<h2>Diffuse co-evolution </h2>
Explanation:
The term ‘diffuse co-evolution’ was given by Janzen in 1980 to describe the idea that selection on traits often reflects the actions of many community members, as opposed to pairwise interactions between species
The idea was further clarified by Gould in 1988 by focusing on a variety of ecological and genetic mechanisms that might lead to diffuse co-evolution in response to selection from multiple species
Diffuse co-evolution as a whole can be defined as when selection imposed reciprocally by one species on another is dependent on the presence or absence of other species
In the given example panic grass can live only when the fungus protuberata is present and for Curvularia protuberata to colonize Curvularia thermal tolerance virus must be present so there is a web of multiple species where one species is dependent on other species and that other species in turn is dependent on different species hence referred to as diffuse co-evolution
A constant is something that is kept the same throughout the course of a experiment. So I would guess C) because they are not doing anything special. If it’s not C then it is A. :)
Answer:
C. exact same type of alleles
Weathering is the process by which rocks are broken down into smaller particles as a result of physical and chemical changes that are occurring in them. There are three major types of weathering these are: physical, chemical and biological weathering.
For the question given above, the type of weathering that is occurring in the picture of the given rock is PHYSICAL WEATHERING.
Physical weathering is the type of weathering in which the affected rock is changed in size and shape by means of some agents. The broken particles are usually of the same composition as the parent rock. The agents of physical weathering include: ice, plant roots, animal activities, abrasion and exfoliation. Physically weathered rocks are usually round in shape as a result of the abrasion process which they have undergone.<span />
Answer:
How hard the blood pushes on the inside of the blood vessels is called Blood Pressure
The total amount of blood the heart pumps in one minute is called Cardiac Output
When blood vessels open wider during exercise, they are said to dilate
How many times your heart beats in one minute is called Heart Rate
The force that can put unhealthy tension on the heart as it is pumping is called Blood pressure
The amount of blood the heart pumps out in one beat is called Stroke volume.
Explanation:
All this concepts to the heart and cardiovascular system. It is important to know how heart is functioning to see how blood circulates.
