Answer:

Explanation:

Photosynthesis is the process by which plants and some microorganism produce their food. In the eukaryote, the process occurs in the thylakoids ( light phase of the reaction) and stroma ( dark phase or calvin cycle). Some microorganism use infolding of the cell membrane which house chlorophyll to carryout photosynthesis. The energy gotten from sunlight is used through the combination of the light and dark phase reaction to produce glucose which is a monomer for other polymers such as cellulose ( cell wall production), starch (very essential for energy) and others. Cellular respiration involves several process of biochemical pathways such as glycolysis, kreb cycle and the electron chain that living organism use to harvest the energy from energy rich substances such as starch to drive their activities. The currency of cellular respiration is ATP. Cellular respiration is broken into two: aerobic which occur in the presence of oxygen and anaerobic does not require oxygen.

Cellular respiration in eukaryote organism occurs in the mitochondrial although part of it ( glycolysis) occurs in the cytoplasm. Prokaryotic organism lack mitochondria so they carry out cellular respiration in their cytoplasm.

It is accurate to say life on earth is solar-powered because a great number of living organism depend on sunlight to produce their food  (producer) and the oxygen produce for life. The process of the production yield extremely important product which are:

1. oxygen which without most living organism cannot survive because  energy rich aerobic process cannot occur and most living organism will die.

2. The food produce through sunlight is depended upon by greatly large group of organism who in turns convert it for other s and the conversion continue from level to level

xenn [34]

The missing part of the incomplete question is given below:

Which important step of scientific design is Shameka conducting?

repetition

replication

verification of results

using controlled variables

Answer:

Verification of results

Explanation:

The way toward gathering five examples of water from various sources is conveyed to confirm the outcome. By gathering water from five distinct areas of a similar source the analyst can genuinely find out the nature of the water in her region of remain.  

On the off chance that after examples are tried it is found the water isn't sound, the outcomes would be acknowledged as it has been appropriately checked and a  proper move would be made.

Thus, the correct answer is - verification of results

Use the techniques to find the unit for speed​
stellarik [79]

Answer:

The formula for speed is speed=<u>d</u><u>i</u><u>s</u><u>t</u><u>a</u><u>n</u><u>c</u><u>e</u>

time

Explanation:

to work out what the units are for speed,you need to know the units for distance and time.In this example,distance is in metres(m) and time is in seconds (s) , so the units for speed is metre per second (m/s).

miv72 [106K]

Answer:

T’= 4/3 T  

The new tension is 4/3 = 1.33 of the previous tension the answer e

Explanation:

For this problem let's use Newton's second law applied to each body

Body A

X axis

      T = m_A a

Axis y

     N- W_A = 0

Body B

Vertical axis

     W_B - T = m_B a

In the reference system we have selected the direction to the right as positive, therefore the downward movement is also positive. The acceleration of the two bodies must be the same so that the rope cannot tension

We write the equations

    T = m_A a

    W_B –T = M_B a

We solve this system of equations

     m_B g = (m_A + m_B) a

    a = m_B / (m_A + m_B) g

In this initial case

     m_A = M

     m_B = M

     a = M / (1 + 1) M g

     a = ½ g

Let's find the tension

    T = m_A a

    T = M ½ g

    T = ½ M g

Now we change the mass of the second block

    m_B = 2M

    a = 2M / (1 + 2) M g

    a = 2/3 g

We seek tension for this case

    T’= m_A a

    T’= M 2/3 g

   

Let's look for the relationship between the tensions of the two cases

   T’/ T = 2/3 M g / (½ M g)

   T’/ T = 4/3

   T’= 4/3 T

The new tension is 4/3 = 1.33 of the previous tension the answer  e
