There will be more guinea pigs in a population with long fur than there are short fur.
Lelu [443]3 years ago

If for the guinea pigs is advantageous to have long fur in order for them to survive, than it can be expected that the guinea pigs will have longer and thicker fur.

This will happen because of the evolutionary pressure to survive, and also because of natural selection, where in the mating it will be advantageous to mate with an individual that has longer fur, while the ones with shorter will be rejected, thus they will not transfer their genes.

Apart from growing a long fur, it will for sure become thicker as well, and probably a layer of thicker skin for better isolation from the cold.

Sphinxa [80]
Interphase: You could not distinguish any parts of the cell.
Prophase: You could clearly see the chromosomes throughout the cell.
Metaphase: The chromosomes where lines up in the middle of the cell.
Anaphase: You could see the chromosomes were separated to ether side of the cell.
Telophase: The entire cell was separated to each side but was not split into its own cell.
Cytokinesis: In this step the cell had totally separated and there was now two separate daughter cells.

____ [38]

Answer:

The reactivity greatens the farther you go down on the periodic table. Lithium will have the weakest reaction, and cesium will have the greatest reaction. Patterns like this are useful to scientists because it shows which elements are the most reactive and which aren't. The farther down and to the left you go within the periodic table, the more reactive the elements become. The farther up and to the right you go, the less reactive they become.

What happens to excess carbohydrates in animals?
Neporo4naja [7]
<span>Excess carbohydrates in Animals are stored as fats. It mainly gets stored in the skeletal muscles and liver in the form of glycogen. Carbohydrates actually get stored in the form of long polymers of glucose molecules or as glycogen starch. They provide energy to the animals for performing their daily duties. Carbohydrates are generally considered the fuel for all organisms, and without this most animals would become sloth and would be unable to perform the regular jobs. Carbohydrates are actually very easy to metabolise and hence generate quick energy. </span>

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.
