Why do scientists use a single system of units?
A. Scientists use a single system to prevent miscommunication.
B. Scientists have their favorite forms of units.
C. One scientists might have a better measurement than the other.
D. Scientists don't make enough measurements to need more then one system.

Answers

Answer 1

Answer:

The answer is A

Explanation: When it comes to using different types of units rather it is SI or NM they want to make sure they got the measurements right they don't want any mistakes when it comes to creating an experiment, data and report that can lead to a lot of miscommunication with other professional scientists. The other answers provided on here didn't really make sense so I believe the answer to this is A

How many valence electrons does carbon have? Is this atom satisfied? Explain.

Answers

Answer:

4 valence electrons

Explanation:

Because of the relative stability, these atoms often form covalent bonds rather than ionic bonds that need a charge. One example is Carbon. It has 4 valence electrons, so it can make a 4+ or a 4- charge.

Answer:

Carbon has 4 valence electrons. It is not satisfied. To be satisfied, it needs to covalently bond with 4 electrons to achieve octet (8 valence electrons).

What is the role of creatine kinase in the myofibril?

Answers

Answer:

Creatine kinase (CK) has several functions in cellular energy metabolism. It catalyzes the reversible transfer of high-energy phosphate from ATP to creatine, facilitating storage of energy in the form of phosphocreatine.

The evidence suggests that the myofibrils' creatine kinase is sufficient to maintain typical tension and relaxation, typical Ca sensitivity, and typical kinetic properties.

What is myofibril?

On the long axis of the myocytes, groups of myofibrils—long contractile fibers run parallel to one another (long single multinucleated cells that combine to form the muscle).

On the cell's long axis, the myocytes are situated next to one another in parallel.

Creatine, a molecule found in your muscle cells that aids in the production of energy by your muscles, needs a phosphate group added to it by CK.

Creatine becomes the high-energy molecule, phosphocreatine, which your body uses to produce energy, when CK attaches phosphates to it.

According to the research, the myofibrils' creatine kinase is enough to keep their regular kinetic features, like tension and relaxation and Ca sensitivity, in place.

Thus, this is the role of creatine kinase in the myofibril.

What is a substrate?
a molecule that acts as a catalyst
a place on the enzyme where the reaction occurs
a place on the product where the enzyme fits
a reactant that is catalyzed by an enzyme

Answers

Answer:

D. a reactant that is catalyzed by an enzyme

Explanation:

A substrate is a reactant that is catalyzed by an enzyme. Therefore, the correct statement is option D.

What is a catalyst?

A substrate is a reactant molecule that binds to the active site of an enzyme and the enzyme then chemically transforms the substrate through a series of catalytic reactions.

Enzymes are the catalysts that are used to increase the rate of biochemical reactions by lowering down the activation energy that is required for the reaction to occur. The substrate when binds to the active site of the enzyme, it forms an enzyme-substrate complex followed by its conversion into one or more products. When the product is formed, enzyme gets released from the product.

A catalyst is a substance which is used to lower down the activation energy required by the reaction, thereby, increasing the reaction rate to form a product.

Therefore, substrate is a reactant that is catalyzed by an enzyme.

Bacteria are unicellular organisms that are very tiny. Bacteria can be found practically anywhere on Earth and play an essential role in the ecosystems that exist there. Some animals are able to survive in environments with both high temperatures and high pressures.

Both plant and animal cells store their genetic material in the form of chromosomes, which are linear structures. Bacteria do not possess a truly organized nucleus and instead contain a single chromosone that is round. Plasmids are tiny circular pieces of genetic material that can be carried by some bacteria. These plasmids carry additional genetic material.

What most likely happened to a species that became extinct and are only found as fossils?

Answers

Answer:

Millions of years from now, paleontologists may dig into Earth and uncover fossils from our own time. They may, like scientists today, construct a chronology of what came before them, watching past species popping into—and later out of—existence. Today, humans are continually driving species to extinction—by one estimate, almost 500 vertebrate species have gone extinct in the past 100 years—but will those future scientists be able to tell? New research suggests that it might not be easy: Only a small proportion of these human-caused extinctions will leave behind a fossil trace—and the most threatened species are the ones least likely to be preserved for posterity.

The history of life on Earth is punctuated by what researchers call the “Big Five” mass extinctions, a group that includes the dinosaur-killing Cretaceous-Tertiary extinction and several other, even more severe, events. Many scientists now want to add a sixth: the one that humans are causing all over the globe today. But it’s hard to gauge just how severe the current extinction crisis is, compared with others in Earth’s sometimes tumultuous history. Modern extinctions are documented, sometimes in real time. But the Big Five are measured using only the fossil record, a history of those species that were buried and preserved by sediments over time.

That’s why Roy Plotnick, a paleontologist at the University of Illinois, Chicago, and lead author of the study, thinks about far-flung scenarios involving future paleontologists. “We really need to look at modern day extinctions as if they were in the fossil record already, in order to make a comparison,” he says. So he and his colleagues searched fossil databases for modern mammal species—both those threatened by extinction and those that aren’t—to see how many modern extinctions would be detectable by relying only on fossils.

Which of the following is not a reason that nonnative species are reared outside their native ecosystems?
a. They are commercially important.
b. They are used to replace native species.
C. They are used for restocking programs.
d. None of the above

Answers

Answer:

D

Explanation:

All of the given reasons are reasons that nonnative species are reared outside their native ecosystems. The correct option is D.

What are nonnative species?

Non-native species are animals, plants, and other organisms that do not develop natively in a region but are instead introduced through intentional or unintentional human activity.

Non-native species, unlike invasive species, do not necessarily threaten or threaten the existence of other species within the ecosystem.

Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.

Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.

They are employed in restocking efforts, to replace native species, and for commercial purposes.

Thus, the correct option is D.
