The answer would be C because photosynthesis takes in carbon dioxide and water and produces oxygen and glucose. Along with this animal cells do not contain chloroplasts
Answer: The diffusion of ions along the axoplasm is faster,in myelinated compare to unmyelinated,
Neurons are the structural and functioning units of nervous system.They are the vehicles for transmission of impulses as electrical signals from one part of the cells,and from one part of the body to another.
The basic structural components of a typical neuron are the cellbody, the axon, and the dendrites.
Based on structure neurons are classified as myelinated and unmyelinated.This is based on the the surrounding layer of myelin sheath around the axon. The myelin provides the insulating layer for the axon.And ensures fast movement of impluses.
In myelinated neurons the myelin sheath are interrupted at intervals by gaps along the length of the axon called Nodes of Ranvier. These gaps contains more Na-K channels for influx and out-flux of K and Na+ ions for transmission of impulses.
The cytoplasm of axon is called axoplasm,Since this is surrounded by myelin sheath which contains Na-K+ channels,The rate of diffusion of ions along these channels is faster for depolarization to take place than in unmyelinated neurons. Inaddtion as these ions diffusion increases,its jump faster at the nodes of Ranvier (saltatory conduction) to the next axoplasm which further speed up the rate of transmission.
Unmyeinated lacks myelin sheath,therefore the exchange and the rate of diffusion of ions along the axons is low.

Answer:
The correct characteristics are -<em><u> tissue, coelom, segmentation, endoskeleton, and backbone</u></em> from top to bottom boxes.
Explanation:
This phylogenetic tree showing the evolution and relatedness of the different organisms on their shared characteristics. In the given phylogenetic tree there are some characters are missing and we can predict or state them on the basis of evolution and studying the characteristics.
After the Porifera phylum tissue-level organization is found in the organism hence Tissue would be placed in the first box.
The coelom is found organisms above the Nematoda level, which further include a character segmentation in Annelida and Arthropoda. Another lineage from arising with the coelom organism that included endoskelton and backbone.
Thus, The correct characteristics are - tissue, coelom, segmentation, endoskeleton, and backbone from top to bottom boxes.
In most animals, the <u>diploid</u> state of the life cycle is much larger than the <u>haploid</u> state.
The multicellular diploid stage is the most evident life stage in a diploid-dominant life cycle, and the only haploid cells are the gametes. Most animals, including humans, have this kind of life cycle. It is much larger than the haploid life cycle because of the complexity due to diploid stages.
The multicellular (or occasionally unicellular) haploid stage is the most visible life stage and is frequently multicellular in a haploid-dominant life cycle. The only diploid cell in this kind of life cycle is the single-celled zygote. This kind of life cycle is found in some algae and fungi.
Meiosis, which produces haploid cells from diploid ones in all sexually reproducing species, and fertilisation are two examples of fundamental life cycle characteristics that all sexually reproducing species share (the fusion of haploid gametes to form a diploid cell called the zygote).
