How are elements in the same period in the periodic table alike?
A. They have the same atomic number.
B. They have the same number of electron shells.
C. They have similar chemical properties.
D. They have the same atomic mass.

Answers

Answer 1

Answer:

C

Explanation:

Answer 2

The elements in the same period in the periodic table alike and they  have similar chemical properties. Thus, option C is correct.

What is Groups and Periods in Periodic Table ?

In periodic table there are 18 vertical column which is called groups which are arranged from left to right in the periodic table. In periodic table there are 7 horizontal rows which is called periods.

Elements in the same family or group have a similar chemical properties because they have the same number of valence electrons. In group one all the alkali metals have one valence electrons in the outermost shell.

Thus from the above conclusion we can say that Elements in the same family have a similar chemical properties because they have the same number of valence electrons this statement is true about elements on a periodic table in the same group.

Therefore, The elements in the same period in the periodic table alike and they  have similar chemical properties. Thus, option C is correct.

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.

The diffusion of a substance into or out of a cell requires

Answers

Answer:

Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.

Explanation:

The diffusion of a substance into or out of a cell requires a process called diffusion, by which the molecules pass out through the plasma membrane.

What is diffusion?

Diffusion is a key mechanism for material transfer within cells and for the passage of critical tiny molecules across the cell membrane. This process controls the exchange of gases in the gills and lungs. All cells release carbon dioxide as a byproduct of biological metabolism.

There are two processes by which the molecules pass through a semi-permeable membrane. The processes are osmosis and diffusion. When the material transfer from low concentration to higher concentration.

Thus, diffusion is the process by which molecules travel through the plasma membrane to allow material to enter or exit a cell.

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.

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

Answers

Answer:

4 valence electrons

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).

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.

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.
