Force applied?

4. A Woman Pushes A Stroller With A Force Of 8.2 N And Performs 28.7 J Of Work On The Stroller. Over

Answers

Answer 1

Answer:

3.5m

Explanation:

Given parameters:

Force applied  = 8.2N

Work done  = 28.7J

Unknown:

Distance through which the force was applied  = ?

Solution:

Work done is the force applied on body to move it through a particular distance.

 Work done   = Force x distance

 Now insert the parameters and solve;

          28.7  = 8.2 x distance

           distance  = 3.5m

9. Halobacterium has a photosynthetic membrane that is colored purple. Its photosynthetic action spectrum is exactly complementary the action spectrum for green plants. What wavelengths of light do the Halobacterium photosynthetic pigments absorb

Answers

Answer:

Yellow-green

Explanation:

Let us remember that the colour that is transmitted is always complementary to the colour that is absorbed.

Hence, if a substance absorbs a particular colour, it will transit the colour complementary to that absorbed colour.

The complementary colour of yellow-green is purple hence yellow green light of wavelength 560 - 580 nm is absorbed.

What is the function (purpose) of the valves which connect the heart chambers?

allows blood to flow between the two atria
allows blood to flow from the atria to the ventricle
prevents blood from flowing into the atria when ventricle pumps
allows blood to flow between the two ventricles

Answers

Answer:

allows blood to flow between the two atria

allows blood to flow from the atria to the ventricle

prevents blood from flowing into the atria when ventricle pumps

allows blood to flow between the two ventricles

prevents blood from flowing into the atria when ventricle pumps

The valves allow the blood to flow in only one direction so for example when the left ventricle contracts the mitral valve prevents the blood from going back into the left atrium.

Answers

it should be B 100% on that

A type of organism which consist of a group of cells without a specialized relationship between the cells is: (c) colonial.

A cell can be defined as the fundamental functional, structural and smallest unit of life, which is typically found in all living organisms.

Basically, all living organisms are broadly divided into two (2) main categories according to their cell type and these are;

Unicellular organisms: these are living organisms with a single cell.Multicellular organisms: these are living organisms that have multiple cells.

On the other hand, a colonial organism refers to an organism that comprises a group of cells that do not have a specialized relationship between them. Thus, colonial organism are made up of connected, interdependent group of cells.

In another population, the white spot allele frequency is 0.55. What percentage of the moth population has white spots?

Answers

Answer:

The correct answer is - 30.25%

Explanation:

Allele frequency in a population is the number of a particular allele in the population divided by the total number of all alleles present in the population for the particular gene.

The population has the allele frequency or q = 0 .55

So, the percentage of the white spots moth in this moth population would be -

q^2 = (0.55)^2

q^2 = 0.3025

q^2 = 0.0325 *100

= 30.25 %

WHICH choice refers to a single population in this image?

A The zebras

B The plants

C The animals

D The water

Answers

Answer:

would it be the plants

Explanation:

well all plants are the same and the animals there is more than one

In the given image, the zebras can be considered as the single population.  

• A single, living thing, which can be an animal, fungus, or a plant is considered as an organism.  

• On the other hand, a population is the term given to illustrate several organisms or individuals of a single species, which thrive in a specific geographical region.  

• The single population forms an entire species present in the given geographical location.  

• In the given figure, the group of zebras forms a single population, that is, if anything happens to that one population, the entire species will get vanished.  

Thus, the correct answer is option A, that is, the zebras.

Help!!! plz

Answers

Answer:

What color light is best absorbed by chlorophyll?

As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.

Explanation:

therefore it is blue

Answer:

Chlorophyll a: This is the most abundant pigment in plants. Chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). It reflects green light strongly so it appears green to us.

Explanation:

So in conclusion the answer will be Blue <3 Hope this helps!

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.

Answers

Answer:

See the answer below

Explanation:

Zara should keep Bozo in a separate salt water-containing tank away from the goldfish.

Bozo is adapted to living in salt waters. If it is kept in saltless water like the goldfish, its cells would lyse and the fish may die. The saltless water would be hypotonic to the cells of Bozo and water moves osmotically from a region of high water potential to a region of low water potential. Hence, the cells of Bozo would take-in water, become turgid, and may eventually lyse, leading to the death of the fish.

The goldfish cannot survive in salt water with Bozo because the water would be hypertonic to its cells. Hence, it will lose water to the surrounding salt water due to osmosis and may eventually die of dehydration.
