1. The formula for calculating the surface area of a cube is:
goldfiish [28.3K]

Answer:

The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the length of one side of a cube. We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube.

Need a hypothesis for “How are proteins built from RNA”
Dima020 [189]

Hi!


Hypothesis:

<em>Proteins are built from the translation of messenger RNA (mRNA) molecules</em>


RNA, or ribonucleic acid, is a structure that is similar to DNA, except that it exists as a single strand, consists of a ribose sugar instead of a deoxyribose sugar and has the base uracil (U) instead of thyamine (T).


<h3><u>From DNA to RNA</u></h3>

RNA is generated through transcription of the DNA molecule, resulting in a <em>complementary </em>molecule of the template DNA strand. For instance, if the sequence of the DNA was:

ATGCGCAGTTATTGCGAT

The corresponding RNA sequence will be:

UACGCGUCAAUAACGCUA    <em>(complementary with U instead of T)</em>


<h3><u>From RNA to Protein</u></h3>

The RNA molecule in our case is known as the mRNA. After transcription the mRNA molecule is transported to the cytoplasm, where a ribosome binds to it for another molecule to translate the sequence. This translation is mediated by an RNA molecule known as the tRNA molecule which enters the ribosome to catalyze the reaction.

These molecules identify a sequence of 3 bases (codon) and for specific codon sequences, the tRNA allocates specific amino acid. For instance, for the codon <em>UCA</em>, the tRNA will allocate a <em>Serine residue.</em>

This translation process starts at specific three base sequences, known as start codons, and terminates at specific three base sequences known as stop codons.

In this manner, a sequence of amino acids respective to the mRNA codon sequence is synthesized, and as we identify proteins as chains of amino acids that are covalently linked together through peptide bonds, we can clearly see that proteins are built directly from RNA, and indirectly from DNA.


Hope this helps!

_____is an interaction between species that affects both species negatively (-/-), as they utilize similar resources.
jolli1 [7]

An interaction between species that affects both species negatively (-/-) , as they utilize similar resources is called as Competition .

Competition :

Competition is a process in which the fitness of individual of one species is significantly lower than that of the individual of same or different species.

Types of competition :

For the necessities of life , it is divided into two types .they are as follows,

A) interspecific competition : it is a competition which occurs between the individuals of two different species having some requirements of life , e.g.,carnivorous animals such as tiger ,lion ,leopard etc .compete for the prey . in the forest habitat ,herbs and trees compete for sunlight , water space , minerals , and biological pollinators .

If the individuals of two different species have sme one or more requirement the the competition becomes very severe e.g., grassland is the common habitat for bison ,dear rabbits ,rats grasshoppers , etc .if thee is short supply of grass due to draught then the competition becomes severe

The survival of the consumers is determined by the quantity of grass required by each species ,ability to change the food and its capacity to migrate to new localities.

B) Intraspecific competition : it occurs between the individuals of the same species .this type of competition is very severe as all the individuals of the same species have almost common requirement of food ,habit etc .besides they also exhibits similar adaptations to fulfill their requirements ,e.g., animals of same species compete for water ,food and mates .

Intraspecific competition is the driving force behind evolution and natural selection .

Thus the Competition only negative impact on environment.
