Redshift is an example of the Doppler Effect. As an object moves away from us, the sound or light waves emitted by the object are stretched out, which makes them have a lower pitch and moves them towards the red end of the electromagnetic spectrum, where light has a longer wavelength.
Answer:
The answer is false.
Explanation:
The red shift means that objects are moving away from the sun and Earth.

DRY MASS OF CORN SEEDLINGS GROWN UNDER DIFFERENT CONDITIONS
Initial Dry Mass of Dry Mass of10 Change in dry
Treatment Group Treatment 10 Plants (g) Plants After Mass of10 Plants
One Week () over One Week
I None 14.8
II Light 32.8 +18
III Dark 11.7 -3.1
Thirty corn seedlings of equal size were randomly assigned to one of three treatment groups. At the beginning of the experiment, the plants in group I were dried and the mass was determined. The plants in group II were maintained in light for a week. The plants in group III were maintained in the dark for a week. All conditions other than light, were the same for groups II and III. At the end of the week, the plants in groups II and III were dried and the mass was determined. The experimental results are provided in the table.
(a) To explain the increase in mass of the light-grown plants, identify ONE inorganic source of new plant mass and connect it to the cellular process underlying the increase in mass.
(b) To explain the decrease in mass of the dark-grown plants, identify the overall chemical reaction that is occurring in the plant cells and connect it to the cellular process underlying the decrease in mass.
Answers
Answer:
See the answer below
Explanation:
(a) One of the inorganic sources of new plant mass for the light-grown plants is the atmosphere. The carbon in the form of carbon dioxide in the atmosphere is sequestrated into the body of the light-grown plants through a process known as photosynthesis. During this process, the inorganic carbon dioxide becomes fixed into the body of the plant through a series of steps that include both light-dependent and light-independent. The overall equation of the process is as below:
[tex]6CO_2 + 6H_2O + Light --> C_6H_1_2O_6 + 6O_2[/tex]
As more plant mass is being gained by photosynthesis, some of the gained mass is also being lost to energy generation through a process known as respiration. Respiration is like the complete opposite of photosynthesis but a gain in mass is still possible because the rate of photosynthesis is more than the rate of respiration in the light-grown plants.
(b) The chemical reaction that can be held responsible for the decrease in mass of the dark-grown plants is respiration. Some of the mass is lost to energy generation and this mass cannot be recouped by adequate photosynthesis due to light limitation. The energy is needed to metabolic processes that would keep the plants alive. The equation of respiration is as below:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + Energy[/tex]
Answer:
A) Inorganic source of cellular mass is CO2. Plants take up CO2 from the atmosphere. By the process of photosynthesis, plants prepare sugars . Sugar gets converted in to starch, cellulose and other carbohydrates which are stored in the cells of the plants. This increases the plant mass . Plant requires water,CO2, light chlorophyll.
Chlorophyll absorbs sun light and converts it in to chemical energy. Chemical energy is used by the plant to synthesize sugars. Because of the synthesis of the sugars ,starch etc , the mass of the plant increased. Plants need light for making sugars.
B. Decrease in the mass is due to cellular respiration. This group of plants are in dark. So they do not photosynthesis.
But they have to undergo respiration to get energy for the activities of the plant. So no photosynthesis is occurring, hence no sugar formation. But sugar present in the plant is consumed to release energy. That is why mass of the plants kept in dark is reducing.
Cellular respiration has 3 steps. 1. Glycolysis 2. Kreb's cycle. 3. Electron Transport Chain.
The cellar respiration provides energy to all living organisms.
[tex]C6H12O6 + 6 O2 ---------> 6CO2 + 6H2O + energy (ATP)[/tex]
CO2 released is given out of the plant body. So this is reducing the plant mass.

a sound wave with a speed of 346 meters per second has a frequency of 30.025. What is the wavelength of this wave?
8.4 waves go by in 6.875 seconds. Calculate the frequency (per 1 second).
Answers
Answer: 4.4; 10,339; 0.145
Explanation:
F = c/L f = frequency, c= wave speed L = wavelength
1. 2.364 = 10.4045/c, c= 10.4045/2.364 = 4.4
2. 30.025 = L/346, L = 30.025*346 = 10,339
3. period of the wave 6.875/4 = 1.72 and f= 1/period = 4/6.875 = 0.145

A. Dehydration
B. Acidization
C. lonization
D. Hydrolysis
Answers
Answer:
Dehydration, sorry if its wrong
Explanation:
Hydrolysis is happening in the reaction. Hence the correct option is D.
Hydrolysis is a chemical process that involves the breaking down of a compound through the addition of water. During hydrolysis, a water molecule splits into hydrogen and hydroxide ions, which participate in the cleavage of the chemical bond within the compound, resulting in the formation of two or more new substances.
Hydrolysis reactions are found in various natural and synthetic processes. In the context of biomolecules, such as proteins, carbohydrates, and fats, hydrolysis plays a fundamental role in their digestion and utilization. In industrial processes, hydrolysis is also employed to break down complex molecules into simpler components.
Hence the correct option is D.

Answers
Answer: the 1st one
Explanation:
A grassland predator and prey, such as a cheetah and a zebra. Therefore correct option is (A).
What organisms have common adaptations?The pair of organisms that is most likely to have adaptations in common is a pair of organisms that share similar environmental pressures or ecological niches. Organisms that occupy similar habitats, have similar diets, or face similar challenges are more likely to evolve similar adaptations over time.
For example, predatory animals such as lions, tigers, and leopards have evolved similar adaptations such as sharp claws, powerful jaws, and keen senses to help them catch prey. Similarly, desert-dwelling animals such as camels, kangaroo rats, and fennec foxes have adaptations such as the ability to conserve water, tolerate heat, and dig burrows in sandy soil to survive in their arid environments.
