If you want a molecule that is highly polar, look for one that contains:Term
If you want a highly polar molecule, look for one that contains polar covalent bonds or polarizable groups such as N-H, O-H, F-H, and C=O. Additionally, asymmetry in the distribution of electrons in a molecule can also make it polar.
A polar molecule is one that has a positive and negative end, also known as a dipole.
The polarity of a molecule depends on the difference in electronegativity between the atoms making up the molecule. When two atoms have different electronegativities, the shared electrons will be pulled closer to the atom with the higher electronegativity, creating a partial positive charge on the other atom.
This creates a dipole moment and makes the molecule polar. To identify a highly polar molecule, look for polar covalent bonds or polarizable groups such as N-H, O-H, F-H, and C=O. Additionally, asymmetry in the distribution of electrons in a molecule can also make it polar.

select the characteristics that affect the resilience of an ecological community.
Species evenness, Species Richness and Species diversity are the characteristics that affect the resilience of an ecological community. Thus, option a, b and d are correct.
Species evenness refers to how close in number each species is in an environment. It is mathematically defined as a diversity index, a measure of biodiversity that quantifies how equal the community is numerically.
The number of different species present in an ecological community, landscape, or region is referred to as species richness. Species richness is simply a count of species; it does not take into account the abundances of the species or their relative abundance distributions.
The number of different species represented in a given community (a dataset) is known as species diversity. The effective number of species is the number of equally abundant species required to achieve the same mean proportional species abundance as observed in the dataset of interest.

Why is it helpful to study embryonic structures when determining
evolutionary relationships?
Select one:
All animals look the same as embryos.
All animals have completely different embryonic structures.
Embryos are not used to assign evolutionary relationships; only
adult organisms.
Animals with a shared ancestor may have similar characteristics
as embryos that disappear as adults.
Answer:
Embryology is important to understanding a species' evolution, since some homologous structures can be seen only in embryo development. For example, all vertebrate embryos, from humans to chickens to fish, have a tail during early development, even if that tail does not appear in the fully developed organism.

Maxine Miles runs a marathon in 2 hours and 40 minutes. Most of the ATP for this activity is supplied by the process of aerobic glucose breakdown.
The metabolic processes through which aerobic cells make ATP by using the energy stored in the chemical bonds of meals (for example, glucose) and oxygen are referred to as cellular respiration.
Both cellular respiration (under anaerobic circumstances) and acid lactic fermentation can create ATP in muscle cells (anaerobic conditions).
Since cellular respiration is slower than fermentation and acid lactic fermentation is less effective than cellular respiration, muscle cells adopt this route when the body is running low on oxygen. Oxygen (O2) is needed for aerobic respiration in order to produce ATP. Although proteins, lipids, and carbs are eaten as reactants, the preferred route of pyruvate breakdown in glycolysis—aerobic respiration—requires pyruvate to be delivered to the mitochondria.

which food chain will provide the most energy to the top level consumer
The first trophic level of the food chain has the most energy. This level contains the producers, which are all of the photosynthetic organisms. This includes plants and sometimes photosynthetic bacteria and protists.
Answer:
The food chain that will provide the most energy to the top level consumer will depend on the specific ecosystem in question.
Explanation: However, in general, food chains that involve multiple levels of consumers, such as those that include apex predators, will typically transfer more energy to the top level consumer than those that do not.Apex predators are at the top of the food chain and have few natural predators, allowing them to consume a large amount of energy from the organisms they prey on.

The experiment's correlation between the dependent and independent variables may be invalidated if a control variable changes.
Why is it important to keep some variables constant in an experiment?Relies heavily on constant variables. Without these factors, drawing inferences would be challenging, we wouldn't have internal validity, and any results we did get would be somewhat ambiguous.
So that you can only observe the impact of the one variable (the independent variable) that you are trying to evaluate, all the other variables should be kept constant (you control them). Most experiments, like the one we used, involve more than one controlled variable.

What qualitative effect would you expect each of the following to have on the P50 of hemoglobin?
- decrease in pH from 7.3 to 7.0
- decrease in pCO2 from 50 to 30 mm Hg
- removal of all BPG
A decrease in pH from 7.3 to 7.0 would increase P50, a decrease in pCO2 from 50 to 30 mm Hg would decrease P50, and the removal of all BPG would decrease P50 of hemoglobin.
A decrease in pH from 7.3 to 7.0 would have an increase in the P50 of hemoglobin. This is because a decrease in pH causes a shift in the equilibrium of the hemoglobin-oxygen binding reaction towards the left, meaning that hemoglobin will release more oxygen at a given partial pressure of oxygen.
A decrease in pCO2 from 50 to 30 mm Hg would have a decrease in the P50 of hemoglobin. This is because an increase in the partial pressure of carbon dioxide causes a shift in the equilibrium of the hemoglobin-carbon dioxide binding reaction towards the right, meaning that hemoglobin will bind more carbon dioxide at a given partial pressure of carbon dioxide.
Removal of all BPG (bisphosphoglycerate) would have a decrease in the P50 of hemoglobin. This is because BPG is a molecule that binds to the hemoglobin molecule and stabilizes the deoxyhemoglobin form. Without BPG, the hemoglobin will be less stable in the deoxyhemoglobin form and will release oxygen more readily at a lower partial pressure of oxygen.
