Importance of the water cycle
Answer:
because it ensure the availability of water for all livings, 95% of our world is covered with water but most of them are either forzen or under ground and also purifies water which can be ready for reuse.
One hypothesis that proposes to explain senescence notes that cells that divide throughout the life course have shortened DNA sequences at the end of the chromosomes. This is referred to as the ________ hypothesis.
Answer:
Telomere
Explanation:
The correct answer would be telomere hypothesis.
The telomere hypothesis is the main hypothesis that links aging, otherwise known as senescence, to the shortening of telomeres. Telomeres are short DNA nucleotides found at the end of each chromosome of humans.
The hypothesis postulates that loss of telomeres in the vegetative cells of the body is primarily responsible for cell aging or senescence.
Hence, the correct answer would be the telomere hypothesis.

A food chain consists of several organisms. Suppose one of the organisms in the chain disappears. What effect can this have on the other organisms in the food chain?
Answer:
All organisms in that food chain would starve until they die unless they could possibly move to a different habitat.
Explanation:
And because of all those organisms not being able to properly feed due to an organism missing in the food chain of that habitat, the population of those animals would decrease as well.

Raghavan has two identical plants. He plants one outside in the ground. The other is growing indoors without direct light. Raghavan predicts the weight of the carbon dioxide and water taken in by the plant and the oxygen given off by the plant.
Raghavan notices that a rabbit family has been eating the outdoor plant and that small insects are eating the indoor plant. He sees a fox hunting rabbit, but nothing is eating the insects.
The diagrams show Raghavan’s plants. Raghavan predicted the weight of carbon dioxide and water taken in by the plant. He predicted the weight of oxygen given off by the plant. What should he predict for the weight of the sugar the plant made?

The fibrous protein that gives skin its flexibility and helps skin regain its shape after being expanded is:
Answer:
Elastin
Explanation:
The elastin is defined as an extracellular matrix protein which lends to the elasticity and also resilience to the tissues such as the lungs, skin, arteries, tendons, and the ligaments.
Elastin synthesized from precursor molecule named tropoelastin.
Elastin is the fibrous protein which gives the skin its flexibility and also helps the skin regain its shape.

punto de vista sobre la ley de mendel
Answer:
Las leyes de Mendel son leyes que describen la herencia de rasgos hereditarios. Las leyes forman la base de la genética clásica. Asumen que cada individuo posee dos alelos para el mismo rasgo y los recibe al azar de los cuatro alelos diferentes de los padres. El fenotipo (apariencia física) del individuo depende de cuál de los dos alelos es dominante y cuál es recesivo. Dado que los individuos pueden transmitir ambos alelos a su descendencia, la descendencia incluye tanto individuos con fenotipo dominante como recesivo.

Which greenhouse gas has an average lifetime in the atmosphere of a few weeks to thousands of years and is the largest contributor to climate change?
Answer:
Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20th century.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents.
Explanation:
Why does it matter?
As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes, which have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations.

One student made the incomplete diagram shown below to represent the relationship between magma igneous rocks and metamorphic rocks.
Which of these is the correct next step to complete the diagram?
A. Put an arrow labeled cools and crystallizes pointing from igneous rocks to metamorphic rocks
B. Put an arrow labeled cools and crystallizes pointing for metamorphic rocks to igneous rocks
C. Put an arrow labeled heat and pressure points in from igneous rocks to metamorphic rocks
D. Put an arrow labeled heat and pressure pointing from metamorphic rocks to igneous rocks
Answer:
C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks
Explanation:
Metamorphic rocks are changed rocks that are formed from pre-existing rocks that were once sedimentary or igneous rocks. Heat and pressure majorly act on igneous rock, which over time change these rocks into a different rock entirely, known as metamorphic rocks.
Therefore, the next step to complete the diagram will be:
"C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks."

A population of rabbits has individuals with fur coloring that ranges from white to brown. The population lives in a temperate deciduous forest where the summers are mild and average about 50°F. The winters are often below freezing.
If warmer temperatures last longer into the fall and the average temperature in the winter is getting warmer, what do you expect to happen to the population?
The percentage of the population with brown fur will decrease.
The percentage of the population with white fur will decrease.
The population will increase in size, but the color percentages will remain unchanged.
The population will decrease in size, but the color percentages will remain unchanged.
Answer:
The best option for this problem would be the second option: "The percentage of the population with white fur will decrease"
Explanation:
Think about animals up in the north. Most of them are white because it helps them blend in the snow. And so an increase in average temperatures would mean less snow time. This would mean that the white rabbits will be more vulnerable to attacks for a longer time period of the year compared to previous years with a short time period of being vulnerable.
