1. food meaning their source food could no longer be there so they have to search for something else to eat in order for survival
2. weather meaning the weather of which that animal is used to has chnaged for ex.) in Antarctica the weather is getting warmer so the polar bears and pennguins can adapt or die
They compete for resources in the community
The answer would be: <span>A.50%
A child will get genetic material from both parents, half from the father and half from the mother. This is why the gamete cells (sperm/ovum) are made from meiosis and only have 50% of the original genetic material.
</span><span>In this case, the parent carries a deletion on one of the two homologous chromosomes. Since the gamete only has one of the chromosomes, half of the gamete of this parent would have the defective chromosome and the other half have a normal chromosome. So, the chance for the child to inherit the defective gene is 50%.</span>
<span>The correct answer is: dna fingerprinting makes use of coding sections of dna that consist of two to five bases repeated over and over again which looks for the number of times such a sequence is repeated.
RNA is a molecule responsible for encoding proteins.</span>
Explanation:
viruses are very small -- 100 times smaller than the average bacterium, so small that they can't be seen with an ordinary microscope. Viruses can only exert influence by invading a cell, because they're not cellular structures. They lack the ability to replicate on their own, so viruses are merely tiny packets of DNA or RNA genes enfolded in a protein coating, on the hunt for a cell they can dominate.
