where does pollination takes place in the flower
Answer:
To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

Which of the following does NOT affect the flow of groundwater through an aquifer ? a. porosity C. gradient b . chemical weatheringd. permeability
Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.

Which can more efficiently supply nutrients and
expel waste products?
A. larger cells
B. smaller cells
C. cells with lower surface area to volume ratio
D. cells shaped like a cube
Answer:
Smaller Cells
Explanation:
Basically, small cells have larger surface area but smaller volume, its vice versa for larger cells.
Not to forget that the functions of a cell are related to the diffusion, osmosis and active transport movement.
Factors to consider for a faster diffusion/ osmotic movement includes:
Surface Area
Size of molecule
Difference in concentration gradient
Temperature
Distance
So as per the factors, when there is a larger surface area, the rate diffusion/ osmosis increases hence increasing its efficiency.
Humans use special body parts for functions such as breathing and breaking down food. Some living things, such as bacteria, are too small to perform these functions. True false Submit
Answer:
False
Explanation:
Bacteria do not have organs like humans. However, bacteria have specific structures to perform certain essential functions.
Among the bacteria, there are the respirators, which perform aerobic cell respiration, where oxygen gas is the final acceptor of hydrogen ions. Also, some bacteria perform anaerobic cell respiration. In those, oxygen gas is replaced by other molecules, which function as hydrogen acceptors such as nitrates or sulfates. Bacteria respiration occurs through the mitochondria.
In addition, bacteria can have different forms of "obtaining food"
Some can obtain their food through photosynthesis, degrading organic compounds. Other types of bacteria use the energy released in oxidation reactions of inorganic compounds, such as those that participate in the nitrogen cycle.
Finally, there are saprophagic bacteria, which obtain food from corpses and the remains of living beings, and the parasite ones, which find this food in the tissues of living beings, often causing them illness.
How does mutation change allele frequency
A. It forces evolution to happen by introducing new adaptions.
B. It causes some individuals to go extinct because their mutations hurt their chance of survival.
C. It adds new genes into the gene pool that didn't exist there before.
Answer:
C. It adds new genes into the gene pool that didn't exist there before.

community? Use the words recycle, trophic level,
and flow in your answer. (2.4-2.6)
Answer:
47.. in this case , the longer the food chain , the less energy is available for the rest of the members of the food chain. this indicates that a food chain with 15 trophic levels contain an energy that is insufficient to sustain all its members
48...Matter is cycled through the ecosystem in the biogeochemical cycles. ... However, energy is not recycled, but it flows into the ecosystem through the feeding relationships between the organisms in different trophic levels.
49.. (a) ...Urban development can magnify the risk of environmental hazards such as flash flooding. Pollution and physical barriers to root growth promote loss of urban tree cover. Animal populations are inhibited by toxic substances, vehicles, and the loss of habitat and food sources.

Which term refers to the energy an object has due to its position?
Answer:
Potential Energy.
Explanation:
Potential energy, stored energy that depends on different parts of the system's relative position. When compressed or stretched, spring has more potential energy.
A stainless steel ball has more energy than it had when it fell to the world. It is able to do more work in the raised position.
Potential energy is a system's property and not a single body or particle. The earth-consistent system and raised ball, for instance, have greater potential energy as the two are more distinct.

What would happen if a populations chose their mates randomly?
A. Allele frequency would be constantly changing at random
B. The allele frequency would stay relatively the same over time because there are no traits that are being selected for.
C. Randomly mating allows the most beneficial traits to be passed on because more individuals are going to select for them.
D. Allele frequency would begin to favor the dominant trait.
Answer:
B. The allele frequency would stay relatively the same over time because there are no traits that are being selected for.
Explanation:
Like recombination, non-random mating can act as an ancillary process for natural selection to cause evolution to occur. Any departure from random mating upsets the equilibrium distribution of genotypes in a population. This will occur whether mate selection is positive or negative assortative.

Microbeads are tiny, smooth, plastic spheres found in common household products such as facial soap. These beads, measuring from 0.0004 to 1.24 mm, roughly the size of some fish eggs, are too small to be removed by water treatment systems. Thus, they end up in rivers, lakes, and other bodies of water. The accumulation of these microbeads is an environmental concern for aquatic biologists because microbeads
(1) make the lakes and rivers cloudy and dirty, affecting their appearance
(2) may stick to some household water pipes, preventing drainage problems
(3) could be mistaken for food by some species, working their way up the food chain
(4) could clog fishing nets, affecting the ability of fishermen to catch fish
Answer:
(3) could be mistaken for food by some species, working their way up the food chain
Explanation:
Microbeads, such as other microplastics, can affect wildlife in many ways, but mostly by
IngestionIntroduction and transference in the trophic webInteraction with other contaminantsMicroinvertebrates, bacteria, and viruses colonize these microplastics and can be transported long distances.Organisms like mollusks, crustaceans, fishes, birds, turtles, among many others, might confuse these elements with food and eat them. Microbeads might float or accumulate in sediments and be ingested by different benthonic species. The ingestion of microbeads by inferior links in the trophic web means a direct entrance in the trophic web where many superior links are affected too while feeding with already contaminated prey.
The ingestion of microbeads can cause a significant impact on the growth, development, and reproduction of freshwater and seawater species.
Microbeads, like other microplastics, characterize for their durability in time and resistance, which means that the ones that are already in the oceans and rivers will last there for centuries.
Which of the following can cause evolution to occur? (Select all that apply)
Mutation
If organisms choose a mate for a specific reason
People moving into or out of an area
If the population shrinks
Answer:
MutationIf organisms choose a mate for a specific reasonPeople moving into or out of an areaIf the population shrinksExplanation:
These factors are the "forces of evolution." There are four such forces: mutation, gene flow, genetic drift, and natural selection.
These are the factors that can cause evolution to occur:

Ovaries (2)
Tostos (2)
A. Releases a hormone if blood calcium levels get too high
B. Releases hormones to regulate the endocrine system
C. Regulates the pituitary gland
D. Releases insulin if blood sugar levels get too high
The thyroid gland secretes the thyroid hormones that releases a hormone if blood calcium levels get too high and in this way regulats the calcium level in the blood that is present in option A.
The thyroid gland plays a crucial role in regulating metabolism, which is the process by which the body converts food into energy. Metabolism is a complex process that involves various chemical reactions that take place within the body's cells. The thyroid hormones T4 and T3 are responsible for regulating many aspects of metabolism such as thyroid hormones increase BMR, which means that the body burns more calories even when one is not doing any physical activity.
