Red-green color blindness (c) is a recessive sex-linked trait. A colorblind male marries a normal female.

1 answer:

Sex linked traits can only be held on the X chromosomes, so males only need one while females need two. Since the daughter has it, it must mean the mother is a carrier and has one normal X chromosome and another with the recessive trait (c).

What is the period of a satellite in a circular orbit just above the surface of the Moon? The Moon’s mass is 7.36 × 1022 kilogra

Tanya [424]

Answer:

Explanation:

The satellite revolves around moon due to centripetal force which is provided by gravity in this context so we can equate gravity and centripetal force.

$mrw^{2} = \frac{GMm}{R^{2} }$

where, m is mass of satellite

M is mass of moon

ω is angular velocity

G is Universal gravitational constant

R is the radius of moon

from the above equation we get ω as,

$w=\sqrt{\frac{GM}{R^{3} } }$

$T = \frac{2\pi }{w}$

$T= 2\pi \sqrt{\frac{R^{3} }{GM} }$

here M = 7.36 X 10^22

R = 1.738 X 10^6

G =6.67 X 10^-11

$T= 2X3.14 \sqrt{\frac{(1.738 X 10^6)^{3} }{6.67 X 10^-11 X 7.36 X 10^22} }$

T= 6.50 X 10^3 seconds

Vlad1618 [11]

Answer:

Robert Hooke

Explanation:

Robert Hooke is an English scientist/biologist who in 1665 was the first to name CELLS after observing cork on a compound microscope he improved on. Robert Hooke published his discovery in his book titled: Micrographia.

Hence, according to this question where Nuris is writing a paper on the scientist who first named cells after studying cork. Her paper is obviously talking about ROBERT HOOKE who was the first to discover cells in cork.
