5. Occurs when forces acting on an object
direction will stay the same.
equal. ( i’ll give 10 points)
Answer:
Net Force = The combination of all forces acting on an object is called the net force. Whenever there is a net force acting on an object, the forces are unbalanced. Unbalanced forces can cause an object to start moving, stop moving, or change direction.
Explanation:
When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a stationary object stays still.

Another source for sulfur is from pollution cases by man-made activities. These are mixed with water in the air falling in
Answer:
rain
Explanation:
Sulfur dioxide pollutants can be generated in the form of aerosols and acid rain. Acid rain is a type of acid deposition which results from the rain with has a pH of 5.7 (or even more acid). The process of oxidation of sulfur-containing compounds is the main cause for the generation of sulfur dioxide pollutants that are released into the atmosphere by human activities (e.g., as a combustion product from burning coal and other fossil fuels).
What are the types of vascular plants? How do they reproduce?
crytogams - this type of vascular plant reproduces by spore.
phanerogams - this type of vascular plant reproduces from the seeds, hence also named as seed plants.
Angiosperms - this type of vascular plant reproduces flowers and fruits
Gymnosperms - this type of vascular plant reproduces cones and seeds only.
Answer:
Vascular plants are plants that have roots, stems, and leaves. They have a vascular system that is responsible for the distribution of water and nutrients. This system is made up of the xylem (responsible for distributing the raw sap to the leaves) and the phloem (responsible for transporting the processed sap to the rest of the plant). Within this group we have: pteridophytes (Many plants do not produce flowers. They are also known as cryptogams. They reproduce through spores) and spermatophytes (they are vascular plants that produce seeds and, therefore, are the most evolved).
Explanation:
Vascular plants are those that have a “corm” made up of root and stem (stem and leaves), as well as a conduction system made up of xylem and phloem for transporting water and photosynthates. Pteridophytes are vascular plants that do not produce seeds. Within the vascular plants they are the simplest plants at a structural level, since they do not have the complexity linked to the production of these seeds, which are what allow the sexual reproduction of plants. Spermatophytes are the vascular plants that produce seeds. These seeds generated by the flowers, when they fall to the ground after dispersing, germinate and give rise to a new plant. This presence of seeds that can be spread by the wind or by animals is what has allowed these plant species to colonize the world.
Explain how this experiment showed that gene flow was not the cause of antibiotic resistance.
Answer:
Due to no transfer of resistance allele.
Explanation:
The gene flow was not the cause of antibiotic resistance because the characteristics can't be transferred from one generation to the next generation. The organisms are evolved to become an antibiotic resistance due to their environmental conditions and this resistance quality is only present in the existing population and the alleles that are responsible for this resistance can't be transferred from the bacteria to the next generation so the experiment showed that gene flow was not the cause of antibiotic resistance

Which of the following is not a contributing factor to ecosystem stability species, genetic,ecosystem, or abiotic diversity.
Answer:
Ecosystem.
Explanation:
Ecosystem is not a contributing factor to ecosystem stability whereas, species, genetic, and abiotic diversity are the factors that contributes in the stability of an ecosystem. The diversity of species greatly affected the ecosystem stability if more species are present in he ecosystem. The abiotic factors also plays an important role in the stability of an ecosystem because these abiotic factors causes changes in the ecosystem environmental conditions.

Which level has the most number of organisms but the least specific characteristics?
Answer:
Kingdom
Explanation:
Out of all the taxonomic categories, the Kingdom is the least specific, which means it has the least filters.
I like to think of taxonomic categories as filters/sieves. If you put your animals through the Kingdom filter, then all the animals are in that category. if you have a finer sieve, then less animals get through, this goes down all the way to the most specific which is Species.

What are the reactants and what are the products of cellular respiration?
Reactants:
Products:
Answer:
Reactants: Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Products: Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Explanation:
the redwood groves in northern california are one of america's greatest natural resources. redwoods can live more than 2,000 years and grow taller than 350 feet. when tourism became popular in the late 1800s, large tunnels were cut through the center of several of these giant trees to allow wagons to pass through (and to attract tourists to the location). even today, visitors wait in line to be photographed driving their cars through a tunnel. when the groves were converted into national parks, the tunneling was discontinued, but several tunneled trees are still alive. when the redwood tunnels were first constructed, not much consideration was given to the long-term effects of a tunnel on a tree's health. nevertheless, many trees have survived more than 100 years after a tunnel was cut through their trunks. this is possible because
Answer:
The secondary vascular tissues (secondary xylem and secondary phloem) are oriented vertically
Explanation:
Secondary growth is common in most woody dicotyledonous and gymnosperm plants. The secondary vascular tissue is formed from the meristematic vascular cambium. The secondary phloem grows on the outermost side of the vascular cambium, while the secondary xylem is deposited on the internal side. This secondary vascular tissue runs vertically, i.e., parallel to the main axis of the organ (stem), thereby it is expected that they are not completely disrupted by the tunnel.

Explanation:
For a neuron to function, an input of free energy from ATP is required to set up the sodium and potassium ion concentration gradients such that a signal can be propagated down the axon of a neuron without the necessity of ATP. The system could have worked the opposite way. The neuron could have used ATP to move ions across when a signal was being propagated and then allow natural diffusion to return the ions to their respective sides of the membrane. What advantage does the organism have using ATP up front
Answer:
The lack of ATP would slow nerve responses to generate an action potential
Explanation:
Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.

Through their roots, plants absorb water and mineral nutrients, returning organic matter to the soil through root exudates, litterfall, and roots. Thus, they can increase organic matter in the soil.
What increases soil quality?Through their roots, plants absorb water and mineral nutrients, and they return organic matter to the soil through litterfall, roots, and root exudates.
Avoid over-tillage while preparing seedbeds, and maintain the seedbed as coarse as you can to keep the aggregates big enough to hold gases and carbon. Any organic material input enhances soil quality. Organic matter enriches the soil with carbon while preserving the separation and integrity of the soil aggregates.

How is an enzyme related to its substrate?
Answer:
An enzyme will interact with only one type of substance or group of substances, called the substrate, to catalyze a certain kind of reaction.
