I believe the answer is PREZYGOTIC isolating mechanisms
Explanation:
we all want to improve air quality in our environments. especially in cities.., unfortunately, the $ you save from "going green," will now cause extra taxes,in the near future, which will defeat the purpose of saving $...from green sources adding another tax for your hard earned resources, example, when u buy a property with wooded areas, in rural towns of illinois, you are charged a green tax, plus higher property taxes to compensate electricity.
therefore, investment in clean energy shud b divided into yearly income per year..hense, people of higher income shud b taxed mor to the rich and people who can afford it. bluecollors are always taxed more than peps
that can actually afford it..
just my thought...
Answer:
The protein is a symport protein.
Explanation:
Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.
There are three types of transport proteins: uniport, symport and antiport transport proteins.
Uniporters are involved in moving only one molecule across a membrane
Symporters are involved in moving two or more molecule across a membrane in the same direction.
Antiporters are involved in moving two or more molecule across a membrane in opposite directions.
From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.
Answer:
Columnar epithelial tissue.
Explanation:
The above scenario confirms that these are simple columnar epithelial tissue because columnar cells are tall, narrow and nucleus in the tall column like cells located at the basal end of the cells. Columnar epithelial tissue are responsible for absorption and secretion of molecules. These are present at some part of digestive tract, female reproductive tract, and respiratory system.
