The letter is B because i just took the test :)
B. several distantly related species develop similarities.
C. a species evolves at a slow, steady pace.
D. a species has periods of little evolution interrupted by periods of rapid evolution.
Answer: The correct answer is-
C. a species evolves at a slow, steady pace.
Gradualism can be describesd as a pattern/ theory of evolution by which already existing species give rise to new species by means of slow/ gradual and steady changes instead of major and abrupt changes.
Over long period of time, the small changes (that are beneficial for their survival) result in new species.
Example- Tiger that is evolved pattern of stripes ( which give them better advantage to hide in tall grass).
Thus, option C) a species evolves at a slow, steady pace. is the right answer.

dermal and vascular tissue
ground and dermal tissue
parenchyma and ground tissue
Vascular and parenchyma tissue carry out transpiration (option A)
Transpiration is the process of water loss from plants. It occurs through the stomata, which are small openings in the leaves. The water vapor that is lost through the stomata is replaced by water that is drawn up from the roots through the xylem. The xylem is a vascular tissue that transports water and minerals from the roots to the leaves.
Parenchyma tissue is a ground tissue that is found in all plant organs. It is composed of living cells that have thin cell walls and are often filled with air or water. Parenchyma cells in the leaves help to support the stomata and to regulate the opening and closing of the stomata.

Answer:
It can be best explained with the help of Gause's law of competitive exclusion.
It states that no two species can coexist stably which compete for exact same resources.
In such conditions, the species which is inferior to other in terms of adaptations either extinct or evolve towards a different ecological niche.
For example, Galapagos island finches evolved with different shapes and sizes of beaks as an adaptation towards limited resources available such as different types of seeds or food.
c. altostratus clouds.
b. altocumulus clouds.
d. cumulonimbus clouds.
D) Cumulonimbus clouds
Cumulonimbus clouds is known to be a dense, lowering vertical cloud that usually formed from water vapor that is carried by powerful upward air currents. Furthermore, this type of cloud is observed during a storms and can be referred to as thunderheads. Thus, cumulonimbus cloud usually forms alone in clusters and are capable of producing lightening and other dangerous severe weather such as tornadoes.
The correct answer is option D, cumulonimbus clouds
Reason -
Cumulonimbus clouds develops vertically and are referred to as unfair weather cumulus. They are formed when warm and moist air rises in the upward direction where it eventually cools and condenses into a Cumulonimbus clouds. As the condensation takes place, the air inside the cloud gets warmer than the air surrounding it. Due to this the air becomes unstable and the cloud keeps on growing vertically. As the cloud precipitates it bring hail, thunder storm and lightning.
(1) mitosis of sex cells
(2) mitosis of body cells
(3) meiosis of sex cells
(4) meiosis of body cells
Answer: The correct answer is-
(2) mitosis of body cells.
Mitosis is a type of cell division in which a parent cell produces two daughter cells having same number of chromosomes as that of their parent cell.
It occurs through a series of 5 stages that are- Prophase, metaphase, anaphase, telophase, and cytokinesis.
It is responsible for the growth of organisms and the repair of damaged tissues (in case of multicellular organisms) as new, identical cells (that are identical to each other) are produced from the parent cell.
Thus, option 2) is the right answer.
Answer:
2) mitosis of body cells
