The source of a sound moves away from the listener. Listener has the impression that the source is ________ in pitch and the frequency has_______.
A.) lower. Increased
B.) lower, decreased
C.) higher, decreased
D.) higher, increased
Answers
Doppler Effect is defined as the change of frequency of a sound or light wave produced by a moving source and a stationary observer. The waves when they move towards the object compresses.
The correct answer is:
Option B. lower, decreased
The Doppler effect can be explained as:
1. The listener will have the impression that the moving source is higher in the pitch as it moves away from the listener.
2. The frequency of the waves will be decreased because the time between the successive sound waves is lengthened or increased.
Therefore, the pitch will be lowered and the frequency will be decreased.

Answers
Oxygen usage is NOT a characteristic of life.
Cellular respiration is the metabolic pathway by which aerobic cells can produce energy by using the energy stored in the chemical bonds of foods in presence of oxygen.Conversely, there are organisms capable of fermenting foods in anaerobic conditions to produce energy in the form of ATP.Moreover, all organisms are composed of one or more cells and they carry out metabolic functions (i.e., reproduction, growth, differentiation, etc).In conclusion, oxygen usage is NOT a characteristic of life.

In a multicellular organism, the lungs are responsible for exchanging gases with the organism’s environment. Which cellular structure performs the same task for a cell?
Answers
Answer:
This question lacks options; the options are:
A) chloroplast
B) mitochondrion
C) endoplasmic reticulum
D) plasma membrane
The answer is B. mitochondrion
Explanation:
The Lungs of multicellular organisms, as described in this question, is a respiratory organ that is involved with the INTAKE of oxygen needed for cellular respiration and EXPULSION of carbon dioxide out of the body, a process called GAS EXCHANGE.
This gaseous exchange function of lungs is carried out for the process of respiration which is carried out at the cellular level by MITOCHONDRION. Mitochondrion is an organelle in eukaryotic cells associated with the cellular respiration (release of energy).
The gaseous reactants (oxygen) and products (carbon dioxide) of cellular respiration is exchanged by the LUNGS.
The cellular structure performs the same task for a cell
B. mitochondrion
Mitochondria:The Lungs of multicellular organisms, as defined on this question, is a breathing organ this is concerned with the INTAKE of oxygen wanted for cell breathing and EXPULSION of carbon dioxide out of the body, a manner referred to as GAS EXCHANGE. This gaseous change feature of lungs is finished for the manner of breathing that is finished on the cell degree via way of means of MITOCHONDRION. Mitochondrion is an organelle in eukaryotic cells related to the cell breathing (launch of energy). The gaseous reactants (oxygen) and products (carbon dioxide) of cell breathing is exchanged via way of means of the LUNGS.

Explain the difference between food-chain and ecosystem.Explain the difference between food-chain and ecosystem.
Answers
Answer:
A food chain shows the transfer of energy through a single chain of animals. For example, energy comes from the sun, a producer uses energy from the sun as food, a secondary consumer eats the primary consumer, a tertiary consumer eats the secondary consumer, and so on. An ecosystem contains many intertwining and interlocking food chains. Ecosystems contain both abiotic and biotic factors.
• Food chain is a chain of species and organisms where energy transferred from one trophic level to another.
• Level of energy transferred decreases as one move from one level to another.
• It is single directional transfer or flow of energy.
• All living species need energy for growth and survival
• Plants are consider producer since they make their food using sunlight, soil and other elements.
• Animals are consider consumers since they gain energy from eating other plants and animals.
Generally we have four Trophic level:
• Producers
• Primary consumers
• Secondary consumers
• Top consumers
Example:
• Vegetation→ Grasshoppers → Frog→ Snake → Eagle
• Plant → Frog → Snake → Peacock
• Interaction between living and non living component i.e. biotic and abiotic factor makes up an ecosystem.
• Biotic factor consists of plants, animals and decomposer.
• Abiotic factor consists of mountains, light, soil, air and water.
• Example: Forest is an terrestrial ecosystem it consist of plants and animal. A lake is an example of aquatic ecosystem aquatic plants and animals.

Answer:
D) Genetic engineering
Explanation:
It makes the DNA living organisms
Through the process of genetic engineering scientists can artificially change the DNA code of the organisms. Thus, the correct option is D.
What is Genetic engineering?Genetic engineering is also called as the genetic modification or genetic manipulation. Genetic engineering is the modification and manipulation of an organism's genes through the use of technology. It is a set of technologies which are used to change the genetic makeup of the cells, including the transfer of genes within the cells and across the species boundaries to produce improved or novel organisms.
Different types of genetic engineering include DNA extraction, through which DNA is extracted from an organism known to have the desired trait and sequence. Gene cloning includes the gene of interest which is located and copied in the DNA. Gene modification is the modification of the gene to express in a desired way through altering and replacing the gene regions.
Therefore, the correct option is D.
