And: Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins. Some molecules and ions such as glucose, sodium ions, and chloride ions are unable to pass through the phospholipid bilayer of cell membranes.

Rock B reacts with hydrochloric acid. State the name of the rock B
choli [55]

Answer:

The sedimentary rock limestone which contains carbonate mineral Calcite and the metamorphic rocks which contain carbonate mineral Aragonite are the examples of rocks which react strongly with hydrochloric acid.

Explanation:

Rocks are naturally occurring structures formed on the Earth's crust and are composed of aggregate minerals. Classification of rocks: Igneous rocks - formed by cooling of magma on Earth's crust or seabed (basalts, gabbros, granite, etc), sedimentary rocks - formed over time by the accumulation of sediments from the weathering of existing rocks or fragments of minerals and organisms (mudstone, sandstone, shale, limestone, dolostone, siltstone, etc) and metamorphic rocks - transformed rocks formed from the existing rocks that are subjected to large pressures and temperatures (schists, gneiss, marble, etc).

The carbonate minerals like calcite, dolomite, aragonite, etc react with hydrochloric acid and release carbon dioxide gas bubbles. Calcite (calcium carbonate), which is found in igneous, metamorphic, and sedimentary rocks in a varying proportion reacts strongly with hydrochloric acid. So, the sedimentary rock Limestone which mainly contains calcite react strongly with the acid while Dolostone which mainly contains dolomite (calcium magnesium carbonate) reacts less vigorously. Another carbonate mineral aragonite, found in metamorphic rocks also reacts strongly with hydrochloric acid.

Which assumption must be correct for a population to be in hardy-weinberg equilibrium for a specific gene? see section 23.1 ( pa
Goshia [24]

There are five basic Hardy-Weinberg assumptions:

1. Random Mating -

2. No natural selection - all members of the parental generation survived and contributed equal numbers of gametes to the gene pool, no matter the genotype

3. No genetic drift (random allele frequency changes) - the population is infinitely large.

4. No gene flow - no new alleles were added by immigration or lost through emigration (no migration)

5. No mutation -  There must be mutation equilibrium.

How could natural selection affect humans?
mario62 [17]

Answer:

Explanation:

an example is the ability to endure the sugar, lactose, in milk. In many places of the world, people can't drink milk in light of the fact that their body turns off the intestinal creation of lactase, a chemical that processes the sugar in the milk.
