The length of a string in yards is a function f(n) of the length n in inches. Write a function rule for this situation.

1 answer:

6 0

<span>The foot is a unit of length used in the stately and U.S. usual dimension systems, signifying 1/3 of a yard, and is divided into twelve inches. Then, when we convert 1 yard to inches, it will be 36 inches. So therefore, the answer is the right function rule is f (n) = 1/36n.</span>

One critical observation used by both lamarck and darwin in their research is

Ymorist [56]

One critical observation used by both Lamarck and Darwin in their research is about characteristics of inheritance. Although each claimed different sources of inheritance, they were in unison that in time, individuals acquire characteristics called inheritance. Lamarck believed that inheritance is passed from parents to offspring, while Darwin thought that it’s a product of natural selection.

In translation, the cell uses the genetic information contained in mRNA to make the proteins that carry out the cell's work.

stellarik [79]

Answer:

The correct option is d) UAG

Explanation:

Central dogma can be described as the process in which the transcription and translation occurs. The process by which mRNA is made from the DNA is called transcription and the process by which proteins are made by mRNA is called translation.

The first codon present on the DNA is TAG. The mRNA formed from this codon will be AUC. When this mRNA will travel from the nucleus to the cytoplam, the tRNA will bring the anticodons UAG for the first mRNA codon. Hence, the correct option is D.

Maggie's Plant Experiment In this exercise you will read the following scenario and identify the parts of the scientific method

ANTONII [103]

Answer:

Please find the identified steps of the scientific method below

Explanation:

A scientific method is a series of steps that aims at solving a problem. The steps in a scientific method include:

1. Making observation: In this experiment, Maggie observed when she read that some plants grow better if the soil is acidic. This is her observation that led to the scientific question: Do plants grow better in an acidic soil?

2. Formulating hypothesis: Hypothesis is a testable explanation to a problem. In this experiment, Maggie's hypothesis is; IF acid is added to the soil, THEN plants will grow better

3. Test hypothesis: the hypothesis is tested by conducting an experiment. In this case, Maggie places two geranium plants of the same size in two pots. Then she added a tablespoon of vinegar to one of the pots and allows the other grow normally without acid. The independent variable in this experiment is the vinegar added while the dependent variable is the height of the plants. The plant group with the vinegar is the experimental group while the plant group without vinegar is the control group. The constants of this experiment are same sunlight, same amount of water, same location etc.

4. Analyse data: The growth of the control and experimental plants were measured every week for five weeks by measuring their heights. The height (cm) of the plants with vinegar for the five weeks as as follows: 10.0, 12.4, 14.8, 18.0, 21.4 while the height in cm for the plants without vinegar for the five weeks is as follows: 10.0, 11.5, 13.0, 15.7, 17.8.

5. Conclusion: Based on the result, the plants exposed to vinegar grew better each week except week 1, which is the week they started. Hence, the hypothesis of this experiment will be ACCEPTED because the experiment proves it.

Stem cells renew tissues but are all lost in childhood.a) trueb) false

ValentinkaMS [17]

Answer:

False

Explanation:

Stem cells are different type of cells in human body that can develop into different other body cells like muscles cells or brain cells and they gave the capability to renew themselves through mitotic cell division.

Stem cells are not lost in childhood but can be use to treat diseases or infection, it can be use to grow new cells and replace damaged body cells.

Eukaryotic cells have a large complex cytoskeleton. Especially in animal cells, they are very large why is this? What is the dif

Klio2033 [76]

Answer:

Eukariotic cells are bigger and complex than bacteria. The difference between cystoskeleton of eukariotic and bacteria cells is the type of proetein in each one.

Explanation:

The cytoskeleton is composed mainly in arrays of protein filaments. Its function is to maintain the shape of the cell, maintain in place the organelles (such as mitochondria, nucleus, etc.) and the transport throughout the cell. Every cell has a cytoskeleton, eukaryotic, bacteria and archaea. Eukaryotic cells are bigger than bacteria and have more organelles in them to maintain in place, this is why cytoskeleton are bigger and complex. The bacteria are a single cell, simpler, with a few organelles, the cytoskeleton is more simple but important. The cytoskeleton is similar in both, the difference is the type of proteins in them. In bacteria are simple proteins, meanwhile, in eukaryotic are a complex protein.
