An important part of photosynthesis is light thus the answer would be : <span>Sunlight provide light energy that allow photosynthesis to occur in plankton and aquatic plants.</span>
<span>(1) </span><span>Many assumptions gave rise to a mystery on Eastern island –why it has so slow growth of human population during the old times. The most common assumption read is that leader Rapa Nui, had greedily used up all the island’s resources leaving nothing for people to use and eat. The reason also why they fall to war and cannibalism. </span>
<span>(2) </span>Other factors that limit the growth population of an organism are:
<span>· </span>density-dependent factors like food supply, disease and pollution and density
<span>independent factors like freezing, weather, and drought. </span>
Answer: This is an opinion question so I will give you the facts so you can form your own opinion for this answer.
Explanation:
<u>PRO GMO:</u>
Manufacturers use genetic modification to give foods desirable traits. For example, they have designed two new varieties of apple that turn less brown when cut or bruised.
The reasoning usually involves making crops more resistant to diseases as they grow. Manufacturers also engineer produce to be more nutritious or tolerant of herbicides.
Crop protection is the main rationale behind this type of genetic modification. Plants that are more resistant to diseases spread by insects or viruses result in higher yields for farmers and a more attractive product.
Genetically modification can also increase nutritional value or enhance flavor.
All of these factors contribute to lower costs for the consumer. They can also ensure that more people have access to quality food.
<u>CONS of GMO</u>
Because genetically engineering foods is a relatively new practice, little is known about the long-term effects and safety.
There are many purported downsides, but the evidence varies, and the main health issues associated with GMO foods are hotly debated. Research is ongoing.
Some of the cons include: Allergies, Cancer, antibacterial resistance, and outcrossing which refers to the risk of genes from certain GMO plants mixing with those of conventional crops.
Answer:
No, it is not possible
Explanation:
Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.
This system is such that;
Type A can only have genotype: iAiA or iAi
Type B can only have genotype: iBiB or iBi
Type AB can only have genotype: iAiB
Type O can only have genotype: ii
According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).
Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)
