Hubble discovered that galaxies are all moving away from each other at fantastic speeds. What was his evidence for this discovery?
Answer:
The plot of the distance of galaxies and their red shifts.
Explanation:
Edwin Hubble was an astronomer and the founder of modern cosmology.
He discovered that galaxies are all moving away at fantastic speed by plotting the distance of eighteen galaxies against their red shifts.
In astronomy, if galaxies move towards the earth, they shift towards the blue end of the spectrum and if they move away from the earth, they shift towards the red end of the spectrum. From his plot, galaxies were moving away from the earth at a rate directly proportional to their distance from the earth. From his calculation, Hubble noted that the greater the red shift, the farther away the galaxy is from the earth, the farther away they are moving from the earth and the faster away they are from each other.
This formed the basis of Hubbles Law.

adenine. What else can be inferred based on this data? Select ALL that apply.
A) The percentage of cytosine is 29%.
B) The percentage of adenine is 21% for all organisms.
C) The percentage of thymine in the organism is also 21%.
D) The percentage of guanine in the organism is also 21%.
E) The percentage for cytosine in the organism is also 21%.
Answer:
A and C
Explanation:
I did the USA tp and got a 100 so you can trust me
If the results showed that 21% of the nucleotides contained adenine, then the percentage of cytosine is 29% and the percentage of thymine in the organism is also 21% (Options A and C).
DNA is a double helix molecule composed of two long chains of nucleotides.
In DNA, there are four types of nucleotides, each containing a different nitrogenous base: adenine, guanine, thymine and cytosine.
According to the base pair rules, adenine always pairs with thymine, whereas guanine pairs with cytosine.
In consequence, the percentage of adenine is equal to thymine, whereas the remining percentage is equal to the guanine + cytocine (29 + 29 = 58 >> 58 + 21 + 21 = 100).
In conclusion, if the results showed that 21% of the nucleotides contained adenine, then the percentage of cytosine is 29% and the percentage of thymine in the organism is also 21% (Options A and C).

Biologists refer to the number of chromosomes with an "#n". For example, 1n for one copy of chromosomes and 2n for two copies. How else can this be expressed?
Answer:
haploid/diploid
Explanation:
The number of chromosomes can also be expressed as haploid or diploid, instead of 1n for one copy and 2n for two copies.
The haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms while the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms.
So, in other words: n = haploid and 2n - diploid.

how is the structure of a nerve cell specialised to carry out its functions
Answer:
A typical neuron consists of a cell body (soma), dendrites, and a single axon. The soma is usually compact. The axon and dendrites are filaments that extrude from it. Dendrites typically branch profusely and extend a few hundred micrometers from the soma. The axon leaves the soma at a swelling called the axon hillock (the axon hillock also has the greatest density of voltage-dependent sodium channels. This makes it the most easily excited part of the neuron and the spike initiation zone for the axon) and it branches but usually maintains a constant diameter. At the farthest tip of the axon's branches are axon terminals, where the neuron can transmit a signal across the synapse to another cell.
In general, dendrites receive the electrical signal from other neurons, and this signal is transmitted over long distances from the axon.
Like all animal cells, the cell body of every neuron is enclosed by a plasma membrane, a bilayer of lipid molecules with many types of protein structures embedded in it. A lipid bilayer is a powerful electrical insulator, but in neurons, many of the protein structures embedded in the membrane are electrically active. These include ion channels that permit electrically charged ions to flow across the membrane and ion pumps that chemically transport ions from one side of the membrane to the other to generate the action potential that generates the electrical signal. They also have a highly developed synthetic apparatus for the production of neurotransmitters

