What do plate tectonics entail?Large rock slabs called tectonic plates that separate the Earth's crust move constantly, changing the topography of the planet. According to the system of ideas behind the plate tectonics theory, the lithosphere, which makes up Earth's outer shell, is divided into many plates that move across the rocky inner layer of the planet above its soft core (mantle).
What constitutes a plate boundary?The line dividing two plates is referred to as a tectonic plate boundary. The tectonic plates are constantly and slowly shifting, but they do so in numerous directions. Some are travelling past each other while others are moving in opposite directions.

According to the primitive earth model which one of the following compounds was not present in the beginning.
A.NH3
B.H2S
C.CO2
D.O2
The Correct answer is Option D.Oxygen
According to Oparin, oxygen was not present in the primitive atmosphere of the Earth.
What is Oxygen?The chemical element with the atomic number 8 and symbol O is called oxygen. It belongs to the periodic table's chalcogen group, is a very reactive nonmetal, and an oxidising agent that easily produces oxides with most elements as well as other compounds. After hydrogen and helium, oxygen is the third most plentiful element in the universe and the most abundant element on Earth. Two atoms of the element combine to generate dioxygen, an odourless and colourless diatomic gas with the formula O 2 at standard pressure and temperature.
According to researchers at MIT, the Great Oxygenation Event (GOE), which is thought to have started as early as 2.33 billion years ago, was the beginning of oxygen's ongoing presence in the atmosphere.
Oxygen in Primitive EarthLouis Pasteur wrote about his research in 1864, demonstrating that microbial life could not have developed spontaneously in the absence of preceding life. This work is regarded as a milestone in modern science as it resolved a long-running debate regarding spontaneous generation.
The concept of spontaneous genesis holds that live things could appear miraculously from inanimate matter.
But Pasteur's findings presented evolutionary biologists with a fresh conundrum: if life could only develop from life, how did living things first originate on the planet?
The solution was presented in the 1920s by A.I. Oparin of Russia and J.B.S. Haldane of England, who independently made compelling cases that the origin of life could be explained by a lengthy and gradual process of chemical evolution rather than by the rapid spontaneous generation of complete organisms in a matter of weeks.
Elements primitive earthAn atmosphere developed when Earth cooled, primarily from gases released by volcanoes. It contained methane, hydrogen sulphide, and ten to 200 times as much carbon dioxide as the atmosphere we are surrounded by today. The Earth's surface began to cool and solidify after roughly 500 million years, allowing water to accumulate there.

Group of answer choices interact strongly with the molecules they transport undergo a conformation change with every solute they transport can only mediate passive transport form pores that are always open are always controlled by voltage
In contrast to transporters, ion channels in cellular membranes can only mediate passive transport form pores.
Only in order to open a membrane pore that enables a certain ion into the membrane do channel proteins undergo a conformation in the membrane. In contrast to carrier proteins, the ion will only move along its concentration gradient. It has been discovered that all membrane transport proteins that have been in-depth study are multipass transmembrane proteins, meaning that their transporters chains repeatedly pass through the lipid bilayer. These proteins allow certain hydrophilic solutes to traverse the membrane without coming into touch with the hydrophobic interior of the lipid bilayer by establishing a continuous protein pathway across the membrane.

Arrange the following terms into the order in which a compound must pass through to move from plasma to CSF: -capillary endothelium
-pericyte
-astrocyte
-extracellular matrix
When a compound passes from the plasma to the CSF, it first goes through the extracellular matrix, then the astrocytes, then pericytes, then the capillary endothelium and finally to the CSF.
Cerebrospinal fluid or the CSF is a clear and colorless fluid which is found in the tissues which are present around the brain and the spinal cord. The blood brain barrier or the BBB is the network which consists of tissues and blood vessels which perform the function of keeping the harmful substances away from the brain.
When a particular compound passes from the plasma to CSF, it first has to pass through the extracellular matrix of the ECM. From the ECM, it goes to the astrocytes and then to the pericytes. The compound then passes to the capillary endothelium from where it finally reaches the CSF.

What do you expect when the cell wall of a plant cell is removed by a certain way, then put in distilled water? a)The cell takes a longer time to swell. b)The proteins that are present in the cytoplasm exit through the cell membrane. c) The cell shrinks. d) The cell bursts. why is the correct answer (d)
The cell bursts when the cell wall of a plant cell is removed by a certain way, then put in distilled water because the cell wall is removed, the cell would get wet, which would cause it to burst..
How do plant cells react to exposure to distilled water?Putting a plant cell in distilled water causes it to become turgid. This is due to a process called osmosis, which causes the plant cell's cytoplasm to swell up and firmly press up against the cell wall as it absorbs water from the hypotonic distilled water.
Cell walls stop excessive endosmosis from happening when water enters the cell, which also prevents plant cells from bursting. If the cell wall were to be broken, water would enter the space and the cell would eventually burst.

Explain why the energy available at the top layer of the pyramid is a small percentage of the energy present at the bottom of the pyramid: *
The energy available at the top of the pyramid is a small percentage of the energy present at the bottom of the pyramid because of the process of energy transfer.
As energy flows up the pyramid, each level of the pyramid takes in energy from the level below and uses it to produce its own energy. This energy transfer is not 100% efficient, so some energy is lost at each level. By the time the energy reaches the top of the pyramid, the amount of available energy is greatly reduced.
Additionally, the organisms at the top of the pyramid have to use energy to stay alive and move around, so there is even less energy left to transfer to the next level. This is why the energy available at the top of the pyramid is so much smaller than the energy present at the bottom.

Answer: A. DNA is transcribed into RNA, which is translated into protein
Explanation:
The process of gene expression is the information from DNA is transcribed into RNA, then this RNA is translated into protein.
What is gene expression?Gene expression is the process of directing protein synthesis by utilizing the genetic information encoded in genes (DNA). Gene expression enables organisms to develop various cell types and adapt to internal and external influences.
The process of gene excretion takes place in the cell nucleus and cytoplasm and is divided into two stages: transcription and translation.
DNA is employed in the transcription process to create copies in the form of mRNA. While translation is the process by which individual polypeptides are synthesized in the ribosome. Protein can be made up of one or more polypeptides.
Therefore, the information from DNA is transcribed into RNA, which is then translated into protein during the gene expression process.

Explain what will happen if there are not enough resources to support the individuals in a species.
This experiment tested natural selection. What could be another possible mechanism of evolution for the rabbits to evolve? Be specific.
Due to their ability to blend in with their surroundings, White Rabbits are more likely to survive than Brown Rabbits.
What is natural selection?The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways.
Resources are necessary for a species' growth and survival, therefore if there aren't enough of them to support each member of the species, they can't reproduce.
The adaptations that could affect a person's likelihood of survival are sharp teeth, rough skin, or claws to fight off predators. These adaptations stop them from killing.
As a result, we can draw the conclusion that white rabbits are more likely to survive than brown ones do because they can blend in better with the environment's light colours.
Thus, this can be the summary of the given scenario.
