Answer:
neurotransmitter is released
Explanation:
A neuromuscular junction is defined as the chemical synapse between a muscle fiber and the motor neuron. When the neuromuscular junction are put into a sequence, the third event is released of the transmitter. The action potential depolarizes the terminal membrane [tex]$Ca^{2+}$[/tex] rushes in releasing the neurotransmitter.

Evidence supporting E.coli DNA polymerase III having the major role in nucleotide incorporation during replication includes: Evidence supporting E.coli DNA polymerase III having the major role in nucleotide incorporation during replication includes: A point mutation can inactivate DNA pol III and inhibit replication. DNA polymerase III has a high Vmax. There are ten or fewer molecules of enzyme per cell. Replication is blocked at high temperatures in temperature sensitive mutants with a thermolabile form of DNA polymerase III. All of the above.
Answer:
All of the above
Explanation:
The DNA polymerase III is a multi-subunit enzyme which is essential for the synthesis and activation of the majority of the genome in Escherichia coli.
DNA replication is random in both prokaryotes and eukaryotes, causing several DNA polymerase to synergistically replicate the continuity (leading) and discrete (lagging) DNA strands.
The points that are given support and reflect the assertions that E.coli DNA polymerase III plays a very important role in nucleotide incorporation during replication.

Why does temperature decrease with higher altitude?
A.
Air is held strongly together by gravity, so there is less heat transfer.
B.
Air density is lower, so there is less heat transfer.
C.
Air density is higher, so there is less heat transfer.
D.
Air pressure is higher, so there is less heat transfer.
Answer:
air density is lower, so there is less heat transfer
Explanation:
Radiation is absorbed by the ground of Earth and this heats the surroundings along with tropospheric air through conduction and convection process. ... Thus, we can conclude that temperature decrease with higher altitude as air density is lower, so there is less heat transfer.
Answer:
The correct answer would be B.
Air density is lower, so there is less heat transfer.
I got this right on a test. I hope this helps!

Which of the following nutrients is organic?
iron
water
sodium
protein
Answer:
Protein is the answer
Explanation:
Proteins are considered organic molecules because they are made up of carbon atoms with hydrogen, oxygen and nitrogen attached
______ can amplify the effects of temperature by increasing the rate of heat loss by convection.
Answer:
wind
Explanation:
As the air heats up and becomes less dense, it rises higher into the atmosphere, thereby cooler air takes its place and produces wind (moving air is wind). This wind can produce a positive feedback loop that increases the transfer of heat by both evaporation (i.e., by losing heat through the conversion of water to vapor) and convection (i.e., through the movement of air). In consequence, wind created by temperature fluctuation can amplify the effects of temperature. In organisms, winds can also contribute to water loss by increasing the evaporation/transpiration rate.
Match each description with the correct cellular process. a. RNA is used as a template to make a complementary strand of DNA. (Click to select) b. DNA is used as a template to make a complementary strand of DNA. (Click to select) c. RNA is used as a template to make a complementary strand of RNA. (Click to select) d. DNA is used as a template to make a complementary strand of RNA. (Click to select) e. RNA is used as a template to make a polypeptide. (Click to select)
Answer:
d. DNA is used as a template to make a complementary strand of RNA - Transcription
Explanation:
This question is describing the process of TRANSCRIPTION, which is the first process involved in gene expression or protein synthesis. Transcription is the process by which a DNA template is used to synthesize a mRNA strand.
The process of transcription, which occurs in the NUCLEUS of an eukaryotic cell involves making a complementary strand of RNA (messenger RNA) from a DNA template. For example, a nucleotide A (adenine) in the mRNA will pair with a nucleotide U (uracil) on the mRNA.

Which of the following is an example of an animal being harmful to the environment?
A. Wolves eat deer to keep the number of deer down,
B. Worms build tunnels in the dirt for air and water,
C. Carpenter ants eat wood found in people's homes.
O D. Horse manure fertilizes the
soil.
Answer:
C. Carpenter ants eat wood found in people's homes.
Explanation:
Although a home is not a natural environment, it still is a part of one. The damage that carpenter ants create by eating the wood can be detrimental to the house's stability. It is very expensive and time consuming to fix.
Why are drugs that disrupt the mitotic spindle effective cancer treatments
Answer:
Since microtubules are important components of mitotic spindles, the disruption of microtubule dynamics by these drugs arrests cell division, thereby preventing cancer growth.

Select the star life cycle that is most accurate
The correct answer is A. Nebula, star of seven stellar masses, a red supergiant, supernova, black hole.
Explanation
Stars have a life cycle that begins with the gravitational collapse of a gaseous nebula. Subsequently, thermonuclear fusion occurs that allows the conversion of hydrogen into helium, this causes the released energy to pass through the star and radiate in a phase called the star of seven stellar masses. After several billion years, the star passes to the "red giant" stage. Here the star contracts and raises its temperature. After this, the stars (which have masses greater than the sun) detach from their layers forming supernovae, and later, these give rise to "black holes". According to the above, the correct answer is A. Nebula, star of seven stellar masses, a red supergiant, supernova, black hole.
Answer:
The answer is A Just took the test
Explanation:
When a pregnant woman ingests toxins such as alcohol and
nicotine, the embryo is put at risk because these toxins can
1) diffuse from the mother's blood into the embryo's
blood within the placenta
2) enter the embryo when it eats
3) transfer to the embryo since the mother's blood
normally mixes with the embryo's blood m the placenta
4) enter the uterus through the mother's navel

• How gamete formation leads to genetic variation.
Answer:
Genetic variation is increased by meiosis
During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

Part C Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions are 1.2.luciferin+O2ATP⇌⇌oxyluciferin+lightAMP+PPiΔG∘=−31.6 kJ/mol If the overall ΔG∘ of the coupled reaction is -4.80 kJ/mol , what is the equilibrium constant, K, of the first reaction at 6 ∘C ?
Answer:
K = 9.620 × 10⁻⁶
Explanation:
From the given information:
Temperature T= 6° C
= (273 + 6)K
= 279 K
The correct and well presentation of the reactions are:
1. [tex]Luciferin + O_2[/tex] ⇆ oxyluciferin + light ΔG₁°
2. ATP ⇄ AMP + PP[tex]_i[/tex] ΔG₂° = -31.6 kJ/mol
The overall ΔG° = -4.80 kJ/mol
Let's first determine the ΔG₁° for the equation (1)
ΔG° = ΔG₁° + ΔG₂°
- ΔG₁° = - ΔG° + ΔG₂°
ΔG₁° = ΔG° - ΔG₂°
ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol
ΔG₁° = 26.8 kJ/mol
Using the formula:
ΔG° = -RTIn K
[tex]In \ K =\dfrac{-\Delta G^0}{RT} \\ \\ log \ K = -\dfrac{\Delta G^0}{2.303RT}[/tex]
[tex]log \ K = -\dfrac{\Delta G_1^0}{2.303RT} \\ \\ log \ K = -\dfrac{26.8 \times 10^3 \ J/mol}{2.303\times 8.314 \ J/mol/K \times 279 \ K} \\ \\ log \ K =- 5.017[/tex]
K = antilog (-5.017)
K = 9.620 × 10⁻⁶
