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.

Answer:

during cell division (meiosis)

Explanation:

During meiosis, DNA double-strand breaks (DSBs) between homologous chromosomes are induced and, after the exchange of DNA pieces, breaks are jointed by specific DNA-repair enzymes (such as DNA glycosylases). DSBs can be repaired by two different mechanisms: non-homologous end-joining (NHEJ) and homologous recombination (HR), which have different functional consequences. These mechanisms of recombination have potential for increasing the genetic variation since the resulting gametes will contain a different set of chromosome fragments.

An air mass that formed over the North Pole would differ from an air mass that formed over a warm ocean in several ways.

Air masses are large bodies of air with similar characteristics that form over a specific region of the Earth's surface and can travel long distances before encountering a different air mass that alters its characteristics. The characteristics of an air mass depend on the region over which it forms.

The air mass that forms over the North Pole would be cold and dry due to the absence of sunlight and the Arctic's high latitudes. Arctic air masses are characterized by a high pressure system that circulates air clockwise. This rotation traps cold air over the region and prevents it from mixing with the surrounding air masses.

The air mass that forms over a warm ocean would be warm and moist. The ocean surface warms the air above it, and the air acquires moisture through evaporation. The warm air then rises, causing low-pressure areas over the ocean and pulling in moisture-laden air from surrounding regions. This moist air mass travels over land, and its temperature decreases, causing it to lose its moisture content and form precipitation.

The moisture content in this air mass would be high, causing it to be humid. Air masses interact with each other and cause changes in weather patterns and climate. They also play a vital role in the Earth's energy balance and regulate temperature and precipitation patterns.

Environmental Factors Interact with Genes

Environmental factors often influence traits independently of genes. But not always. Sometimes the environment changes a gene—either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.

Answer: A) a process of change in a population through time

Explanation:

Answer:

A

Explanation:

Evolution is a process of change in a population through time

Answer:

This is an example of directional selection.

Explanation:

Directional selection is a type of positive selection where the evolutionary fitness of one genotype is higher compared to the other ones, thereby favoring the selection of one particular phenotype and shifting allele frequencies towards the selected genotype. In a biological context, the directional selection increases the chances for surviving and for reproducing in those organisms that have the alleles favored by this type of selection. Thus, the directional selection produces the loss of genetic variability and leads to the fixation of the dominant alleles.

Photosynthesis and cellular respiration are two close related and complementary processes. Photosynthesis produces organic molecules and releases oxygen, which are used during cellular respiration to produce water, ATP, and CO₂.

Photosynthesis is a process plant cells go through when absorbing sunlight.

During photosynthesis, light energy and inorganic compounds are used to produce organic compounds -glucose- and release oxygen.

It occurs in chloroplasts and involves two stages: light-dependent and light-independent reactions.

• During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions. It occurs in the thylakoid membrane in the electron transporter chain.

• The light-independent reaction occurs in the Calvin cycle in the stroma. During this stage, carbon from CO2 is fixated, and sugar molecules are synthesized

Cellular respiration is the process through which cells use organic compounds to produce energy.

Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

1. Occurs in the presence of free oxygen.

2. Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.

3. Respiration occurs in the mitochondria.

4. Takes place in two steps or stages: Krebs cycle and electron transporter chain.

5. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.

1. Occurs in the absence of free oxygen

2. Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.

3. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.

4. Lactic fermentation produces lactic acid and 2 ATP

5. Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂

6. The whole anaerobic process occurs outside the mitochondria.

Photosynthesis is complementary to cellular respiration.

Answer:

n order to create a Punnett square, we need to list the possible gametes (sex cells) that each parent can contribute to their offspring. Since Michael and Danielle both have the Bb genotype, they can each contribute a B or a b allele to their offspring.

Possible gametes for Michael: B or b

Possible gametes for Danielle: B or b

Using these gametes, we can create a Punnett square to show the possible genotypes of their offspring:

       B      b

B BB Bb

b Bb bb

From the Punnett square, we can see that there are four possible combinations of alleles for their offspring: BB, Bb, Bb, and bb.

BB: This offspring would have two dominant B alleles, resulting in dark brown skin.

Bb: This offspring would have one dominant B allele and one recessive b allele, resulting in tan skin.

Bb: This offspring would have one dominant B allele and one recessive b allele, resulting in tan skin.

bb: This offspring would have two recessive b alleles, resulting in light skin.

Therefore, it is possible for Michael and Danielle to have two babies with different skin colors, one with dark brown skin and the other with tan skin, due to the combination of their different alleles in their offspring.
