<span>1. taxonomy is a branch of science concerned with classification of organisms
hence (5) Classification matches with Taxonomy

2.Species is the biological term referring to the basic unit (smallest rank) of classification:
hence (1) smallest unit of classification matches with Species

3.Arthropods are animals which have an exoskeleton, segmented body and paired jointed legs
hence;
(2) segmented digestive system, appendages, matches with Arthropoda and Animal characteristics

4. Tracheophyta refers to green plants which have conductive tissues (vascular tissues) for conducting water and nutrients through them.
The description " (4) Green, conductive tissue, seeds, flowers, and (7) largest division of plants term, they match with Tracheophyta and Plant Characteristics

5. in taxonomy (organisms classification) the Order, ranks in between Class and Family, hence of families makes an Order.
Therefore, (6) groups of families matches with Order</span>

What happens when chlorophyll and other pigments absorb light?
luda_lava [24]
<span> In the process of photosynthesis, chlorophyll goes into a peculiar excited state which can survive for an unusually long time. Furthermore, the excitation energy can hope from chlorophyll molecule to chlorophyll molecule. In this way a large collection of chlorphyll molecules function as an "antenna" that collects many photons and funnels their energy down to a reaction center, where one particular chlorophyll will lose an electron.</span>

Explain the effects of pre-heating on Pepsi activity​
sladkih [1.3K]

Answer:

Explanation:

Enzymes are biological catalysts; catalysts are substances that increase the rate of chemical reactions without being used up (BBC, 2010), without these catalysts it would take an extremely long time for these reactions to take place. The enzyme used in this particular experiment was pepsin; pepsin is a zymogen of pepsinogen. Pepsinogen is activated by hydrochloric acid, which is released from parietal cells in the stomach lining. The hormone gastrin and the vagus nerve trigger the release of both pepsinogen and hydrochloric acid from the stomach lining when food is ingested. Hydrochloric acid creates an acidic environment, which allows pepsinogen to unfold and cleave itself in an autocatalytic fashion, generating pepsin. (Life Science Network, 2010)

A lot can be learnt about enzymes by studying the rate of enzyme catalyzed reactions, these rates of reaction can be studied in various ways. In this experiment, using a range of different temperatures, the enzyme pepsin will be mixed with egg albumen. This is high in protein and bound to the dye Coomassie blue to gain a light absorbance reading using a spectrophotometer and in effect see how much protein has been digested by the pepsin.
