A, bacterial conjugation
Explanation:
I think it's this because in step 4, the things under the oval-ish circle looks like bacteria
The appropriate frequency for a cardiorespiratory endurance program is 3-5 times per week. The current recommendations for achieving cardiovascular fitness is moderate exercise around 3-5 times per week as this can achieve the highest level of sympathetic activity that can increase cardiovascular fitness without the consequential overfatigue that can result from exercise related injuries.
Answer:
Statement that best explains the importance of the root hairs to the stems and leaves of the plant is root hairs increase the surface area of the roots for nutrient and water absorption.
Explanation:
The options for this question are:
- <em>Root hairs convert minerals into glucose for immediate use by cells.
</em>
- <em>
Root hairs decrease the need for osmosis and diffusion in vascular tissue.
</em>
- <em>
Root hairs prevent water loss in leaves through transpiration and gas exchange.
</em>
- <em>
</em><em>Root hairs increase the surface area of the roots for nutrient and water absorption.</em>
The roots are organs of the plant that are responsible for fixing it to the soil, as well as allowing the absorption of nutrients and water.
In a germinated seed, the roots are the first to emerge, in the form of a radicle, to later become the primary root.
Since <u>one of the main functions of the root is the absorption of water and nutrients</u>, they have structures called root hairs, which are responsible for increasing the absorption surface, allowing the absorption process to be optimized.
Other functions of the root include being a reservoir of nutrients, establishing symbiosis with bacteria to obtain nitrogen from the soil and the nutrition of the soil itself.
