Answer:
the intensity of density dependent factors increase
Answer:
Because of the tilt of the earth on its axis. When the North Pole is tilted towards the Sun, the northern hemisphere experiences summer solstice. At this time, since the south Pole is tilted away from the Sun, the southern hemisphere experiences winter solstice.
That is why, When it is summer in the northern hemisphere, it is winter in the southern hemisphere. It's all because the Earth is tilted on its axis.
Answer:
The correct answer is A. Sexual reproduction produces a greater variation in offspring.
Explanation:
- B is wrong because in sexual reproduction there are two organisms involved who combine their DNA, therefore resulting in non-identical offsprings.
- C is wrong because sexual reproduction requires the two organisms involved to exchange DNA's whereas asexual reproduction involves only one organism which only copies it's own DNA for reproduction.
- D is wrong because there are no risks as genetic defects and no need to seek a mate or it is easier than sexual reproduction which results in lower risks for the parents in asexual reproduction.
- E is wrong because asexual production is a more efficient procedure and results in a faster growing population because there is no need to search a mate.
- The answer is A because in sexual reproduction, two different DNA's from both parents get combined resulting in more variation in offspring. In asexual reproduction, there is only one set of DNA which does not allow the gene's to mix, causing a less diverse offspring.
Answer:
Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
Answer:
A hurricane is a type of storm called a tropical cyclone, which forms over tropical or subtropical waters. ... When a storm's maximum sustained winds reach 74 mph, it is called a hurricane. The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating, or category, based on a hurricane's maximum sustained winds.
