The enzyme choline acetyltransferase catalyzes the reaction between acetyl-CoA and choline resulting in the formation of the neurotransmitter acetylcholine. This enzyme is produced within the cell body of neurons, but the synthesis of acetylcholine occurs within the axon terminals. What best describes the axonal transport mechanism associated with this process?
Answer: Anterograde direction.
Explanation:
Choline acetyltransferase is an enzyme made in the body of a neuron and that needs to be transferred to the axon terminal to perform its function. Its function is to bind acetyl-CoA to choline to form the neurotransmitter acetylcholine.
The movement toward the cell body is called retrograde transport and the movement toward the synapse is called anterograde transport. So, since it is produced in the body of the cell and it has to go to the axon terminals, the choline acetyltransferase is transported in the anterograde direction.
This type of transport is responsible for the movement of organelles such as mitochondria, lipids, synaptic vesicles, proteins from a neuron cell body through the cytoplasm of its axon called the axoplasm. Because axons can sometimes be meters long, neurons cannot rely on diffusion to carry products to the end of their axons. Dynein is a motor protein involved in this retrograde axonal transport. Its light chains bind cargo, and its globular head regions bind the microtubule, "moving forward" along it.
What are the scientists doing incorrectly? What could they do to make their work in the lab safer? Why is it important to follow these procedures? Part A
Answer:
Part A
The scientists threw away their instructions. They should have kept their instructions to properly and safely follow all procedures. Following instructions also ensures useful experimental results.
Part B
The scientist is not wearing safety goggles. He should wear goggles during activities that can harm his eyes. Working safely to avoid injury is every scientist’s job.
Part C
The lab area is messy and needs better organization. The scientist should carefully store the test tubes that aren’t being used. A clean work area helps scientists work safely and efficiently to avoid costly accidents.
Part D
The scientist is disposing of dangerous materials incorrectly. He should have followed disposal instructions as described in the lab procedure. Improper disposal can pollute the environment, harm fragile wildlife, and damage facilities. Scientists must be environmentally responsible.
Part E
The scientist didn’t clean up after an accident. He should have disposed of the glass immediately after it broke rather than waiting. Accidents create hazards for scientists and those around them.
Part F
Scientists should not eat or drink in a lab area. They could swallow something harmful or foul. Snacks and meals should be eaten during designated breaks and never near the lab area.

An example of transamination is finding a brand new sports car in your driveway with your name on it. removing a phosphate group from a molecule. removing an amino group and putting it into the bloodstream for the kidneys to discard. removing an amino group from one molecule and binding it to a different molecule.
Answer:
removing an amino group from one molecule and binding it to a different molecule.
Explanation:
Biological macromolecules can be defined as a very large molecule (structure) that comprises of covalently bonded organic atoms and smaller molecular structures (monomers).
Biological macromolecules are categorized into four main categories and these includes;
I. Lipids.
II. Carbohydrates.
III. Nucleic acid.
IV. Proteins.
Generally, proteins comprises of amino acids and it is responsible for maintaining the proper functioning of the body system.
Transamination can be defined as a biochemical process which typically involves the removal of amino groups from amino acids and transferring them to a ketoacid (amino acid without an amine group), so as to form new amino acids.
Basically, transamination is a reversible oxidation-reduction reaction that is responsible for the deamination of amino acids.
Hence, an example of transamination is removing an amino group from one molecule and binding it to a different molecule.

Why are economic impacts important to consider when planning to address climate change? Wealthy people and businesses won't support changes if the changes are not beneficial to them in the short term Climate change is the most significant danger humans face in the next 100 years We only have limited resources and so should use them where they will do the most good Without substantial economic sacrifice the world will suffer significant, inextricable (cannot be undone) damage due to climate change
Answer:
The projections, if they play out, illustrate the potential magnitude of decisions such as the recent one by President Trump to walk away from the international Paris climate accord, in which more than 170 countries agreed to slash their carbon emissions in coming years. Meanwhile, hundreds of governors, mayors and other elected officials have vowed to continue the shift toward cleaner sources of energy.
Hsiang acknowledged that despite the researchers’ efforts to use sound statistical approaches and a wealth of databases, calculating the future costs of climate change is inherently uncertain. Communities are likely to adapt and become more resilient. Industries evolve and relocate.
Delavane Diaz, a senior technical leader at the Electric Power Research Institute, agreed that the study has limitations. For one, it fails to account for how humans will probably plan for and respond to the changing climate. Still, she said, the conclusions provide an important glimpse of the economic risks the United States could face as global warming worsens.

