It’s actually D!If the prey can’t eat enough food because of limited plants they die off which means the predators die off!
Answer:
Transosteal
Explanation:
One of the ways to get a missing or broken tooth fixed is through dental implants. It can also be used to fix loose teeth. For this to occur, a tooth root is needed to hold in place the dental prosthesis. Dental implants involve surgically fixing of metal frames (surgical component) into the jawbone beneath the gum to serve as the tooth root. This surgical implant, which now serves as a tooth root, enables the dentist to fix a replacement tooth.
<em>Transosteal implant</em> is a type of dental implant in which the surgical component is a U-shaped metal frame or pins that is inserted into the lower jaw followed by the replacement tooth on top during tooth replacement.
Explanation:
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.

Answer:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis.
Explanation:
The pairing of homologues at the beginning of meiosis I ensures that each gamete receives one member of each pair. The pairing of homologues brings together the near-identical sequences found on each chromosome, and this sets the stage for crossing over.Following crossing over, at least two of the four chromatids become unique, unlike those of the parent.The frequency of recombination is not uniform throughout the genome. Some areas of some chromosomes have increased rates of recombination, while others have reduced rates of recombination . Recombination or crossing over occurs during prophase I. Homologous chromosomes – 1 inherited from each parent – pair along their lengths, gene by gene. Breaks occur along the chromosomes, and they rejoin, trading some of their genes. The chromosomes now have genes in a unique combination.Independent assortment is the process where the chromosomes move randomly to separate poles during meiosis. A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes.
This reshuffling of genes into unique combinations increases the genetic variation Slightly different sequences in the genetic code of different individuals from the same species. This is important for species adaptation to occur in a population and explains the variation we see between siblings with the same parents.
