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

In a city grid, each block on the east-west streets is 100 meters long. Each block on the north-south streets is 20 meters long.
alex41 [277]

Answer:

72.1 m

Explanation:

Hello!

When the walker walks west, each block he walks will be of 100 m, so the walker walked 4*100m = 400 m west.

Similarly, when the walker walks south, he walks 20 meters per block, therefore, the walker walked 4*20 m = 80 m south.

Since the directions west and south are perpendicular, the distance between the start ad end point is:

d = √(400^2 + 80^2) m = 407.92 m

However the walker traveled 480 m

Therefore, the walker traveled 480 - 407.9 m = 72.1 m farther than the actual distance

A piano tuner stretches a steel piano wire with a tension of 800 N. The steel wire is 0.400 m long and has a mass of 3.00 g. Wha
stepan [7]

Answer:

408.25 Hz.

Explanation:

The fundamental frequency of a stretched string is given as

f' = 1/2L√(T/m') .................... Equation 1

Note: The a steel piano wire is a string

Where f' = fundamental frequency of the wire, L = length of the wire, T = tension on the wire, m' = mass per unit length of the wire.

Given: L = 0.4 m, T = 800 N,

Also,

m' = m/L where m = mass of the steel wire = 3.00 g = 3/1000 = 0.003 kg.

L = 0.4 m

m' = 0.003/0.4 = 0.0075 kg/m.

Substituting into equation 1

f' = 1/(2×0.4)[√(800/0.0075)]

f' = 1/0.8[√(106666.67)]

f' = 326.599/0.8

f' = 408.25 Hz.

Hence the frequency of the fundamental mode of vibration = 408.25 Hz.
