Answer: B increasing atomic number
Explanation: A periodic table is the table that shows the arrangement of elements in the order of increasing atomic number. In the periodic table, the horizontal rows of elements are called periods while the vertical columns are called groups. All the elements in a given period have the same number of electron shell while all the elements in the same group have the same number of valence electrons (same number of electrons in the outermost shell of their atoms).
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.

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).
Over the past 60 years, the level of carbon dioxide in the atmosphere has been continually increasing. Many scientists hypothesize that this increase has led to an imbalance in the carbon cycle and a climatic trend known as global warming.
In which of the following ways could humans help the carbon cycle return to normal?

which group of plants lacks true roots, stems, and leaves?
Answer:
Bryophytes (LIverworts, hornworts, and mosses) lack true roots, stems, and leaves.
Explanation:
The bryophyte is slightly differentiated, but they do not have true roots, stems, and leaves. The rhizoids are something similar to roots bryophytes have in their plant bodies.
The main plant body of the bryophytes is more like a thallus. Bryophytes are spore-producing plants that do not have vascular tissue.
Hence, bryophytes are the plants lack true roots, stem, and leaves.
This type of physical weathering occurs in places where there is a large change in daily temperatures, and it can lead to the significant stress on the outer layers of the rocks.

how does acid deposition impact aquatic environments?
a. fish do not often die but they do become too full of toxins to be consumed by humans.
b. aquatic environments become temporarily lifeless while new species of fish who can tolerate the acid deposition replenish the stock.
c.fish that absorb the chemicals either die, become sterile or produce mutated offspring, and are too full of mercury to eat.
d. aquatic environments are not directly impacted by acid deposition.
Your correct answer will be. C. fish that absorb the chemicals either die, become sterile or produce mutated offspring, and are too full of mercury to eat. Because, effects of the acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife.
hope this helps others that come to this question.
Acid deposition impacts aquatic environments because fish that absorb the chemicals either die become sterile. Also, they produce mutated offspring and are too full of mercury to eat.
Further Explanation:
Acid rain includes all types of precipitation with acidic content with a pH value of less than 7. These types of precipitation are harmful to aquatic animals and their infrastructure. Acid rain is the result of the reaction of Sulfur dioxide and Nitrogen oxide with water molecules present in the atmosphere.
Acid deposition is referred to all kinds of precipitation, smog, fog, and mist that have acidic content in it. Deposition can be dry or wet, but in all states, it is hazardous for the environment. The deposition generally has a pH value of less than four and can have pH value as a minimum of 1.5. Sulphuric acid and Nitric acid are two components generally found in the deposition. These acids clog the gills of fish and cause chronic stress. Also, the calcium level because of the acid is lowered and therefore, they are not able to produce the egg.

Which of these creates a nonbiological impact on coral reefs ?
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.

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.

what is a concentration gradient? what does it mean if a molecule diffuses down it's concentration gradient?
A concentration gradient refers to the difference in the amount of a substance from one area to another. When molecules diffuse down this gradient, they move from a high concentration zone to a lower concentration zone until they spread out evenly, achieving equilibrium.
Explanation:A concentration gradient in biology refers to the variation in the concentration of a substance within a specific area. This gradient is established when there is a difference in the amount of molecules or ions between two regions. Molecules move from an area where they are in higher concentration to regions of lower concentration, a process known as diffusion.
When a molecule diffuses down its concentration gradient, it moves from an area of high concentration to one of lower concentration. This is a passive process that doesn't require any energy as the molecules are simply spreading out to equalize their concentration. This diffusion continues until the substance is evenly distributed, or equilibrium is achieved, thus eliminating the concentration gradient.
Therefore, the phrase 'diffusing down a concentration gradient' means essentially the same as 'moving from an area of high concentration to an area of low concentration'. Examples of this process include the movement of oxygen molecules from your lungs to your blood and the diffusion of nutrients across a cell's membrane.
