Evolution Due to environmental factors, It may not look it, but, needles are leaves, they collect solar radiation to produce glucose through the process of photosynthesis, however, needles are, some would say, evolutionary superior to leaves. Needles themselves hold in more water due to their dense wax coating, they are very difficult for insects and other organisms to eat, one because of their structure, and two because of their acidity, they can catch sunlight all year long due to their winter resilience( they don't fall, during the winter), and they have less surface area for wind to catch, which leaves them better protected from wind than most deciduous trees, however the surface area can also pose a larger problem for less surface area means less sunlight interception, therefore more are needed to compete against regular leaves. But.. I Digress... Plant needles are 'PROBABLY' initially the result of evolution of narrow leaves due to climate or environmental factors.
Sry its so long got carried away! Hope this helps xD
Answer:
The correct answer is 327.78.
Explanation:
A mortality rate refers to the determination of the rate of the occurrences of deaths in a given population in the course of a particular time period. The formula for finding the mortality rate is:
Deaths taking place in a given time duration / the size of the populace among which the deaths have taken place × 10ⁿ
The given population of the country is 250 million
The number of individuals died due to a certain disease is 819450
Thus, the mortality rate per 100000 can be calculated as:
819450 / 250000000 × 100000 = 327.78 deaths per 100,000 people.

Answer:
<h2>Car</h2>
Explanation:
Carbon dioxide is a type of colorless gas that is present in the atmosphere in a very trace amount. This gas plays an important role in the process of photosynthesis that occurs in green plants. There are many sources that increase the percentage of carbon dioxide in the atmosphere that has an adverse effect on nature and causes global warming. Car, trucks and many other machines are responsible for the production of carbon dioxide gases directly or indirectly.
Answer:
mitosis
Explanation:
<em>Mitosis produces daughter cells that are basically replicas to their parent cells. As the daughter cells duplicates itself, it has make sure the chromosomes were split equally.</em>
