Answer:
D
Explanation:
So basically genes are made of DNA molecules. DNA molecules are the building blocks of genes.... if you think about legos for a second the building blocks of legos would be plastic right? because without plastic you don't have legos which is same here... genes are legos and DNA molecules are the plastic that make them (if you get my analogy).
So genes are the information carriers because they carry information on how to make a certain protein or express certain characteristics. Gene directs the cell to make certain proteins and proteins are the key players that are involved in many cellular process because they carry out major functions hence, the protein determine the function of cell because without protein the cell would have no function
Answer:
C:ocean plates collide w/ the continetal plates
Answer:
A postsynaptic potential is defined as excitatory if it makes it easier for the neuron to fire an action potential. ... A postsynaptic potential is considered inhibitory when the resulting change in membrane voltage makes it more difficult for the cell to fire an action potential, lowering the firing rate of the neuron.
Answer:
Answer is 2. Fibroblasts fail to divide.
Explanation:
Tissue culture experiment is the experiment where tissues are grown in an artificial medium. This involves the use of growth medium such as agar or broth. This process help to produce needed tissues in a short period of time.
Fibroblasts are cells which are found in the collective tissues, and they produce collagen. The collagen produced by the Fibroblasts play important role in tissue repair. Fibroblasts are regarded as the main cells in the connective tissue.
Note that, PDGF, which is Platelet -derived growth factor in full, is a growth factor regulating cell growth and it's division.
Protists are a group of organisms that are characterized as Eukaryotes that are neither plants nor animals nor fungi. They are very diverse, and there are many hypotheses about their classification. The cladogram for protists is constantly changing and, sometimes, there are opposite hypotheses that both have data to support them. What is the implication of a changing hypothesis.
It is acceptable because data are still being collected.
It is acceptable everything in science should always change.
It is not acceptable because the correct answer needs to be found.
