Everyone knows about the human DNA and law of inheritance among these Chromosomes are thread like structures in thee Nucleus where DNA molecules are packed.

chromosomes are the building blocks of the human body as it is further divided into centro-mere which are also its arms. the shorter is S arm and the longer is its Q arm. the centro-mere being located in the structure gives it a specific shape.

1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.

2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.

3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches

4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

I tried my best hope this helps :)

Plant cells form a cleavage furrow or indentation of membrane between new daughter cells.

<h2>Mitosis Process</h2>

Explanation:

  • Plant cells and animal cells undergo the same cellular processes during mitosis.
  1. The centrioles absent in the plant.
  2. Animals  cells have centrioles, to what delivers the shaft strands is one of the differences among plant and creature mitosis.
  3. The periods of mitosis and goes on in each stage is the equivalent aside from when it comes to how cytokinesis is practiced.
  4. <em>Plant cells separate the cytoplasm between the two new cores by framing a cell plate (new cell wall)between the cores.</em>
  5. Animals cells achieve this by shaping a cleavage wrinkle which is a squeezing in at the center of the<em> </em><em>cell until two new cells have been framed with cytoplasm and organelles for each  new nuclei.</em>

A student named Janine says that the measure of side b is 64 ft. Please state whether this is correct or incorrect. If this is i
kolezko [41]

The measure of side b as 64 ft is incorrect. The accurate measure would be 8 ft.

According to the Pythagorean theorem, the square of the hypotenuse of a right-angle triangle is the sum of squares of the opposite and the adjacent sides. Mathematically:

hypotenuse^2 = opposite^2 + adjacent^2

In this case, the hypotenuse = 10 ft, the opposite = 6 ft and the adjacent = b

Hence,

b^2 = 10^2 - 6^2

       = 100 - 36

          = 64

b = √64

     = 8 ft

Thus, the side b is 8 ft and not 64 ft.

PLEASE HELP! Emma prepared two glasses of water at two different temperatures. She added a spoonful of table salt to the cold wa
Sergio039 [100]

Answer:

The correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

Explanation:

For the majority of the solids dissolved in water, the solubility increases with temperature increments. Higher temperatures accompany the increase in kinetic energy permits the solvent particles to more adequately break apart the solute atoms that shows intermolecular attractions.

So if glass one dissolves the salt faster than glass two then it is clear that glass one has more temperature than glass two that takes more time to dissolve the rock salt.

Thus, the correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.
