Answers
Explanation:
answer 1st = seagrasses
( b )1000 meters
1 Kilometer (km) is equal to 1000 meters (m).
answer 2nd = A diameter tape, or d-tape, is the most common tool. The tape is wrapped around the tree, measuring its circumference. The tape is graduated to reflect a conversion from tree circumference to tree diamete
answer 3rd= Snow accumulates on branches and leaves or needles when there is high snowfall. The conical shape of conifer trees (mountain) prevents as much accumulation of snow as there would be on a wider shaped tree. The conical shape of the tree also helps to get the snow to fall off the tree quickly and to get the sunlight.
Explanation:
- a) Thalassia and Zostera
- b) 1000 metres
2. A diameter tape, or d-tape, is the most common tool. The tape is wrapped around the tree, measuring its circumference. The tape is graduated to reflect a conversion from tree circumference to tree diameter. Thus, circumference is measured, but diameter can be recorded to the nearest 0.1 inch
3. A cactus is able to survive in the desert due to the following features: (i) It has long roots that go deep inside the soil for absorbing water. (ii) Its leaves are in the form of spines to prevent water loss through transpiration. (iii) Its stem is covered with a thick waxy layer to retain water.
4.a)Habitats include small ponds and shallow areas of lakes and rivers. Sacred Lotus is native to southern and eastern areas of Asia.
b)Camels live in deserts, where it is hot and dry. Camels have adapted and found ways to help them survive in deserts. They have a thick coat of hair that protects them from the heat in the day, and keeps them warm at night. Their large feet spreads their weight on the sand when they are walking.
