Answer:
scientist Alfred Wegener and no it wasn't accepted .
Explanation:
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

Do plants with shallow roots or deep contain a greater amount of radioactive substances?
Answer:
yes
Explanation:
roots that are deep get to more radioactive material underneath the earth
It is correct that the roots that are deep contain a greater amount of radioactive substances.
What are radioactive substances?Radioactive substances are atoms that naturally decay. They have the ability to emit alpha particles, beta particles, and gamma radiation.
Because they cannot be turned off like X-ray sources, they are more difficult to control.
Radioactive substances emit three types of dangerous radiation: alpha particles, beta particles, and gamma rays.
A substance is said to be radioactive if it contains unstable nuclei and can naturally release energy by shedding high-speed charged particles in an attempt to achieve a stable state.
However apart from the heat produced by the planet's establishment, radioactive potassium, uranium, as well as thorium are presumed to be the three principal sources of heat in the Earth's interior.
Thus, it can be concluded that the deeper roots will encounter more radioactive substances.

Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn't occur?
Hello. You have not shown the model of meiosis to which the question refers, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
Crossing over is a genetic phenomenon that occurs when two sister chromatids are broken at some points and the pieces are exchanged between them. these exchanges cause the appearance of completely new gene sequences, which can completely affect the expression of stretches in the cells where the crossing over happened, since this cell will have a different gene sequence than the others.
As you may already know, chromosomes are formed by two filaments, called a chromatid. These filaments are united by the centromeros and the union of two filaments and a centromero is called sister chromatides.

Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time?
Answer:
Determine how many groups you will have.
Prepare ping-pong balls.
Collect egg cartons.
Prepare the egg cartons.
Prepare “energy tokens.”
Post signs in the classroom.
Prepare filled H20 and C02 “molecules.”
Explanation:
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
Answer:
This new model may better explain the elements required for photosynthesis to occur. Sunlight, water, and carbon dioxide are required for the plant to produce its own food. Someone who is unfamiliar with the process of photosynthesis must begin with the basics and then build on this knowledge.

The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration help to
release carbohydrates
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.
What is the significance of respiration and photosynthesis?The photosynthetic process is the one that can make oxygen as a product, and later that oxygen is used by plants and other animals in the process of respiration, which is essential for life as the cell makes energy in this process. Plants and other chloroplast-containing photosynthetic organisms, such as blue-green algae, phytoplanktons, etc., can produce oxygen, which is then used in respiration to power the cell's activities.
Hence, the oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.

Based on the MSW streams that you researched above (Salem, Wake County, and USA), what would be the most meaningful strategy to implement in an effort to reduce the waste streams. This is purposely left ambiguous to allow for you to creatively answer the question.
Answer:
Remove organic waste, Reduce packaging, eliminate bottled water, give food waste to animals.
Explanation:
Organic waste, Reduce packaging, eliminate bottled water, give food waste to animals are the some strategies to reduce the waste streams. The Organic waste in the water streams can be used as a fertilizer to the plants. The portion of Organic waste is large in the waste stream so its removal is good for the reduction in waste stream as well as for the crops. Avoid throwing packages and bottles in the waste water and reuse these packages and bottles through recycling process. Food waste that are thrown in the waste water can be used as feed to animals because there is a lot of nutrients present in it.

1. What processes create igneous rocks?
2. What processes create metamorphic rocks?
3. What processes create sedimentary rocks?
Answer:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
Sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
Explanation:
Answer:
1. Igneous rocks form when magma molten rocks cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.
2. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
3. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

6. Which of the following is NOT true of the excretory system? a. Kidneys remove waste from the blood b. Removes waste from sweating c. Excretes feces d. Excretes urine
Kidney waste from sweating is not true of the excretory system.
The correct answer is option B.
What does the excretory system do?The principal function of the urinary system is to maintain the volume and composition of body fluids within normal limits. One aspect of this function is to rid the body of waste products that accumulate as a result of cellular metabolism, and, because of this, it is sometimes referred to as the excretory system.
What are the parts of the excretory system and their functions?The primary excretory organs in the human body are the kidneys, ureters, and urinary bladder, involved with the creation and expulsion of urine. Through these organs, much of the nitrogenous waste of the body, especially urea, is expelled.
