This statistic displays the percentage of the variance in the dependent variable that the independent factors collectively explain. The R-squared statistic offers a simple 0–100% scale to express the degree of the relationship between your model and the dependent variable.
Variation refers to any distinction between individuals within a species or between populations of animals from different species. Genetic diversity is primarily brought about by mutation, but it is also influenced by other biological processes as sexual reproduction and gene flow. Linear regression is a linear strategy for modelling the connection between a scalar answer and one or more explanatory factors. When there is only one explanatory variable, simple linear regression is employed; when there are many explanatory factors, multiple linear regression is utilised.

Boats are able to stay afloat because of the force caused by...
a) gravity
b) hydraulics
c) viscosity
d) buoyancy
Answer:
d) buoyancy
Explanation:
Buoyancy can be defined as an upward force which is created by the water displaced by an object.
According to Archimede's principle, it is directly proportional to the amount (weight) of water that is being displaced by an object.
Thus, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.
The buoyancy of an object is given by the formula;
[tex] Fb = pgV [/tex]
[tex] But, \; V = Ah [/tex]
[tex] Hence, \; Fb = pgAh [/tex]
Where;
Fb = buoyant force of a liquid acting on an object.
g = acceleration due to gravity.
p = density of the liquid.
v = volume of the liquid displaced.
h = height of liquid (water) displaced by an object.
A = surface area of the floating object.
The unit of measurement for buoyancy is Newton (N).
Additionally, the density of a fluid is directly proportional to the buoyant force acting on it i.e as the density of a liquid decreases, buoyancy decreases and vice-versa.
Boats are able to stay afloat because of the force caused by buoyancy. This simply means that, a boat is able to float because the volume of water it displaces weigh more than its own weight. Thus, if a boat or any physical object weighs more than the volume of water it displaces, it would sink; otherwise, it floats.

In three to five sentences, describe the advantages and disadvantages using maps in modeling mitosis.
In biology, models can be viewed as representations, or perhaps events, of the structure and function of biomolecules. Cells have to do several things. First, cells must either replicate themselves or expand. In our human body, cells do both. It replicates when it breaks the skin and expands for the winter. However, some cells do not divide. But the cell also needs to decide whether to make identical copies or four half-copies. Half copies have sexual reproduction. And that's the choice between mitosis and meiosis.
The advantages and disadvantages of using these maps when modeling mitosis are:
They represented intermediate phases consisting of G1, S and G2 phases.
They also listed the stages involved in mitosis. this is also good
Other images also show mitosis, but lack potentially confusing titles or captions. The model should be able to represent the different activities that occur during mitosis. That is, the second model should contain markers that indicate the mitotic process.
The first models had to include pictorial representations for better understanding.

