Answer:
These mutualistic relationships are typically characterized by benefits to both the fungi and the plant that host them, with both benefitting at the same time.
Explanation:
Mutualism relationships are often characterized by a beneficial relationship between organisms. If one party benefits and the other doesn't benefit or the other doesn't really need the relationship, then that is not a mutualistic one.
Fungi partner plants for mutual benefits where the plant benefits and also reward the fungi. Two ways are explained below:
1. Fungi that live within plant tissues, produce toxins that affect animals that feed on the plant so limiting grazing, this activity tends to make the plant not overgrazed and protects the plant tissues. In turn for this favor, the plant rewards the fungi with nutrients to aid their continuous survival.
2. Mycorrhiza is a type of fungi found in plant roots and they are fed with most especially carbohydrates. So as they grow in population and thrive well they also reward the plant with the capacity to take up more essential nutrients from the soil which is very important for plants productivity.
Answer:
Oxygen comes from the lungs and blood carries the oxygen to body cells. (Blood flow or circulation).
Answer:
Galaxies rotate around their centers with the sections of the galaxy that are farther out from the galaxy's center rotating more slowly than the material closer to the center. Galaxies are also moving away from each other due to the expansion of the Universe brought on by the Big Bang.
Explanation:
Answer:
A. He has a large buildup of lactate in his muscles.
Explanation:
Ideally, our body cells, via the process of aerobic cellular respiration, need oxygen to break down glucose. However, during rigorous activities or exercises, oxygen can become unavailable for use. In this case, the body cells switch to use another way of cellular respiration, which is FERMENTATION.
This fermentation causes a build up of lactic acid/lactate (its byproduct) in the cells of the muscles being used, which physically causes a burning and aching sensation just as the case of this hiker. The climbing of the steep path is causing causing the fast usage of oxygen in his cells.
