Answer:
Fertilization Follows. During the spring of the female cone's second year, the male and female gametes are ready. The pollen grows a pollen tube, which enters a little hole in the ovule's skin near its basal end, called the micropyle. The tube enters the ovule, and the sperm goes down the tube and into the ovule.
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
This would be probably true if the assumption that all possible genotypic variations would be equally distributed (so we would have 25% HH, 25% hh and 2x 25 Hh). If this distribution would be true and Huntingtons disease really was a single gene dominant trait diesase, then yes, we could expect such a distribution in the population.
There are two types of population growth: exponetial growth and logistic growth
Smoking and drinking can cause major birth defects. It can also cause the baby to be very sick when it is born, and have a near death experience.
depending on the amount of intake, the baby could also be born addicted to either one. It is very dangerous to drink or smoke during the development of a child.
Hope this is helpful!:))))
