The graph shows the changes in the number of animal fauna's living on earth overtime in how the fauna's were affected by different extinction events which statement is correct about the changes in fauna's during one of these five major events
A) The event at the end of the Devonian resulted in the increase in the number of Cambrian fauna’s
B) The event at the end of the Cretaceous resulted in a increase in the number of Paleozoic fauna’s
C) The event at the end of the Triassic Resulted in the extinction of fewer fauna’s then in any other period
D) The event at the end of Cretaceous resulted in the Extinction of more fauna’s then in any other period
Answer: C) The event at the end of the Triassic Resulted in the extinction of fewer fauna’s then in any other period
Explanation:
Looking at the graph, the event at the end of the Triassic resulted in the smallest dip in the amount of fauna in the graph. This means that this event resulted in the extinction of fewer faunas than any of the other five major events.
Option A is wrong as the event at the end of the Devonian decreased the number of Cambrian fauna.
Option B is wrong as the event at the end of the Cretaceous resulted in a decrease in the Paleozoic fauna.
Option D is wrong because the event that resulted in the Extinction of more fauna’s then in any other period was the event at the end of the Permian.

What was Rudolf Virchow’s contribution to the cell theory?
He concluded that all cells come from preexisting cells.
He concluded that cells are the basic units of structure and function of all living things.
He concluded that all organisms are composed of cells.
He concluded that all cells are similar in composition and metabolic activities.
Answer:
He concluded that all cells come from preexisting cells.
Explanation:
Rudolf Virchow was a German scientist experienced in many fields, including medicine, biology, anthropology, and prehistory. He is especially noted for his contribution to the cell theory. He discovered that all cells come from preexisting cells, which made it clear that diseases develop at the cellular level. This means that Virchow was the one to discover that cancer cells originate from healthy cells. All of this allowed scientists to diagnose diseases more accurately and efficiently.
Rudolf Virchow's contribution to the cell theory is that A) he concluded that all cells come from preexisting cells. This concept is known as cell division or cell reproduction.
Virchow observed that cells arise through the division of preexisting cells, suggesting that cells are the fundamental units of life and that new cells are generated from preexisting ones. This principle, often summarized as "omnis cellula e cellula" or "every cell from a cell," is a crucial component of the modern cell theory, which states that cells are the basic structural and functional units of all living organisms.
Therefore, the correct answer is A) he concluded that all cells come from preexisting cells.

What are the different states of matter?
Matter is defined as anything that occupies space and there are three states of matter solid, liquid, and gas. In solid the atoms are closely packed and there is no intermolecular space is found between two atoms. In liquid the atoms are placed at gap and the liquid has more inter molecular space as compare to solid and the last state it gas and it has large inter molecular space.
Solid are the type of material which are compact in shape and fix size or dimension. They are incompressible in nature. Liquid are the type of material which doesn't have fix shape and size . They are incompressible in nature. Gas are the type of material which doesn't have shape and size . They are generally compressible in nature.
Therefore, The arrow in the diagram represents the changes of state between solid, liquid, and gas. Thus, option A is correct.

Why might sand on beaches in Hawaii be different colors even though the sand all formed from igneous rock?
Answer:
n Hawaii you can find black sand beaches, because the sand comes from eroded basalt - lava from the volcanoes. ... That sand is made of olivine, an igneous rock that is rare on the surface of the earth because it breaks down up here, and is stable inside the earth (where the pressure is higher and the temperature hotter.)

Answer:
cats i think
Explanation:
U and V, W and X and Y and Z are most closely related to the ancestral species in the phylogenetic species.
What is phylogenetic species?
Phylogenetic species is defined as the concept of a species as an undifferentiated group whose members are descended from a common ancestor, possessing some defined, or derived, combination of traits, Thus, this concept defines a species as a shared and unique group of the Evolutionary History.
Phylogenetic trees of animals usually show the evolution of animal organs in what are called specialized phylogeny examples. A phylogenetic tree is explained for using of depicting the relationship between different organisms.
Thus, U and V, W and X and Y and Z are most closely related to the ancestral species in the phylogenetic species.

In the light dependent reactions light energy is absorbed by the photosytem II and an electron is released. This electron causes a process called photolysis to occur(H20-->2H++2e-+1/2O2). This is how O2 is released in the atmosphere. The electrons resulted from photolyisis enter the electron transport chain. In the electron transport chain using the energy in the elecrtons, hydrogen protons are pumped inside the thylakoid. Those protons accumulate to form an electrochemical gradient. That means the protons need to flow out, and they do through an enzyme called ATP-synthase which turns ADP and inorganic phosphate into ATP and water. In the electron transport chain, the electrons reach Photosystem I where NADP+ is reduced and becomes NADPH.
ATP and NADPH store the energy absorbed in the light dependent reactions. Those two molecules are needed when CO2 is fixated in Calvin's cycle to synthesize glucose.

Rohit read an interesting fact that if diffusion were to move oxygen in our body, it is estimated that it would take 3 years for a molecule of oxygen to reach our toes from our lungs. Then what is the reason that it travels so fast?
Answer:
See the answer below
Explanation:
Oxygen moves fast around the human body due to the fact that there is a transportation system for it. The blood serves as the transporting medium for oxygen. Haemoglobin in the red blood cells picks up the oxygen and delivers them to places where they are needed in the body.

Explanation:
In a DNA molecule, Adenine forms hydrogen bonds with Thymine and Cytosine forms hydrogen bomds with Guanine.
However in mRNA, Thymine becomes Uracil (T => U)
Therefore every A in the DNA sequence becomes U,
every T in the DNA sequence becomes A,
every C in the DNA sequence becomes G,

write one clear sentence using all the words in the set that demonstrates your understanding of their relationship here are the words . Spindle, Microtubules, Centrosome and centriole?
Answer:
Microtubules have shapes like a spindle and are arranged to form centrosome and a cluster of such microtubules form centriole.
Explanation:
Microtubules are seen in eukaryotic cells to give shape and structure to the cells and they form part of the cytoskeleton. They are known to grow long and are dynamic. Centrosomes are known to be main microtubule that are found in animal cells. They are organelles that are made from the arrangement of clusters of microtubules. The centrioles are organized microtubules that actually help to serve as skeletal system of the cell. These centrioles help to determine the locations of the nucleus.
