Answer:
C
Explanation:
Newton's Second Law of Motion states that acceleration is dependent on 2 things: the net force acting upon the object and the object's mass.
This law is shown is these equations:
acceleration=net force/mass
net force=acceleration*mass
Hope this helps! :)
Answer & Explanation:
There are many differences between each type of microscope. One of the biggest is the magnification. Electronic have 10,000,000X and light have 1000X. Also, the type of lens is different, light use glass lenses while electronic use electromagnetic lenses. Finally, the source of view capacity is different, light use, as its name says, light, while electronic use charged particles like electrons.

Which of the following would result in fraternal twins, who don't have identical DNA? A. Two sperm fertilizing a single egg B. One sperm fertilizing a single egg C. Two sperm fertilizing two different eggs that were released in the same cycle D. One sperm fertilizing a single egg that splits into two embryos
<h2><u>Answer</u>: </h2>
Fraternal twins do develop when two sperms do fertilize two different ova that are released at the same time of a menstrual cycle.
Option C
<h3><u>Explanation:</u></h3>
Twins are of two types - Monozygotic twins or identical twins, and Dizygotic twins or fraternal twins.
Fraternal twins develop rarely, when during the menstrual cycle of the would be mother, two ova are released by two ovaries. So, two sperms fertilize the two ova separately. These zygotes develop into two separate embryo in their own separate amniotic sac. Being developed from separate sperm and separate ovum, the twins have not much similar characteristics unlike identical twins.
Only the fraternal twins can have different genders, like one can be male and other female. Monozygotic twins are always of same gender.
Yes, because even though other trees produce more oxygen, the small trees will still produce some oxygen. On top of this there are more small trees than big trees, so even though they make less oxygen, in whole they end up making more when added together!
