In rigor mortis, muscle tissue becomes locked in position because myosin heads are tightly attached to neighboring actin thin filaments. This lock-up is prevented in living muscle because ordinarily myosin is rapidly displaced from the thin filament by:_________.A. binding of a new molecule of ATP B. hydrolysis of ATP C. release of ADP after ATP hydrolysis D. release of phosphate after ATP hyrdolysis

Answers

Answer 1

Answer:

The correct answer is option A. binding of a new molecule of ATP.

Explanation:

Actin and myosin are complementary filaments present in muscle, actin is thin and myosin is a thick filament, these two filaments are responsible for the movement by muscle contraction and relaxation. Actin and myosin head shows great affinity towards one another.

Myosin heads are tightly attached to neighboring actin thin filaments due to its affinity to actin, however, myosin at other pockets also show a huge affinity for ATP. If myosin is bound to actin the affinity for ATP is changed and if new ATP bounds to the empty pockets it changes the conformation of myosin and prevents lockup or binding of the actin-myosin protein.

Answers

Answer:

Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted.

Explanation:

Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.

- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.

- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.

Draw a flow chart that explains how DNA is used to create an organism. please use the words: DNA, gene, protein, cell, tissue, organ, organism.

Answers

Answer:

Please find the flowchart attached as an image

Explanation:

DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.

PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.

Multicellular organisms (like us) increase the number of their cells through cell division. One cell divides (parent cell) and becomes two new cells (daughter cells).

what is accuracy, precision, and reproducibility ? and why are they so necessary in conducting/designing experiments

Answers

Answer:

- Accuracy is the degree by which the measures obtained in an experiment and/or observational procedure are associated with true values.

- Precision is the level of reproducibility that these measurements exhibit in the same (constant) conditions.

- Reproducibility indicates the level of agreement of the results when they are obtained by different researchers by applying the same experimental and/or observational procedures.

Explanation:

In a scientific investigation, it is imperative to achieve higher levels of accuracy and precision when realizing measurements because it ensures that the information is correct (without mistakes). Thus, researchers always try to use better equipment and instrument to make their measurements. Reproducibility is important because it is the only condition that scientists can guarantee to other researchers when they arrive at a result.

A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil.she then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill,and the third is placed under a lamp with a green bulb.she records the height of each plant every day for three months.


What is the independent variable in this experiment?

Answers

Answer:

The amount of light they receive.

Explanation:

In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.

The independent variable in this experiment is the amount of light received by each plant.

What is an independent variable?The experimenter manipulates or alters the independent variable, which is expected to have a direct effect on the dependent variable.For example, here the amount of light given to each plant is different and will have an effect on the growth of pea plant.In an experiment, the dependent variable is the variable that is being tested and measured, and it is 'depending' on the independent variable. here the growth of pea plant is dependent variable.

c. at least one of the lariats
d. the poly(A) tail.
e. exon 1
f. all exons
g. some introns

Answers

Answer:

a. the primary transcript

Explanation:

The first step in RNAm maturation is the modification of the 5' end of the transcript via the addition of a structure called a cap or 7-methyl guanosine cap. The enzymes responsible for the formation of this cap are recruited to the phosphorylated C-terminal domain after the addition of the first twenty to thirty nucleotides of ARN. The formation of the cap is started by the addition of a GTP molecule oriented inversely to the 5' end nucleotide on RNA. Then methyl groups are added to this G residue and to the ribose forms of one or two nucleotides located on the 5' end. All these reactions take place in the nucleus when the mRNA is found as a primary transcript.
