Answer:</h2>
The correct answer is option D which is that endocrine control can control melatonin.
<h2>
Explanation:</h2>
As melatonin is released from pineal gland which is a part of endocrine system.The endocrine system is a chemical messenger system which has glands, which secretes certain chemicals known as hormones.These hormone acts on different organs to control different metabolisms in body.So melatonin which is hormone can be controlled by the endocrine system.
Answer:
The deposits truly depend on climate and the organisms from long ago that make fossil fuels <em>out of fossilized remains</em>. At that rate, the fuel will not be evenly distributed, rather split into some form of groups.

A. True ! Energy can be lost, but not created nor destroyed.
Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. The boundaries of an individual abiotic factor can be just as unclear as the boundaries of an ecosystem.These are often referred to as abiotic factors. Abiotic factors are non-living elements found within an ecosystem. There are six abiotic factors that affect plant growth: air, water, space, temperature, light and soil (nutrients).The two most important abiotic factors affecting plant primary productivity in an ecosystem are temperature and moisture.
LEARNING OBJECTIVE[ edit ]
Identify the abiotic factors that affect plant growth
KEY POINTS[ edit ]
Primary production, on which almost all of life on earth is dependent, occurs through either photosynthesis or chemosynthesis.
Annual biomass production, used to estimate net primary productivity by plants in an area, is directly influenced by an environment's abiotic factors, which include temperature and moisture.
Warm and wet climates have the greatest amount of plant biomass because they offer conditions in which photosynthesis, plant growth, and the resulting net primary productivity are highest.
TERMS[ edit ]
biomass
the total mass of all living things within a specific area, habitat, etc.
eco-region
a region, smaller than an ecozone, that contains a distinct biodiversity of flora and fauna
chemosynthesis
the production of carbohydrates and other compounds using the oxidation of chemical nutrients as a source of energy rather than sunlight; it is limited to certain bacteria and fungi
Answer:
Definition:
Biological evolution is the process through which the characteristics of organisms change over successive generations, by means of genetic variation and natural selection. It is most commonly defined as "changes in gene frequencies in populations."
A small change in genes could result in a mass epidemic. Such as the colinistists bringing yellow fever over to America.
Explanation:
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
