Human beings are omnivores.
The term "omnivores" refers to generalized feeding i.e., they can consume both plants and meat. They have specialized adaptations for gathering, eating, and processing food that contains both plant protein and animal protein. McArdle goes on to say that omnivores are primarily "opportunistic" feeders that take advantage of food opportunities in order to survive. They exhibit more universal physiological and anatomical characteristics. One such feature is the human dentition (set of teeth). It proves that the human diet is by nature omnivorous and not herbivorous given the presence of canine teeth for tearing flesh and molars for grinding and chewing. Our digestive system is shorter than that of a herbivore and longer than that of a carnivorous animal. A characteristic of omnivores is this. Vegetation requires a longer digestive system as that of herbivores to be fully digest than plant based diet. Meat is however, easily broken down. Nevertheless, consuming animal protein is not necessary for humans. It's up to you what you do.Hence, human dentition and length of the digestive tract are examples that suggest that humans are adapted to have an omnivorous diet.

During a six-month period, 239 cases of pneumonia occurred in a town of 300 people as a result of Coxiella burnettii infections. Before the outbreak, 2000 sheep were kept 30 miles northwest of the town, 95% of sheep tested were positive for C. burnetii.

The outbreak of pneumonia in the town of 300 people during a six-month period was likely caused by the Coxiella burnetii infection present in the 2000 sheep kept 30 miles northwest of the town. The presence of the infection was confirmed by 95% of the sheep tested being positive for C. burnetii.
The wind blowing from the northwest and the lack of rainfall compared with the previous three years, 0.5 cm compared to 7 to 10 cm, created an ideal environment for the spread of the infection. The reservoir of infection for this outbreak was likely animals, specifically the sheep. C. burnetii is an obligate intracellular bacterium that primarily affects animals, though it can also cause disease in humans.
The bacteria is spread through host animals via the fecal-oral route, as well as through infected urine, milk, and other bodily secretions. The bacteria can also be spread through the air, a process known as aerosolization, which can occur when infected animals release the bacteria in aerosolized forms such as coughing or sneezing.
The lack of rainfall in the area could have contributed to the spread of the infection, as the dry air could have allowed the aerosolized particles to travel further distances. Additionally, the wind blowing from the northwest could have also contributed to the spread of the infection, as it could have carried the aerosolized particles from the sheep to the town of 300 people.

Five strands of mRNA are depicted here, numbered 1-5. The mRNA sequence labeled number 1 indicates the codons that result from the transcription of the original, unmutated DNA. Identify the statements below that accurately describe the impacts of the mutations shown based on the illustrations. Select the three (3) answer choices that apply.
The statements that accurately describe the impacts of the mutations shown based on the illustrations are: Mutation 1 is a silent mutation, Mutation 2 results in a frameshift mutation and Mutation 4 results in a premature stop codon.
Options A, B & D are correct.
A silent mutation is a change in the DNA sequence that does not change the amino acid sequence of the resulting protein. In this case, mutation 1 is a substitution of a single nucleotide, but it still results in the same amino acid (leucine), so it is a silent mutation. Therefore, statement A is true.
A frameshift mutation is a type of mutation that results in the alteration of the reading frame of the codons in the mRNA sequence, which can lead to a completely different amino acid sequence downstream from the mutation site. In this case, mutation 2 is an insertion of a single nucleotide, which causes a frameshift mutation that changes the amino acid sequence downstream from the mutation site. Therefore, statement B is true.
A missense mutation is a change in the DNA sequence that results in a different amino acid being incorporated into the protein. In this case, mutation 3 is a substitution of a single nucleotide that changes the amino acid from leucine to proline. Therefore, statement C is true.
A premature stop codon is a type of mutation that results in the truncation of the protein sequence, usually leading to a non-functional protein. In this case, mutation 4 is an insertion of a single nucleotide that creates a premature stop codon, resulting in a truncated protein. Therefore, statement D is true.
Therefore, the correct answer choices are A, B, and D.

Name four divisona of seedless vascular plants and give examples
The four divisions of seedless vascular plants are; Lycophyta, Pteridophyta, Psilotophyta, and Equisetophyta.
Lycophyta; This division includes clubmosses, spikemosses, and quillworts. They have small leaves, are typically found in moist habitats, and have a primitive vascular system. For example; Selaginella species, Lycopodium species.
Pteridophyta; This division includes ferns, horsetails, and whisk ferns. They have larger leaves than lycophytes, more advanced vascular systems, and are found in a wide range of habitats. For example; Ferns (e.g., Adiantum, Pteris), Horsetails (e.g., Equisetum), Whisk ferns (e.g., Psilotum).
Psilotophyta; This division includes whisk ferns, which are very simple plants with no true roots, leaves, or stems. They are found in tropical and subtropical regions. For example; Psilotum species.
Equisetophyta; This division includes horsetails, also known as scouring rushes. They are found in wet habitats and have jointed stems, which are hollow and filled with silica. For example; Equisetum species

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.
What is the difference between weathering erosion and deposition?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’.
How can the complete rock cycle be described?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.

Natural vs. Man-Made: A dragonfly is a living creature, specifically an insect, belonging to the animal kingdom. On the other hand, a helicopter is a man-made machine, classified as an aircraft.
Method of Flight: Dragonflies fly using wings attached to their bodies, relying on their own muscle power. They have the ability to hover, glide, and change direction quickly. Helicopters, however, achieve flight through the rotation of their rotor blades, powered by engines. They can hover in mid-air, move vertically, and travel in any desired direction.
Size and Scale: Dragonflies are relatively small insects, typically measuring a few inches in length. Helicopters, in contrast, are much larger and come in various sizes, ranging from small personal helicopters to large commercial or military ones capable of carrying significant payloads.
