Water then moves from cell to cell through the root cortex by osmosisalong a concentration gradient; this means that each cell is hypertonic to the one before it. In the centre of the root the water enters the xylem vessels. Water may move by diffusionthrough the cell walls and intercellular spaces.
Answer:
One offspring would have red leaves.
Explanation:
Given
Yellow leaves are dominant and red leaves are recessive
Let us assume that the trait of Yellow color of a leaf be represented by "Y"
and the trait of red color of a leaf be represented by "y"
When two parent of genotype "Yy" are crossed with each other, the following offsprings are produced as shown in the punnet square below
Y y
Y YY Yy
y Yy yy
Total four offpsrings are produced out of which only one has red leave as red color is a recessive trait and it will appear only when both the allele in a cell are of red color.
Thus, one offspring would have red leaves.
Answer:
Ginkgos and Cycads
Explanation:
Gymnosperm plants such as Ginkgos and Cycads have flagellated sperm.
Answer:
Exponential growth and a type II survivorship curve
Explanation:
- Firstly we need to understand what exponential growth is, it is the type of growth in which population of any specie increases at a tremendous rate, constantly. In this type of growth, the increase is an exponential function of time for example, 2 reproduce to form form, four to sixteen and so on.
Population survivorship curves are simply the graphs representing increase in population with respect to time. There are three types of population survivor ship curve, Type I, Type II and Type III.
- <u>In Type II survivorship curve,</u><u> </u>there is a constant dying rate of individuals of population with respect to time.
Now lets come back towards question, where two characteristics of the population are mentioned,
- Exponential growth of a population of sparrows with each generation.
- Constant dying rate
<em>This clarifies that </em><u><em>Exponential growth and a type II survivorship curve</em></u><em> is the best option representing the said scenario.</em>
