Answer is 90 percent.

There are 10 times more bacterial cells in our body than the human cells, according to Carolyn Bohach, a microbiologist at the University of Idaho (U.I.) Although bacterial cells are very large in numbers but these cells take up small space due to smaller than human cells. Babies ingest bacteria during birthing. Babies take up lots of bacteria from their mother's skin and milk—during breast-feeding, the mammary glands become colonized with bacteria. Throughout our lives, we take up bacteria through our food and water.

Two insect groups vary genetically by two genes. When put together,they were able to reproduce and produce offspring that could

nikitadnepr [17]

<h3>Your answer is D.</h3>

The insects are the same species.

<h3>Explanation:</h3>

A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.

There are 258 g of MgCl2/liter. What is the molarity of the solution?

Zolol [24]

Taking into account the definition of molarity, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

<h3>Definition of molarity</h3>

Molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

molarity= number of moles÷ volume

<h3>Molarity of the solution in this case</h3>

In this case, you know that the molar mass of MgCl₂ is 95.21 g/mole [molar mass is the amount of mass that a substance contains in one mole.]

You can apply the following rule of three: If by definition of molar mass 95.21 grams are contained in 1 mole, 258 grams are contained in how many moles?

amount of moles= (258 grams× 1 mole)÷ 95.21 grams

<u><em>amount of moles= 2.7098 moles</em></u>

Replacing in the definition of molarity:

258 g of MgCl₂/liter= <u><em>2.7098 moles of MgCl₂/liter</em></u>

<em />

Finally, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

Which type of succession occurs when communities form in an area that was previously uninhabited by organisms?.

Ghella [55]

Answer:

Secondary succession

Explanation:

When a previously occupied area gets colonized by a new dominant group of species or communities, this is known as secondary succession. In secondary succession, new residents take the place of earlier groups in a habitat that has been affected by an ecological disturbance.

List the order of Producers that colonize the land After Lichens

olasank [31]

Answer:

Plant is a common example of a Producer.

Producers are also known as autotrophs.They are organisms which make their own food. They do so by getting energy from chemicals or the sun and with the help of water convert the energy into useable forms such as sugar.

The order of Producers that colonize the land After Lichens include

Annual herbaceous plants

Perennial herbaceous plants and grasses

Shrubs

Shade intolerant trees

Shade tolerant trees.
