Answer:
The correct option is A) 1, 2, 3, 4, 7
Explanation:
As the walls of the cells are narrow and have microvilli, we can predict that the phenomenon of transferring materials by any means such as active transport might be occurring in the tissue.
Every tissue will have an epithelium and since the tissue has a single layer of cells only we can predict that the cells might be having a simple epithelium.
The presence of uni-layer or single cells also makes us infer that the tissue has columnar epithelium.
The presence of microvilli also suggest that secretion by exocytosis might be occurring in these tissues.
Human gametes are oogamous.
Oogamous is a form of anisogamy which best describes human gametes. Oogamous is characterized by the joining of a large, immobile egg and a small, mobile sperm for reproduction. The male gametes are extremely motile and they are usually responsible for the joining of the corresponding gametes. The wide extension of oogamy in higher animals brings about the conclusion that the high motility of the gametes makes them to perform their respective roles better than it could be performed by general isogametes
The presence of over 700 genes involved in height determination is an example of a polygenic trait.
<h3>What is a polygenic trait?</h3>
A polygenic trait refers to a trait that is determined by multiple genes rather than by only one gene. This is opposite to a monogenic trait that is determined by only one gene.
<h3>What are some examples of polygenic traits?</h3>
In humans, some examples of traits that are determined by multiple genes are:
- Height
- Hair color
- Skin color
Based on this, heigh is a polygenic trait.

Answer:
(A) True
Explanation:
The sun is producting the electromagnetic radiation which is the primary energy source on Earth and the driver of the entire climate system.
In general the sun is the source of energy that drives all life on Earth. This energy governs the weather, ocean currents and the hydrological cycles.
Without the continuous influx of sunlight and heat, life on Earth would cease to exist. The sun sets off the hydrological cycle, causing it to constantly evaporate into the atmosphere, from which it falls back to Earth.
Answer:
b. no
Explanation: It is not possible because if you draw a punnett square you see that the only phenotype you get is Cc. C (curly hair) is dominant over c (straight hair) so curly hair will always be expressed.
