b) Ridge lines
c) Tributaries
d) Flood plains

Answer:

Explanation:

The common characters shared by frogs and pigeons are:

presence of jaws

four limbs  

The frogs and pigeons share these characteristics because they both are derived or evolved from a common ancestor.

During the course of evolution, the jaws are evolved in beaks in birds or pigeon as beak is light-weight in comparison to jaws.

Similarly, the forelimbs get covered with feathers to become wings.

Answer: D

Explanation:

Many unicellular organisms live in bodies of water and must move around to find food. Most often, they must obtain nutrients by eating other organisms. Plant-like protists, and some types of bacteria, can make their own food through photosynthesis.

Explanation:

Im not too sure about 3, but the others should be correct.

Answer:

Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point. Net evaporation occurs when the rate of evaporation exceeds the rate of condensation. A state of saturation exists when these two process rates are equal, at which point the relative humidity of the air is 100 percent. Condensation, the opposite of evaporation, occurs when saturated air is cooled below the dew point (the temperature to which air must be cooled at constant pressure for it to become fully saturated with water), such as on the outside of a glass of ice water. In fact, the process of evaporation removes heat from the environment, which is why water evaporating from your skin cools you.

Explanation:

Solar energy fuels evaporation in bodies of salt water. Evaporation happens in the Dead Sea and other bodies of salt water (like the oceans) as part of the water cycle.

Evaporation in bodies of salt water is fueled by solar energy from the sun. The sun's heat causes the water molecules in the surface of the salt water to gain energy and become more active. As the water molecules become more active, they gain enough energy to break free from the liquid and become water vapor, which rises into the atmosphere. This process is known as evaporation.

In bodies of salt water, the process of evaporation leaves behind salt and other minerals, which increases the salinity of the water. The high salinity of the Dead Sea and other saltwater bodies can also affect the evaporation rate, as the presence of salt can make it more difficult for water molecules to escape from the surface.

FALSE

Explanation:

Answer:

i think it would be A (aka the first answer)

Explanation:

im sorry if im wrong

Answer:

this is false.

Water is said to have a higher heat capacity than soil and stones, so the ocean takes much longer to heat and to cool than the land. ... Coastal areas have more moderate temperatures than landlocked areas because of the heat capacity of the ocean and hence the answer is false.

Answer:

False

because coastal areas have more moderate temperature.

The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium. The author cites a research study performed by scientists as evidence to support her claim. In this study, researchers planted two fields, each containing garlic mustard, and trillium.

The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium.

Trillium is a type of flowering plant that grows best in a partly-shaded, deciduous woodland habitat and along wet areas in the forest.

Deer is a herbivorous animals that feeds on the buds, blooms, berries, leaves, and even the stems of trillium.

Therefore, the main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium.

Answer:

Bond Formation

Explanation:

When a bond is formed, energy is commonly released as well as sometimes byproducts being formed. Many of the most common kinds of bonds are formed using water molecules or giving off water molecules.

Answer:

element

Explanation:

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.

Answer:

Explanation:

Answer:

b

Explanation:

Answer:

The amount of substance present in a certain sample can be calculated through the equation,

                      A(t) = A(o)(0.5)^(t/h)

where At is the amount now, Ao is the original amount, t is the number of years and h is the half-life.

For a substance to at most 50% of the original amount, we get the half-life value.

                   At/Ao = 0.5 = 0.5^(4.5/h)

h = 4.5 billion.

ok the answers are simple:
