Answer:
So, it produces gametes I wouldn't say gametes cause meiosis so false, hope this helps.
Explanation:
It produces gametes with unique chromosomal combinations. Two gametes combine to form an offspring in se-xual reproduction. Meiosis I occurs within female cells and leads to the formation of egg cells (oocytes). Meiosis II occurs within male cells and leads to the formation of sp-erm cells.
True. A human haploid cell contains contain only one complete set of chromosomes (23). Meanwhile, a diploid cell has 2 set of chromosomes from the parents, thus containing 46 chromosomes.
The central nervous system includes the brain and spinal cord.
Answer:
Filip's medical report, diagnosed with Alzhaimer's, may reveal a diminished production of acethylcholine.
Explanation:
Alzhaimer's disease is a neurodegenerative condition that causes immediate memory loss, behavioral changes and cognitive impairment, due to neuronal alterations and atrophy.
The neurotransmitter acetylcholine —related to neuronal transmission and body movement— may experience a decrease in its production leading to Alzheimer's, according to the cholinergic hypothesis.
Many therapies and treatments at present are based on the use of drugs to correct the acetylcholine deficit.
Regarding other options:
- <em>Dopamine: alteration or deficit is related to Parkinson's disease.</em>
- <em>Gamma aminobutyric acid (GABA): deficiency is not common and is related to a type of congenital and infantile neuropathy.
</em>
- <em>Serotonin: deficit of this neurotransmitter can lead to depression and psychological disorders.</em>
Answer: 37 chromosomes.
Explanation: As is typical of mammals, llamas are diploid organisms, meaning that the number of chromosomes in each of their somatic cells is exactly twice of that found in the gametes (the so-called haploid number, referred to as "n"). If a particular species has 74 chromosomes in its somatic cells, we should expect to find 74/2=37 chromosomes in each gamete.
