Trace fossil because a trace fossil is a fossil of a footprint, trail, burrow, or other trace of an animal rather than of the animal itself.
Answer: The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape. Folded proteins are stabilized by thousands of non covalent bonds between amino acids.
Explanation:
Yes, an amniocentesis is necessary.
While both the woman and the husband may not exhibit sickle cell anemia, they could be carriers of the sickle cell recessive gene. If she is heterozygous for sickle cell allele, because of her father, and the man has no recessive gene, then the child has no chance of exhibiting the disease but has a 0.5 chance of being a carrier.
However, if the man is also a carrier, the child has a 0.25 probability of having sickle cell anemia.
The earth orbits the sun. Due to this fact, the northern and the southern hemisphere are tipped toward the sun at different times. Different climate zones fall under the southern and the northern hemisphere. There are many factors which affect the climate of a place and the most important one out of these factors is LATITUDE. Latitude refers to how far or close an area is to the north or the south of the equator. The latitude of a place determines the length and the intensity of sunlight that that place will experience. Thus, a place that is closer to the equator will continuously receive a lot of direct sunlight and such a place will have a warm climate.
