what is the function of DNA, and how does the structure of DNA influence its function

Answers

Answer 1
Main function of dna is to store all long term storage of information
Answer 2
Final answer:

DNA serves functions in inheritance and protein synthesis. Its structure, a double helix, determines its function through the arrangement of nucleotides.

Explanation:

DNA serves two essential functions: inheritance and protein synthesis. DNA is responsible for passing genetic information from parent to offspring, and it is replicated with high accuracy to maintain the integrity of this information. DNA also directs the construction of proteins necessary for cell growth and reproduction.

The structure of DNA influences its function through the arrangement of nucleotides. DNA is composed of two strands that form a double helix. The sequence of nucleotides along the strands encodes the genetic information. The specific base pairing between nucleotides ensures accurate replication and protein synthesis.

why are biologists and ecologists interested in determining the sizes of populations of organisms ms other than humans

Answers

My answer would be to see how large a difference between the size of the human population and the other organism in question.

The Biologists and Ecologists interested in determining  the sizes of population of organisms other than Humans because studying various kinds of plant, animal, fungal, and even bacterial populations leads to find the answer to  how the population interacts with its physical environment and with other species.

By studying population size ecologists can see how these populations have changed and may be able to predict how they're likely to change in the future. Monitoring the size and structure of populations can also help ecologists manage populations—for example, by showing whether conservation efforts are helping an endangered species increase in numbers.

Size and density are both important in describing the current status of the population and, potentially, for making predictions about how it could change in the future, for example:

Larger populations may be more stable than smaller populations because they’re likely to have greater genetic variability and thus more potential to adapt to changes in the environment through natural selection. A member of a low-density population—where organisms are sparsely spread out—might have more trouble finding a mate to reproduce with.

So, the biologists and ecologists are interested in determining the sizes of population of organisms because it helps in studying the ecological effects, and environmental effects of the population size on the ecosystem.

What is astronaut?

A person who has undergone specific training to travel to space is known as an astronaut.

The duties of an astronaut aboard a spaceship can vary. Usually, a pilot and a commander work together to lead the mission.

The term "astronaut," which is derived from the Greek words for "star" and "sailor," is frequently used to refer to someone who has travelled through space.

More specifically, in the West, the term "astronaut" refers to space travellers from the United States, Canada, Europe, and Japan.

Six Apollo flights between 1969 and 1972 returned 382 kilogrammes (842 pounds) of lunar rocks, core samples, pebbles, sand, and dust. 2200 unique samples from six different Moon exploration locations were returned by the six space missions.

Final answer:

Scientists looked for organic compounds, microfossils, and potential microorganisms in the lunar samples, using thorough laboratory analyses. No signs of life were found on the Moon. The samples still provide valuable information for scientific research about lunar history.

Explanation:

When the Apollo astronauts brought back samples of the Moon's surface, scientists searched for evidence of life by examining these samples for organic compounds, microfossils, and any possible living microorganisms. They used various types of analyses, such as microscopy, chemical analysis, and culturing techniques. Despite the detailed examination of nearly 400 kilograms of lunar material, no signs of life were found on the Moon. The studies did provide invaluable insight into the Moon's composition and history, including its formation about 4.5 billion years ago. Since then, the samples returned from the Apollo missions have continued to be of scientific value, enhancing our understanding of lunar geology and the early Solar System.

The comprehensive study of lunar soil and regolith also confirmed that it had been pulverized by impacts, as suggested by the Surveyor missions, and was firm enough to support the Apollo Lunar Surface Experiment Package (ALSEP) which operated for years after deployment. Such detailed analysis has been crucial to expanding our knowledge of the Moon and has left a lasting legacy, with the lunar material collected still providing data for current scientific research.

Select all that apply. _____ trigger other proteins and enzymes to stimulate cell division. External and internal stimuli Regulating protein agents Activators and inhibitors Metabolic pathways

Answers

The right answer is Regulating protein agents.

The regulating protein agents they are talking about is certainly the cyclin, especially cyclin B.

Cyclins have no enzymatic activity, they are regulatory proteins necessary for Cdk to be enzymatically active.

