how does the placement of the mica sheet and the direction of light affect the growth of a plant?

Answers

Answer 1

Answer:

Explanation:

When the mica plate was inserted on the illuminated side, the plant did bend towards the light. Therefore, the chemical signal was a growth stimulant because the phototropic response involved faster cell elongation on the shaded side than on the illuminated side.

A particle of rain water has just reached the ocean. In what order will the particle now complete the following steps of the water cycle?

Answers

Evaporation will probably be the next step. The water cycle consists of a few steps. Most of which you should know. But yeah evaporation would most likely be next.

Answer:

evaporation - condensation - precipitation - surface runoff

Explanation:

For a water particle that has just reached the ocean, the correct order of the water cycle is as follows: evaporation (liquid water changes to water vapor) → condensation (water vapor changes to liquid water) → precipitation (water falls to the Earth's surface) → surface runoff (water travels along the surface of the Earth into a reservoir, such as an ocean). The water cycle is a continuous cycle with no strict beginning or end.

Plants like the stinging nettle seen here have sharp, needle-like hairs that inject a burning chemical into animals that touch the stems or leaves. These hairs are used for A) protection. B) reproduction. C) photosynthesis. D) attracting insects.

Answers

Answer:

A. Protection

Explanation:

These plants have this external protection system to protect them against being eaten by these animals.

In cases where these plants are approached to be eaten by these animals, these systems which in this case are these hairs tend to make an effort by discomforting the approaching animals.

The animals upon sensing this discomfort retreat from feasting on these plants which thus prolongs their lives and prevent them from being eaten by these animals

Should blue crab fishing in the Chesapeake Bay be banned?

Answers

(This is most likely an opinionated question but this is what I would say)

Blue crabs get their name from their blue-tinted claws and are very popular type of crab. Many people harvest these crabs for meat. The number of blue crabs has decreased in the Chesapeake Bay because of over- harvesting and changes to their habitat. (Then explain if you think it should be banned after knowing this information) if you don’t think it should be banned then you could talk about regulations and licensing for crab fishing, or if you think it should be banned you could explain the effects of habitat loss on the crabs.

An antibiotic label says to take it for fourteen days. If we stop taking the medication after ten days, what would most likely
happen to the bacteria in our body?
A The bacteria causes the human immune system to stop producing antibodies to fight disease.
B A population of bacteria resistant to the antibiotic appears.
The strain of bacteria allows the human immune system to build up resistance.
The bacteria builds up a resistance to all types of antibiotics, turning into a "superbug".

Answers

Answer:

B

Explanation:

This actually happened to me! Since you don't fully kill off all the bacteria, they will mutate and become resistant to the medication. The 14 days ensures that the bacteria will all be killed whereas 10 days allows the stronger organisms to grow and reproduce(where they typically are immune/build an immunity)

O D. Higher land temperatures in the tropics

Answers

Answer:

Higher ocean temperatures in the tropics

Explanation:

apex :)

Higher ocean temperatures in the tropics are linked to increased hurricane strength. Therefore, option (C) is correct.

What is hurricane strength?

Hurricane strength is a measure of the intensity of a tropical cyclone, which is a rotating storm system that forms over warm ocean waters in the tropics. The strength of a hurricane is measured using the Saffir-Simpson Hurricane Wind Scale, which ranks hurricanes from Category 1 (weakest) to Category 5 (strongest) based on their sustained wind speeds.

Hurricanes can cause significant damage due to their strong winds, heavy rainfall, storm surges, and flooding. The strength of a hurricane is influenced by a variety of factors, including warm ocean temperatures, low wind shear, and high humidity. As global temperatures continue to rise due to climate change, it is expected that hurricanes will become more frequent and more intense, which could have significant impacts on coastal communities and infrastructure.

What is the elephant getting when the bond is broken in sucrose?

Answers

Answer:

The elephant is getting Energy.

Explanation:

The elephant is getting Energy because sucrose is been hydrolysed and the bonds are broken down by enzyme sucrase isomaltase present in the intestine. Inches the bonds are broken, it is broken into glucose and fructose which is absorbed by the small intestine into the blood. The glucose serve as energy source or it is been stored as fly oven in the liver which is later broken down to glucose which is use for metabolic pathways to produce energy.

The elephant gets OXYGEN when the bond is broken in sucrose.

Sucrose is a disaccharide consisting of one glucose unit and one fructose unit, both units are linked by a glycosidic bond.

The hydrolysis of sucrose generates a 1:1 mixture of glucose and fructose.

The glycosidic bond can be exemplified by the central atom of oxygen that connects both monosaccharides in the sucrose molecule.

Sucrase is an enzyme that binds to sucrose and catalyzes its hydrolysis to produce glucose and fructose.

In conclusion, the elephant gets OXYGEN when the bond is broken in sucrose.
