Abiotic components of an ecosystem include everything except life which surrounds an individual and is not associated directly with the presence of other organisms these components are Material and Energy
Abiotic factors are further divided into three categories
1. Climatic factors
2. Topographic factors
3. Edaphic factors
And in forest there are all these factors present!
Answer:
The correct answer is - brown heterozygous Bb and blue eye bb.
Explanation:
In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.
case1:
Parent 1 : bb
parent 2: BB
B B
b Bb Bb
b Bb Bb
there are 100% brown eye offspring so this is not the case
case 2:
Parent 1 : bb
parent 2: Bb
B b
b Bb bb
b Bb bb
here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.
Answer:
They grow towards the sunlight to be able to generate energy
Explanation:
They need to do photosynthesis
A cinder cone<span> or </span>scoria cone<span> is a steep </span>conical hill<span> of loose </span>pyroclastic<span> fragments, such as either volcanic clinkers, cinders, volcanic ash, or </span>scoria<span> that has been built around a </span>volcanic vent.[1][2]<span> They consist of loose pyroclastic debris formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as either cinders, clinkers, or scoria around the vent to form a cone that often is beautifully symmetrical; with slopes between 30-40°; and a nearly circular ground plan. Most cinder cones have a bowl-shaped </span>crater<span> at the summit.</span><span>[1]
