Answer: Lysosomes
Explanation:
Lysosomes have 3 functions that help the cell, they break down excess or worn-out cell parts. They destroy invading viruses and bacteria. , lysosomes can also perform a "self-destruct" in a process called programmed cell death, or apoptosis whenever the cell is damaged beyond repair.

Variation in carbon chains is an important source of molecular complexity. How can carbon skeletons vary?.
Answer:Covalent bonds link carbon atoms together in long chains that form the skeletal framework for organic molecules. These carbon skeletons may vary in: ... Compounds with the same molecular formula but with different structures and hence different properties. Isomers are a source of variation among organic molecules.
Explanation:
The carbon skeletons may vary in:
lengthShapeNumber and location of double bondWhat is carbon skeletons?The term carbon skeleton is utilized to depict the example where the carbon iotas are reinforced together in a particle, ignoring molecules of different components and contrasts among single and numerous bonds.
Most substance responses of natural mixtures don't break connections between carbon iotas and thusly leave the carbon skeleton unaltered. In numerous isoprenoids, rings of three, four, or five carbon iotas structure part of the atomic design.

Proteins to be secreted outside the cell are formed at ribosomes on the surface of the ______ endoplasmic reticulum.
Answer:
Proteins to be secreted outside the cell are formed at ribosomes on the surface of the rough endoplasmic reticulum.
Proteins to be secreted outside the cell are formed at ribosomes on the surface of the rough endoplasmic reticulum.
How protein is synthesized?Ribosomes, which are tiny, elongated organelles with a round shape, are found on the rough endoplasmic reticulum and are responsible for producing those proteins.
After prolonged chase times, secretory vesicles carrying the radiolabeled proteins from the Golgi apparatus to the cell surface merged with the plasma membrane to discharge their contents outside of the cell.
While the smooth endoplasmic reticulum does not contain ribosomes and produces lipids and helps the cell detoxify, the rough endoplasmic reticulum produces protein and contains ribosomes.
Therefore, the rough endoplasmic reticulum is responsible to synthesize proteins to be secreted outside the cell.

What did gregor mendel use to discover the principles that rule heredity?.
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

1.) You lie deep in the Earth's crust.
2.) You slowly melt from the heat of the earth's mantle,
3.) You erupt out of a volcano as liquid rock (lava) and harden in the cool
air.
What rock do you change into?
There are three types of rocks according to how they get formed. Igneous rocks come from the Earth's interior as lava and erupt out of a volcano, getting cold and solidifying when get in touch with air.
Types of rocks
According to how they get formed, we can mention three different main types of rocks,
MetamorphicIgneousSedimentaryIgneous Rocks
These rocks come straight from the interior of the Earth.
A liquid mass of silicate composition coming from the Earth's core erupts out of a volcano as lava.
Since this melted mass comes from the Earth's interior, its temperature is extremely high.
Lava begins to cool and solidify during its ascent to the Earth's surface.
Igneous rocks are produced by the cooling of magma when they get in touch with air.

What enzyme is needed to convert testosterone to dihydrotestosterone?.
Answer:
5-alpha reductase
Explanation:
The 5 alpha-reductase enzyme acts on these target tissues to convert testosterone to DHT. DHT is largely a paracrine hormone because of this isolated synthesis at a particular target tissue. It is mostly produced in the liver, therefore the systemic circulation only contains modest levels of it.
What role of 5-alpha reductase enzyme?The enzyme 5 alpha-reductase converts testosterone to DHT. The need for 5 -reductase differs with different tissues, as demonstrated by the autosomal recessive genetic condition 5 -reductase deficiency.
By acting on certain target tissues, the 5 alpha-reductase enzyme transforms testosterone to DHT. DHT is largely a paracrine hormone due to this isolated synthesis at a specific target tissue. Only trace levels are seen in the systemic circulation because it is primarily synthesized in the liver.
Therefore, 5-alpha reductase enzyme is needed to convert testosterone to dihydrotestosterone.
