B
The answer is B because,If the the water concentration of sugar particles is greater than that of the medium(the medium is a hypertonic solution) the number of sugar molecules diffusing out will be more than than that entering and the cell will shrink and shrived due to osmosis
In terms of biodiversity, islands are special locations that contain a range of creatures and ecosystems for both native and endangered biodiversity. Endemism is typical of many islands. Thus islands are regarded as hot spots for biodiversity from a regional biodiversity viewpoint. In a collective portion of a basic land ecosystem it is much simpler to conserve species diversity than by shielding only one region of an archipelago.
Since every island has a specific variety of plants and animals, it is important that conservationists preserve the entire island chain. Thus allow the sources of food to differ from island to island in an archipelago. The type of producer originated in an island and then the type of consumers consuming it differ from island to island due to huge variety of and different adaptations of organisms.
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
- <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing
</em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>
Because the sun is closer to the inner planets and has more gravitational pull
These are coronary veins or any structure associated with coronary veins : b. Great cardiac vein, c. Coronary sinus
, & d. Middle cardiac vein. The great cardiac vein (GCV) is the largest of the veins draining into the coronary sinus from the myocardium. The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the heart muscle (myocardium). The middle cardiac vein commences at the apex of the heart; ascends in the posterior longitudinal sulcus, and ends in the coronary sinus near its right extremity. While jugular veins are any of several large veins in the neck, carrying blood from the head and face.
