Euglenas are heterotrophic.
Hererophic (must consume food) and autotrophic (can make its own food).
Answer: Germline mutation
A germline mutation is a mutation in the fully developed germ cells (sperm and ovum). These defective mutated cells fuse to form zygote. The zygote rapidly produces all somatic and germline cells in the offsprings which are also mutated. Therefore, mutation is transmitted from parents to offsprings. Cystic fibrosis is a result of germline mutation. This disease is hereditary in nature passes from parents to the offsprings. If a child receives CFTR (cystic fibrosis transmembrane conductance regulator) mutated gene from both the parents than the child will be affected by the symptoms of this disease. If the child receives a single copy of CFTR gene from either of the parent than the child will be the carrier of disease.The mutated gene may be present in the germline cells of the parent or on all the body cells.
Answer:
Option (2).
Explanation:
Zygote is formed by the fusion of the male and female gamete during the process of sexual reproduction. The zygote undergoes further development inside the female womb.
The embryonic period starts from the third week after the conception. The important organs and structure development occur during the embryonic period. The formation of three germ layers occur in this period.
Thus, the correct answer is option (2)
Answer:
A
Explanation:
The thrifty gene hypothesis postulates that due to dietary scarcity during human evolution, people are prone to obesity by storing energy as fat, an ability to take advantage of rare periods of abundance and this is advantageous during times of food availability. individuals with greater adipose reserves would more likely survive famine. This tendency to store fat could lead to obesity.
FTO is an enzyme that is encoded in humans by FTO gene located on chromosome 16. Increase in this enzyme is associated with the regulation of energy intake but not feeding reward. Also, the set point theory indicates that bodies are meant to stay within a narrow weight range but it is susceptible to chnage overtime.
Answer:
Explanation:
The third-quarter moon, also known as the last quarter moon, rises around midnight and sets around noon. Crescent Waning From our vantage point, the Moon is nearly back to the point in its orbit where its dayside directly faces the Sun, and all we see is a thin curve
When you look at a waxing crescent moon, you see a thin fraction of the moon's illuminated side and a larger fraction of the moon's night side, which is submerged in the moon's own shadow. Earthshine on a waxing crescent moon
The Decline The Gibbous phase occurs when the illuminated portion of the Moon decreases from 99.9 percent to 50.1 percent. It begins shortly after the Full Moon and continues until the Third Quarter Moon. Waning refers to the fact that it is shrinking and becoming smaller, whereas gibbous refers to the oval-to-round shape.
Hope this helps you!
