Jason avoids drinking milk because he thinks he is lactose intolerant so his diet is ‎inadequate in calcium. how can jason try to improve his calcium intake?

Calcium is a mineral that helps the body to build strong bones and teeth. It also helps in blood clotting. Inadequate calcium intake increases the rate of bone loss (osteoporosis), and high blood pressure. Calcium is present in certain foods such as dairy products.

Jason can try to improve his calcium intake by including dairy products such as milk, yogurt, and cheese in his meals. He can also drink calcium-fortified beverages such as almond, orange juice and soy milk. Also, taking a daily supplement which may be in capsules or tablets can improve his calcium intake.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.  

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