Do not spam and do not send out links (those who do will get reported)
Part (a)
Enter the data into your calculator or a spreadsheet. Then perform an exponential regression to find the curve of best fit. This is the closest exponential function we can assign to each population, to measure it's approximate growth.
Let functions f, g and h represent group 1 through 3 in that exact order. You should get these approximate functions:
f(x) = 6830.52397(0.92755)^xg(x) = 3969.81548(1.00295)^xh(x) = 5.67328(1.42775)^xNote: Group 3 doesn't have its population start until 1995, which is 10 years after 1985. This means h(x) only works when [tex]x \ge 10[/tex] or it's meaningless otherwise.
Each function found is of the form y = a*b^x, where 'a' is the initial population (at time x = 0) and b helps determine the growth rate. We set b equal to 1+r and solve for r to get the growth rate.
For f(x), we have b = 0.92755 approximately. Set that equal to 1+r and solve for r
1+r = 0.92755
r = 0.92755-1
r = -0.07245
The negative growth rate indicates we have population decline. Specifically, the rate of decline is about 7.245%
Repeat those steps for the b value of g(x) and you should find that r = 0.00295 meaning we have roughly a 0.295% increase for Mussel group 2.
Group 3 has a growth rate of about 42.775% due to r = 0.42775 in this case. The steps will be the same as for group 1.
=========================================================
Part (b)
The graph is shown below as an image attachment. I used GeoGebra to make the graph, and to also find the exponential regression equations.
We have x as the number of years since 1985, which is the starting point, and y is the population size. Something like (0,4800) means in the year 1985, the population is 4800 mussels (see group 1).
Keep in mind that the green curve for h(x) doesn't make sense for positive x values smaller than 10, due to the fact that the third group wasn't introduced until 10 years after the starting point of 1985.
Also, be sure not to think that the blue g(x) curve is linear. It looks like a flat line, but it's really a very stretched out curve. This is because the growth rate is very small.
=========================================================
Part (c)
It appears that group 3 has caused group 1's population to decline, due to the red points (see part b) going downhill as we move from left to right. This drop-off occurs at around the time group 3 is introduced. Strangely, only group 1 is affected while group 2's population is still increasing. This increase is not much, but it's still a positive growth rate. So it's fairly likely that there are other confounding variables to consider, and it's not entirely group 3 that's causing the trouble.
=========================================================
Part (d)
There are many ways that people impact their environment, whether it's a positive or negative impact. When regarding this topic of marine life, specifically mussels, one way that humans affect the population is what was mentioned earlier: The fact that the third group of mussels was introduced to the habitat. Often, though not always, if you introduce a new species to some environment, then the species of animals already living there may have a hard time coping with the newcomer. The new species would be referred to as "an invasive species". The invasive species is more aggressive at getting food to crowd out the older species that isn't used to the newcomer. This may explain why Mussel group 1 experiences a decline after 1995 when group 3 is introduced. This decline is fairly significant as the graph in part (b) shows. Group 2 doesn't seem to be affected at all since it's growth rate is fairly flat yet steadily increasing even if done slowly. It's possible that group 2 is simply more adapted to deal with competition better than group 1.
Another way humans impact the environment is through pollution. Air pollution may contribute to acid rainfall that would lead to the ocean. There's also chemical pollution such as flushing harmful chemicals down the drain, which also leads to the ocean. This could apply to the average consumer, or to very big industrial companies. For instance, in the news recently in Florida, there was a very big worry that a holding pond could contribute to a spike in algae growth. While algae are beneficial, there are some species that invade more than their fair share of resources and kill off anything else more or less. This is one example where pollution contributes to harmful consequences to unfortunate species who likely die off. On top of pollution, there's general habitat loss that also may explain why group 1 is experiencing a sharp decline (however it wouldn't explain why groups 2 and 3 are growing).
"BB" - this is described as what configuration?
BB is a dominant purebred condition in which only one character or trait is expressed, such as if it is for black, then only black will be expressed as there are two alleles present and both are similar.
What is the significance of the purebred traits?The term "purebred trait" refers to the presence of two dominant or two recessive alleles in genotypes such as BB and TT, and the parents with purebred traits inherit the gametes with a single type gene and no chance of variation is here.

Explanation:
Scientists discovered a fossil in China that belongs to a previously unknown species of an obscure group of small dinosaurs, related to primitive birds such as the famous Archaeopteryx. It had feathers, but they seemed too insubstantial to be useful in flight. Then the scientists said they recognized the unusually long, rod-like bone extending from each of the two wrists: curving structures possibly supporting an aerodynamic membrane. These scientists are grouping the found fossil with birds, based on ________ structures.
Answer:
Physical.
Explanation:
These scientists group the found fossil with birds on the basis of physical structures because first the scientists relate the fossil to the feathers of the bird and later the scientists relate it to the bone structure to determine the resemblance between the birds and the fossil of an obscure group of small dinosaurs so we can conclude that the scientists observe the found fossil on the basis of physiological characteristics of that fossil.

An emergent property of an ecosystem could be the fall colors enjoyed by many who travel to the northeastern and midwestern US deciduous forests. True False
False. An emergent property of an ecosystem is a property that arises out of the interactions between the components of the system, and is not attributable to any one component.
Rather, the fall colors are a result of the deciduous trees shedding their leaves in preparation for the winter. This is a seasonal phenomenon which is not characteristic of the ecosystem itself, but rather the individual species which exist within it.
The autumnal changes observed in the leaves of the trees, and the resulting show of vibrant colors, is a result of the trees’ response to the changing environmental conditions. The trees are adapting to the decreasing levels of sunlight, temperatures, and moisture, which occur in the autumn months.
The emergent properties of an ecosystem are more subtle and complex than the seasonal changes in the trees’ leaves. Such properties are the result of the interactions between the various living and nonliving components of the system, and can be seen in the ways that species interact and change over time.
This could include the way that species evolve in response to changes in their environment, the way that certain species are able to dominate the environment, or the way that resources are used and exchanged between species.
