Answer:
A. Circulatory system
Explanation:
Circulatory system consist of heart,blood cells&blood vessels
Given what we know, we can confirm that musk ox are affected by a lengthened warm season due to the fact that a lengthened warm season results in the shriveling of plants that musk ox eat. Without these plants, musk ox cannot survive.
<h3>What is the cause and effect relationship here?</h3>
- The effect, in this case, would be the endangerment of the musk ox population.
- This can be caused by a food shortage, as crops that are adapted to survive in winter climates would die off during a lengthened warming season.
- This, along with an increased number of parasites such as lungworms, which thrive in warmer conditions, would endanger the musk ox population.
- The most common cause of these conditions changing is global warming.
Therefore, given the fact that the disappearance of a steady source of food is often the prime culprit of a decrease in animal populations, we can confirm that a lengthened warm season results in fewer winter crops that the musk ox needs to survive.

The right answer is Mitochondria.
Answer:
The accessory pigments like carotene & xanthophyll necessary to have in green plants is chlorophyll
Explanation:
Various pigments present in the plants helps in the absorption of the light, at photosynthesis. They acts as helpers to the plants. Chlorophyll helps in the green plants for absorption of light through which they can prepare their own food. The electrons in the molecular level of chemical structure of the pigment moves at certain energy levels. The chlorophyll is again divided into different types i.e. chlorophyll a,b,c,d. In case of plants chlorophyll a and chlorophyll b are the most important.
Answer:
Genetic, geographic & cultural factors that cause sickle-cell anemia. It is important to note that even genetic diseases are caused by multiple social, environmental and biological factors. This is particularly true in the case of sickle-cell anemia, a genetically inherited blood disorder usually found in people with West African ancestry (PBS 2001).
