Answer:
guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck
Most likely located in the nucleus, mitochondria and chloroplasts! The nucleus contains the most DNA!
The answer is B. The specific heat means the heat amount the substance needs to absorb when the temperature increases 1℃. The high specific heat means that it needs a huge amount of heat when increase just 1℃. For A, the dissolved salts can help decrease the freezing point.
Answer:
Gene pairs segregate randomly and independently of each other.
Explanation:
Genes are the basic units of hereditary and are located on chromosomes. According to Gregor Mendel's law of independent assortment which states that the alleles of two (or more) different genes are sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele the same gamete receives for another gene.
For example, in a the pea plants used by Mendel in his studies, the genes for seed shape and flower color were inherited independent of each other by the offspring of the parent pea plants. Therefore, Mendel concluded that the inheritance of each trait was independent of the other.
Answer:
The correct answer is - option C.
Explanation:
CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.
As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.
The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.
Thus, the correct answer is - option C.
