Answer:

The shape of a tree's leaves are a response to the tree species' long term ecological and evolutionary histories. ... A leaf must "capture" sunlight for photosynthesis (and as it does this it may also absorb a great deal of heat!) 2. A leaf must take in carbon dioxide from the surrounding air via pores (called "stomatae").

An example of a monosaccharide is ________.
Bad White [126]

Answer:

All of the above.

Explanation:

Monosaccharide may be defined as the sugars that are not further hydrolyzed or that do not give further sugars on hydrolysis. These monosaccharides are sweet in taste.

Glucose, galactose and fructose are monosaccharide sugars as they cannot be hydrolyzed further to give more sugars. These are colorless and water soluble sugars.

Thus, the correct answer is option (4).

A closed metal container that is filled with hot water gets distorted or compressed when it is kept under the tap water. Why?
tino4ka555 [31]

Answer:

Explanation:

The closed metal container will get distorted or compressed due to a combination of two reasons:

1.<em> contraction of the metal container as a result of a reduction in its temperature.</em>

2. <em>a reduction in the pressure inside the container caused by a sudden drop in the temperature of the water inside it. </em>

The tap water causes a reduction in the temperature of both the container and the water inside it. An increase in temperature causes metal to expand and a reduction in temperature causes it to contract. Also, water takes less space than steam. Therefore, a reduction in the temperature of the hot water causes a reduction in the pressure inside the container relative to the outside. This causes the metal container to be compressed.

marusya05 [52]
Monocotyledons:<span>Embryos have a single seed leaf, referred to as a cotyledon - hence the name mono (one) cotyledonLeaves have parallel venation and are generally strap-like in appearanceFlowers have petals and floral parts in multiples of threeIn the stem, vascular bundles are scattered and absence of vascular cambium explains absence of secondary growthA pollen grain with one openingRoot system is generally fibrous, shallow and adventitiousStomata can be found on both epidermal layers of monocot leaves. This condition is called amphistomaticExamples of monocot plants are: (grasses) most ornamental turf lawns, (bamboo's) ornamental and wild bamboo's inlcuding sugar cane, (grain plants) rye, rice, wheat, maize (bulbous plants) such as lilies, agapanthus, clivia, orchid varieties, most palm tree varieties</span>


<span>It should be noted that Monocotyledonous plants make up one huge slice of the worlds cereal/ edible crops, the staple diet of literally Billions of people and animals! </span>

 Dicotyledons:<span>Embryos have two seed leaves, referred to as cotyledons - hence the name di (two) cotyledon - although dicots now known as eudicots, most people still use the term "dicot"Leaves have branched venationFlowers have petals and floral parts in multiples of four or fiveIn the stem, the vascular tissue is arranged circularly and presence of vascular cambium explains ability to effect secondary growthA pollen grain with three openingsRoot system is generally branched, but taproot basedStomata can only be found in the lower epidermis. So, we describe it as hypostomatic conditionExamples of dicot plants include: (veg) tomatos, peppers, cabbage, beans, peas, (flowers) sunflowers, roses, daisies, violets, petunia, pansy (fruit) apples, pears, cherries, avocardo</span>
