Susan has just moved into a new house. For some reason, she cannot get the grass to grow in her yard. She decides to grow small amounts of grass inside her house as part of an experiment. The first group of grass is exposed to a light intensity of 400. The second group is exposed to a light intensity of 1200.
Using the graph, which of the following should be expected from Susan’s two groups of plants?
Group of answer choices
The plants at a light intensity of 1200 will produce more oxygen than the plants at 400.
The plants at a light intensity of 1200 will perform only stage 1 of photosynthesis.

When he carried out his experiment, Nathan found that he had three small
beakers of the same size and two slightly larger ones. He decided that the
sizes were close enough to compare the boiling behavior of the liquids. Is he
correct? Why or why not?
O A. No, because the intermolecular forces will be different in different
containers.
B. Yes, because the rate of boiling will be the same no matter what
shape the container is.
C. Yes, because the surface area will be different, making up for the
change in shape.
D. No, because the area exposed to the surface will be different,
changing the rate of boiling.
I think it's either B or D
Explanation:
it really depends on how differently shaped the beakers are sorry if this doesn't help very much
Answer: D!

How does a papyrus plant get energy from the sun? Use your understanding of photosynthesis to answer this question.
Write your answer in one or more complete sentences.
The papyrus plant get energy from the Sun through the following processes
below:
The plant absorbs solar energy from the Sun with the aid of the green pigment known as chlorophyll.The absorbed solar energy is then converted into chemical energy through the reaction between Carbon dioxide and Water to form Oxygen and Glucose.The Glucose formed represents the chemical energy which the plant uses for its daily activities.Read more about Photosynthesis here https://brainly.com/question/19160081

Think of, and describe a situation when your frame of reference (your point of view) affected the way an object's motion appeared to you as you observed it moving.
Be sure to explain what was your frame of reference.
What was the frame of reference for other people in your scenario who may have had a different frame of reference from yours, and what did each person see?
reference refers to something that is not moving with respect to an observer that can be used to detect motion. But if they use objects outside the bus as their frame of reference, they can tell they are moving.

1. In what ways does an organism’s mode of reproduction impact the diversity of its offspring? (Asexual vs. Sexual)
Answer:
Asexual reproduction = An exact copy of the reproducer
Sexual reproduction = Genetic variation into the organism if a random mutation in the organism's DNA is transmitted to offspring.
Explanation:
Example of Asexual Reproduction diversity - A red apple has apple seeds. You plant the red apple seeds, and it grows up to be no different than the apple before it.
Sexual reproduction Example of diversity -Two parents are of different ethnicities. The female gets pregnant, but because of the different genetics from both of the parents, the child will inherit their genetics + some random mutation in the DNA.
This impacts the diversity of the offspring because it can be an exact copy of the reproducer (Asexual), or significantly different with some similarities if the mode of reproduction was sexual.
I really hope this helps you! Please tell me if it did or not. Good luck with your assignment/exam/quiz!
(OMG TYSM FOR BRAINLIEST!! :D)
Answer:
Sexual reproduction uses two organisms in order to create another organism (reproduce). The organisms' offspring will have different traits than it's parent organisms. For example, if the offspring's female parent organism has green eyes and it's male parent organism has brown eyes, the offspring will have either green or brown eyes. If it has green eyes, the trait is known as the dominate trait while the brown eye trait is known as the recessive trait (or vise versa).
During asexual reproduction an organism, quite literally, splits itself in two. Thus creating a literal clone of itself. There is no difference between the original organism and it's cloned offspring.

Which of the following statements is NOT true?
Solar energy emits more greenhouse gases than fossil fuels.
Solar energy is the most abundant energy resource on Earth.
Solar radiation regulates Earth's climate and weather systems.
Solar radiation heats up the Earth’s surface providing a living environment for humans
Solar energy is the most abundant resource of energy in earth. Solar energy is not a source of greenhouse gases and it is formed from burning fossil fuels. Thus, statement A is not true.
What is solar energy?Solar energy is the energy from sunlight the most abundant energy resource for earth. Sun is the nearest star to earth provide light and a living environment in earth.
Solar energy warm up the earth's surface and regulates earth's climate and weather system. It is due to the revolution of earth around sun we have different seasons as summer, winter, spring etc based on the distance of earth and sun.
Greenhouse gases are carbon dioxide, methane oxides of sulfur and nitrogen etc. These gases absorbs temperature intensely from the atmosphere and increases the warming or earth surface.
Greenhouse gases are mainly formed from industrial effluents, burning of fossil fuels etc. They are not emitted by solar energy. Hence the first statement is not true.

Ocean waves are just one example of waves that can be used to study the properties of waves. Other examples include the ringing of a bell and the impact of an earthquake.
Can you think of other examples?
Answer:
Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through. The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling.
