Answer:
Triploid
Explanation:
The process whereby gametes produced by different sexes of the same species of organism come together is called FERTILIZATION. A gamete is said to be HAPLOID (n) if it contains one set of chromosomes while it is DIPLOID (2n) if it contains two sets of chromosomes.
Hence, if an haploid (n) and diploid (2n) gamete unites, a zygote that is TRIPLOID (3n) emerges or forms. A triploid zygote will have three sets of chromosomes i.e. n + 2n = 3n.
Answer: Positive feedback loop
Explanation:
Even before the food reaches the stomach (before ingesting it), the glands of the stomach mucosa begin to release its gastric secretion. The main characteristic of this secretion is acidity, as measured by pH (one of the physiological variables).
This acidity is a result of the presence of hydrochloric acid, which is part of the secretion composition. In addition to it, water, pepsinogen (which will give rise to the enzyme pepsin) and the intrinsic factor. The acid has a function of the protection of the entire system by eliminating microorganisms. It is also responsible for the activation of pepsin (which only occurs with acid pH), the enzyme that digests proteins containing the amino acids leucine or phenylalanine or tryptophan or tyrosine.
The concept of Positive feedback loop states that the body tries to increase the value of a variable (acidity, in the case of pepsinogen) when it is below its optimal value (called a point adjustment) and decreases this value when it is above optimal.
Answer:
The first layer is the crust, a skin of rock covering the planet. The core that Lehman had found was the Earth's inner core. The core that Richard Oldem had discovered turned out to be the Earth's outer core.
Explanation:
Semen is the thick fluid that contains the sperm that is basic in nature, thus protecting it from the acidic nature of the vagina.
