As polar bears' population decrease, it creeps ever close to extinction This decrease in the population is due to loss of habitat (floating sea ice). This loss of habitat is caused by which of the following?
A. oil spills from ocean drill sites
B. human cities and houses being built in their habitats
C. Global warming
D. introduced can toads which are out competing polar bears for food

Answers

Answer 1
C. Global warming


Because of global warming the ice melts away but the polar bears need the icebergs in order to survive, without the icebergs the polar bears will lead to extinction. If global warming continues the ice will continue to melt and the polar bears won’t have any icebergs.

C. The sticky texture allows for pollen to adhere to the stigma for fertilization.
D. The sticky texture allows for water molecules to not escape from the plant, thus preventing dehydration.​

Answers

A-Most stigmas are covered with a waxy, sticky substance. This wet substance allows stigmas to provide an important service by re-hydrating dry pollen to prepare the grains to enter the ovary and initiate the process of fertilization.

Genetic variation is inherited by offspring.

A. Artificial aelection
B. Natural Selection
C. Both

Answers

Answer:

Both

Explanation:

A person's skin color, hair color, dimples, freckles, and blood type are all examples of genetic variations that can occur in a human population. Examples of genetic variation in plants include the modified leaves of carnivorous plants and the development of flowers that resemble insects to lure plant pollinators. Even though in artificial selection, you take which genes are desired it is still passing genetic variation through offspring.

Answer:

A bcoz it change the environment

Species A has the best chance of survival because it has the most genetic diversity.

What is genetic diversity?

Genetic diversity is defined as the set of different inherited traits that occurs within a species. Those organisms having higher genetic diversity have more chances of survival.

So we can conclude that Species A has the best chance of survival because it has the most genetic diversity.

What do all vectors and scalars have?

A. velocity
B. orientation
C. direction
D. magnitude

Answers

Answer:

D. magnitude

Explanation:

Scalars are quantities that are fully described by their magnitude (size) only. For example, a temperature is fully described by saying "80 degrees Celsius." We do not need to include a direction.

A vector contains both magnitude and direction. Acceleration is fully described by including both speed and direction: "45 m/s, North."

Both scalars and vectors have magnitude.
