The polarity of water molecules is crucial to the formation and stability of cell membranes. Without this polarity, water would not be able to form hydrogen bonds, interact with polar molecules, or form stable cell membranes .

Water molecules are composed of two hydrogen atoms and one oxygen atom, and they have a slight negative charge on one end and a slight positive charge on the other.

This arrangement is due to the unequal sharing of electrons between the atoms, with the oxygen atom having a stronger pull on the electrons than the hydrogen atoms. This phenomenon is called polarity, and it is crucial to the unique properties of water.

First, water molecules would not be able to form hydrogen bonds with each other, which are crucial for many of water's unique properties. Hydrogen bonds occur between the positive and negative ends of different water molecules and give water its high boiling point, high surface tension, and the ability to dissolve many substances.

Furthermore, the polarity of water molecules is crucial to the formation and stability of cell membranes. The hydrophilic, or water-loving, heads of phospholipids are attracted to the polar water molecules, while the hydrophobic, or water-fearing, tails face away from the water.

In summary, the polarity of water molecules is crucial to many of its unique properties and is essential to many biological processes. Without this polarity, water would not be able to form hydrogen bonds, interact with polar molecules, or form stable cell membranes.

Article states that "plants take up carbon dioxide from atmosphere and convert it into food."

1.This supports the law of conservation of matter, which states that matter cannot be created or destroyed, and can only be transformed from one form to another. In this case, carbon dioxide in atmosphere is transformed into organic matter in form of plant tissue.

2. According to the article, new research shows that plants are photosynthesizing 5% more in response to increased levels of CO2 in atmosphere.

3.The article states that 5% increase in photosynthetic rate translates to  additional 5 billion tons of carbon being removed from atmosphere each year.

4.Article suggests that increase in photosynthetic efficiency may be a result of plants having more CO2 available to them, which stimulates photosynthesis.

5.Laboratory procedure used to quantify photosynthetic efficiency involves measuring amount of chlorophyll fluorescence emitted by plant. This fluorescence provides a measure of amount of light energy absorbed by plant during photosynthesis.

6. Field procedure used to quantify photosynthetic efficiency involves measuring amount of carbon dioxide taken up by plant during photosynthesis. This is done by placing plant in sealed chamber and measuring change in carbon dioxide concentration over time.

7.The article suggests that potential "saturation" of carbon dioxide in the atmosphere could lead to a leveling off of increased photosynthetic rates observed in plants.

9.The potential "saturation" of carbon dioxide in atmosphere refers to point at which plants would no longer be able to increase photosynthetic rates in response to higher levels of atmospheric CO2. If ecological photosynthetic rates were to reach saturation, it would mean that plants would no longer be able to remove more carbon dioxide from atmosphere through photosynthesis.

Explanation:

I just took it.

During a solar radiation storm, radio navigation and GPS systems will be inaccurate. The correct option is b.

Solar radiation storms usually happen when large amounts of energetic particles, such as protons and electrons, are accelerated by processes taking place at or near the Sun.

When these processes occur, high-energy particles bombard the near-Earth satellite environment.

Although solar eruptions can harm satellites, power infrastructure, and radio communications, they don't really harm people.

Solar storms eject radiations that are dangerous to humans and can cause organ damage, among other things.

The Earth's atmosphere and magnetosphere, as well as the planet's magnetic field, shield us from elevated particles and radiations.

As a result, solar flares have little effect on humans and animals living on the Earth's surface.

Refraction, on the other hand, bends the waves as they go through one medium to another medium, or change their direction. The amount or degree of the bend would depend on the medium they go through. If the mediums are different, it would substantially change the wave's path. The reason for this is because the medium changes the speed of the waves that go through them, depending on the material they are made up of.

A classic example of this would be the straw in a glass of water.

Diffraction occurs when the waves go through an opening of the medium or barrier. If the opening is smaller than the wave that passes through it, it would spread out wider, coming out of the opening, but if it is bigger, then the spread would decrease.

In x-ray crystallography, they use this by letting x-rays pass through the spaces in between the crystals

The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

During DNA replication (S phase), the chromosomes are duplicated, resulting in 16 sister chromatids. During metaphase, the sister chromatids align along the equatorial plane of the cell. During anaphase, the sister chromatids separate and move towards opposite poles of the cell, ensuring that each new cell receives a complete set of 8 chromosomes.

During mitosis, the process by which cells divide, the division of chromosomes occurs in a way that maintains the correct number of chromosomes in each resulting cell. The scenario you mentioned, where one cell with 8 chromosomes divides to form two cells each with 8 chromosomes, is possible due to three key events and their associated cell cycle phases:

DNA Replication (S Phase): Before mitosis begins, the DNA in the cell undergoes replication during the S phase of the cell cycle. This means that each chromosome replicates, resulting in two identical copies called sister chromatids. So, in the initial cell with 8 chromosomes, during S phase, each chromosome is duplicated, resulting in a total of 16 chromatids.

Chromosome Alignment and Separation (Metaphase and Anaphase): During metaphase, the replicated chromosomes align along the equatorial plane of the cell. The sister chromatids are connected at a region called the centromere. In anaphase, the centromeres split, and the sister chromatids separate, becoming individual chromosomes. The spindle fibers pull the separated chromosomes towards opposite poles of the cell.

Cytokinesis: After the chromosomes have separated, cytokinesis occurs, where the cell membrane pinches inward, dividing the cytoplasm into two distinct cells. Each new cell receives a set of chromosomes, resulting in two daughter cells, each with the same number of chromosomes as the original cell (8 chromosomes each).

Overall, through the processes of DNA replication, chromosome alignment and separation, and cytokinesis, the division of chromosomes during mitosis ensures that the resulting daughter cells maintain the correct number of chromosomes.

One example that is not true according to Mendel's law and meiosis is the inheritance of multiple genes that are located very close to each other on the same chromosome.

Mendel's law of independent assortment states that different genes are inherited independently of each other during meiosis, which means that the distribution of alleles for one gene should not influence the distribution of alleles for another gene. This is true as long as the genes are located on different chromosomes or are located far apart from each other on the same chromosome.

However, if two genes are located very close to each other on the same chromosome, they are said to be in strong linkage disequilibrium. During meiosis, the two genes may be inherited together as a unit, and the frequency of certain allele combinations may deviate from the expected frequencies based on independent assortment. This violates Mendel's law of independent assortment.

Therefore, the inheritance of multiple genes that are located very close to each other on the same chromosome is not true according to Mendel's law and meiosis.

Answer:

1) Weathering, Erosion, Disposition

2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.

3) The four forces of erosion are water, wind, gravity, and glaciers.

4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.

--------------------------------------------------------------------------------------------------------

Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.

----------------------------------------------------------------------------------------------------------

Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.

--------------------------------------------------------------------------------------------------------

Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.

---------------------------------------------------------------------------------------------------------

Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering

----------------------------------------------------------------------------------------------------------

Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.

Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.

Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.

Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.

If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.

Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.

Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.
