The most common human variants are those that vary gradually instead of having defined boundaries as would be expected as cine

The correct answer is A

For issues that don't call for irregular change and that can be improved continuously and sustainably, gradual change is an more stable method. When there is divided government, modest, incremental adjustments are frequently the only way any change could take place.

Instead of happening all at once, a progressive process or change happens in little increments over time. A steady, sluggish procedure is required to lose weight. Synonyms include steady, even, sluggish, and regular Alternative Words for gradual

Four cell organelles in living cells are: mitochondria, nucleus, ribosomes and endoplasmic reticulum.

The mitochondria refers to that organelle found in the cytoplasm which is regarded as the power house of cells.

That being said, a cell is defined as the structural, functional and basic unit of life.

So therefore, it can be deduced from the task above that ribosomes and mitochondria are some of the few organelles in the cells of living organisms.

Differentiate between the lysogenic and lytic cycles The virus injects DNA into the host cell during the lysogenic cycle.

The lytic cycle includes the replica of viruses using a number cellular to fabricate greater viruses; the viruses then burst out of the cellular. The lysogenic cycle involves the incorporation of the viral genome into the host cellular genome, infecting it from inside.

Inside the lytic cycle, the viral genome does no longer comprise into the host genome. within the lysogenic cycle, the viral genome consists of into the host genome and stays there throughou The main difference among lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell while lysogenic cycle does no longer spoil the host mobile

The primary difference between lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell whereas lysogenic cycle does not destroy the host cell. Viral DNA destroys the host cell DNA and arrests the cellular features within the lytic cycle. but, in the lysogenic cycle, viral DNA may merge with the host.

Water is a good insulator

Explanation:

This is because water is very healthy for our body making us not dehydrate

The density of lions per each km² in the portion of the park that has been studied is 0.05125 lions/km², i.e., in this case this value equals to 41 lions/800 km².

The population density in a natural population can be obtained by dividing the number of individuals or organisms of a given species per unit of surface area in the ecosystem under study.

In this case, the studied area is 800 km² because it represents 20 percent (i.e. 20%) of an area that has 4000 km², while the number of lions in this area represents the population density and can be obtained as 41 lions/800 km2 >> 0.05125 lions per km².

Therefore, with this data, we can see that the population density is associated with the number of organisms of the same species in a given geographic area, which is generally referred to as the number of individuals per km².

Pressure builds up whenever there is friction and air. And if both are present, it deforms the set. In order for friction to work, pressure and air both are important.

What is friction, deformation, air pressure and force?

Friction: the force that resists against the relative layers of liquids, solids and other materials as they slide over each other.

Deformation: It is the continuous mechanical transformation of a body from a reference configuration to its current configuration. A configuration is a set containing the positions of all particles in a body.

Air pressure: The force exerted by compressed or free air on a surface it comes in contact with.

Force: Influences that can change the movement of an object. A force can change the velocity of an object with mass, i.e. accelerate it.

RBC’s make up about 84% of cells in the body, but they are only 4% of body weight. Whereas, 75% of total weight are fat cells and muscle cells. They’re both large cells but constitute only a minute fraction of the total number of cells.

How many cells is the human body made of?

The exact number of cells is still debatable. But to put it briefly, around 30-40 trillion. The long answer? Not yet determined.

What we do know, is that RBC’s (red blood cells) make up the majority of cells in our bodies. They make up only 4% of total mass, despite constituting 80% of all cells. The reason is that RBC’s measure 8 micrometers in diameter.  The size of fat cells, however is around 100 micrometers.

The total number of cells to this date is still not defined, but we have a slight idea of what could be.

Therefore, the reason for RBC’s having 84% of cells and 75% of fat cells is their mass. RBC’s are only 4% of total weight because their measure is only 8 micrometers. Whereas fat cells are around 100 micrometers in diameter.
