Answer: Sediment. Hope this helps :^)
Answer:
Plants and animals benefit each other as members of food chains and ecosystems. For instance, flowering plants rely on bees and hummingbirds to pollinate them, while animals eat plants and sometimes make homes in them. When animals die and decompose, they enrich the soil with nitrates that stimulate plant growth. I know it's not 5, but I hope it helped.
Think of it this way:
DNA inside cells store all the genetic information on a person's looks, eye colour, hair colour etc. It makes them unique. The analogy of being like books in a library basically suggests that in a library there is so much information and every book is different with different knowledge... That's basically what DNA is; millions of different information things.
Answer: close ended
Explanation:
In a job oriented interview both open and closed ended questions are asked to the job seeker. The open ended interview questions are generally very long answer type questions these questions allows the person to express. These questions are asked to learn about the personality and interests of the job seeker. The closed ended questions are the short questions and they are easy to answer and these can be answered in yes and no. These questions are asked and answered quickly. The chances of mistakes in these questions are more. The chances of misinterpretation of the question is always more in these questions. But these questions allow to get more information about the candidate as compared to the open ended questions as during the open ended question session the job seeker can manipulate the facts but in the case of close ended questions the asking tendency is rapid so no manipulation can occur.
Answer:
Here are the answers:
a. 4 Cell determination as an issue in the *rest is missing*
b. 4 They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.
c. 4 I and III only
Explanation:
The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.
Cleavage Planes:
Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.
Cell Differentiation:
Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
