<span>The loss
of biodiversity in ecosystems is mostly due to habitat destruction by
the growing human population looking for places to live and food to eat.
Therefore the correct answer is habitat destruction.
I hope this helps.

Sound waves enter the external ear and are funneled toward the tympanic membrane by the shape of the outer ear.Variation in air pressure due to sound waves causes the tympanic membrane to vibrate. The wave frequency will determine the vibration rate.Tympanic vibrations cause the malleus to move. Because the three ossicles are connected, this vibration is transduced to the stapes via the incus.Movement of the stapes vibrates the oval window. Significant amplification of sound waves occurs due to the small size of the window.Pressure changes transduced through the oval window vibrate the perilymph in the scala vestibuli which are transmitted across the vestibular membrane to the endolymph of the cochlear duct, and also up the scala vestibuli and down the scala tympani much the way <span>waves move through the ocean.</span>
Answer:
Major threats to freshwater fishes and other freshwater biodiversity, include: habitat modification, fragmentation, and destruction; invasive species; overfishing; environmental pollution; forestry practise; and climate change.
Hybridization; morphospecies.
Option E is correct.
Hybridization is the process of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization).
Morphospecies: This refers to taxonomic species based wholly on morphological differences from related species.
The above processes (Hybridization and morphospecies) makes the biological concept of large plants complicated.
The answer would be C, structures A and B.
Haploid cells mean that the cells that only have half of the original chromosome number than other cells of the species. For example in human, the original chromosome number should be 46, but haploid cells only have 23 chromosomes. Haploid cells are only usually seen in reproductive cells, which means the cells used for sexual reproduction.
Since flowering plants reproduce sexually, the cells that are haploid are the sex cells. And for sex cells, they include pollen grains (male sex cell) and ovum (female sex cell). According to the picture, pollen can be found in structure B, the anther, and ovum can be found in A, the ovary.
So, your answer is C.
