The concentration of nitrates is often higher in

Phoenix [80]

Answer:

(2) diffusion

Explanation:

Diffusion is a process in which molecules moves from a region of higher concentration to the region of lower concentration. In this condition, plant roots contain high concentration of nitrates than soil so nitrates moves from roots through semi-permeable to the soil by the action of diffusion until the concentration is uniform or equilibrium.

<h2>The Protein Structure</h2>

Explanation:

Protein structure is the three dimensional game plan of particles in an amino corrosive chain atom.
Proteins are polymers explicitly polypeptides framed from groupings of amino acids, the monomers of the polymer.By show, a chain under 30 amino acids is regularly distinguished as a peptide, rather than of a protein.
All proteins have primary, auxiliary and tertiary structures yet quaternary structures possibly emerge when a protein is comprised of at least two polypeptide chains.
The collapsing of proteins is additionally determined and fortified by the arrangement of numerous bonds between various pieces of the chain.
Connective tissues for the most part have barely any cells and extensive extracellular filaments including collagen and elastin.
Collagen is the absolute most abundant protein in the creature body and establishes roughly 25–35% of the entire body content.

Which of the following statements about autosomal recessive traits is true?

meriva

Answer:

A. If neither parent expresses the trait, but the offspring does, both parents must be heterozygous for the trait.

Explanation:

If neither parents express the trait is because they are heterozygous and the dominant allele is being expressed over the recessive trait. When parents cross they have 25% of having an offspring that expresses the recessive trait, this means the offspring is a recessive homozygous. In the attached example 25% or 1/4 will have a short stem.

kotegsom [21]

Answer:

All cells exhibit basic structural similarities. The general plan of cellular organization varies between different organisms, but despite these modifications, all cells resemble one another in certain fundamental ways. Match each description with a feature. separates contents of cell from surroundings made up of contains sugars, salts, and amino acids contains prokaryotic DNA contains eukaryotic DNA matrix?

1. Prokaryotic and eukaryotic cells both has a nucloid/nucleus, organelles, cell membrane, contains ribosomes, has cytoplasm

2. Nucleus; contains eukaryotic DNA

3; Nucloid; contains prokaryotic DNA

4; Cytoplasm; semi fluid matrix, contains sugars salt and amino acids

Explanation:

The cell from latin cella, meaning "small room" is the basic structural, functional and biological units of all known organisms. A cell is the smallest units of life and they are often called the building blocks of life the study of cell is called cytology. cells contains cytoplasm enclosed within a membrane which contains many biomolecules such as potein and nucleic acids. most plants and animal cells are only visible under a microscope with dimensions between 1 and 100 micrometers.
