The correct option is A. creating buffer strips around the lake using land vegetation to trap fertilizer runoff and prevent it from reaching the water.

A buffer strip refers to an area of land maintained in permanent vegetation that helps to control air quality, soil quality, and water quality, along with other environmental problems, dealing primarily on land that is used in agriculture.

Buffer strips trap sediment, and enhance filtration of discharge organic substances  as phosphates and pesticides by slowing down surface runoff that could enter the local surface waters (here, lake).

Thus, buffer strips can be used prevent discharge of organic substances  into the lake that lead to increase in biological oxygen demand  water affecting  the stable lake ecosystem.

Answer:

1. The meaning of a diploid chromosome is a chromosome that has two complete pairs (sets) of chromosomes (from each parent).

2. Muscle cells, bone cells, blood cells, skin cells, and nerve cells are all diploid. (most cells are minus reproductive ones).

3. Haploid chromosomes are chromosomes that only has only a single set of chromosomes that don't have pairs.

4. Reproductive cells are haploid

7. A dog would have 39 pairs of chromosomes (hence the total 78 chromosomes).

8. A dog's reproductive cell would have half of the diploid cell because it is haploid so it would have 39 chromosomes.

10.The only haploid cell out of the 5 options is the ovum/sperm cell because they are the only reproductive cells (and reproductive cells are always haploid unless they combine to make a pair and form a zygote)

Answer:

Plant 4

Explanation:

Joshua had been giving his plants 1/2 cup two times a week. This is the control group, because it remains unchanged.

Answer:

This is an example of parasitism

Ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of Predation. Thus, option A is correct.

A predator is a creature that eats all or a portion of the body of its victim, which may be alive or recently deceased. Predators are distinguished from decomposers, such as fungus and bacteria, which break down the remaining remnants of dead species, by the phrase "living or recently killed."

We can confidently classify a lion as a predator if we witness it devouring a zebra. However, the zebra is included in the wide definition as well! Prey for a predator can include both plants and fungi as well as living things.

Additionally, a predator is not required to kill its victim. Instead, it can just remove a part of the prey's body and leave it alive, like a grazing cow or a bloodsucking mosquito. Herbivory is the term for a predator-prey situation in which an animal or insect eats a plant; herbi- stands for plant, and -vory implies eating.

Therefore the correct option is B.
