A. If he hadn't relied on adults or been resourceful, Salva Dut would never have survived in A Long Walk to Water. Relying on adults and being resourceful were the two factors that made it possible for Salva to survive. A Long Walk to Water by Linda Sue Park was a story of survival and success.
Salva had to leave his village because the war struck. He now must walk all day, every day to find safety. The environment challenges him by making him dehydrated and both mentally and physically hurt. “Uncle cautioned him to make the water in his gourd last as long as possible.
Explanation:
Both hexokinase IV and hexokinase I phosphorylate glucose at carbon-6. What properties of hexokinase IV make it important for maintaining stable blood sugar levels
I am going to explain the properties of hexokinase IV and it's properties that make it important for the maintainance of stable blood sugar level.
Hexokinase as well as Hexokinase IV all phosphorylate the glucose at C-6, Because Hexokinase IV has a low affinity with glucose and it is expressed in the liver,so it does have a way of maintaining blood sugar level.
When the blood glucose is low generally,it isn't saturated or working,but when the blood glucose gets high,it becomes transactivated and the activity of glucose 6 phosphatase results in low blood glucose.
Therefore,the most important activity of
Hexokinase IV is the regulation of blood glucose levels.

WHAT'S THE DIFFERENCE BETWEEN INCOMPLETE DOMWANCE AND CO-ODOMINANCE ? GIVE EXAMPLES OF THE BOTH INCOMPLETE AND
CO-ODOMINACE. USE THE PUNNET SQUARE TO SUPPORT YOUR ANSWER
Answer/Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other, resulting in an intermediate phenotype. Example could be in flower colour. F is the allele for red flowers, f is the allele for white flowers. Let's cross a red flower (FF) with a white flower (ff):
F F
f Ff Ff
f Ff Ff
100% of the offspring are Ff. F is in completely dominant to f, so all the offspring have an intermediate phenotype - all the flowers are pink.
Co-dominance is when neither allele is dominant and both alleles are expressed equally. An example is in human blood types. A and B alleles are both dominant to the O allele, but co-dominant to each other. Therefore, if an individual who is AO has children with an individual who is BO:
A O
B AB BO
O AO OO
The individual would either be blood type O (OO), blood type A (AO), blood type B (BO) or blood type AB (AB)

Based on their half-life values, which radioisotope would be best suited to determine the age of a woolly mammoth bone
Answer:
Wolly mammoths existed about five million years ago. Therefore, based on their half-life, the radioisotope which would be best suited to determine the age of a wooly mammoth bone is Uranium - 235 whose half-life is approximately 700 million years.
Explanation:
Uranium 235 is a variant or an isotope of Uranium. Isotopes are a derivative of a particular chemical element which are alike but different in the number of nucleons they contain.
In relation to age testing, the time taken for any specified property to decrease by half of its original value is called a half-life.
Thus the radioactivity of Uranium - 235 takes about 700 million years to fall to half it's original value.
Because of its half-life, Uranium - 235 is the best used when dating very old fossils.

Why do cells need to be able to control movement of substances across the plasma membrane?
Answer:
To move substances against a concentration or electrochemical gradient, the cell must use energy. Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements.

Explanation:
One of the most common sources of phosphate pollution that has led to eutrophication has resulted from the use of
Answer:
Phosphate fertilizers
Explanation:
One of the most common sources of phosphate pollution is run-offs from phosphate fertilizer from agricultural processes. Farmers deploy phosphate-containing fertilizers to soils in other to improve the overall fertility of the soil and the yield of crops.
Some of these fertilizers find their ways into nearby water bodies through washing up by erosion thereby raising the phosphate levels of these water causing eutrophication.
Other common sources of phosphate pollution include industrial and domestic run-off as well as detergents although phosphate-containing detergents are now becoming a thing of the past.
why is cytoplasm present in all cells?
Answer: Cytoplasm is present in all cells because it is the placeholder of the cell. It helps to fill in the cell and holds all the organelles in their place. If the cell did not have cytoplasm, the cell would be deflated and some certain materials would not have the ability to pass easily from one organelle to another. Hope this helps!

How might a reduction in species diversity affect the other three components of biodiversity?
Answer:
if the species diversity in an ecosystem or on the Earth gets reduced, it will affect the balance biodiversity and its other components. The three components of biodiversity are: ecosystem, species, and genetic diversity.
Biodiversity is defined as the variety of life forms existing in different ecosystems on planet Earth.
The three components of biodiversity are:
genetic diversity, species diversity, ecosystem diversity.If there is a reduction in the species diversity, there will be an imbalance in biodiversity, which is integrated, where each living being has an essential role in the maintenance and sustainability of the planet.
Biota reduction will therefore directly impact the ecosystem and will alter the correct flow of environmental balance.
It is possible to see through history, that many species of animals were extinct by human exploitation and this action cannot be reversed.
Therefore, it is essential to make each individual aware of the importance of developing sustainability for the preservation of nature and the quality of life of current and future generations.
