Answer:
avocado peaches lime and honey I think
Answer:
Look below.
Explanation:
A tertiary consumer is an animal that eat primary consumers and secondary consumers. From this knowledge we can conclude that the tertiary consumer is the mountain lion since nothing consumes the animal and it is on the top of the food web for consuming the most energy.
Answer:
The correct answer is - 10.6666 channels.
Explanation:
Given:
numbers of clusters duplicated = 16 times
The frequency bands for mobile unit transmission are - 825 to 845 MHz
The frequency bands for base station transmission = 870 to 890 MHz
The required bandwidth for each one-way direction of channels = 30 kHz
Formula:
the number of simultaneous communications that can be supported by each system = /
Solution:
The required bandwidth for each two-way direction of channels = 2 × 30 kHz
then, according to the formula the number of simultaneous communications that can be supported by each system
= /
k_{sys} = 16×40/60
[b_{ch} = (845-825) + (890-870) = 20+20=40)]
= 10.6666.
Answer:
The question is incomplete, the missing part i.e. the environmental change is:
(A) biomagnification
(B) acid rain
(C) eutrophication
The answers are:
1. Acid rain- Chemicals react with water and oxygen that enter water systems.
2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.
3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels
Explanation:
1. Acid rain is an environmental disorder in which rainfall becomes acidic due to pollution. The pollution is as a result of the release of gaseous chemicals e.g sulfur, nitrogen oxide, which are produced by industries, into the atmosphere. These chemicals then react with water in the atmosphere to form acidic solutions, which then falls back as rain. Hence, chemicals reacting with water and oxygen that enter water systems describes ACID RAIN.
2. Eutrophication is the pollution of water bodies with substances containing chemicals like nitrogen, phosphorus etc. The chemicals, which are in excess, serve as nutrients to algae, which uses them to grow excessively forming a bloom called ALGA BLOOM. Hence, nutrients in excessive amounts entering water systems, causing algal bloom describes EUTROPHICATION.
3. Biomagnification refers to the build up or accumulation of toxic chemical substances in the body systems of living organisms higher up in the food chain. Pollutants like pesticides, herbicides flow into water bodies and are absorbed by certain aquatic organisms. When these organisms are fed on by consumers, the harmful substances accumulates in their tissues until it reaches a maximum concentration. Hence, a high concentration of toxic chemicals present in the bodies of animals at the highest trophic levels describes BIOMAGNIFICATION.
Well, there's always camouflage.
