The answer is D. Chordata.
There are three domains of life - Archaea, Bacteria, and
Eukarya. All organisms that belong to the domains Archaea or
Bacteria have cell walls. In the domain Eukarya, there are some groups
that have cell walls and others that do not.
Chordata is phylum of the kingdom Animalia which belongs to the domain Eukarya. So, Chordata cannot be a domain.
Answer:
Activation energy may be defined as the minimum amount of the energy required to convert the substrate into the product. The higher the activation energy of a reaction, the slower the speed of a reaction.
The enzymes decreases the activation energy of the reaction and increases the effective collision between the substrate. The enzymes does not change the DG (delta G) or free energy of the reaction. The enzymes maintain the equilibrium of the reaction by increasing the equal amount of the forward and backward rate of the reaction.
Gametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”). Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis. This type of life cycle is called a haplodiplontic life cycle
