<span>A social consequence of global fuel dependence is B. increase in atmospheric pollution levels. The more people use fuel, the more they are going to destroy nature and the environment around them, as well as the air we breathe. The atmosphere is definitely affected by the overuse of fuel, which is obvious if you take global warming into consideration. </span>
There are small individual fibres in the muscles, known as musclular fibres or muscle fibers that iat the same time are formed by myofibrils.
The most common and accepted theory of how muscles contract is the sliding filament theory:
The theory says that neurons send signals to the muscle fibres, and, inside these, actin and myosin bind with each-other, contracting themselves using ATP as an energy source. That is a simple way of describing how muscle contraction occurs.
The image down below may help you understand the sliding filament concept a bit better.
Hope it helped,
Happy homework/ study/ exam!
Answer:
Growth rate = 0.01 per 1,000 population
Explanation:
Natality rate 0.015 per 1,000 population
Mortality rate 0.005 per 1,000 population
Growth rate = Natality rate - Mortality rate = 0.015 - 0.005 = 0.01 per 1,000 population
Both the natality rate and the mortality rate are useful to estimate the dynamics of a population. The natality rate (also known as birth rate) and the mortality value are equivalent to the number of births/deaths per capita, although in population demography it is most common to use both values per 1,000 population.
Answer:
<em>The correct option is D) homologous structures</em>
Explanation:
In evolutionary studies, a homologous structure can be described s a similar structure which is present in different species. This is because these spices might have a common ancestor in the past. For example, the forelimbs of humans and bat. They perform different functions but their structure is similar. They are also derived from the same embryonic origin. These similarities show that the bats and humans might have shared a common ancestor in the past.
Answer:
Carbon dioxide and oxygen can't pass through the cuticle, but move in and out of leaves through openings called stomata
