explain why there is a greater efficiency in supplying plants as human food
Answer:
Does this help?
Explanation:
Plants are very efficient when it comes to supplying for people. Plants not only allow us to breath, but we can also feed off them. We can always grow plants. Planting is also better for the environment. Less people will pay for fruits and vegetables. Even with all the advantages of just supplying plants as human food, it would be almost, if not impossible to feed the entire population all year off salads.

An ecosystem, also known as an ecological system, is made up of all the organisms and the physical setting in which they live. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue. Animals play a significant part in the transfer of materials and energy through the system by eating plants and one another.
They also have an impact on the biomass levels of the microbial and plant communities. In addition to facilitating nutrient cycling by transforming nutrients held in dead biomass back into a form that can be easily utilized by plants and microorganisms, decomposers also release carbon into the atmosphere through the breakdown of dead organic matter.

Answer:
hope it helps...stay safe healthy and happy..If a mutation causes you to get a new trait, by how natural selection works, that trait will disappear even if it will help you survive T or F
Answer:
False, natural selection would not cause the mutation to die out unless it harms reproductivity
Explanation:
Natural Selection works through many different aspects, here we see that a creature has developed a mutation. If the creature would be aided with this new found mutation it would not simply disappear. The creature would end up reproducing with similar creatures spreading this new mutation, and this is what natural selection is. Natural selection is when creatures with negitive mutations are unable to reproduce causing their gentic line to die out, while creatures with superior genetics continuously reproduce.

How do we know a particular lineage of prokaryote exists in a natural habitat without first isolating and growing it in laboratory culture
The use of DNA-based techniques is one way to ascertain whether a certain lineage of prokaryote occurs in a natural habitat without first isolating and cultivating it in laboratory culture.
These methods allow researchers to identify species of prokaryotes without having to isolate and grow them in culture. The most common DNA-based method is called PCR (polymerase chain reaction) which is used to amplify and detect the presence of specific DNA sequences in a sample. By designing primers specific to a particular prokaryote, researchers can determine if the organism is present in a given sample, even if it is present in very small amounts.
Other methods such as denaturing gradient gel electrophoresis (DGGE) and 16s rRNA gene sequencing can also be used to identify different species of prokaryotes in a sample. These methods allow researchers to determine if a particular lineage of prokaryote exists in a natural habitat without having to isolate and grow it in laboratory culture.

Answer: The answer is A. Increaed use of fossil fuels.
Explanation:
A prey population consists of individuals with a variety of reaction times. The adaptation that allows some of these animals to react faster would be an example of natural selection if it helps them a. Reduce the mortality rate of the population
b. Reproduce and increase gene frequency in the population
c. Survive and mate
d. Produce offspring that can react at an average speed
The correct answer is option (A) Reduce the mortality rate of the population.
Natural selection is a pressure that causes groups of organisms to change over time. Animals inherit their genetics from their parents or ancestors, and the environment is constantly changing. So, no organism is perfectly adapted to its environment. Thus, natural selection is constantly influencing the evolution of species.
The environment will change, even if a parent was perfectly acclimated to it, leaving the offspring poorly adapted to it. Only the best and fittest organisms can reproduce since there are many species and few resources. Natural selection, which is thought of as the environment and forces acting to prevent organisms from surviving and reproducing, operates against all living things. As a result, living things have the ability to pass on their DNA to the next generation. These DNA sequences are "selected" for by this.

The ratio is 0.89, and the cells are less efficient at transferring oxygen.
Hereditary spherocytosis (HS) is a red blood cell condition that causes the cells to be smaller and spherical rather than the normal flattened, biconcave form. Normal red blood cells have an average diameter of 7.2μm, while red blood cells in people with HS have an average diameter of 6.7μm. The typical surface area of a normal red blood cell is 136μm^2 and its volume is 91μm^3.
Hereditary spherocytosis is a blood condition that runs in families. It occurs as a result of an issue with the red blood cells (RBCs). The cells are not formed like a disc, but rather like a spherical. These red blood cells (known as spherocytes) are more delicate than disk-shaped RBCs.

What happens to the 3 carbon sugar that exits the Calvin cycle?
By carbon fixation, 3-PGA molecules are transformed into glucose molecules, which are simple sugar molecules.
It corresponds to the second phase of Calvin's cycle. By carbon fixation, 3-PGA molecules are transformed into glucose molecules, which are simple sugar molecules. Energy for this stage is provided by ATP and NADPH generated during the light-dependent activities of photosynthesis. Thus, the Calvin cycle is a mechanism through which plants convert solar energy into compounds like sugars that may be stored for a long period. ATP and NADPH provide the sugars with their energy.
This procedure is referred to as reduction because 3-PGA molecules get electron transfers to produce glyceraldehyde-3 phosphate.
