Answer:
The correct answer is - 35%.
Explanation:
According to the rule of Chargaff the amount of adneine is equalls to thymine and the amount of guanine is equalls to cytosine in DNA. In a double-stranded DNA Adenine pairs with Thymine and cytosine pairs with Guanine.
So, Percentage of Adenine = percentage of Thymine
and, percentage of Cytosine = percentage of guanine
we know, percentage of guanine = 35%
Thus, percentage of Cytosine will be 35% as well.

How do meiosis I and II contribute to genetic variation?
Meiosis I and II contributes to genetic variation by:
Giving each daughter cell one chromosome from the chromatids which remains after Meiosis IMeiosis I and II are both processes of cell differentiation where two cells divide to produce four daughter cells which contain genetic information.
Meiosis I starts with one diploid parent cell and after its division, it gets two haploid daughter cells which have the same amount of chromosome.
Meiosis II makes use of the chromatids that are left after the cell division in Meiosis I as the daughter cells get DNA.

How does slow movement aid sloths in acquiring food?
Answer:
Sloths are so slow moving that algae is able to grow symbiotically in their fur. This algae can be licked out of the sloth's fur to provide it with nourishment.
Explanation:
The slow movement aid sloth in acquiring food, as slow and limited movements need less food and nutrition. It also helps in digesting food and the metabolism also works slowly.
What are sloths?Sloths are arboreal Neotropical mammals that are very slow-moving and are herbivores, they eat leaves and algae, and twigs. They live in evergreen forests and tropical rainforests.
They are so slow that algae grow above their furs, which helps them camouflage between green forests from predators. Because they are quite adept at concealment. They not only live nearly entirely in trees and only venture out if absolutely necessary, but they also harbor algae in their fur that help them blend in.
Therefore, due to their limited and slow movements, sloths require less food and nutrition when foraging for food. Additionally, it aids in food digestion and slows down metabolism.

Why would an airplane flying at 10,000 meters above the ground have more gravitational potential energy than the same airplane flying at 1,000 meters above the ground?
Answer: because the
Explanation: A flying airplane has potential energy has it flies above the ground level. And since the airplane is flying motion is associated with it and thus possesses kinetic energy.
The plane at 10,000 m will have more gravitational potential energy because it is directly proportional to height.
What is gravitational potential energy?
The energy stored by an object as a result of its position is called potential energy.
When an object is at a height, it is able to store gravitational potential energy. This energy is because of the attractive force of gravity acting on the object as a result of its height.
Gravitational potential energy is mainly dependent on two factors. These are - the mass of the object held at a height and the height at which it is held i.e the vertical distance between the object and the earth.
Gravitational potential energy is equal to
P E = m × g × h
Where m is the mass of the object
g is the acceleration due to gravity
h is the height
Therefore, gravitational potential energy is directly proportional to the mass of the object and the height at which it is held.
Since in the above case, we are talking about the same airplane so mass will be common. But at a height of 10,000m gravitational potential energy will be considerably higher compared to at a height of 1000 m.

For example, red flowers and white flowers would breed ____________ flowers unless ____________ in the genetic material existed.
Answer:
For example, red flowers and white flowers would breed pink flowers unless instability in the genetic material existed.
Note: The complete answers are provided in the explanation below
Explanation:
Prior to Mendel's work on genetics using pea plants hypotheses were proposed to explain heredity.
One of these hypotheses supported the blending concept of inheritance.
Most breeders acknowledged that both sexes contributed equally to offspring traits to create offspring with intermediate traits.
For example, red flowers and white flowers would breed pink flowers unless instability in the genetic material existed.
However, this model of inheritance didn't account for the presence of non-intermediate traits that exist in populations
how many years would it take a radio signal from the exoplanet wolf 359 to reach earth? Wolf is 7.9 light years from earth.
Answer:
Radio waves move at the speed of light which is aproximately 300,000 km per second or 3.8*10^8 m/s
1 ly = 9.461*10^15 m
Then
7.9 light-years = 7.4*10^16 m
By, velocity = distance/ time
time = distance/time
t = 7.4*10^16/3.8*10^8
= 1.9473684*10^24 seconds
Converting seconds to years (1 year = 31536000 seconds)
1.9473684*10^24/ 31536000 years
=6.17096989 ×10^16 years
PLEASE HELP! Predict one potential explanation for why the number of H+ passing through ATP synthase decreases in this scenario.
In eukaryotes, aerobic respiration relies on a gradient where H+ are concentrated between the inner and outer mitochondrial membranes. This gradient is used as an energy source when H+ flow through the channel protein, ATP synthase. If the mitochondrial membrane is suddenly exposed to heat, the number of H+ flowing through ATP synthase decreases.

