Scientific inquiry is asking a question about the world and finding out an answer or explanation in order <span>to develop explanations of natural phenomena in a continuing and creative process. It is very important to follow safety rules during every scientific inquiry:
</span><span>1.Do not taste, touch, or smell substances unless directed to do so.
</span><span>2.Wear safety glasses and other required safety equipment.
</span><span>3. Keep the lab area, including table top and walkways, clear of unnecessary items.
4. </span>H<span>andle all equipment carefully and as directed.</span>

What Earth science concept explains the process of the cooling of magma into porous rock? Explain your answer. plz answer correc
Zolol [24]
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).

Ben Affleck has a cleft chin, but his ex-wife Jennifer Garner does not. Neither one of their two daughters (Violet and Seraphina
kherson [118]

Answer:

Ben - Y Xc

Jen - XCXC

Violet - XCXc

Seraphina - XCXc

Samuel- Y Xc

Explanation:

Given -

Ben has a cleft chin

Let the allele for cleft chin be "c"

and the allele for normal chin be "C"

When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.

This means that the allele C could be X -linked and the mother is not the carrier but the father is

The genotype of father Ben would be Y Xc

Genotype of mother would be XCXC

Genotype of two daughters XCXc  , XCXc which means they are carrier for the next generation

Genotype of Boy - Y Xc

Meiosis and mitosis are both forms of cell division. However, the outcomes of these processes differ. Consider a diploid organis
aleksandr82 [10.1K]

Answer:

Meiosis produces four genetically different haploid cells.

Gametic chromosomes have a different combination of alleles than parental chromosomes as a result of independent assortment

Explanation:

Meiosis and Mitosis are two types of cell division that occurs in living organisms. However, Mitosis produces daughter cells that are genetically identical to the parent cell while meiosis produces daughter cells that are genetically different from the parent cell. This accounts for the reason meiosis leads to genetic variation.

The production of genetically different cells by meiosis is as a result of the process of the random orientation of chromosomes during metaphase I of meiosis I. This process is called INDEPENDENT ASSORTMENT. However, crossing over occurs during prophase I of meiosis between non-sister chromatids of homologous chromosomes.

Chaperone proteins or chaperones assist in the proper folding of proteins. Explain the process.
oksian1 [2.3K]

Proteostasis is mediated by chaperone proteins and protease systems, together with cellular clearance mechanisms such as autophagy and lysosomal degradation.

Chaperone proteins control assembly and inaccurate folding by binding to and stabilizing partly or completely unfolded protein polypeptides till the polypeptide chain is completely synthesized. Chaperone proteins also confirm the stability of unfolded polypeptide chains as they are being translocated into the subcellular organelles.
