The lumper potatoes that were grown in Ireland during the 1800s were essentially clones of one another. They all had the same genetic makeup. So, when a potato blight disease began infecting the potatoes, it spread to all potatoes equally. How could greater genetic diversity have lessened the devastation of the potato blight?

Answers

Answer 1

The question has options that are given as below:

A. Some potatoes would be more likely to have a genetic resistance to the disease and survive. B. The potatoes would have been able to trade genes so that they could survive the disease. C. More of the potatoes would have been edible varieties. D. None of the potatoes would have been infected by the disease.

Answer:

The correct answer is - A. Some potatoes would be more likely to have a genetic resistance to the disease and survive.

Explanation:

Genetic resistance is the capability or ability of some individual organisms of a population or species have to adapt the environmental or genetic changes and survive while other organisms of species are not able to do the same.

In this case, some of the potatoes more likely to show genetic resistance to the disease and condition and survive from the devastation of the potato blight

Many small accessory bones, such as sesamoid bones, are not included in this count.

The axial skeleton, comprising the spine, chest and head, contains 80 bones. The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones. Infants are born with about 300 bones with most of it being cartilage, but will later fuse together and decrease over time to 206 bones.

Imagine that you are given 25 germinating pea seeds that have been placed in 5M hydrochloric acid for five minutes. You place these seeds after you rinse them off, in a respirometer at the end of the five minutes and collect data. Predict the rate of oxygen consumption for these seeds and explain your reasoning.

Answers

Answer:

In the respirometer, it will be present no significant values of oxygen from the respiration process. The acid can denature proteins in a non-functional shape.

Explanation:

The pH of the solution will be considerably low in order to the proteins to work normally. In this case, the polarization of sites in the protein will cause a completely denaturation.

A normal pH is essencial for the best working coefficient of enzymes an proteins in general as well as temperature.

Some examples of nonpolar molecules include fats, oils, and waxes. How do these substances interact with water?

Answers

Answer: Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.

Explanation: Nonpolar molecules do not dissolve easily in water. They are described as hydrophobic, or water fearing. When put into polar environments, such as water, nonpolar molecules stick together and form a tight membrane, preventing water from surrounding the molecule.

Answers

Answer:

Nonliving aspects of an ecosystem are known as (Abiotic)

Abiotic is the nonliving aspects or factors of an  ecosystem which is needed by the organism for its survival.

Abiotic is the non-living part of an ecosystem on which all the biotic factors depend. If one of the abiotic factor is eliminated or prevented from entering the ecosystem then all living organisms are adversely affected because all these organisms depend on that abiotic factor. Examples of abiotic factors are water, sunlight, oxygen, soil and temperature which is present in almost in all ecosystems.

Answers

Answer:

The correct option is d

Explanation:

Plasma membrane (or cell membrane) is a semipermeable or selectively permeable barrier that regulates what goes in and out of the cell by keeping toxic substances out of the cell while allowing nutrients, ions and some metabolic products inside the cell.

This membrane surrounds all the content/organelle inside (cytoplasm and nucleoplasm) of the cell.

What is runoff erosion?

Runoff erosion is a natural process that produces the transfer of water from fields to adjacent land.

The runoff may lead to erosion because the eroded material in the soil can be deposited a significant distance away.

This process (runoff related to erosion) occurs when there is more water or any other substance (for example, pesticides) than the land/soil can absorb.

Why is forensics important?

The criminal justice system cannot function without the contributions of forensic science. Forensic scientists collect evidence from crime scenes and other locations, assess that evidence, and then create objective conclusions based on their findings. These conclusions can either aid in the investigation and conviction of criminals or clear an innocent individual of any wrongdoing.

Studies of handwriting for forensic purposes are an essential component of the legal system. These examinations seek to ascertain whether or not handwritten documents can be traced to particular writers by making a comparison to known exemplars of that handwriting.
