A model of a globe is a physical model. The limits are that the solar system is too big to be seen all at once. From the Tennessee science textbook, "Many years ago, scientists thought that Earth was the center of the universe and the sky was a blanket that covered the planet. Later through the observation, it was discovered that the objects you see in the sky are the sun, the moon ,stars, and other planets. This new model explained the solar system differently.
Answer:
The correct option is A. Inside of cell has more salt
Explanation:
When there will be more solute inside the cell than outside of the cell, then a concentration gradient will develop due to this uneven distribution. Water will move inside of the cell through a process known as osmosis. As the water molecules are moving along the concentration gradient, no energy will be used during this process.
The mechanism of osmosis is very essential in maintaining the turgidity of a cell.
Answer: Option D.
Genotype by environment interaction.
Explanation:
Genotype by environment interaction refer to a situation where two different genotypes react differently in an environment. Light skinned humans are at greater risk of skin cancer because they lack melanin which the dark people have and this melanin protect the skin from sun.
All the choices are correct. Differences in the norm of reaction I.e they react different way.
Epistasis is when the effect of a gene suppress the other.
Pleiotrophy is when a gene influence another genes phenotipically. These are all genotype enviromr interaction.
