Answer:
D. Commensalism
Explanation:
The relationship between a remora and a shark is an example of commensalism - it's good for one side but neither good nor bad for the other. The remora attaches itself to the shark and gets the benefit of eating the shark's leftovers, but there is no harm or benefit for the shark, and the shark doesn't eat the remora like in a predator/prey relationship.
Answer:
i think it is d. sorry if its wrong
The answer is C: The number of genes found in the nucleus
Answer:
It is given that a particle covers 10m in first 5s and 10m in next 3s. so using the equation of motion
Case I
s=ut+

20=10u+25a
4=2u+5a..............(1)
Case 2
In next 3s the particle covers more 10m distance. So
20=8u+

a(8)

5=2u+8a.........(2)
On solving equation (1) and (2)
4=2u+5a
5=2u+8a
a=

Put the value of a in equation (1)
u=

Now to find distance in next 10 s. total time will be 10s
s=

s=28.33m
Distance travelled in next 2 sec
s=28.33−20=8.33m
The correct answers are as follows:
1. The ECOSYSTEM-BASED approach considers humans as part of the natural resources management system.
There are many approaches, through which natural resources can be conserved and managed, one of these methods is ecosystem based approach.
Ecosystem based approach refers to a strategy that integrate the management of land, water and living resources. The method addresses many relationships across biological, spatial and organisational networks. This approach considers humans as an essential part of the natural resource management system.
2. This approach used SCIENTIFIC tools to manage resources.
The ecosystem based approach make use of appropriate scientific methodologies that are focused on level of biological organizations, which include processes, functions, structures and interaction of living organisms with their environments.
