ASAP!!!A scientist designed an experiment to test where a plant's matter came from. She
measured the starting mass of a willow tree, the soil, and the container. After five
years, she repeated the measurements and observed that the tree gained 74 kg (164
lbs) but the soil had not changed much at all (only lost 57 g, approximately 0.12 lbs).
1. Use evidence, from the results, to explain that the idea that the mass of a tree
comes from the soil, is incorrect. 2 points
2. Why is it incorrect to say that the tree's mass comes from sunlight? 1 point
3. If the mass of the tree does not come from the soil or sunlight, explain the trees
increase in mass. 2 points
Answers
Explanation:
The fact that the soil did not change significantly after five years, while the tree gained 74 kg, suggests that the tree's mass did not come from the soil alone. If the tree had gained all its mass from the soil, the soil would have lost an equivalent amount of mass, which did not occur. Therefore, this evidence suggests that the mass of a tree does not come solely from the soil.
While sunlight is necessary for photosynthesis, which allows the tree to produce glucose, the mass of a tree does not come directly from sunlight. Rather, the tree uses the glucose produced during photosynthesis to build its own tissues, such as leaves, branches, and roots. Therefore, while sunlight is necessary for the tree to grow, it is not the source of the tree's mass.
The tree's increase in mass is primarily due to the process of photosynthesis. During photosynthesis, the tree uses energy from sunlight to convert carbon dioxide and water into glucose, which it then uses to build new tissues. Additionally, the tree may have also taken up nutrients, such as nitrogen and phosphorus, from the soil, which it incorporated into its tissues. However, it's important to note that the majority of the tree's mass comes from the carbon that it takes up during photosynthesis, rather than the nutrients in the soil.

characteristics of contaminated water
Answers
Contaminated water is a type of water that is harmful to human beings due to the presence of harmful substances, pollutants, or impurities that make the water unsafe for drinking or other household uses. The characteristics of contaminated water can be identified through various indicators, which can either be physical, biological or chemical.
Physical indicators are visible and may include color, taste, and odor, while biological indicators are not visible and may include bacteria, viruses, and protozoa. Chemical indicators may include heavy metals, pesticides, and organic compounds, among others.
Physical Characteristics: Physical characteristics of contaminated water include cloudy or turbid appearance, unusual taste or odor, or discoloration of the water. The color may range from yellow to brown, blue to green, or even black.
Biological Characteristics: Biological characteristics of contaminated water include the presence of bacteria, viruses, or protozoa. These microorganisms can cause diseases such as diarrhea, typhoid, cholera, and dysentery.
Chemical Characteristics: Chemical characteristics of contaminated water include the presence of heavy metals such as lead, arsenic, or cadmium. Pesticides and fertilizers can also contaminate water and affect human health. Organic compounds like benzene and toluene can also be present in contaminated water, which can lead to health problems such as cancer and nerve damage.
Therefore, it is important to test water sources regularly to identify and monitor any contaminants that may be present. This can help prevent health problems associated with the use of contaminated water.

Answers
This is an example of exponential growth.
Exponential growth refers to a pattern of growth where the quantity or size of something increases at an accelerating rate over time.
In the given scenario, Brain has one son, two grandchildren, and three great-grandchildren.
Each generation is producing more offspring, resulting in a rapidly increasing number of descendants.
The progression from one generation to the next demonstrates exponential growth because each subsequent generation adds more individuals than the previous one.
As the generations continue, the number of descendants grows exponentially larger.
Exponential growth can be observed in various natural and human-made systems, such as population growth, compound interest, and the spread of infectious diseases.
In this case, the number of descendants in Brain's family tree follows an exponential pattern, as each new generation multiplies the number of offspring, leading to a significant growth rate.
Therefore, the example given aligns with the concept of exponential growth.

How come a person can only increase his/her oxygen levels in the body by only three to five percent when hyperventilating?
Answers
Answer:
Hyperventilating can only increase a person's oxygen levels in the body by only three to five percent because the body has a natural mechanism to regulate the levels of oxygen and carbon dioxide in the blood. When a person hyperventilates, they exhale more carbon dioxide than they inhale, which leads to a decrease in carbon dioxide in the blood. This decrease in carbon dioxide causes the blood vessels to constrict, which reduces the amount of oxygen that can be delivered to the body's tissues. This is why hyperventilating can only increase a person's oxygen levels in the body by a small amount.

Explain what, if any, is the issue facing DNA polymerase in regards to its 5’->3’ activity when replicating DNA.
Answers
Answer:
The two strands of DNA are replicated in different ways
Explanation:
DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).

