Answer:

photosynthesis

Explanation:

Photosynthesis is the process used by algae, green plants and some types of bacteria to convert solar energy into chemical energy. During photosynthesis, carbon dioxide (CO2) is consumed and oxygen (O2) is released. In the primitive Earth, the photosynthetic marine organisms helped to replace atmospheric CO2 with O2, which was one of the most important gas components in the atmosphere. Moreover, the ozone (O3) is generated when O2 reacts with sunlight. In the stratosphere, this gas (O3) formed a layer that is capable of filtering ultraviolet harmful radiation.

How has shopping changed in the last two decades answers?
wariber [46]
I believe a lot of things have changed in the last two decades. This has been mainly attributed to the growth in technology, with the introduction of ecommerce, shopping has become a much more personalized experience, customers will not have to walk on a physical store but instead they can make an order while sited in a couch and get delivered to them, the consumer expectations are very different compared to the past two decades; the new speedy and interconnected world that technology has delivered means that customers now have much higher expectations when it comes to the brands that they buy from.

What is the general name for a cell that is capable of receiving signals through its receptors?
qwelly [4]

Answer:

target cell

Explanation:

Cell communication includes one or more signaling cells and the target cell. Signaling cells produce signals. In the case of chemical signaling, the signaling cells produce chemical signals such as hormones or neurotransmitters or ligands. Target cells are the cells that respond to a specific signal produced by the signaling cell.

To receive and respond towards the signal, the target cells produce receptors where the signaling molecules bind to produce the desired effects in the target cells. For instance, liver and muscle cells are one of the primary target cells for the pancreatic hormone insulin.

The period of time between meiosis I and II is called __.
Ilia_Sergeevich [38]

Answer:

Interkinesis

Explanation:

Meiosis i is the first cell division, where the parent cell divides into two cells. Each of these cells undergoes a second division in meiosis ii, to form a total of four daughter cells.

Between meiosis i and ii there is a rest period. This is called interkinesis. No DNA replication occurs in this stage (unlike in interphase). What does happen is that the nuclear envelopes temporarily reform between telophase I of  meiosis I and prophase II of meiosis II Not all organisms have the interkinesis stage, some proceed directly to meiosis II after meiosis I
