Australia
Africa
Antarctica
Asia
Answer:
Antarctica
Explanation:
Rotifers are multicellular organisms of various shapes. Their length is from 0.1 to 0.5 mm. The process of feeding in rotators is very interesting due to the presence of the so-called "hunting apparatus".
The device consists of cilia, by the movement of which the rotators create a stream of water and thus attract the microorganisms they feed on.

Crustal movements in one location can affect locations far away.What evidence from the text supports this conclusion?A. Steady advancement in technology has allowed geologists to better understand plate tectonics. B. The mantle is made up of elements like oxygen, silicon, and magnesium.C. Geologists mapped the ocean floor and discovered the mid-oceanic ridge.D. Divergent boundaries in the ocean create a chain reaction that pulls plates apart on land
The geologists mapped the ocean floor and discovered the mid-oceanic ridge. The correct option is C.
What is crustal movement?The movement of the plates that make up the Earth's crust is referred to as tectonic shift. The Earth is comprised of a many major plates and several minor plates.
The Earth is constantly undergoing change. The Earth's crust, known as the lithosphere, is made up of 15 to 20 moving tectonic plates.
Very active crustal movements in subduction zones, characterized by uplift and erosion in island arcs and subsidence and sedimentation in ocean trenches, continue indefinitely.
The upward movement of hot rocks from deeper parts of the Earth's crust is unavoidable due to uplift and erosion of the Earth's crust.
Geologists discovered the mid-oceanic ridge after mapping the ocean floor.
Crustal movements generate boundaries that are convergent, divergent, and transformative.
Thus, the correct option is C.

PLEASE HELP WITH SOME BIOLOGY!!
The sodium-potassium ion pump simultaneously transports two different solutes. Is the sodium-potassium ion pump an example of a cotransporter? Justify your answer by explaining the mechanism of the pump.
SERIOUS ANSWERS PLEASE. GOD BLESS
Answer:
The sodium-potassium ion pump does not simultaneously transport sodium and potassium molecules, but alternatively, it is a primary active transport and not a co-transport.
Explanation:
The sodium-potassium ATP-ase pump is considered an active transport mechanism, in charge of transporting sodium (Na⁺) and potassium (K⁺) ions from and to the exterior, in alternative form.
When the pump opening is inside it has a high affinity for Na⁺ ions, which it introduces into the cell. Once Na⁺ is transported, the pump changes its configuration, releases the Na⁺ ions and has its affinity increased by the K⁺, to which it binds and transports to the outside. This implies a primary active transport type.
The cotransport, a secondary active transport, can carry out the transport of molecules and ions simultaneously, since the configuration of the transporting protein allows it. An example of this is the sodium-glucose pump.
The Na⁺-K⁺ ATP-ase pump, being an alternate, non-simultaneous form of transport, is not considered a co-transport.

In fruit flies, curved wings are recessive to straight wings, and ebony body is recessive to gray body. A cross was made between true-breeding flies with curved wings and gray bodies to flies with true-breeding straight wings and ebony bodies. The F1 offspring were then mated to flies with curved wings and ebony bodies to produce an F2 generation.
1. Diagram the genotypes of this cross, starting with the parental generation and ending with the F2 generation.
2. What are the predicted phenotypic ratios of this F2 generation?
3. Suppose the following data were obtained for this F2 generation:
114 curved wings, ebony body
105 curved wings, gray body
111 straight wings, gray body
114 straight wings, ebony body
Conduct a chi-square analysis to determine if the experimental data are consistent with the expected outcome based on Mendel's laws.
Answer:
Population of F2 generation will be formed on 9:3:3:1 ratio.
Explanation:
The predicted phenotypic ratios of F2 generation is 9:3:3:1. Ratio 9 represents straight wings, gray body which are dominant allele, ratio 3 represents hybrid flies having curved wings, gray body, ratio 3 represents hybrid flies having curved wings, ebony body and ratio 1 indicates flies with curved wings, ebony body. The population of F2 generation will be formed on the above ratio.
The study of genes is called genetics.
The correct answer is Population of the F2 generation will be formed on the 9:3:3:1 ratio.
What is a dihybrid cross?When more than two characters are crossed to form a new breed is called a dihybrid cross.

