Answer:
A river system is made up of a river and its tributaries.
What is a river system?
A river system is a term used to describe the broader networks of streams, lakes, and rivers that are tributaries and distributaries of a larger river. For instance, the Mississippi River system includes the Ohio, Red, and Missouri rivers, all of which drain into the Mississippi River. Due to its interconnectedness, the condition of one river may have an effect on the health of the other rivers in the same river system. A river system can also include other types of terrain, such as the wetlands and flood plains that are affected by a major river and its tributaries and distributaries. The majority of the time, rivers have a primary source, such as snowmelt from a mountain that cascades into a number of streams, which eventually merge to form a river that empties into a much bigger river. This is an illustration of a river network. River systems are ecosystems from an environmental perspective, and if even one component of the system is contaminated or destroyed, it may have a severe impact on things like water quality and the health of plants and animals. For instance, the effects of high pollution levels or prolonged drought near a river's source will be felt throughout the rivers and lands that make up the river system.
An example of this is the Amazon River in Brazil (South America).
Answer:
A river system is made up of a river and its tributaries.

N an experiment, suppose that the wings of fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on
a. inheritance of natural variations
b. inheritance of acquired characteristics
c. natural selection
d. survival of the fittest
Inheritance of acquired characteristics. Thus, option "B" is correct.
What is inheritance of acquired characteristics?For fifty generations wings of fruit flies were clipped. Hence they acquired this trait in their lifetime and not genetically. If acquired characteristics were capable of passing on to next generation, 50 generations would have been enough to inculcate this clipped wing trait in fruit flies. Despite it, the fifty-first generation did not have clipped wings.
Hence evolution can not occur without genetic variation. A character simply acquired in a lifetime does not create a difference in germ cells and hence is not enough to be passed on to next generation or cause evolution

Did the amount of water that condensed at the top of the terrarium change as plants sprouted and grew? described what you observed, using data from your experiment. why do you think this happened ?
The amount of water that condensed at the top of the terrarium change as plants sprouted and grew because water, oxygen and nutrients are very essential elements for growth.
The plant cells grow in size by cell enlargement which in turn requires water. Turgidity of cells helps in extension growth. Thus, plant growth and further development is intimately linked to the water status of the plant. Water also provides the medium for enzymatic activities needed for growth. Oxygen helps in releasing metabolic energy essential for growth activities. Nutrients (macro and micro essential elements) are required by plants for the synthesis of protoplasm and act as source of energy.
Thus as plant grows it needs more water to provide to it's larger plant body and which causes decrease in the amount of water that condensed at the top of the terrarium.

Answer:
Initiation Transcription or (promoter)
Explanation:
∙ Transcription is the process of RNA production from DNA.
∙ During transcription, RNA polymerase produces a copy of a gene from the DNA to mRNA.
∙ During transcription, the DNA location at which RNA polymerase interacts is termed a promoter.
∙ Transcription begins with attachment of sigma factor proteins to the RNA polymerase holoenzyme, therefore, allowing it to bind to promoter DNA.
∙ RNA polymerase forms a transcription bubble, which divides the two strands of the DNA helix.
∙ Then RNA polymerase proceeds towards the transcription start site for the process of transcription.
5. Draw conclusions: Natural selection is the process by which favorable traits tend to increase in frequency over time. How does this experiment illustrate natural selection
Natural selection is usually defined as the process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food of mates, will tend to survive and reproduce in greater number than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations. Charles Darwin and Alfred Wallace developed the theory of evolution by natural selection and jointly presented papers on the subject in 1858. It is based on the finding that some distinctions between people in a group can be passed down across generations. Darwinism, or Darwin's theory, is a theory of evolution created by Charles Darwin stating that all life forms arise, change and develop from a process of natural selection. Natural selection is the process of changes in evolution due to the survival of certain individuals in a species. It is one of the most important parts of the theory of evolution. Darwin's idea provided a straightforward yet persuasive explanation for the diversity of species on Earth. Because various locations have distinct circumstances and survival possibilities, natural selection selects the organisms that are best adapted to that particular environment.
Which factor is MOST likely to have contributed to the high fertility rate in Africa?
A-many Economic opportunities
B-poor access to medical care
C-high rate of education
D-Lack of access to food
Answer:
The answer is B. Poor access to medical care
Poor access to medical care is most likely to have contributed to the high fertility rate in Africa. Option B is correct.
Fertility rate is the average number of children that a woman will have in her lifetime. In Africa, the fertility rate is high, meaning that women on average have more children than in other parts of the world. There are many factors that contribute to high fertility rates, but one of the most important is poor access to medical care.
When women do not have access to contraception, they are more likely to become pregnant. They are also more likely to die in childbirth if they do not have access to medical care. In many parts of Africa, girls are married off at a young age. This means that they start having children at a young age, which can lead to higher fertility rates.
In some cultures, it is seen as desirable for women to have many children. This can also contribute to high fertility rates. In some parts of Africa, there are few economic opportunities for women. This can make it difficult for women to support themselves and their children, which can lead to higher fertility rates. Option B is correct.
