Answer:

Impacts from human activity on land and in the water can influence ecosystems profoundly. Climate change, ocean acidification, permafrost melting, habitat loss, eutrophication, stormwater runoff, air pollution, contaminants, and invasive species are among many problems facing ecosystems.

Vinil7 [7]

The genotype of the control bulls he should use to test for the heterozygous genotype is homzygous recessive. A creature can be homozygous dominant, on the off chance that it conveys two duplicates of a similar overwhelming allele, or homozygous recessive, on the off chance that it conveys two duplicates of a similar passive allele. Heterozygous implies that a living being has two unique alleles of a quality.

Which statements below accurately describe trophic levels within ecosystems? CHOOSE ALL THAT APPLY.

ankoles [38]

The true statements are:
Only a fraction of matter consumed at lower trophic levels is transferred to higher trophic levels to produce growth and release energy through cellular respiration.
And
There are fewer organisms at the higher trophic levels of a food web.
These first statement is actually the reason for the second.

You have been hired as a field assistant for a researcher interested in the evolution of flower characteristics in orchids. Comp

chubhunter [2.5K]

Answer:

$\text{Present a flower with one characteristic changed to the normal pollinator. }$ $\text{As a control, present a flower with no characteristics changed to the normal pollinator}$

$\text{Record any measure of pollination success}$

$\text{Repeeat for flowers with other characteristics changed}$

$\text{Analyze the data to determine which altered characteristics affect pollination }$ $\text{success the most. This characteristic will be the result of the experiment.}$

Explanation:

The missing information is attached below.

$\text{Present a flower with one characteristic changed to the normal pollinator. }$ $\text{As a control, present a flower with no characteristics changed to the normal pollinator}$

For the control, you'll need something you're already familiar with. In this scenario, a normal flower with no changes in characteristics is the best control. And if no data is accessible, you still have data on the success rate of a typical flower, which can be used as a guideline. And, for the initial configuration, you can only adjust one characteristic so it would be easier to maintain track of and analyze the data gathered.

$\text{Record any measure of pollination success}$

Since the aim of your experiment is to examine the influence of flower characteristics on pollination performance, you should keep track of the active pollination events. To have more accurate results, this would require listing the total number of plants that were to be pollinated.

$\text{Repeeat for flowers with other characteristics changed}$

Once you've completed the initial examination, you'll need to run tests on various characteristics to see whether they have some impact on pollination performance. To see the importance of different characters on pollination, change only one trait in flowers; if you'd like to research combined results, create pairs and change them together.

$\text{Analyze the data to determine which altered characteristics affect pollination }$ $\text{success the most. This characteristic will be the result of the experiment.}$

Your outcome is also the one that has gotten the most constructive or negative reviews. If some changed characteristic significantly affected the number of pollination efficiency, that is your outcome, because that is what you can mention as a good result and pollination enhancer.

What 4 key elements does carbon bond with in biomolecules

nordsb [41]

Answer:

The unique properties of carbon make it a central part of biological molecules. Carbon binds to oxygen, hydrogen, and nitrogen covalently to form the many molecules important for cellular fuction. Carbon has four electrons in its outermost shell and can form four bonds.
