<span>The answer is B. We require trees to breath. We would be stuck in an unfortunate situation without our woods. Trees expel carbon dioxide from the environment and discharge oxygen through a procedure called photosynthesis. Basically all creature life on Earth needs oxygen to inhale and woodlands assume a key part in the complex worldwide oxygen cycle.</span>
Answer:
Stratospheric ozone is considered “good” ozone because of this beneficial role. In contrast, ozone formed at Earth's surface in excess of natural amounts is considered “bad” ozone because it is harmful to humans, plants, and animals.Most ozone resides in the stratospheric ozone layer and a small percentage (about 10%) is distributed throughout the troposphere.
Answer:
(A) True
Explanation:
The sun is producting the electromagnetic radiation which is the primary energy source on Earth and the driver of the entire climate system.
In general the sun is the source of energy that drives all life on Earth. This energy governs the weather, ocean currents and the hydrological cycles.
Without the continuous influx of sunlight and heat, life on Earth would cease to exist. The sun sets off the hydrological cycle, causing it to constantly evaporate into the atmosphere, from which it falls back to Earth.
Answer:
The parent with the genotype Aa BB Cc dd can produce 4 different types of gametes.
Explanation:
<em>The law of independent assortment states that the alleles for a trait separate when gametes are formed. </em>
In the parent genotype Aa BB Cc dd, the allelic pairs with variation present are Aa and Cc. Therefore, the source of variation in the possible combinations during meiosis, largely arises from these 2 allelic pairs.
Independently assorting these pairs, we have ; A, a, B, B, C, c, d, d
The possible combinations therefore are:
