B. white put became mix but cannot
Answer:
The answer is C
Explanation:
Based on the question telling us that we have a red snapdragon(RR) and a white one (WW)
Using a punnet square we can determine the phenotype of their off spring to be 100% Pink

Answers
Answer:
O Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals
Explanation:
Vestigial organs are defined as the organs which are no longer beneficial for survival.
Whales can be observed with tiny, unused hip and pelvis bones which are vestigial organs for them as they are no longer beneficial for their survival. The vestigial organs are the evidence of evolution in organisms and in whales also these vestigial organs says that whales and land-dwelling animals may have common ancestors. Later on with evolution some land-dwelling animals might move to water systems and hip and pelvis bones become vestigial organs for them which along with time decreasing in the future offspring.
Hence, the correct answer is "Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals".

Vegetarianism is often cited as a partial solution to the growing problem of deforestation and other types of habitat destruction as the human population continues to grow. The reason for this is
A vegetarians are healthier due to a lack of animal fat in their diets
B more people can be fed using less agricultural land because vegetarians eat at a lower trophic level
vegetarians consume fewer calories per person and therefore require fewer acres of farmland
D vegetarian diets often recommend consuming large amounts of tree nuts as a source of protein, which preserves forest habitats
E vegetarians often support conservation efforts that promote forest conservation
Answers
Answer:
Option B. is correct
Explanation:
Vegetarianism is the practice of abstaining from by-products of animal slaughter and the consumption of meat. Vegetarianism is often cited as a partial solution to the growing problem of deforestation and other types of habitat destruction as the human population continues to grow. The reason for this is more people can be fed using less agricultural land because vegetarians eat at a lower trophic level.
Option B. is correct
Statement that explains why vegetarianism is been regarded as partial solution to the growing problem of deforestation as well as habitat destruction is B: more people can be fed using less agricultural land because vegetarians eat at a lower trophic level.
Deforestation can be regarded as a destruction of the forest and wildlife as a result of human activities, and with the increase in population of people it tends to be on increase.However, vegetarianism can serve as a partial solution to this it will be easier to feed more people with small agricultural land which in turn reduce deforestation.Therefore, option B is correct.

5. Practice: Fill in the two processes that cause each of the following transitions.
A. Ocean -> Cloud
B. Cloud → Glacier
Answers
Answer:
Ocean to clouds:When warmed by the sun, water on the surface of oceans and freshwater bodies evaporates, forming a vapor. Water vapor rises into the atmosphere, where it condenses, forming clouds. It then falls back to the ground as precipitation. Moisture can also enter the atmosphere directly from ice or snow.
Cloud→ Glacier: The moisture then cools and condenses onto dust in the atmosphere to form clouds. Once in cloud form, this water will STAY in the atmosphere until it precipitates to the ground and collects in GLACIERS, LAKES, or OCEANS.
Answer:
A. Evaporation & Condensation
B. Precipitation & Freezing
Explanation:
A. From ocean to cloud --> The water on the surface of ocean must evaporate to form water vapor. Then the water vapor must rise to the atmosphere and condense to form clouds.
B. From cloud to glaciers --> The water in the cloud must precipitate to fall down to the ground as rain. Then the rain gets freezes to form glaciers.

Why would reaching the center of the Earth be difficult? In your opinion, could we one day reach the center of the Earth? Explain why or why not.
Answers
Answer:
At the very center of the earth is the inner core, a 760-mile-wide ball of iron. Seismic studies show that it consists of iron crystals that are kept solid by tremendous pressure even though it is hotter than the surface of the Sun.
The strength of gravity at the center of earth is zero because there are equal amounts of matter in all directions, all exerting an equal gravitational pull. With such thick air, you eventually lose momentum and stop your yo-yo motion about the center of the earth. You would end up stuck floating at the center of the earth.

Which two factors will increase the rate of a stream’s flow?
Answers
Answer:
Flood Erosion and Deposition: As flood waters rise, the slope of the stream as it flows to its base level (e.g., the ocean or a lake) increases. Also, as stream depth increases, the hydraulic radius increases thereby making the stream more free flowing. Both of these factors lead to an increase in stream velocity.
Explanation:
Flood erosion and deposition, as flood waters rise, the stream's slope rises as it descends to its base level, which may be an ocean or a lake.
What is the stream’s flow?Additionally, when stream depth rises, the hydraulic radius rises as well, increasing the stream's ability to flow freely, these two elements cause the stream velocity to rise.
The volume of water flowing into a stream channel from the watershed directly affects the stream's flow. The weather has an impact on it; it rises during downpours and falls during dry spells.
The force of gravity, which pushes water downhill, is what gives moving river water its energy. A river will flow more quickly and with greater energy at a higher slope.
Therefore, flood erosion and deposition factors will increase the rate of a stream’s flow.

Х Flag A lake borders a housing subdivision and a golf course. Over time, algae in the lake begin to grow uncontrollably. Which is the most likely cause of the algal bloom? A runoff of topsoil from construction on the golf course B runoff of nitrates from fertilizers applied to the golf course runoff of gasoline from roads through the golf course D runoff of animal waste from pets walked on the golf course
Answers
Answer:
B. runoff of nitrates from fertilizers applied to the golf course
Explanation:
Algal bloom is defined as the rapid growth of algae in freshwater or marine water. Algal bloom is green or yellowish in color that cover the top layer of water systems.
Algal bloom in the given case is caused by the excess of nutrients that is nitrates from fertilizers into waters and higher concentrations of nitrates causes uncontrollable growth of algae.
Algal blooms are harmful for environment as they may produce toxins and can block the sunlight from reaching the plants and animals in the water systems.
Hence, the correct answer is "B. runoff of nitrates from fertilizers applied to the golf course".

What would you expect the difference to be in the rate of diffusion of vinegar (molecular weight about 60) compared to oxygen (molecular weight about 32)?
Answers
Answer:
Vinegar has slower rate of diffusion due to higher mass.
Explanation:
The rate of diffusion in vinegar is slower than oxygen because of the higher mass of vinegar. Vinegar has molecular weight about 60 while on the other hand, oxygen has molecular weight about 32 so vinegar has more weight than oxygen which causes slow diffusion of vinegar from one place to another as compared to oxygen whose rate of diffusion is higher due to its lower weight.
