Answer:

The answer is C. Wind levels usually remain static in a specific location, so any existing life is not affected much. Biomass contributes to growth as it enriches the soil. Solar (assuming it's referring to the widespread increase in the use of solar energy) could actually be indirectly beneficial to forests. Nuclear fission, however, can cause harm to plants. Some known effects on plant life include stunted growth, reduced germination, and genetic mutations in addition to the direct burning that could be inflicted on plants in some cases.

If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155°

A parallelogram is a quadrilateral (has four sides and four angles) in which both sides are equal and parallel to each other. Opposite angles of a parallelogram have the same measure and the diagonals are equal in length.

If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155° because opposite angles are equal.

Answer:

Some reasons that people give for smoking:
> they believe it reduces stress and anxiety ( scientific studies show this isn't factual and the chemicals within smoking products is only made appealing and or distracting to make the user believe so. It actually heightens stress levels and lowers health levels)
> this sounds cliche but, teens often think its cool or get peer pressured into it. They find themselves wanting to try harmful substances and get addicted. ( in one study there were d r u g s found in smoking products aimed to get the attention of children and young adults. It's all a marketing ploy for business men and women to collect money as you slowly grow more and more breathless)
> lastly, "it's not that bad for you" often, markets and cig stores tell potential buyers its not as bad as other things. Some say its not harmful at all.( Lung disease,gum disease,heart failure,etc. all disprove this. Each year about 480,000 people die from the affects of smoking)

Explanation:

Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called Cheyne-Stokes respiration. It is an abnormal respiration cycle.

The Cheyne-Stokes respiration is an abnormal type of respiration cycle characterized by apnea.

Cheyne-Stokes respiration refers to an unnatural manner of breathing that is generally associated with sleep.

Cheyne-Stokes respiration is characterized by fast abnormal breathing cycles and then slow apnea abnormal breathing cycles.

Answer:

Kreb cycle is the sequence of reactions by which most living cells generate energy during the process of aerobic respiration. It takes place in the mitochondria, using up oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.

Explanation:

Definition:

A cycle of reactions catalyzed by enzymes in which the pyruvate derived from nutrients and converted to Acetyl Coenzyme A is completely oxidized and broken down into carbon dioxide and water to produce high-energy phosphate compounds, which are the source of cellular energy.

In eukaryotes, the Krebs cycle reactions take place in the mitochondrial matrix, a dense solution that surrounds the mitochondria crests: in addition to water, the matrix contains all the enzymes necessary for the biochemical reactions of the cycle, coenzymes, and phosphates.

Equation:

The overall reaction for the citric acid cycle is as follows: acetyl-CoA + 3 NAD+ + FAD + GDP + P + 2H2O = CoA-SH + 3NADH + FADH2 + 3H+ + GTP + 2CO2.

Answer:

small thing about climate change

Explanation:

Climate Change is trapping Co2 into the earth's atmosphere, raising the temperature of the Earth. Because of that, it's melting the Antarctic and killing millions of animals. Not only that, but it's also causing droughts, and usually droughts are the cause(s) of famine which kill millions of not only animals, but humans too.

Answer: The answer is B. (It stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids.)

Explanation: I took the test and this was the answer! :)

The function of DNA (deoxyribonucleic acid) is to store and transmit genetic information from one generation to the next, and it stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids. That is the last option.

DNA is a molecule composed of long chains of nucleotides. A nucleotide is made up of three components: a sugar molecule, a phosphate group, and a nitrogenous base. The process of gene expression begins with the transcription of DNA into RNA (ribonucleic acid). RNA is a molecule similar in structure to DNA but with a few key differences, such as the presence of the nitrogenous base uracil (U) instead of thymine. DNA also plays a role in the regulation of gene expression. Certain regions of DNA, called promoters and enhancers, help to control when and where a gene is expressed.

Hence, it stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids. That is the last option.

Answer:

processivity

explanation

RNA polymerase is said to have high processivity, meaning that it can catalyze thousands to millions of reactions without releasing the DNA template

RNA polymerase is said to have high A) processivity, meaning that it can catalyze thousands to millions of reactions without releasing the DNA template.

Processivity refers to the ability of an enzyme to remain attached to its substrate and catalyze multiple consecutive reactions without dissociating. In the case of RNA polymerase, it is responsible for synthesizing RNA molecules by using a DNA template.

RNA polymerase exhibits high processivity, meaning that once it binds to the DNA template, it can catalyze the formation of RNA molecules for an extended period without releasing the DNA template. This allows for the efficient synthesis of long RNA strands.

During transcription, RNA polymerase moves along the DNA template, unwinding the DNA double helix and adding complementary RNA nucleotides to the growing RNA chain. It remains attached to the DNA template throughout this process, continuously elongating the RNA molecule.

The high processivity of RNA polymerase is essential for the accurate and efficient transcription of genes. It ensures that the RNA molecule is synthesized without interruptions or premature termination. This processivity allows RNA polymerase to transcribe entire genes or long stretches of DNA without dissociation, facilitating the synthesis of functional RNA molecules.

Overall, the high processivity of RNA polymerase contributes to the fidelity and efficiency of transcription, allowing for the synthesis of RNA molecules that faithfully represent the information encoded in the DNA template.

Explanation:

The correct option is "D" Migration.

Since the term aquaculture mainly refers to the cultivation of aquatic organisms in controlled aquatic environments for any commercial, recreational or public purpose. whereas external organisms are added to an ecosystem in order to raise their number keeping in mind the availability of food for them.

For the creation of new aquatic ecosystem cargo ship hulls, recreational boats, organisms escaping from the aquariums can be useful as these methods are non-natural and are disturbing the original productivity and stability of the ecosystem.

Migration is a natural phenomenon in which non-native organisms move to another habitat in search of food required for survival.

Thus, Migration is not a way that nonnative organisms are introduced to new aquatic ecosystems related to commerce.
