A microwave absorbing device can be created to absorb the microwaves in the air from the communication signal plant or lines.
Cell phones or towers of cell communication, or towers can emit a frequency of 900 to 1800 MHz microwaves which are responsible for negatively affecting the health of birds.This have been proved that it can cause thinning of the skulls of the chicks and thinning of their egg shells which can reduce the population of local bird species. Thus the development of microwave absorbing device can help in reducing the negative influence of microwaves on bird species population.Learn more about microwaves:

Which term refers to the organism eaten by a predator?
A. Prey
B. Consumer
C. Herbivore
D. Decomposer
Describe the general flow of energy through an ecosystem beginning with the Sun and going through a third order consumer.
Answer:
1) Autotrophs transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) eat producers, make use of some of the energy, making from it their biomass.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy.
4) Decomposers (last order in the chain) recycle all the dead organic material and make use of some of the stored energy.
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.
From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.
Organisms that can use light, and turn it into organic matter according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, algae, and bacteria that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic web, heterotrophic organisms occupy the first, second, or third consumer level, after producers. There are different types of heterotrophic animals: carnivorous, herbivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.
At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
The progressive reduction of energy determines the number of trophic levels in the chain (4 or 5).
1) Autotrophs use water, CO2, and solar energy to produce O2 and glucose, by the process of photosynthesis and convert it into biomass. Producers transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) make use of some of this energy to survive, making from it their biomass. The rest of the energy is lost.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy. The rest of the energy is lost.
4) When different organisms die, decomposers (last order in the chain) recycle all the organic material and make use of some of the energy stored in their tissues. The rest is lost.

why is blood called tissue
Answer:
Blood has different types of cell.
Explanation:
Blood is called a tissue because it has different types of cells which have different functions. Blood has about 80% of water and 20% of solid part. This solid part is become solid due to these cells which are present in suspended in the liquid of blood is known as plasma. In this blood, nutrients are also present which reached to all the cells through circulation of blood.

A jar contains several different types of atoms. The proportions of these atoms can be changed slightly without changing any substance in the jar. This jar contains
Answer:
a mixture
Explanation: A mixture consists of different atoms that are not chemically bonded. It is of two types of the heterogeneous mixture and homogeneous mixture. The chemical substances can be differentiated visually in the heterogeneous mixture.
In a mixture, the proportion of atoms can be slightly changed without changing or modifying any substance. This is because the individual substances in mixture keep their properties when mixed together. Further, mixtures have variable compositions and substances. these mixtures can be are separated using physical methods.

Why might scientists study modern day organisms like birds to learn more about extinct organisms that lived millions of years ago?
because they have similiar genes? The modern organism were same species as them in the past, i think they just evolve
They share genetic traits. The current organisms were once members of the same species as them. It is believed they just evolved.
What is extinct organisms?A species is considered extinct when there are no longer any surviving examples of it anywhere on the planet. This can happen with both plants and animals. An organic byproduct of evolution is this. However, sometimes extinctions happen far more fast than usual. The primary contemporary causes of extinction include habitat destruction and loss, mostly due to deforestation, overexploitation via overhunting and overfishing, invasive species, climate change, and nitrogen pollution.
When there are no longer any living members of a certain animal or plant species anywhere in the globe, the species has become extinct. This is an organic byproduct of evolution.
Thus, They share genetic traits. The current organisms were once members of the same species as them.

21. This table classifies organisms into one of three domains. What is the
basis of this classification system?
Your answer
Answer: The table shows 3 domain Bacteria , Archae and Eukarya on the basis of the difference in sequence of nucleotide in the rRNA and cells lipid structure and its sensitivity towards antibiotics.
Explanation:
The three domain system was given by Woese and others. They classified the organism into three domain based on the sequence of the nucleotides in the ribosomal RNA and lipid structure (cell membrane) and its sensitivity towards antibiotics.
rRNA was useful for classification because they carry out the same function and its structure has a very little change over the period of time. So, by studying the dissimilarities and similarities in the rRNA we can compare how closely related the species are.
The lipid cell structure(some might contain peptidoglycan others might not) of these three domains are different and their sensitivity towards antibiotics are also different so, these characters combinely helps in classification system.

(just please complete the table above and answer it with respect)
Answer:
Compression is a reverse fault, tension is normal fault and shear is strike slip fault.
Explanation:
Compression is a reverse fault, tension is normal fault and shear is strike slip fault. Reverse fault is opposite of normal fault which occurs due to the stress of compression on an object in which both object come close together. Due to tension stress, rocks pulling apart from each other, produces a normal fault. Shear is strike slip fault because in strike-slip fault, the two blocks slide over one another

Explanation:
Which of the following is not true about water?
A Its smallest form is a molecule.
B It’s made of two different elements.
C It has the same charge throughout.
D It occurs both inside and outside of the human body.
Answer:
Im pretty sure everything but C is correct...
Water is a compound whose molecule is made up of two elements, namely hydrogen and oxygen. Because of the different atoms, the charge throughout is not the same. Thus, the correct option is C.
The molecule of water contains three atoms in total, two of hydrogen and one of oxygen. It is represented chemically as H₂O.
Because of the difference in the atoms, there is also a charge that is formed due to the difference in the electronegativity of oxygen and hydrogen atoms.
As a result. the electrons are more pulled towards oxygen andthus, oxygen has a more negative charge and hydrogen has a more positive charge.
Thus, the charge is not distributed throughout evenly. Thus, the correct option is C.
