Question 1: How do offspring resulting from sexual reproduction differ from offspring resulting from asexual reproduction?
Asexual reproduction involves a single parent. It results in offspring that are genetically identical to each other and to the parent. All prokaryotes and some eukaryotes reproduce this way. There are several different methods of asexual reproduction. They include binary fission, fragmentation, and budding. <u>AND</u> in in sexual reproduction, parents produce reproductive cells—called gametes—that unite to form an offspring. Gametes are haploid cells. This means they contain only half the number of chromosomes found in other cells of the organism. Gametes are produced by a type of cell division called meiosis, which is described in detail in a subsequent concept.
Question 2: How do DNA, chromosomes, and genes work as the instructions for heredity?
Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit.
Question 3: How do environmental factors and heredity affect personal health?
Heredity and environment interact to produce their effects. This means that the way genes act depends on the environment in which they act. In the same way, the effects of environment depend on the genes with which they work.
Hopes this answers your questions :)
Answer: Life on earth, in order to continue stabilization, must have ballance.
Explanation: Life on earth needs balance. Like how plants need bees and bees need plants and everything relies on the survival of these two organisms. Without bees the plants cannot fertilize other plants which means herbivores would starve due to lack of food, as well as carnivores because now their food source has diminished. Everything on earth needs one another. It does not matter whether it is a oceanic ecosystem, or a continental ecosystem. As long as each creature is there working to keep the balance, the organisms that call earth home will be able to survive a long time.
The liquid would be hypertonic towards the onion cell. This causes a net diffusion of water out from the onion cell into the surrounding liquid through osmosis. The onion cell is likely to wilt. If observed under a microscope, it is possible to view the plasma membrane pull away from the cell wall as well as a shrunken vacuole.
Objectivity: The test should be free from subjective—judgement regarding the ability, skill, knowledge, trait or potentiality to be measured and evaluated. 2. Reliability: This refers to the extent to which they obtained results are consistent or reliable.
