Answers

Answer:

The element is carbon

Explanation:

It has ability to catenate and it is a major constituent of all living matters

Carbon is the element that can form a wide variety of substances, including long chains. The correct option is C.

What is carbon?

Carbon has the chemical symbol C and the atomic number 6. It is nonmetallic and tetravalent, along with each atom releasing four electrons to form covalent bonds.  

It is in Periodic Group 14 of the periodic table. Carbon accounts for just approximately 0.025 percent of the Earth's crust.

Carbon's distinctive features make it an essential component of biological molecules.

Carbon forms covalent bonds with oxygen, hydrogen, and nitrogen to form the several molecules required for cellular function. Carbon's outermost shell contains four electrons and can form four bonds.

Many essential molecules in your body, such as proteins, DNA, RNA, sugars, and fats, are made up of carbon atoms.

Thus, the correct option is C.

which response is a result of geotropism?

a) flower being produced
b) growing bigger leaves
c) roots growing downwards
d) seeds germinating

Answers

Answer is C) roots growing downwards

The response that is a result of geotropism is roots growing downwards. The correct option is c.

What is geotropism?

Gravitropism is the coordinated process by which a plant grows in response to gravity acting on it. It is also found in fungi.

Gravity can be classified as either "artificial gravity" or "natural gravity." It is found in all higher and many lower plants, as well as other organisms.

Plant structures, such as roots, grow downward due to positive geotropism. Plants that grow upwards, such as shoots, exhibit negative geotropism.

Because roots grow in the direction of gravity, they exhibit positive gravitropism. Because plant shoots grow in the opposite direction of gravity, they exhibit negative gravitropism.

Gravity is detected by statocytes, which contain statoliths that sink inside the cell.

Thus, the correct option is c.

Do all genes have a simple dominant/recessive relationship between two alleles? What is an example of a human trait that does have
this relationship between its alleles?

Answers

Answer:

Genes come in different versions, otherwise known as alleles, with dominant alleles being expressed over recessive alleles (one stronger than the other in terms of traits and etc). Recessive alleles are only expressed when no dominant allele is present. Color of the eyes, for example is allele A is brown color eyes and B is blue color eyes, and assume that A is the dominant then that relationship will prove A to be the simple dominant and B the recessive.

Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones
to stimulate the growth of shoots.
How are gibberellins able to affect other parts of the plant?
F Gibberellins are absorbed through the stomata and attach to chloroplasts.
G Gibberellins are transported through vascular tissues to other parts of the plant.
H Gibberellins become concentrated within the tissues of the plant during mitosis.
J Gibberellins become modified once they infect healthy cells and are later released to infect
other cells.

Answers

Answer:

Gibberellins are transported through vascular tissues to other parts of the plant.

Explanation:

I just took the test.

Gibberellins are able to affect other plants through their transport through vascular tissues to other parts of the plant.

Gibberellins hormones are produced in the meristem of plants and they stimulate growth. They affect other plants through the plant's vascular system.

What is plants vascular system?

Plant vascular systems are conducting tissue that helps in the transport of materials such as water, minerals, organic compounds including hormones in plants and other nutrients.  

This vascular tissue allows for the movement of gibberellin to other parts of plants.

Therefore, Gibberellins are able to affect other plants through their transport through vascular tissues to other parts of the plant.

THE WORLD WITH A THOUSAND MOONSCHAPTER 1: Thrill CruiseBy Edmond HamiltonLance 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 tarmaca 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.Read the following line from the text:A girl named Loring, heiress to Loring Radium, is the head of the party.What can be inferred about Loring from this line?
