Answer:
a. His father's mother lacks a widow's peak.
Explanation:
To find out if you are homozygous or heterozygous, you need to find out the genotype of your parents. This you do by looking at their phenotype, their grandparents, uncles. After that it's easy to find out if it's homo or heterozygous. Of course, this need not even be done when it is a characteristic determined by recessive alleles, but in the case of a characteristic determined by dominant alleles, such as widow's peak (W), we must visualize the characteristic in the individual's country.
Since the man, shown in the question above, has widow's peak, so that your child knows if he is homozygous or heterozygous, just look at whether the trait is present in this man's parents. If his mother doesn't have widow's peak, we automatically know that the man is heterozygous, and that was his father's estate. However, if this man's mother has widow's peak and his father does, then the man is homozygous.
Answer: Cant give a solid answer if theres no graph attached.
Explanation: My guess if it was a downward trend in population numbers with a downward trend in ice cap sizes or something, it would support global climate change because it shows the shrinkage of the population that is resulting from melting ice caps.
Answer:
It doesn't name the phases of mitosis, but leads us to believe they are shown.
Answer:
The sample most useful in identifying the person who committed the crime will be fingerprint. Fingerprints are the impression of finger ridges left on the surface of an entity or area in a crime scene. No two individuals can have same fingerprints. No two fingers of a same individual can produce same fingerprint. These are not found to be similar in identical twins. Fingerprints can be collected from porous and non--porous surfaces. These can be collected easily from crime scene. These fingerprints can be matched with specimens obtained from victims or offenders in order to establish the identity. The physical fingerprint analysis is more superior than DNA fingerprinting as in DNA fingerprinting the results obtained from twins could be similar but physical fingerprints cannot be similar because of different ridge characteristics. Therefore, valuable technique for identification of person who committed the crime.
Because the lower levels of the food chain have the most energy so more organisms can be sustained, but as you go up the food chain, less and less energy is transferred so less organisms can survive
