Osteocytes have important functions in the skeleton. Bone is a dynamic tissue that is constantly being reshaped by osteoblasts, which produce and secrete matrix proteins and transport mineral into the matrix, and osteoclasts, which break down the tissue.
The coiling direction of the snail shell is affected by the maternal genes. All the offspring have left-coiled shells, as the phenotype is determined by the mother's genotype. Thus, option C is correct.
Maternal inheritance has been defined as the effect by which the genes are influenced by the mother's genotype and are a type of non-Mendelian inheritance.
The dextral and the sinistral coiling seen in the snails showing the maternal effect is influenced by the genotype of the mother and is not affected by the father's genotype.
The mother has the cc and the father has the CC genes that when crossed are shown in the image.
From the cross, it is evident that the genotype of the mother snail affects and influences the genotype of the offspring, and hence all the offspring's have the left coiling (sinistral).
Therefore, in option C, the genotype of the mother snail affects the coiling.

Your question is incomplete, but most probably your full question was,
All of the offspring have shells that coil to the left. Why do all of the offspring have left-coiled shells?
A. This trait follows a typical Mendelian pattern of inheritance.
B. Only the father's genotype determines the phenotype for shell coiling.
C. Only the mother's genotype determines the phenotype for shell coiling.
D. Shell-coiling is a sex-linked trait.
B. An increase in the number of other grazing animals.
C. An increase in restrictions on the hunting of impala.
D. A reduction in the population of the other impala### predators.
The correct answer is B. An increase in the number of other grazing animals.
Explanation:
In ecosystems, one of the factors that can lead to the decrease of the population of an organism is competition, this occurs as organisms struggle to get the same resource such as food, water or shelter. Additionally, competition increases as more organisms need the same resource. This implies in the case of the impala that feeds on grass and plants if there is an increase in the number of other grazing animals, competition would increase and this would lead to a decrease in the population as some Impalas might not get enough food to survive.

Answer: The correct answer is 1%.
In a food chain, only 1% to 2 % of the total available solar energy is transferred to the producers. The rest 98% to 99% of the solar energy is reflected by the leaves and other surfaces on earth, which is then absorbed by some other materials that convert it into heat.
Thus, 1% solar energy is available to the producers in order to synthesize their food in the process called photosynthesis.
B. An oak tree grows from the seed material in an acorn.
C. Water drips from underneath an oak tree leaf in the morning.
D. Sediment from an area where oak trees were cut down builds up alongside a stream
The example that demonstrates that all cells come from pre-existing cells is an oak tree grows from the seed material in an acorn (option B).
The cell theory is the scientific theory that all living organisms are made of cells as the smallest functional unit.
One of the components of the cell theory is that all cells come from already existing cells i.e. new cells form from cells that are already in existence in a process of reproduction.
The example of this is a tree that grow from a germinating seed. Hence, option B is correct.
