Answer:
A plant based diet is clearly more nutritious. In fact, all protein orginates in plants. This is because it does not contain cholestrol, has very little amounts of fat, and is the only source of fiber. The science also bears this out. A plant based diet requires less recourses because it does not require the feeing of animals. The grain, fruit, vegtables, etc. goes directly to huaman, rather than being given to a imprisoned animals first. People should not only eat less meat, the should eat no meat. This is due to the three pillars of veganism. Ethics, envirnonment, and health. It is unethical to keep a animal in a cage it's short life and murder it. It is not envronmentally safe to raise trillions of animals a year all of whom produce methane, which is 16x more potent than CO2. And for health. It is increadable unhealthy to eat animal products. T. Colin Campbell has found a connection between cancer and dairy. Dr. Caldwell Esselstyn has found a undeinable link to heart disease. There are may more connections like this, which are very clear in their message: Humans can not handle the saturated fat, HEME iron, cholestrol, sugars, inflammatory substances, and everything else that comes with eating animals. Humans basic biology says we should not eat meat. We cannot murder animals with the tools that nature gave us.
Explanation:
<span>The birds with the longer beaks will be fittest in the environment post-drought because they will be able to gather resources (food) hence survive. This will enable these bords to reach reproductive again and pass down the genes. It is important to note that fitness in nature is determined by the capacity to reproduce.
</span>
<span />
<span>Natural selection will change the allelic frequency such that the allele for long neck will be more in the population while that of short beaks will reduce. This is because short beaks trait will not be able to reach reproductive age (due to starvation) because of the incapacity to gather food <span>resource hence their genes will keep reducing in the subsequent generations.

<span>Natural selection is a natural selective force that acts on a population and results to variation (differential) in the survival of the individuals in the population due to variations in phenotypes in the population. The most successful traits (phenotype that is best suited for the environment) are able to reach reproductive age, find a mate and reproduce hence leave its genes in subsequent generations</span>
For questions four plants make their own food which is oxygen gas. This oxygen gas, is an important part of the air, the gas that plants and animals must live on. When people breathe, it is oxygen that we take out of the air to keep our cells and bodies alive.
Answer:
1.States that organelles such as chloroplasts and mitochondria were once free-living prokaryotes which eventually lived symbiotically within larger cells, forming modern day eukaryotes.
2.Eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.
