Answer:
- Soil knife to make digging the soil easier
- Handheld pruners to fix and prune the plants of your garden
- Gloves to keep your hands save from any harmful or chemical substance.
- Binder twine to maintain the plants (to tie their stems together)
- A notepad and pen to check the progress of your plants (e.g.: you might need to note down whether a plant may need more water or nutrients (mineral ions), if you see a plant almost wilting, appropriate actions must be taken so notepad and pen can help you track this down, so that you can get the appropriate resources needed)

Natural selection is the process by which an organism uses its traits to survive and reproduce. In this mechanism of evolution, organisms have favorable traits for survival and reproduction. The more adapted an organism is to its environment, the more likely it is to have heritable traits that are passed down to new coming offsprings, and really, this also applies for the likeliness of the organism to survive and reproduce in general. The more these heritable traits are passed down and used with offspring, the more common the favorable traits are in the community.
Answer:
b) contact transmission.
Explanation:
Contact transmission of pathogens occurs directly or indirectly between the source of the pathogens and the host organisms. During contact transmission by droplet spread, the pathogen is carried on smaller particles. These particles move through air for a very short distance, usually less than a meter. Therefore, droplet transmission of a pathogen requires that the source and host are present in close proximity.

trust
Answer:
The correct option is (D). The value of cardiac output in the case of the human heart is approx. 5 liters in a minute. The multiplication product of heart rate and stroke volume gives the cardiac output.
Explanation:
The blood flow serves as the parameter for the calculation of cardiac output. For the restoration of homeostasis, increase or decrease in the cardiac output leads to the simultaneous increase and decrease in the blood flow and pressure respectively. Also, the reduction of cardiac output and venous return signifies the higher value of the tidal volume. The associated parameters namely stroke volume and heart rate is also affected by certain factors. Some of them includes age, gender, contractility, heart size and duration of contraction.
Besides the flow of blood in the body depends on the oxygen requirement of the target cell.