Imagine you are a carbon atom. Describe your journey through the carbon cycle be sure to include and explain the key processes in the cycle
(include the following in your answer)
Describe how the carbon atoms in CO2 absorbed via plant photosynthesis provide the carbon atoms for all of the new carbon compounds a plant produces and uses to build its cells and tissues and to burn for energy.
Explain how carbon compounds are transformed in five chemical reactions that are critical to the carbon cycle: photosynthesis, cell respiration, decomposition, biosynthesis and combustion.
Explain how carbon moves from one Earth System sphere (neighborhood) to another
Explain how carbon changes as it moves from one part of the carbon cycle to another
Describe where carbon is stored
Answer:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
1. Photosynthesis
Photosynthesis Process
Plants pull in carbon dioxide out of the air through photosynthesis. Even though carbon dioxide makes up less than 1% of the atmosphere, it plays a major role for living things.
With CO2 and H2O in the atmosphere, photosynthesis produces sugars like glucose. This is the plant material that plants synthesize on their own.
If you have the right conditions, this process can repeat for centuries. Not only does photosynthesis pulls carbon dioxide out of the atmosphere, but it’s fuels all living things as a source of energy.
2. Decomposition
Nutrient Cycle
By mostly using sunlight, water and carbon dioxide, plants can grow. In turn, animals consume food for energy using O2 and giving off CO2. Alternatively, they die, decay and decompose repeating for millions of years.
Decomposition is the process of breaking down plants. Over vast periods of time, layers of sediment build on each other. Because of the pressure and heat from within the Earth’s crust, this generates fossil fuels. Much of this happened during the Carboniferous Era.
For example, coal, oil and natural gas (methane) are some of the common fossil fuels. Over the long-term, the decomposition of dead matter generates these fossil fuel products.
Anaerobic decomposition involves bacteria breaking down organic matter such as glucose into CO2 and methane (CH4). The nutrient cycle recycles inorganic and organic material in soil through the process of decomposition. Then, it goes back again through the same process again.
3. Respiration
Cellular Respiration
You and I are both made of carbon. We consume plants. But we also breathe in the air, which has carbon in the form of carbon dioxide.
Animals rely on plants for food, energy and oxygen. Our cells require oxygen to break down the food we consume through cellular respiration.
Once consumed, carbon dioxide is released into the atmosphere because of cell respiration. In turn, this CO2 produced from respiring cells can be used in photosynthesis again.
In other words, the plants use solar energy to break apart that same carbon dioxide in the air. Through photosynthesis, it uses that same carbon for plant material in turn releasing oxygen again.
4. Combustion
Gas Combustion
Our cars use the energy released by burning fossil fuels. And carbon is also a pollutant as carbon dioxide.
We extract fossil fuels, combustion involves burning them to release energy. But a by-product of combustion is that it releases carbon dioxide back into the atmosphere. And too much CO2 increases the greenhouse effect.
And as we deplete our oil reserves adding CO2 into the air daily, this affects the carbon cycle with an imbalance of oxygen and carbon. Carbon dioxide is one of the greenhouse gases contributing to climate change.
But there is a limit for how much fossil fuels we can extract. Over millions of years, phytoplankton resting on the ocean surface photosynthesizes and takes in CO2.
Using sunlight, it creates a molecule called glucose (C6H12O6) and sinks to bottom of the ocean. Humans discovered these fossil fuels beneath the ocean. We started to drill the ancient plankton, which over millions of years ago, became the oil we use today.

2. Tay-Sachs disease is a human genetic abnormality that results in cells accumulating and becoming clogged with very large, complex, undigested lipids. Which cellular organelle must be NONfunctioning in this condition?
a. the rough endoplasmic reticulum
b. the golgi apparatus
c. the lysosome
d. the mitochondrion
Answer:
The correct option for question 1 is
Option A.
permeability to glucose will increase
2. Correct option is C.
The lysosome.
Explanation:
1. increasing the proportion of saturated phospholipids in lipid bilayer will increase the permeability of glucose because normally the phospholipid bilayer is impermeable to most water insoluble substances like glucose, therefore to increase glucose permeability by the membrane saturated phospholipids need to be increase in the bilayer becayse saturated phospholipids tails have no double bonds and they are straight making it permeable to glucose.
2. The cellular organelles non functioning in Tay-Sachs disease is lysosome because lysosome is an organelles found in eukaryotic organisms that contain the digestive enzymes which help to digest food. In the case of Tay-Sachs, her lysosome is not functioning that is why there is accumulation of large complex undigested lipids because the lysosomes is malfunctioning and digestion cannot take place.

Consider the following food chain… Grass, beetles, raccoons, and coyotes live in a forest ecosystem. When a raccoon eats a beetle, the matter that made up the beetle’s body is transferred to the raccoon, and the total amount of matter in the ecosystem…
The total amount of matter in the ecosystem basically 'remains the same. The matter is recycled in the ecosystem, so its total amount is not changed'.
What do you mean by ecosystem?
An ecosystem is a community of living organisms (plants, animals, and microbes) and their physical environment interacting as a system. The complex network of interactions between the living organisms and their environment, including their interactions with one another, is known as an ecosystem.
Matter is a finite resource, meaning that it cannot be created or destroyed. When a raccoon eats a beetle, the matter that makes up the beetle's body is transferred to the raccoon, but it does not leave the ecosystem. The matter is simply being recycled and reused in the ecosystem. This means that the total amount of matter in the ecosystem remains the same, even though the material is being used by different organisms.
