Answer:
1. False
2. True
3.True
Explanation:1. Polar molecules have two regions but the regions are with a partial +tive charge and a partial -tive charge
2. Water is a polar molecule because of the partial +tive and partial -tive charge hence it dissolves polar solute(solute with ions)
3.The more electronegative region bonds with an electrophile to form a weak bond(Hydrogen bond)
The primary brain vesicles are the forebrain, midbrain and hindbrain. The forebrain is the largest of all the three. Hunger is controlled by the hypothalamus.
<h3>What is the hypothalamus?</h3>
Hypothalamus is a part of the forebrain and is situated below the thalamus region. It controls and regulated the ANS and pituitary activities. It majorly regulates thirst, body temperature, memory, homeostatic functions and hunger.b
It plays a crucial role in controlling the appetite, emotional responses, the release of hormones and physiological cycles.
The prefrontal cortex is the part of the forebrain, the amygdala is the part of the midbrain and the cerebellum is the part of the hindbrain.
Therefore, hunger is controlled by option B. hypothalamus.

Answer:
The correct answer will be option- to make exact copy of the DNA and pass on to the offspring
Explanation:
DNA replication is a complex process which produces the exact copy of the DNA which gets passed on to the generations. The process requires various enzymes and gains its energy from the ATP so is known as ATP dependent mechanism.
The process has to take place before the division of genetic material during cell division cycle so it takes place during S or synthesis phase of the interphase of the cell cycle.
Since DNA replication produces exact or replicated copies of the genome in organism therefore, to make an exact copy of the DNA and pass on to the offspring is the correct answer.
Explanation:
Maybe.. to provide nutrients of Soil and Water...
The answer is C.
A. There is no exchange of water between organisms.
B. A single organism is excreting fluid. This will then evaporate into the atmosphere. No exchange takes place.
C. An animal consuming an organism involves two organism that both contain water. One absorbs the other’s water through digestion.
D. A plant absorbs nutrients from the soil. This could also be correct as there are organisms in the soil losing water through decay. However those organisms aren’t identified in the statement. This means that C. is the best answer.
