The force that pulls falling objects toward earth is called
Answer:
The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
DNA provides a very significant role in the formation and development of an organism.what is that role?
Answer:
The significant role that DNA provides is the organism's genetic information. It stores its information inside, and that's what makes up all the traits of the organism. All known cellular life contains DNA for this reason, and basically serves as long-term storage of information about the organism.
ILL GIVE BRAINLY PLZ HELP Fisherman at Reelfoot Lake, in Northwest Tennessee, noted a drop in the number of catfish. What is the most reasonable conclusion, based on the data provided?
A) The pH of the rain will not affect the fish that live in the lake.
B) The pH of the rain falling into the lake is of level that it is killing the adult fish.
C) The pH of the rain falling into the lake is of level that it is affecting fish reproduction.
D) The pH of the rain falling into the lake is of level that it is both affecting fish reproduction and killing adult fish.
Answer:
D, if you look at the acid rain it covers both death of fish and reproduction

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?
Answer:
75% red, 25% other color (brown?)
Explanation:
A cross between two heterozygous red eye flies (Rr x Rr)
R r
R RR Rr
r Rr rr
The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.
Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)
How do you know something is dead
Is this without equipment?
Depending on what organism you are talking about, animals that can be seen with the unaided eye you can tell that they are dead by studying their bodily movements such as the rise or falling of their chest.
Plants with the unaided eye, the best indicator is to take a branch or piece off and study the insides color, if it is green then mostly likely they are alive.
Now microscopic organisms are harder to say, it depends on what you are referring to.
I need the anwser soon!!Which two statements describe what happens to energy during cellular
respiration?
O A Chemical energy is transferred to molecules of ATP and used to
carry out fe processes.
B. Some thermal energy is transformed into chemical energy-
C. Some chemical energy is transformed into thermal energy
D. Light energy is transferred to molecules of ATP and used to carry
out te processes
Answer:
the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
