Answer:
The nature of the indicated covalent bond is polar.
Explanation:
The given diagram is the Lewis structure of Methylamine which has the formula, CH₃NH₂.
In order to know that it is polar, we will discover that in the Lewis structure there are unpaired electrons in the central atom. Also, the bond that exists between the hydrogen and nitrogen shows that it is polar.
CH₃NH₂ is seen to have two charged ends that are opposite and the bonds that exists between hydrogen and nitrogen, which makes it a polar molecule.
The electronegativities of carbon, hydrogen and nitrogen can also be used to determine its polarity.

Explanation:
There are different forms of energy and one form of energy can be converted into another. When we light a wax candle, the process is highly exothermic and on burning, the chemical energy of the wax gets converted into heat and light. A good source of energy is to be selected for the choice of work to be done. In ancient times, wood was the most common source of heat energy. We, in our daily lives, use various energy sources for doing the work. Nowadays we use diesel and electricity to run trains. We also use fossil fuels in vehicles which has some serious disadvantages, mainly air pollution. The recent example of air pollution was ‘Smog’ in the National Capital Region of Delhi. This pollution was a result of burning ‘Parali’ in northern states of the country, which affected the eyes and also caused serious respiratory problems.

Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural selection in the field can be challenging. List at least three possible challenges Darwin might have faced.
Answers
Answer:
1. Darwin did not know how genetic material passed from one generation to the next because Mendel's laws of heredity had not yet been formulated
2. Finches have many phenotypic adaptations that can not be observed easily
3. Phenotypic traits are expected to evolve slowly, thereby taking many generations
Explanation:
In the Galapagos Islands, Darwin observed that there were many varieties of finches that showed variation in the size and shape of their beaks. Darwin determined that finches' beaks evolved in response to environmental changes (finches' beaks were different in different islands). Darwin had several challenges to make this discovery. First, Mendel's laws of heredity had not yet been formulated, thereby difficulting the analysis of quantitative traits (in this case, finches' beak) which are the result of the combined action of many genes and the environment. Second, finches (as well as all species) possess many phenotypic adaptations, thereby difficulting the study of single traits in an evolutionary context. Finally, phenotypic changes are gradual and therefore descendence with modification cannot be easily recognized by observation in the field.
Answer:
Traits other than beak type might affect natural selection.
It could take many generations to observe adaptions to a population.
The environment may be complex and hard to study.
Changes in the environment may occur faster or slower than changes to the birds
The birds may be interdependent with other organisms that may change, too.

how might the biotic and abiotic features change during different seasons?
Answers
Answer:
The biotic and abiotic features change during different seasons through various factors.
Explanation:
Biotic and abiotic factors are referred to as the living and non living components of the ecosystem respectively. An example of biotic factor include plants, animals and an example of abiotic factors are water, sunlight etc.
The biotic and abiotic features change during different seasons through various factors. Biotic factors in dry season for example will lead to a decrease in abiotic factors such as rainfall and increase in abiotic factors such as sunlight while leading to a decrease in biotic factors such as plants and animals through the lack of water vital for them.
Biotic factors in wet season for example will lead to a increase in abiotic factors such as rainfall and decrease in abiotic factors such as sunlight while leading to a increase in biotic factors such as plants and animals.

Scenario 1
When you think of the American Southwest, you probably think of cacti, both big and small. If you were to
visit the American Southwest today, you might be disappointed with the lack of variation among cactus
species, especially right off the major highways. In 1926, Route 66 was the nation's first major highway to
allow visitors to visit the Southwest. Like many tourists, these visitors wanted to take home a memento of
their travels. Many people would pull over and begin looking for their own living souvenir. Since many of the
tourists did not have the necessary tools to extract a spiny cactus out of the soil, they usually had to make a
conscious decision about what type of cactus they should dig up. The cacti with too many spines were seen
as too difficult to dig out, and the visitors likely didn't have gloves to protect their hands. The cacti with too
few spines were seen as homely and were often overlooked. Therefore, the tourists found a cactus that was
between these two extremes. Over the last century, the phenotypic variation within these small cacti has
changed (at least in areas accessible by these highways).

HIV can paralyses the immune system of a person infected by the virus.
Explain why.
Answers
Explanation:HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.

Explain how precipitation happens. Use complete sentences and give at least two supporting details.
Answers
Answer:
In a general aspect, humid and warm air moves to lower latitudes or in altitude, losing heat and getting colder. Its humidity condenses and causes precipitation. Depending on the air movement there are different kinds of rain.
Explanation:
At a global level, it occurs unequal warming of the atmosphere, which depends on many factors and varies with latitude. This occurs because solar radiation reaches the earth differently at different latitudes, resulting in big convective cells of atmospheric circulation: Hardley cell, Ferrel cell, and Polar cell.
A convective cell is the movement of the humid air among different latitudes. Air moves from higher latitudes to lower latitudes, getting warm, getting less dense, and ascending. As the air gets higher in altitude, it´s density and pressure decrease, so the air tends to expand with elevation in response to the reduced pressure. Gases in expansion experiment adiabatic cooling, losing caloric energy as their molecules move getting farther away from each other. As the air gets higher, it gets colder, and hence, denser. The result is that descends again. Humidity gets denser and precipitates.
• Rain is controlled by temperature on the earth´s surface, atmospheric global air circulation, the position of the mountains and oceans, closure to the oceans.
• There are different kinds of precipitations according to their origin.
i. Convective precipitation: These are the most typical ones. Air gets warmer and less dense, elevating in altitude with humidity. On the way, it starts to get colder, and the humidity condenses, resulting in precipitation. Depending o the degree of condensation, the precipitation might be in a liquid state (rain), semisolid-state (snow), or solid-state (hail).
ii. Frontal Precipitations: They occur when a polar front coming from higher latitudes collide with a warm front coming from lower latitudes, resulting in a strong rain. This is typical of grasslands or temperate forests (approximately 40 º latitude)
iii. Orographic Precipitations: They occur when humid wind ascends by a mountain range, causing its adiabatic cooling, condensing the humidity, and precipitating.

A section of one DNA strand has the sequence ACC GAG GTT. What is the sequence of the strand it binds to?
Answers
Answer:
UGGCUCCAA
Explanation:
Basically when you transcribe DNA into mRNA, you find the complementing base pair, for example if G is written in the DNA, the mRNA would show C, and if an A was in the DNA, a U would be shown. It is NOT THYMINE in RNA!! This changes to Uracil in RNA, and that is VERY important. The reason why it is flipped is because of the tRNA. So 3 mRNA nucleotides make a codon, and the tRNA are also in sets of 3, but are called anticodons. The tRNA is complementary to the mRNA strand, AKA the same as the DNA strand except with Uracil instead of Thymine. This is because Thymine breaks down in the presence of Oxygen and so is replaced by Uracil.
