3 0

Yes Carbon dioxide is necessary for photosynthesis because Photosynthesis didn't go on because there was no Carbon dioxide in flask X.

The carbon dioxide was absorbed by the sodium hydroxide. In flask Y, the colour of the iodine solution turned blue black. This is because starch was present in the leaf of flask Y. Starch was present because it underwent photosynthesis.

Nonrenewable resources are used much more prevalently today despite knowing that they pollute and will run out in the future. wh
KIM [24]

We are not using more renewable resources because we have been using fossil fuels since the 18th century and renewable resources are comparatively new. Also, we have limited knowledge about them, so it will take time to change our mindset toward renewable resources.

Based on exhaustibility, there are mainly two types of resources, renewable resources, and non-renewable resources.

Renewable resources are those resources that are replenished while non-renewable resources are those resources that are not replenished.

The non-renewable resources take millions of years to form and once exhausted they cannot be made more.

Examples of renewable resources are solar energy, wind energy, geothermal energy, etc. while examples of non-renewable resources are fossil fuels like coal and petroleum, metals, etc.

Despite the fact that the supply of non-renewable resources like coal and petroleum is limited and they also cause pollution, the use of them is rampant around the world.

The use of fossil fuels is widespread because we have been using them since the 18th century and the use of renewable resources is a very recent phenomenon.

Also, a major hurdle for using renewable resources is the upgrading of current technology to harness these resources.

The newer technologies are generally more expensive to employ, for example, the solar cells used for storing solar energy are made up of elements like silicon, silver, and gallium which are expensive.

What is the genotype of a male with red-green color blindness?
balandron [24]

Answer:

The genotype of male with red-green color blindness is XY, X chromosome possessing recessive allele of gene responsible for differentiating red-green color.

Explanation:

Color blindness is sex-linked trait and its inheritance follows criss-cross pattern. Dominant gene of allelomorpihc pair enables a person to differentiate between red and green color.

The genotype of male and female are different for the pair of sex chromosomes. Male is hetero-zygous (XY) and female is homo-zygous (XX). The gene controlling this trait is present on X chromosome.

Hope this helps (:
