Answer:
They move from high concerntartion to low concertration
Explanation:
the diagram is not provided but am guessing there were bigger circles which could not pass through, which shows that the membrane was selectively permeable to smaller salt molecules. The movement across the membrane did not require energy.
Answer:
True
Explanation:
The slope of a velocity- time graph is obtained by dividing the average change in velocity over time.
slope=Δv/Δt
This gives the derivative of velocity with respect to time which is numerically equal to the acceleration.
Δv/Δt=acceleration.
Answer:
for each genotype, a range of phenotypes can be expressed
Explanation:
- The genetic makeup of an organism is referred to as the genotype of the organism and is responsible for determining the characteristics of an organism.
- The phenotype of the organism is the traits that are possessed by the organism by the expression of their genes however the phenotype of the organism is influenced by many factors.
- The various factors that influence the phenotype of the organism are :
1. Genotype
2. The environment that the organism lives in.
3. Stochastic developmental events
<em>Therefore, even though Emma and Anna were identical twins having the same genotype they had variability in their phenotypes because environmental and developmental events also influence the phenotype of the organism. </em>
Hybrids
The offspring of crosses between parents with different traits are called hybrids.
