Answer:
Explanation: The reason why these two traits are linked is that the genes responsible for hair and eye color happen to be close together on the same chromosomes. When genes like these are close together, the traits tend to end up coming in pairs (blonde hair/blue eyes, etc.).
Answer: the heat
Explanation:
see a silicon dosent
obsorb as much heat as metal say if your coking something and you have a pan then the pan gets hot a silicon really absorb the heat as fast
Answer:Recessive traits
Explanation: Albinism is a reccessive traits whose effect have been suppressed by the dominant traits in the parents phenotype.
Complete dominance occurs when an allele A completely dominate over allele a in the genotype of an organism.
For the parents to have given birth to a non albino it means they are heterozgous dominant(Aa) and a cross between two heterozygous dominant parents will result in one homozgous non albino,2 heterozygous non-albino and 1 homozygous albino with the phenotypic ratio of 1AA 2Aa,1aa
Answer:
Cleavage is a process in which cell is divided into several parts without increasing in size. There are 4 stages of cleavage i. e. 2-cell, 4-cell, 8-cell and 16 cell stages. 2 cell embryo cleavage occurs after 30 hours of fertilization. 4 cell embryo cleavage occurs after 48 hours. 6 cell embryo cleavage occurs on third day of fertilization. 8 cell embryo cleavage occurs on fourth day of fertilization and more than 100 cells are formed.
Answer:
The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.
Explanation:
Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.
