The answer is: d. comparable in size to the heterosexual females
Simon LeVay is a neuroscientist that studies the relation of brain structure and sexual orientation. He examines the interstitial nucleus of anterior hypothalamic cells. The size of the nucleus in homosexual is found to be similar to women while the heterosexual male is much larger. The result doesn't enough to say that sexual orientation is genetic. This proves that there is the dimorphic nucleus in different sexual orientation.
Answer:
4) 4
Explanation: Sexual reproduction is a type of reproduction in which offspring is produced by the mating of male organism with female organism. In sexual reproduction, half genes come from male and other half comes from female organism producing a diploid zygote having double number of chromosomes. So in fruit fly, parents have eight chromosomes so 4 chromosomes comes from each organism.
<span>Nutrients and oxygen
Cellular respiration involves a series of chemical reactions. The enzymes increase the rate of the reactions.The reactions that are catalysed by enzymes actually helps the organism to grow, respond to various changes in the environment, reproduce and continue maintaining their own structures. Cellular respiration is also considered a part of the metabolism process. This process actually helps in carrying the oxygen through the blood.<span> </span></span>
Answer: Antibiotic resistance is a real but gradual process
Explanation: Usually, antibiotics primarily address various targets: pathogen, sites of pathogenic attack, or nearby white blood cells etc. These remedial action occurs at the molecular and cellular level. Invivo, antibiotics are metabolized (chemically broken down) to yield a smaller and active form that attaches to the pathogen's cell wall and breaks it down to gain entry into its nuclear material (DNA) inhibiting an important nitrogenous base from pairing accurately, when this happens, DNA replication in the pathogen is disrupted.
Then, pathogen tends to undergo point mutations (change of a base to another) in order to evade tailored-made antibiotics, but could be vulnerable to broad spectrum antibiotics.
So, nature permits only the pathogens that could reverse its genome and morphology by point mutations and structural changes respectively - resulting in antibiotic resistance as you already mentioned
I hope this helps
