If CPR is not performed, C. 4 minutes will elapse before the brain becomes damaged from lack of oxygen.
One minute isn't enough time - you can even hold your breath for one minute without fainting. Some people can even do it for 2 minutes.
Ten minutes is too long - you would be long dead.
Edouard van beneden proposed that an egg and a sperm, each containing half the complement of chromosomes found in somatic cells, fuse to produce a single cell called a zygote.
Zygote
A zygote (from the Ancient Greek zygtós, "joined, yoked," from v (zygoun), "to join, to yoke") is a fertilized egg. [1] is an example of a eukaryotic cell produced by the fertilization of two gametes. The genome of the zygote, which is made up of the DNA from each gamete, has all of the genetic material for a brand-new unique organism.
The zygote represents the earliest developmental stage of multicellular organisms. A zygote is produced when an egg cell and sperm cell combine to form a new, distinct organism, as is the case in humans and the majority of other anisogamous organisms. The zygote can split asexually through mitosis in single-celled organisms to create identical progeny.

Answer:
a and d
Explanation:
<em>Among the products of meiosis listed, aB and Ab would be the recombinant types because recombinant gametes are gametes that are unique from the haploid gametes that made up the diploid cell. </em>
A and B alleles are on a particular chromosome while a and b alleles are on another chromosome. During the process of gamete formation/meiosis, the possible gametes are;
<em>While the first two gametes are parental (because they made up the original diploid cell), the last two gametes are recombinant gametes.</em>
Hence, from the list of options, aB and Ab are the only recombinant types.
<em>The correct options are </em><em>a</em><em> and </em><em>d</em><em>.</em>
<em />
yes, because its close to a and b.
