Yes because we use the sun light as a way to grow crops for one so no one would be getting any food and plant life would never grow and would die so we wouldn't be getting Air as well because trees and plants make oxygen for us
Answer:
c. The ratio of long to short fatty acid tails in the membrane phospholipids increases
e. There is an increase in the saturation state of the fatty acid tails of membrane phospholipids
Explanation:
In biological lipid membranes, the homeoviscosity refers to the process by which the membrane 'adapts' its lipid composition to maintain a proper fluidity. It is well known that the membrane's fluidity increases with increasing temperatures. In this regard, it is important to have into account two points. First, the length of the fatty acid tail alters the membrane's fluidity: shorter fatty acid tails increase fluidity, while longer fatty acid tails decrease it (because shorter tails establish fewer molecular interactions between fatty acids tails). Second, the degree of saturation (i.e., the number of bonds between the carbon atoms) of fatty acids tails also affects homeoviscosity. A higher saturated fatty acid content decreases the membrane's fluidity because saturated tails are arranged in order to maximize molecular interactions between fatty acids tails.
Answer:
A.Earth's early atmosphere lacked oxygen, which multicellular organisms need to break apart food
Explanation:
One important feature that led to the development of multicellular organisms was the rise of oxygen-producing photosynthetic bacteria. Prior to this development, the unicellular organisms (anaerobes) then present on Earth obtained energy from inorganic fuels.
However, with the presence of oxygen in the atmosphere, a shift was observed as organisms that could obtain energy from the reduction of energy became predominant. This unicellular aerobes later paved way for the evolution of multicellular aerobes.
C. Smaller societies rely more heavily on legislation and military forces.
Answer:
<em>A: Multiple genes contribute to human height</em>
Explanation:
What Mendel observed in pea plants is generally considered to be exceptions to what is obtainable in most living organisms. Instead of segregating and assorting independently, a lot phenotypic expressions are as a result of interaction of several genes on different loci (polygenic inheritance) while in some cases, multiple phenotypic expressions are controlled by a single gene.
Human height is a continuously varying character and has been studied to be controlled by multiple genes. In addition, the human height is often a result of complex interaction between genetics and the environment.
The correct answer is A.
