Answer:
Specificity is the ability of an enzyme to choose exact substrate from a group of similar chemical molecules. The specificity is actually a molecular recognition mechanism and it operates through the structural and conformational complementarity between enzyme and substrate. Enzymes show different degrees of specificity towards their substrate.
Explanation:
Answer:
poliinators and flagellated sperm
Explanation:
Cycads (phylum Cycadophyta) together with Ginkgophyta, Gnetophyta, Pinophyta, Pteridospermales and Cordaitales belong to the gymnosperms (naked seed-producing plants). They are different than angiosperms which produce encased seeds within an ovary.
Cycads (but also Ginkgo) produce swimming sperm that is different than all other groups which produce sperm without swimming flagella.
Also, unlike other groups of gymnosperms, cycads have specialized pollinators, beetls.
A tissue is a group of similar cells and their intercellular materials in a discrete region of an organ performing a specific function. <span>There
are five levels of organization and these are the cells, tissues, organs, organ
systems and organism. The most complex is the organism having the rest of the
organization in it and the least complex is the cell, the basic unit of
structure. The human body tissue is an organized group of cells that is formed to create a muscle or an organ. There are four types of human body tissue: muscle, epithelial, connective and nervous tissue. Each function according to how they are grouped.</span>
<span>muscle cells are animal tissue and therefore cannot undergo photosynthesis. ATP is created by mitochondria, these mitochondria use an electron transport chain to slowly oxidize glucose. The electron transport chain increases the proton concentration on one side of the membrane. ATP synthase uses this proton gradient to form ATP from ADP. This process is called cellular respiration</span>
something that causes an organism to decay. It could have been eaten, or an air pocket formed as it was fossilizing or basically anything that obstructs the formation of a fossil.... you have to figure the rest out; )
