Answer: a) true
Explanation:
The goal of mitosis is to produce daughter cells that are genetically identical to the mother cell, without a single extra or missing chromosome. Meiosis, on the other hand, is only used for one purpose in the human body: the production of gametes or sex cells, i.e. sperm and eggs. The question is oriented to mitosis, <u>in which prior to this cell division, the cell duplicates its DNA</u> so that each daughter cell then inherits the genetic material. That is, the cell originally possesses 23 chromosomes, they duplicate to a total of 46 so that then each daughter cell receives 23.
The metaphase is the second phase of mitosis and meiosis that occurs after prophase where the envelope is lost and microtubules of the achromatic spindle (also called meiotic or mitotic) appear.
During metaphase, the chromosomes align themselves in the middle of the cell and this balanced midline spindle alignment is due to the equal and opposing forces generated by the kinetochore brothers.
Then during metaphase, the chromosomes will line up in the center of the cell to be separated and go each to a different daughter cell. But the moment they're found there, each orientation of chromosomes produces gametes with the same genetic information from each parent. <u>Because because there have been no changes or mutations in the chromosomes, they have duplicated and have the same genetic information.</u>
Acid-fast bacteria are gram-positive, but in addition to peptidoglycan, the outer membrane or envelope of the acid-fast cell wall of contains large amounts of glycolipids, especially mycolic acids that in the genus Mycobacterium, make up approximately 60% of the acid-fast cell wall

<span>Nociception is the physiological sense that signals the brain about damaged nerves or tissue. Felicia's nociceptors, or pain sensory receptors, respond to the damaging stimulus of the hammer on her thumb by sending information to the spinal cord and brain, making her feel physical pain, thus allowing her to react to the situation in an appropriate manner. Even though her pain receptors are usually silent (or dormant), they react instantaneously to the damage.</span>
Answer:
Thực vật, giống như tất cả các sinh vật sống, có những nhu cầu cơ bản: nguồn dinh dưỡng (thức ăn), nước, không gian để sống, không khí và nhiệt độ tối ưu để phát triển và sinh sản. Đối với hầu hết các loài thực vật, những nhu cầu này được tóm tắt là ánh sáng, không khí, nước và chất dinh dưỡng (được gọi là LAWN viết tắt).
