Answer:
Autocrine = Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Juxtacrine = Juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact.
Endocrine = Endocrine signaling occurs when endocrine cells release hormones that act on distant target cells in the body. Endocrine signaling can be distinguished from two other types of signaling: neural signaling and paracrine signaling. ... Neurons are connected to their target cells via synapses.
Paracrine = Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells.
Answer:
D
Explanation:
A tectonic plate boundary, as the name intuitively suggests, is the boundary between two tectonic plates. A tectonic plate boundary can be a convergent boundary or a divergent boundary. Convergent boundaries are hotspots for earthquakes because of the occasional stress release (as energy) as the tectonic plates collide. Towns & cities close to these boundaries are highly prone to destruction by earthquakes and tsunamis.
Answer:
C
Explanation:
For standing waves, the areas where the amplitude is zero are referred to as nodes while the areas where the amplitude is at the maximum are known as antinodes.
A standing wave derives its feature primarily from the fact that there are certain points along the medium of transmission that are apparently seeing to be standing still with no displacement whatsoever. At the same time, there exist opposing points to the points of zero displacements. These points have a maximum displacement in both the positive and negative directions. While the former is referred to as nodal points, the latter is known as the antinodal points.
A nucleosome consists of DNA wrapped around the histone proteins
Answer:
The weakest part of a long developing and adolescent bone is called growth cartilage (epiphyseal plate)
Explanation:
Both children's bones and adults' bones are at risk of injury. However, in the case of bones in a child, they are subject to an injury known as a growth cartilage fracture or epiphyseal plate. These growth cartilages are areas that are in full development in the vicinity of long bones. Its function is to help establish the length and shape of the bone in the process of maturation. The growth of a long bone happens from the end next to the growth cartilage. In adulthood, these growth cartilages are strengthened forming the bone.
