Answer;

C.) during prophase

Explanation;

-Prophase is the first phase of mitosis, the process of cell division in which a parent cell divides into two daughter cells that are similar to the parent cell, and is separated into four stages.

-During this phase of mitosis each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers.

-Initially, prior to prophase, the chromosomes were long strands of DNA material called 'chromatin', which then curls up into tightly wound shapes called chromosomes.

What is the term for metabolic pathways that release stored energy by breaking down complex molecules?
kap26 [50]

Answer:

(B) Catabolic pathways.

Explanation:

Catabolic pathway is the breaking down or degradation of complex molecules into simple molecules. Catabolic pathways are exergonic reactions because in the process of degradation, energy stored in these complex molecules is released. These reactions are spontaneous.

Examples of catabolic pathways are glycolysis, citric acid cycle, the breakdown of fat in adipose tissue to fatty acids, etc.

What are the main types of rocks and how are they classified?(I need help!!!!)
KATRIN_1 [288]

Sedimentary

Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment. Gradually, the sediment accumulates in layers and over a long period of time hardens into rock. Generally, sedimentary rock is fairly soft and may break apart or crumble easily. You can often see sand, pebbles, or stones in the rock, and it is usually the only type that contains fossils.

Examples of this rock type include conglomerate and limestone.

Metamorphic

Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing). The rocks that result from these processes often have ribbonlike layers and may have shiny crystals, formed by minerals growing slowly over time, on their surface.

Examples of this rock type include gneiss and marble.

Igneous

Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens. Sometimes the magma cools inside the earth, and other times it erupts onto the surface from volcanoes (in this case, it is called lava). When lava cools very quickly, no crystals form and the rock looks shiny and glasslike. Sometimes gas bubbles are trapped in the rock during the cooling process, leaving tiny holes and spaces in the rock.

hope this helps, please mark brainliest :)
