Which of the following is the main evidence of life in the early universe?

1 answer:

6 0

For number 1 is cyanobacteria

For number two is D

For number 5 I think is the striking similarities at early development stages is evidence that they came from a common ancestor.

I hope this helps.

Suppose the frameshift mutation was still present, but now there was a base substitution (A to C) in the arginine (R) codon, cha

maksim [4K]

Answer:

A. The rest is still out of frame

Explanation:

The mRNA codon translated to amino acids is placed below.

While serine, which is one of the amino acids in the original protein, is still there as a part of the new sequence, there are a host of other frame shift mutations. While it is possible to phosphorylate a serine in any of these amino acid sequences, the secondary and tertiary structure of these are different to each other.

Original:

5' - UG | GUC | GGC | GAG | AAC | GAA | AGC | GC - 3'

Val Gly Glu Asn Glu Ser

Mutation:

5' - UG | GUC | GGG | AGC | ACG | AAA | GCG | C - 3'

Val Gly Ser Thr Lys Ala

Why was matthias Jacob Schleidens discovery important?

Salsk061 [2.6K]

Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.

C. At what height would the pomegranate have the same potential energy as the melon? (1 point)

zvonat [6]

Answer:

Given a set of assumptions which are given below, the height at which the pomegranate will have the same potential energy as the melon is 39.19 meters.

Explanation:

Gravitational Potential Energy refers to the acquired innate energy of an object due to its elevation above the surface of the earth.

This energy is the result of gravitational pull or force acting on the object.

In other to determine at what height a pomegranate and a watermelon will have the same potential energy we need to know the other factors in play.

Gravitational Potential Energy (Ep)= mgh

Where m = Mass (kg)

g = gravitational field strength (N/kg)

h = height (m)

Ep = gravitational potential energy ( j )

Let us assume that the

An average pomegranate weighs about 0.255146Kg

An average melon weighs about 10Kg
g is always constant at 9.8 N/kg

Note that melons weight much more than pomegranates.

So, let's calculate for the Ep of the melon at the height of 1 meter

Ep = 10 x 9.8 X 1 = 98j

Using the above assumptions, we do a goal seek using Microsoft Excel. Please see the attached image.

Calculation shows that the Height (h/Meters) at which the Ep of both veggies become equal is 39.19m

This can be verified by inserting the figure and multiplying it. It can also be calculated as follows:

That is

Ep = 98j

m = 0.255146kg

g= 9.8kg

h= ?

98= 0.255146 x 9.8 x h

98 = 2.5004308h (we divide both sides by 2.5004308 to make h the subject matter)

h = 98 / 2.5004308

h = 39.1932462198

Which is approximately 39.19
