Answer:
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Answer: The question is is incomplete, here are the options.
A. Separating the two groups decreases the chance that the two groups will diverge
B. Traits that form in one group from evolutionary forces quickly spread through both populations
C. Forces like natural selection and genetic drift affect the genes of the two subgroups differently
D. Gene flow is increased in the two subgroups that are formed
The correct Option is C.
C. Forces like natural selection and genetic drift affect the genes of the two subgroups differently.
Explanation:
Forces of natural selection and genetic drift affect the genes of the two subgroups differently because there are differences In the way they are natural selected and genetic drift.
Natural selection is the different phenotype or traits developed by different organisms who h make them to adapt, survive and reproduce than others in their environment. The two sub groups have different phenotype Expressed which cause them to develop different trait.
Genetic drift refers to change or variation in frequency of genes in animals overtime. Genetic drift occur at different rate in different population of organsim which lead to development of different trait in the subgroup.
Answer:
The correct answer would be - container 2 will have less salinity than container 1.
Explanation:
The given experiment can give an idea about how the temperature of surroundings can affect the salinity, volume, and density of the water that has the same amount of water and salt dissolved in it. The independent variable or the only variable that is different is their place that has a difference in the temperature. Container 1 is placed in a cool place while container 2 is placed in sunlight.
We know that the warmer the water it takes more space so, therefore, less density. Density and salinity both have a positive relationship so an increase in density increases the salinity and vice versa. Thus, here the salinity of container 2 would be low in comparison to container 1
Organisms that do not survive or adapt in Hurricane Sandy are seabirds like woodpeckers, shorebirds such as sandpipers, sea mammals like dolphins, creatures that are less salt-water such as crabs, minnows, marsh grasses, fish hatchlings. These are the few examples of the living organisms that were affected when Hurricane Sandy strikes.
