Answer:
1. SnapDragon - incomplete dominance
2. Cows/chickens- multiple alleles
3. Blood type in humans - co-dominance
4. Skin and hair color - polygenic inheritance
Explanation:
1. Sometimes, the phenotypic expression of a recessive allele cannot be completely covered by that of the dominant allele. This is called incomplete dominance. Flowers of snapdragon and four'o clock plants are the example of such an event where the recessive allele for flower color, which is white is also expressed in heterozygous plants along with the dominant red color, producing pink flowers.
2. Multiple alleles determine the genetic traits of cows and chickens.
3. There are three alleles in humans that determine the blood type - dominant Ia and Ib for A and B type respectively, and recessive Io for O type. when in a heterozygous person, both dominant alleles are present, both are expressed phenotypically forming AB type blood. this is called Co-dominance.
4. Skin and hair color in humans is determined by multiple alleles present in different chromosomes. this is called polygenic inheritance.
Adenosine triphosphate is considered a high-energy compound. The energy of this compound is transferred to the cellular machinery by the conversion of ATP to ADP. Along with this conversion is the release of energy which is used by the cells. ATP contains an ordered carbon structure which is the backbone of the compound and also it contains the triphosphate part which is the most important region of the compound. These phosphorus groups are being connected by oxygen atoms and they have oxygen atoms on the side. These atoms of oxygen has a negative charge which would cause for them to repel and would want to be away from each other. Removing even just one would release about 7.3 kcal of energy per mole of ATP.
Answer:
Hypothalamus
Explanation:
The Hypothalamus is located below the cerebral cortex. It's involved with basic functions like eating, sex, temperature control, sleep, aggression. It's main function is to produce sex, growth and stress related hormones carried down axons to the pituitary gland. When carried out, it's then released into the bloodstream to activate and organize distant body systems.
Answer:
C
Explanation:
C is the most similar because unlike viruses, living things grow and develop, have a basic structure that IS based on cells, and don't require a host. So the only option here that is true for both living beings and viruses is that they both have a way to reproduce.
tropical depression, according to the NOAA. A well-defined band of storm clouds began to wrap around the north side of the storm's circulation center in the early morning hours of Aug. 24. With winds of about 40 mph (65 kph), the storm was named Tropical Storm Katrina. <span>By the time it made its way to southern Florida on Aug. 25, Katrina was a moderate Category 1 hurricane. While it caused some flooding and casualties — two people were killed — during its first landfall, it appeared to be just another hurricane in an active hurricane season. Katrina weakened after passing over Florida and was reclassified as a tropical storm.</span>
