<span>In the sentence "Biologists recognize the following levels of cell organization: _____, the choice that correctly completes the sentence is b. cellular, tissue, organ, system, and organism. A cell is the basic unit of living organisms. The group of similar cells that work together to perform a specific job is a tissue. The group of multiple tissues joined together in the functional structure is an organ. Functionally related organs form organ systems, which all together form one organism.</span>
Answer:
The correct answer is 6 genotypes
Explanation:
The most known case is two alleles of one gene (A and a), and we know the possible genotypes formed are three: AA, Aa, aa. Therefore, for a given number of alleles n, we calculate the number of possible genotypes as the sum of integers between 1 and n.
- For 2 alleles (n=2, the sum of integers between 1 and 2): Genotypes= 1 + 2= 3
⇒ For 3 alleles (n=3, the sum of integers between 1 and 3): Genotypes= 1 + 2 + 3= 6
So, we have 6 genotypes for 3 alleles (W1, W2 and W3) and they are:
W1W1
W1W2
W1W3
W2W2
W2W3
W3W3
Answer;
C) xylem and phloem
Explanation;
-Both Xylem and phloem are referred to as vascular tissue, they play an important role in higher plants, which is mainly transportation of materials through out them. They allow inter-cellular communication through transportation of substances in higher plants.
-Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant .Phloem is responsible for the transport of sugars from source tissues (photosynthetic leaves) to other tissues of the plant (non-photosynthetic).
Goblet cells are those secretory cells or unicellular glands, which make and expel mucus can be found in simple columnar and pseudostratified columnar epithelia.
<h3>What are goblet cells? </h3>
They are goblet-shaped cells that have a basal nucleus and a cytoplasm loaded with mucins (the main component of mucus).
<h3>Characteristics of goblet cells</h3>
- It is present in the epithelia of the respiratory and digestive systems.
- Its main function is to secrete mucus, which protects and lubricates the inner surface of simple columnar and pseudostratified columnar epithelia.
Therefore, we can conclude that goblet cells are mucus-secreting cells present in epithelial linings.
