Prescribe how mountains change in abiotic conditions with an increase in elevations
olga55 [171]
The first famous natural scientist to determine how plants change with altitude on tall mountains was Alexander Von Humboldt and Aime Bonpland when climbing some very high volcanoes in South America like Chimborazo at well ove 20,000 feet high and they observed that different plants grow at different altitudes as altitude increases so that as the mountain was ascended the new environments of temperature, moisture,etc would become abiotic for the lower plants but acceptable for the higher elevation plants. In these cases in South America, the lower elevations had very warm temperatures and high humidity so would grow tropical plants with probably large leaves like palm trees etc. On the other hand at high elevations the temperature would be significantly decreased and probably humidity decreased too so only rugged plants like say lichens could grow. At intermediate elevations, most likely say pine trees could grow as I know they do at moderate elevations in Honduras for example.

Desmosomes form channels that allow each cardiocyte to electrically stimulate its neighbors. True False
dimulka [17.4K]

Answer:

False

Explanation:

The most specific feature of cardiac muscles is the presence of intercalated discs. Intercalated disc connects the ends of cardiac muscle fibers to one another. The discs have desmosomes and gap junctions. The function of desmosomes is to hold the cardiac fibers together. The gap junctions of cardiac fibers allow muscle action potentials to spread from one cardiac muscle fiber to another. These gap junctions have tubular connexons that form channels and connect the cytosol of adjacent cardiocytes to allow the flow of ions and spread of action potential from one cell to another.

Pairs of Unit Factors, or Genes

Mendel proposed that paired unit factors of heredity were transmitted faithfully from generation to generation by the dissociation and reassociation of paired factors during gametogenesis and fertilization, respectively. After he crossed peas with contrasting traits and found that the recessive trait resurfaced in the F2 generation, Mendel deduced that hereditary factors must be inherited as discrete units. This finding contradicted the belief at that time that parental traits were blended in the offspring.

A gene is made up of short sections of DNA that are contained on a chromosome within the nucleus of a cell. Genes control the development and function of all organs and all working systems in the body. A gene has a certain influence on how the cell works; the same gene in many different cells determines a certain physical or biochemical feature of the whole body (e.g., eye color or reproductive functions). All human cells hold approximately 21,000 different genes.

Genetics is the science of the way traits are passed from parent to offspring. For all forms of life, continuity of the species depends upon the genetic code being passed from parent to offspring. Evolution by natural selection is dependent on traits being heritable. Genetics is very important in human physiology because all attributes of the human body are affected by a person’s genetic code. It can be as simple as eye color, height, or hair color. Or it can be as complex as how well your liver processes toxins, whether you will be prone to heart disease or breast cancer, and whether you will be color

Why<br> are<br> non-engineered or owner-built structures more vulnerable to hazards?
Bond [772]

Answer:

Non-engineered/owner-build structures are more vulnerable because they can be poorly built. Without proper knowledge to build the right structure, the structure is more at risk of abnormalities or destruction from hazards such as rain, hail, strong winds, and debris.

The extracellular matrix is found outside of, but attached to the cell membrane?
VARVARA [1.3K]

Answer:

True

Explanation:

The extracellular matrix is the space surrounding the outside of the cell, and is attached to the cell wall using proteins called integrins. Integrins are imbedded into the plasma to offer support to the structure. Hope this helps!
