After Michelle went on vacation for two weeks, she came home to find her potted plants had turned brown and died. The soil was very dry. While Michelle was away, she kept the curtains and windows closed and did not have a neighbor come by to water her plants. Michelle now realizes that she will have to do things differently the next time she is away for several days if she wants to keep her plants alive. Why is it important for Michelle to make sure her plants have their needs meet while she is away?
A.
She needs to make sure the plant receives water, sunlight, and air. Plants need all components to make their own food.
B.
She needs to be sure to put plant food in the pot. Plants need to be feed because they do not make their own food.
C.
She needs to add a lot of water to the pot before leaving. Plants only need moist soil to make their own food.
D.
She needs to keep the curtains open or set the plant outside. Plants only need sunlight to make their own food.
Answer:
A
Explanation:
The explanation lies in the answer. Plants need all components to make their own food.
Answer:
The answer is A

A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns.
a. gene modification
b. artificial selection
A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns. This is called as gene modification.
What is gene modification?Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology.
Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.
For example, cornstarch can be made with GMO corn and sugar can be made with GMO sugar beets. Corn: Corn is the most commonly grown crop in the United States, and most of it is GMO. Most GMO corn is created to resist insect pests or tolerate herbicides.
Therefore, A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns. This is called as gene modification.

1. write a sentence that describes how the food changes in the stomach.
2. write a sentence that describes how the food changes in the small intestine.
3. explain what happens to digested food in the small intestine
4. write a sentence that describes what happens to digested food in the cell.
Answer:1.Once filled with food, the stomach grinds and churns the food to break it down into small particles. It then pushes the small particles of food into the first part of the small intestine, called the duodenum. The small intestine is where most of the digestion and absorption of our food takes place.2.The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.3.The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.4.The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.

How do you think the formation of fossils in sedimentary rock disrupts or alters the process of sedimentary rock formation? In other words, how does the formation of a fossil fit into the process of sedimentary rock formation? Defend your answer.
Answer:
I can't help sorry
Explanation:
Answer:
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
