Answer: Scientists say that energy can neither be created nor destroyed, so therefore it is impossible for there to be an energy crisis.
Explanation:
I'm pretty sure I'm right
Answer:
There is a problem because if energy is created as machines worked everything would speed up until it breaks, and if energy was destroyed as machines worked everything would eventually slow down and stop. So in both cases the world would end, a whimper in one a bang in the other.

The ecosystem services are all the benefits provided by the ecosystem to human. Otion A) habitat for wildlife is not an ecosystem service.
What are the Ecosystem Services?
When talking about ecosystem services, we are referring to the goods and services offered by ecosystems to human populations
There are different types of ecosystemic services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing.
Among them, we can mention food, clear fresh-water, fertile soils, geotic materials, raw materials (used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, and others.
Regulation:Refers to ecological processes that improve life.
Among others, we might mention climate regulation, CO₂ absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil formation and fertility maintenance, nutrient cycling, waste recycling, pests/plagues control, etc.
Cultural:Refers to the benefits that are not material.
Ecosystems also provide a recreational place or area to spend time, learn. They are a spiritual/religious space, a source of inspiration. They are considered to be cultural patrimony and the source of scientific knowledge.

Diabetes mellitus is characterized by too much glucose buildup in the blood. In _________diabetes, this is because the target cells of the body become resistant to the effects of__________ insulin ; in later stages of this type of diabetes, the pancreas begins to fail as well. In type 2 diabetes, this is because there are a decreased number of_________ cells available to secrete insulin; this results in an insufficient amount of insulin to meet the demands of the body.
Answer:
The correct answer would be - Type 2, and beta respectively.
Explanation:
There are two types of two diabetes; type 1 and type 2. Type 2 daibetes is
When you have type 2 diabetes, your fat, liver, and muscle cells do not respond correctly to insulin. This is called insulin resistance. As a result, blood sugar does not get into these cells to be stored for energy.
Inorganic, crystalline substances found naturally within earth are known as
Answer:
Minerals.
Explanation:
Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
Hence, inorganic, crystalline substances found naturally within earth are known as minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
7. Explain how the equations for photosynthesis and cellular respiration compare.
Answer: In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water. C6H12O6 (glucose) + O2(oxygen) → CO2(Carbon Dioxide) + H2O(water) + ATP energy. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.
Explanation:
A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer, 75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant over brown (w). During the summer, the field where they live experiences a drought. The summer drought lasts for two years, through many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the drought?
Answer:
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
Explanation:
hope this helps!
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
What are the limiting factors of the rabbit population?Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.
Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.
Thus, the rabbit population will consist of 35% white rabbits and 65% brown rabbits.

Which of the following correctly explains the differences between artificial and natural selection?
Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.

Which pattern of inheritance does nose size follow?
complete dominance
codominance
incomplete dominance
sex-linked dominance
Answer:
incomplete dominance
Explanation:
This is because incomplete dorminance is a type of inheritance pattern in which a dorminant allele does not completely masked the effect of recessive allele. The recessive allele is expressed little and the dorminant. Example is the nose size. The allele for big nose and recessive allele for small nose are not completely dorminant.
Describe how knowing the column (group) number is a "cheat code" for determining the number and types of bonds that an element can form.
Answer and Explanation:
The columns of the periodic table are able to inform the number and type of connection that the elements can make. This is because the number of each column informs the number of electrons in the valence layer of the elements. The amount of electrons in the valence layer is what determines the amount and type of bond that the elements make. The elements in column 1, for example, have 1 electron in the valence layer and therefore will make 1 covalent bond. The elements of columns 15, as another example, have 5 electrons in the valence layer and will need to make 3 ionic or covalent bonds.
To describe how knowing the group number is a cheat code to determine the type of bonds that can be formed, we should first define periodic table
What is periodic tablePeriodic Table is a series of elements in which they are arranged in increasing order of their atomic number from left to right but the table also have groups (column) from up to downwards each group have atoms with same number of electrons in their last shell due to which they all have almost similar properties such as same magnetic properties ,same number of bonds formation, metallic character .
We can say that similarity in properties of members of same group is due to same number of valance electrons . For example group 14 i.e. Carbon Family ,all elements of this group will have 4 valance electrons and will form 4 bonds by sharing of their electrons.

What effect did the human population have on Easter Island? How did they change the island's natural cycling of matter and energy?
Answer:
The population history of the island remains highly controversial. In addition to internal conflict, the population crash has been attributed to “ecocide,” in which the Island's resources were exhausted by its inhabitants, reducing its ability to support human life.
Explanation:
Europeans was known to discovered Easter Island in 1722 and it's name was given by Captain Admiral Jacob Roggeveen.
The human population growth had a negative effect on the Easter Island.
The ecocide hypothesis is the one explanation to how the human population increased exponentially since its colonization and as such
Human populations did over increased the carrying capacity of the Island to support sustainable crops, and in consequence, the island was severely deforested.
The island's natural cycling of matter and energy also reduced or change and as such the people fought among themselves for scarce resources of the island. They had little food and were starving and they resorted to cannibalism.
The island was also plaque by blackbirding from 1862 to 1863.
