A heron is affected by many factors in its environment. What distinguishes the biotic factors from the abiotic factors?
Answer: C. living and nonliving
Explanation:
A heron is affected by many factors in its environment. Living or non-living distinguishes the biotic factors from the abiotic factors. So, the correct option is (C).
What are Biotic and Abiotic factors ?Biotic Factors
The term biotic is composed of two terms: “bio” describes living organism and “ic” which explains like, combined they are called as living organisms. Therefore we can infer that all living organisms which exists on earth are called as biotic components. Such as Plants, animals, human beings, decomposers, yeast, insects, etc.
Biotic components interface to develop new generations i.e to reproduce new organisms to sustain stability in the food chain.
Abiotic Factor
Non-living things of an ecosystem are called abiotic factors. They play a crucial role in shaping ecosystems as both biotic and abiotic factors interaction is a must for the permanence of the ecosystem.
Examples of Abiotic Factors are air, weather, water, temperature, humidity, altitude, pH, level of soil, types of soil and more, water flow rate, water depth, etc.
Thus, a heron is affected by many factors in its environment. Living or non-living distinguishes the biotic factors from the abiotic factors. So, the correct option is (C).

Explanation:
a sample of dna contains 10% guanine. what is the percentage of the remaining nitrogenous bases?
Answer:
10% 40% 40%
Cytosine 10%, Thymine 40% and Adenine 40%
If the sample of DNA contains 10% guanine, the percentage of remaining nitrogenous bases are cytosine 10%, adenine 40%, and thymine 40%.
What is a Nitrogenous base?
A nitrogenous base may be defined as the nitrogenous compounds that form an important part of the nucleotides which are known as the building blocks of nucleic acids like DNA or RNA.
According to the question,
The concentration of guanine in DNA = 10%.
According to Chargaff's rule, the amount of guanine is equal to the amount of cytosine. So, the concentration of cytosine is also 10%.
Now, the remaining amount of nitrogenous base = 100-20 = 80%. This 80% is divided into adenine and thymine 40% each.
Therefore, the percentage of remaining nitrogenous bases are cytosine 10%, adenine 40%, and thymine 40%.

What would the seasons on Earth be like if its axis was tilted like Uranus
Answer:
If Earth’s axis was tilted like that of Uranus, the days and the seasons would be very different. On Earth only the poles have perpetual darkness during winter and perpetual daylight during summer. With an axial tilt like Uranus, the Equator and the Arctic / Antarctic circles are almost at the same latitude. With the axis of Earth tilted 90 degrees, the Sun would stay almost directly overhead for months at a time at the polar regions, there would be hardly any change between a day and a night. Basically you have a time period lasting months which is equivalent to the midday of current equatorial regions.

Bacteria add carbon to the carbon cycle by (1 point)
O being consumed by larger organisms, such as plankton.
O decomposing dead organisms.
exchanging carbon dioxide and oxygen gases
O performing photosynthesis.
Bacteria and the carbon cycle have an important link, to understand this link we need to know that.....
The carbon cycle
The carbon cycle is constituted by the absorption of carbon dioxide by plants in the process of photosynthesis. Half of this absorbed carbon is released into the atmosphere and the other half the plant uses to produce sugars (glucose). When ingesting plants, animals ingest carbon together for their organism, being released through respiration or its decomposition.
Bacteria add carbon to the carbon cycleFungi and bacteria are responsible for the decomposition of both
Animals and PlantsThey ingest part of this carbon, releasing it to the atmosphere and the soil.
With this information, we can say that bacteria add carbon to the carbon cycle by decomposing dead organisms.
Decomposers, such as bacteria, are extremely important, because without them the carbon cycle would not be complete.
