How does lack of water conservation affect the hydrological cycle
Answers
Human activity such as the burning of fossil fuels has an effect on the overall increase of the Earth's temperature. Raising the Earth's temperature means that there is an increase of evaporation, melting of land and sea ice, and impacts on other processes of the water cycle that adversely affect the climate on Earth.

under the biological species concept, what criterion is used to assign populations of organisms to the same biological species?
Answers
Answer: According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring. Speciation is the process by which new species form
3) When two atoms bond chemically it is because of the interaction between
A) the nuclei of each atom.
B) the protons in each atoms.
C) all electrons in the atoms.
D) the valence electrons in each atom
Answers
Answer:
C - All electrons in the atoms
Explanation:
It depends on the bonding for an explanation.
If one atom is a metal and one is a non metal it will be ionic. This is because one atom transfers its electron to the other atom giving them both a charge. They will then be bonded due to opposite forces of attraction.
If both atoms are non metals it will be covalent. Electrons pair together in the center of two atoms that have merged together and they share their electrons.

soil is the largest terrestrial pool of carbon , containing about 2,200 gigatons. the primary reason that soil is such a large pool of carbon is which of its characteristic?
A) formation from weathering of rocks
B) organic content, including microbes
C) pore spaces allowing the flow of water
D high surface area increasing oxidation
Answers
The characteristic of soil that makes it the largest pool of carbon is its organic content, including microbes.
Soil is defined as the outermost portion of the earth's crust on which plants grow. The soil is the part of the earth that supports plant growth because it is rich in nutrients and organic matter.
Plants and animals die and decompose. The carbon content of these organisms are thereby returned to the soil. Also, many microbes are found in soil. Therefore, the characteristic of soil that makes it the largest pool of carbon is its organic content, including microbes.

A female mouse is trying to decide if she will leave her natal nest to reproduce alone. If she leaves, she will be able to produce 45 offspring whereas she would only have 7 reproductive units if she stayed. But if she stays, she will help her mother produce 175 offspring vs the 85 she could produce without her. Should she stay

Answer:
142 is the answer whe you add 45 7 and 85
A female mouse is trying to decide if she will leave her natal nest to reproduce alone. She will produce 142 offspring.
What is reproduction?
Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique.
In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism that reproduces asexually, and a brittle star can reproduce in either way.
Reproduction is the process by which new organisms (offsprings) are produced from organisms of the same kind.
Therefore, A female mouse is trying to decide if she will leave her natal nest to reproduce alone. She will produce 142 offspring.

what are the similarities between this activity and actual mitosis
Answers
The DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.
What is mitosis?Mitosis is defined as the cell-division process in which the chromosomes multiply and are equally distributed between the two daughter cells. Prophase, Prometaphase, Metaphase, Anaphase, and Telophase are the five stages that make up mitosis. Meiosis is defined as a process by which a single cell undergoes two divisions, resulting in four cells with half the original genetic material.
Cell division occurs during meiosis as well as mitosis. The M-phase of the cell cycle is where both processes take place. The prophase, metaphase, anaphase, and telophase stages are typical for both cycles. DNA synthesis occurs during both cycles. A common goal of meiosis and mitosis is the division of the nucleus and its DNA into two daughter cells.
Thus, the DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.

If annual rainfall decreases and causes ponds in this habitat to become shallower, after many generations, how might the traits of these water lilies change?.
Answers
The water lilies might adjust to requiring less water overall, even for drinking.
What is adaptation?According to the idea of evolution, adaptation is the biological mechanism that allows organisms to adjust to new settings or to changes in the environment in which they are already living.
It is absolutely necessary for living things to be able to adapt in order to stay alive. Animals who are unable to adjust to the shifting conditions of their habitat ultimately perish. These alterations are the product of shifts in genetic make-up. The mutant genes are passed down from the animals that make it through the ordeal to the next generation.
Therefore, the water lilies might adjust to requiring less water overall, even for drinking.
