Well i don’t know what you could pick bc the statements aren’t here i don’t think you added them but here is the detention of meiosis // a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
hope that helps
<span>The head of the sperm contains the necessary enzymes to help it penetrate the oocyte. The sperm cell is anatomically structured to have four parts which are the head, neck, midpiece, and a tail. Inside the head of the sperm are densely coiled chromatin fibers that contain the nucleus for helping the sperm penetrate the female fertilized egg necessary for reproduction.</span>
Atomic number of an atom equals to the number of nucleus in the nucleus of the atom. Therefore, the answer is 74.
The proton of an element is never changed. No matter if it's an atom or ion. It's like an ID number for an element. It defines the type of element. Don't mix up atomic number with mass number though, mass number is the total sum of of the number of protons and neutrons in an atom.
Theres one more subatomic particle in an atom, that is electrons. But since they're too light, they won't be counted in mass. Also, the number of electrons in an atom equals to the number of proton, also the atomic number. If the number of electrons is different, it's no longer an atom, but an ion.
Answer:
b. Hiccupping is a vestigial reflex that suggests a common ancestry between humans and amphibians.
Explanation:
Hiccupping refers to an involuntary contraction of the diaphragm that usually occurs several times per minute. Some research has suggested that hiccuping is an evolutionary remnant of amphibian respiration. This is because the mechanism is remarkably similar to the way tadpoles gulp air and water across their gills. This would mean that hiccups exist due to an antecedent to modern lung respiration.
idk about 10, i can't see the diagram
11. The moment magnitude scale is one of many seismic magnitude scales used to measure the size of earthquakes." The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale.
use that ^
