B. I, II, III
Mollusks have 3-chambered heat. They have gills and they have 1-way digestion.
Other characteristics of mollusks are:
1) Bilaterally symmetrical
2) Body has more than two cell layers, tissues and organs
3) body without cavity
4) body monomeric and highly variable in form, may possess a dorsal or lateral shells of protein and calcarous spicules.
5) has a nervous system with a circum-oesophagal ring, ganglia and paired nerve chords
6) has an open circulatory system with heart and aorta
7) has a pair of kidneys
8) reproduction normally sexual and gonochoristic
9) feed a wide range of material
10) live in most environment
Answer:
The dominant (light green) parent was heterozygote for the trait
Explanation:
According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.
However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.
Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).
Alfred Russel Wallace, a biologist, naturalist and anthropologist who studied life in the tropics of Indonesia came up with the same idea of natural selection as Charles Darwin and prompted Darwin to publish his Origin of Specie sooner rather than later. He also studied the geographic distribution of species and as as well he was a social activist who criticized capitalism and warned of damage to the environment from man's economic activities.
The solution would be D. Pyruvic acid is produced during glycolysis and travels from the cytoplasm and enters the mitochondrion.
I think it might be Stratosphere, if Ozone layer is an option I will suggest that too.
