A mushroom gains its energy by decomposing the tissues of dead organisms. Should mushrooms be classified as autotrophs, heterotrophs, in both groups, or in neither group, and for what reason?
They are heterotrophs because their food is made by other organisms.
They are autotrophs because decomposition is very similar to photosynthesis.
They are both autotrophs and heterotrophs, because they may grow in sunlight or darkness.
They are autotrophs because they do not eat their food, as animals do.
Answer:
They are heterotrophs because their food is made by other organisms.
Explanation:
Unless the organism can create their food independently via photosynthesis or chemosynthesis, they must get their food from elswehere.
In the case of mushrooms, they are scavengers/decomposers, meaning they consume energy from once living organisms, thus classifying them as heterotrophs.
Have a nice day!
Which is an example of poor safety practices when working outdoors? O A. Wearing gloves when dealing with animals O B. Washing your hands afterward O C. Treating animals with respect O D. Feeding wild animals
Answer:
D. Feeding wild animals
Explanation:
they could bite ya
Answer:
D-Feeding wild animals.
Explanation:
If you look at A, B, and C, you’ll see that that would be something that you should do, because B is good hygien, C is that you should respect others (and to be honest if you don’t respect them they might attack because your not respecting them), A is that you should wear gloves when you deal with animals because what if the animal had a disease or sickness? If you didn’t have gloves, you could catch whatever they had. D is poor safety because wil animals are not tamed yet, so you don’t know what they can do, so you shouldn’t even be close to them.

Explanation:
Is The Hill (thehill.com) a trusted news website or does it have a strong bias?
From what I’ve seen, The Hill’s news reporting is pretty even handed and accurate, although the site is considered to be slightly right leaning.
However, they also employ John Solomon as their executive VP of digital video and as a columnist. With a strong background in investigative journalism, his work of late has descended into promoting baseless conspiracy theories, like the widely discredited Uranium One. I’ve seen stories of his promoted by the right-wing media in the past couple of years that have fallen apart under scrutiny.
UPDATE (5–23–2020): Someone a couple of revisions that I rejected. Nothing about spelling or grammar. This answer was accurate when it was written, although The Hill has since parted with Solomon. Brendan Delaney’s second edit suggestion was not only inaccurate, but would have made the answer his own. Better that he simply answer the question himself or make his points in a comment. But then again if you do think about it Well…John Solomon was their chief editor for a long time and he’s a hard-right, loony conspiracy theorist nutbar. The site is also owned by Jerry Finkelstein, who is good friends with Trump. Furthermore, The Hill does gives face time to a lot of hard-right opinion pieces.
On the flipside, they ARE a good aggregator of political news and publish stories you won’t find elsewhere, which balances things out somewhat.
Solomon left a few months ago Fox News and The Hill seems to be making an honest effort to balance their editorial more. Jury is still out on whether they’ll be successful or not.
Explain how mutations cause cancer cells.
Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Explanation:
Answer:
Disclaimer: I haven't had a proper science class in ages and I forgot most of the terms. I probably don't have the correct answer that you're looking for, but this is to the best of my ability.
Mutations in cells can cause cancer as it will compete with other cells for energy and space. It will continually multiply/rapidly grow and can't be rid of as its internal system of apoptosis was hindered during the mutation. Mutations can occur due to damages in the DNA.
2. In your own words, describe how you can use the stars to locate the
sky's North Pole.
Answer:
Explanation:
You can use the Big Dipper to find Polaris, which is also known as the North Star. Notice that a line from the two outermost stars in the bowl of the Big Dipper points to Polaris. And notice that Polaris marks the tip of the handle of the Little Dipper. The northern sky is a large clock, with Polaris at its center.
Answer:
Look North and read the pattern the sky has, usually Northern constellations

What needs to happen for recessive traits to be observed in an organism?
Answer:
For recessive traits to be observed, dominant genes must be absent.
Explanation:
There are 3 possibilities for the genes: AA, Aa, aa.
in both AA and Aa, there is a dominant gene present. If a dominant gene is present, it will always show the dominant trait.
In aa, there is no dominant gene present, and there are only recessive genes. Because of this, the recessive trait is observed!

There are thousands of different
proteins being produced within the
cell. How does a cell 'know' which
proteins to produce?
A. The ribosomes produce the proteins by
communicatiing with the cell.
B. The DNA segments code for different protein
production.
C. All proteins are the same.
Answer:
I think its A...
Explanation:
Because a cell has to communicate with someone to identify the objects or things that goes inside it.
The ribosomes produce the proteins by communicating with the cell. The correct option is A.
What are ribosomes?Ribosomes are tiny molecules made up of RNA and related proteins that are responsible for protein synthesis.
Proteins are required for many cellular activities such as emergency repairs and chemical process control.
Ribosomes are found in the cytoplasm or connected to the endoplasmic reticulum.
Ribosomes have two primary functions: message decoding and peptide bond formation.
The ribosomal subunits are two huge ribonucleoprotein particles of variable size that house these two activities.
Each subunit is made up of one or more ribosomal RNAs as well as numerous ribosomal proteins.
Ribosomes communicate with the cell to produce proteins.
Thus, the correct option is A.

1. How does carbon enter the soil?
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground.
Answer:
Carbon enters the soil through the decomposition of organic material.
Explanation:
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. That’s why when humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

Put the following statements about a synapse in the correct order.
= Vesicles filled with neurotransmitters move to the end of the axonal terminal
= Neurotransmitters attach to the sodium channels on the dendrite.
= Action Potential reaches the Axonal terminal
= Sodium channels open
= Neurotransmitters are released into the synaptic cleft
= Sodium moves into the Dendrite
= Action potential travels through the dendrite
Answer:
Action Potential reaches the Axonal terminal
Vesicles filled with neurotransmitters move to the end of the axonal terminal
Neurotransmitters are released into the synaptic cleft
Neurotransmitters attach to the sodium channels on the dendrite.
Sodium channels open
Sodium moves into the Dendrite
Action potential travels through the dendrite
Explanation:
The process of transmission of action potential across a synapse ( a junction between two neurons) begins with the arrival of an action potential from the presynaptic neuron. The steps are given below:
Action Potential reaches the axonal terminal of the presynaptic neuron
Vesicles filled with neurotransmitters move to the end of the axonal terminal of the presynaptic neuron
Neurotransmitters are released into the synaptic cleft
Neurotransmitters attach to the sodium channels on the dendrite of the postsynaptic neuron
Sodium channels open
Sodium moves into the dendrite of the postsynaptic neuron.
Action potential travels through the dendrite towards an effector or another neuron.
