Answer:
Water collection for domestic use can be traced back to 560 BC when rainwater harvesting was practised in the Axumite Kingdom. In those days, rainwater was collected and stored in ponds for agriculture and water supply purposes. Evidence for this is in documented literature and may be observed in visible remains of ponds (Seyoum, n.d.). The history of modern piped water supply in Ethiopia began in 1924 when a piped supply was established from the Kebena River to the patriarch’s compound and Menelik Hospital in Addis Ababa, using an 80-mm pipe. Until the inauguration of the Gefersa Dam in 1951 the town of Addis Ababa was supplied from wells and springs (AAWSA, 2011).

Two snapdragon plants are crossed. One plant produces red flowers and the other plant produces white flowers. The cross between these two plants produces snapdragon plants with pink flowers. Which statement explains why the offspring have pink flowers? *
A. The offspring have two copies of the allele that codes for pink.
B. The offspring have one allele that codes for red and one allele that codes for white.
C. The flower color is determined by the dominant parent.
D. The flower color is determined by environmental conditions.
Answer:
The answer in B) The offspring have one allele that codes for red and one allele that codes for white.
Explanation:
Let's say that the red flower has Bb, and the white flower has bb. In a punnet square you'd get 50% being Bb and another 50% being bb. The allele bb would be pink.

A rolling ball travels 7.3m in 3.7s. What was the velocity of the ball?
Answer:
Velocity of rolling ball = 1.97 m/s (Approx.)
Explanation:
Given:
Distance travel by rolling ball = 7.3 meter
Time taken by rolling ball = 3.7 seconds
Find:
Velocity of rolling ball
Computation:
Velocity = Distance / Time
Velocity of rolling ball = Distance travel by rolling ball / Time taken by rolling ball
Velocity of rolling ball = 7.3 / .37
Velocity of rolling ball = 1.9729
Velocity of rolling ball = 1.97 m/s (Approx.)

Compared to the endocrine system, the nervous system has afaster response, but the signal does not last as long.slower response, and a signal that does not last as long.faster response with a longer-lasting signal.slower response with a longer-lasting signal.
Answer:
Has a faster response, but the signal does not last as long.
Explanation:
The nervous system uses action potentials to transmit signals. Action potentials have a short duration and travel fast through neurons to inform in a fast way about different stimuli and allow rapid answers. On the other hand, the endocrine system uses chemical molecules to transmit their signals. As they travel through blood or together with other molecules, their signal is not transmitted as fast as in the nervous system. However, when they reach their destination and interact with the proper molecules, they start a series of changes that have a lasting effect in contrast with the nervous system.

At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the ______________ layers and a second runs through the _____________ layers.
At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the parvocellular layers and a second runs through the magnocellular layers.
What are parvocellular and magnocellular layers?Parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus.
Moreover, magnocellular cells make up the magnocellular layers of the lateral geniculate nucleus. They are relatively large cells that display specialization in detecting aspects of movement, such as the location, speed, and direction of a moving object.
Therefore, magnocellular (M) and parvocellular (P) neuronal pathways that originate in the retina and project to separate M- and P-dedicated layers of the lateral geniculate nucleus (LGN) situated in the thalamus.

what is the primary functional difference between mitotic anaphase and meiotic anaphase 2?
Thrombocytopenia is characterized by an insufficient number of ____________ due to low production in the bone marrow or ____________ breakdown outside the bone marrow. Blood flow to the ____________ can stop completely and heart attack or stroke can result from untreated ____________ . An inherited clotting disorder with many forms, generally called ____________ , causes a deficiency in clotting factor. In all forms of this disorder, even the slightest bump causes ____________ in the joints.
Answer:
The correct words are - platelets, increased, tissue, thromboembolism, hemophilia, and bleeding.
Explanation:
Thrombocytopenia is a condition in which the number of platelets decreases significantly in the blood due to less production from the bone marrow or higher or increased breaking down of the platelets.
If the flow of the blood stops completely in between the heart and muscles and can lead to stroke in an individual if thromboembolism is not treated. Hemophilia is a blood condition that is a genetic disorder and inherits from the parents. In which blood does not clots and slightest bumps can lead to bleeding.

Asexual reproduction means that the organism comes from a single genetically identical.
What do you mean by asexual reproduction?A mode of reproduction known as asexual reproduction occurs when only one parent reproduces offspring. In abiogenetic proliferation, the offsprings created are precise duplicates of their folks.
The parent cell divides into two or more separate cells during asexual reproduction. Unicellular organic entities show various examples of cell division as indicated by their cell structure. Asexual reproduction is a form of reproduction that does not involve changing the number of chromosomes or fusion of gametes.
The various sorts of agamic multiplication are parallel splitting, sprouting, vegetative spread, spore arrangement (sporogenesis), fracture, parthenogenesis, and apomixis.

Answer:
The correct answer is -
1. Blending - C
2. Straining - D
3. Detergents - B
4. Meat tenderizer (protein enzymes) - E
5. Alcohol - A
Explanation:
To extract protein from various parts of the organisms there is a scientific process that helps in successfully extract it. Organisms such as plants have a rigid cell wall that is required to be broken in order to follow the scientific process of extracting DNA and protein.
Blending use to break the cell wall of the plants such as pea cells. After breaking the cell wall one needs to dissolve the cell membrane made up of lipids with the help of soap or detergents. After the dissolving cell membrane, there is a chance to DNA gets damaged by various chemicals, therefore, alcohol is used to allow DNA to form clumps or precipitate.
Straining is used to separate the cell organelle, dissolved cell membrane from DNA and protein. Papain is a meat tenderizer and a protein enzyme that cuts or breaks the protein.

What are the benefits of using recycled vegetable oil for fuel?
Answer:
One of the biggest advantages of using vegetable oil as a fuel is that unlike petrol, it is a renewable source of energy. It is abundantly available, and helps in recycling of waste products. The conversion kits which allow vegetable oil to run the engine are easily available.
Vegetable oil can be used as fuel in both diesel cars and heating oil burners. Reclaimed vegetable oil that is used in food service industries could be used to reduce the amount of fossil fuels that are being used by humans. When handled properly, it can help contribute to a cleaner and safer environment.

Answer:
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others.
