Answer:
New cells produced within uterus (or any other organ) as a direct result of mitotic cell division.
Mitosis is the type of cell division which results in the formation of two daughter cells with same number of chromosomes as that of parent cell. It plays an important role in growth and repair of cells and tissues in multi-cellular organisms such as human beings.
For example, mitotic division helps in formation and repair of uterus lining lost during menstrual phase. Similarly, it keeps replacing the dead skin cells lost from our body surface on regular basis.
Meiotic division on other hand is used only in the formation of haploid gametes i.e. sperm in males and egg in females.
b. Gate
c. Nucleus
d. Membrane
Answer:
The correct answer is B) 2.
Explanation:
A molecule of water (H₂O) has two bonds, one between each hydrogen atom (H) and the oxygen atom (O). Therefore, if we have 1 mole of water, it will contain 2 moles of bonds.
The frog's vestigial thumb may provide some vestigial functions like clinging or handling prey. Like opposable thumbs in primates, it's a remnant from evolution, and may aid in survival-oriented activities or serve no current significant purpose.
The frog's vestigial thumb, much like opposable thumbs in primates, is believed to be a trait left over from previous evolutionary stages. While its function in frogs is not fully understood, it is suggested that vestigial structures like the thematic thumb could still retain some functional or minimal purpose, potentially related to clinging or handling prey. For example, in primates, the opposable thumbs and toes are an adaptive trait providing the ability to effectively grasp branches, cling onto surfaces, and hold objects which contributes vastly to their survival in arboreal environments.
Although in frogs the thumb likely doesn't grant the same mobility or dexterity as in primates, its presence may still aid in activities like feeding, movement, or escaping from predators. Also, it's important to note that not all traits are formed for survival or adaptive purposes and could be neutral or nonadaptive, serving no current significant function or benefit.
