Answer:
ligand; molecule; ligand; molecule; nervous system
Explanation:
Ligand-gated ion channels are membrane proteins that interact with ligands (molecules) and open in response to this binding. In the nervous system, these channels are activated by neurotransmitters (ligands) that regulate synaptic transmission between nerve cells (neurons). Neurotransmitters are signaling molecules clustered close to the cell membrane of axon terminals in presynaptic neurons. For example, glutamate is a ligand neurotransmitter that binds to ion channels and thus stimulates synaptic activity in the mammalian brain.

Name three human activities that are changing the natural world. Why do these activities make it important to understand evolution?
Explain Lamarck's ideas about how organisms changed over time.
Answer: Overharvesting, this can bring the species to extinction. Destruction of habitat is self explanatory, it can also lead to a lot of inbreeding which comes with mutations and not so good things. Pollution also fits in the same category of destruction of habitat also affecting the oxygen living things breathe.
Its correct on edge
Answer:
1. Deforestation. Cutting of trees results to the endangered habitats of animals and the soil compaction is becoming less and less.
2. Hunting. Killing animals mercilessly and selling them off reduces their numbers and increase the fear of humans
3. Genetic engineering. Modifying the cell structure of a plant or animal increases possible risk of cancer, toxicity in the soil and others.
Explanation:
Which of these statements best describes the characteristic of water that impacts its role in moderating Earth's climate?
Answer:
Water is a fluid with a high specific heat.
Explanation:
Specific heat is defined as the amount of heat energy measured in calories, that is required to change the temperature of one gram of a substance by one degree Celsius. Water has a very high specific heat of 4.184 Joules. This means that water does not get heated up or cooled easily.
This is important for earth's climate and the organisms in it as they are not subject to sudden and frequent temperature fluctuations.

Do you think wolves are a keystone species? Explain your answer
Answer:
I think that wolves are a keystone species because they regulate prey. If they were gone, prey would overpopulate and decrease the population of smaller organisms such as plants. Without plants and other food sources for the prey, the prey would also decrease eventually.

Plants on land and in the ocean convert carbon dioxide to biomass through photosynthesis.
What do you mean by photosynthesis?Plants and other organisms use a process called photosynthesis to transform light energy into chemical energy that can later be released to power the organism's activities through cellular respiration.
A chemical reaction that occurs when sunlight is applied to algae, plants, and some bacteria. During photosynthesis, water and carbon dioxide join to frame carbs (sugars) and radiate oxygen.
In plants and green growth, which grew a lot later, photosynthesis happens in a specific intracellular organelle — the chloroplast. During daylight, chloroplasts perform photosynthesis.

Answer:
The incorrect statement is -C. They are ALL parasites that harm their host by living in or on it.
Explanation:
Protists are organism shows the vast difference and have a single cell microscopic eukaryotic cell. These are based on their characteristics similar to plants or animals divide them into two groups called plant-like protists and animal-like protists.
Animal-like protists are also a eukaryotic unicellular organism that depends on other organisms for their food so they are called heterotrophs. Some of these organisms also parasites and affect their host negatively. These are also organisms that are live symbiosis and help other organisms.

if i need 3/4 cup of oats for a batch of muffins how much muffins can i make with 1 1/2 cups of oats
She can make 2 batches of muffins from 11/2 cups of oats.
What is Muffin?A muffin is an individually portioned baked product, however the term can refer to one of two distinct items: a part-raised flatbread (like a crumpet) that is baked and then cooked on a griddle (typically unsweetened), or an (often sweetened) quickbread (like a cupcake) that is chemically leavened and then baked in a mold.
While quickbread "American" muffins are often sweetened, there are savory varieties made with ingredients such as corn and cheese, and less sweet varieties like traditional bran muffins.
The flatbread "English" variety is of British or other European derivation, and dates from at least the early 18th century, while the quickbread originated in North America during the 19th century.
Therefore, She can make 2 batches of muffins from 11/2 cups of oats.

11. Which of the following would be the best way to mitigate (reduce the impact of) deforestation?
Employ clear cutting harvest techniques that are more sustainable.
Stimulate intensive agricultural production of native vegetation close to villages.
Grow more diverse timber products to increase economic value in an area.
Replant and protect trees in areas that have been previously cleared.
Answer:
Replant and protect trees in areas that have been previously cleared.
Explanation:
A large clearing of the plantations and trees from an area is called deforestation. Due to deforestation soil erosion, change in the water cycle, flood etc. occurs.
The correct answer is:
Option D. Replant and protect trees in areas that have been previously cleared.
This can be explained as:
Re-plantation of the trees and vegetation in the cleared area will help in mitigating deforestation.Sustainable harvesting techniques do not have an effect on deforestation.Intensive agriculture techniques will not help in restoring the deforested lands.Therefore, re-plantation is the method to mitigate deforestation.

At which location along a river or stream would the greatest rate of erosion most likely occur?
A. at its point nearest to the ocean
B. at its steepest incline
C. at its widest point
D. at its origin
Answer:
B. at its steepest incline
Explanation:
The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.
Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.
Hence, the location along a river or stream at which the greatest rate of erosion would most likely occur is at its steepest incline.
The study of rivers is called limnology.
The correct answer to the question is B that is at its steepest incline
What is erosion?The removal of the upper layer of soil is called soil erosion.
According to the question, The steepness of a body such as a river or a stream refers to the downward slope or gradient of the body of water. Generally, the steepness of a body affects the rate at which other materials would flow or move around.
