Answer:
I think the answer is B. I think energy decreases as it moves up tropic levels when it is lost as the organisms from one level consume the organisms in the other. 
Explanation:
It can't be A because animals do travel from one ecosystem to another. It's migration. It's not C because air can be used by organisms as once as the air moves out of their ecosystem because air is everywhere and the organisms need air to breathe and to live. D is definitely incorrect because matter can't be created or destroyed. Remember that an ecosystem is the organisms physical environment. I hope this answers your question.

If a phospholipid is located in the outer layer of the bilayer in a vesicle, it will end up in the cytosolic face of the bilayer when the vesicle fuses with the plasma membrane.
The lipids on the exterior of a vesicle will end up in the phospholipid layer on the interior (cytosolic face) of the plasma membrane when it fuses with the membrane. The extracellular fluid in the plasma membrane will be in contact with the lipids on the interior of the vesicle membrane.
What is a phospholipid?
Phospholipids are a subclass of lipids that have two hydrophobic "tails" made of fatty acids connected by an alcohol residue. Their hydrophilic "head" contains a phosphate group (usually a glycerol molecule).

Answer:
Please find the complete table attached as an image
Explanation:
This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code). 
- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc. 
- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid. 
The table has been completed and attached below. Note that in the amino acids row;
GLY means Glycine
ILE means Isoleucine
VAL means Valine
GLN means Glutamine
CYS means Cysteine
THR means Threonine
SER means Serine
PHE means Phenylalanine
ALA means Alanine
LEU means Leucine
