Answer:
Which of the following factors contributes to the distribution of biodiversity on Earth?
Inter-species interaction contribute greatly to the distribution of biodiversity on earth as it gives room for migration which helps to increase biodiversity
Explanation:
Microscopes are one of the laboratory tools used to maximize the visual acuity of a certain specimen, it maybe a living or non-living organism or object. Thus, microscopes are widely used in these laboratories to increase microscopic observation with entities that cannot be perceived thru the naked eye. However, for scientisits to determine such specimen is a living thing if there's a presence of cell. Cell cannot be viewed via the visual organs alone but with the microscope a living specimen can be discerned with its characteristics such as cellular structure, slight and fidgety movement and other particular details..
The answer is A) That the seed eating species would disappear, because the seeds would disappear followed by the finches that ate those seeds and the other finches that eat other food like insects would thrive.
The complete question is :
The success of plants extending their range northward following glacial retreat is best determined by _____.
A) whether there is simultaneous migration of herbivores
B) their tolerance to shade
C) their seed dispersal rate
D) their size
Answer: The seed dispersal rate
Explanation:
The seed dispersal can be defined as the movement of the seeds away from the parent plant. The ability of the plant to extend is completely dependent on the ability of the plant to disperse its seeds.
Plants have very limited ability, they need vectors to carry its seed from one place to another.
The biotic and abiotic vector both are involved in carrying the seeds which helps in expansion of the trees.
hence, the correct answer is option C
Answer:
The thermometer can not be used to measure very low temperature
Explanation:
Mercury-in-glass thermometer is one of the types of liquid-in-glass thermometers.
Given the very melting point of mercury, it is unsuitable to attempt to use this thermometer for very low temperature measurement.
Hence, from the melting point of mercury, this thermometer can not be used to measure very low temperature.
