Explanation:

Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Describe what happens to these four substances during photosynthesis.

Answers

Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

During photo synthesis a plant takes in carbon dioxide and water and produces oxygen and glucose(sugar).

All of your body systems have to work together to keep you healthy. Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide.

Explanation: Communication among organ systems is controlled mainly by the autonomic nervous system and the endocrine system. The autonomic nervous system is the part of the nervous system that controls involuntary functions. For example, the autonomic nervous system controls heart rate, blood flow, and digestion.

5. What do scavengers do? Give an example of a scavenger.

Answers

Answer:

1.a. Omnivores, Carnivores, and Herbivores.

1.b. Foxes, Tigers, and Deer.

2.a. A photosynthetic organism (such as a green plant or a cyanobacterium) that utilizes energy from light to synthesize organic molecules Green plants that convert carbon dioxide into carbohydrates in the presence of sunlight are called photoautotrophs.

2.b. Maize Plant.

3. Chemoautotrophs made their food by themselves using the energy from the sun. This means that an ecosystem that depends on chemoautotrophs for food is dependent on sunlight for food and survival because chemoautotrophic organisms are the primary producers in that ecosystem.

4. Decomposers are organisms that break down dead plants or animals into the substances that plants need for growth.

5.a. They keep an ecosystem free of the bodies of dead animals, or carrion. Scavengers break down this organic material and recycle it into the ecosystem as nutrients.

What could you make or do to make sure your bean plants stay upright and don’t fall down?

Answers

Answer:

I got this off of g o o g l e

Explanation:

I put pairs of small fence posts (one on each side) down the row. I then tied twine to the fence post and ran it on either side of the plants. This keeps them from falling over to the side. If you plant thick enough they won't fall to the front or back.

Seedlings fail to emerge. Several possible causes: (1) Beans are a warm weather crop and seed may rot in soil less than 50° to 60° F. Delay planting until the soil has warmed; (2) Soil is heavy or crusted; seedlings may not be able to push through. Add aged compost to the planting bed; cover seed with light compost mulch; (3) Seed was sown too deep or not deep enough. Beans planted in spring 2 inches deep or more may rot and fail to germinate. Beans planted at the end of spring or in summer may dry out and die if sown less than 1 inch deep. Plant beans about 1 inch deep in early spring; 2 inches deep later in the season

The branches of the bronchial tree lead to different lobes in the lungs.

True or False

Use evidence form the web AND use your OWN words

Answers

Answer:

True

Explanation:

It is divided into three lobes and each lobe is supplied by one of the secondary bronchi. The left lung is longer and narrower than the right lung.

Together, the trachea and the two primary bronchi are referred to as the bronchial tree. At the end of the bronchial tree lie the alveolar ducts, the alveolar sacs, and the alveoli. The tubes that make up the bronchial tree perform the same function as the trachea: they distribute air to the lungs.

Estrogen and Progestrone harmone help in the thickening of the inner wall of the uterus i.e. endometrium layer,for the reception of fertilized eggs and their development.

Progestrone prepares the uterus for a fertilizef egg to implant.

The uterus lining sheds if no fertilization occured because the sperm passes through the uterus so.the lining of the uterus again starts to break down and shed ,and new mestural period begins

Explanation:

Hope this helps u!!


Estrogen :thickens the endometrium,inhibits the action of FSH & LH
Progesterone :thickens the endometrium ,inhibits the action of LSH&LH in the luteal phase and stimulated LH secretion in follicular phase

Uterus lining (endometrium ) thickens during the proliferative phase of the cycle due to progesterone,if there’s no pregnancy the level of progesterone and estrogen decreases (due to breakdown of corpus luteum ) hence resulting into degeneration of the endometrium (Ischemic phase )

What is the standard equation of a circle with center (-2,0) and radius 4? what is the answer to = 1 kung ako ang gagawa ng isang papel pananaliksik ang layunin kung ito ay From the Encyclopedia Britannica biography:Benjamin Solomon Carson was born on Sept. 18, 1951, in Detroit, Mich. His parents divorced when he was eight, and he lived with his mother and brother first in Boston and then back in Detroit. He was a poor academic student in elementary school until his mother began to limit his television watching and had him read two books a week and write book reports.In 2008, Pres. George W. Bush awarded Carson the Presidential Medal of Freedom. In 2009 a movie about Carson's life, Gifted Hands: The Ben Carson Story premiered on television. Carson was the author of an autobiography, Gifted Hands (1990), written with Cecil Murphey, as well as several motivational books.In 1983 Carson moved to Perth, Australia, to work as a chief neurosurgery resident at Sir Charles Gairdner Hospital. After a year spent gaining experience, he returned to Johns Hopkins, where he was named director of pediatric neurosurgery. There he earned a reputation for dealing with difficult cases using advanced surgical methods. In 1985 he performed his first successful hemispherectomy, a procedure that removes part of the brain in order to control chronic seizures. He also became known for his work separating conjoined twins, in 1987 completing the first successful separation of craniopagus twins (joined at the head).From the Academy of Achievement autobiographical interview:We had to stay in the house and read these books and our friends were outside and they were playing and they knew we couldn't come out. It seems like they would be making just that much more noise to torment us. But, I hated it for the first several weeks, but then all of a sudden, I started to enjoy it because we had no money, but between the covers of those books, I could go anyplace, I could be anybody, I could do anything. And, I began to learn how to use my imagination more because it doesn't really require a lot of imagination to watch television, but it does to read. You've got to take those letters and make them into words, and those words into sentences, and those sentences into concepts, and the more you do that, the more vivid your imagination becomes. And, I believe that's probably one of the reasons that you see that creative people tend to be readers, because they're exercising their mind.I was reading about people in laboratories, pouring chemicals from a beaker into a flask and watching the steam rise, and completing electrical circuits, and discovering galaxies, and looking at microcosms in the microscope, and I just acquired so much knowledge, and I had put myself into those settings and I saw myself differently than everybody else in my environment who just wanted to get out of school so they could get some cool clothes and a cool car. And, I was looking down the pike and seeing myself as a scientist or a physician or something of that nature, and that was one of the things that sort of carried me through much of the ridicule and some of the hardships that a person would have to go through coming from my environment and going to medical school.The thing that I am probably the most proud of is not all the medical accomplishments or honorary degrees or various boards and societies. I'm most proud of the 100,000-plus letters that I have from young people, throughout America and around the world, whose lives have been changed by reading one of my books, or seeing me on television, or an interview in a magazine, and recognizing that they have the ability to define their own lives. If that's the legacy that I leave, I'll be very happy.I was talking to a friend of mine, who was a cardiothoracic surgeon, who was the chief of the division, and I said, "You guys operate on the heart in babies, how do you keep them from exsanguinating" and he says, "Well, we put them in hypothermic arrest." I said, "Is there any reason that -- if we were doing a set of Siamese twins that were joined at the head -- that we couldn't put them into hypothermic arrest, at the appropriate time, when we're likely to lose a lot of blood?" and he said, "No." I said, "Wow, this is great." Then I said, "Why am I putting my time into this? I'm not going to see any Siamese twins." So I kind of forgot about it, and lo and behold, two months later, along came these doctors from Germany, presenting this case of Siamese twins. And, I was asked for my opinion, and I then began to explain the techniques that should be used, and how we would incorporate hypothermic arrest, and everybody said "Wow! That sounds like it might work." And, my colleagues and I, a few of us went over to Germany. We looked at the twins. We actually put in scalp expanders, and five months later we brought them over and did the operation, and lo and behold, it worked.
