Answer: Osmosis occurs when _solvent molecules__ goes from ____lower_____ to ___higher solute concentration______. When the onion and elodea cells were put in salt water the ____water molecules_________ left the cell because their was a ____higher salt concentration________amount outside.
Explanation: Osmosis is simply defined as the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration usually through a semi-permeable membrane. Water continues to move out the cell until both solutions in the intra- and extracellular membrane becomes isotonic.

Even though mitosis and meiosis produce cells for different purposes, there are similarities between the two processes. Which statement most accurately states how the two types of cell division are alike?
Group of answer choices
The daughter cells produced by both processes are haploid.
Homologous chromosomes cross over during the first prophase stage in both processes.
DNA replicates before mitotic prophase and prophase II.
Sister chromatids separate during anaphase II and mitotic anaphase.
Answer:
The daughter cells produced by both processes are haploid
Explanation:
The statement 'sister chromatids separate during anaphase II and mitotic anaphase' most accurately states how the two types of cell division are alike.
The sister chromatids are identical copies that form during the DNA replication of a chromosome.Sister chromatids separate during Anaphase in mitosis to form two daughter cells.Conversely, during meiosis, homologous chromosomes separate during Anaphase I, while sister chromatids separate during Anaphase II to form four haploid cells.In conclusion, the statement 'sister chromatids separate during anaphase II and mitotic anaphase' most accurately states how the two types of cell division are alike.

How do natural pollination and artificial pollination differ
Answer:
Natural pollinators, like bees, pollinate flowers randomly, essentially mixing up their genomes and increasing genetic diversity. This leads to different types of future plants. However, artificial pollination is so labor intensive, it's hard to replicate the same variety in pollination.Aug 8, 2017
Explanation:
Artificial pollination is the type of pollination carried out by humans. It is a mechanical technique used to pollinate plants when natural pollination is insufficient or undesirable. It does not require the help of insects or weather.
Natural pollination consists of the transfer of pollen between the male and female organs of the flowers, without human intervention. In other words, pollen is transferred from the stamens to the stigma of the flowers, where it fertilises the ovules, making seed and fruit production possible.

What is genetic diversity?Genetic diversity refers to the variation in genes and inherited traits that exists within and among populations of organisms. This variation arises due to a number of factors, including mutations, genetic recombination, and genetic drift. Genetic diversity is an important aspect of biological diversity, as it can allow populations to adapt to changing environmental conditions and may enhance their overall fitness and survival.
Genetic diversity can occur at different levels, ranging from variation within individuals (such as somatic mutations) to variation among populations of the same or different species. It is important to maintain genetic diversity within populations and across species in order to preserve the overall health and viability of ecosystems.

What is a benefit to utilizing fusion reactions instead of fission reactions?
A)Fusion reactions do not require any kind of radiation shielding to prevent exposure.
B)Fusion reactions do not produce harmful radiation and transuranium nuclides.
C)Fusion reactions can proceed in any temperature range.
D)Fusion reactions are easier to control and regulate.
Answer:
B)Fusion reactions do not produce harmful radiation and transuranium nuclides.
Explanation:
___________
The benefit of utilizing fusion reactions instead of fission reactions is that the fusion reaction does not produce harmful radiation and transuranium nuclides. Thus, the correct option for this question is B.
What is meant by Fusion?Fusion may be defined as a type of process that significantly involves the combination of two or more atoms or molecules in order to form one larger molecule. This type of reaction normally occurred in nature as compared to fission.
The process of fission involves the disintegration of numerous smaller molecules or atoms from a larger one. This creates a lot of long-lived radioactive substances in nature that are harmful to live organisms. These types of reactions are not favored by nature.
Therefore, fusion reactions do not produce harmful radiation and transuranium nuclides are the benefit of utilizing fusion reactions instead of fission reactions. Thus, the correct option for this question is B.

How long can water remain stored in a confined aquifer?
millennia
a few days
more than a million years
several years
It will take several years to store water in a confined aquifer.
What is confined aquifer?An aquifer that is enclosed and contains a lot of water is called a confined aquifer. The aquifer is under pressure because of layers of impermeable material that are both above and below it.
As a result, when the aquifer is pierced by a well, the water will rise above the aquifer's surface.
An aquifer with a water table, also known as an unconfined aquifer, has its upper water surface at atmospheric pressure, allowing it to rise and fall.
Due to their typical proximity to the Earth's surface, water table aquifers are affected by drought conditions earlier than restricted aquifers.
Therefore, It will take several years to store water in a confined aquifer.

The primary reason that osteoporosis accelerates after menopause in women is: * 2 points A. Increased osteoblast activity. B. Reduced levels of vitamin C. C. Diminished osteoclast activity. D. Reduced levels of circulating estrogens.
Answer:
The correct answer is D. Reduced levels of circulating estrogens.
Explanation:
Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.
