Answer: Unicellular and microscopic features set the protista apart from the rest of the kingdom.
Explanation:
Protista are eukaryotic organisms that are neither plants, animals or fungi. They do not have a natural group with whom they share common ancestor. They have a unique features that set them apart from the rest of the kingdom which are unicellular and microscopic. Examples are amoeba, blue green algae, diatoms, green algae, ciliates and many more.
Answer:
B) how changes in development underpin the evolution of morphology.
Explanation:
Evolutionary developmental biology is the new field of research in biology which studies the combined relationship of the evolution and the developmental processes.
This interdisciplinary study compares the developmental biology in terms of evolution or in a way that how the developmental biology process evolved in the organism on the basis of studying the phenotypic features of the organisms.
Thus, Option-B is the correct answer.
The middle stone age and the later stone age corresponds to the middle and the late pleistocene.
Cultural evolution during the middle and the late pleistocene :-
In southwestern Asia as well as northern and southern Africa, personal ornaments in the form of perforated seashells are recorded from the early Late Pleistocene. In the Old World, Neanderthals and anatomically modern humans are linked to a range of personal ornamentation by about 40,000 years ago (Ka). These include fully created ornaments as well as organically modified things. The appearance of figurative art, mythical imagery, and other types of items, like as musical instruments, at various times in history suggest that completely modern behavior began to emerge more gradually towards the middle of the Late Pleistocene and most definitely no later than 40 Ka. Many, but not all, of the lengthy and rigorous history of study might well have helped to the relevant data come from Europe.

Answer: look at the screenshot
Answer:
with haploid or diploid set of chromosomes. True
Explanation:
There are two types of cells in the body, haploid cells and diploid cells. The biggest difference is related to the number of chromosomes that each cell contains, while diploid cells contain two chromosomes (2n), haploid cells contain a chromosome (1n).
Features:
1. A haploid cell has only one set of chromosomes (n), while diploid cells have two sets of chromosomes (2n).
2. In humans, somatic cells are diploid, while gametes are haploid.
3. Diploid cells develop as a result of mitotic cell division, while haploid cells develop as a result of meiotic cell division.
4. Mitosis produces 2 identical daughter cells, where both stem and daughter cells are diploid. In meiosis, a diploid cell divides twice to produce 4 haploid daughter cells.
5. Humans and most animals are considered diploid organisms, while algae and fungi are examples of organisms that are haploid in most of their lives. Male bees, wasps and ants are also haploid.