When blood glucose levels rise, the hormone ___ is released from the ___ to convert excess glucose into glycogen, a short-term energy storage molecule for the body.
Answer:
insulin; pancreas.
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Generally, when the blood glucose levels of a person rise, through an endocrine system, the hormone known as insulin is released from the pancreas to convert excess glucose into glycogen, which is typically a short-term energy storage molecule for the body.
In conclusion, the endocrine system maintain homeostasis by releasing insulin from the pancreas to decrease blood sugar and releasing glucagon to increase blood sugar.

An organism has the following characteristics: cell wall, heterotrophic, unicellular, and prokaryote. What kingdom does
it belong in?
• Animalia
• Protista
• Plantae
•Eubacteria
Answer:
The correct answer is - Eubacteria.
Explanation:
Eubacteria is a kingdom that comes under prokaryotic organisms. These organisms have many characteristic features that are as follows:
Body Structure: Eubacteria are single-celled organisms with a cell wall outside of the cell to protect them.
Food: Eubacteria are both auto- and heterotrophic which means they can be either autotrophic, they use both chemical synthesis and photosynthesis.
Animals lack the cell wall, planate are autotrophic and protists are eukaryotic organisms so the correct answer is eubacteria.

Answer:
In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells).
Answer:
E
Explanation:
Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in the thymus gland.
Match the hominin with the best description.
Late Pleistocene hominins found only in Europe, Western Asia, and Central Asia; the Shanidar site belongs to this group.
Middle Pleistocene hominin; found in Africa, Asia, Europe; shows a mixture of features from previous and later hominins.
Answer:
- Late Pleistocene hominins found only in Europe, Western Asia, and Central Asia; the Shanidar site belongs to this group: Neandertals
- Middle Pleistocene hominin; found in Africa, Asia, Europe; shows a mixture of features from previous and later hominins: Homo_heidelbergensis
Explanation:
Neandertals represent an extinct hominid lineage and the closest evolutionary relatives of humans. Neandertals lived in Europe, Central Asia, the Middle East and western Siberia. This group of extinct hominids appeared around 130,000 years ago until their extinction, approx. 40,000 years ago. On the other hand, Homo_heidelbergensis is an extinct group of Homo_Hominids who lived during the Middle Pleistocene, a time period spanning 780,000-120,000 years ago. Homo_heidelbergensis is considered the most recent common ancestor between H. sapiens (modern humans) and Neanderthals. This species (Homo_heidelbergensis) combined primitive features (e.g., a wide face, and thick arching brow ridges) with modern features (e.g., a large brain capacity).

A mutation in Complex I decreases the efficiency of the electron transport chain. However, not all components of the electron transport chain are affected by this mutation. Which component of the electron transport chain will remain unaffected by a mutation in Complex I?
a. Ubiquinone
b. Complex II
c. Complex III
d. Complex IV
Answer:
b. Complex II
Explanation:
The electron transport chain is a sequential series of proteins located in the inner membrane of the mitochondria that act to transfer electrons from different members of the transport chain in a series of redox reactions, which is coupled to the movement of protons (H+) across the membrane. Complex I (also called NADH dehydrogenase or NADH- CoQ reductase) accepts electrons from NADH and passes them to Complex III (also known as coenzyme Q reductase), which also receives electrons from Complex II (succinate coenzyme Q reductase). Ubiquinone (Coenzyme Q) accepts electrons from both complex I and complex II and transfer them to complex III. From complex III electrons pass to complex IV through cytochrome c oxidase and finally to molecular oxygen (O2, the final electron acceptor). In consequence, Complex I and Complex II are linked by different pathways to Complex III, thereby it is expected that Complex II remains unaffected by a mutation in Complex I.
What colors of light are absorbed? Which color is not absorbed?
Answer:
All colour except which is already present in the body.
Explanation:
The plant leaf has green colour so the plant absorb all the colour except green. The presence of green colour causes reflection of green colour so that's why we can see the green colour of the leaves. Every material or substance have a specific colour which can be seen when they absorb all light except the colour which is already present in it so we can say that that colour is not absorbed by the body which is already present in it.
which water pollutants can lead to excessive growth of water weeds
Answer: Water pollution also affects the ecosystem – it can cause a phenomenon called eutrophication. This can cause fish and other aquatic organisms to die. Toxic elements dissolved in water can make their way to humans through fish or other aquatic organisms.
https://byjus.com/biology/effects-of-water-pollution/
