Answer: DNA codes for our genotype, which is the genetic representation of out traits. There are multiple kinds of RNA but it is mostly used to aid the replication of DNA.
Explanation: DNA is the strand of nucleic acid, sugars and phosphate group, that is found in the nucleus and mitochondria of every cell. It codes for our genotype, which is essentially the written representation of our traits. There are multiple kinds of RNA but they are mostly used to replicate DNA, they are single stranded as opposed to the double stranded DNA and include the nitrogen base uracil (U), instead of thymine (T). mRNA, tRNA and dsRNA are commonly used to replicate and regulate the DNA sequence.
Answer:
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell 's activities, while RNA converts that code into proteins to carry out cellular functions.
Explanation:
RNA:
The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.
DNA:
The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

. Distinguish between gross primary productivity and net primary productivity. Explain how net primary productivity affects the number of consumers in an ecosystem and on the earth. List two of the most productive ecosystems or aquatic life zones and two of the least productive ecosystems or aquatic life zones. Use the concept of net primary productivity to explain why harvesting plants from estuaries, clearing tropical forests to grow crops, and harvesting the primary producers in oceans to feed the human population are not good ideas.
Answer and Explanation:
The gross primary productivity corresponds to the sum of all the energy produced by the plants (primary producers) during the photosynthesis process. The net primary productivity, corresponds to the gross primary productivity value, even the energy value used by the plants in the metabolic processes that they present, in this way, we can conclude that the net primary productivity is the energy that is available for the living beings that consume the vegetias.
The ecosystems with the highest level of productivity are those that have a large number of vegetables with full access to the sun, in this case, we can mention forests and ecological parks. On the other hand, ecosystems with lower levels of productivity are those with a low number of plants, such as cities and areas with deforestation.
Because of our need to consume energy from net primary productivity, we are constantly harvesting vegetables and some photosynthetic water products to use in our food. However, this causes us to remove vegetables from nature and decrease the amount of gross primary productivity that ecosystems would have, and, consequently, decreasing the amount of net primary productivity that we need so much.

Which of the following does NOT describe a protein function? A. Enzyme B. Short-term energy C. Antibody D. Endorphin
Answer:
B. Short-term energy
Explanation:
A, C, and D are all protein functions.
B is characteristic of carbohydrates.
Proteins are the macromolecules that act as enzymes, antibodies, and endorphins. It does not act as short-term energy. Thus, option B has been correct.
What are proteins?Proteins are polymers that are large molecules and are essential for several bodily activities, including immune reactions, hormone synthesis, growth, development, energy, and enzyme activities.
Enzymes are made of proteins that speed the biochemical reactions, antibodies are made of proteins that are immunoglobulins and act as a defense for the body. Endorphins are the hormones that are synthesized in stress and painful conditions.
Proteins just do not provide short-term energy but provide energy that can suffice for a longer period of time so that it can perform the various functions and activities in the cell.
Therefore, option B. proteins are not short-term energy.

Plants remove carbon from the atmosphere in the form of CO2 and store it in their structures. How can rapid deforestation affect the carbon cycle? What can be done to reduce the effects? Explain.
Answer:
Explanation:
Deforestation affects carbon cycle through the Greenhouse gas effect and global warming. Green plants, trees and forest helps to balance the amount of Carbon in the atmosphere, carbondioxide is used up by plant through the process of photosynthesis in which plants make their own food. When there is excess amount of carbon dioxide in the atmosphere as a result of deforestation ‘blanket’ of carbon dioxide is formed which traps heat and prevents it from leaving the earth surface in the atmosphere. This accumulated heat leads to global warming in the environment.
More trees should be planted to prevent rise in atmospheric a carbon and deforestation should be prevented.
Answer:
Deforestation has an effect on the Carbon Cycle also known as the Greenhouse gas effect and global warming. Trees and forest balance the amount of Carbon in the atmosphere through the process of photosynthesis in which plants make their own food with carbon dioxide. And when we remove the plants that turn CO2 into breathable air we have more CO2 over all.
How does an organisms life begin?
Answer:
Living organisms undergo growth and development. Every living organism begins life as a single cell.
Answer:
The life of an animal organism, obviously, begins at conception. But human life begins only at the moment that the animal has a mind. In some, very fast, developers this can happen before the age of one year; in a large majority of cases this happens between two and three years of age.

The replication cycle of T7 virus has several things that none of the other virus replication cycles include. What is one of these things? I cant find anything on google shhssgxhahshsb or im just lazy
Answer:
Lysogenic replication cycle is one unique process in T7 virus replication.
Explanation:
The T7 virus is a virus that attacks bacteria ( bacteriophage). Unlike other viruses (plants and animals viruses), it replicates within the host cell by means of two cycles: the lytic replication cycle and the lysogenic replication cycle.
Virulent phages replicate through the lytic replication cell and this lead to the death of the cell through cell lysis.
The lysogenic replication cycle involves bacteriophages known as temperate bacteriophages. Temperate bacteriophages can become part of a host chromosome forming a prophage. The prophage replicates with the formation of daughter cells with incorporated viral genetic materials until when induced to enter into the lytic stage thereby producing new viruses which then exit the host cell by cell lysis.
This process of incorporation into the host cell genome is known as lysogenic replication and is unique to the bacteriophages.
Viruses are neither living nor dead organisms. The viruses require a host to replicate. The virus follows the lysogenic or lytic cycle to replicate. The T7 virus follows the lysogenic replication pathway.
The T7 virus follows the lysogenic pathway, in which the nucleic acid of the bacteriophage is incorporated into the host genome. The T7 virus intervenes on the bacteriophage genome.
In the lysogenic cycle, bacteriophages can become part of the host genome. This genome is then known as prophage. Prophage replicates and forms the daughter cells with the altered genetic material of the host.
The new cells produced are released by the lytic cycle, in which the cell produces new cells by lysis.
Thus, the incorporation of the host cell genome in the bacteriophage via the lysogenic cycle is a unique feature of a virus, T7.

Give an example of how politics can affect science?
Answer:
Politics can affect and even dictate the manner in which science is done. For example, passing laws that limit whether embryos can be used in stem cell research. Politics can allocate funding to various scientific causes. Politics can create a great research environment in the universities. And so on.
In extremes, politics can even make entire areas of science off limits. In the early twentieth century, lots of very smart and decent people were eugenicists. Politics (in particular, the unbelievable moral horror that was Nazism and the Holocaust) change

The dependent variable should be the rate of growth of the plants
The constant doesn't change so other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.
The controlled variables might be things such as the the quality of soil and the amount of water given to the plants. If these factors were not constant, and certain plants received more water or better soil than others

What is the purpose of greenhouse gases?
Answer:
A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect[1] on planets. Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F),[2] rather than the present average of 15 °C (59 °F).[3][4][5] The atmospheres of Venus, Mars and Titan also contain greenhouse gases.
