The fundamental and functioning unit of genetics is called genes. They are units of DNA that produce proteins that control the characteristics of organisms.
<h3>What is the role of genes?</h3>
Genes are the basic and fundamental of inheritance and are made up of deoxyribonucleic acid. The variation of the gene of the same trait forms the alleles.
They code for the proteins that produce protein or RNA structures. Genes are located on the chromosome structure and code for proteins that play an important function and role in cell activity.
Therefore, option D. genes are a section of DNA that codes for proteins is correct.

The correct answer to the question is releasing waste and decomposition. In the nitrogen cycle, once a consumer gains nitrogen nutrients from animals or plants, it recycles these nutrients back to the earth by releasing waste and decomposition.
The cell you are examining under the microscope appears to contain a nucleus. This organism belongs to the domain <u>Eukarya</u>.
- The only domain that includes multicellular, visible organisms including humans, animals, plants, and trees is eukaryote.
- Numerous microorganisms, including fungi, algae, and micro-animals, also call it home. Since fungi are so diverse, two distinct fungi may have genetic differences comparable to those between a person and a fish.
- Eukarya are eukaryotes, which have organelles and nuclei that are bound to membranes. Prokaryotes are older, less numerous, and simpler than eukaryotes.
- Eukarya refers to creatures with nuclei in their cells. Additionally, it is the only realm in which multicellular observable organisms, such as people, animals, plants, and trees, exist. Achaea and bacteria are unicellular organisms without nuclei.

It has been estimated that ‘slash and burn’ agriculture is
used by up to 500 million people worldwide. The term describes the practice of
cutting and/or burning of natural vegetation for conversion into agricultural
fields. Besides the disastrous implications for forest ecosystems, the practice
can impact the atmosphere in two main ways if burning is implemented. Firstly
by causing air pollution from the smoke, and secondly by increasing carbon
dioxide in the atmosphere, which is a greenhouse gas and a driver of climate
change. Living trees also remove carbon dioxide from the atmosphere during
photosynthesis, and the process of ‘slash and burn’ effectively removes their
carbon capturing contributions to ameliorating climate change.
A.) Veins in the pulmonary circuit carry oxygen-rich blood
red blood cells are used to circulate oxygen through out the body, thus it is true.
