Answer:
2.Biotic factors are dependent on abiotic factors for food and protection.
3.Abiotic factors affect the type and number of organisms that live in a particular ecosystem.
Explanation:
An ecosystem is an environment that contains both living and non-living parts that actively interacts together.
The living part of the ecosystem is the biotic factors and the non-living parts are the abiotic factors.
- The biotic components actively depends on the abiotic component for nourishment.
- This is exemplified through the process of photosynthesis.
- Also, the shelter of organisms are derived from the abiotic factors.
- The abiotic factors have significant impact on the type and number of organisms that live in an ecosystem.
The answer is "C) water exhibits cohesive behavior".
During sexual reproduction, 'Meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gametes the two gametes then randomly fuse to form a new organism.
Answer:
Let us consider the genes for black individual to be BB.
Let us consider the genes for bluish gray individuals to be BW.
The cross will be:
B W
B BB BW
B BB BW
The results show that there is a 50% probability that the offsprings produced will have black colour. There is also a 50% chance that the offsprings produced will have bluish graycolour.
<em>The genotypic ratio for black individual : bluish gray individual will be 2:2.</em>
<em>The phenotypic ratio for black individual : bluish gray individual will be 2:2</em>.
The given statement is True.
Sea corals are found deep inside the sea and oceans. They can survive in the shallow water. Deep sea corals can be found in groups or else can be found individually in water. They belong to phylum cnidaria and they live for thousands of years. They are found deep inside and if not disturbed in their habitat they can live long.
