Answer:
Chlorophyll
Explanation:
because they lack roots, stems, and leaves.
Commensalism is a situation in nature where there is an association between two organisms that benefits one but does not help nor harm the other.
Let's go through each example in order to find one with commensalism.
A). Honey bees that feed on the pollen of cornflowers and help the flowers reproduce.
This is not a form of commensalism as both organisms mutually benefit from the association.
B). Barnacles ride on a gray whale's back to obtain food, and the whale is not harmed.
This is a form of commensalism. The barnacles benefit from riding on the whale's back as they obtain food. The whale is also unharmed in the process.
C). Squirrels and chipmunks eat the same nuts in a forest where food is scarce.
This is not a form of commensalism as neither organism benefits. There is an increased competition for food that harms both of the organisms.
D). Prairie dogs often collect and eat food in groups so they are better protected from enemies.
This is not a form of commensalism as the interaction of the organisms is within the same species. In order for commensalism to take place, two different species must interact.
The best example of commensalism is B.
As Myra needs to measure the gravitational force on the apple, a triple beam balance would be ideal to measure it.
The measure of the gravitational force on or near the Earth’s surface is its weight. This is the force of gravitation exerted by any object on Earth. Mass of an object determines its gravitational force. The force of gravitation or the measure of the weight is numerically equal to the product of mass of the object and the acceleration due to gravity on Earth which is constant having a value of 9.8 m/s^2.
Answer:
50% homozygous dominant, 50% heterozygous, 0% homozygous recessive
Answer: Saprophytic and parasitic
The fungi in general is a group of saprophytic as well as parasitic organisms that feeds upon the dead and decaying matter as well on the living organisms. These organism cannot prepare their own food by the process of photosynthesis like plants and other autotrophs but are dependent upon others organisms as well as dead matter for their food requirements.
