Answer:

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

Explanation:

The most important function of the nucleic acids is to store and express the genetic information of the cell in the form of DNA (deoxyribonucleic acid).

Answer:

The two problems that the transfer of information from DNA to protein must overcome are:

Explanation:

The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.

The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.

Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.

Explanation:

Scenarios that does not illustrate a danger bats can pose to miners is bats can attack, causing miners to contract rabies.Thus, option C is correct.

Food web has been defined as the natural way of the interconnection of the food chain that has been represented by the help of graphs and it has been shown that in the ecological community who eats whom. The food web has been also known as the consumer consuming system. The main advantage of the food web has the organism present on the top or the organisms who belongs to the higher trophic level can provided food or feed the organisms from lower trophic level or from other food chain.

The permanent food web has been increased due to the presence of large or complex food web. There are mainly three steps in the food web or food chain and they are producers, consumers, as well as  decomposer. The producer belongs to the trophic level, the consumers belongs to the second and third trophic level, and the decomposers belongs to fourth and fifth trophic level.

Since there are more number of  species they have more oppurtunity on which ones to eat  because food webs with many species (biodiverse) are more stronger than those with few species.

Therefore, Scenarios that does not illustrate a danger bats can pose to miners is bats can attack, causing miners to contract rabies.Thus, option C is correct.

Answer:

Carbon Cycle

Everything You'll Have Covered

What role do producers, consumers, and decomposers play in the carbon cycle?

~ Producers synthesize their food through photosynthesis using energy from sunlight and carbon dioxide from the air. Their respiration returns carbon dioxide to the atmosphere. Consumers use the food produced by producers for energy. Their respiration also returns carbon dioxide to the atmosphere. Decomposers break down plant and animal waste products. They also break down dead plants and animals. The decomposing process releases carbon dioxide gas into the atmosphere.

How do fossil fuels and volcanic activities contribute to the carbon cycle?

~ When fossil fuels are burned, carbon dioxide is released into the atmosphere in the form of gas. When volcanoes erupt, carbon dioxide that was in the magma passes into the atmosphere as carbon dioxide gas.

How is carbon returned to the Earth and sea in the carbon cycle?

~ Carbon is returned to the Earth and sea in the form of precipitation after carbon dioxide mixes with rain and snow. Erosion is another way that carbon is returned to the sea. When shellfish die, the carbon that was in their shells collects at the bottom of the ocean and eventually forms sedimentary rocks.

Give one example of a human activity�that could disrupt the�carbon�cycle�as well as the consequences of this disruption.

~ Burning fossil fuels can disrupt the carbon cycle, since they increase carbon dioxide in the air, which can lead to environmental problems such as acid rain.

Photosynthesis is the process by which plants produce their food in the presence of sunlight that is solar energy with the use of carbon dioxide and water. The breakdown is the mechanism  by which plants give their carbon dioxide back.

The end products of photosynthesis are glucose and oxygen that is given back to the atmosphere.

In plants, photosynthesis is the process by which plants prepare their food in the presence of sunlight and glucose is made thus this is the way by which plants are preparing their food and in the case of plants glucose is stored in the form of starch.

With the reactions going on when the cellular respiration reactions are going on at that time the reactions produce enough of carbon dioxide which is given back to the atmosphere thus this dependency helps to interpret the mutual relationship.

Answer:

The King Cobra and the Black Mamba

EXPLANATION:

The black mamba is a species of highly venomous snake belonging to the family Elapidae. It is native to parts of sub-Saharan Africa. First formally described by Albert Günther in 1864, it is the second-longest venomous snake after the king cobra; mature specimens generally exceed 2 m and commonly grow to 3 m

The king cobra, also known as the hamadryad, is a venomous snake species in the family Elapidae, endemic to forests from India through Southeast Asia. It is threatened by habitat destruction and has been listed as Vulnerable on the IUCN Red List since 2010. It is the world's longest venomous snake.

Answer:

The two types of venomous snakes are Elapine snakes, and Viperine snakes. Elapine snakes have shorter fangs and venom that paralyzes the respiratory system. Cobras and coral snakes are Elapine snakes. Viperine snakes have longer hollow fangs and venom that attacks red blood cells. Rattlesnakes are viperine snakes.

Explanation:

Answer:

Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.

In heat transfer by convection, heat energy causes denser materials to sink and causes less dense materials to rise.

Heat transfer refers to the process by which heat energy is transferred from one point at higher temperature to another at lower temperature.

Heat energy is transferred on Earth by the processes of convection, conduction, and radiation.

Thus, during convection, heat energy causes denser materials to sink and causes less dense materials to rise.

Red blood cells have a salt content of 0.9%. When a microbiologist places red blood cells in pure water, osmosis occurs. This results into water molecules . Thus, the correct option is C.

Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential or lower solute concentration to a region of low water potential or higher solute concentration, in the direction which tends to equalize the solute concentrations on the two sides of the membrane.

It is of two types, on the basis of movement of solvent particles, when the solvent moves inside the cell it is called endosmosis which results into turgid cells and the movement of solvent molecules outside the cell which is called exosmosis that results into flaccid cells.

Therefore, the correct option is C.
