The question is in another language so, English translation for the given question is as follows:
It is made up mostly of water; different organic molecules, such as carbohydrates; and inorganic molecules, such as mineral salts. It carries out most of the chemical reactions of the synthesis of molecules and obtaining energy. To which of the following cell structures does the above description correspond?
a) Nucleus. b) Genetic material. c) Cytoplasm. d) Cell membrane.
Answer:
c) Cytoplasm
Explanation:
The Cytoplasm is defined as a thick solution filled inside each cell and all the organelles float in the cytoplasm.
The Cytoplasm is majorly made up of water, carbohydrates, salts, and proteins. Cytoplasm contains different molecules and enzymes that carries out most of the chemical reactions and obtain energy. Cytoplasm also helps in providing shape to the cell.
Hence, the correct option is c) Cytoplasm.
The correct answer is hypothalamus; autonomic.
The General Adaptation Syndrome (GAS) is the sequence of physiological processes which occur when we are exposed to a stressor. GAS is comprised of three stages which are the alarm, the resistance, and the exhaustion phase.
The first stage, known as the alarm phase, involves the fight or flight response, which is the natural reaction when under threat. A distress signal is sent by the amygdala to the hypothalamus, which in turn activates the sympathetic branch of the autonomous nervous system.
Answer: Because apples mature more quickly than hawthorn fruit.
Explanation:
Sympatric speciation can be defined as the formation(evolution) of new species from the previously surviving ancestral species while both continue to inhabit at the same place. This is because the one of the two organism there got better resources than other.
Here, the reason the maggot fly has been contributed to the incipient speciation because apple matures more quickly as compared to that of the hawthorn fruit.
The flies feeding on apple have been selected for the rapid development.
