The definition of (individual) biological success is having offspring who also reproduce. In other words it's a headcount of grandchildren.

The idea is that "sewing your wild oats" is not sufficient. Your children must also be willing and able to reproduce.

The main objection I've heard to this definition is the case where you have grandchildren who fail to reproduce. Technically this is the "failure" of your children, not you.

Previous answer:

I believe it is if one has offspring that reach the age when they to are able to have viable offspring (whether or not they actually do)

Each type of tRna carries a specific amino acid at one end, and at the far-side 'presents' a triplet codon to the complementary triplet codon in the [being translated] mRna which is embedded in a specific channel in the Ribosomes. These amino acids are sequentially added to the growing, nascent protein chain.

Transfer RNA (tRNA) carries amino acids to the ribosomes, to enable the ribosomes to put this amino acid on the protein that is being synthesized as an elongating chain of amino acid residues, using the information on the mRNA to "know" which amino acid should be put on next. For each kind of amino acid, there is a specific tRNA that will recognize the amino acid and transport it to the protein that is being synthesized, and tag it on to the protein once the information on the mRNA calls for it.

Fertilization in humans occurs when a sperm cell penetrates and fertilizes an egg cell, resulting in the formation of a zygote. This typically takes place in the fallopian tube. The zygote then undergoes cell division and eventually implants itself in the uterus, leading to pregnancy.

Osmosis causes water to move across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. In plant tissues, osmosis helps maintain turgor pressure, allowing the plant to remain upright. In animal tissues, osmosis is crucial for maintaining proper hydration levels and regulating cell volume. However, excessive osmosis can lead to cell damage or bursting.

Abiotic factors such as temperature or rainfall are not density-dependent factors limiting population growth. These factors do not change in intensity depending on the size of the population.

Iguanas are native to Central and South America, as well as some islands in the Caribbean. They typically inhabit tropical environments such as forests, deserts, and coastal areas. In some places, iguanas have been introduced as exotic pets and have established feral populations.

Temperature has a significant impact on the rate of diastase reaction. As temperature increases, the rate of reaction also increases due to higher kinetic energy of the molecules involved. However, there is an optimal temperature range for diastase activity, beyond which the enzyme can become denatured and less effective.

Advantage:

·Only need one member of species to procreate

Disadvantage:

·Since they are pretty much clones they have the same immunity, diseases that kill one will likely kill them all

Have a nice day :)

The cell membrane is selectively premeable. It regulates what comes and goes from the cell.

Homeostasis- The ability of living things to maintain steady state of operation the membrane helps in this activity.

The starting molecule for the Krebs cycle is acetyl-CoA, which enters the cycle by combining with oxaloacetate to form citrate.

RNA is required during protein synthesis because it serves as the intermediary between DNA, where genetic information is stored, and proteins, which perform cellular functions. Messenger RNA (mRNA) carries the genetic code from DNA to ribosomes, where proteins are synthesized. Transfer RNA (tRNA) and ribosomal RNA (rRNA) also play essential roles in facilitating protein synthesis.

Muscle cells are specialized for movement due to their ability to contract and generate force. They are elongated and contain many contractile proteins that allow them to produce the mechanical force needed for movement.

Yes, plants are a great source of food for both humans and other animals. They provide essential nutrients like vitamins, minerals, and fiber that are important for overall health. Additionally, plant-based diets are associated with various health benefits and are more sustainable for the environment compared to animal-based diets.

Lipid-soluble hormones are able to penetrate through the cell membrane and bind to receptors located inside the cell. Such hormones diffuse across the plasma membrane and target those receptor cells found within the cytoplasm. Lipid-soluble hormones target the cytoplasmic receptors which readily diffuse into the nucleus and act on the DNA, inhibiting and stimulating certain proteins. lipid-insoluble are unable to penetrate through the plasma membrane and function with their target cells in a much different and complex manner. Lipid-insoluble hormones must bind with cell-surface receptors which follow a different path involving a second messenger. The hormone's inability to penetrate the membrane requires a second messenger which translates the outer message and functions within the cell.

The starting substance of the Krebs Cycle is acetyl-CoA, which is formed from the breakdown of carbohydrates, fats, and proteins in the form of pyruvate.

Pasteurisation is a procedure developed by Louis Pateur in order to destroy microorganisms by employing 60 degree celsius for a period of 1-2 minutes. The main aim of the procedure is not to kill all the microorganism but to curtail the growth and maintain it at a particular level. It is more a static procedure than a cidal procedure.

yes and no. they are pathogenic because they harm and they arent pathogenic because they dont always harm and instead sometimes provide benefit to the host

The process responsible for moving water into a cell is called osmosis. Osmosis is the movement of water molecules from an area of higher water concentration to an area of lower water concentration across a selectively permeable membrane.

Organisms need oxygen, glucose, and mitochondria to carry out aerobic cell respiration. Oxygen is the final electron acceptor in the electron transport chain, glucose is the source of carbon and energy, and mitochondria are the organelles where aerobic respiration takes place.

Sugar cane is harvested and then crushed to extract the juice. The juice is clarified, filtered, and boiled to concentrate it into syrup. Through a series of evaporation, crystallization, and centrifugation steps, the sugar crystals are separated from the syrup, dried, and packaged as raw sugar.

The site of ribosome synthesis is in the nucleolus of eukaryotic cells. The nucleolus is a specialized region within the cell nucleus where ribosomal RNA (rRNA) is transcribed and ribosomal subunits are assembled before being exported to the cytoplasm for final maturation.

The structure that holds two strands of DNA together after replication until metaphase of mitosis is the centromere. The centromere is a region of the chromosome where the two sister chromatids are held together and is essential for proper chromosomal segregation during cell division.

These organisms are called producers. They are the first group in the food chain, and they are also the base of life since without photosynthesis ( the process of manufacturing sugar molecules using energy from the sun) life wouldn't exist as we know it.

In prophase, there are 46 chromosomes present, which are duplicated sister chromatids. In metaphase, there are still 46 chromosomes, but they are aligned along the metaphase plate. In telophase, the chromosomes have separated and there are once again 46 individual chromosomes in each daughter cell.
