Answer:
Valence
Explanation:
In an atom, the electrons at the outermost energy level is called as valence electrons. It is the valence electrons which participates and interacts with the other atoms and form bonds. The valence electrons of an atoms are important as they depict the chemical properties of an element.
Thus the valence electrons resides the outermost shell and surrounds the atomic nucleus.

Answer:
Water Withdrawal: it has happened in some lakes in Minnesota
Explanation:
The water cycle is influenced by seasonal-climatic fluctuations and human activity. Water withdrawal is one of the human activities that most seriously affect the amount of water in lakes and aquifers by reducing water storage, thereby altering the flow in streams, lakes and wetlands. Concerning this situation, the state of Minnesota incorporated 1- the use of a US database (State Water Use Database, SWUD) with useful water use information on withdrawals and consumptive uses and 2- an index based on the sum of permitted water withdrawal from surface and groundwater. This index estimates the use of water as a percent of the surface water runoff to define and predict the vulnerability of lakes, using data from 54 stream gages recorded from 1988-2007. The catchment scores are scaled from 0 to 100 depending on the percent of runoff used.

Answer and Explanation:
The cell looks like a prokaryotic cell. A prokaryotic cell might be recognized by the presence of flagellates used to move (the four long filaments located posterior to the cell). There are also many pili surrounding the cell wall (the small little filaments). There are almost no organelles. There is a circular DNI molecule concentrated in a nucleoid (which seems to be the grey oval in the middle of the cell). Prokaryotic cells also have different compartments that depend on the type of cells, such as chlorosome, carboxysome, phycobilisome, and others (which might be the dark spiral circle in the anterior part of the cell). Two differences with the cell of an onion peel are that the onion peel cell has its genetic material surrounded and protected by the nucleus membrane, whereas the prokaryotic cell lacks a delimitated nucleus. Also, the onion peel cell has a hexagonal shape and lacks flagellates and pili, unlike the prokaryotic cell, which uses the to move. The onion peel is a multicellular structure, while the prokaryote is a one-celled organism. There should always be a cover glass over the cell or tissue we are looking at.

Explain how the conversation of wetlands to farmlands has impacted stream and rivers
Answers
Answer:
Wetland reduction has caused a decrease in the absorption zones for excess water. If the excess water cannot be absorbed by the soil, it increases the incidence and magnitude of flooding.
The conversation of wetlands to farmlands has impacted stream and rivers as the Wetland reduction has been caused the decrease in the absorption zones for excess water. If the excess water cannot be absorbed by the soil, it increases the incidence and magnitude of flooding and this can be achieved by sustainability.
What is the process of achieving Sustainability?Sustainability can be achieved through careful resource management. By managing the resources and making proper use without wasting them ensures sustainability. The concept of sustainability demands careful and responsible people working towards a common goal of resources management.
A union is a term that refers to the association of workers of a company with the aim of defending and promoting their labor interests to the employer. The strike is a protest in which its members refrain from carrying out the activity they normally carry out to the detriment of those to whom they direct their claims.

15. Explain how it would be possible to have a change in a single base of DNA, but have the protein NOT change and be functional.
Answers
Answer:
Nonsense mutation. A nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.Sep 21, 2020

How does competition limit the dispersal of organisms? *
Answers
Answer:
Three factors that limit dispersal of a species are physical barriers, competition, and climate. Physical Barriers include water, mountains, deserts, and canyons because these barriers are hard for most organisms to cross, they limit the movement of organisms.
If an animal has to pass through another animals territory to disperse, that animal may be killed or injured in the process, so it may opt not to move or not to move as far as it should.

On average, an adult male sea otter weighs 36 kg (79 pounds), with some individuals weighing as much as 45 kg (99 pounds). A female weighs an average of 23 kg (50 pounds). To maintain their weight, otters must consume 250 kilocalories/kg of body weight each day to survive. Otters eat almost entirely small invertebrates for which they must dive to catch.
You have been tracking an adult female otter who weighs 25 kg. Answer the following questions based on the data provided.

Explanation:
25 x 250
The female otter which weighs 25 kg must consume a total of 6,250 kilocalories per day in order to maintain her body weight.
According to the illustration, otters must consume 250 kilocalories per kg of body weight in order to survive.
A female otter that weighs 25 kg must, therefore, eat 25x of the recommended kilocalories per kg daily in order to main her weight.
Thus: 25 x 250
= 6,250 kilocalories
