What do desert plants not do so well?
Answer:
lack of water
Explanation:
Answer:
Hey mate.....
Explanation:
This is ur answer......
To survive, desert plants have adapted to the extremes of heat and aridity by using both physical and behavioral mechanisms, much like desert animals. ... Phreatophytes are plants that have adapted to arid environments by growing extremely long roots, allowing them to acquire moisture at or near the water table.

Earthquakes and faults form at __________ boundaries.
transform
convergent
divergent
Answer:
transform
Explanation:
Most earthquakes occur at the boundaries where the plates meet. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults, and subduction zones.

How does a chemical equation with coefficients relate to the law of conservation of mass?
A.The total mass must remain constant in a chemical reaction with coefficients in order for a physical change to occur
B.The number of atoms of each element must remain the same before and after a reaction in order for mass of the products to be the same as the mass of the reactants
C.The total mass of the reactants cannot equal the total mass of the products
D.The number of atoms in each element must change after the reaction in order for the mass to remain constant
DO NOT GIVE A LINK TO THE ANSWER PLEASE
Answer:
Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. ... Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation.

Answer:
A gene is a section of a double-stranded molecule known as DNA. This molecule is found within the nucleus of the cell, contained in threadlike structures called chromatin. The two strands form a double helix linked by a series of paired bases. The base adenine is always linked to thymine and the base cytosine is always linked to guanine.

Answer:
Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.
How do mountains affect the climate of a region?
(giving brainlist)
Answer:
As context, there are two sides of a mountain range:
A) The windward side
B) The leeward side
As mountains are tall, they block clouds which are in the troposphere. All the moisture thus falls onto the windward side, while almost none of the moisture from the rain gets to the leeward side.
In a nutshell, mountain ranges create barriers for precipitation which blocks off moisture to the leeward side, creating deserts.
This is why you see mountain ranges near deserts.
