Answer:
A river system is made up of a river and its tributaries.
What is a river system?
A river system is a term used to describe the broader networks of streams, lakes, and rivers that are tributaries and distributaries of a larger river. For instance, the Mississippi River system includes the Ohio, Red, and Missouri rivers, all of which drain into the Mississippi River. Due to its interconnectedness, the condition of one river may have an effect on the health of the other rivers in the same river system. A river system can also include other types of terrain, such as the wetlands and flood plains that are affected by a major river and its tributaries and distributaries. The majority of the time, rivers have a primary source, such as snowmelt from a mountain that cascades into a number of streams, which eventually merge to form a river that empties into a much bigger river. This is an illustration of a river network. River systems are ecosystems from an environmental perspective, and if even one component of the system is contaminated or destroyed, it may have a severe impact on things like water quality and the health of plants and animals. For instance, the effects of high pollution levels or prolonged drought near a river's source will be felt throughout the rivers and lands that make up the river system.
An example of this is the Amazon River in Brazil (South America).

For this question, you have to draw a punnet square
Explanation:
A B
i Ai Bi
i Ai Bi
For AB blood type, one parent can give either an A or a B. For the other parent because they are 0 blood type that means that they are negative for both factors.
For someone who would be A, they could be AA or Ai( but that is irrelevant for this question)

is water losing through transpiration harmful or benefical for plant
Answer:
Beneficial. Read below
Explanation:
Water naturally does evaporate from the leaves. When it does, it makes a sort of suction in the 'pipes' of the plant. Think of it like when you drink from a cup with a straw. You take juice out from the straw by sucking it but that makes the juice still in the cup go up to replace that lost juice. This is how plants absorb water from the roots. If transpiration didn't happen, plants wouldn't be able to absorb water apart from osmosis but that would be too slow.

Describe the features of the respiratory epithelium and explain in terms of physiology how they protect the lung.
The essential roles including barrier protection, fluid balance, the release of particulate, initiation of immune responses, mucus and surfactant exhibit, and repair following injury.
What is respiration?Inhalation:
On inhalation, the pressure in the alveoli is high, hence the Oxygen diffuses to the nearby blood through the membrane.
Exhalation:
It is the process in which a person releases the air collected in the lung. During exhalation, the pressure in the alveoli is low, hence the carbon dioxide present in the blood is diffused out into the alveoli.
Therefore, the expandable structure of alveoli helps the respiratory system to follow its function.

ubiquitin attaches to proteins via many biochemical reactions, please explain how this attachment targets protein for degradation and describe the biochemical reactions.
The ubiquitin attaches to proteins via many biochemical reactions, and targets the protein for degradation.
Which residue of goal protein attaches with ubiquitin?Ubiquitylation includes ubiquitin conjugation to a lysine residue of a goal protein or to an already-sure ubiquitin molecule, thereby forming a branching structure. This amendment can serve to goal the protein for degradation with the aid of using the 26S proteasome if the more than one ubiquitin molecules are conjugated with the aid of using lysine-48.
Proteins are marked for degradation with the aid of using the attachment of ubiquitin to the amino organization of the facet chain of a lysine residue. Additional ubiquitins are then delivered to shape a multiubiquitin chain. Such polyubiquitinated proteins are identified and degraded with the aid of using a large, multisubunit protease complex, known as the proteasome.

Look at least two molecules diagrams and think about the features of compounds.
Answer:
---> are isomers of each other
---> have same molecular formula
---> are both hydrocarbons
---> have same number of each kind of atom
Explanation:
Isomers with the same molecular formula. The molecular formula gives a list of the type and quantity of each element in a molecule.
In other words, they are two different molecules with the same type and amount of atoms. The difference is that their structures are different. That being said, the structural formula of the molecules would not be the same. Hydrocarbons are molecules that only consist of carbon (C) and hydrogen (H) atoms.
