In humans, blood type inheritance is an example ofa. predominance.
b. incomplete dominance.
c. codominance.
d. complete dominance.

Answers

Answer 1
Answer:

I would say the answer is: Co-dominance

When I was taking biology I learned that there are 3 types of alleles.


You have IA, IB, and little i. The little i means it is a recessive trait. IA and IB are co-dominant. There's a lot more gibberish language I could use.  

Good luck and hopefully this helped. If you need me to go into greater detail just let me know.

If a scientist wanted to compare the exact number of organisms at each trophic level within a desert ecosystem, which pyramid would he or she use?

Answers

If a scientist wanted to compare the exact number of organisms at each trophic level within a desert ecosystem, the pyramid he or she would use would be the pyramid of numbers. The pyramid of numbers presents the population of organisms (individually) in each trophic level in a certain ecosystem.

Explanation:

Select all the answers that apply.Geological evidence of the age of the earth includes _____.

radiometric dating of rocks
fossil evidence
comparative anatomy
molecular clocks
gradual processes of rock formation

Answers

Answer;

  • radiometric dating of rocks
  • fossil evidence
  • gradual processes of rock

Explanation;

Radiometric dating confirms that Earth is ancient and explains how extremely slow processes can result in major changes to Earth’s surface. Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place.

-The ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.
radiometric age dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples and
fossil evidence

When energy flows from one trophic level to the next higher level what always happens?

Answers

Answer:

When energy flows from one trophic level to the next trophic level most of the energy lost as heat in the process.

Explanation:

The food chain is transfer of energy in the form of food from one trophic level to next in an ecosystem.

Energy flows from at each trophic level when organism of higher level consumes organism of the lower level.

Energy flows at each trophic level by 10% Rule which states that only ten percent of the energy will be transferred on at each trophic because of the following reasons-

1. Energy is lost in the form of heat at each step

2. Only consumable energy by organisms is transferred at the trophic level.  

3. Energy is lost through different biological processes such as respiration.
Energy is always lost as heat or to carry out processes in the orgainsms as you go to higher tropic levels.
