The statement 'polypeptides in the ER are usually larger than polypeptides synthesized from the same mRNA that have not entered the ER' is false.
The rough endoplasmic reticulum is the site where polypeptides enter so that protein formation can take place. Apart from protein formation, polypeptides are needed for various other metabolic functions by the ER.
Those polypeptides that are smaller in size can enter the endoplasmic reticulum because of the entering space and the small size of the endoplasmic reticulum. On the other hand, the polypeptides that are large, although being synthesized from the same mRNA, stay outside as they cannot enter the ER due to their large size.

<span>The correct answer is genetic material of sperm and egg combined.
</span> <span>Fertilization is the fusion or joining of the egg and the sperm (haploid gametes), resulting in a fertilized egg, otherwise known as a zygote (diploid). The process of fertilization is very complicated and comprised of many steps, but the key step involves components of and signalling between, both sperm (spermatozoa) and egg (oocyte).</span>
Answer:
a:Triploblastic, pseudocoelomate, protostome
Explanation:
When it comes to embryonic tissue layer in animals, some have two while some have three. Those with two layers are diploblastic while those with three layers are said to be triploblastic.
Body cavity evolution also vary in animals according to their development levels. Some animals lack body cavity totally and are referred to as acoelomates, some have a mesoderm-like fluid filled cavity and are referred to as pseudocoelomates while others have true body cavity with peritoneum and are referred to as coelomates.
During embryonic development, the mouth is formed first in some animals and they are referred to as protostomes while those in which the anus are formed first are referred to as deuterostomes.
<em>Hence, the best terms that describe the animal in question are triploblastic, pseudocoelomate, protostome.</em>
The correct option is A.
Answer:
It is an African artiodactyl mammal
Explanation:
Answer:
Gregor Mendel's studies of heredity established the field of modern genetics. ... As you will learn, Mendel uncovered some of the rules of inheritance that scientists continue to ... Mendel created an F1 generation and observed its traits. ... Answer The allele for red eyes (R) is dominant, so all of the offspring will have red eyes.
