Answer:
option d
Explanation:
Meiosis stage was formerly called the reduction stage involving two divisions; meiosis I and II. After the first stage of meiosis, the ploidy level of each of the daughter cell changes is in an haploid state, meaning here the DNA content has been reduced by half. In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). This haploid state is still maintained by the meiosis II just undergoing the normal mitosis division.
Answer:
The fossil record supports a "biological" type of evidence.
Explanation:
<u>Fossils-</u> this refers to the <em>remains of prehistoric organism.</em><em> </em>It provides a trace of a <em><u>once-living plant, animal or organism. </u></em>
When it comes to evolution, fossils provide a biological type of evidence. This means that,<u><em> it shows how organism have greatly changed from the past.</em></u> When you study fossil records, you can compare it with the animal, plant or human structure nowadays. You can compare them side-by-side. So, you'd get that idea on how prehistoric things lived in the past and how they evolved up to the present day or became extinct.
<em>Most of the fossils can be found on sedimentary rocks.</em> You can also tell their ages according to which layer they belong. It is said that older layers consist of older fossils and they appear at the bottom while younger layers consist of younger fossils and they appear on top.
