Answers
The answers are Polar zones - coldest zone; temperate zones-moderate temperature zone; and tropical zones - hottest zone
Explanation:
One factor that influences the temperature is the latitude or location of places north or south from the Equator line (imaginary line that divides the Earth in North and South). In this way, zones in the equator line and near it that belong to tropical zones are the hottest, this is because due to the tilt of Earth they are more directly exposed to sunlight. On the contrary, zones in the poles that are far from the Equator have low temperatures and are the coldest zones on Earth because they are not highly exposed to sunlight. Additionally, temperate zones that are placed between the equator, and the poles have moderate temperature that is not as cold as in the poles or as hot as in the tropical zones.

Since Jerry's accident, he has had no sensations in his injured leg. Based on the functional classifications of neurons, what type of neuron suffered damage
Answers
Answer:
Sensory neuron
Explanation:
There are the major classifications to neurons - sensory, motor and inter relay.
All these neurons helps in the relay of signals from the environment to the CNS where these signals are interrupted and actions are Carrie out. The sensory neurons begins this order and help in the relay of sensation from external stimuli.
Thus since Jerry has no sensations in his injured legs, it means he is unable to detect or feel external stimuli/or there is a damage to the sensory neurons in the region of his legs which prevents the relay of information to the CNS.

During the process of mountain building, earthquakes sometimes occur along continental-continental converge
boundaries. Which statement best describes the motion of the plates along these boundaries that causes the
earthquakes?
Answers
Answer:
The main cause of earthquake is the motion of tectonic plates which occurs due to friction.
Explanation:
The tectonic plates moves slowly inside the earth crust but the edges of these plates stuck with each other due to friction that occurs during their contact. When these two plates detached from each other, the force of friction converts in a form of wave energy which can be observed in the form of earthquake. Divergent, convergent, and transform are the three types of plate boundaries which are responsible for earthquake.

Explanation:
This element is a gas that is found in both nucleic acids and in amino acids, important building blocks of life. What is it? A. Nitrogen B. Sulfur C. Oxygen D. Carbon My answer is: A) Nitrogen
Answers
Answer:
Yes, your answer, nitrogen, is correct (the most appropriate option). However, oxygen is also a correct option.
Explanation:
Nitrogen exists on its own as a diatomic gas. However, it exists as organic nitrogen in nucleic acids such as DNA and RNA (as part of their nitrogenous bases) and in the amino (--[tex]NH_{2}[/tex]) group of amino acids.
Do note that a case can also be made for oxygen as a right option: like nitrogen, it exists as a diatomic gas and can be found in both nucleic acids and in the carboxylic group of amino acids.
Sulfur is not an appropriate option as nitrogenous bases (and nucleic acids) to the best of my knowledge do not contain sulphur although some amino acids like cysteine do.
Carbon is not also an appropriate option because elemental carbon does not exist in gaseous form even though it can be found in both nucleic acids and amino acids.

Which is a function performed by the central nervous system ( CNS) select all that apply
Answers
Answer:
The Central Nervous system is made up of the brain,the control units,and the spinal cord ,the network of nerves ,which feed the brain with sensory information for processing.The entire CNS is lined by a constantly circulating fluid called the Cerebrospinal Fluid.(CSF).
Together with the Peripheral Nervous system,the CNS ensure coordination of the body activities.
Generally both the brain and the spinal cord are protected by the skull and vertebral column respectively. Their activities are based on the million of neurons which are networked by synapses.
Functions are:
processing information that is received from the stimuli receptors
sending out information so that the body can react appropriately to stimuli
coordinating reflexes and reactions to stimuli.
These functions are performed through the fast reflex pathways, for efficient coordination of the systems of the body by the CNS with PNS

Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The steps of meiosis are shown. Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?
Answers
Answer:
Crossing-over
Explanation:
Meiosis is a kind of cell division that occurs only in sexually-reproducing organisms. It is the process by which they produce gametes. Meiosis is that division in which the number of chromosomes in the resulting cells are reduced by half. Due to this reason, meiosis occurs in a two step division process viz: Meiosis I and II.
Meiosis produces genetically different reproductive cells. This is as a result of a phenomenon unique to only meiosis called CROSSING-OVER. Crossing-over is a process whereby non-sister chromatids of homologous chromosomes exchange a segment of their genetic material. It occurs only in Prophase 1 of meiosis where the TETRAD structure is formed. This exchange of genetic material causes a recombination of DNA in the resulting cell (gamete).
Crossing-over only occurs between non-sister chromatids of homologous chromosomes, hence, it can only occur in Prophase 1. Prophase II involves sister chromatids.
Answer:
Crossing-over

