Electron microscope‘s differ from light microscope’s in that they produce an image of specimen by using a beam of electrons rather than a beam of light. Electrons have such a shorter wavelength than visible light, and this allows electron microscope to produce higher resolution images than standard light microscope‘s
1.The trait is recessive. This means both your parents were carries, but did not show the trait. For example, B represents the allele, you're parents would have to both be Bb. This means that they are carriers, and you could have inherited either BB/Bb/bb - you actually inherited bb, which means because its a recessive trait you will show the trait.
2. For your children, it depends on who you have them with. Because you're bb, you will definitely pass on the b allele, so any child you have would be a carrier and could potentially have the trait. If you have a child with someone BB, all your offspring will be Bb (carriers- as the kid gets one allele form each parent). If you have a child with someone who is bb, all your kids would definitely have the trait. However, if you have a child with someone who as Bb, then the four outcomes are Bb Bb bb bb, so there would be a 50% chance of your kid having the trait.
Hope this helps!! :)

Answer:
The correct answer is - neurulation
Explanation:
The neural groove is a groove of the neural plate which is a thick plate that is enclosed by the neural folds of an embryo. The neural grove forms the neural tube which expands and develops into the spinal cord and brain.
The development of the neural grove is taken place during the process known as neurulation which is characterized by all characteristic development related to the neural groove and ventricular system.
Answer:
D. Discovered chemolithotrophs in natural enviroments.
Explanation:
Sergei Winogradsky was a russian microbiologist. He observed in his research with genus of bacteria <em>Beggiatoa, </em>they were able to oxidize hydrogen sulfide as an energy source. Being the first example known of lithotrophs (organisms that use inorganic substrate in order to obtain energy).
