You have planted corn in a field with clay soil. The field is predominantly flat with a slight slope at one end where a creek borders the field. You notice that germination and growth is slowest in the flattest portion of the field. Conversely, you also notice that you received good germination and rapid growth on the slight hill which meets the creek. You wonder why there should be differences in growth and germination in different parts of the field. Is it due to the extra water near the creek? Is there something different about the soil in that portion of the field, or is it due to the difference in slope (north, south, east, and west). 1. What is your hypothesis for this problem? 2. Design an experiment to test the hypothesis you have written (make sure you include a procedure [step by step list of what you will do], an IV, a DV, treatments, trials, and constants).

Answers

Answer 1

Hypothesis: The soil in the flat part of the field has less fertility than the soil on the small hill.

Experiment:

The experiment will be carried out in a greenhouse, to promote a controlled environment and equal to all plants used in the treatment.

In this experiment, the influence of the difference in fertility of the soil samples, in the flat part of the land and in the most inclined part, in the germination and growth of corn plants will be tested.

Corn seeds of the same species will be selected. All seeds will be sanitized and will go through the same dormancy breaking process, so that all of them have their germination stimulated.

Vessels with a capacity of 30 kilos will be caught. These pots will be cleaned, sterilized and filled with the same amount of soil collected in the field and with two corn seeds. It will be used 10 pots with soil that was collected in the flat part of the land, 10 pots with soil from the sloping part of the land and 10 pots with fertilized substrate containing high levels of fertility.

The pots will be placed in a greenhouse and will be irrigated with distilled water, to avoid contamination by possible substances in the water.

The pots will remain in the greenhouse for 100 days, where the behavior of seeds and plants in each of them will be observed and noted. After this period, a comparison will be made between the vessels of each treatment, assessing the differences between them and reaching the conclusion whether the hypothesis is true or false.

Answer 2

Hypothesis: The soil in the flat part of the field has less fertility than the soil on the small hill.

Experiment:

The experiment will be carried out in a greenhouse , to promote a controlled environment and equal to all plants used in the treatment.

Procedure:

In this experiment, the influence of the difference in fertility of the soil samples, in the flat part of the land and in the most inclined part, in the germination and growth of corn plants will be tested.Corn seeds of the same species will be selected. We will choose containers with more capacity. These pots will be cleaned, sterilized and filled with the same amount of soil collected in the field and with two corn seeds. It will be used 10 pots with soil that was collected in the flat part of the land, 10 pots with soil from the sloping part of the land and 10 pots with fertilized substrate containing high levels of fertility.These pots will then be placed in a greenhouse and will be irrigated with distilled water, to avoid contamination by possible substances in the water.The pots will remain in the greenhouse for 100 days, where the behavior of seeds and plants in each of them will be observed and noted.

Thus after this experiment we can conclude that whether hypothesis matches with the experiment.

All proteins have amino acids as their building blocks. Even though there are only 20 amino acids, there are more than a million different proteins, and each works in a unique way. Which of the following conclusions about a protein's function is best supported by this information? (4 points)

Group of answer choices

The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.

The amino acids reproduce in different ways, and this allows them to form many different proteins, which in turn directs the protein's function.

The shape of a protein determines what amino acids it is made of and what types of reactions it can be used for, which in turn affects the protein's function.

The shape of a protein dictates when a protein will break apart into amino acids, which in turn affects the protein's function.

Answers

Answer:

The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.

Explanation:

There are many different combinations for amino acids to bind, and all of the different combinations have very different structures.

Additionally, the unique shapes of all proteins determine the exact function that they have.

These different shapes will also affect what molecules can bind to it.

The secondary structure of a polypeptide is produced by bonds between amino
acids.
Describe how.

Answers

The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.

The  secondary structure of a protein is generated by hydrogen bonds between atoms of the polypeptide backbone.

A hydrogen bond is an intramolecular attraction between a hydrogen atom in one molecule and an electronegative atom (e.g., oxygen) of another molecule.

The most common types of secondary structures in proteins are alpha helices and beta sheets.

In alpha helices, the carbonyl group of one amino acid is bonded to the amino group of another amino acid spaced four residues apart in the polypeptide chain.

In beta-sheets, different regions of the polypeptide line up next to each other, thereby these protein regions interact by hydrogen bonds.

In conclusion, the secondary structure of a protein is generated by hydrogen bonds between atoms of the polypeptide backbone.

What do you mean by Cell cycle?

The Cell cycle may be defined as the process a cell goes through each time it divides.

Interphase is the initial stage of any cell cycle which is the interval between the end of one mitotic or meiotic division and the beginning of another. It is the longest phase of the cell cycle as compared to the mitotic phase.

Therefore, the interphase stage occurs before mitosis. In this stage, extra sub-phases like G1, S, and G2 are produced various proteins necessary for divisions.
