There are the answers for ur problems
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.
Answer:
The correct answer is - If you use the rooting hormone when cloning plants from cuttings, then it will be beneficial for the cuttings.
Explanation:
A hypothesis is a possible explanation or solution behind the particular natural world process or phenomenon. It is formed on the basis of the observation of the phenomenon or process, how it works or what characteristics it shows.
In this study, it is found that the root hormones promote the growth in the clonings from the cuttings of plants thus, the provided hypothesis is the correct hypothesis for the experiment given.
