<h2>Angiosperms </h2>
Explanation:
Angiosperms are the most diverse group of plants, some statements which reflect angiosperm adaptations to life on land:
- Flowers attract animal pollinators carrying pollen from other plants of the same species
- Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits
- In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators
- Floral parts of the sporophyte protect the reduced female gametophyte from drying out and from UV radiation
- Seeds protect and nourish plant embryos, and fruits protect the seeds
- Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals
Every organism’s DNA will not look and act the exact same way. If the parent reproduces asexually is the only exception to that rule. However, if all organism’s DNA resembled and acted as a deer’s DNA, then all organisms would be deer. Therefore, there are genetic differences that separate species and ensure different behaviors from organism to organism. While the DNA will be similar by using the same four nucleic bases, there is an entirely different combination of those bases from organism to organism.
A virus is a microscopic parasite that infects cells in biological organisms, they reproduce only by invading and controlling other cells as they lack the cellular machinery for self reproduction. Additionally, viruses contain at least one unique protein synthesized by specific genes in the nucleic acid, the proteins forms a shell called capsid around the nuclei acid.
The period of time that begins with the contraction of the atria and ends with ventricular relaxation is known as the Cardiac cycle.
<h3>What is a cardiac cycle?</h3>
The cardiac cycle describes a whole heartbeat from its onset to the beginning of the following pulse. It consists of the diastole, systole, and the interval in between. Heart rate, which is naturally expressed as beats per minute, serves as an example of how a cardiac cycle occurs.
<h3>Cardiac Cycle Physiology</h3>
The left and right halves of the human heart's four chambers make up the body. The right and left ventricles are located in the lower two chambers, while the left and right atria are located in the two top chambers. Pumping deoxygenated blood to the lungs through the pulmonary arteries and the pulmonary trunk is the right ventricle's main job. While the left ventricle is in charge of pushing freshly oxygenated blood to the body through the aorta.
