D) allele frequencies of some traits change in the population
Alleles can be phenotype (how they appear) and natural selection is when an organism changes in a way that helps them survive.
It can be the way their beaks are formed that gives them a better chance of catching food among other stuff (Darwin's investigation)
Or how they change their color to adapt to the sudden change in tree coloration (Pepper moths)
the process Mitosis helps organism grow in size because Mitosis means the identical copy the cell creating 2 daughter cells. Then it keeps on growing.
The graph shows that the rate of photosynthesis increases with an increase in light intensity.
<h3>Photosynthesis and light intensity</h3>
Looking at the graph, the rate of photosynthesis is on the y-axis while carbon dioxide concentration is on the x-axis.
At low light intensity, the rate of photosynthesis increases with an increase in the concentration of carbon dioxide.
When the light intensity was increased from low to medium, the same trend as low-intensity light was recorded. However, the rate of photosynthesis doubles.
The rate of photosynthesis also increased with high light when carbon dioxide concentration increased. The photosynthesis rate was highest under intense light.
Under the 3 light conditions, it gets to a point that the rate of photosynthesis levels off, irrespective of the increase in the concentration of carbon dioxide.

B The products of respiration can be used by plants for photosynthesis.
Advances in machinery will expand the scale, speed, and productivity of farm equipment, leading to more efficient cultivation of more land. Powerful Seed, water saving irrigation, and better organic fertilizers will vastly improve the condition of agriculture, helping farmers increase yields.
The challenge which agriculture industry is facing is twofold :
Infrastructure must be developed to enable the use of connectivity in farming, and where connectivity already exists, strong business cases must be made in order for solutions to be adopted.
As connectivity increasingly takes hold, these new tools will enable new capabilities in agriculture:
- Massive Internet of Things. Low-power networks and cheaper sensors will set the stage for the Iot to scale up, enabling such use cases as precision irrigation, monitoring of large herds of livestock, and tracking of the use and performance of remote buildings and large fleets of machinery.
- Mission-critical services. Ultralow latency and improved stability of connections will build confidence to run applications that demand absolute reliability and responsiveness, such as operating autonomous machinery and drones.
- Near-global coverage. If satellites attain their potential, they will enable even the most remote rural areas of the world to use extensive digitization, which will enhance global farming productivity.
