Silicate minerals are the most common of Earth's minerals and include quartz,feldspar, mica, amphibole, pyroxene, and olivine. Silica tetrahedra, made up ofsilicon<span> and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.</span>

In the word "claustrophobic" phob is the_____.

snow_tiger [21]

Correct answer: A). Root

The part of the word that can not be broken down is called root word. In the word claustrophobic ''phob'' is the root word. It can not be suffix as a suffix are added after the root word. It cannot be prefixed as it is added before the root word. Here the prefix would be ''claustro'' and suffix would be ''ic''. It cannot be affixed as it contains both suffix and prefix.

Hence, the correct answer would be option A.

In a plant, leaf color and leaf shape are controlled by two linked genes Leaves of the wild-type plant are red. A recessive muta

Brrunno [24]

Solution :

Red is dominant over the white leaves and pointed is dominant over smooth.

Red = R , white = r

Pointed = P , smooth = p

Red, pointed x white,smooth ------ Parents

RRPP rrpp

RP rp ----------------- Gametes

RrPp -------- $F_1$

(red, pointed)

When this $F_1$ is test crossed,

RrPp x rrpp ---- $F_1$ test cross

Gametes → rp

RP ---------- RrPp - red, pointed - 36 parental type

Rp ---------- Rprp - red, smooth - 14 re- combination

rP ----------- rrPp - white pointed - 10 re- combination

rp ----------- rrpp - white, smooth - 40 - parental type

Total = 100

As this ratio is deviating from 1:1:1:1, it indicated the two genes are linked.

Linkage strength = percentage of crossing over = map distance between the genes.

Percentage crossing = recombination frequency = percentage of recombination.

Recombination frequency $=\frac{\text{total no. of recombination}}{\text{total no. of progeny}}\times 100$

$=\frac{14+10}{100} \times 100$

= 24 %

= 24 map units

Describe how the structures of proteins differ from the structures of carbohydrates (150 words)

Veronika [31]

well both are considered macromolecules. proteins are like big lego construction. each single piece gets pieced together to make a larger thing. each single piece is a monomer, and the larger construction is the polymer. the monomers are called amino acids and they get pieced together to form the polymer which is called a protein. the linkage that they use is an amide bond, and in biology it is usually called a peptide bond. carbohydrates can be singular monomers or polymer units. they are made of completely different compounds usually aldehydes or ketones. and they link together through different chemical linkages (acetal or ketal linkages for polymers, hemiacetal or hemiketal linkages for monomers). both can be large, 3D strucutres proteins are only functional as a large, 3D structure, while carbohydrates can be singular. (you might wanna word it differently for safety reason)

Did physical weathering probably form this rock arch quickly or slowly? Explain your response.

marta [7]

Answer:

i'd assume yes

Explanation:

If there was a picture it would help but im going off information i know aboutweathering and ersion.

Yes, physical wearthing did create this arch because waves they carry sedoment pieaces away or off of that rock and it possible could have been frozen off. I belive the proces happen slowy just because of how (big or small which ever one) and it takes time to get an arch that big (or small) to be that shape.

I really tried my best to help you and i hope this is the answer your teacher is looking for! Good luck and please make sure to word it in your own words :)
