How have human activities effected the air in earth’s atmosphere?
Answer:
Human activities have had a negative impact on Earth's atmosphere.
Explanation:
Human activities, since the Industrial Revolution, have gradually been having more and more influence on Earth's atmosphere. As more and more the economies have developed, the bigger and bigger the output of gases into the atmosphere. The gases that are released into the atmosphere are mostly greenhouse gases, but there are also some that are highly toxic.
This has contributed to a sharp increase in CO2 levels in the atmosphere, which is speeding up the process of global warming, and that can have devastating consequences for life on Earth. Also, some of these gases managed to cause huge damage to the ozone layer, the layer that protects us from UV radiation, and if the ozone is gone, every complex organism will be gone as well.

Living things obtain matter from their environment and release waste back into it. This matter moves in a cycle. Plants use air, water, nutrients, and sunlight to make food and grow. Some animals eat the plants and use their matter to grow. When those animals die, decomposers will grow using the matter from the animals' bodies. The decomposers release this digested matter back into the air and soil. The matter in an ecosystem is recycled. Gases are a type of matter that moves through an ecosystem. For example, oxygen and carbon dioxide are cycled between organisms and the air. The producer in the diagram takes carbon dioxide from the air. It uses this gas and water to make sugar, releasing oxygen as waste. Then the consumer breathes in the oxygen and uses it in its body. It also eats the producer for food, represented as carbon in the diagram. The decomposer takes oxygen from the air and food from the consumer or producer. The consumer and decomposer make carbon dioxide, putting it into the air. When producers use it again, the matter is recycled. Describe in words how carbon and oxygen move through an ecosystem. (my little bro needs help and I am to lazy to do it)
Answer:
"living things obtain matter from their environment and release waste back". plants use carbon dioxide, then let out oxygen for us to use. When animals die, decomposers release the digested matter back into the air and soil. Different types of gases move throughout a ecosystem and is recycled between organisms and air. (again going back to the air recycled between a plant and a human).
Answer:
the decomposers release carbon dioxide that help plans grow then they can do photosynthesis then the oxygen is given to animals then they die then decompose and that's a cycle
Explanation:
Why is it important to reduce the number of chromosomes in half when forming gametes for sexual reproduction?
a) The offspring will have the correct number of chromosomes when sperm and egg are joined.
b)Gametes have single function which requires less DNA to preform the function compared to somatic cells.
c)A reduction in the number of chromosomes reduces the chances for mutations that would affect the offspring.
d)The chromosomes in gametes are already replicated strands of DNA which returns the number of chromosomes to the original amount.
Answer:
B.
Explanation:
It is important to reduce the number of chromosomes in half when forming gametes for reproduction because offspring will have the correct number of chromosomes when sperm and egg are joined.
WHAT ARE GAMETES:Gametes are cells produced for the purpose of reproduction. Gametes are produced as a result of meiosis, which reduces the chromosome number by half. Gametes include sperm cells and egg cells, which fuse together to form zygote. The zygote develops into a new organism.Therefore, reduction is necessary in order to have the correct number of chromosomes when sperm and egg are joined.

Additionally, Control: Pikas within their tolerance range of temperature and Constants: Other environmental factors, habitat conditions, and population of pikas.
What are the independent and dependent variables in this experiment?In this experiment, the independent variable is the temperature, specifically the range of temperature. The researcher will manipulate and observe how different temperature ranges affect the distribution of pikas.
The dependent variable is the distribution of pikas. It refers to the geographical or spatial range in which pikas are found. The researcher will measure and analyze how the distribution of pikas changes in response to different temperature ranges.
What is control and the constants to ensure test validity in this experiment?To ensure test validity, a control group of pikas within their tolerance range of temperature needs to be included. This group will experience temperatures within the range they can tolerate, providing a baseline for comparison. By comparing the distribution of pikas in different temperature ranges to the control group, the researcher can determine the impact of temperature on their distribution.
To maintain validity, other environmental factors such as altitude, precipitation, vegetation, and habitat conditions should be kept constant across the experimental groups. Additionally, the population of pikas being studied should be consistent, without any significant changes in population size or genetic composition throughout the experiment. These constants help isolate the effect of temperature on pika distribution and minimize confounding variables.

