A. Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.

Answers

Answer 1

Answer:

This question is incomplete, the complete part is: What is the independent variable in this experiment? A) The plant species B) The amount of water that each plant gets C) The amount of time D) The different types of light the plants were put under.

The answer is D

Explanation:

In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light. Hence, the INDEPENDENT VARIABLE is the DIFFERENT TYPES OF LIGHT THE PLANT WERE PUT UNDER.

Distinguish between:
Bat and Dove​

Answers

Answer and Explanation:

Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.

Their wings skeleton have the shape of finger/hands like a human.

Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.

#teamtrees #WAP (Water And Plant)

Answer:

Doves have beaks and no teeth, whereas bats have jaw bones with sharp teeth. Although they both fly, Dove and bats feature different structures that allow them to take flight. Doves have rigid, feathered wings that they flap completely in order to fly.

Which statement illustrates bias in scientific research?(1 point)

A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.

B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.

C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.

D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.

Answers

Answer:

D

Explanation:

The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)

In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:

The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interest

Scientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.

According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.

lV. Nutrients are made available to the body's cells

A. l and ll
B. ll and lll

The question above is asking for the "function" of the Digestive System. Function refers to how the digestive system actually works.

I is not related to the function of the digestive system. It only describes the "esophagus."

II is called the "Peristalsis." This is one of the functions of the digestive system. This allows the food to move down the GI tract.

III is part of the process called "Segmentation." This is one of the functions of the digestive system. The increase surface area of the microvilli expands 25 times and this allows greater absorption of food.

IV is not related to the function of the digestive system.

Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?​

Answers

When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.

What we know about vein valves.

There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.

Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.

Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

Answers

Answer:

I'm pretty sure its c

Explanation:

Warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.

What are topical waters?

Topical waters are defined as water between the Tropic of Cancer (23.5° North latitude) and the Tropic of Capricorn (23.5° South latitude). In the Köppen climatic classification, a tropical climate is one in which the average monthly temperature is over 18°C. There is no winter season and there is more annual rainfall than annual evaporation.

A good illustration of this kind of fish is the goldfish. On the other hand, "tropical" or "warm water" fish require a water temperature that is optimal for their comfort and health. Although different species of fish have varying needs, tropical fish generally demand water that is between 76 and 80 degrees Fahrenheit (25 and 27 degrees Celsius).


Thus, warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.

how does increasing the size of the habitat affect carrying? explain your answer. recall the scenarios: 0-15 years, little land; 15-30 tears, moderate land;30-45 years, ample land

plzzz helpp ​
I meant years not tears

Answers

Answer:

so basically carrying capacity is "the amount of organisms a specific environment can support", so if the environment is increased, most likely, more space and food will be available, which means the environment can hold more organisms, causing the carrying capacity to increase

Explanation:

what I just said lol

Answer:

Increasing the habitat size will increase the carrying capacity. Carrying capacity is the maximum amount of organisms a habitat and its resources can carry. So if the habitat expands and more resources become available, the population would expand. As you can see for the first 15 years, when it was the little land, there was only about () rabbits, but as the land grew throughout the years, the rabbit population grew. 15-30 years with moderate land had around () rabbits, and the ample land in years 30-45 had around () rabbits, a little over two times the amount the little land had.

Mr. Ridley On the Friday before winter break, Mrs. Lyon was out sick with a cold. So, Mr. Ridley substituted for the day. Most of the students in Mrs. Lyon's class were normally well-behaved. However, with the anticipation of the winter break, they became a little wild. While Mr. Ridley was writing on the dry erase board, Margo threw a paper airplane at his back. The class giggled as Mr. Ridley spun around to see who had thrown the paper airplane. "Class! Throwing paper airplanes at a teacher is unacceptable and disrespectful. Who did that?" Mr. Ridley asked. The students kept their mouths closed and sat up straight in their chairs. No one volunteered any information. "Fine then, you will all stay in from recess until someone tells me who threw the airplane," Mr. Ridley said. Mercy wiggled in her seat. She wanted to tell the teacher who threw the airplane, but she was afraid that the other students would call her a tattle tale. Alan, the class clown, was thrilled that someone besides him had done something foolish. He would never tell. He would expect the same loyalty from his classmates. Margo felt nervous. She wanted to confess and apologize to Mr. Ridley, but she was afraid that she would receive a harsh punishment. She wondered how long her classmates would protect her. Jervis sat and drummed his fingers. He didn't see who threw the paper airplane, but he guessed that it had been Alan. He was tempted to raise his hand and tell the teacher that Alan was the responsible party, but he wasn't completely confident. He really wished that someone would tell who did it. It wasn't fair that the whole class was being punished for one person's mistake. Rosania was happy that the class wasn't going to recess. She had terrible allergies and wanted to stay inside. She hoped that no one would say a word until recess time was over. Mr. Ridley walked around the classroom looking at each student's face as he went by. He thought he detected sweat and shaking when he walked by Fred. He wondered if Fred was the culprit. However, Fred just needed to use the restroom but was afraid to ask. "Fred, you seem a bit anxious. What is it you want to tell me?" Mr. Ridley asked. "Nothing, sir. I-I need to use the restroom," Fred stammered. "No one is leaving this room until I find out who threw that airplane at me," Mr. Ridley said. Margo could not allow her classmates to suffer any longer. "It was me! I threw it! I'm sorry, Mr. Ridley," Margo said as she burst into tears. Mr. Ridley hated to see children cry. He rushed over to Margo and gently patted her back. "I forgive you. Don't cry," Mr. Ridley said. "I was just being silly. I didn't mean to disrespect you," Margo sniffled. "We will forget all about it. Let's enjoy the rest of our day together. Because you were honest, we will all play games for the rest of the day," Mr. Ridley announced.6In the passage, the author contrasts the points of view of the different characters by A. demonstrating the consequences of each character's actions.
