Answer:
The statement is false.
Explanation:
Passive transport moves molecules from one side of the membrane to the other with the energy of the chemical gradient (or concentration gradient). Otherwise, active transport uses the hydrolyzation of ATP to gain energy in order to move molecules across the membrane without taking into account the gradient.
It increases because the higher you go in the food chain, the bigger the carnivores or consumers are.
Answer:
E
Explanation:
Gregor Mendel discovered the principles that governs heredity. In one of his experiments, he discovered that an organism receives two forms of a gene called ALLELE from each parent. He realized that one allele is capable of masking the expression of its variant pair in a gene. He called the allele that masks or is expressed, DOMINANT allele while the allele that is masked, RECESSIVE allele. He termed this principle the LAW OF DOMINANCE.
The above explained law of dominance is what applies in the question here. When the homozygous round allele and wrinkled allele were crossed, the allele for round seeds are dominant over the allele for wrinkled seeds (recessive) i.e. in a heterozygous state (combination of the different alleles), the round allele will mask the phenotypic expression of the wrinkled allele, expressing itself over it.
Answer:
Option B, Snakes and lizards share a common ancestor.
Explanation:
From the description provided, it is clear that both the lizard and snake (including pythons) have evolved from the same ancestors which had hind legs. Since both the organism (i.e lizard and snake) underwent evolution (differently) for million of years such that the hind legs in lizard are visible and used even today but the hind legs in snakes are buried in muscles toward their tail ends and are not used. Such features which are not used at all or are poorly used are called as vestigial organs.
Hence, option B is correct
