Answer:
natural selection is the answer
Answer:
There are two alleles, the recessive yellow allele and the dominant brown allele. The female is hom0zygous recessive while the male is heterozygous, this means that half of their children will be hom0zygous recessive and be yellow. The other half will be brown and heterozygous, meaning they have a yellow allele and a brown allele. If the female mated with a hom0zygous dominant male, then all of their offspring will end up being heterozygous and brown.
Cladogram is a diagram that tells the relationships between different groups of taxa called “clades”. Cladogram gives phylogeny (evolutionary history) of the taxa. The organisms which share derived characteristics are grouped together while constructing a cladogram. Jelly fish is a cnidarian share common characteristics such as radial symmetry, simple tissues and no body organs with other members like corals and sea anemones.
Energy, the many types of Biomass. There are three levels, primary consumers, secondary consumers, and tertiary consumers. Lower level animals have a greater species biomass its because higher level consumers are limited by there number of biomass.
The dehydration is a very common problem seen in elderly individuals. At an elderly age, all the body functions are diminished, which lead to reduction in thirst and body's ability to obtain water. That is why, the elderly people are very susceptible to dehydration.
In order to remain healthy, a person must take 2.5- 4 litres of water per day. In males, the water is required more than females. So, for males, the adequate intake (AI) of water should be in between 3-4 litres per day.
