Living organisms such as trees'animals, and humans grow by the year
Non living organisms do not grow at all.

Natural explanation helps to explain why some life forms survive and some do not, and this links to the theory of evolution because the traits favored in natural selection become more dominant until the organism's entire population has evolved to incorporate that change.
The parts of the heart are the atria, ventricles, septum, valves. The atria collects oxygenated blood that has returned from the lungs.The ventricles , receive blood from the atria. The septum it separates the left atrium and ventricle from the right atrium and ventricle. Finally, the valves<span> separate the various parts of the heart from one another. They allow blood into places it’s supposed to be and keep it out of places it’s not supposed to be.
Undoubtedly, there are more parts of the heart but these are the main functions.

The 117th Christmas Bird Count is now over. As usual in January, I will discuss the highlights of some of the Maine counts. These standardized censuses provide an important tool to monitor the abundance of winter birds throughout North America and beyond.
I’ll concentrate on changes in regularly wintering birds, the arrival of unpredictable invaders and records of lingering birds whose wintering areas are well to our south. A rarity or two may pop up as well.
We’ll start with the southern Maine coast. The York County count was held on Dec. 21. Thirty observers found 82 species of birds.
Answer: B. Vacuoles, cell membrane, nucleus, mitochondria
Explanation:
Cell walls only belong to plants, and chloroplasts also only belong to plants. Besides that everything else belongs to both, and that means that B is the only right answer. And I have a advise for you If they ask you a question like something like this In both plant and animal cells, the need to produce energy is carried out by the function of the: the answer is mitochondria
Hope it helps
