The graph shows a predator-prey relationship. As we can see, the number of snowshoe Hare increases when the amount of Lynx decreases.

When the number of Hares is big enough, the amount of Lynxes increases too because there is more food (Hares) available. After a period of time, the amount of Hares starts to decrease because they're being eaten, and in consequence the number of Lynxes starts to decrease too, starting a new cycle.

Answer: Non specific defence mechanism are the first lines of general defence that aids in preventing entry and minimising further passage of microbes and foreign materials into the body.

Explanation:

The non specific defence mechanisms protects us against any of enormous range of possible dangers using these methods:

--> defence at body surface

--> phagocytosis

--> natural antimicrobial substances

--> the inflammatory response and

--> immunological surveillance.

MUCUS is a slippery substance which covers the luminal surface of the Lungs. It provides defence at the body surfaces. Incase of any inhaled foreign material through the nose into the lungs, it's usually entrapped by the mucus. It is either coughed up or swallowed.

LYSOZYME: This is a protein with antibacterial properties present in granulocytes, tears and sweat. They are natural antimicrobial substances that destroys the cell walls of bacteria leading to its death.

ACIDIC Ph: The presence of acidic natural substances found in the stomach such as the gastric juice or hydrochloric acid, kills the majority of ingested microbes.

100% of the offspring will be homozygous round in this cross.

What is a homozygous?

A homozygous round is an organism that has two identical copies (alleles) of a particular gene that codes for the trait "round." This means the organism will always express the round trait, regardless of the environment or the presence of other alleles.

This is because the round pea plant that is heterozygous still carries two copies of the round gene. When it is crossed with a homozygous round pea plant, all of the offspring will have two copies of the round gene, making them homozygous round.

The total hydrogen bonds are holding the two strands together are 69 hydrogen bond.

DNA stands for deoxyribonucleic acid. It is defined as the molecules that has genetic material for development of organisms. DNA molecules are made up of two linked strands that  resemble a twisted ladder a shape called as a double helix.

As given there are 100 base pair of DNA molecules, in that 100 base pair there is 23% of cytosine base pair. So, to calculate the the amount o hydrogen atoms in the molecules we can just multiply 23 with 3 as it has 3 hydrogen bonds so the result is 46.

Thus, the total hydrogen bonds are holding the two strands together are 69 hydrogen bond.

C. Biotic and abiotic

Explanation:

Biotic factors, which are all living things, are found in all ecosystems. Abiotic factors, which are all non-living things, are found in all ecosystems.

Answer:

Answer is A

Explanation:

If you know about the energy pyramid, you would know that producers are at the bottom. Abiotic factors are factors that are non-living. Some examples are water, rocks, and the sun. Plants use energy from the sun to make food. Since the sun is an abiotic factor, it would make more sense that producers get their energy SOLELY FROM AN ABIOTIC FACTOR ( THE SUN ).

I am found only in the nucleus of eukaryotic cells (the exception is during mitosis, when the nucleus is temporarily disassembled) is DNA.

The DNA that is kept in the nucleus of eukaryotic cells is converted into RNA during transcription. the cell-based component that houses the genetic material needed for an organism to grow and function. This genetic material is then taken out of the nucleus and sent to the cytoplasm, where ribosomes utilise it to create protein. This knowledge is passed down from one generation to the next thanks to DNA molecules.

In prokaryotes, the DNA (chromosome) is not contained in a membrane-bound nucleus but rather is in direct contact with the cellular cytoplasm. In eukaryotes, however, the nuclear membrane divides the chromosomes from the rest of the cell because their DNA is organized into compact chromosomes (also called a nuclear envelope).

Lymph nodes filter and cleanse lymph before it reaches the bloodstream.

Lymph nodes are small, bean-shaped structures located throughout the body that are part of the lymphatic system. The lymphatic system is a network of vessels and organs that work together to transport and filter lymph, a clear fluid that contains white blood cells, throughout the body.

Lymph nodes act as filters that remove impurities, such as bacteria, viruses, and abnormal cells, from the lymphatic fluid before it returns to the bloodstream. Lymphocytes, a type of white blood cell, are also found within the lymph nodes and play a crucial role in the body's immune response by identifying and destroying foreign substances.

Answer:

The two wind systems where pressure belts meet are called the "Polar Front" and the "Intertropical Convergence Zone (ITCZ)".

Explanation:

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.

None of the statements is true of nonmetallic metals.

Nonmetallic metals are not a recognized classification of materials. Metals are elements that have a characteristic luster, are good conductors of heat and electricity, and are generally malleable and ductile. Nonmetals, on the other hand, tend to be brittle, poor conductors of heat and electricity, and have a variety of physical properties.

It is possible that the term "nonmetallic metals" is a confusion or misnomer with the term "metallic minerals", which refers to naturally occurring inorganic compounds that contain metals in their composition. Metallic minerals are often mined for their metal content, and have many uses in industry, construction, and technology. Examples of metallic minerals include copper, iron, gold, silver, and aluminum.

Therefore, option a) is not true because metallic minerals are indeed mined for their metal content. Option b) is not true because nonmetallic metals are not a recognized classification. Option c) is not true because metallic minerals have value. Option d) is not true because nonmetallic metals do not exist.

Among the following observations that would support the hypothesis that Plethodon salamanders did indeed experience character displacement for body size is (b) In sympatric populations, smaller P. cinereus adults survive better and reproduce more.

Option b could provide support for the hypothesis due to the fact that interspecific competition between P. cinereus and P. hoffmani is always present. Furthermore, P. cinereus is more aggressive, and some studies show that they encroach the habitat of P. hoffmani. This is due to the fact that P. cinereus is small but aggressive and not at all submissive, and that they are exploitatively superior due to the fact that they eat small soft-bodied prey.
