Water sticks to the sides of a glass tube, but mercury forms a rounded, bubble-like surface at the top of the liquid. Which is probably greater in mercury-cohesion or adhesion. Explain your answer.
Please help! The quarter ends tomorrow and I need to get this done.
Answer:
Water wets glass and spreads out on it because the adhesive forces between the liquid and the glass are stronger than the cohesive forces within the water.

Gene Cloning is referred to as producing similar or identical copies of the same recombinant molecule. So, the correct option is (D).
What is Gene Cloning?Gene cloning is defined as the process in which the gene of interest is copied from the extracted DNA and inserted into the host to replicate the same.
The steps of gene cloning are:
Isolation or extraction of genes of interest using restriction enzymes.Selection of a suitable vector or plasmid carrying the gene of interest.The DNA fragment is then introduced into the desired vector.Transformation of donor DNA into a suitable host cell.The final step is to isolate colonies of transformed cells.Thus, Gene Cloning is referred to as producing similar or identical copies of the same recombinant molecule. So, the correct option is (D).

When muscle cells run out of____________, they resort to lactic acid fermentation for a supply of energy. A. Carbon Dioxide B. Oxygen
Answer:
B oxygen
Explanation:
When your body runs out of oxygen, or your other systems can't deliver oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead.
Lactic acid fermentation is the energy source used by muscle cells when their supply of oxygen runs low.
What is muscle cell?A muscle cell is sometimes known as a myocyte because smooth muscle cells and cardiac muscle cells are both very small cells. The long, threadlike cells of skeletal muscle with many nuclei are known as muscle fibers. Muscle cells are derived from myoblasts, which are embryonic progenitor cells.The cytoplasm and cell membrane of a muscle cell are known respectively as sarcoplasm and sarcolemma. The sarcoplasm contains myoglobin, which is a site for storing oxygen, and glycogen in the form of granules in the cytosol, which is an energy source.When your body runs out of oxygen or when your other systems are unable to transfer oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead of oxygen.To learn more about muscle cell refer to:

is a chemical substance that is produced in substantial quantities, and is reasonably expected to be released in to the environment in substantial quantities a risk trigger, standard trigger, or an exposer trigger?
Means that the EPA has made a determination that a chemical or biological agent may present an unreasonable risk both in toxicity and exposure.
a. exposer trigger
b. standard trigger
c. risk trigger
Answer:
c-risk trigger
Explanation:
The Risk Evaluation process is the second step, following Prioritization and before Risk Management, in EPA’s existing chemical process under TSCA. The purpose of risk evaluation is to determine whether a chemical substance presents an unreasonable risk to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation. As part of this process, EPA must evaluate both hazard and exposure, exclude consideration of costs or other non-risk factors, use scientific information and approaches in a manner that is consistent with the requirements in TSCA for the best available science, and ensure decisions are based on the weight-of-scientific-evidence.
Which statements about wells are true? Check all that apply.
Wells bring groundwater from the unsaturated zone to the surface of the water.
Wells need to be drilled below the water table.
If water is pumped from a well too quickly, the well may run dry.
Water from wells is generally not safe to drink.
Water gushes from artesian wells due to pressure.
Answer:
Wells need to be drilled below the water table.
If water is pumped from a well too quickly, the well may run dry.
Water gushes from artesian wells due to pressure.
Explanation:
The statements that assert a true claim regarding the wells would be as follows:
b). Wells need to be drilled below the water table.
c). If water is pumped from a well too quickly, the well may run dry.
e). Water gushes from artesian wells due to pressure.
The above statements offer appropriate claims regarding the wells that they are required to be penetrated down the water table because it assists in striking the water from the lower levels as well. The next statement asserts that water must be transported from wells in a hurry because it can impact the yielding ability of the wells.The streaming of water from the artesian wells is primarily because of the pressure as it helps in the release of the water effectively.Thus, options b, c, and e are the correct answers.

The name “amino acid” is derived from the amino group and carboxyl-acid-group in their basic structure. There are 21 amino acids present in proteins, each with a specific R group or side chainAll organisms have different essential amino acids based on their physiology.
Answer:
Because they are made of an amino group (NH3) and carboxylic acid group ( COOH)

How is sucrose produced from the end products of photosynthesis?
Sucrose is the end product of photosynthesis and the primary sugar transported in the phloem of most plants. ... SuSy catalyzes the reversible cleavage of sucrose into fructose and either uridine diphosphate glucose (UDP-G) or adenosine diphosphate glucose (ADP-G).
Sucrose is produced from the end products of photosynthesis by the fact that when oxygen is liberated in the atmosphere and hydrogen facilitates the assimilation of carbon dioxide in the dark reaction, which ultimately forms sucrose, starch, and maltose.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
Calvin cycle stimulates the synthesis of Sucrose. In the cytosol, triose phosphate gest converted into Fructose 1, 6- bisphosphate which ultimately forms Glucose 1- phosphate that leads to the formation of UDP Glucose and ultimate sucrose if formed.
Therefore, the process of formation of sucrose from the end products of photosynthesis is well described above.
