Skeletal muscles are _____ formed by skeletal muscle tissue, and the tissue is made up of skeletal muscle ______.
A.)cells; organs
B.)organs; cells
C.)cells; organ systems
D.)organ systems; cells
Final answer:
Skeletal muscles are organs made of skeletal muscle cells, which possess the unique feature of contractility, allowing for voluntary movement and locomotion; they also assist in regulating body temperature.
Explanation:
Skeletal muscles are organs formed by skeletal muscle tissue, and the tissue is made up of skeletal muscle cells. Skeletal muscle tissue is a type of muscle tissue that has the unique ability to contract, or become shorter, enabling the body to move. This tissue is composed of long and cylindrical cells known as myocytes, which are multinucleate (having multiple nuclei). These cells exhibit a striated appearance under a microscope, revealing a regular alignment of the contractile proteins actin and myosin that are responsible for muscle contraction.
Additionally, skeletal muscle tissue is connected to bones, sometimes to the skin, and controls voluntary movement and locomotion. It is called voluntary muscle because it can be controlled consciously. The importance of skeletal muscles extends beyond movement, as they also participate in thermal homeostasis through the generation of heat, especially noticeable when shivering occurs in response to cold temperatures.

In the drawing, why do the oxygen atoms look different from the hydrogen atoms?
In a drawing of a molecule, the oxygen atoms may look different from the hydrogen atoms due to the simplified drawing method and the difference in electronegativity.
Explanation:In a drawing of a molecule, such as water (H2O), the oxygen atoms may look different from the hydrogen atoms due to two main reasons:
First, organic chemists use a simplified drawing method called a skeletal structure, where hydrogen atoms attached to carbon are not drawn.Second, the difference in electronegativity between oxygen and hydrogen causes a partial negative charge near the oxygen atoms and a partial positive charge near the hydrogen atoms.These differences in representation help simplify the drawing and highlight the charge distribution within the water molecule.

Alcoholic fermentation
A. forms fewer ATP molecules than cellular respiration
B. uses oxygen and ATP molecules as reactants
C. occurs in the muscle cells of animals and humans
D. gives off carbon dioxide and NADH as products
Answer:
Option (A).
Explanation:
Alcoholic fermentation may be defined as the biological metabolism that converts the glucose and other sugars into the ATP and ethanol as by product.
The alcoholic fermentation yield less molecules than the aerobic respiration. Only 2 molecules are produced in the alcoholic fermentation whereas 32 molecules of ATP are produced in aerobic respiration. Carbon dioxide is also released in the alcoholic fermentation.
Thus, the correct answer is option (A).

To ensure reliable and valid results in investigating the unusual color of water in wells, students should analyze land surfaces, gather data on polluted wells, and conduct multiple water sample analyses.
Explanation:To ensure that the results of the investigation on the unusual color of water in wells are reliable and valid, the students should:
Conduct a thorough analysis of the land surfaces to identify potential sources of pollution, such as nearby factories or agricultural activities.Gather data on the locations of the polluted wells, including the distance from potential pollution sources and the depth of the wells.Take multiple water samples from the polluted wells and analyze them for various parameters, such as pH levels, presence of contaminants, and concentration of pollutants.Compare the data collected from the polluted wells with data from nearby clean wells to establish a baseline and determine the extent of contamination.Repeat the sampling and analysis process multiple times to ensure the consistency and accuracy of the results.Suggest why there are fewer shire horses today
Final answer:
The decline in the number of shire horses today can be attributed to the mechanization of farming, urbanization, and the preference for other horse breeds.
Explanation:
The decline in the number of shire horses today can be attributed to several factors. One reason is the mechanization of farming, which has reduced the need for horses in agricultural work. Additionally, the shift towards more urbanized areas has led to a decline in demand for horses in transportation. Lastly, the breeding of other horse breeds that are better suited for specific tasks, such as racing or show jumping, has reduced the popularity and population of shire horses.

Humans creates a nonbiological impact on coral reefs.
What are coral reefs?
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Moreover, coral reefs are under relentless stress from myriad global and local issues, including climate change, declining water quality, overfishing, pollution and unsustainable coastal development.
Therefore, reef corals build homes for millions of species of marine life, they support healthy ocean food webs, and they protect our coastlines.

How does the structure of a red blood cell help carry out it’s function?
Red blood cells' structure, having a biconcave shape and lacking organelles, maximize their capacity to transport gases. Hemoglobin within these cells bind and transport oxygen and carbon dioxide. Their structural adaptations, like lacking mitochondria, enhances oxygen transport efficiency.
Explanation:The unique structure of a red blood cell enables it to efficiently carry out its primary function, which is gas transport. Red blood cells, also known as erythrocytes, are biconcave discs. This shape provides a greater surface area to volume ratio, which facilitates efficient exchange of oxygen and carbon dioxide.
Erythrocytes are packed with an iron-containing protein called hemoglobin. Each molecule of hemoglobin can bind with four molecules of oxygen, allowing each red blood cell to carry approximately a billion molecules of oxygen. Hemoglobin also helps in carbon dioxide transport.
Red blood cells lack most organelles, providing more room for hemoglobin molecules. Moreover, they lack mitochondria which prevents the use of the carried oxygen for metabolic respiration. These structural adaptations enhance the efficiency of oxygen transport.

When cars age or are poorly maintained, they tend to leak oil onto the roadways and parking lots. This oil is washed into the nearest waterway with the next rainfall. What type of water pollution does this cause
The oil leaks from poorly maintained or aged cars result in water pollution once this oil enters water bodies. The oil creates a surface layer, blocking light and oxygen, impacting the lives of aquatic organisms. Over time, this type of pollution can pose serious risks to the health of humans and other terrestrial animals consuming this polluted water.
Explanation:When cars age or are poorly maintained and leak oil onto the road, this introduces contaminants into an environment when it enters waterways. This kind of pollution is termed as water pollution. The contamination brought about by oil is a particularly serious form of water pollution due to the oil's effects when it enters a body of water.
As the oil has lower density than water, it rises to the surface and can create large coverings known as oil slicks. This creates zones that block light and oxygen from entering the water bodies, leading to harmful effects to aquatic life including the death of phytoplankton and reduced mobility in marine animals. Additionally, oil pollution can also trigger a phenomenon known as eutrophication, a condition in water where increased nitrogen and phosphorus compounds lead to overgrowth and subsequent death of aquatic algae. The contaminated water can also negatively impact the health of humans and other land animals that consume this polluted water through the food chain.
