Watch this video about a river that China is building. Explain how the river will help prevent the negative effects of drought. In your answer, explain any negative effects that you foresee this new river will have on the people or on natural habitats.
Answer: The river will increase Beijing’s water supply, which is currently at risk of not meeting the city’s needs. This increase will help to soften the effect of droughts.
The downside of the new river is that it may disrupt natural areas, including habitats for plants and animals. The project will also be expensive and may take up space that could be used for homes, businesses, or agriculture.
Explanation: Change the wording...
The construction of a new river can help prevent the negative effects of drought by increasing the availability of water for human and ecological needs, and one way that a new river can help prevent the negative effects of drought is by increasing the recharge of groundwater resources.
What is a drought?During periods of drought, water resources can become scarce, leading to reduced crop yields, drinking water shortages, and negative impacts on ecosystems. By providing a new source of water, a new river can help alleviate some of these negative effects. A new river can provide a source of water that can help recharge aquifers and replenish groundwater supplies. However, the construction of a new river can also have negative effects on people and natural habitats. One potential negative impact is the displacement of people living in the area where the river is being constructed. This can lead to the loss of homes, farms, and livelihoods for local communities.
Hence, the construction of a new river can help prevent the negative effects of drought by increasing the availability of water for human and ecological needs.

Complete each sentence with the correct word or phrase
a. An action potential reaches the axon terminal causing __________to open.
b. Acetylcholine diffuses across the synaptic cleft before binding to its receptor, which is located on the _____
c. When the membrane potential reaches ________an action potential spreads across the sarcolemma due to the opening of ___________
d. In response to acetylcholine binding, ________ move into the muscle fiber causing the membrane potential to rise.
Answer:
a). Voltage-gated Ca2+ channels
b). the motor end plate
c). Threshold, voltage-gated Na channels
d). sodium ions
Explanation:
a). The voltage-gated [tex]Ca^{2+}[/tex] channels are the key transducers of the membrane potential that changes into a intracellular [tex]Ca^{2+}[/tex] transients which initiates the physiological events. When the action potential makes a contact with axon terminal, the voltage-gated [tex]Ca^{2+}[/tex] channels opens.
b). The acetylcholine is the main neurotransmitter of the parasympathetic nervous system. It helps in blood vessels dilation, muscle contraction, and perform many more functions.
It diffuses with the synaptic cleft that is located on the motor end plate of the nervous system.
c). The membrane potential is also known as the membrane voltage or the transmembrane potential. When it recaches the threshold, the voltage-gated Na channels opens to spread the action potential across sarcolemma.
d). The sodium ions in case of acetylcholine binding moves to the muscle fiber due to which the membrane potential rises.

You are a research biologist working at the U.S. research station in Antarctica. You discover a new single-celled organism that is able to survive in the frigid conditions. During your research you observe that the organism has a nucleus. Which domain would this new organism be classified into
Answer: Eukarya.
Explanation:
The cell is the functional and morphological unit of all living beings. Organisms can be classified as follows: if they are composed of a single cell, they are called unicellular (such as protozoa or bacteria which are microscopic organisms), or mutlicellular if they have more cells.
The three-domain system is a biological classification into three groups:
Archaea Bacteria Eukarya.It is based on the differences found in the sequence of the ribosomal RNA of the minor subunit to conclude that these groups developed separately from a common progenitor.
Archaea are a group of unicellular prokaryotic microorganisms that have no nucleus or any internal membranous organelles. However they are different from bacteria, so that they form their own domain.
Bacteria are prokaryotic microorganisms that do not have a defined nucleus nor do they generally have internal membranous organelles.
Although archaea and bacteria are morphologically very similar, archaea are closer to eukaryotes in some genes and pathways of transcription and translation. Thanks to studies of genetic material, now we knot that the evolution of archaea and bacteria had been independent, so archaea could no longer be considered as a group of bacteria. However, the Archaea and Bacteria domains include prokaryotic organisms, i.e. those whose cells do not have a differentiated cell nucleus.
The Eukarya domain includes the best known and most complex forms of life (protists, animals, plants and fungi). It includes organisms formed by cells with a true nucleus. These organisms consist of one or more eukaryotic cells, ranging from unicellular to multicellular organisms in which the different cells are specialized for different tasks and which, in general, cannot survive in isolation.
So, if the observed organism possesses a nucleus, then it is a eukaryote.

What is the result of a mutation during meiosis
Answer:
There's a change in the DNA sequence
Explanation:
If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population. Mutations are the sole source of genetic variability that can occur in asexual reproduction. But the effects of mutations can vary widely, from being beneficial, to having no effect, to having lethal consequences, and every possibility in between.
Pharmacological management of glaucoma focuses on the reduction of intraocular pressure by increasing the drainage of aqueous humor, decreasing the production, or both. What drug classes are used to reduce intraocular pressure
Answer:
Beta blockers.
Explanation:
Beta blockers are the drugs that blocks the effects of the hormone adrenaline. Beta blockers is responsible for slowing of your heart beat more which ultimately reduce blood pressure. Beta blockers are the drugs which reduce the production of fluid in your eye, thereby lowering the pressure in your eye means intraocular pressure. Examples of beta blocker medicines are timolol (Betimol, Istalol, Timoptic) and betaxolol (Betoptic).
