g What are the three basic assumptions of Darwinian evolution? Group of answer choices Presence of phenotypic variation, some ph

enot [183]

Answer:

1- Presence of phenotypic variation

2- some phenotypic variation due to genetic variation

3- the given trait has an impact on fitness

Explanation:

The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.

C. At what height would the pomegranate have the same potential energy as the melon? (1 point)

zvonat [6]

Answer:

Given a set of assumptions which are given below, the height at which the pomegranate will have the same potential energy as the melon is 39.19 meters.

Explanation:

Gravitational Potential Energy refers to the acquired innate energy of an object due to its elevation above the surface of the earth.

This energy is the result of gravitational pull or force acting on the object.

In other to determine at what height a pomegranate and a watermelon will have the same potential energy we need to know the other factors in play.

Gravitational Potential Energy (Ep)= mgh

Where m = Mass (kg)

g = gravitational field strength (N/kg)

h = height (m)

Ep = gravitational potential energy ( j )

Let us assume that the

An average pomegranate weighs about 0.255146Kg

An average melon weighs about 10Kg
g is always constant at 9.8 N/kg

Note that melons weight much more than pomegranates.

So, let's calculate for the Ep of the melon at the height of 1 meter

Ep = 10 x 9.8 X 1 = 98j

Using the above assumptions, we do a goal seek using Microsoft Excel. Please see the attached image.

Calculation shows that the Height (h/Meters) at which the Ep of both veggies become equal is 39.19m

This can be verified by inserting the figure and multiplying it. It can also be calculated as follows:

That is

Ep = 98j

m = 0.255146kg

g= 9.8kg

h= ?

98= 0.255146 x 9.8 x h

98 = 2.5004308h (we divide both sides by 2.5004308 to make h the subject matter)

h = 98 / 2.5004308

h = 39.1932462198

Which is approximately 39.19

Which human activity has the lowest effect on global stability?

GREYUIT [131]

Answer:

I think the answer is C

''Reusing plastic bags''

Explanation:

Removing carnivores from a forest has a great impact on a environment since the population of the herbivores will increases drastically and the dynamic equilibrium of the area will be greatly effected.

If we look at choice B '' Heating homes with fossil fuels'', this will also have a big impact on the earth since fossil fuels are non-renewable and take centuries to form. Heating homes with them will result in loss of fossil fuels.

Now let's look at choice D ''Adding heavy metals to the water supply''. Heavy metals are dangerous to the human health and even cause cancer. This will cause thousands of deaths and will also have a great impact on the global stability.

This leaves choice C ''Reusing plastic bags''. This will cause less pollution and less harm to wildlife but doesn't have any big threat to the global stability. As in changing the world population or causing deaths in large numbers.

so I think choice C is the answer
