You just read an article on the Endosymbiotic Theory. Based on what you read, what is the importance of the Endosymbiotic Theory? its asking for a paragraph pls help!!
Answer:
The endosymbiotic theory which is also sometimes referred to as symbiogenesis states that all the organelles of the eukaryotic cells are prokaryotic cells that tends to live in a much larger host. This theory is important because it does explains how the eukaryotic cells are able to obtain the needed nourishment that is believed to be replenished by the prokaryotic cells.
Explanation:
The endosymbiotic theory provides the foundational bases of the cellular biology field and it enables to understand the evolution of eukaryotic cells.
In a similar manner to the evolutionary theory, endosymbiotic biology is fundamental to understand the evolution of eukaryotic cells.The endosymbiotic theory states that eukaryotic cells evolved by a symbiotic (positive) relationship among a primitive eukaryotic cell and prokaryotic cells. Mitochondria and chloroplasts are organelles that evolved from this cooperation.This theory allows us to understand several features of mitochondria and chloroplasts:Both chloroplasts and mitochondria have their own genetic material (DNA).Chloroplasts and mitochondria have bacterial-like ribosomes, which are responsible for protein synthesis.
In conclusion, the endosymbiotic theory provides the foundational bases of the cellular biology field and it enables to understand the evolution of eukaryotic cells.

what effect would the enzyme have on the amount of product made in 3 seconds?
Answer: I believe it should be increase. If that doesn’t work, let me know and I’ll correct it.
Explanation:
The effect that an enzyme would have on the amount of product made with time would be to increase it.
Basically, what enzyme does is to the lower energy barrier that reactants need to cross in order to get to products - the activation energy.
The similitude of using enzyme in a reaction is like using a shorter route to get to a destination. You gain time as compared to someone that used a longer route. Hence, your rate of reaction is increased.

What is the main cause of an earthquake?
O force of gravity
O the shaking of the ground
stress caused by plate movement
waves that ripple from the epicenter
Answer:
stress caused by plate movement
Stress caused by plate movement is the main cause of an earthquake. So, the correct option is C.
What is an earthquake?A abrupt discharge of energy in the Earth's earth's crust that results in seismic waves causes an earthquake, which is the shaking of the planet's surface.
Sudden movement along Earth's fault lines causes earthquakes. The motion releases "elastic strain" energy that has been accumulated in the form of seismic waves, which travel through the Earth and cause the earth to tremble.
The primary cause of an earthquake is stress brought on by plate movement. Buildings, dams, etc. can sustain significant damage as a result of earthquakes. They might also bring about tsunamis, land slides, floods, and fatalities. A disturbance deep within the earth's crust is the reason behind it.
Therefore, the correct option is C.

A population of ground squirrels lives in underground burrows several miles from an ocean shore. If a hurricane strikes the shore, which effect of the hurricane would probably do the most damage to the squirrel population?
Answer:
flooding
Explanation:
The hurricane brings in enormous amounts of rainfall with it, often resulting in flooding. The ground squirrels in this scenario live relatively close to the ocean shore. They live in burrows, spending big portion of their time in them, as well as having their young ones sheltered in them. The heavy rainfall and the flooding of the area will result in filling the burrows with water. The damage for the population of ground squirrels will be enormous, with their young ones all drowning for sure, and the majority of the adults getting drowned as well, or maybe even all of them.

