Explain why offspring may or may not resemble either parent

2 answers:

7 0

as we have seen family's when mom looks very much like the children this is when the dominant genes were more connecting at birth. Another reason an offspring may look more like the mother than the father because she had the dominamt genes, and the father the recessive genes, dominant being coviring the recessive.

The offspring can have some features for the parents relatives and can look nothing like the parents. They can look exactly alike to more of one parent then the other or have features from both parents as well
Hope this helps :3

Why are unit of length mass and time independent with each other?

mariarad [96]

Масса (килограмм), длина (метр) и время (секунда) - это 3 из 7 основных единиц в системе СИ.

Базовые единицы произвольно определены как то, что они есть, поэтому они не могут быть получены.

Все другие единицы в системе СИ являются производными от 7 основных единиц, таких как скорость (метр / секунда).

Остальные 4 - это температура (Кельвин), количество вещества (моль), электрический ток (ампер) и светимость (кандела).

What is the passenger's apparent weight at t=1.0s?

Fittoniya [83]

Answer:

For the complete question provided in explanation, if the elevator moves upward, then the apparent weight will be 1035 N. While for downward motion the apparent weight will be 435 N.

Explanation:

The question is incomplete. The complete question contains a velocity graph provided in the attachment. This is the velocity graph for an elevator having a passenger of 75 kg.

From the slope of graph it is clear that acceleration at t = 1 sec is given as:

Acceleration = a = (4-0)m/s / (1-0)s = 4 m/s^2

Now, there are two cases:

1- Elevator moving up

2- Elevator moving down

For upward motion:

Apparent Weight = m(g + a)

Apparent Weight = (75 kg)(9.8 + 4)m/s^2

Apparent Weight = 1035 N

For downward motion:

Apparent Weight = m(g - a)

Apparent Weight = (75 kg)(9.8 - 4)m/s^2

Apparent Weight = 435 N

Rank in order the following according to their speeds, from fastest to slowest: (i) 425-nm-wavelength light through a pane of gl

kotegsom [21]

Answer:

v > ii > iii > i > iv

Explanation:

The speed of light does not depend on the wavelength of light rather the medium through which it passes through.

v) The speed of light in a vacuum is maximum = 300000 km/s

ii) The speed of light in air = 2999910.026 km/s

iii) The speed of light in water = 2255639.097 km/s

i) The speed of light in glass = 1973684.210 km/s

iv) The speed of light in diamonds = 1239669.421 km/s

Hence the ranking will be

v > ii > iii > i > iv
