false I think, but I don't know for sure
Answer:
True
am not sure but my explanation:
An oxygen atom possesses 8 protons, 8 massive, positively charged nuclear particles. There are also 8 massive, neutrally charged nuclear particles, 8 neutrons in the common isotope, 16O. And orbiting the nuclear core, there are 8 electrons, fundamental particles with negligible mass that each possess a formal negative charge.
Any atom with 8 protons is automatically an oxygen atom by defintion. 7 protons specifies a nitrogen atom; 9 protons specifies a fluorine atom. Of course, oxygen generally takes the form of the dioxygen molecule, O2. The number of protons gives Z, the atomic number, which is different for each element.

Explanation:
Why might the expression of a transgene be especially abnormal in vertebrates with larger average size of genes and amount of heterochromatin in their genomes?
Answer:
position effect
Explanation:
Position effect refers to the consequences on the expression of a gene/transgene when it is inserted into a new genomic location, thereby explaining how transgene's behavior is affected by its genomic location. The differences in expression of the inserted gene/transgene are generally due to its proximity to regulatory sequences (e.g., enhancers). Species with larger genomes have many genes as well as long intergenic regions where heterochromatin may spread stochastically (randomly) in order to switch on/off the gene expression, thereby resulting in unstable phenotypes.
Immunological memory accounts for: Group of answer choices the observation that some strains of the pathogen that causes dengue fever cause more severe disease than others the ancient observation that someone who had recovered from the plague could safely care for those newly diseased the human body's ability to distinguish self from non-self the ability of a helper T cell to signal B cells via cytokines
Answer:
The correct answer is - the ancient observation that someone who had recovered from the plague could safely care for those newly diseased.
Explanation:
Immunological memory is the ability of the body to recognize or identify and kill or remove the antigen, very quickly and faster, the body has previously encountered and developed an immunological response.
These memories are developed due to memory B cells or, memory CD8+ T cells and memory CD4+ cells developed by the first-time immune response. If someone who had recovered from the plague must have developed memory cells for the antigen and safer than those newly diseased.
The vesicles involved in endo/exocytosis are surrounded by a phospholipid membrane.
A. True
B. False
Answer:
A. True
Explanation:
The vesicle travels to the cell membrane. The vesicle fuses to the plasma membrane, during which the two bilayers merge. The vesicle's contents are released into the extracellular space. The vesicle either fuses with or separates from the cell membrane.

Suggest two reasons why more of our fish are supplied by fish farming rather than from traditional
fishing
Answer:
Due suitable environment and high productivity.
Explanation:
More fish are supplied by fish farming rather than from traditional because farms are build in order to harvest more fish by providing suitable environment to the fish. In transitional ways, fish are caught in nets from the rivers by local people for theirselves and the extra will sold in the market. In rivers there are less number of fish which does not meet the requirements of people so that's why commercial farming of fish can be done.

One of your team members suggested harvesting crops to supply food resources for the future Martians. Would this be a feasible suggestion? What factors need to be considered in order to have a thriving agricultural life on the red planet?
Answer:
Yes.
Explanation:
Yes, it s a feasible suggestion by harvesting crops to supply food resources for the future Martians if the environmental conditions are suitable. Suitable temperature, humidity, water requirement and optimum amount of light are the factors need to be considered in order to have prosperous agriculture on the red planet. If these factors are available in optimum range so we are able to grow crops for the Martians to survive.

economy of the country. Food and agriculture industries depend a
lot on both these organisms. Discuss how these organisms can
help to improve the economy of the country now.
