The answer is 23.
A human being receives 23 chromosomes from each parent. So each human has 46 chromosomes. Chromosomes X and Y determines your sex.
During mitosis, chromosomes are moved and separated through the use of spindles composed of microtubule structures.
Explanation:
Throughout mitosis, the chromosomes are initial replicated (copied) and so distributed into a pair of new "daughter" cells. They're replicated throughout the S section of interphase, and within the following phases (prophase, metaphase, anaphase, telophase) are organized, separated, and repackaged at opposite ends of the cell, at that purpose the cell divides. The strand of chromosomes split just like the cell throughout the cellular division. They split in half.
Answer:
A. They do not use up any energy finding mates.
Explanation:
The asexual reproduction consists of one parent which are same to each other while on the other hand consists of two parent that produced unique.
For species survival, the reproduction of protozoa asexually rather than sexually could be better when they don't use much time and energy for determining the mates
Therefore in the given case the correct option is A.
Answer:
Yes, the similarity of embryos across species provide evidence for evolution. The similarity of the embryos indicates that they evolved from the same common ancestor, the embryos at letter A clearly indicates this.