The activation of the Cyclin B / Cdk1 stock is the result of a series of complex and interdependent reactions:

When replication is complete, the Cdc25 phosphatase is no longer sequestered in the cytoplasm and passes into the nucleus, and at the end of the G2 phase, the Cdc phosphatase is activated, probably by phosphorylation by the Polo kinase. Cdc 25 then acts to remove the two phosphates inhibitors Cyclin B / Cdk 1 (after that, there is a process of self-activation).

Cyclin B / Cdk 1 complexes, once activated, allow entry into mitosis. For this, they intervene by triggering a number of phenomena that take place at the beginning of mitosis, that is to say in prophase.

Why do enzymes generally only bind to one type of substrate?

Answers

Enzyme and substrate works in a lock and key hypothesis. Like a key fits to it's lock
Enzyme has a 3D shape which is precise. The polypeptide chain of the enzyme molecule folded to form a 'pocket' called an active site.
The active site of an enzyme​ has a distinctive shape and charge that complement to it's substrate.
The shape of substrate must fit the enzyme only the reaction will occur. This explains why enzymes are highly specific.

Explanation:

Enzymes are proteins that increase the reaction rate that occurs within the cells.

enzymes generally only bind to one type of substrate because the active site of the enzymes has a certain shape and as per lock and key model, the enzymes have to be of specific shape the same as the substrate to get fit.  

Enzymes have active sites, where the substrate gets fits when the reaction occurs.It means that enzymes generally only bind to one type of substrate and they are highly specific for their substrate.

C. a living thing dies and its skeleton is left exposed to the elements.
D. a living thing dies and radioactive element breaks down its body.

Please help I am so confused!!

Answers

It would be A, because a fossil forms after an animal dies, and hundreds to thousands of years of soil or sediment coversit's body, preserving it. :)

Answer:

The answer is A) a living thing dies and sediment is very slowly deposited on top of its body.

Explanation:

The formation of a fossil depends a lot on the chemical composition of the organism that has died. Generally, the hard materials of an organism such as bones tend to have a greater amount of minerals within their composition, which facilitates the formation of a fossil. In order for a fossil to form, it is necessary that all the soft tissues of the organism have disappeared and sedimentation of the organism occurs, which prevents decomposition. This fossilization process occurs in thousands of years.

What is the common name of this gas, N2, the most prevalent in our atmosphere? A) sodium B) nickel C) nitrogen D) oxygen

Answers

C) Nitrogen
I absolutely positively positive about this

Answer: The correct option is C) Nitrogen.

Nitrogen ( N₂) is the most prevalent gas in the atmosphere. It contributes 80% in the atmosphere. It is a highly stable gas because it contains three bonds between the two nitrogen atoms. So, it requires high energy to break these chemical bonds.

Nitrogen is the basic nutrient for the survival of all life forms. It is present in bio-molecules like proteins and DNA.

Nitrogen gas can not be used as such by the plants and animals. Therefore, it is converted into other forms so that plants and animals can utilize it. The process of conversion of N₂ into other biologically available form is termed as Nitrogen fixation.

Scientists must always endeavor to avoid biases in their experiments. Biases can impede the objectivity of the scientist and the validity of the experiment's results.

Explanation:

A scientist must always try to avoid biases in scientific experiments. A bias is a prejudice in favor of or against one thing, person, or group compared with another, usually in a way that's considered to be unfair. Biases can affect the objectivity of the scientist and the credibility of the experiment. For example, if a scientist is testing a new drug and they unconsciously favor positive results because they want the drug to succeed, that can introduce bias into the process, skewing the results.

I think both Meg and Rachel applied the same force because the speed was the same

Meg and Rachel applied the same force because the speed was the same amount of the force. Thus, option D is correct.

What is force?

In general language we can say that push or pull is called force.

According to newton second law of motion force is rate change of momentum it means

F= d/dt×(mxv)

Where m is mass and v is velocity

But in general case mass is constant.

So ,Force

F= mxd/dt×(v)

Since we know that rate change of velocity is acceleration.

Then we can say that

F= mass x acceleration

S.I unit of force is Newton

1 Newton = 1kg×m/sec^2.

Force and acceleration is a physical quantity which have both i.e magnitude and direct it means both are vector quantity. According to newton second law of motion force is rate change of momentum it means

F= d/dt×(mxv)

Therefore, Meg and Rachel applied the same force because the speed was the same amount of the force. Thus, option D is correct.
