which examples represent abiotic factors affecting biotic factors? Check all that apply
Answer:
ash from a volcanic eruption kills new plant growth.
warm water from a nuclear power plant causes overgrowth of algae.
a river floods and deposits tree pollen along its banks.
Explanation:
Ecosystem consist of biotic and abiotic elements. Biotic refers to all living organisms while abiotic refers to all non-living elements of the environment. Living organisms depends on abiotic factors such as light, temperature, water and soil etc for their growth and survival. In the above answer, Ash of volcano, warm water and rivers are abiotic elements while plant, algae and pollen are biotic elements.

In guinea pigs, the allele for short hair is dominant to long hair. A guinea pig with short hair is crossed to one that has long hair. Over a period of years, a scientist keeps records of the offspring and finds that 44 of them have short hair and 46 of them have long hair. Based on this data, what are the genotypes of the parents:
1. HH x hh
2. Hh x hh
3. HH x Hh
4. hh x hh
I would choose Option 2
about 50% chance that the dominance is in, but when it is, its dominant, of course.
no other Option can give you a 50% chance
in 1 its always there, in 3 as well, in 4 never
Which of the statements regarding the nitrogen cycle is true? a. Denitrification occurs when a nitrogen containing compound is produced from nitrogen in the soil. b. Atmospheric nitrogen is absorbed through the leaves of plants. c. Nitrogen fixation is the process atmospheric nitrogen is converted into biologically usable forms. d. Animals obtain nitrogen through the process of cellular respiration
Answer: Option C
Explanation:
The nitrogen cycle can be defined as the process by which the nitrogen is being recycled. The nitrogen is transferred from the atmosphere to the plants and then from plants to animals, human beings.
Then from animals and human beings it is again transferred into the soil and then atmosphere.
The nitrogen that is found in the sol is not in the usable form by the plants, nitrogen fixing bacteria converts it into usable form.

G Allowing only the cows that produce the most milk to reproduce
H Peppered moths choosing mates with darker colors
Answer:
B Giraffes developing longer necks over time
A non-poisonous snake mimics a poisonous snake
F Galapagos finches choosing mates with stronger and longer beaks
H Peppered moths choosing mates with darker colors
Explanation:
Hope this helps
The examples of natural selection are as follows:
Giraffes develop longer necks over time.A Non-poisonous snake mimics a poisonous snake.Galapagos finches choose mates with stronger and longer beaks.Peppered moths choose mates with darker colors.Thus, the correct options for this question are B, C, F, and H.
What is Natural selection?Natural selection may be defined as the methodology through which organisms that are better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. The concept of Natural selection was first proposed by Charles Darwin.
According to the question, due to the requirement of long necks in order to get food from longer trees, Giraffe develops longer necks. In order to protect themselves from predators, a non-poisonous snake mimics a poisonous snake.
On Galapagos island, if there were variations in the finches of the bird, they get a variety of food resources in order to get more nutrients and energy for survival and reproduction.
Therefore, the correct options for this question are B, C, F, and H.

There are the same amount of carbon atoms on Earth now as there were in the past, but there are more in the atmosphere ever before. What explanation do you have for this?
The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
