Answer:
In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many <u>hydrogen</u> bonds
Explanation:
In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.
A tissue is a group of similar cells and their intercellular materials in a discrete region of an organ performing a specific function. <span>There
are five levels of organization and these are the cells, tissues, organs, organ
systems and organism. The most complex is the organism having the rest of the
organization in it and the least complex is the cell, the basic unit of
structure. The human body tissue is an organized group of cells that is formed to create a muscle or an organ. There are four types of human body tissue: muscle, epithelial, connective and nervous tissue. Each function according to how they are grouped.</span>
Answer:
D) The exact mixture of components varies from point to point.
Explanation:
It's important to know that the air is a mixture formed by around 78% of nitrogen, 21% of oxygen, 0.9% of argon, 0.04% of carbon dioxide, and other gases in smaller amounts.
Additionally, the mixture that formed the air is not always the same, it variates depending on several variables, that means the air as such can slightly change is mixture, at some points can have a bit more oxygen or a bit more carbon dioxide. In other words, the air is not a constant mixture.
Having said that, the right answer is D, because the mixture of components can actually vary from point to point.
All would be affected because decomposers like to break down dead things meaning dead plants AND animals
No. Yes phenotypes are important for example those with longer legs can run faster and hence escape predators
But genes also code for unseen proteins
For example, if a disease is introduced those with long legs won't survive but those who have the genes which code for the complimentary antibody have the ability to kill the pathogen and hence survive.
