What are some of the phenotypic plant traits that scientists are investigating? Why do you think these traits were chosen?

1 answer:

8 0

The term phenotype in a more specific context to describe the collective expression of the genotype in conjunction with the environment on a plant's observable characteristics.

Explanation:

Phenotype, any of the measurable features of an organism arising from its genotype association (total genetic inheritance) with the environment. Behaviour, biochemical properties, colour, form, and scale are examples of measurable characteristics.
An allele is another type of one gene. A phenotype triggered by the expression of a gene or group of genes is the external manifestation of a human trait.
A trait is an attribute unique to an organism. The genotype's external expression is called the phénotype.

Need help with science pls help me!! 40 points

Answer: a. Regularly, you rub your hands for warmth.

b. Some examples are friction from electricity going through a wire or friction from rubbing your hand together.

c. Without friction, we would fall every time we walked. Because there is friction, we can walk normally. Another example is a ball moving across the field. Without friction, the ball would not slow down.

Explanation:

Overall, friction is important to us because we depend on it.

A tin can whirled on the end of a string moves in a circle because

Ilya [14]

Answer:

There is an inward force acting on the can

Explanation:

This inward force is known as Centripetal force and it is responsible for making the can whirl on the end of a string in circle and it is also directed towards the center around which the can is moving.

If all objects that have mass also have gravity, why doesn't your pencil get pulled towards you while it sits on your desk?

Lemur [1.5K]

Answer:

The pencil is not pulled towards a person due to a very small magnitude of force between them, due to lighter masses.

Explanation:

Let us apply Newton's Law of Gravitation between a person and pencil.

Average Mass of a Normal Pencil = m₁ = 10 g = 0.01 kg

Average Mass of a Person = m₂ = 80 kg

Distance between both = r = 1 cm = 0.01 m (Taking minimal distance)

Gravitational Constant = G = 6.67 x 10⁻¹¹ N.m²/kg²

So,

F = Gm₁m₂/r²

F = (6.67 x 10⁻¹¹ N.m²/kg²)(0.01 kg)(80 kg)/(0.01 m)²

F = 5.34 x 10⁻⁷ N

This Force is very small in magnitude due to the light masses of both objects.

Therefore, the pencil is not pulled towards a person due to a very small magnitude of force between them, due to lighter masses.

the formula relates the time, t, in seconds for a pendulum with the length, l, in feet, to make one full swing back and forth. w

Dovator [93]

This shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.

Given the formula for calculating the length of the pendulum expressed as:

$T= 2\pi\sqrt{\frac{L}{32} }$ where:

L is the length of the pendulum

T is the period of the pendulum

Given the following parameters:

Period T = 2.2 seconds

Substitute the given parameters into the formula will give;

$2.2=2\pi \sqrt{\frac{L}{32} }\\ (\frac{22}{6.58} )^2 =\frac{L}{32} \\L=3.5032 \times 32\\L = 3.92.71 feet$

So, this shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.
