Answer:
Organisms better adapted to the environment
Explanation:
According to the evolutionary theory proposed by Charles Darwin in "The Origin of Species" (1859), the fittest organisms are those that are better suited to the environment (i.e., have a higher fitness). These organisms have more chances to survive and reproduce, and thereby they have also more chances to leave their genes in the next generation. This process is the central concept of evolution, and it is called natural selection. In consequence, evolution produces phenotypic changes or 'adaptations' that are inherited by organisms over generations, and certain traits are lost during this process.
Answer:DNA found in older primate fossils resemble those of humans today
Explanation:
Answer:
Male cones produce microspores.
Pollen grain contains cells that develop into sperm.
Explanation:
Gymnosperms are seed-bearing vascular plants. They produce cones and seeds to carry their reproductive structure. They produce both types of cones (male and female) for fertilization by making gametes. Male cones produce microspores to make pollen grains. Female cones give rise megaspores which produce ovules. Pollen grains spilt up to make sperm. One of these sperms fuse with egg cells for the fertilization.
Answer:
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