How do ribosomes create a mutation & how is this mutation controlled?
Answers
Ribosomes do not directly create mutations, but cellular mechanisms such as DNA repair and checkpoints help control and minimize the occurrence of mutations.
Ribosomes themselves do not directly create mutations. Mutations, which are changes in DNA sequence, can occur due to errors during DNA replication or from external factors like radiation or certain chemicals. However, the cellular machinery, including ribosomes, plays a role in the control of mutations through various mechanisms. DNA repair mechanisms help identify and correct errors or damage in the DNA sequence, reducing the likelihood of mutations. Additionally, cellular checkpoints and regulatory processes monitor and control cell division, ensuring that accurate DNA replication and distribution occur, minimizing the inheritance of mutations to daughter cells.

The total cost f(x), in dollars, for renting a vacation house for x days is shown:
f(x) = 10 + 250x
Answers
The function f(x) = 10 + 250x represents the total cost, in dollars, for renting a vacation house for x days. In this case, f(10) represents the cost of renting the house for 10 days, which can be calculated as 10 + 250(10) = 2510 dollars. Option 4 is correct.
To find out what f(10) represents, we simply substitute 10 for x in the given function:
f(10) = 10 + 250(10)
f(10) = 10 + 2500
f(10) = 2510
This function can be used to calculate the total cost of renting the house for any number of days, making it a useful tool for budgeting and planning purposes. Hence option 4 is correct.

Answers
Answer:
I believe the answer is C. a DEXA scan because medical experts consider DEXA scans to be the most useful, easy, and inexpensive test for helping to diagnose osteoporosis.
Explanation:
The diagnostic procedures that would be best to diagnose osteoporosis is: (c) a DEXA scan.
A DEXA (Dual-energy X-ray absorptiometry) scan is a specialized type of X-ray that measures bone mineral density, providing valuable information about bone health and the risk of osteoporosis. DEXA scans are said to be the gold standard for the diagnosis.
Osteoporosis is a medical condition characterized by a progressive loss of bone density and strength, leading to increased bone fragility and a higher risk of fractures. In osteoporosis, bones become porous and less dense, making them more susceptible to fractures, even with minor falls or injuries. The condition is more common in postmenopausal women due to hormonal changes that occur after menopause.

SCENARIO #6 – Candy Connection Mr. Lehman wanted to know whether or not his students would do better on a quiz if he promised them candy. He went to the library and read several studies about the effect of giving food to lab animals. He found out that if animals were given food as a reward for doing something, they usually did better the more reward they were given. He guessed that the more candy that his students were promised, the better they would do on the quiz. He had all of his classes participate in the experiment. There were four groups in all. Each group had the same amount of boys and girls, they were all given the same quiz, they were all the same age, the same ability, and they were all from the same background. The first group was not promised any candy if they did well on the quiz. The second group was promised 1 candy bar if they did well on the quiz.

What are transcription and translation?Transcription and translation are two processes involved in protein synthesis.
Transcription occurs first in the nucleus. During this event, mRNA is synthesized by copying a segment of the DNA molecule. The template DNA strand is used to pair its nucleotides and grow the new mRNA strand.Translation occurs in the cytoplasm. During this event, the protein is grown by reading the mRNA codon sequence. tRNA, associated with rRNA, recognizes the codons and adds the correct amino acid to the new growing polypeptide.Transcription and Translation

What are ribosomes?
A ribosome works as a tiny device that produces proteins. Special proteins and nucleic acids make up ribosomes. The process of making proteins is centered on the TRANSLATION of knowledge and the LINKING of AMINO ACIDS. A ribosome is made up of two subunits that lock together to perform the following two tasks: (1) Translate information encoded in messenger ribonucleic acid (mRNA) from the cell nucleus; (2) Link together amino acids chosen and gathered from the cytoplasm by transfer ribonucleic acid (tRNA) (3) Export the synthesized polypeptide to the cytoplasm, where it will combine with other molecules to form a functional proteinOrganelle involved in transportation: ENDOPLASMIC RETICULUM
Similar to how a city's road network enables mobility within it, the endoplasmic reticulum is a network of tube-like passageways via which proteins from the ribosomes can be transported.
Endoplasmic reticulum is another name for it. There are two types: RER and SER. Rough ER and Smooth ER are abbreviations for respectively. Ribosomes are affixed to rough ER, aiding in the synthesis of proteins. Cells use ERs for a variety of purposes. One of their main jobs is to serve as a transport route. The endoplasmic reticulum membrane is used to transport secretory proteins, primarily glycoproteins.
Hence, endoplasmic reticulum is involved in transport and not the ribosomes
