Answer:
Respiratory bronchiole
Explanation:
The respiratory bronchioles represent the narrowest airways within the lung, being continuations of terminal bronchioles that have approx. 0.5 mm in size. The epithelium of the respiratory bronchiole is composed of cuboidal ciliated cells and a small number of non-ciliated (secretory) Clara cells. The respiratory bronchioles lead into alveolar ducts composed of smooth muscle and connective tissue (i.e., elastin and collagen), connecting the respiratory bronchioles to the alveolar sacs.
An actin-binding protein called cofilin binds preferentially to ADP-containing actin filaments rather than ATP-containing actin filaments. Based on this preference, which is true? Question 7 options: Cofilin binds to the plus ends of treadmilling actin filaments. Cofilin competes with profilin for binding to actin. Cofilin binds to older actin filaments. Cofilin binds to the plus ends of actin filaments.
Answer:
Cofilin binds to older actin filaments
Explanation:
Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.

Explain the process of finding the volume of irregular solid in laboratory with diagram
Answer:
If the object has an irregular shape , the volume can be measured using a displacement can . The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the spout. As the irregular object is lowered into the displacement can, the water level rises.

How do the outer layers of cells on the underside of a leaf work to gather carbon dioxide?
The outer layers of cells on the underside of a leaf work to gather carbon dioxide by the utilization of stomata.
What are Stomata?Stomata may be defined as the presence of tiny pores in the epidermis of the leaf or stem of the plant. The fundamental function of this structure is to regulate the amount of gas exchange.
A massive amount of gaseous exchange takes place in the leaves through these pores for the purpose of photosynthesis.
The opening and closing of these stomata are regulated by the guard cells. In order to prevent water loss through such pores, plants are required to close such pores during mid-day.
Therefore, the outer layers of cells on the underside of a leaf work to gather carbon dioxide by the utilization of stomata.

what type of transport takes place when a protien allows an ion to enter a cell, but no additional energy is needed to make this happen?
Answer:
The answer is facilitated diffusion. It requires no energy because the ions are traveling down the concentration gradient. Facilitated diffusion is important for the regulation of ions in a cell. It also enables ions to pass across the hydrophobic layer of the cell membrane composed of phospholipids.

use numbers to arrange the events of a demographic transition in order in which they occur
is this correct?
(DTM) is defined by a country's death rate dropping quickly while its birth rate staying high. Because of this, a nation in Stage 2 will show an increase in its general population—not because the birth rate is rising, but because births outnumber deaths.
What are the different events of a demographic transition?The demographic transition model was initially proposed in 1929 by demographer Warren Thompson. The four stages of the paradigm are pre-industrial, urbanizing and industrializing, mature and post-industrial.
Stage 1: Slow population growth is caused by high birth and mortality rates. Stage 2: While the birth rate stays high and the death rate declines, population growth accelerates. Stage 3: Population growth slows as the birth rate starts to decline.
Therefore, 1,4,2 and 3. It is correct events of a demographic transition in the order in which they occur.

High-latitude ocean water tends to support large planktonic communities because ________. of higher dissolved carbon dioxide there are fewer predators that feed on plankton there is abundant light of the longer summer day length of higher dissolved oxygen and nutrient concentrations
Answer: They tend to support large planktonic
communities because (of higher dissolved oxygen and nutrient concentrations).
Explanation:
Planktonic communities are made up of basic organisms that forms the oceanic food web. They are broadly divided into Phytoplankton (these are the producers), Zooplankton (these are the consumers) and Bacterioplankton (these are the recyclers).
High-latitude ocean water is mostly affected by the quantity of oxygen and nutrients it contains. Large planktonic communities thrives in these aquatic environment because is contains higher amount of dissolved oxygen and nutrient concentrations which forms part of their basic needs for survival. This is so because changes in ocean water can impact all levels of the food web. Increase or decrease in ocean temperature can modify the plankton diversity and distribution directly by altering it's metabolic rates and growth.
Therefore due to the geographic location of high latitude ocean, higher dissolved oxygen and nutrient concentrations favour the survival of a larger planktonic communities than other ocean parts.

define uniform and non-uniform velocity. How much acceleration is produced on an object at uniform motion, why? Pls answer my question anyone pls!
Answer:
when a body covers equal distance in equal interval of time with a known direction, small the interval may be then velocity is said to be uniform velocity.
when an object covers unequal distance in a specified direction is said to be non-uniform velocity.
It produce zero acceleration as acceleration is defined as the rate of change of velocity per unit time. So, if the body exhibit uniform velocity,then the rate of change of velocity (dv=0) will be zero.
