Answer 1

Answer:

I can't identify the phenotypes since I don't know what trait B represents, what trait C represents and what trait c represents.

But you can find the phenotypic ratio by finding the number of individuals with each phenotype. The yellow squares are individuals that all have the same phenotype as each other. And the blue squares have the same phenotype as each other, but a different phenotype from the yellow squares.

The ratio would be written as:

(number of yellow squres):(number of blue squares)

12:4

does the earth need the sun to rotate on its axis ??

Answers

Answer:

An observer in space will see that Earth requires 23 hours, 56 minutes, and 4 seconds to make one complete rotation on its axis. But because Earth moves around the Sun at the same time that it is rotating, the planet must turn just a little bit more to reach the same place relative to the Sun.

Answer:

Yes, but actually no.

Explanation:

Since gravity pulls inward from all directions equally, a clump, if big enough, will eventually become a round planet. Inertia then keeps that planet spinning on its axis unless something occurs to disturb it.

To simplify, due to gravity, things will keep spinning until something stops it from spinning (this applies to being in space, I think).

in pcr,
a. the gene sequence is determined
b. multiple copies of the dna sample are made
c. dna is destroyed so it has no value

Answers

Answer:

b. multiple copies of the dna sample are made

Explanation:

Polymerase chain reaction (PCR) is a method used to make millions to billions of copies i.e. complete copies or partial copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it. The new fragments of DNA that are synthesize during Polymerase chain reaction (PCR) also serve as templates to which the DNA polymerase enzyme can attach and start making DNA. The result of this attachment in a production of huge number of copies of the specific DNA segment in a short period of time.

Which sentence uses supporting evidence to form the best conclusion about a rattlesnake?

Answers

C is the answer to the question

The sentence that uses the supporting evidence to form the best conclusion about a rattlesnake is as follows:

The rattlesnake's body temperature responded quickly to the environment, so it is an ectotherm.

Thus, the correct option for this question is C.

What are Ectotherms?

Ectotherms may be defined as the type of organisms that can not able to maintain their internal body temperature. They are also known as Poikilotherms. These types of organisms are absent on poles.

Due to a lack of internal maintenance of temperature, they can undergo hibernation and aestivation. Snakes and reptiles are ectothermic in nature. This significantly means that they directly obtain body heat from their environment.

Therefore, the rattlesnake's body temperature responded quickly to the environment, so it is an ectotherm is a sentence that uses the supporting evidence to form the best conclusion about a rattlesnake. Thus, the correct option for this question is C.

1. Compact, complex animals have internal exchange surfaces that are extensively branched or folded, providing a large _____________.
2. In the _____________, nutrients are absorbed across the many fingerlike projections of the lining of the intestine.
3. In the _____________, oxygen and carbon dioxide are exchanged across the epithelial linings of sacs at the tips of tiny air tubes.
4. In the _____________, wastes are removed from the blood across the epithelial linings of excretory tubes.
5. The _____________ transports materials between the exchange surfaces of other organ systems and body cells.
6. Body cells are bathed in _______________, and exchange between body cells and the blood takes place through this fluid.

Answers

Answer:

1.) Surface area

2.) Digestive system

3.) Respiratory system

4.) Urinary system

5.) Circulatory system

6.) Interstitial fluid

Explanation:

In higher complex animals, such as the vertebrates, the internal exchange surfaces are modified in such a way to facilitate the transfer of materials from cell to cell in the body. As animal size increases, diffusion distances increase and the ratio of surface area to volume drops. Larger organisms have had to evolve specialized systems that are made up of structures that provides a large surface area for internal exchange of materials. Examples of these systems include:

--> DIGESTIVE SYSTEM: The fingerlike projections of the lining of the intestine provide a large surface area for the absorption of nutrients.

--> RESPIRATORY SYSTEM: This ends with a sac called the alveolar sac. The anatomical arrangement of capillaries and alveoli produces a very large surface area that is available for gas exchange.

--> URINARY SYSTEM: wastes are easily removed from the blood across the epithelial linings of excretory tubes.

--> CIRCULATORY SYSTEM: transports materials between the exchange surfaces of other organ systems and body cells. An example is seen in the relationship between the alveoli and the capillaries surrounding it.

For any exchange of materials to occur between cells the fluid known as the INTERSTITIAL FLUID which fills the intercellular spaces allows dissolved materials to be exchanged between body cells and the blood

Alina notices that when she shines a desk lamp on a mirror, nothing happens.When she shines an infrared lamp on the mirror, the mirror starts to get warmer.Why does light from the infrared lamp warm the mirror when light from the desk lamp does not?

Answers

Answer:

Because the infrared lamp gives off a type of light that the desk lamp does not, and the mirror can only take in the energy from the infrared light.

Explanation:

Answer:

Explanation:

Infrared is used for incubators when a chicken egg is about to hatch. It is the electrical frequency of electromagnetic radiation the provides heat.

Because heat is produced electrically it can be controlled with something resembling a dimmer switch (the kind of switch that dims lights in romantic restaurants). That means that the temperature can be set to the hen's body temperature.

Infrared is just below visible light.
