Does it matter if all dichotomous keys for the same group of organisms are different?
Answer:
Yes, more than one dichotomous key be developed to identify the same group of organisms. The reason that more than one dichotomous key for the identification of the same group of organisms is possible is that the organisms are identified by a number of different characteristics and one person developing a key might use a different set of characters from another person.

There is 0 net force acting on the blocks (that are at rest) from all directions except the top.
Explanation:
This is because nothing is moving; no forces are occurring for the blocks to move, which is why the blocks aren't moving. However, there is a force acting on the blocks at rest, and that is gravity. Gravity is keeping the blocks to the floor.

“Collect and present information on US hurricanes and Typhoons/Cyclones that have hit Asia.”
Does it mean for me to collect information on “US hurricanes and Typhoons/Cyclones”that have hit Asia
Or does it mean “US hurricanes” and “Typhoons/Cyclones that have hit Asia”
Please help I don’t get it
Answer: I think it wants you to collect information on US hurricanes, and also collect information on Typhoons/cyclones that hit Asia. Since I don't think hurricanes happen in Asia. And a US hurricane would definitely not reach Asia. Oh and the word 'hurricane' isn't used to describe the typhoons/cyclones that happen in Asia.
Answer:
In my opinion I think it wants you to collect information on US hurricanes, and also collect information on Typhoons/cyclones that hit Asia. Since I don't think hurricanes happen in Asia.

Giant anteaters live in Central and South America. As their name suggests, they eat ants and termites. First, an anteater tears open insect nests with its long claws. Then, it extends its extremely long, sticky tongue into the nest to catch its prey. One anteater eats 35,000 ants and termites in a day.
Look at the table showing the Linnaean levels of classification for the giant anteater. Then create the scientific name for this species. Choose the best option for each part of the name. (What is its scientific name?)

Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores. Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.
Herbivores. Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores.
What are Primary consumer?Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.
An alligator (Alligator mississippiensis) snoozes on the bank of a slow-moving water channel on a sawgrass prairie in the Florida Everglades. In the shallows, a great egret (Ardea alba) is pursuing fish. An aster leaf is being chewed by a grasshopper (Brachystola magna).
Every ecosystem has living things that work together to distribute energy in predictable ways. A trophic pyramid, as it is known among scientists, can depict these interconnections.
Therefore, Herbivores. Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores.

What are the pros and cons of GMO's
Answer: A pro '' Easier to ship and resistance to pest.'' A con '' Environmental risk and only rich countries can afford it.''
Explanation:
Advantages of GMO foods include added nutrients, fewer pesticides, and cheaper prices and disadvantages of GMO foods can be allergic reactions or increased antibiotic resistance.
What do you mean by genetically modified organisms?Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism.
Most of the GMO crops grown today were developed to help farmers prevent crop and food loss and control weeds. The three most common traits found in GMO crops are: Resistance to certain damaging insects.
Potential health risks to humans include the possibility of exposure to new allergens in genetically modified foods, as well as the transfer of antibiotic-resistant genes to gut flora.

1. Where does the body get glucose molecules?
2. Where does the body get amino acids?
3. Where does the body get oxygen?
4. What do you think could happen if the human body doesn’t take in one or all of these molecules? Why do you think this?
Answer:
1. Glucose molecules come from the food we eat. we digest the food, then it mixes with acid/enzymes in the stomach. then the food breaks down and becomes glucose (blood sugar).
2. the best place to get amino acids is through protein-rich foods. when you eat protein, it gets broken down into amino acids, which are used for building muscle and "regulating immune function"
3. enters through the alveoli. it exchanges with older air in the lungs.
4. A. glucose- cause low blood sugar, causing problems in your nervous system
B- amino acids-decreased immunity, fertility issues, slowed growth (in children), digestion problems, and depression.
C- oxygen- basically suffocation, which leads to death
