1) C. Gymnosperms are mostly adapted for wind pollination; angiosperms are mostly adapted for animal pollination. This is the best answer, because the others had the two types reversed. Gymnos have "naked" seeded cones, whereas Angios have seeds protected by fruit. Therefore the Angios relies on animals to eat the fruit and to pollinate, whereas Gymnos relied on wind to pollinate the ground. Gymnos came first on Earth and Angios developed later.
2) C. Cuticle. This is a waxy coating helping to keep water in. The main water losses are via stomata.
3) C. Stomata
4) B. Nonvascular
5) B. Gravity
These answers were explained in the questions that I just answered before. So refer to those for explanations.
The statements that correspond to cellular respiration are:
2) CO2 diffuses passively out of the cell.
6) O2 is pumped in and forces CO2 out
Cellular respiration in animals produces carbon dioxide as waste products. Cellular respiration is presented like this:
oxygen + glucose → energy + carbon dioxide + water
Answer:
After 3 half lives 12.5 g of C-14 left
Explanation:
Given data:
Mass of C-14 = 100 g
After 3 half lives mass left = ?
Solution:
At time zero = 100 g
At first half life = 100 g/2 = 50 g
At second half life = 50 g/ 2 = 25 g
At third half life = 25 g/2 = 12.5 g
Thus, after 3 half lives 12.5 g of C-14 left.
<span>The spindle fibers continue to shorten and move towards opposite ends or poles of the cell. This causes the cell to elongate. The chromosomes during anaphase usually have a distinct V shape. There are also two distinct sets of chromosomes now, and each daughter cell will get one set.</span>
