Answer:
Autotrophs
Explanation:
Food chain is a step by step feeding process in an ecosystem where an organism producer is been feed on by another organism that depends on it
called consumer and it is also feed on by predator. Producer usually produce their food its includes plants, Algae, phytoplankton.
The energy level moved from the producer to the last organism on the chain.
Autotrophs are the same as producer and an Algae food chain is an example of aquatic food chain where algae serves as primary source of energy(Producer) and its been feed upon by mosquito larvea and larvea by frogs and frogs are eaten by racoon.
Answer:
159.808 g/mol
Explanation:
Br itself is 79.904 g/mol. So multiply it by two.
Answer and Explanation:
During an experiment, data from an experimental group are compared with the data of a control group. These two sets are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals. This variable keeps constant in the control group.
The experimental group is the one that receives the experimental procedure, with changes in the independent variable. There can be several experimental groups.
In the control group, the variable measured keeps constant, not influencing the results. This isolates the effect of the independent variable on the experiment and helps to find alternative explanations to the different results.
In the exposed example:
- Control group: Certain amounts of fishes exposed to a normal number of light hours per day. For example, if under natural conditions in its original environment the species is exposed to 12 hour light, then the control group should be exposed constantly to 12 hours light a day to maintain its normal reproductive levels.
- Experimental group: Certain amounts of fishes, equal to the control group, exposed to a different number of light hours per day. For example, there might be 5 experimental groups: one of them exposed to 4 hours light, a second group exposed to 8 hours light, the third group exposed to 12 hours light (The same as the control group), the fourth group exposed to 16 hours light, and the fifth group exposed to 20 hours light.
Except for light, the rest of the variables should be the same for all the groups.

Explanation:
Answer:
The correct answer is 3rd statement.
Explanation:
A kind of sweat gland that discharges water from the surface of the body at the time of high internal temperatures are known as exocrine sweat glands. This water gets evaporates and results in the cooling of the skin surface. When the temperature of the body enhances, the sweat glands along with water also discharges electrolytes from the surface of the body.
The sweat glands also exhibit antibacterial properties, as they discharge dermcidin that interferes with the sticking of the microbes with the skin surface. The exocrine sweat glands do not secrete lipids, thus, they lack the tendency to condition the skin surrounding it. Hence, the given statement 3 is incorrect.
