PLEASE HELP ASAP List and describe the five steps to form sedimentary rocks.

1 answer:

3 0

Formation of Sedimentary Rocks Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.

Sure hope this helps you

The major buffer in blood is composed of the weak acid carbonic acid (H2CO3) and its conjugate base, bicarbonate ion (HCO3 - ).

tatuchka [14]

Answer:

The increase in the amount of carbon dioxide in in blood will lead to respiratory acidosis

Explanation:

Carbon dioxide in its normal level between 38 to 42 mm Hg plays vital roles in the human body like regulating the PH of the human blood, breathing regulation and other things. If the amount of carbon dioxide is high more than the range level, it will cause what is called respiratory acidosis.

Respiratory acidosis is a situation in cause by decrease in ventilation i.e Oxygen level leading to increase in carbon dioxide and drop in PH level of the blood.

Suppose two independently assorting genes are involved in the pathway that determines fruit color in squash. These genes interac

Answer:

100% yellow fruit color, Yyww.

Explanation:

Available data:

two independently assorting genes

the W allele codes for a dominant white phenotype

w allele codes for a colored squash

The allele Y codes for a dominant yellow phenotype

the allele y codes for a recessive green phenotype

The phenotypes from the first locus will always mask the phenotype produced by the second locus if the dominant allele (W) is present at the first locus. This masking pattern is known as dominant epistasis

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is dominant, the interaction is known as "dominant epistasis".

W suppresses the expression of Y and y, this means that whenever W is present, the fruit is white. If W is not present, the fruit color can be expressed.

So, the proposed cross in the present problem occurs between a green fruited individual and yellow fruited individual, which suggests that W is absent.

Genotype for Green fruit: yyww

Genotype for purebred Yellow fruit: YYww

Cross:

Parental) YYww x yyww

Gametes) Yw Yw Yw Yw yw yw yw yw

Punnet square) Yw Yw Yw Yw

yw Yyww Yyww Yyww Yyww

F1) 100% Yellow fruited plants, Yyww

As these two genes assort independently, we can also represent the cross for each gene by separate, like this:

For w gene:

Parental) ww x ww

Gametes) w w w w

Punnet square) w w

w ww ww

F1) 4/4 or 100% colored-fruits

For Y gene:

Parental) YY x yy

Gametes) Y Y y y

Punnet square) Y Y

y Yy Yy

F1) 4/4 or 100% yellow fruits, Yy.

what are some advantages and disadvantages of using permanent slides as opposed to temporary slides to view tiny aquatic animals

nikitadnepr [17]

Answer:

Permanent slides ensures preservation of the body parts of the tiny aquatic animals and also also aids good visualization.Most of the exoskeleton of these tiny animals are lost during temporary slides preparation, thus loss of visualization.

Because the animals are transfixed to a point, their body parts can not be moved.

It also saves time, energy and resources spent during observation.

However,because of dehydration during preparation their natural color may be lost which may affect observation of natural features

Why is diffusion such an efficient process for all cells?

kirza4 [7]

Answer: A

Explanation: Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.
