Due to physical constraints, maximizing one life history trait (e. g. height) often comes at the expense of another (e. g. longevity); the allocation between such desirable but incompatible traits is known as:a) life history
b) growth and development
c) trade offs
d) all of the above

The correct answer is - option C.

Explanation:

Trade off is the allocation in which one trait or character is only achieve by the expense of the other character and traits of life history due to some type of natural phenomenon.

The example of such trade off is given in the question where one of the life history trait such as height come at stake of longevity, due to physical constraints.

Thus, the correct answer is - option C.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
