Answer:
(D) Enzymes can function only within living cells.
Explanation:
<em>Enzymes are biological molecules that are proteinous in nature and speed up the rate of biological reactions.</em>
Option A is true because enzymes are not used up or changed when they are used to catalyze reactions
Option B is true. Enzymes are very specific with regards to the reactions they take part in.
Option C is true. Some enzymes contain non-protein component that assist them in their functioning. These non-protein components are called co-factors.
Option E is true. Because enzymes are proteinous in nature, they can be destroyed/denatured by high temperatures.
<em>The only untrue option is D. Some enzymes can function outside living cells. For example, the enzymes involved in digestion can function not just within living cells but also outside it. The functions of some of the digestive enzymes can be demonstrated in the laboratory.</em>
The correct option is D.
Answer:
The correct genotype would be-
mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.
Explanation:
Listing the genes in the way that they indicates the real combination of alleles is the genotype of individual.
Ability to roll your tongue is a dominant character which has a dominant and a recessive gene. Assume that the dominant allele ‘R’ is for the ability to rolling tongue and the recessive allele ‘r’ for unable to rolling our tongue. As we know mother can not roll her toungue she must have homozygous recessive alleles that means she has two copy of recessive allele. The father could posess any combination of these alleles: RR (homozygous dominant), or Rr(heterozygous dominant).
Thus, the correct genotype would be
mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.
Answer:
Vascular tissue is a complex conducting tissue found in vascular plants that is made up of several cell types. The xylem and phloem are the two main components of vascular tissue. Internally, these two tissues carry fluid and nutrients.
