Answer: Meiosis produces the sex cells, that is the gametes (sperm cells and eggs) that unite to form a zygote. Meiosis ensures that the gametes have have haploid chromosomes so that the resulting zygote from their fusion will have diploid chromosomes.
Explanation: Meiosis is a type of cell division in which a cell divides twice to produce four daughter cells each with the half the number of chromosomes as the parent cell. Without meiosis new gametes are not produced. Meiosis ensures that the chromosomes are evenly distributed among the daughter cells and that each daughter cell contains 23 chromosomes. A sperm cell with 23 chromosomes fuses with an egg with 23 chromosomes to form a zygote with 46 chromosomes. If meiosis does not occur, gametes with haploid chromosomes will not be produced, and if the gametes have diploid chromosomes because meiosis does not occur, sexual reproduction will be a disaster because when two diploid gametes fuse the resulting zygote with be abnormal.
The answer is a. True.
The photosynthesis occurs in leaves, which absorb sunlight. But the amount of absorbed sunlight by leaves depends on both the leaf surface area and intensity of life. So, t<span>he leaf surface area is just as important as the intensity of light in photosynthesis. But, if we take into consideration other leaves' functions, such as gas exchange, then the intensity of light has no effect on it. Thus, in that case, the leaf surface area is more </span><span>important than the intensity of light.</span>

sensory neuron
Sensory neurons are the neurons responsible for receiving the information from the environment or the stimuli. This sensory neurons pass the message thru interneurons and then to Central Nervous System (brain and spinal cord) which then sends the signal to the motor neuron.
The early signs of a heart attack occur in 50% of patients that have a heart attack according to the Society of Cardiovascular Patient Care. If the early symptoms are noticed the treatment can be administered to prevent damage to the heart as the most heart damages, 85% occur in the 2 hours following the attack.
Answer:
Behavior genetics.
Explanation:
Genetics may be defined as a branch of biology that studies the inheritance and variation of the inherited characters. Mendel is known as the father of the genetics.
Behavior genetics may be defined as the field of the scientific research that uses the genetic methods to investigate the behavioral differences in the individual. This genetics uses the limits of genetics and environmental impact on the individual's behavior.
Thus, the answer is behavior genetics.
