Which of the organisms in the food web could be referred to as primary consumers?
7 only
5 and 6 only
2, 3, and 4 only
2, 5, and 7 only
Answers
Explanation:
2 , 3 and 4 only because they the first ones to eat
The main producers are found at the bottom of the food chain. Autotrophs, or primary producers, are often photosynthetic organisms like plants, algae, or cyanobacteria. The organisms that eat primary producers are known as primary consumers. Thus, option C is correct.
What organisms in food web as primary consumers?Herbivores devour most of the food. Grazers consume plants, algae, and other food sources. The second trophic level is where they are. Deer, mice, and even elephants are herbivores in a grassland ecology.
The second trophic level consists of primary consumers. Herbivores are another name for them. Only primary producers like plants or algae are eaten by them. A grasshopper living in the Everglades is an illustration of a primary consumer.
Therefore, 2, 3, and 4 only of the organisms in the food web could be referred to as primary consumers.

What is the measured output force of a pulley system if the Mechanical Advantage is 0.48 and measured input force is 10N?
Answers
Answer:
Output force is 4.8 N
Explanation:
A pulley is a simple machine made of a grooved wheel with a rope or cable wrapped around it. Pulleys are used in the transmission of energy or motion.
The input force is also known as the applied force while the output force is the force exerted on an object by a simple machine.
The mechanical advantage of a pulley is the ratio of the output force to the input force.
Mechanical advantage = output force / input force
Substituting:
0.48 = output force / 10
Output force = 4.8 N

If there is more greenhouse gases in the atmosphere, how much of solar radiation leaves the atmosphere?
Answers
However, only around 12% of the solar energy that enters the atmosphere is directly lost to space. When greenhouse gas molecules absorb thermal infrared energy radiated by the surface, a net 5-6 percent of incoming solar energy is transported to the atmosphere.
Answer:
less
Explanation:
Because those green house gasses act like a blanket that allows short wavelength radiations into the earth and due to interaction with the things in the earth, long wavelength radiations are produced which prevented from leaving the earth by the same blanket. Therefore the more the blankets(green house gasses), the more the radiations are trapped.

The hemoglobin protein of a human and a frog differ by 67 amino acids. How many amino acids are most likely different between a human and a chimp?
A. none
B. fewer than 67
C. 67
D. more than 67
Answers
Answer:
B. Fewer than 67
Explanation:
Humans are much more closely related to chimps than frogs, so the genetic information that codes for their proteins will differ much less.
Based on the evolutionary relationship between humans and chimpanzees, it is highly likely that humans and chimpanzees share a large portion of their genetic material, including the amino acid sequence of hemoglobin. Therefore, it is most likely that the answer is B. Fewer than 67 amino acids are different between a human and a chimp.
What is the hemoglobin of different animals?The hemoglobin protein is a vital protein in both humans and chimpanzees that helps transport oxygen in the blood. While there may be some variations in the amino acid sequence of hemoglobin between humans and chimpanzees, it is expected that most of the amino acids will be the same since hemoglobin performs a critical function in both species. Additionally, any differences in the amino acid sequence of hemoglobin between humans and chimpanzees are likely to be fewer than 67, as this is the number of differences between humans and frogs, which are much more distantly related species.
Hence, it is most likely that the answer is B. Fewer than 67 amino acids are different between a human and a chimp.

A tropical rainforest includes trees, animals, insects, plants, rain, rivers, rocks, soil, and warm, moist air.
Which spheres of Earth are represented in a tropical rainforest?
O biosphere, geosphere, hydrosphere
O cryosphere, hydrosphere, ionosphere
O geosphere, biosphere, cryosphere
ionosphere, hydrosphere, geosphere
Answers
Answer:
The answer is A
Explanation:
The hydrosphere provides almost all the water at or near the earth's surface. It is important to the biological and geological processes as it is a continuous cycle of recycling water between the oceans and atmosphere.
A tropical rainforest is a representation of the Earth's biosphere, geosphere, and hydrosphere, hence option A is correct.
What are the spheres of Earth?Trees, animals, insects, rivers, rocks, soil, and warm, humid air make up the tropical rainforest. The ecosystem, which consists of both living organisms (animals) and inanimate objects, is referred to as the biosphere.
This encompasses ecosystems where there are rocks and other buried minerals, such as those found in tropical rainforests.
The hydrosphere is also accurately represented in the tropical rainforest since there are rivers and rain there.
Therefore, we may deduce that a tropical rainforest represents the biosphere, geosphere, and hydrosphere of the planet.

Using the words "selection pressure" and "fitness", explain how natural selection causes populations to change over time.
Answers
Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.

James needed to have his hernia surgically repaired. This can be done through laparoscopic surgery. The surgeon must cut through to the herniated area and put a Teflon mesh underneath the hernia to close it off and provide more support to the area. Use your knowledge of anatomy to select the correct sequence of structures that would be cut for this procedure. Make sure you select the structures in the order they would be cut by the surgeon.
Answers
Answer:
The structures that the surgeon will cut to place the Teflon mesh from external to internal are:
Skin,
hypodermis,
subcutaneous fat,
the external oblique aponeurosis,
the internal oblique,
the transverse abdominal,
the peritoneum.
Explanation:
For the surgeon to put the Teflon mesh underneath the hernia, the professional has to cut the most external organ, which is the skin, with all its layers, epidermis, dermis, and hypodermis. Underneath this tissue is the subcutaneous fat, which protects the muscles, regulates the temperature, and stores energy. Subcutaneous fat is different in every person. Some can have a lot of it and others a thin layer. The next cut will be on aponeurosis, which is a tissue that surrounds muscles. Then we have the internal abdominal oblique, which is in the anterior area of the abdomen. Below it, it is the transverse abdominal, and then the peritoneum, which is the tissue that holds the organs. In a hernia, it has a hole where the organs push through. So, the surgeon has to put a Teflon mesh to close it.

What is the main difference between combustion and respiration?
A. respiration occurs at high temperatures without enzymes to release energy
B. respiration uses enzymes at normal body temperature to release energy
C. combustion uses enzymes at normal body temperature to release energy
D. respiration does not use a catalyst but combustion does use a catalyst
Answers
Answer:
A. respiration occurs at high temperatures without enzymes to release energy
Explanation:
The respiration is the transfer of oxygen from the environment to the cells and removal of carbon dioxide from the cells is often referred as cellular respiration by which an organism obtains an energy.
But combustion is the burning of any hydrocarbon fuel in the air resulting the liberation of heat energy and other combustion by products like carbon dioxide, steam and Nitrogen. Practically, in addition to these gases there may also be the presence of sulphur dioxide, nitric oxide and oxygen which depends upon the composition of fuel and the amount of air supplied for combustion.
