Which of the following is not a role of DNA?
A. Transmitting Information
B. Storing Information
C. Copying Information
D. Creating information
Creating information is not a role of DNA.
What are the functions of DNA?DNA or the deoxyribonucleic acid is the genetic material present within the humans and almost all the species living. DNA does the function of storing information as genetic information within an organism is stored within the molecules of DNA.
At the time of cell division, all of the information within a cell needs to be copied perfectly. Therefore, DNA is the molecule, which can be replicated to produce almost the perfect copies of itself. The transmission of genetic information to the next generation is done with the help of DNA in the form of a sequence of nucleotides.
DNA performs all the above mentioned functions, however, it does not play any role in creating information.
Thus, the correct answer is option D, that is, creating information.

Which event in Earth’s history most directly allowed life to exist on land? Earth’s temperatures increased, causing widespread evaporation. Earth collided with a large object, forming the moon. Single-celled organisms released oxygen into the air when they photosynthesized. Single-celled organisms absorbed harmful gases from the air when they first formed.
Answer:
c: Single-celled organisms released oxygen into the air when they photosynthesized.
Explanation:
got it right on edge. also if there were no oxygen animals and humans could not live
The event in Earth’s history that most directly allowed life to exist on land is "Single-celled organisms released oxygen into the air when they photosynthesized." Thus, the correct option is C.
What are Single-celled organisms?Single-celled organisms may be defined as those organisms that are constructed by only one cell. This single cell carries out all of the functions needed for the organism. They lack compartmentalization.
Single-celled organisms mainly bacteria evolve themselves in such a way that they released oxygen into the air when they photosynthesized. Such bacteria are known as photosynthetic bacteria.
These bacteria are only the source that brings this diversity among living entities on the earth's surface by making the availability of oxygen on this planet.

B. All of the living and nonliving things that interact in and around a
lake
C. All of the trout that live in a lake
D. All of the fish, bacteria, and mammals that live in a lake
SUBMIT
Answer:
Explanation:
First, let’s define population. A population is all of the organisms of the same species that live in a certain area.
Now, let’s analyze the answer choices.
A: All of the different kinds of fish that live in a lake.
This is not a population, because a population is one species, and this is all the different species of fish.
B. All of the living and nonliving things that interact in and around a lake.
This is also not a population. A population is just one species, while this includes all the biotic and abiotic factors.
C. All of the trout that live in a lake.
This is a population. Trout are one species, and it is all the trout in one specific area.
D. . All of the fish, bacteria, and mammals that live in a lake
This is not a population. Fish, bacteria and mammals are too many species for a population.
Therefore, the correct answer is C. all of the trout that live in a lake.
All of the trout that live in a lake is a population of trout. Therefore, option C is correct.
A population refers to a group of individuals of the same species that inhabit a specific geographical area and have the potential to interbreed. A population consists of all the organisms of a particular species that live and interact within a defined area.
Population biology is a branch of biology that focuses on studying populations and their characteristics, dynamics, and interactions. It involves examining factors such as population size, density, distribution, age structure, genetic variation, growth rate and changes over time.

C) circulatory-transports materials for energy
release in body cells
D) respiratory-collects waste material for digestion
Answer:
C) circulatory-transports materials for energyExplanation:
Excretory system - the elimination of wastes produced by homeostasis.
Digestive system - the conversion food into energy and basic nutrients to feed the entire body.
Circulatory system - carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Respiratory system - allows your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.
I really need help with this one
Answer:
The prey population, the rabbits, and the predator population, the foxes, directly rely on one another. As the rabbit population grows, more food becomes available for the fox population to grow, therefore the fox population grows. The rabbit population now has more predators, but an assumed constant amount of food, causing the rabbit population to fall. The rabbit population falls and less food becomes available for the fox population, so the fox population falls. Both the predator and prey species are majorly responsible for the carrying capacities of the other species.

what do u mean by this chromosones contain information of inheritance of character from parent to next genration in the form of dna
Answer:
Explanation:
DNA are the building blocks of chromosome. Think about a blueprint. Blueprint contain instructions of how to build something, the actual instructions are the drawing and those drawings are housed on the blue paper.
So if you connect that analogy to this, DNA is actually the code that tells your cell how to do, what to do and such, they are actual genetic codes with bases such as Adenine, Guanine, Cytosine, and Thymine arranged in a double helix pattern. The chromosomes are the structures that are a result of arrangement of billions and billions DNA bases, thus they are the structures that house DNA and gene (part of DNA that codes for stuff)

Describe the path of an oxygen atom through four reservoirs of the oxygen cycle. Explain the process involved in the transfer between these reservoirs. Also, note the reservoirs in the path where the oxygen atom bonds to a carbon atom.
Answer:
The four main reservoirs of oxygen cycle are terrestrial biosphere, marine biosphere, lithosphere and atmosphere.
Explanation:
Oxygen is present about 21 % in the atmosphere which comes to the earth surface i. e. terrestrial biosphere where animals and microbes use this oxygen for the process of respiration while plants are the only organisms which produces oxygen in the process of photosynthesis and this oxygen goes to the atmosphere. This atmospheric oxygen also dissolve in water which is used by the marine animals. Oxygen atom is also present with carbon atom in the form of food molecules such as glucose which is produced inn the process of photosynthesis.
The oxygen cycle is a biogeochemical cycle, in which oxygen is circulated through the lithosphere, atmosphere, rhizosphere, and biosphere. The amount of oxygen present in the Earth's atmosphere is 21%.
The oxygen's primary reservoirs are the biosphere, atmosphere, and lithosphere.
The atmosphere or the air constitutes 21% of the oxygen. The organisms present on the terrestrial surface consume oxygen via respiration.
In the biosphere, autotrophs like plants produce oxygen via photosynthesis. The oxygen is then delivered to the atmosphere, where it is again utilized by terrestrial organisms.
The oxygen when dissolved in the water is used by marine organisms in the form of dissolved oxygen.
In the lithosphere, the oxygen is circulated through chemical weathering, which the formation of iron oxides. Chemical weathering can lead to the release of oxygen in the atmosphere.
Therefore, the oxygen can be circulated through terrestrial organisms, marine animals, the lithosphere, and the atmosphere through different processes like weathering and photosynthesis.
