Answer: Option C) Animal
The cell wall is tough, flexible and fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides cells with structural support and protection. All BUT ONE type of organism has cells with cell walls. That is an animal
Explanation:
One distinguishing feature of animal cells compared to other living cells is the absence of cell wall.
However, the animal cell possess a cell membrane, with which it regulates substances entering or leaving the cell, and also provide protection and mechanical support for the cell against foreign invaders such as pathogens.

Answer:
(a) Gg × Gg; (b) genotypic = 1:2:1, phenotypic = 3:1
Explanation:
a) A cross between two gray seeded plants produces progeny with gray and white seeds in 3:1 ratio (302:98=3:1). This means that the parent plants are heterozygous and each has at least one recessive allele. If the allele "G" is responsible for gray seed and the allele "g" imparts white color to the seeds, the genotype of the heterozygous parents would be "Gg".
b) A cross between two heterozygous gray seeded parents would produce progeny in following ratio:
Genotype ratio= 1 GG: 2 Gg: 1 gg
Phenotype ratio= 3 Gray: 1 white
Efferent nerve any nerve that carries impulses from the central nervous system toward the periphery, such as a motor nerve
'Red shift' is a key concept for astronomers. The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum.
Hope this helps.
