Answer:
a. two plant species flowering at different times.
Explanation:
<em>The only option that is not a post-zygotic reproductive isolation mechanism would be option a, when two plant species flower at different times.</em>
Post-zygotic reproductive isolation mechanisms are those mechanisms that act to ensure that the product of fertilization remains invalid. This is as opposed to pre-zygotic isolation mechanisms that act to prevent fertilization and hence, formation of zygotes.
In option b, c, d and e; the zygote has been formed already and all the forces are just acting to ensure that it remains invalid. whereas in option a, there is no fertilization yet.
<u>Two plant species flowering at different times will ensure that there is no cross pollination between the two species. Without pollination, there cannot be a zygote formation.</u>
Hence, the correct option is a.
Urbach-Wiethe disease is a rare genetic disorder that can cause calcification of brain tissue in the temporal lobes; this calcification can cause damage to the amygdalae.
<h3>What are the symptoms of Urbach-Wiethe disease?</h3>
The symptoms of the disease vary greatly from individual to individual.
They may include a hoarse voice, lesions and scarring on the skin, easily damaged skin with poor wound healing, dry, wrinkly skin, and beading of the papules around the eyelids.
<h3>What part of the brain does Urbach-Wiethe disease affect?</h3>
(1994, 1995) investigated a patient suffering from Urbach–Wiethe (UW) syndrome, a very rare autosomal recessive disease, which produces bilateral calcifications in the anterior medial temporal lobes, especially of the amygdalae, in 50–75% of cases (Newton et al., 1971; Staut and Naidich, 1998).

You could also say that the neutron is the odd man out because the number of protons and electrons are the same because the negative charge from the electronics attracted to the positive charge from the proton.
On the next line you could say the election is the odd man out because the protons and neutrons reside in the nucleus and the electrons fly at high speeds in the electron cloud.
Answer:
The lungs
Explanation:
The lungs in your body get filled up with air when you inhale. There are blood vessels around the alveoli in your lungs (which are tiny air sacs that hold the air). The blood vessels absorb the oxygen in a process called diffusion where gas diffuses through the one cell thick wall of the alveoli into the blood vessels. The circulatory system then pumps the blood around your body to the cells that need the oxygen.
