Answer:
True
Explanation:
The embryonic development of fertilized egg includes cleavage, blastulation, implantation, gastrulation and organogenesis.
Cleavage division divides the zygote into blastomeres. First cleavage division result in two blastomeres, second cleavage division results in a transient three cell stage. Third cleavage division forms 8 blastomere. These result in the formation of a sold ball of cells called morula. Morula is 16 cell stage and it descends towards the uterus in 4-6 days. As the morula enters the uterus, it gets a rich supply of nutrients. Trophoblast cells are formed which secrete a fluid into the interior creating a cavity called blastocoel. The inner cell mass now comes to lie on one side as embryonal knob. With the formation of blastocoel, morula is converted into blastula which is called blastocyst in mammals.

<span>The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body. Blood that travels from the lungs to the body contains oxygen from the lungs. Blood that travels from the body to the right side of the heart contains CO2 which is breathed out when it gets to the lungs.</span>
The correct answer is 2.
Type 2 diabetes is a lifelong condition which involves high levels of glucose in the blood and is caused by irregularities in insulin. There are specific factors which can increase the risk of developing type 2 diabetes and these are excessive weight and fat tissue, old age, family history of type 2 diabetes, race, reduced physical activity, high blood pressure and others.
Mr. Joiner's age and race could be considered risk factors since the older you are the more increased is the risk. Also, African American people are found to be at higher risk for type 2 diabetes. However, these are risk factors which he cannot control.
The risk factors that Mr.Joiner can control are his reduced physical activity due to his sedentary life and his weight (since his BMI indicates that he is overweight). Most probably he should also try to have more healthy eating habits, by cooking healthy meals at home instead of dining out so often.
