Answer:

tumor suppressor gene

Explanation:

A tumor suppressor gene is capable of modulating cellular processes during cell division and/or replication, thereby avoiding uncontrolled cell proliferation and tumor development. For example, the p53 gene is a tumor suppressor gene that encodes a protein (p53) which is well known to regulate critical cellular processes such as, for example, cell cycle arrest and programmed cell death (apoptosis). Moreover, breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes that regulate the repair of damaged DNA through the Homologous recombination (HR) pathway. In consequence, mutations in BRCA1 and BRCA2 genes can increase the risk of developing breast cancer.

How can mutations lead to human evolution?
lions [1.4K]

Answer:

How Mutations Can Lead to Human Evolution?

Explanation:

A mutation is the random change in the nucleotide sequence or in the DNA organization (genotype) of a living being, [1] that produces a variation in its characteristics and that is not necessarily transmitted to the offspring. It occurs spontaneously and suddenly or due to the action of mutagens. This change will be present in a small proportion of the population (variant) or the organism (mutation). The genetic unit capable of mutating is the gene, the unit of hereditary information that is part of DNA.

In multicellular beings, mutations can only be inherited when they affect reproductive cells. A consequence of mutations can be, for example, a genetic disease. However, although they may seem harmful in the short term, mutations are essential to our long-term existence. Without mutation there would be no change, and without change life could not evolve.

Where does the energy go after it reaches the top predators?
mihalych1998 [28]

Answer:

Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.

A gardener is experimenting with one of her African violet plants. This plant produces large, deeply colored flowers. She shows
Lady bird [3.3K]

Answer:

The offspring with large, deeply colored flowers is produced from vegetative reproduction which the offspring with small, lightly colored flowers is produced from sexual reproduction.

Explanation:

Reproduction of a plant is the propagation of that plant and it occurs via the sexual or asexual means. The asexual means also called vegetative reproduction involves only one parents and the resulting offspring grows from a part of this parent. Sexual reproduction involves the union of sex cells from two parents (male and female).

In asexual or vegetative reproduction, the offsprings are genetically identical to the parent they emanate from while in sexual reproduction, the offsprings can be genetically different due to the process of recombination that occurs in gametes during their formation (meiosis). This allows for genetic variation among the offsprings.

Therefore, the offspring that resembles the parent i.e. large and deeply colored was likely produced by the vegetative or asexual means of reproduction while the offspring that exhibited a different characteristics from the parent was produced from sexual reproduction.
