17, due to the gravitational forces and wind drag placed upon the arrow while it is in motion it will decrease the speed over a certain distance. Thus, resulting in the arrow to drop a little lower in height, hitting the bullseye.
Answer:
The correct answer is: B. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children.
Explanation:
- The inheritance of genes from the parents to the offspring is mediated by the germinal cells or sex cells or gametes of the parents.
- The genetic material present in the somatic cells of the parents are not transmitted to the offspring.
- In the given case, the man who develops lung cancer generates some tobacco smoke induced mutations in some of the cells of his lungs.
- The cells of the lungs are type up of somatic cells. Hence, any mutations in the genome of these cells will never be transmitted to the offspring.
- Therefore, the children of the man will never become prone to develop lung cancer due to development of mutations in the lung cells of the man.
- However, if the man has inherited any mutation from his parents which can increase the risk of development of lung cancer, then these mutations will be present in his germinal cells and also in some of his gametes.
- Now, if a child is born due to the fusion of the the maternal gamete with one of these mutated paternal gametes, there is an increased chance of developing lung cancer in the child, irrespective of the fact whether he is a smoker or a non-smoker.
Myocardial infarction, also known as heart attack to most people, is a result of an acute blockage of bloodflow to the heart. If a patient would ask the nurse why he/she is experiencing pain, it is best to tell the patient that chest pain or any discomfort in the arm, shoulder, neck, or back is caused by the decrease of blood flow to heart. Add to that, the nurse may inform the patient that people experiencing heart attacks may also feel shortness of breath, along with sweating, weakness, nausea, and fatigue. It is important to inform the patient about these symptoms so that he/she will be aware that these are common for people with myocardial infarction and that immediate medical attention is a must.
Red, green, and brown algae have accessory photosynthetic plastids containing different pigments than the chloroplasts.
<span>It is known that chlorophyll absorbs red light and reflects green. That's why plants containing chlorophyll are green. </span>At a depth of the sea where these algae live, there is no red light but different. Red, green, and brown algae have other pigments that can absorb that different light and which allow these algae to maximum use sunlight.
