Answer:
TRUE
First it flows from the sun to autotrophs, or producers. Then it flows from producers to consumers. Energy never flows backward from consumers to producers. When you draw a food chain, always begin with energy from the sun to a producer.
Explanation:
Energy flows through an ecosystem in a two-way direction.

How many poles does Jupiter’s magnetosphere have? a. 2 c. 8 b. 4 d. 9
Answer:
A. 2
Explanation:
I was wrong the first time, I wasn't thinking of jupiter for some reason. sorry!
Answer:
A. 2
Explanation:
Jupiter's magnetic field is quite different from that of all other known planets — it essentially has two magnetic south poles instead of just one, a new Nature study finds. Scientists analyzed Jupiter with NASA's Juno spacecraft, which reached the planet sometime in 2016.

Describe two types of evidence–other than the comparison of DNA sequences–that can be used to determine the phylogeny of organisms. Discuss one strength of each type of evidence you described.
Answer: Comparing the DNA sequence of the organisms can also tell you how closely related species they are. It can give you even more information since the original DNA is how the amino acid sequence of cytochromes is coded for.
Looking at embryonic development also helps you determine the phylogeny of organisms because a way an embryo develops can be very similar to the way another species develops but then both are full-grown they look very different and its tuff to explain how close they might be related

difference between speed and lvelocity in three point
Explanation:
(1)speed is scalar quantity
(1) velocity is vector quantity
(2)speed can never be negative or zero and it is always positive
(2) velocity can be negative or zero and it can be positive
(3)speed is time taken to travel a specific distance
(3) velocity is time taken to travel minimum distance from 1 point to other point
(4)speed=distance upon time
(4) velocity = displacement (minimum distance between 2 points ) upon time

Explain why heavy fertilizer runoff and algal blooms disrupt the equilibrium (balance) in an aquatic system.
A. Fertilizer runoff:
B. Algal blooms:
Answer:
A - Fertilizer runoff can cause micro-organisms such algae to bloom out of control. B - Algae blooms suffocate the ecosystem if there is too much.
Explanation:
A - Not all fertilizer nutrients is used in agricultural production and so some of it makes its way into the excess water and therefore runs into creeks and rivers. It is also toxic to many animals in high concentrations as well as more sensitive native plants.
B - Algae blooms take a lot of oxygen out of the water, therefore suffocating natural wildlife. The decay that results from such large blooms is also problematic and takes away oxygen. Many algae likes slow moving water with little flow and in these optimal conditions with excess nutrients (Nitrogen, Phosphorus, and Potassium, NPK are the main ones) cause it to become out of control

When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
Energy cell harvesting is impotant. Cells need energy so they can move from one place to another and ATP helps that. ATP is consiered "energy currency" of the cell and it's useful for storing egery and helping molecules/cells move around.
Protein to move against concentration gradient requires energy. Protons go trhough a protein channel called ATP synthase which helps them move out of the mitrochonrial matrix.
The phosphorylation of another molecule can assist a protein to transport molecules against their concentration gradient by energizing them.
PHOSPHORYLATION:
Phosphorylation is the process by which a phosphate group is added to another molecule. Adenosine triphosphate (ATP) loses a phosphate group to another molecule in the process of phosphorylation to energize the molecule. This is the process by which energy is released for use. Moving molecules against a concentration gradient requires energy input in form of ATP, hence, phosphorylation can assist a protein to transport molecules against their concentration gradient by energizing them.Learn more at: https://brainly.com/question/15967997?referrer=searchResults

5. Which of the following are enzymes?
1 point
Lipase
Lactose
Amylase
Xylase
Cellulose
Glucose
Fructase
Fructose
Lactase
NONE OF THESE!!!
Answer:
Lipases, Amylase, Lactase, and Cellulase. Did this Help?
Explanation:
Lipases – a group of enzymes that help digest fats in the gut.
Amylase – helps change starches into sugars. Amylase is found in saliva.
Maltase – also found in saliva; breaks the sugar maltose into glucose. Maltose is found in foods such as potatoes, pasta, and beer.
Trypsin – found in the small intestine, breaks proteins down into amino acids.
Lactase – also found in the small intestine, breaks lactose, the sugar in milk, into glucose and galactose.
Acetylcholinesterase – breaks down the neurotransmitter acetylcholine in nerves and muscles.
Helicase – unravels DNA.
DNA polymerase – synthesize DNA from deoxyribonucleotides.
Cellulase -- is any of several enzymes produced chiefly by fungi, bacteria, and protozoans
A student wants to find out if the green coloring in grass is a mixture of dyes. He uses a solvent to dissolve the green coloring from some grass. He then separates the solution of the green coloring from the remaining grass. Which of these methods is used to separate the solution of the green coloring from the remaining grass?Immersive Reader (1 Point) Boiling Evaporation Chromatography Filtration
Answer:
The correct answer is - filtration.
Explanation:
Filtration is the extracting the dissolved or suspended solids from a liquid or solvent passed from a substance with small pores, called filter, that separates the solid with a larger size than the pores of the filter. The liquid goes through the filter known as filtrate.
In the given case, the remaining grass can be separated from the solvent by the process of filtration. Pass the remaining grass with filtrate through the filter.
The correct answer is - filtration.
What do you think the similarities are Between baking a cake and rocks
Answer:
When the baking temperature reaches 300 degrees Fahrenheit, sugar undergoes what is known as a Maillard reaction, a chemical reaction between amino acids, proteins and reducing sugars. The result is browning, which forms the crust of many baked goods, such as bread and baking a rock will just heat it up
Explanation:
Do you think partial melting will occur if there is direct contact of hot molten rock in the Earth’s crust?
Answer:
As it moves toward the surface, and especially when it moves from the mantle into the lower crust, the hot magma interacts with the surrounding rock. This typically leads to partial melting of the surrounding rock because most such magmas are hotter than the melting temperature of crustal rock.
2. Which of these is not an ecological pyramid?
A. Pyramid of Energy
