Answer:
The energy from the cell will block substances from being in the animal and stop the toxins from getting into the animal cell.
Explanation:
The job of this energy is to block everything from coming in and out of this cell membrane.
Fluids, water, You loose salt water and electrolights when you perspire, when you drink water it doesn't have salt or electrolights it just has water so it can only replace your water
Answer: Basically, DNA holds to code for making RNA. The process of making RNA from DNA is called transcription.
After the RNA that is made, it goes to a ribsome. Ribsomes use the RNA sequence to make an animo acid sequence, which are proteins. The processes of using RNA to make proteins is called translation.
These proteins are what make you up! They are responsible for your different phenotypes.

Answer:
Viruses can be used to insert genetic material into cells during gene therapy
Explanation:
Gene therapy is a process used to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a vector is genetically engineered to deliver the gene. Certain viruses are often used as vectors because they can deliver the new gene by infecting the cell. The viruses are modified so they can't cause disease when used in people.
Answer:
In bryophytes, the sporophyte is minute and dependent on the relatively prominent and nutritionally independent gametophyte for resources. The moss gametophyte looks like a miniature herb, with tiny leaf-like photosynthetic organs. The gametophyte generation begins as a dormant spore, which germinates under appropriate conditions to produce filamentous and branching protonemal tissues. These form multicellular bud-like structures, each of which develops into a leafy shoot. The mature gametophytes produce male and female sexual organs, the antheridia and archegonia, respectively. The gametophyte is often sexually distinct, and plants are either male or female.
Each antheridium has an outer layer that encloses and protects thousands of motile sperm, which swim through available external water layer to the egg. Fertilization at the base of the cylindrical archegonium produces a diploid zygote which develops into an unbranched sporophyte. The sporophyte consists of a thin stalk attached to the gametophyte, and a capsule that encloses the sporophytic meiotic cells.
In recent years, the mosses Physcomitrella patens and Funaria hygrometrica have emerged as attractive model systems for studying gene function in non-vascular plants because of the relative ease of molecular manipulation by homologous recombination. Mutants affecting gametophyte development have been isolated and their analysis should provide insights into the molecular basis of gametophyte development in mosses.