Replication of DNA is one of the genetical processes in organisms. How is DNA replicated?
Briefly describe the mechanism of semi-conservative method of replication that forms daughter DNAs with necessary diagrams.
[2+4+2]
DNA replication is the duplication of the molecule, which occurs during the interphase. This is a semi-conservative process in which different enzymes are needed to grow a new strand complementing the old strand.
What is the eukaryotic DNA replication process?
Eukaryotic DNA replication is the process through which a DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.
DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.
The origin of the replication requires,
The helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated. Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs thymine, and cytosine pairs guanine.DNA strands are antiparallel, and replication occurs only in 5'-3'direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.
Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

Why is water a lubricant— how does this relate to cohesion?
Water is a unique molecule thanks to its chemical properties. Since water has a dipole (negative in the Oxigen side, positive in the Hidrogens) it is able to create weak electrostatic interactions between H -O of diferent water molecules (also called "Hidrogen bridges"). This weak interactions, are scaled in strenght when you consider the total amount of water molecules. Thus, we can conceive water as an "electrostatic mesh", comprised of this electrostatic interactions, which allow lubrication and cohesion between the molecules.

Which of the following occur in a maple tree growing in a temperate climate in response to increasing cold weather? Choose three correct answers.
The three correct answers are:
B. The chlorophyll in the leaves break down, revealing yellow and red pigments that had been masked by the green pigments. This process leads to the beautiful fall foliage colors observed in maple trees. As the weather gets colder, the breakdown of chlorophyll exposes the underlying pigments, creating vibrant red, orange, and yellow leaves.
C. Xylem and phloem fill with ions and organic substances that prevent freezing. In response to increasing cold weather, the tree transports ions and organic compounds into the xylem and phloem. These substances act as antifreeze agents, preventing the freezing of sap and ensuring the circulation of nutrients and water within the tree.
D. Meristems form thick scales to protect next year's buds from cold winter temperatures. The meristems, which are the regions of the tree where new growth occurs, undergo changes in response to the approaching cold weather.

Below are the reduction half reactions for chemolithoautotrophic nitrification, where ammonia is a source of electrons and energy and oxygen is the terminal electron acceptor.
NO2- + 6e- -> NH4+ (+0.34 volts)
O2 + 4e- -> 2H2O (+0.82 volts)
Using the information given, calculate the ΔE for this reaction, balance the full reaction to determine the n, the number of electrons transferred when 440 moles of NH4+ are oxidized. Finally, use the simplified Nernst Equation
ΔG = -nFΔE, where F = 96.5 kJ (mol e- × V)-1
to determine the Gibbs Free energy available to do work!
Report your answer in kJ rounded to two decimal places.
The Gibbs free energy available to do work for the reaction is approximately -15,427.20 kJ, rounded to two decimal places.
To calculate the Gibbs free energy (ΔG) available to do work for the given reaction, we need to use the formula:
ΔG = -nFΔE
where ΔE is the potential difference, n is the number of electrons transferred, and F is the Faraday constant (96.5 kJ/(mol e- × V)).
First, let's calculate the ΔE for the reaction by subtracting the reduction potential of the anode (NH4+ to NO2-) from the reduction potential of the cathode (O2 to H2O):
ΔE = E(cathode) - E(anode)
= (+0.82 V) - (+0.34 V)
= +0.48 V
Next, we need to balance the full reaction to determine the number of electrons transferred (n) when 440 moles of NH4+ are oxidized. The balanced equation is as follows:
8NH4+ + 6O2 -> 8H2O + 6NO3- + 16H+
From the balanced equation, we can see that for every 8 moles of NH4+ oxidized, 6 moles of electrons are transferred.
So, the number of electrons transferred (n) when 440 moles of NH4+ are oxidized can be calculated as:
n = (6 mol e- / 8 mol NH4+) × 440 mol NH4+
= 330 mol e-
Therefore, when 440 moles of NH4+ are oxidized, 330 moles of electrons are transferred.
Now, let's substitute the values into the equation:
ΔG = -nFΔE
= -(330 mol e-) × (96.5 kJ/(mol e- × V)) × (+0.48 V)
Calculating this expression, we find:
ΔG ≈ -15,427.20 kJ
