How do polar molecules form hydrogen bonds

Biology

Opposite charges of polar molecules can interact to form hydrogen bonds. The hydrogen bond in polar molecules occurs only in compounds that have hydrogen bonded to N, O, or F. <span>These very highly electronegative</span><span> </span><span>elements</span><span> create a partial positive charge on the hydrogen. </span><span>The H atom is attracted to the partial negative charge on an N, O, or F atom in another molecule.</span>

However, the hydrogen bond is a strong intermolecular bond.

Answer:

Please find the answer to the blank spaces in each statement of the attached image in CAPS.

1. All energy comes from the SUN

2. Plants, algae and some bacteria capture energy by PHOTOSYNTHESIS in their CHLOROPLAST.

3. Plants, animals, fungi, protists, and most bacteria release energy by RESPIRATION in their MITOCHONDRIA.

Note:

- Photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02)

- Respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER

Explanation:

The image in this diagram is depicting how energy flows from the ultimate source, which is the SUN to other living organisms. Plants, algae and some bacteria have the ability to capture energy from the SUN using pigments in their CHLOROPLAST in a process called PHOTOSYNTHESIS, which they use to synthesize their food. The process of photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02) gas.

However, on the contrary, virtually all living organisms including: Plants, animals, fungi, protists, and most bacteria etc. release energy via an organelle called MITOCHONDRIA in a process called RESPIRATION. The process of respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER.

which of the following is not a characteristic of Arthropods that has attributed to their diversity and success A. endoskeleton
ValentinkaMS [17]
A. endoskeleton

Endoskeleton is not a characteristic of Arthropods that has attributed to their diversity and success. Endoskeleton is defined as inner characteristics of the skeletal feature of an organisms such as bears, humans, fish and etc.

Exoskeleton on the other hand is the trait by which arthropods posses. It is skeletal feature that is described outside or is extrinsic, this is evident as crabs have their skeletons outside of their body.

Plsssss help rn and pls don’t guess.
asambeis [7]

Answer:

Punnett Squares are unable to predict the offspring of an asexual organism because there is only one parent from which the offspring can receive genes from. The whole point of a Punnett Square is the fact that it covers all possible  offspring outcomes besides mutations from the usual two parents.