A strand of DNA contains 10% Guanine, what
percent is Adeninc?
Answers
Answer:
40% is Adenine.
Explanation:
In DNA, Guanine pairs with Cytosine and Adenine pairs with Thymine.
If a strand of DNA contains 10% Guanine, that means that it also contains 10% Cytosine.
10% G + 10% C = 20%
100% - 20% = 80% (Adenine and Thymine)
80% ÷ 2 = 40%
The strand of DNA contains 10% Guanine, 10% Cytosine, 40% Adenine, and 40% Thymine.
In which kind of solution is the concentration of solutes the same inside and outside of the cell? isotonic hypertonic hypotonic concentrated
Answers
Answer:
isotonic solution
Explanation:
An isotonic solution has the same concentration of solutes both inside and outside the cell. For example, a cell with the same concentration of salt inside it as in the surrounding water/fluid would be said to be in an isotonic solution.
The solutions can have various concentrations of the solutes dissolved in them. Isotonic solutions have the same concentration of solutes inside and outside the cell. Thus, option a is correct.
What are isotonic solutions?Isotonic is the type of solution that has a similar concentration of the solutes on both sides of the system like sugar and salt in the blood or body fluid. They are the essential part of the body fluid and for the balance of osmosis and diffusion.
The tonicity of the solution plays an important role in the transport mechanism and in the balance of the fluid concentration in the organism. In a hypertonic solution, the concentration is at higher levels and in hypotonic, they have fewer concentrations.
Therefore, the concentration of solutes is the same in and out of the cell in isotonic conditions.

This requires you to use all the things we have learned in this chapter. 1.55 grams of Carbon disulfide
is added to 2.83 grams of Oxygen to form Carbon dioxide and Sulfur dioxide. If the reaction yields
1.1 grams of the Sulfur dioxide what was the percent yield?
27%
14%
Ο Ο Ο Ο Ο
74%
42%
O 63%
Answers
Answer: The percent yield is, 42%
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of carbon disulphide}=\frac{1.55g}{76g/mol}=0.020moles[/tex]
[tex]\text{Moles of oxygen}=\frac{2.83g}{32g/mol}=0.088moles[/tex]
The balanced chemical reaction is:
[tex]CS_2+3O_2(g)\rightarrow CO_2+2SO_2[/tex]
According to stoichiometry :
1 moles of [tex]CS_2[/tex] require = 3 moles of [tex]O_2[/tex]
Thus 0.020 moles of [tex]CS_2[/tex] will require=[tex]\frac{3}{1}\times 0.020=0.060moles[/tex] of [tex]O_2[/tex]
Thus [tex]CS_2[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.
As 1 mole of [tex]CS_2[/tex] give = 2 moles of [tex]SO_2[/tex]
Thus 0.020 moles of [tex]CS_2[/tex] give =[tex]\frac{2}{1}\times 0.020=0.040moles[/tex] of [tex]SO_2[/tex]
Theoretical mass of [tex]SO_2=moles\times {\text {Molar mass}}=0.040moles\times 64g/mol=2.56g[/tex]
Actual mass of [tex]SO_2[/tex] = 1.1 g
Now we have to calculate the percent yield
[tex]\%\text{ yield}=\frac{\text{Actual yield }}{\text{Theoretical yield}}\times 100=\frac{1.1g}{2.56g}\times 100=42\%[/tex]
Therefore, the percent yield is, 42%

the diagram below shows a sarcomere if a disorder makes it impossible for atp to bind to the myosin head what would happen to the sarcomere?
Answers
Answer:
B. The myosin and actin would not separate, and the sarcomere would remain contracted
Explanation:
ATP (adenosine triphosphate) acts both in the binding of myosin to actin, which occurs during muscle contraction, and also in its separation, which occurs during muscle relaxation.
When ATP is lacking, myosin remains attached to actin, causing muscle stiffness. This is what happens after death, producing a state of cadaverous rigidity (also called "rigor mortis").
An intense and uninterrupted stimulation causes the muscle to reach the maximum degree of contraction. Then, the muscle remains in contraction, this state is called tetany.
A very prolonged state of tetany causes muscle fatigue, in which, due to ATP deficiency, can cause a loss of muscle contraction capacity, after its relaxation.
