The question is incomplete; the complete question is;

Root cells of plants take in some minerals from the surrounding soil by spending energy. After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil. Which reason best explains why root cells need to spend energy in order to transport some minerals into cells?

Root cells are unable to use sunlight energy for mineral uptake.

Mineral concentration is higher in root cells than in the surrounding soil

Cell membrane pores in roots are too small for passive uptake of minerals

Cell membranes in roots lack proteins for the passage of minerals.

Answer:

Mineral concentration is higher in root cells than in the surrounding soil

Explanation:

Mineral uptake by plant roots occurs by active transport of ions into the cells of root hairs, this process requires energy.

The concentration of minerals in the soil is quite low. The root hair cells of plants possess carrier proteins that carry mineral ions and move them into the cell against existing concentration gradient. This process requires energy and is known as active transport.

Stells [14]

If they remain isolated for a long period of time, the two groups will probably diverge genetically, and may result in speciation.

Genetic divergence is the process whereby two groups of the same ancestral species acquire autonomous genetic changes through time, usually after the groups have been separated reproductively for some period of time.

Speciation is an evolutionary process whereby populations develop to become different species.

Let’s suppose a sheep that provided the oocyte for reproductive cloning was homozygous for a gene that causes a small head. This
Misha Larkins [42]

Answer:

Small head

Explanation:

Since the genes are located in the nucleus of a cell which has being removed (but some genes are still located in the mitochondria of the ocyte) from its ocyte to fuse it with with another nucleus. Since the cell follows a maternal inheritance of gene, it would have a small head because of the presence genes in the mitochondria.

What is the relationship between Endomembrane System, Insulin and Insulin Receptor, activation by phosphorylation, membrane-boun
mars1129 [50]

Answer:

The relationship between endomembrane system, insulin and insulin receptor, activation by phosphorylation, membrane-bound polyribosomes, and glucose transport channels is the eukariotic cell, because within it, they work together with the organelles to modify, summarize and transport lipids and proteins from the gut and absorb nutrients.

Explanation:

The Endomembrane system varies from membranes and organelles, but basically, it is structured by the nuclear envelope and lysosomes, the plasma membrane and several cytoplasmic organelles, as the ER, the Golgi apparatus, secretory granules, vesicles, lysosomes, endosomes, and the endoplasmic reticulum all working together to transfer, modify and package lipids and proteins macromoecules to the eukaryotic cell, from one part of it  to another, and from in to the outside of it also.

The membrane bound polyribosomes are attached to the cell endoplasmic reticulum. The bound ribosomes, used within the cell membrane or expelled from the cell by exocytosis, will produce insulin and they will become membrane bound to control the intake, protein modifications, fusion lipids and sugar breakdown. The insulin is a membrane bound polyribosomes protein synthesized in the ER, which travels along the endomembrane system. This hormone controls glucose and lipid metabolism  or energy function, if glucose level is high, insulin synthesis is activated.  

Synthesized and traveling through the endomembrane system, the insulin gets to its receptor called tyrosine kinase and activates it, phosphorylating and recruiting different substrate adaptors.

 The brand new insulin polypeptide chains go directly into the endoplasmic reticulum by the ribosome and then transported to where they are needed as insulin regulates sugar uptake into adipose tissue and skeletal muscle through glucose transport channels or glucose transporters GLUT4 within vesicles, which are directed to the plasma membrane, this is also the gut and nutrient absorption.
