Lipids are a group of organic compounds including fats, phospholipids, and steroids.
Lipids are a group of organic compounds that do not dissolve easily with water. Lipids include fats, oils, monoglycerides, diglycerides, triglycerides, phospholipids, hormones, vitamins (such as vitamins A, D, E, and K), and steroids. Lipids functions by storing energy for organisms, as chemical messengers between cells, tissues, and organs, and they also function as structural parts of cell membranes.
Answer:
The question is incomplete, the correct question is;
Which statement describes asexual reproduction, but not sexual reproduction? A) New organisms are formed only after fertiliztion. B) A single cell will not develop into a full organism. C) Daughter cells contain half the genetic material of the parent cell. D) Daughter cells contain the same genetic information as parent cells.
Answer is option D. Daughter cells contain the same genetic information as parent cells.
Explanation:
The process in which organisms creates their offspring is called reproduction and the two types of reproduction are asexual reproduction and sexual reproduction.
In asexual reproduction, the offspring are produced from a single parent. They are genetically identical to each other and to the parent. Binary fission, fragmentation, and budding are the different methods of asexual reproduction. Examples of organisms which reproduce through asexual reproduction include bacteria, yeast, amoeba, hydra etc.
In sexual reproduction, the offspring are created by two parents and they are genetically unique. The gametes are reproductive cells present in the parents, produced by meiosis. They are haploid cells containing only half the number of chromosomes. The process in which the gametes from two parents combine to form a zygote (fertilized diploid cell) is called fertilization, where the zygote has twice the number of chromosomes. The zygote develops into a fully formed organism, which has a unique combination of characteristics inherited from both parents.

Explanation:
Biogeochemical cycles are pathways by which nutrients flow between the abiotic and abiotic compartments of the Earth. The abiotic portion of the Earth includes the lithosphere (the geological component of the Earth) and the hydrosphere (the Earth’s water).
Ecosystems rely on biogeochemical cycles. Many of the nutrients that living things depend on, such as carbon, nitrogen, and phosphorous are in constant circulation.
Essential elements are often stored in reservoirs, where they can be taken out of circulation for years. For example, coal is a reservoir for carbon.
Humans can affect biogeochemical cycles. Humans extract carbon and nitrogen from the geosphere and use them for energy and fertilizer. This has increased the amount of these elements in circulation, which has detrimental effects on ecosystems.
Answer:
brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different. Parents pass one of their two copies of each of their genes to their kids.