why do sperm cells need energy?
Sperm cells need energy primarily to move towards and fertilize the egg. This energy is provided by ATP, produced by mitochondria densely packed in the sperm's midpiece. Sperm's functionality and survival depend on this energy, especially during the journey within the female reproductive tract.
Explanation:Sperm cells require energy for several reasons. As highly specialized cells, they are designed to travel a significant distance to reach and fertilize an egg. The midpiece of a sperm is densely packed with mitochondria, organelles known as the powerhouses of the cell, which produce adenosine triphosphate (ATP) — the energy currency of the cell. This energy is crucial for the motion of the sperm’s tail, a long flagellum, allowing it to propel itself forward effectively.
Considering that sperms are minuscule, and so many are produced daily, the speed at which they must move to reach the oocyte is comparable to a human walking briskly. This is a remarkable feat and demands vast amounts of ATP. Additionally, during capacitation, fluids in the female reproductive tract further prepare the sperm for fertilization, which also requires energy.
The behaviorist B.F skinner was a __ when it came to explaining how children learn language
Answer: nurturist
Explanation:
The American psychologist and behaviorist Burroughs Frederick Skinner ( 1904 – 1990) was a Harvard Professor of Psychology. He is considered the pioneer of modern behaviorism. He explained in his book “Behavior of Organisms “ how environmental variables control behavior. He believed that parents’ nurturing shape the child’s language behavior.
Final answer:
B.F. Skinner, a behaviorist, believed children learn language through reinforcement and feedback, but his view was challenged by Noam Chomsky who proposed an innate capacity for language. Today, language acquisition is understood as an interplay of nature and nurture, combining Skinner's behavioral perspective with innate elements suggested by Chomsky.
Explanation:
The behaviorist B.F. Skinner was a proponent of the idea that children learn language through the process of reinforcement and feedback. This perspective posits that behavioral responses, including language, are shaped by environmental stimuli and consequences, such as rewards or punishments. For example, when a child uses a word like cookie, they are met with reinforcement if they receive a cookie or punishment if they are denied. Skinner saw no fundamental difference between verbal behavior, like asking for a cookie, and non-verbal actions, like reaching for one. Skinner's analysis of language suggests that all complex verbal behavior develops from simple beginnings and is then shaped into its more abstract forms, in the same way as any other behavior.
However, Skinner's view on language acquisition was challenged by the linguist Noam Chomsky, who introduced the idea of an innate language acquisition device (LAD) that humans are born with, suggesting that there is an inherent capacity for language learning. Current researchers generally believe that language learning is a combination of innate abilities and environmental influences, a view that combines elements from both Skinner and Chomsky's theories. Consequently, while Skinner's approaches were influential, they are now seen as part of a larger framework that includes biological and cognitive factors.

Eukaryotes, found in the domain Eukarya, have a nucleus and other membrane-bound organelles whereas organisms in the domain Archaea do not. Archaea instead are prokaryotes with no nucleus or membrane-bound organelles.
Explanation:Organisms in the domain Eukarya are different from those in the domain Archaea in several ways, most notably in their cellular structure. The key distinguishing factor is that Eukaryotic cells, found in Eukarya, have a nucleus that contains their DNA and have other distinct membrane-bound organelles such as mitochondria and Golgi bodies. This is option D: Eukaryotes have organelles in membranes.
In contrast, organisms in the domain Archaea don't have these features. They are prokaryotes, meaning their cells do not contain a nucleus or other membrane-bound organelles. Their DNA is found in the cytoplasm rather than a membrane-bound nucleus.
It is also important to note that while some eukaryotes do have cell walls (like plants and fungi), not all eukaryotes do (animals, for instance). By contrast, all archaea have a cell wall, but it's made up of different material than the cell walls in Eukarya.

2. If 28% of the bases in a DNA strand are guanine, what percentage are thymine?
3. DNA replication is semi-conservative. What does this mean?
4. Match the DNA replication enzyme with Its correct function:
1.__ Helicase
2.__ primase
3.__ DNA polymerase
a. Adds new DNA nucleotides
B. Unwinds the DNA strand
C. Add an RNA primer to signal where replication should begin
Answer:
2) According to Erwin Chargaff's rule:
* Purine adenine is equimolar with pyrimidine thymine
* Purine guanine is equimolar with pyrimidine cytosine
i.e. A = T & G = C
So, If G = 28% then C = 28%
Total bases = 100%
A + T + G + C = 100%
2T + 2G = 100%
2T + 56% = 100%
2T = 100% - 56%
2T = 44%
T = 22%
Percentage of thymine = 22%
3) Watson and Crick proposed a scheme for DNA replication that suggest that the two stands of DNA would separate and act as template for the synthesis of complementary strands. After the completion of replication, each DNA molecule would have one parental and one newly synthesized strand. This scheme was termed as semi-conservative DNA replication.
4) 1. Helicase - B. Unwinds the DNA strand
2. Primase - C. Add an RNA primer to signal where replication should begin
3. DNA polymerase - A. Adds new DNA nucleotides

How are the different types of Spectra created?
Different types of spectra are created through processes like emission, absorption, and continuous radiation.
Different types of spectra are created based on how light or electromagnetic radiation interacts with matter:
Emission Spectra: Emission spectra are produced when atoms or molecules emit light as electrons transition from higher to lower energy levels. When an external energy source, such as heat or electricity, excites the electrons within an atom or molecule, they move to higher energy levels. As they return to their ground states, they release energy in the form of specific wavelengths of light. Each element or compound has a unique set of emission lines or spectral lines, allowing scientists to identify the composition of substances and their energy levels.
Absorption Spectra: Absorption spectra are generated when matter absorbs specific wavelengths of light from a continuous spectrum. When light passes through a medium, such as a gas or a liquid, atoms or molecules within that medium can absorb photons with energies that match the energy differences between their electron energy levels. As a result, dark lines or bands, known as absorption lines, appear in the spectrum where light has been absorbed. Absorption spectra help identify the elements or compounds present in a sample and provide information about their energy levels.