The NADH and FADH2 used by the electron transport chain are normally produced in the mitochondria; however. Select one:
a. NADH is also produced during glycolysis in the cytoplasm.
b. NADH is only produced and used in the mitochondria; FADH2 can be used elsewhere.
c. FADH2 is also produced by the citric acid cycle; NADH is not.
d. FADH2 produced in the mitochondria has more energy than does NADH.
Answer:
The correct answer is option A (NADH is also produced during glycolysis in the cytoplasm).
Explanation:
NADH is NAD + hydrogen, which is among the list of chemicals that produce energy for the body. It's among the vitamins that act as fuel for electrons during cellular respiration. NADH makes more ATP than FADH2 producing water during the electron transport chain.
During the electron transport chain, which is a step in aerobic respiration, both NADH and FADH2 supplies the much-needed H for the formation of ATP.
Glycolysis, which leads to the formation of ATP occurs in the cytoplasm gives energy for metabolism in the cells after is being broken down produces NADH.

Why
will some molecules such as oxygen, carbon dioxide, nitrogen freely
move through the lipid bilayer of the cell membrane? *
O They are hydrophobic.
O They are ions.
O They are small, non-polar.
They are polar
Answer:
Explanation:
Option A they are hydrophobic is the correct answer
These molecules move across the lipid membrane because they are hydrophobic. So the correct option is A.
What is hydrophobic?In both the home and industrial realms, several hydrophobic materials may be discovered. The vast majority of organic molecules, alkanes, oils, fats, and greasy substances are hydrophobic by nature.
Hydrophobic chemicals are used in a variety of processes, such as the chemical separation of polar elements from non-polar ones, the cleanup of oil spills, and the removal of oil from aqueous solutions. It is a well-known fact that when oil or fats are combined with water, two different layers are created that are inimical to one another since water is polar, but fats and grease are non-polar and especially hydrophobic.
Animals and plants both exhibit hydrophobicity as examples. There are hydrophobic coats on the surface of the leaves since many plants are hydrophobic in nature. The coating's main duty is to prevent water and rain from adhering to the leaves, which often stops the flow of nutrients.
The movement of water from roots to leaves determines how quickly nitrites move through plants. Therefore, if the leaf surfaces lack hydrophobicity, the osmosis process and osmotic pressure will be disrupted, which will have a significant impact on how well plants are nourished.
Therefore the correct option is A.

Younger fossils are often morphologically different from older fossils in a lineage. How do paleontologists think the morphological transition happened
Answer:
Paleontologists thinks that the younger fossils are a species that underwent an-agenesis, gradually evolving a new morphology or/and the younger fossils are a new species that branched off the older one, rapidly evolving a new morphology.
Explanation:
Fossils are the safeguarded remains or hints of creatures, plants, and different life forms from an earlier time. Fossils range in age from 10,000 to 3.48 billion years of age. The perception that specific fossils were related with certain stone layers drove nineteenth century geologists to perceive a land timescale. Like surviving life forms, fossils differ in size from minuscule, similar to single-celled microscopic organisms, to monstrous, similar to dinosaurs and trees.
Fossils give strong proof that living beings from the past are not equivalent to those discovered today; fossils show a movement of advancement. Fossils, alongside the similar life systems of present-day life forms, comprise the morphological, or anatomical, record.
By contrasting the life structures of both present day and terminated species, paleontologists can deduce the ancestries of those species. This methodology is best for life forms that had hard body parts, for example, shells, bones or teeth. The subsequent fossil record recounts the account of the past and shows the development of structure more than a great many years.

Why is "dysfunction of the brain" so hard to wrap your head around? How is it different
from, say "dysfunction of the pancreas"?
Answer: I would say it's because there is so much about the brain that we don't know about yet, it's harder for us to understand certain illnesses and dysfunctions because of the sheer complexity of the organ and the role it plays in our own existence. It's easier to understand an organ such as the pancreas because while both fragile and complex, it is not nearly as mysterious as the human brain and doesn't have even nearly the same range of function.

If a DNA molecule has 24% adenine, what is the percentage of guanine in the same DNA molecule?
A. 52%
B. 24 %
C. 48 %
D. 26%
I need help plzz
Answer:
26%
Explanation:
Adenine pairs with thymine.
Guanine pairs with cytosine.
If 24% of the DNA molecule is adenine, that means that there is 24% thymine. This is because they pair together so they have to be equal. That is 48% of the DNA molecule. To find the percentage of guanine, we need to minus 48% from the total 100%.
100 - 48 = 52
Then divide by 2 because you have guanine AND cytosine.
52/2 = 26
Therefore, your final answer is 26% of guanine is in the DNA molecule.
