Answer:
1) respiration 2) photosynthesis.
Explanation:
The correct answer is option b, that is, circadian rhythms.
A roughly 24-hour cycle in the physiological procedures of living beings, comprising animals, plants, fungi, and cyanobacteria is known as a circadian rhythm. In a strict sense, circadian rhythms are produced endogenously, however, they can be modulated by external cues like temperature and sunlight.
The circadian rhythms can affect the release of the hormone, sleep-wake cycles, digestion and eating habits, the temperature of the body, and other essential functions of the body.
Answer:
True.
Explanation:
In genetics, genetic similarities indicate the actual species. It also helps to identify the relationship or similarities between different species.
A physical character or structure can't be a measurement process of classifying any species as related to other species.
Such as Chimps is 90% genetically similar to human, but they not identical in physical appearance.
So, at present, scientists use genetic similarities between species to help classify them as related species, rather than focusing on physical or structure of any species.
Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.
