Explanation:
body temperature and hormone levels. give two examples from the reading of how living things respond to changes in their environment. sweating on a hot day and squinting at the sunlight. ... reproduction, based on genetic code (DNA), grow and develop, obtain and use materials and energy, respond to environment, organized.
The Earth can be divided into one of two ways – mechanically or chemically. Mechanically – or rheologically, meaning the study of liquid states – it can be divided into the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core. But chemically, which is the more popular of the two, it can be divided into the crust, the mantle (which can be subdivided into the upper and lower mantle), and the core – which can also be subdivided into the outer core, and inner core
<span>The answer is </span><span>C. haploid, and are made when haploid spores undergo mitosis. </span><span>
Pollen grains are male gametophytes in plants. In pollen sacs of an anther, spore mother cells, which is diploid, undergo meiosis and form four haploid spores. These haploid spores undergo mitosis and form haploid pollen grains.
Through the process of elimination:
- Pollen grains are haploid, so choices A. and C. are eliminated.
- In ovules, female gametes are produced, not male gametes, so, choice D. is also eliminated.</span>
Although the influence of climate change on desertification has not been fully understood yet, according to GreenFacts, it is known that higher temperatures resulting from increased carbon dioxide levels can have a negative impact through increased loss of water from soil and reduced rainfall in drylands<span>. At the same time desertification contributes to climate change by releasing to the atmosphere carbon stored in dryland vegetation and soils.
