Answer:

True.

Explanation:

Light may be defined as the form of energy that allows us to see the objects. Light has the ability to undergo the phenomena like the reflection and refraction.

The formation of a shadow requires the under-lightning ( a source of light ). The under lightning results in the exaggerated facial features of the object and a deep shadows are formed during under-lightning.

Thus, the correct answer is true.

Topic: Enzymes and germinating seeds
Aleksandr-060686 [28]

Answer:

Testa,  Protect, Desiccation, Feezer, Two, Cotyledons, Embryo , Plumule, Radicle

Explanation:

Seed germination is defined as the process of growing of a seed that involves causing a seed to sprout.

There are three primary parts seeds embryo, endosperm and seed coat. The outer covering of seed is called Testa which is seed coat that protects the seed from desiccation and external harmfull condition of environment.

The seed are stored in freezer that keeps it dry and cool. A temperature between 32° and 41°F is ideal for storing seeds.

Seeds are dvided into two halves called cotyledons. The new plant germinating is called an embryo which has two parts named plumule and radicle. Plumule grows into stem while radicle grow sinto root under favuorable conditions.

Hence, the correct answer in the blanks are Testa,  Protect, Desiccation, Feezer, Two, Cotyledons, Embryo , Plumule, Radicle.

This sample of air at 35°C and 60% relative humidity holds ____ grams/cubic meter of water vapor. The same sample of air at 40°C
alisha [4.7K]

Answer:

Since a sample of air at 35 ° C and 60% relative humidity holds 26.25 grams / cubic meter of water vapor. The same sample of air at 40 ° C can hold a maximum of 50 grams / cubic meter of water vapor. If the air currently holds 30 grams / cubic meter, then its relative humidity is 60%.

Explanation:

To solve the following question, the following calculations must be performed:

If 40ºC can have a maximum of 50 grams per cubic meter of water vapor, this would imply a total of 100% humidity. Thus, if 35º had 100% humidity, the amount of grams per cubic meter of water vapor would arise from the following calculation:

40 = 50

35 = X

35 x 50/40 = X

1750/40 = X

43.75 = X

Now, if this implies 100% humidity, to determine 60% humidity the following calculation must be carried out:

100 = 43.75

60 = X

60 x 43.75 / 100 = X

2625/100 = X

26.25 = X

Therefore, if with 100% humidity you have 50 grams per cubic meter of water vapor, with 60% humidity you would have 30 grams of water vapor per cubic meter.

Gelneren [198K]

The presence of hydrogen bond is one factor that explains the fact that ice floats over water because it has less density.

Due to this, rivers and lakes freeze from the surface whereas it is in liquid state at the bottom which allows the sea animals to survive even in colder temperatures.

Water makes up at least 70% of earth and 65% of our bodies and this property of water is essential for our lives as it maintains the survival.
