You enter a small cottage in the middle of the woods. You find a purple liquid in a pot. The cottage also has a lot of science equipment lying around, including a triple beam balance. Luckily, you also find an alchemist’s journal that she has used to record her experimental data. You find a graduated cylinder. It weighs 25 g. You pour in 20 mL’s of the liquid. You measure the mass of the filled cylinder, and discover that it now weighs 65 g. What is the density of the liquid?
Answer:
ur first answer is 16,25 ur second answer is 32,500
Explanation:
25 g x 65 g= 1625 g 1625 g x 20 mls = 32,500 g ml
When neurons/nerves are cut, the cells cannot deliver neurotransmitters. Explain how this may affect the body:
Answer:
Nerve: When a nerve is cut, both the nerve and the insulation are broken. Injury to a nerve can stop the transmission of signals to and from the brain, preventing muscles from working and causing loss of feeling in the area supplied by that nerve.
Neuron: An injury to a neuron can stop the signals transmitted to and from the brain, causing muscles to not work properly or a loss of feeling in an injured area. Nerve injuries can impact the brain, the spinal cord, and peripheral nerves.

Superweeds: Due to new genetic engineering technology, scientists have been able to alter the DNA in corn, soybeans, and cotton to make them resistant to the chemical herbicides used to kill weeds. Consequently, millions of acres of United States farmland have been regularly sprayed with herbicides, leading to the development of a herbicide tolerance in weeds. Producers must now use larger amounts of herbicides and find new, stronger chemicals to fight off the herbicide-tolerant weeds.
What was the initial factor that led to the development of herbicide-resistant weeds?

examine the image shown here. These two species shown are pollinators and the flowering plant that they feed upon. Which statements accurately describe the interaction between these two groups?
A)Natural selection put pressures on the pollinator to increase its fitness over generations.
B)Heterozygote advantage provided a mechanism for species to become better fit for within their environment.
C)Convergent evolution caused the proboscis of the pollinator to mechanically fit with the flower of the other species.
D)The pollen of one species increased the mutation rate of the pollinator species so that they were more adapted to their flower.
E)Coevolution provided a mechanism for these two species to put selective pressures on each other to shape the pollinator structures.
Coevolution refers to the existing relationship between two species, and the selective pressures that each of them imposes on the other. These pressures result in both species evolving together in the same direction.
------------------------------------
When the interaction between two species is so strengthened that each population exerts a selective strength over the other one, simultaneous adjustments occur, resulting in Coevolution. Coevolution is the biological relationship existing between two or more species that interact and adapt to each other. Coevolution is the mechanism by which coadaptation can be explained. Coadaptation refers to reciprocal genetic changes in species that interact. This is due to the selective pressures that each of them imposes on the other. Coadaptation is what can be seen or observed.For coevolution to exist, there must be phenotypic variation and heritability. Coevolution can be specific or diffuse. Specific or strict coevolution involves two species in interaction in which the evolution of each one responds to selective pressures applied by the other species.
The correct option is E) Coevolution provided a mechanism for these two species to put selective pressures on each other to shape the pollinator structures.

How does soil affect the surface of the earth
The type of soil varies from place to place on our planet and can even vary from one place to another in your own backyard. Soil erosion, caused by wind and rain, can change land by wearing down mountains, creating valleys, making rivers appear and disappear.
A geneticist determines that the order of four genes on a specific chromosome is CABD because the recombination frequencies were 35% for C-D, 24% for A-D, 23% for B-D, and 10% for A-B. What has the geneticist constructed
Given what we know about recombination frequencies and their use cases, we can confirm that by displaying these results, the geneticist in question has constructed a linkage map.
A linkage map is a tool used by geneticists. It displays the likelihood that a sequence of DNA will be passed on to the offspring of that cell during meiosis. The recombination frequencies can tell us the order for a DNA sequence due to the fact that the farther away the two nucleotides are from one another, the higher the recombination frequency, such is the case with C-D at 35%.

A.
18
B.
36
C.
48
D.
72
Answer:
C. 48
Explanation:
Simple thing to bear in mind; The number of neutrons is equal to the Atomic number - the Mass number. Because the Atomic number tells you the number of Protons, whilst the mass number tells you the number of both PROTONS and NEUTRONS. So 84 - 36 is 48. You have 48 neutrons

What are the characteristics of producers?Producers are organisms that produce food for themselves and other organisms. They use energy and simple inorganic molecules to make organic compounds. The stability of producers is vital to ecosystems because all organisms need organic molecules.
Producers, also called autotrophs, include plants, bacteria, and algae. Plants get energy from the sun and turn it into food, a sugar called glucose. This process is called photosynthesis.
Producers are organisms that can produce their own food. They usually include green plants. They trap the energy from the sun and use it to make food by the process of photosynthesis.

THE WORLD WITH A THOUSAND MOONS
CHAPTER 1: Thrill Cruise
By Edmond Hamilton
Lance Kenniston felt the cold realization of failure as he came out of the building into the sharp chill of the Martian night. He stood for a moment, his lean, drawn face haggard in the light of the two hurtling moons.
He looked hopelessly across the dark spaceport. It was a large one, for this ancient town of Syrtis was the main port of Mars. The forked light of the flying moons showed many ships docked on the tarmac—a big liner, several freighters, a small, shining cruiser and other small craft. And for lack of one of those ships, his hopes were ruined!
A squat, brawny figure in shapeless space-jacket came to Kenniston's side. It was Holk Or, the Jovian who had been waiting for him.
"What luck?" asked the Jovian in a rumbling whisper.
"It's hopeless," Kenniston answered heavily. "There isn't a small cruiser to be had at any price. The meteor-miners buy up all small ships here."
"The devil!" muttered Holk Or, dismayed. "What are we going to do? Go on to Earth and get a cruiser there?"
"We can't do that," Kenniston answered. "You know we've got to get back to that asteroid within two weeks. We've got to get a ship here."
Desperation made Kenniston's voice taut. His lean, hard face was bleak with knowledge of disastrous failure.
The big Jovian scratched his head. In the shifting moonlight his battered green face expressed ignorant perplexity as he stared across the busy spaceport.
"That shiny little cruiser there would be just the thing," Holk Or muttered, looking at the gleaming, torpedo-shaped craft nearby. "It would hold all the stuff we've got to take; and with robot controls we two could run it."
"We haven't a chance to get that craft," Kenniston told him. "I found out that it's under charter to a bunch of rich Earth youngsters who came out here in it for a pleasure cruise. A girl named Loring, heiress to Loring Radium, is the head of the party."
The Jovian swore. "Just the ship we need, and a lot of spoiled kids are using it for thrill-hunting!"
Kenniston had an idea. "It might be," he said slowly, "that they're tired of the cruise by this time and would sell us the craft. I think I'll go up to the Terra Hotel and see this Loring girl."
"Sure, let's try it anyway," Holk Or agreed.
With the Jovian clumping along beside him, Kenniston made his way from the spaceport across the ancient Martian city.
