Which of the following is the best example of a point source of water
pollution?
a. Storm water
b. Agricultural Runoff
c. Factory effluent
d. Residential posticide runoff
Answers
The BEST example of a point source of water pollution is factory effluent (Option c).
Water pollution refers to the contamination of water with pollutants. These substances (i.e., pollutants) convert water unusable to carry out different activities (e.g., drinking, cleaning, etc).
Water pollutants include, among others, herbicides, food processing waste, volatile compounds, heavy metals, organic pollutant microorganisms (e.g. bacteria, parasites), etc.
Factory effluents are well known to be harmful water pollutants for aquatic ecosystems.
In conclusion, the BEST example of a point source of water pollution is factory effluent (Option c).

How do biotic and abiotic factors affect the characteristics of an ecosystem
Answers

d

Answers
Answer:
D
Explanation:
after mitosis II the daughter cell will have half of the chromosomes the father cell has.
A cell containing 28 chromosomes undergoes mitosis and cell division, and then each daughter cell will contain 28 chromosomes too, as the mitosis is the equational division that is in option a.
What is the significance of mitosis?Mitosis is an essential process that plays a crucial role in the growth, repair, and other essential processes that occur in all living organisms, such as growth and repair by producing new cells to replace old or damaged ones, mitosis helps in development as it creates the vast number of cells needed to form the complex structures of the body and takes part in asexual reproduction.
Hence, a cell containing 28 chromosomes undergoes mitosis and cell division, and then each daughter cell will contain 28 chromosomes too, as the mitosis is the equational division that is in option a.

The leg muscles of a sprinter would differ from a marathon runner in that ________. The leg muscles of a sprinter would differ from a marathon runner in that ________. per gram, the sprinter's muscles would have more mitochondria than the marathon runner's muscles the marathon runner's muscles would have a greater rate of contraction than the sprinter's muscles per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles per gram, the sprinter's muscles would use more oxygen than the marathon runner's muscles
Answers
Answer:
The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.
Explanation:
Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.
Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.

Which of the following is the best representation of the limiting factors affecting the elk population in this ecosystem?
O Number of scavengers, number of wolves, number of scientists studying Yellowstone.
Number of scavengers, and harshness of winter
Number of wolves, and harshness of winter.
The elk have no limiting factors
Answers
Answer:
Number of wolves, and harshness of winter.
Explanation: I took the test
The combination of factors that is capable of limiting the population of elk in an ecosystem would be the number of wolves and the harshness of winter.
The limiting factors of a population are those factors that hinder the population of an organism from increasing unlimitedly. In other words, limiting factors hinder populations from reaching their biotic potentials.
Limiting factors can be density-dependent if they have correlations with the density of species or density-independent if they have no correlation with an organism's density.
Wolves generally prey on elks, so they limit the growth of elk's population in an ecosystem. A harsh winter will also limit the overall growth of the population of elk in an ecosystem.
Scavengers cannot be a limiting factor to elk's population because they only feed on carcasses.

1-What are some ways in which metamorphosis helps the animals that undergo it?
Answers
Answer:
During metamorphosis, they undergo a change in body chemistry that enables them to live in salt water. In biology, metamorphosis is the process by which an animal develops continually, after birth or hatching. This involves the change in body structure; both internal and external features, regulated by hormones. Metamorphosis is occasionally accompanied by changes in the animal’s behaviour, physiology and biochemistry.
Explanation:
During metamorphosis, they undergo a change in body chemistry that enables them to live in salt water. They change color during metamorphosis as well. The salmon must return to fresh water in order to spawn (breed). Fish that live in the ocean as adults but spawn in fresh water are anadromous. Lampreys go through a period of metamorphosis
Define these types of relationships (symbiosis).

b. commensalism-
c. parasitism -
d. predator/prey -
e. competition -
Answers
Answer:
mutualism -Both species benefit
commensalism- One species lives with, on, or in another species (the host). The host species neither benefits nor is harmed from the relationship. The species that lives on the host is benefited.
parasitism - One species (the parasite) lives with, on, or in a host species, at the expense of the host species. Unlike in predation, the host is not immediately killed by the parasite, though it may sicken and die over time.
predator/prey -One species (the predator) hunts and kills another species (the prey)
competition -The struggle among organisms for the same limited resources in an ecosystem
Explanation:
If these organisms were arranged in energy pyramid, which organism would have the least amount of total available energy in relation Insect, coyote, lizard or shrub
Answers
Answer:
The correct answer is - coyote
Explanation:
In this food chain like other food web or chain, the producer makes their food and are photosynthetic plants which are fed by primary consumers or herbivores. Secondary consumers prey on these primary consumers and top predators eat these secondary consumers. In energy pyramid, the producer has the highest amount of energy and its decreases with the tropic level as only 10 percent of total energy move to next trophic level.
In these organisms, shrubs are a producer with the highest amount of energy, and it decreases with insects (primary consumer), then lizards secondary consumer and least amount of energy in coyote.
