4:
Independent Variable: Photosynthesis
Dependent Variable: Starch
Starch is a product of photosynthesis. Without photosynthesis, starch cannot form. Therefore starch is dependent on photosynthesis.
5:
Independent Variable: Temperature
Dependent Variable: Animal Metabolism
Animal metabolism will only be affected if the temperature of the room changes. Therefore animal metabolism is dependent on temperature.
9:
Independent Variable: Rainfall
Dependent Variable: Thickness of growth rings
The thickness of the tree's growth rings are determined by the amount of rainfall. Therefore the thickness of growth rings are dependent on rainfall.
Answer:
Mutations Are Recessive or Dominant
Answer:
winter
Explanation:
On this image, we can see the Earth being tilted away by 23.5 degrees from the Sun. This tilting puts the Northern Hemisphere in a situation where it is the one that is tilted away from the Sun, thus it will receive less sunlight, as well as less direct sunlight. That will cause lower temperatures on the Northern Hemisphere, thus the winter season will start, and it will last for around three months, at least at the mid-latitude zones. On the other side, the Southern Hemisphere is more exposed to the Sun during this tilting, so t receives more sunlight, and more direct sunlight, resulting in summer in this half of the planet.
Options for the question have not been given. They are as follows:
blood vessel length
blood viscosity
blood vessel diameter
blood colloid osmotic pressure
Answer:
blood colloid osmotic pressure
Explanation:
- Peripheral resistance is the resistance to blood flow by blood vessels.
- It is directly proportional to blood vessel length as more the distance to travel, more will be the resistance.
- It is also directly proportional to blood viscosity as more energy is required to push viscous material.
- It is indirectly proportional to blood vessel diameter. More the diameter of the vessel, easier it is for the blood to pass.
- However, it does not depend on blood colloid osmotic pressure. Colloid osmotic pressure is created by the protein components of blood and they do not have any direct impact on blood flow.
