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.

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.

The water cycle affects all living things. Humans have polluted the water making it unsafe and in some cases not suitable to support life.
The chosen cycle is carbon cycle
How organisms are part of cycle?
Carbon is one of the main elements of organic matter constituting living beings. It is the plants that fix it during their growth, from the CO2 present in dissolved form in the oceans or in gaseous form in the atmosphere. It is then either released into the air or water by respiration, or sequestered more or less long in the soil and seabed. The carbon cycle plays a decisive role in the greenhouse effect, whether natural or not, given its influence on the concentration of CO2 present in gaseous form in the atmosphere.
How does the activity impact the cycle?
Carbon dioxide and methane alone account for ¾ of the problem of global warming. Indeed, the arrival of industry has turned the cycle upside down, it has caused a sharp increase in the concentration of greenhouse gases in the atmosphere that has amplified the greenhouse effect and global warming.
In April 2014, CO2 concentrations reached 400 ppm throughout the northern hemisphere, bringing us closer and closer to the 450 ppm considered dangerous for the planet's climatic equilibrium.
The step we can take to reduce the impact:
Man must react, if we do not remedy this increase in CO2 emissions, melting ice could cause an increase in ocean level of about 70 meters. To avoid this, a goal has been launched, it would reduce our CO2 emissions by 4. But for this it should first of all that men become aware of its responsibility in global warming if we want to hope that there is change.
Man has a great responsibility in global warming that could have a lot of damage on the planet. Showing the importance of the carbon cycle helps prevent future hazards.

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).
why can't an organism survive with just fermentation

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.

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.

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.
How can the rate of a reaction be increased?
A- lowering the temperature
B- decreasing the amount of reactants
C- having less surface area
D- adding a catalyst
HI there!
This Answer Can Easily Be Found By Analyzing What Increases the reaction rate.Several factors can increase the rate of a chemical reaction. In general, anything that increases the number of collisions between particles will increase the reaction rate, and anything that decreases the number of collisions between particles will decrease the chemical reaction rate.
INCREASE THE CONCENTRATION OF THE REACTANTS
A higher concentration of reactants leads to more collisions per unit time and leads to an increasing reaction rate.
INCREASE THE PRESSURE OF GASEOUS REACTANTS
Changing the pressure of gaseous reactants is, in effect, changing their concentration. The increased number of collisions caused by a higher pressure generally increases the reaction rate.
DECREASE THE PARTICLE SIZE OF SOLID REACTANTS
Reaction depends on collisions. If a reactant is a solid, grinding it into smaller particles will increase the surface area. The more surface area on which collisions can occur, the faster the reaction.
INCREASE THE TEMPERATURE
Usually, an increase in temperature causes an increase in the reaction rate. A higher temperature means that the molecules have a higher average kinetic energy and more collisions per unit time. It also increases the number of collisions that have enough energy to cause a reaction to take place.
CHANGE THE SOLVENT
The rate of a chemical reaction depends on the medium in which the reaction occurs. The reaction may go faster in an aqueous solution than in an organic solvent or in a more polar solvent.
ADD A CATALYST
Catalysts lower the activation energy of a chemical reaction and increase the rate of a chemical reaction without being consumed in the process. They do this by an alternative mechanism that has a lower activation energy.
Analyzing the answers Given from A-C These answer have something to do with Decreasing. By decreasing The Temperature,Amount of reactants, And having less surface area will only Decrease our reaction rate.

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.
