Explain in your own words the difference between a leading strand and a lagging strand.
Answer:
So basically the primary distinction between the leading and lagging strands is that the leading strand is the DNA strand that develops continuously during DNA replication, whereas the lagging strand is the DNA strand that grows in small pieces known as Okazaki fragments. A leading strand is one that is produced in the 5'-3' direction, whereas a lagging strand is one that is formed in the 3'-5' direction. The leading strand is constantly produced where the other is not.

the lysis of red blood cells in blood agar is indicative of the presence of which enzymes?
cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi. Another cause is intense physical exercise. Hemolysins damage the red blood cell's cytoplasmic membrane, causing lysis and eventually cell death.
Explanation: One cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi. Another cause is intense physical exercise. Hemolysins damage the red blood cell's cytoplasmic membrane, causing lysis and eventually cell death.
BAP assesses an organism's ability to produce hemolysins, enzymes that damage/lyse red blood cells (erythrocytes). The degree of hemolysis caused by these hemolysins aids in the identification of members of the genera Staphylococcus, Streptococcus, and Enterococcus.
What hemolytic pattern does S aureus shows on BAP?On blood agar plates, colonies of Staphylococcus aureus are often encircled by zones of clear beta-hemolysis. The golden appearance of colonies of some strains is the etymological root of the bacteria's name; aureus meaning "golden" in Latin.
The action of hemolysins, toxins produced by certain pathogenic bacteria or fungi, causes hemolysis. Intense physical activity is another cause. Hemolysins cause lysis and eventually cell death by damaging the cytoplasmic membrane of red blood cells.
The action of hemolysins, toxins produced by certain pathogenic bacteria or fungi, is one cause of hemolysis. Intense physical activity is another cause.
Thus, Hemolysins cause lysis and eventually cell death by damaging the cytoplasmic membrane of red blood cells.

What is happening to the chromosomes in this phase of mitosis?
Answer: The answer is A
During mitosis (nuclear division), the chromosomes condense, the nuclear envelope of most cells breaks down, the cytoskeleton reorganizes to form the mitotic spindle, and the chromosomes move to opposite poles. Chromosome segregation is then usually followed by cell division (cytokinesis).
what was the path of darwin’s voyage
Answer:
In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship's naturalist for a trip around the world. For most of the next five years, the Beagle surveyed the coast of South America, leaving Darwin free to explore the continent and islands, including the Galápagos.
Explanation:
Most of the trip was spent sailing around South America. There Darwin spent considerable time ashore collecting plants and animals. Darwin filled notebooks with his observations of plants, animals, and geology. The trip was an almost five-year adventure and the ship returned to Falmouth, England, on October 2, 1836.

The main function of the Rough Endoplasmic Reticulum is the production of membrane and proteins secreted by the cell.
What is Endoplasmic Reticulum?The endoplasmic reticulum serves as the transport system of the eukaryotic cell, with many other important functions such as protein folding. It is a type of organelle made up of two subunits –
1. Rough endoplasmic reticulum (RER)
2. Smooth endoplasmic reticulum (SER)
It has a continuous nuclear envelope. The endoplasmic reticulum contains ribosomal granules anchored to the cytoplasmic surface of the cisternae is involved in the synthesis and secretion of proteins through membrane-bound vesicles called ergastoplasms.
Thus, the main function of the Rough Endoplasmic Reticulum is the production of membrane and proteins secreted by the cell.

Suggest how the scent from the flowers
spreads out into the air
Answer:
through diffusion
Explanation:
I think so that by diffusion this occurs
Answer:
Pollinators which may be insects, birds, or other animals would reach the flower by being stimulated through their sense of smell. The scent from flowers gets spread through the air everywhere because the scent producing molecules are low weight. The low molecular weight help them spread and diffuse everywhere

why do the functions of many receptor kinases depend on the fluid nature of the plasma membrane?
Complete Question
Why do the functions of many receptor kinases depend on the fluid nature of the plasma membrane?
The generation of cAMP requires a fluid membrane.Binding of ligand to the receptor requires a fluid membrane. The receptor monomers must move together and dimerize to be activated. Phosphorylation requires a fluid membrane.We have that
The reason why the functions of many receptor kinases depend on the fluid nature of the plasma membrane is because
Phosphorylation requires a fluid membrane.
Generally

core
Answer:
The Core
Explanation:
The very center of the earth is called the core.
The core layer is located at the center of the Earth.
What is center of earth?All land surfaces on Earth have a geometric center that is located at the planet's geographic center. According to geometry, it is the centroid of all land areas inside the two dimensions of the geoid surface, which roughly represents the exterior shape of the planet.The extremely hot and dense core of our planet is called the Earth's core. Underneath the chilly, brittle crust and the largely solid mantle is the ball-shaped core. The Earth's core is around 2,900 kilometres (1,802 miles) below the surface and has a radius of about 3,485 kilometres.Since the temperature and pressure significantly rise as we travel more inside the planet, we are unable to reach the center of it. Furthermore, there is currently no technology that can penetrate the depths of the earth.To learn more about center of earth refer to:
