Samuel ate some vegetable soup. <u>Digestion</u> process is at work to allow Samuel to break down the soup so that his body will be able to produce energy.
<u>Option: D</u>
<u>Explanation:</u>
There are majorly four steps in food processing in human body, these are ingestion, digestion, absorption and elimination. There are six major phases covered by digestion: ingestion, acceleration, mechanical or physical digestion, chemical digestion, absorption and defecation. The first of these procedures, ingestion, relates to the absorption of food via the mouth into the food canal.
Digestive system allow the transformation of massive insoluble food molecules into small water-soluble food components to dissolve them into the watery plasma of the blood. Many smaller particles are ingested into the bloodstream in certain species through the small intestine.
The most critical phase is introduction
Fossil fuels:
Advantage: easier to find and transport
They generate thousands of jobs
Disadvantage: butning fossil fuels for the environment degrades it and contributes to global warming
Hydroelectric:
Advantage: Hydroelectric power can be created 24/7 indefinitely assuming that the body of water it is utilizing never runs dry. It is also another absolutely clean source of energy.
Disadvantage: The turbines and dams that are built on the rivers or streams interrupt the natural flow of the fish and other wildlife that lives in the area.
Solar energy:
Advantage: Solar power helps to slow/stop global warming. Global warming threatens the survival of human society, as well as the survival of countless species.
Disadvantage: the sun doesn't shine 24 hours a day ao it can supply you with energy at night
Answer:
Hypothalamic-pituitary-adrenal axis (HPA axis)
Explanation:
- The three-stage process describing the physiological changes that take place in the body when it is under stress is known as general adaptation syndrome (GAS).
- The model describing the three-stage process was given by the scientist Hans Selye.
- According to this model, the responses in the body that occur during stress is regulated by the Hypothalamic-pituitary-adrenal axis (HPA axis) where the brain senses the stress and then the signals travel from the hypothalamus to the pituitary and finally the body releases cortisol from adrenal glands that contributes to the various changes.
Answer: Phenotype ratio is two heterozygous round pea : two homozygous wrinkled pea
Probability of getting a wrinkled pea is 1/2
The number of flowers that are homozygous is 2
The probability of getting a round pea is 1/2
Genotype ratio = 2 Rr : 2 rr
Explanation: From the information provided, round pea R is dominant while wrinkled pea r is recessive. A monohybrid cross between a heterozygous round pea Rr and a homozygous wrinkled pea rr will produce four offsprings, two of which are heterozygous round pea Rr and the other two are homozygous wrinkled pea rr.
The genotype ratio is 2 Rr : 2 rr while the phenotype ratio is two heterozygous round pea : two homozygous wrinkled pea. Heterozygous round (Rr) peas will manifest outwardly as round pea because R is dominant while r is recessive.
Since two out of the four offsprings are homozygous wrinkled pea, therefore the probability of getting a wrinkled pea is 2/4 = 1/2. Also, two out of the four offsprings are heterozygous round pea, therefore the probability of getting a round pea is 2/4 =1/2.
Since, only the two wrinkled peas are homozygous, therefore the number of flowers that are homozygous is 2
