Answer:

Twin studies document similarities and differences between twins. When two IDENTICAL twins raised under very DIFFERENT circumstances display similar personality traits, that suggests a strong GENETIC influence on personality. Critics of twin studies suggest that some documented similarities between twins are based on the fact that the twins are still the same age and may have some SIMILARITIES because of it.

Explanation:

It is not fully proved the genetic influence on the personality, and it is not the only factor wich modify the conduct.

It is stated that the personality is the result of a combination of different stimulus as genetic, socio-economic environment, parental education, upbringing rules, etc. Even the personal health can modify the personality.

It depends on the lens of the Anthony´s microscope, but It is likely that he saw artifacts

Explanation:

An optical microscope contains lenses of focal lenght that enable to see different structures. In this case, it is likely that Antony saw artifacts since living cells are not easy to focus with the optical microscope, it requires operator experience

Which of the following are some examples of rapid environmental changes? A) Succession B) Fires C) Weather D) Landslide​
kenny6666 [7]

Weather is an example of rapid environmental changes.

Explanation:

Environment refers to our natural world surroundings. Rapid means fast or quick. Weather around us keeps changing as the earth rotates and revolves around the sun. It changes depending on the month of the year or may change from day to night. You can also note the room temperature at different times in a day, it keeps changing mostly minorly but it does change. There are sunny, foggy, rainy, cold etc days and hence we can say that weather is example of rapid environmental changes.

A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur
mote1985 [20]

<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.

<u>Explanation:</u>

To calculate the weight of a person, we use the formula:

w=mg     ....(1)

where,

w = weight of an object

m = mass of the person = 65kg

g = acceleration due to the gravity of the planet

For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

g=\frac{GM}{r^2}

where, g = acceleration due to gravity = ?m/s^2

G = Universal gravitational constant = 6.67\times 10^{-11}Nm^2/kg^2

M = mass of the planet = 5.97\times 10^{24}kg

r = distance of the person from the planet = 6.38\times 10^6m

Putting values in above equation, we get:

g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2

Putting this value in equation 1, we get:

w=65kg\times 9.782m/s^2=635.83N

Hence, the weight of the person above the surface of a planet is 635.83N.
