Answer:
B- Photosynthesis
Explanation:
Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.
Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.
Photosynthesis occurs in two stages:
- The light reaction stage
- The dark reaction stage
The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.
In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.
Answer:
9.0m and 0.009m
Explanation:
Since the hearing capacity range as from low to high. That is from 20Hz to 20000Hz.
F1 = 20Hz and F2 = 20000Hz
Also velocity is given as 360m/s
For the low capacity hearing
V = λf1
360m/s = λ × 20Hz
λ = 360m/s ÷ 20Hz
λ = 18m
Where λ = 2L
18m = 2L
L = 9m
As lo for the high frequency = 20000Hz
V = λf2
360m/s = λ × 20000
λ = 360m/s ÷ 20000
λ = 0.018m
λ = 2L
0.018 = 2L
L = 0.018÷2
L = 0.009m
<h2>C) is the correct option </h2>
Explanation:
To best convey the exact name of an organism to others in same field one should as a group, decide on an alternative that everyone understands
Names are important because they allow people throughout the world to communicate unambiguously about animal species because there are sets of international rules about how to name animals and zoologists try to avoid naming the same thing more than once, though this does sometimes happen
These naming rules mean that every scientific name is unique
The genus is the first level of taxonomic organization, in a way, because all species that are thought to be most closely related, are placed together in a genus
Scientific names are often descriptive also, suggesting something about the animal
Common names are not unique because of which it can lead to confusion about what animal is being referred to and what their relationships are to other animals
The medicare part B involves coverage for immunization, Seasonal flu, seasonal H1N1 flu, pneumococcal vaccine and Hepatitis B.
<u>Explanation:</u>
Medicare is a popular insurance coverage for elderly Americans that operates in 4 different modules the part A covers for inpatient expenses , part B covers outpatient expenses, the part C covers alternate medications and the part D covers medicine purchase for part C. All the coverage consists only commercially available vaccines. So the above given vaccines covers in the section of part B of Medicare.
The correct answer is: [D]: "all of the above" .
