Answer:
Chromosomes contain genes, which help to determine an organism's traits. Genes come in alternate forms called alleles. The actual gene combination that an organism receives from its parents is called its genotype, while the trait that gets expressed as a result is referred to as its phenotype. If an offspring receives the same type of allele for a given gene from each parent, it is said to be h o m o z y g o u s. If the alleles differ, it is h e t e r o z y g o u s.
Explanation:
Answer: b. fossil fuels are nonrenewable, so humans will run out of them eventually. burning fossil fuels also contributes to global climate change by releasing carbon dioxide into the atmosphere.
Explanation:
Fossil fuels are limited and we will run out of them eventually. They cannot be replenished in a single human's lifespan. Fossil fuels contribute to the destruction of ecosystems, but not only that. They release carbon dioxide into the atmosphere that warms the Earth. Therefore, anything other than B. would be incorrect.
<h2>Answer </h2>
- Hybridization
- Recombinant DNA
- Selective Breeding
<u>Explanation</u>
1. Cross-breeding; a method that unionizes gametes of differing genes to create a new individual is hybridization. It is the idea of combining atomic orbitals into different hybrid orbitals that is proper for the pairing of electrons to create chemical bonds in valence bond as per the atomic theory.
2. Cultured DNA molecules from different biological sources is recombinant DNA. They are the molecules are DNA molecules determining by laboratory techniques of genetic recombination to take mutually genetic material from various origins.
3. A process of breeding organisms because of their specific traits is selective breeding. It is the method that grants humans practice animal breeding and plant breeding to selectively develop selective over phenotypic traits
Answer:
the first is mostly false but somewhat tru the second is true and the third is true
Explanation:
Answer:
Alligators: Growth depends greatly on the surrounding environment, including temperature, and sexual maturity is reached at approximately 6 feet long. The life span varies greatly for these large reptiles, averaging 35 to 50 years for wild alligators and 60 to 70 years for crocodiles.
Humans:In summary, the human life cycle has six main stages: foetus, baby, child, adolescent, adult and elderly. Although we describe the human life cycle in stages, people continually and gradually change from day to day throughout all of these stages.
