The incidence of V. vulnificus infections is increasing, especially in northern parts of the United States, compared to 20 years

Korvikt [17]

Answer:

The effects of climate change may be associated with the increased incidence of V. vulnificus infection

Explanation:

Vibrio vulnificus is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. V. vulnificus is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of V. vulnificus infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of V. vulnificus infection.

Some orchids produce two types of flowers, one with only anthers and the other with only carpels. And on some orchids like this,

aliina [53]

Answer:

The Orchids is the diversified structures of flowers, in fact, they have unique feature. Even with the pollination, they have several mechanisms of pollination. Few of them include:

1. Few orchids have self-fertilization where the anther converts from solid-state to a liquid state without any aid of an external pollinating agent.

2. In others, self-pollination occurs, when the caudicles dry the pollen fall on the stigma.

3. This happens through an external pollinator resulting in a diversity of species.

4. This is a very special case where the flower attracts the insect to mate with bright petals, odor, and the shape.

5. These types depend on ants and other insects to get pollinated.

6. Here, the pollens release some kind of force, when an insect gets in contact with anther which results in getting away the agent from the flower.
