Oxygen in the lungs leaves the air sacs and enters the blood veins or capillaries

Biology
1 answer:
nikklg [1K]4 years ago
3 0

Answer: Each air sac is surrounded by a network of fine blood vessels (capillaries). The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell.

In my own words

Each air sac is encircled by an organization of fine veins (vessels). The oxygen in breathed in air goes over the slim coating of the air sacs and into the veins. This is known as dissemination. The oxygen in the blood is then hefted around the body in the circulation system, arriving at each cell.

Flowers are a collection of _____ tissue produced by some plants.
Lostsunrise [7]
There are choices for this question namely:

1. Sterile
2. Reproductive
3. Both
4. Neither

The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.

go help me on my 3 question please

Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.
