Answer:
It only records trends in population at fixed locations in the ecosystem.
Explanation:
The point count method is a method used to monitor the populaton of birds in certain places that consists on having someone fixed at one spot and record all the birds that he can spot by sight and by ear, so if he sees or hears a certain bird he records it, to have a close idea of the species of birds that there are in a certain location, the problem would be that it only records trends at fixes locations in the ecosystem.
1. Naked Seeds, Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.
Two main factors that affect enzyme activities are temperature and pH value.
Every type of enzymes has their own optimum temperature and pH, where they work the fastest at.
for temperature, if the temperature is too low for the enzyme, they may become inactive, they work slow. Give them their suitable temperature they'll work fast again.
However, if the temperature is too high, the enzyme would be denatured. You cannot use them again.
Denatured enzymes means the enzymes already changes shape of the active site and can no longer bind into substrates and therefore no longer works, no matter if you provide the suitable environment again.
For pH, the concept is same, unless if the pH value is too extreme than the optimum pH, the enzyme will be denatured instead of being inactive.
Answer;
-Citrus trees are angiosperms and dicots. Citrus tress have herbaceous or woody stems.
Explanation;
-Angiosperms are vascular flowering plants. They are divided into two classes: the monocotyledonous (monocots) and the dicotyledonous (dicots). This distinction is based on the number of cotyledons, the food storage structures in their seeds. Monocots have one cotyledon while the dicots have two.
-Citrus tree is an example of Angiosperm, dicotyledonous plant. Additionally citrus tree have herbaceous or woody stems.
