Answer:
I think the answer is C
''Reusing plastic bags''
Explanation:
Removing carnivores from a forest has a great impact on a environment since the population of the herbivores will increases drastically and the dynamic equilibrium of the area will be greatly effected.
If we look at choice B '' Heating homes with fossil fuels'', this will also have a big impact on the earth since fossil fuels are non-renewable and take centuries to form. Heating homes with them will result in loss of fossil fuels.
Now let's look at choice D ''Adding heavy metals to the water supply''. Heavy metals are dangerous to the human health and even cause cancer. This will cause thousands of deaths and will also have a great impact on the global stability.
This leaves choice C ''Reusing plastic bags''. This will cause less pollution and less harm to wildlife but doesn't have any big threat to the global stability. As in changing the world population or causing deaths in large numbers.
so I think choice C is the answer
Metaphase
The second stage of mitosis. In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere.
Answer:
Greatly affect.
Explanation:
This modification to the sampling procedure greatly affect the results because timing of sampling is very important that can change the results of an experiment. The water quality of lake is different in different times of the day due to human activities. The quality of water is good in the morning when there are no or less activities of people as compared to afternoon when the human activities are very high so timing can greatly affect results of the experiment.
Answer:
The mutation will become more common in offspring and increase the genetic variability in the gene pool.
Explanation:
If the mutation is beneficial to the organism and this organism breeds its offspring may carry this gene, if it´s really beneficial and for example makes an organism to have more access to females the mutation may spread faster.
The only way for a mutation to spread to other organisms is reproduction (eukaryotes)
A mutation may also spread to other organisms in prokaryotes in which bacteria may take plasmids (DNA fragments) from the environment.
Adrenocorticotropic hormone (ACTH),controls the release of glucocorticoids from the adrenal cortex .
ACTH stimulates the adrenal cortex to produce glucocorticoids and adrenal androgens. Glucocorticoids, such as cortisol, function by maintaining blood glucose levels during fasting, preparing the body during physical and emotional stress, preventing inflammation, and suppressing the immune system.
Glucocorticoids are secreted by the middle region of the adrenal cortex. The principal glucocorticoid is cortisol, which increases blood glucose levels. The third group of steroids secreted by the adrenal cortex is the gonadocorticoids, or sex hormones. These are secreted by the innermost region.
