, regularly along the middle or confront. The reactivated infection can cause critical pain and inconvenience, enduring for weeks or indeed months. Moreover, complications such as postherpetic neuralgia, a persistent torment disorder, can happen, especially in more seasoned people.

To combat the chance of shingles, an isolated antibody called the shingles antibody or herpes zoster immunization has been created. This antibody not as it were makes a difference anticipate shingles but moreover diminishes the chance of postherpetic neuralgia.

In conclusion, Varicella Zoster, enveloping both chickenpox and shingles, could be a viral contamination that has critical suggestions for open well-being. We have made significant progress in reducing the burden of this disease through extensive vaccination efforts.

In any case, ongoing efforts to prevent Varicella zoster from returning to our communities and to protect powerless populations require prompt attention and vaccination.

Much obliged to you for your thought. Let's collaborate to ensure a better future for everyone.

Explanation:

Option 1 is Correct. The region that is missing has a degron, which when recognized by the proper identification protein, ubiquitylates mitotic cyclin in order to complete the cell cycle.

Sequence analysis of the mutant mitotic cyclin reveals that nine amino acids are absent from the molecule's near one end. Considering this knowledge, speculate on the reasons this type of mitotic cyclin would not be destroyed at the start of anaphase.

Silent mutation: Silent mutations alter the bases in a DNA molecule, but they have no effect on the amino acid sequence of a protein. A DNA change known as a missense mutation causes different amino acids to be encoded at a specific place in the resultant protein.

Correct Question:

'Sequence analysis of the mutant mitotic cyclin shows that it is missing a stretch of nine amino acids near one end of the molecule. Based on this information, discuss the possible explanations of why this form of mitotic cyclin is not degraded at the onset of anaphase.

1. The missing segment contains a degron whose detection by an appropriate recognition protein normally targets mitotic cyclin for ubiquitylation.

2. The missing stretch of amino acids contains the lysine to which ubiquitin is normally attached when mitotic cyclin is being targeted for destruction.

3. The removal of a stretch of amino acids could change the conformation of mitotic cyclin so that it can no longer serve as a substrate for the ubiquitylating enzyme complex.

To find the speed velocity, divide the product of 38 and 2 by 20. The result is the speed velocity.

To find speed velocity, we need to divide the distance traveled by the time taken.

In this case, the distance traveled is 38 times 2, which equals 76 units. The time taken is 20 units.

To calculate speed velocity, we divide the distance (76 units) by the time (20 units).

Speed velocity = Distance/Time = 76 units / 20 units = 3.8 units per unit of time.

Therefore, the speed velocity in this scenario is 3.8 units per unit of time.

It's important to note that units were not specified in the question, so the units of measurement for distance and time are unknown.

The result can be interpreted as 3.8 units of distance covered per unit of time.

The non-striped coat is likely a recessive trait. If both parents have striped fur, it is likely that they are both heterozygous for the striped trait.

That means they each carry one dominant and one recessive allele for this trait. When they mate, there is a 25% chance that their offspring will inherit two copies of the recessive allele, resulting in a non-striped coat. This pattern of inheritance is consistent with a recessive trait.
