Why do leaves appear green?

s2008m [1.1K]

<u>Answer:</u>

The correct answer option is B. Green wavelengths are the least used in photosynthesis.

<u>Explanation:</u>

Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.

From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.

Therefore, this reflection of green light makes the leaves to appear green.

He portion of the membrane that faces the lumen is called the ________ membrane.

irina1246 [14]

The portion of the membrane that faces the lumen is called the apical membrane.

Membrane is the lipid bilayer that surrounds the cell on its outer surface. The membrane serves various functions like: protection, cell shape and integrity and regulate the traffic of molecules across the membrane. It is semi-permeable in nature.

Lumen is the hollow portion present inside any organ or tube like the artery or intestine. It is a Latin word that means 'an opening'. The lumen of different organs served various purposes. However, the major function is the transport of substances like air, nutrients, waste materials, immune cells, hormones, etc.

How would shoot and root growth be affected by a mutation that caused plants to lose the ability to polymerize glucose into star

Anastaziya [24]

Answer:

b) Lateral branch shoots would grow more horizontally and have less of a tendency to turn upward.

d) Lateral branch roots fully embedded in soil would grow randomly upward and downward.

e) Roots breaking the soil surface would grow upward.

Explanation:

Inside the amyloplasts of the common bean the starch granules resemble variously sized cotton balls stuffed into a balloon. Under normal circumstances amyloplasts do nothing more than sit on the bottom of special gravity-sensing cells. When a plant is knocked over, the amyloplasts slide from what was recently the bottom of the cell onto a formerly vertical wall. Somehow, this movement is sensed and relayed to cells that secrete the growth-regulating plant hormone auxin.

Since the plant has lost the ability to transform glucose into the granules. The plant can´t differentiate between up or down because gravity is what causes these granules to settle down.

In the figure below, ΔMNO≅ΔPQR.What is the measure of ∠P? Show your work and explain your reasoning.

Juliette [100K]

Answer:

$\huge\boxed{\sf P = 79.5\°}$

Explanation:

<u>Given that:</u>

ΔMNO ≅ ΔPQR

That means

M ↔ P

N ↔ Q

O ↔ R

So,

∠P ≅ ∠M

Given that P = 3x + 20.4 and M = 5x - 19

3x + 20.4 = 5x - 19

Add 19 to both sides

3x + 20.4 + 19 = 5x

3x + 39.4 = 5x

Subtract 3x to both sides

39.4 = 5x - 3x

39.4 = 2x

2x = 39.4

Divide both sides by 2

x = 19.7

<u>Given that:</u>

P = 3x + 20.4

P = 3(19.7) + 20.4 (x = 19.7)

P = 59.1 + 20.4

P = 79.5°

A student notices that her guppies reproduce most when her fish tank water is slightly alkaline. They stop reproducing if the wa

Gnom [1K]

Answer:

The correct answer is Zones of tolerance

Explanation:

All living organisms such as fish,plants and animals need water to survive and also the require certain pH level of water in order to be healthy.Its a acid and base balance reaction.Strong acids dissolve into water and its changes water's pH.if water's pH level drops it becomes acidic suppose a fish waste ammonia releases and dissolves in water to form harmless ammonia ions,carbon dioxide ions and hydrogen ions even some limestone also rises pH level and water becomes more basic.To make the tank water alkaline, add some corals and aerate the tank water by fixing an air pump so that excess of carbon dioxide eliminate out and water pH level comes to neutral this is the reason water becomes slightly alkaline and the fishes are able to reproduce.
