Select two items that biologists agree are necessary in order to consider an organism “alive.” For each, give an example of a nonliving object that otherwise fits the definition of “alive.”
Answer:
Cellular organization and metabolism are two items necessary to consider an organism alive.
Explanation:
There are certain characteristics that belong to living beings and that they all have in common. These are distinctive characteristics that do not include any non-living object. Among others, we can name the followings:
1) Precise cellular organization. The cellular theory states that every living being is conformed of basic units named cells and their products that result from the cellular activity. Although organisms vary in size and shape, all of them are formed by cells. A cell is the simplest part of the living matter which is capable of performing every necessary activity needed for life. Some of the simplest organisms, such as bacterias or some algae, are unicellular. This unique cell must be polyfunctional, as it has to perform many activities. On the other hand, many other organisms are highly complex pluricellular. All the processes of the entire organism depend on the correct and coordinated functioning of every constituting cell. The more complex the organism is, the more specialized are the cells, differentiating from each other, and acquiring certain specific functions. These are, for example, the epidermic cells, muscular cells, nervous cells, reproductive cells, among others.
2) Metabolism. In any living being there happen many essential chemical reactions needed for appropriate nutrition, growth, cellular repairing, energy conversion, among others. All of these chemical reactions in the organisms are known as metabolism. These cellular activities begin when the organism takes life, and continue through its whole life. When chemical reactions stop, the organisms might be considered to be dead. Every specific cell in the organisms take substances that chemically modify, in many different ways, to integrate new cellular components. Some of these nutrients are used in cellular respiration. During this process, part of the energy stored is taken by the cell for its own use. This energy is also needed for synthesis and other cellular activities. In most organisms, cellular respiration requires oxygen provided by the gas interchange. Cellular wastes, such as carbon dioxide and water must be eliminated from the organism. Every chemical reaction is regulated by specific enzymes.
Kinases and phosphatases are essential in the cell because they directly Kinases and phosphatases are essential in the cell because they directly turn proteins "on and off" through changes in phosphorylation status. destroy IP3, turning off that signaling pathway. bind hydrophobic hormones in the cytoplasm. bind and release calcium ions. activate and repress genes.
Answer:
The correct answers is "turn proteins "on and off" through changes in phosphorylation status".
Explanation:
Kinases and phosphatases are two type of enzymes that catalyze the transference of phosphate groups, where kinases add phosphate groups and phosphatases cleave them. Both are essential because turn proteins "on and off" through changes in the aforementioned phosphorylation status. Most of the phosphorylation are reversible, and they are considered as allosteric regulation
Kinase is an enzyme responsible for attaching phosphate groups to protein while phosphatases remove the attached phosphate group from the protein.
These two enzymes modulate the activity of a protein in a cell which is very important for cell functioning and communications.
The correct answer is:
Kinases and phosphatases are essential in the cell because they directly turn proteins "on and off" through changes in phosphorylation status.
The reason for the answer is:
Phosphorylase and kinase are the enzymes that catalyze the transfer of phosphate groups to the proteins.Kinases are responsible for adding phosphate groups while phosphatase cleaves them. They are antagonistic.They take part in the phosphorylation process of protein and are reversible.They regulate the working of protein by switching on and off with the help of these enzymes.Therefore, Kinases and phosphatases are essential in the cell because they directly turn proteins "on and off" through changes in phosphorylation status.

Why does the reduction of the dye DCPIP work best using the chloroplasts whose outer envelopes have been damaged during preparation?
Answer:
NADP is the cofactors in photosynthesis which loses electrons,becomes reduced(NADPH) in photosynthesis. It transfer electrons in reduced form(NADPH) into the stroma of the chloroplast. The H is splits into e- and H+
These electrons for the ETC chains, generates the PMF for pumping H+ as protrons into the thylakoid intramembranes.
Outer membrane covers the intramembrane space, between these two membranes layers. The protons in the intramembrane space generate the electrochemical gradient for the supply of the energy used by ATPase synthase for ATP synthesis from phosphorylation with ADP.
The chloroplast is made up of both the outer and inner membrane,separated by the intramembrane space. The walls of the intramembrane space is guided by the outer envelope.
Therefore with the outer envelope removed, the intramembrane is exposed,more protons(H+) are released, but can not be held in the outer envelope to form electrochemical gradients,beacause the intramembrane space is now permable.
Thus the rate of reduction of DCPIP is faster.The color changes to colorless increases when reduced , from blue color.
Explanation:
The reduction of the dye DCPIP (2,6-dichlorophenolindophenol) works best using chloroplasts whose outer envelopes have been damaged during preparation because it allows easier access for DCPIP to the electron transport chain (ETC) components.
The outer envelope of chloroplasts contains phospholipid bilayers that act as barriers, limiting the movement of molecules in and out of the chloroplasts.
When the outer envelopes are damaged, DCPIP can diffuse more freely into the chloroplasts and come into contact with the ETC components, particularly photosystem I.
DCPIP acts as an electron acceptor, and in the presence of light, it is reduced by electrons from photosystem I, resulting in its color change from blue to colorless.
The damaged outer envelopes facilitate the interaction between DCPIP and the ETC, leading to more efficient reduction.

Answer:
Increased evaporation and transpiration dries out the ground leaving less water to move to the atmosphere fewer clouds and less precipitation, which can lead to drought conditions.
In some areas evaporation and transpiration from plants can be so high that the amount of water available to move to the atmosphere is significantly reduced. This is usually the case in areas that are lacking in open water resources.
As there is less water moving to the atmosphere, there will be less water condensing into clouds and thus less rain. If this persists, it can lead to a drought.
