Explanation:
Homozygous dominant means that the plant has two alleles of the same dominant trait, in this case, round. Heterozygous plant means it has two different alleles, one round and one wrinkled. If you put them in a punnett square, you get two heterozygous and two homozygous dominant. All of them will get you a round pea plant since they all have the dominant trait in them. I can show you the punnett square I made.

Answer:</h2>
The four heart valves are the tricuspid valve, the pulmonary valve, the bicuspid valve and the aortic valve: the first two are located in the right heart, the last two in the left heart.
During the filling phase of the left atrium, the bicuspid valve is closed. It then subsequently opens and the blood passes into the left ventricle while the aortic valve is closed: this then opens and the blood flows in the aorta. the blood returns to the heart via the cavus veins in the right atrium which fills while the tricuspid is closed. Then it opens and the blood goes into the right ventricle while the pulmonary is still closed which then opens subsequently to allow blood to flow into the pulmonary arteries

Answer:
The correct answer is : sustainable use
Explanation:
- Sustainable use: The judicious and economical use of natural resources by the present generation such that the resources can be preserved for use by the successive generations is known as the Sustainable Use of Resources.
- Resource Selection : When a species selects a specific resource as the source of food or energy or shelter from among multiple available sources, the phenomenon is called Resource Selection.
- Biotic preservation : The protection of biotic organisms (plants, animals, micro-organisms) by in-situ ( in the habitat of the species) or ex-situ (outside the habitat of the species) conservation in national parks, sanctuaries and biosphere reserves to prevent them from becoming endangered or extinct due to natural disaster or human intervention.
- Biogeochemial cycling : The nutrient cycles operating on the earth, like nitrogen, carbon, oxygen, sulphur, phosphorus and water cycles, and their interaction with each other and the organisms living on earth constitute the Biogeochemical cycle.
