Consider the following statement and mark the wrong-a)bamboo plant is ...
Explanation:
The statement marked as wrong is option 'B': "Organism exhibiting oestrous cycle do not show cyclical change in ovary, placenta and hormones". This statement is incorrect because organisms exhibiting oestrous cycle do show cyclical changes in ovary, placenta, and hormones.
Explanation for the other options:
a) Bamboo plant is monocarpic: This statement is correct. Monocarpic plants are those that flower and produce seeds only once in their lifetime, and then they die. Bamboo is an example of a monocarpic plant.
b) Organism exhibiting oestrous cycle do not show cyclical change in ovary, placenta and hormones: This statement is incorrect. Organisms exhibiting oestrous cycle do show cyclical changes in ovary, placenta, and hormones. The oestrous cycle is a reproductive cycle seen in many mammals, where the female goes through a series of physiological changes that prepare her for reproduction. These changes are regulated by hormones, including estrogen and progesterone, which are produced by the ovary.
c) All mammals are not continuous breeders; some are seasonal breeders: This statement is correct. Mammals exhibit different breeding strategies, and some are seasonal breeders, meaning they only mate and reproduce during certain times of the year. Examples of seasonal breeders include deer, elk, and bears.
d) None of the above: This option cannot be marked as the correct answer as option 'B' is incorrect.
Consider the following statement and mark the wrong-a)bamboo plant is ...
Explanation:
The given statement is about identifying the wrong statement among the options given. Let's analyze each option one by one:
a) Bamboo plant is monocarpic
- This statement is correct. Monocarpic plants are those that flower and produce fruits only once in their lifetime, and then die. Bamboo is an example of a monocarpic plant.
b) Organism exhibiting oestrous cycle not show cyclical change in ovary, placenta and hormones
- This statement is wrong. Organisms that exhibit an oestrous cycle do show cyclical changes in the ovary, placenta, and hormones. The oestrous cycle is the reproductive cycle in female mammals, characterized by the periodicity of ovulation and changes in the hormonal levels.
c) All mammals are not continuous breeders, some are seasonal breeders also
- This statement is correct. Not all mammals breed continuously throughout the year. Some species have breeding seasons or are seasonal breeders. For example, deer, bears, and foxes are seasonal breeders.
d) None of the above
- This option is not the correct answer since option 'B' is incorrect.
Therefore, the correct answer is option 'B'.
