The pit that marks the location of the umbilical cord after birth is known as the navel or belly button. All animals that grow placenta during fetal development will have a navel or belly button. The scientific name of the structure is the umbillicus. It can be a depression in some individuals or raised in others.
Answer:
A malaria outbreak causing allele frequencies to change is an example of <u><em>natural selection.</em></u>
Explanation:
Natural selection is a type of selection in which those organisms are favoured to live and reproduce which are better adapted to live in an environment. Due to natural selection, the allele frequencies of a population will tend to change with the passage of time.
When the outbreak of malaria occurs, those organisms which do not catch malaria are able to survive and pass on their characteristics to their offsprings. the other organisms die and do not reproduce. This will cause changes in the allele frequencies.
The question is <u>incomplete,</u> options are given below:
A. A tropical area with moderate rainfall
B. A temperate forest
C. A steep slope
D. A river delta
Answer:
<em>C.</em><em> A steep slope</em>
Explanation:
Erosion is a <u>weathering process</u> that causes removal of the top layer of sediments from any geological material (rock, plain area, etc) and then transports that material to another place. This process is governed by the combined action of wind, water (precipitation), gravity, and other meteorological parameters.
For this question, four options are given among which rate of erosion would be faster than the rate of soil formation for a steep slope. For a steep slope, the movement of water and wind would be stronger along with high gravitational pull as compared to the tropical area, river delta, and temperate forest. In principle, in the temperate forest, the erosion would be lowest due to the presence of plant roots that support the soil material to stay aggregated and resist against weathering.
North Atlantic Deep Water (NADW) is a deep water mass formed in theNorth Atlantic Ocean. Thermohaline circulation (properly described as meridional overturning circulation) of the world's oceans involves the flow of warm surface waters from the southern hemisphere into the North Atlantic.