A. Identify two examples of environmental factors that may impact myeloperoxidase activity. Describe how each of the environmental factors would affect the reaction tare of an enzyme.
B. Predict the how researchers can use myeloperoxidase activity as oxidative stress biomarkers in patients with rheumatoid arthritis. Provide reasoning to justify your prediction.
Answer:
So... MPO is most abundantly expressed in neutrophil granulocytes, and produces hypohalous acids to carry out their antimicrobial activity through oxidative damage during the respiratory burst. It requires heme as a cofactor.
Regarding environmental factors ... obviously the first factor is the presence of an infection and inflammation that cause an increase in the activity and production of MPO. Second, alterations in the MPO gene cause its congenital deficiency which predispose to infections.
Rheumatoid arthritis is an autoimmune and autoinflammatory rheumatoid disease in which significant joint damage is observed. In the joint capsule, inflamed infiltrates are observed composed of neutrophils and lymphocytes. Measurement of MPO levels in the joint cavity could therefore be related to the amount of neutrophils and thus to the extent of the inflammatory damage.
When the respiratory burst occurs, MPO is most abundantly expressed in neutrophil granulocytes, which then create hypohalous acids to carry out their antimicrobial function through oxidative damage.
What is MPO?Regarding environmental causes, the first one is undoubtedly the existence of an infection and inflammation, which elevate MPO activity and production.
Second, changes to the MPO gene result in its congenital deficit, which makes people more susceptible to infections.
Therefore, the amount of neutrophils and, consequently, the severity of the inflammatory response might be connected by the measurement of MPO levels in the joint cavity.
Therefore, When the respiratory burst occurs, MPO is most abundantly expressed in neutrophil granulocytes, which then create hypohalous acids to carry out their antimicrobial function through oxidative damage.

describe the role of insulin in regulating blood sugar levels
Answer:
Insulin helps control blood glucose levels by signaling the liver + muscle fat cells to take glucose from the blood. It then helps the cells to take the glucose to be use for energy, and if the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

Explain the difference between sexual reproduction and asexual reproduction. Explain either an advantage or disadvantage for
each.
In asexual reproduction, reproductive organs aren't used but they're used.
advantage of sexual- A lot of genetic variation. since they have DNA of two parents. they can survive more and adapt more.
disadvantage of asexual- diversity is limited. Since the organism only gets the DNA of one parent, they wouldn't be able to really survive if something happened.They would easily be extinct.

Answer:
Explanation:
The process that accurately describes the transport of substances in the body and production of energy in cells is- The lungs inhale oxygen, which is transported to cells by the circulatory system, where cells use it to create energy.Therefore, the correct option is A.
What is respiration?The process of respiration involves the exchange of gases between the environment and the body. During inhalation, air enters the lungs, and oxygen is diffused across the lung tissue and into the bloodstream.
The oxygen-rich blood is then pumped by the heart to the cells throughout the body via the circulatory system. In the cells, the oxygen is used in a process called cellular respiration to produce energy in the form of ATP, which powers cellular functions.
Carbon dioxide, a waste product of cellular respiration, is then transported back to the lungs via the circulatory system and exhaled during exhalation.Therefore, the correct option is A.

In at least one paragraph explain your own stance in the debate between nature and nurture. Describe this debate and use evidence from the class or your
life to support your own beliefs about it. Your paragraph must be a minimum of five complete sentences with correct grammar, spelling, and punctuation
Answer:
There are specific things that us humans experience that are caused by nature and by nurture, but there are also things that they work together on as well. I believe that gender and gender expression is fueled by both nature and nurture. An experiment was conducted in England with toddlers and adults. The adults were to watch over the toddlers and play with them. What the adults didn't know is the toddlers were dressed as the opposite sex. A little girl dressed as a male was handed "boys toys" and a boy dressed as a female was handed "girls toys". But the scientist went even further with her research and went to a zoo. Chimpanzees are our closest relatives and were the target group for the experiment. Different gendered toys were placed about and one by one monkeys began to play with the twos. However, the male chimps played with the "boys toys" and the female with the "girls toys". So it was proven quickly that while it may seem like more nurture than nature, nature does play a role in gender expression.
