How does altitude affect climate patterns in a region? Areas at high elevations have cooler temperatures. Air continues to warm as it rises to a higher elevation. Tropical regions do not have many differences in altitude. High-altitude areas have less variation in seasonal temperatures.

Answers

Answer:

A. Areas at high elevations have cooler temperatures.

Explanation:

Areas with high altitude or elevations have cooler temperatures because air molecules are less in the air at high elevation that decreases the gas pressure leading to low temperature.

Earth's surface absorbs heat and diffuses it into the atmosphere that warms up the earth's surface. Layers of the atmosphere in higher-altitude areas diffuses less heat and maintain the low temperature.

Hence, the correct option is "A. Areas at high elevations have cooler temperatures."

What is the question???????

A student wants to shorten the ripening time for tomato plants. He predicts that the more water the plants receive,the faster they will ripen. To test this prediction,he grows 20 tomato plants in a garden in full sunlight that has dry soil and 20 tomato plants in a garden with a shadier location where there is greater moisture content in the soil. He then records the time it takes for fruit to develop and ripen on the plants in each garden location. State a serious error the student made with the design of the experiment. State all the constants in the problem.

Answers

Answer:

Explanation:

The major problem with this experiment is that he should have had a constant variable (in the form of the surrounding temperature) for his groups. Meaning, he should have had both groups planted in full sunlight and/or a shadier location since his prediction was on water intake by the plant and not the surrounding temperature.

The independent variable here is the type of soil (moist and dry) used while the dependent variable here is the time it took the fruit to develop and ripen on the plants in each garden location.

NOTE:

Independent variable can be described as the variable that is not dependent on any variable in the course of an experiment. It is also changed by the researcher during the course of the experiment.

Dependent variable can be described as the variable that is been tested during the course of the experiment.

Which scenario breaks the law of segregation? a gamete contains the father’s allele the gametes produced each have 1 allele after meiosis II a gamete produced has 2 of the same alleles after meiosis II the gamete fertilized has the dominant trait

Answers

Answer:

The answer is c a gamete has two of the same alleles after meiosis 2

Explanation:

I took the test

The scenario that breaks the law of segregation is "a gamete produced has 2 of the same alleles after meiosis II".

LAW OF SEGREGATION:

The law of segregation as proposed by Gregor Mendel states that the alleles of gene will separate into gametes after meiotic division.

The separation occurs in such a way that each gamete have only one allele of a gene after meiosis. For example, if a gene Aa undergoes meiotic division, the law of segregation explains that each gamete will contain either A or a in an equal proportion.

Based on the law of segregation, two alleles of a gene cannot be present in each gamete after meiosis II.

Therefore, the scenario that breaks the law of segregation is "a gamete produced has 2 of the same alleles after meiosis II".
