what are formed through long periods of chemical weathering and erosion by water.
Answer:
Sometimes, chemical weathering dissolves large portions of limestone or other rock on the surface of the Earth to form a landscape called karst. In these areas, the surface rock is pockmarked with holes, sinkholes, and caves. The water transforms anhydrite into gypsum, one of the most common minerals on Earth.

The diagram above represents the phases of the moon. Position 1 represents the
new moon. Positions 2 through 8 represent the phases of the moon that follow.
Which phase does position 8 represent?
Answer:
waxing crescent
Explanation:
Position 8 represents waxing crescent phase. It is observed after a new moon and can be observed until the first quarter of moon.
What are the phases of moon?The waxing and waning nature of the moon is responsible for its various phases. This is due to the fact that moon is the only natural satellite of the earth. It revolves around the earth in a fixed orbit.
As earth revolves around the sun, the sunlight that falls on moon makes us visble those parts. Thus, it appears that moon is changing its shape.
A lunar month which is of 29.5 days usually is contains four primary and four intermediate phases. It is described as: New moon, Waxing crescent moon, First quarter, Waxing gibbous moon, Full moon, Waning gibbous, Last quarter and Waning crescent moon.
These phases have specific time in which they can be observed in the sky. New moon is an exception, as no part of the moon is visible then.
The phases of the moon are therefore considered as astronomically important.

Which one of these is not a human effect on the water cycle?
Developed areas prevent soil from absorbing rainwater
Precipitation is increasing in deserts due to an increase in water use
Air pollutants also wash back into the land and water bodies from precipitation
Storm water runoff carries pollution
Answer:
Precipitation is increasing in deserts due to an increase in water use
Explanation:
Just see for yourself
The one that is not a human effect on the water cycle is precipitation is increasing in deserts due to an increase in water use. The correct option is B.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
One of the most essential elements of human life is water. There is water all over. It passes through your house as well as rivers, mountains, lakes, and oceans. Without water, neither humans nor any other species could survive.
In the majority of deserts, the air's moisture content is very low. In the dry air, light raindrops frequently evaporate before they can reach the ground. Rainstorms can occasionally appear as ferocious cloudbursts.
Therefore, the correct option is B. Precipitation is increasing in deserts due to an increase in water use.

x x
1
2
Refer to the illustration above. Which of the cells will be a diploid cell at the completion
of division?
Both the cells will be diploid cells at the completion of division. Therefore, the correct option is B.
In diagram 1, the chromosomes are in the metaphase of cell division, that is aligned at the centre of the cell. In the next phase which is anaphase, these chromosomes are pulled apart by the spindle fibres in opposite directions. As a result, the chromosomes are split into half and each cell gets half the number of chromosomes in the form of chromatids. Thus, each cell will have 4 chromatids.
In diagram 2, the chromosomes are in the early anaphase stage. When the cell will split into two, each daughter cell will have 2 chromosomes. These chromosomes separate in the telophase and thus, each cell will have 4 chromatids.

Plants that are common to the temperate midlatitudes could also thrive in the tropics if they were grown at higher elevations. The effects of altitudinal zonation on plants and animals are unique to Latin America. Altitudinal zonation has had a strong influence on the types of native plants and animals found in the Andes and other mountainous regions. Only a few zones of the mountains may be used for some agricultural purpose. Altitudinal zonation makes it possible to grow many different types of crops.
Answer:
Due to different climatic condition.
Explanation:
Altitudinal zonation makes possible to grow many different types of crops because of different climatic condition of the region. Each and every plant has different climatic and environmental requirements due to which different plants can be grown on different places where environment is suitable. Some plants needs cool environment so they can be grown on high altitude while some needs warm temperature which can be grown on lower altitudes near the equator.

Which is a possible outcome for future generations of farmers if the same crop is planted on the same patch of land every year?
the soil could become infertile due to the lack of time for nutrients to be reinserted
the crops could become resistant to pests and insects through natural selection
the soil could become drought resistant due to the shallow root structure that would form
the crops could begin to change their genetic makeup due to mutations from the parent plants
Answer:
A
Explanation:
I hope this helps :)
The soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).
What is Soil?Soil is also defined as earth or dirt which is a mixture of organic matter, minerals, gases, liquids and organisms which together support life. These are distinguished from silt by restricting the former term specifically to displaced soil.
It provides many important services for both people and the planet by putting food on our plates, purifying our water, protecting us from floods and combating drought. Soil is also important in combating climate change because it captures and stores large amounts of carbon. Without healthy soil there is no food security.
Whereas growing the same crop year after year reduces the availability of certain nutrients and depletes the soil. Monoculture leads to soil exhaustion when the soil becomes deficient in these nutrients.
Thus, the soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).
