Answer:
One building block
Explanation:
The prefix mono means one
<span>It may be difficult for ecologists to determine the size of a bird population if that population migrates to different locations throughout the year. During migration, some birds may split off from the group and not return, others may die, and still others may join. Therefore, the bird population will be in constant flux. It is hard to know, when the birds return to their prior location, if the population consists of the same group of birds (in addition to deaths and births) or whether it has grown or shrank through other means. However, to estimate the size, an ecologist can track a migratory flock through several years, counting each year to get a general sense of the population size. Additionally, given one measurement, an ecologist could consider the average lifespan and birth rates of the population to extrapolate the size of the population in subsequent years.</span>
Answer:
Hey there!
The correct answer would be "derived from fish, beans, milk, and eggs" and "held together by peptide bonds"
Let me know if this helps :)
Answer:
systematics is the correct answer.
Explanation:
- The modern approach to classification, with the broader goal of reconstructing the evolutionary history, or phylogeny, of organisms is: systematics.
- Systematics plays an important role in the field of biology.
- Carl Linnæus is the father of Systematics.
- Systematics refers to the study of the diversification,nomenclature, and classification of the living organism in the past and also in present.
- Systematics is used to understand the evolutionary relationship and the purpose of systematics is to describe and explain biological variety.
- The main objective of systematics is to identify species and to give scientific names to organisms, it used to determine the arrangement of the living organism and to study the evolutionary history of organisms.
Answer: Glial cells called ASTROCYTES help maintain the blood-brain barrier, whereas SCHWANN CELLS create the myelin that envelopes axons
Explanation: Glial cells are specialized cell that are found in both central and peripheral nervous systems, that surrounds the neurones, providing them with support and insulation. There are different types of Glial cells these includes:
- Astrocytes: they maintain the blood brain barrier.
- Schwann cells: create the myelin that envelopes axons of the peripheral nervous system neurones.
- satellite cells: These cells help regulate the external chemical environment of neurones.
- Microglia: they clean up cellular debris through phagocytosis.
- Oligodendrocytes: create the myelin that envelopes axons of the central nervous system
