A scientist wants to observe the different bands of colors of light from a distant star. What device can the scientist use

Answers

Answer: Spectroscope

Explanation: Because a Spectroscope observes light.

The stars are the gaseous celestial illuminating objects. The stars emit a band of white light, which constitutes primarily of band of red, orange, yellow, blue, and green color bands.

The scientist will use the instrument spectroscope to view the different colors of light.

Astronomical spectroscopy can be defined as:

1. Astronomical spectroscopy is used to study chemical composition, measure the radiations of lights, infrared rays, X-rays, and radio waves.

2. The spectrograph measures the constituents of the stars and separates the light into corresponding wavelengths.

3. The spectroscope of the starlight produces a rainbow effect. The composition of different colors of the spectrum will help in the study of stars.

Thus, the scientist will use the spectrometer to study the wavelength of the different bands of light.

Organ system if that’s wrong then sorry but let me know ?

The brain, together with the neurological system that connects to it, is the most important organ system in the human body, even though your heart is also a key organ.

What is the role of body system?

Blood containing oxygen is delivered to your bones via your circulatory system.

Your bones are actively creating new blood cells in the interim. Together, these mechanisms preserve internal equilibrium and stability, or “homeostasis.”

The body's action and functionality are controlled by the neurological and endocrine systems.

The respiratory, circulatory, and digestive systems team up to eliminate waste from the body while simultaneously taking in essential nutrients and substances.

Therefore, connecting and supporting is primary function of body system.

Offspring sometimes look like their parents because??

Answers

Answer:

They inherit the genes from their parents

Explanation:

Answer: So children look like combinations of their parents because they are. Each parent gives half of their genetic material to their children. The combination makes a unique combination of their parents genes. The scientific study of how traits are passed from parents to children is called 'genetics'.

• Evaporation –

• Condensation –

• Precipitation –

• Transpiration –

• Crystallization –

• Downhill flow –

Answers

Evaporation: Vaporization that occurs at the surface of a liquid below the liquid's boiling point.

Condensation: The change of state from a gas to a liquid.

Precipitation: Rain, snow, sleet, or hail that falls from clouds to the Earth's surface.

Transpiration: The water evaporates from the leaves of plants and moves into the air.

Crystallization: the formation of highly ordered, solid structures from particles in a solutions.

Downhill flow: If precipitation falls on land surfaces, it always attempts to move back toward sea level as surface-water flow or groundwater flow

Answer:

evaporation is the process of turning liquid into vapor

condensation is the conversion of vapor to liquid

precipitation is rain snow sleet or even hail that falls to the ground

transpiration is the exhalation of water vapor through the stomata

What do osmosis and diffusion have in common?
A.) Both permit molecules of any kind, whether solute or solvent, to cross the bilayer membrane.
B.) Both require the additional energy provided by an energy carrying molecule, like ATP, to allow molecules to pass through the membrane.
C.) Both processes occur through a semipermeable membrane called a concentration gradient.
D.) Both are the net movement of randomly moving molecules that makes concentration nearly equal on both sides of a bilayer membrane.

Answers

Answer:

C.) Both processes occur through a semipermeable membrane called a concentration gradient

Explanation:

A. They only let certain things in and out of the membrane

B. They are passive transportors, meaning they do not use ATP or energy

D. They do not randomly move molecules. The concentrations are not equal. It should be from a high concentration to a low concentration.

Answers

Answer:

Its a recessive gene

Explanation:

It was passed down by their grandparents, or great grandparents

The two brown furred rabbits can produce white furred offspring if both parent stocks are heterogenous brown rabbits (Bb x Bb).

[tex]\frac{1}{4}[/tex] or 25% of the offspring will be white furred (bb) as shown in cross done with a Punnett Square (see attachment below for evidence).

Recall:

A recessive trait will be expressed in an offspring if two copies of the recessive genes for a trait are present in the offspring.

Let's assume the gene for brown fur is dominant over the gene for white fur.

Using B to represent gene for brown furb to present gene for white fur

Therefore, the two brown furred rabbits can produce white furred offspring if both parent stocks are heterogenous brown rabbits (Bb x Bb).

Explanation:

Answer: Color change

Explanation:

Why? Well, the evolution of, let's say, the peppered moth is a metamorphic case of steering color change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-colored moths increased at that time. Which is an example of industrial melanism.

What evidence have you discovered to explain how Mendel’s experiments showed that traits in offspring are inherited?

Answers

Answer:PLZ MARK ME THE BRANISET

By examining large sample sizes, Mendel showed that his crosses behaved reproducibly according to the laws of probability, and that the traits were inherited as independent events. Two rules in probability can be used to find the expected proportions of offspring of different traits from different crosses.

To find the probability of two or more independent events occurring together, apply the product rule and multiply the probabilities of the individual events. The use of the word “and” suggests the appropriate application of the product rule. To find the probability of two or more events occurring in combination, apply the sum rule and add their individual probabilities together. The use of the word “or” suggests the appropriate application of the sum rule.
