Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.
Hopefully this helps you! Have a great day!

Over time, the toxins from inhaled cigarette smoke break the thin walls of alveoli, leaving larger, less efficient air sacs. The sacs also begin to lose their bounce, making it harder to bring in the oxygen and expel carbon dioxide. 3 Both can become partially trapped in the lungs.
Biodiversity completely depends on the ecosystem. The <u>increase in biodiversity also leads to an increase in ecosystem stability.
</u>
<u>
</u>
Further Explanation:
Biodiversity is the term used for <u>describing the variety of species found on earth.</u> It can be animals, plants, microorganisms (bacteria and fungi), etc. the earth is rich in biodiversity; there are so many species that have to be discovered, whereas there are several species that have extinct. The entire living organism forms the ecosystem. It also includes <u>their physical environment and the interpersonal relationship with them.
</u>
<u>
</u>
<u>Species play a crucial role in the ecosystem.</u> So the extinction or loss of particular species affects the perfect balance of the ecosystem. The <u>ecosystem work in a cycle that means plants absorb the energy from the sun and produce food through the process called </u><u>photosynthesis</u><u>.</u> The plant produced food is called the primary production, which is utilized by the myriad animals. The rate of <u>primary production completely depends on the global food supply.</u> It also increases the rate of climate change. The plants produce carbon dioxide at night time and remove it in the atmosphere. That decreases the variability of the environment and disturbs its original state.

Answer:
gills
Explanation: A fish without a jaw was the first vertebrate to evolve. These fish used filtration to capture their food and sucked water and debris from the sea through their mouths and then released the water and trash through their gills. Some features are as follows:
1. They have a notocorda that serves as support through the back of the fish.
2. Gill bags. These organs are responsible for filtering the oxygen in the water.
3. A pineal eye that is sensitive to light
4. A cartilaginous skeleton
Stamen is composed of anther and filament. The pistil is composed of stigma, style, and ovary. ... The key difference between stamen and pistil is that stamen is the male reproductive organ which produces pollens of angiosperms while pistil is the female reproductive organ which produces ovules of angiosperms.
I hop this helps!
