Answer:
We can classify organisms on the basis of its physical features.
Explanation:
Classification of animal is related to its adaptational features because adaptational features of an organism provides information about the organism to which specific kingdom or phylum the organism belongs. These adaptational features are gained by the organisms due to different environmental as well as climatic conditions the organism have which make changes in the body features of an organism. So we can classify organisms on the basis of its physical features.
Answer:
it is important because it helps us identify and name all the animals on earth
b. cells all arise from pre existing cells
c. cells are the basic living units of structure an function
d. all of above
Answer: D
Explanation: I Got it right
Answer:
Sample Response: Plant cells are square because they have cell walls. A cell wall is a rigid structure that gives shape to the cell and helps the plant stand up straight.
Explanation:
Answer:
R1 and R2 exhibit codominance.
Explanation:
In the given plant, pleiotropic locus regulates both berry color and berry size. The R1 allele gives red berries while the R0 allele is responsible for white berries. The heterozygote R0R1 also has red berries, which means that R1 is dominant over R0 for the color of berries. The R2 allele is responsible for the "small" size of berries in homozygous genotype.
The genotype R0R2 also has small berries, which means that R2 is also dominant to R0. However, the genotype R1R2 imparts red color and small size to berries. In the genotype R1R2, both the R1 (responsible for the red color of berries) and R2 (responsible for the small size of berries) alleles are expressed. This represents the fact that the R1 and R2 alleles are codominant and express themselves in heterozygous R1R2 genotype.
The current understanding of dark matter is largely theoretical due to its nature of not directly interacting with electromagnetism. It can be inferred to exist due to its gravitational effects, representing about 27% of the universe's mass-energy composition. The key candidate for it is Weakly Interacting Massive Particles, suggested by the Supersymmetry theory.
Our current understanding of the nature of dark matter is largely theoretical, as dark matter does not interact with the electromagnetic force and cannot be seen directly with telescopes. However, it is inferred to exist due to its gravitational effects on galaxies and galaxy clusters. Dark matter constitutes about 27% of the universe's mass-energy composition, vastly outweighing ordinary matter. The leading candidate for dark matter is currently the Weakly Interacting Massive Particles, or WIMPs. The existence of WIMPs is suggested by the Supersymmetry theory in particle physics, and several experiments are ongoing to detect WIMPs directly.
