Prompt: You are a carbon atom and you have just been exhaled out of a deer. Describe
the journey that you have been on or describe your new adventures. You should include
at least 10 things that you have learned in Unit 4 (cellular respiration, photosynthesis,
carbon cycle, etc).
Answer:
Cell--vein--heart--lungs--- environment.
Explanation:
The carbon which is produced by the cells in the form of carbondioxide goes with the blood through the vein which carries deoxygenated blood to the heart. After reaching the heart, the heart pumps this carbonated blood to the lungs through pulmonary artery and there this carbon is removed and releases outside the body and oxygen is loaded in the blood. The product of respiration are the reactants of photosynthesis whereas the products of photosynthesis are the reactants of respiration. Photosynthesis occurs in only plants whereas respiration occurs in all types of organism. Carbon cycle is a type of cycle in which carbon moves from atmosphere to biosphere, lithosphere and then again to the atmosphere.
Which is larger, 40 centimeters or 670 millimeters?
Answer:
670 Millimeters
Explanation:
1 Millimeter = 0.1 Centimeter
670 millimetres is equal to 67 cm which is greater than 40 cm. So 670 mm is greater than 40 cm.
What is a millimetre?It is a unit of measurement for length/distance. It is a very small unit of measurement. It is a visible unit of measurement, unlike a micrometre which is smaller than a millimetre but measures things that are not visible to the unaided eye.
It is a part of the metric system commonly used in Science, Technology Engineering and Mathematics (STEM). A millimetre is measured as one-thousandth of a metre.
The word metre is derived from a Greek word which means measure. The metric system that is used internationally for the measurement of various quantities is based on decimals.
Like a millimetre is one-thousandth of a metre, a micrometre is one-millionth of a metre. A centimetre is one-hundredth of a meter and a quantity smaller than a micrometre called a nanometer is one-billionth of a meter.
Therefore, 670 mm is 67 cm which is greater than 40 cm.

The diagram below shows a microscopic view of the lower epidermis of a maple leaf. The cell indicated by the letter B is a guard cell. Guard cells are found on each side of the stomata.
Which of the following statements correctly describes how guard cells affect the physiological processes in a leaf?
A. Guard cells shrink to let in pollen for plant reproduction and swell to keep in oxygen.
B.Guard cells shrink to let in carbon dioxide for photosynthesis and swell to limit transpiration.
C. Guard cells shorten to let in light for photosynthesis and elongate to keep water from entering the cell.
D. Guard cells become rounder to let in oxygen for cellular respiration and flatten out to block the release of carbon dioxide.
Answer:
D is the answer of your quest.
Explanation:
D
The statement that correctly describes how guard cells affect the physiological processes in a leaf is as follows:
Guard cells shrink to let in carbon dioxide for photosynthesis and swell to limit transpiration.Thus, the correct option is B.
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and photosynthetic algae generally prepare their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
Guard cells generally mediate the opening and closure of stomata. With the help of this activity, they regulate the rate of transpiration. Guard cells swell up and open the stomata for the exchange of gases when the plant has an excess of water and other useless gases. These types of cells are generally identified by their kidney-shaped appearance that surrounds the stomata.
Therefore, the correct option for this question is B.

(WILL GIVE BRAINLIEST ONLY IF CORRECT!!) How is the dispersive model different from the semiconservative model of DNA replication?
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.
Answer:
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
Explanation: it helps to remember that dispersive means to disperse your DNA molecules! And semi conservative means you keep one of your old strands! Hope this helps!
Answer:
option 1 is correct
Explanation:
in dispersive, each strand of DNA has alternating fragments of old and new DNA while in the semiconservative each new double helix consists of one old and one new strand.

The sun is marked B. There is an arrow from the air above the clouds, marked C, towards the left tree. An arrow from a location close to the ground marked D points towards Dead Organisms, which is a label under the animal. An arrow marked E points from the right tree straight up to the clouds. An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory.Which of the following facts is best represented by the arrow pointing from G to C? The chemical energy present in fossil fuels is used to create new forms of energy used for photosynthesis. Energy is conserved because the chemical energy present in fossil fuels is used up completely during burning. The mechanical energy produced on burning fossil fuels is transformed into chemical energy stored in carbon dioxide. Energy is conserved because the mechanical energy produced on burning fossil fuels is less than the chemical energy formed.

When reading “This tree starts with our ancient ancestors and leads to many species of hominids that are now extinct, with humans at the tip of the only surviving branch,” what did that make you think about humans? Do you think this indicates that humans are the pinnacle of evolution? Are they? Explain.
Answer:
Yes, humans are the pinnacle of evolution.
Explanation:
Adaptability to the change environment by the human is the only reason for the survival of human beings as compared to other hominids. The human survival also occurs due to evolution that changes the physical structure of humans and they are able to survive in that environment condition in which no other hominids survives so we can say that humans are the pinnacle of evolution.

Answer:
Nondisjunction (during meiosis in gametogenesis)
Explanation:
This is meiosis because we can see germ cells present, and the chromosome number is halved (typically) by the end of the process. This is nondisjunction because the sister chromatids/chromosomes are failing to separate properly during cytokinesis, causing improper amount of chromosomes in the germ cells. So on the left you have nondisjunction during meiosis II, because you have two cells with the proper amount of chromosomes after the first division. And on the right you have nondisjunction during meiosis I, because you have one cell with no chromosomes after the first division. The steps are as follows: 1 - Meiosis, 2 - Meiosis II, 3 - Fertilization, and 4 - Zygote (creation of).
