In modern cosmology, the origin of the Universe is the instant when all the matter and energy that currently exist in the Universe emerged as a result of a great expansion.

<h3>Theories about the origin of the universe</h3>

  • may change due to further investigations

<h3>in astronomer proposed a new theory about the evolution of the universe what is the next step the astronomer should take to make his theory reliable</h3>

  • publish the theory in a scientific journal to let people know about it

<h3>where negatively charged particles would most likely be found in an atom</h3>

  • outside the core

With this information, we can conclude that Electrons – Negatively charged particles located in the electrosphere; Neutrons – Neutral charged particles that, like protons, make up the nucleus of the atom. The attraction or repulsion of bodies depends on the nature of the electric charge: Bodies with charges of the same nature (or sign) – repel each other.

irga5000 [103]

Answer:

a) 99.93%

b) 99.98%

Explanation:

Given that:

Total population size was only around 18 individuals ( for  black-footed ferret)

If the annual survival rate in the wild was 0.4%.

a)

What is the probability that all 18 would have died in a single year?

To find that; we multiply the annual survival rate in the wild with the total population; which is:

(0.4%×18) = 0.072%

Then; we subtract it from a total of 100% in order to determine the probability that all 18 would have died in a single year.

= (100.00% - 0.072%)

= 99.93%

b)

What is the probability that all 18 would have died in a single year if canine distemper was present?

Given that;

Because of the presence of canine distemper disease, the annual mortality rate might have been as high as 0.89.

To determine the probability; we have:

1 - Annual mortality rate = annual survival rate

1 - 0.89 = 0.11 %

Therefore, 0.11% of 18 individuals = (0.0011 × 18)

= 0.0198%

Probability that all 18 would have died in a single year if canine distemper was present = 100 - probability of annual survival rate

= (100 - 0.0198)%

= 99.98%

Answer:

In favourable environments you might find birds laying more eggs, and a greater likelihood of multiple successful clutches. There are also birds like Bald Eagles, that start mating in early January and can lay eggs before Spring officially comes. 13. Food Availability. The amount of food available has an affect on bird mating cycles.
