The correct answers are 2. arid climate and 4. oil resources
The climate always causes environmental climate, especially arid one, while oil both extraction and production creates environmental problems.
Answer:By. skynesher / Getty Images. The dependent variable is the variable that is being measured or tested in an experiment. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured.Sep 29, 2019
Explanation:
Bacteria need an optimum temperature for their growth, so this is the reason why we might not see as much bacterial colonization of microbes from human saliva on plates cultured at 25 °C versus plates incubated at 37 °C.
Why do bacteria only grow at certain temperatures?
- The main justification for incubating bacterial cultures at various temperatures is that different temperatures favor the growth of particular bacteria.
- Most infections and typical ambient bacteria are classified as mesophiles, which thrive in temperatures between 20 and 40 degrees Celsius.
- An optimum temperature is required for the enzymes to show their activity, and for the division also many enzymes are involved in the process. So, the bacterial culture can be seen at a particular incubation temperature only.

Answer:
a big one could be chain effect causing more extinct species
Explanation:
This is based on my assumption that brown is dominant over blue.
Since both parent have parents who are homo_zygous recessive, this tells us that both parents will be hetero_zygous.
When you cross two hetero_zygous parents, it can produce these genotypic and phenotypic ratios:
<u>Genotypic</u>
BB : Bb : bb
1 : 2 : 1
<u>Phenotypic</u>
brown : blue
3 : 1
Therefore there is a 75% chance that they will produce a brown-eyed offspring.
