7 0

The answer is down the molecule's concentration gradient. To simplify, the movement of molecules through a plasma membrane channel protein is always down the molecule's concentration gradient. In addition, carrier proteins and channel proteins are the two main classes of membrane transport proteins. The carrier proteins bind the specific solute to be transported and undergo a series of conformational changes to transfer the bound solute across the membrane.

Cows, pigs, and sheep have identical amino acid sequences for cytochrome c. What does this say about their evolutionary relatedn

MrMuchimi

Answer:

It shows the three organisms to have evolved from a common ancestor.

Explanation:

An identical sequence of amino acids for cytochrome c in cows, pigs and sheep show that they most likely evolved from a common ancestor. The common ancestor might have evolved over time and in result, three different species were produced. It also shows that they are more closely related to one another than other organisms.

Other properties or traits that are common in these organisms are :

They all are mammals.

They are all livestock animals.

They all are multicellular organisms.

$\huge{\green}\fcolorbox{blue}{cyan}{\bf{\underline{\red{\color{red}Answer}}}}$

The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics.
Whereas the phenotype is the physical appearance or characteristic of the organism.
Thus, we can find the human genetic code with the help of their genotype.
Organisms may look the same but still may not have the same genotype.
One can determine the genotype by the biological tests.
On the other hand, the phenotype is determined by an individual’s genotype and can be expressed as genes or by the visible traits.
Such traits are hair color or type, eye color body shape, and height, and many such more.
It will depend on the genotype but also influenced by the factors existing in the surrounding.
