Answer: A. Genotype: 1/2 Yy; 1/2 yy. Phenotype: 1/2 Yellow; 1/2 Green.
Explanation: The answer lies in Punnett´s Square. A visual representation of Mendelian inheritance. Dominant genes always express when an organism presents them. Recessive genes express when both alleles contain the recessive gene. A heterozygote contains different alleles for the same gene (Yy). A homozygote contains the same alleles for the same gene (YY/yy), which can be a Dominant (YY) or Recessive (yy) Homozygote.
y | y
Y Yy | Yy
y yy | yy
Answer:
Sternocleidomastoid is the muscle which when when contracted unilaterally, will produce lateral bend of the spine
Explanation:
Sternocleidomastoid muscle is responsible for the turning of neck and its nodding. It consists of long muscles that are able to connect the three process of temporal bones i.e sternum, clavicle, and mastoid. Thus, this muscle can bend the spine laterally.
The correct answer would be the second option. The abnormal development or growth of the cells that make up the inner lining of the cervix is known as cervical dysplasia. It is a pre-cancerous condition that involves an abnormal growth of cells in the lining of the endocervical canal which is the opening between the vagina and the uterus. A very common cause of developing this is the virus HPV or the human papillomavirus. It can be transmitted sexually and has many strains. This condition can still be cured when it is detected early. Without treating it, cervical dysplasia would develop to cancer.<span />
Answer:
Since sea urchins are picky, they are used as indicator organisms in public aquariums to determine if the system is functioning properly. This is because they are very "picky" about water quality. If the water is contaminated, the sea urchins will be the first to show signs of stress, spines laying down or falling off. Do use an aquarium filter and do clean up the day after feeding. Any metal exposed to the seawater will corrode and poison the tank. A dying sea urchin will often spawn out and rot out, causing the others in the tank to spawn and die as welll.
