Answer:
The correct answer will be-
1. Evolutionary unity- DNA
2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.
Explanation:
<u>Case I
</u>
Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.
The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.
<u>Case II
</u>
The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.
Whatd did she discover?? it doesnt make sense
Answer:
It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including transporting oxygen and nutrients to the lungs and tissues
Explanation:
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
Answer:
First, we will see its body structure and collect more information about it. Second , we will see the mode of reproduction i. e. sexually or asexually.
Explanation:
We will observe structure of the body and cell. If this organism is eukaryotic and no cell wall so we can say that it belongs to kingdom animalia. We also observed its mode of reproduction i. e. sexual reproduction or asexual reproduction such as fragmentation, binary fission etc.
An antibody is also known as an immunoglobulin. It is a
glycoprotein that plays a critical role in the immune system by identifying and
destroying invading foreign particles such as viruses and microorganisms. Thereby,
antibodies protect people from disease and infection.
