Answer:
1. nitrogen fixing bacteria soil converts excess "nitrates"
Explanation:
usually caused by low h2o, water movement and lack of minerals to filter water and kill bacteria..
2 primary components of septic system are tank and a septic pump to regulate waste and store it in a tank underground. when full, a service has to engage in emptying the tank or it will contaminate water supply...
You would be referring to the <em>plant </em>cell.
Answer:
Chloroplasts may be seen on all six sides of a plant cell, which is a three-dimensional entity with typically moderately rounded corners (not in the centre because a big central vacuole fills a very large part of the volume). Chloroplasts are constantly being rearranged by the cell since they are not set in place. Chloroplasts are typically located close to so-called periclinal cell walls, which are oriented in the same 2D orientation as the leaf surface under low light. Chloroplasts seem to "escape" to the anticlinal walls in bright light. Better light harvesting in low light by exposing every chloroplast to light and photoprotection by mutual shading in strong light are likely the fitness benefits provided by this behavior. In the dark, chloroplasts also gravitate toward the anticlinal walls. Thin leaves of submerged aquatic plants like Elodea can be used as microscope specimens to observe chloroplast motions. One can gauge how much light gets through a leaf in land plants. What I just said concerning the top layer(s) of leaves' "palisade parenchyma cells" is accurate. Most of the chloroplasts are found in these cells. Numerous cells in the spongy parenchyma under the palisade layer lack well marked peri and anticlinal walls.
<h2>
How did plant cells incorporate chloroplasts in their DNA?</h2>
Chloroplasts must reproduce in a manner akin to that of some bacterial species, in which the chloroplast DNA is duplicated first, followed by binary fission of the organelle (a kind of protein band that constricts so that two daughter organelles bud off). As a result of some chloroplast DNA actually being integrated into the plant genome (a process known as endosymbiotic gene transfer), it is now controlled in the nucleus of the plant cell itself.
Answer:
It is a mixture
Explanation:
It is a mixture because a mixture contains tow or more elements
But a compound is made up of atoms
Answer:
Blood vessel, a vessel in the human or animal body in which blood circulates. The vessels that carry blood away from the heart are called arteries, and their very small branches are arterioles. Very small branches that collect the blood from the various organs and parts are called venules, and they unite to form veins, which return the blood to the heart. Capillaries are minute thin-walled vessels that connect the arterioles and venules; it is through the capillaries that nutrients and wastes are exchanged between the blood and body tissues.
Explanation:
Answer: State the hypotheses. Every hypothesis test requires the analyst to state a null hypothesis and an alternative hypothesis.
Formulate an analysis plan. The analysis plan describes how to use sample data to accept or reject the null hypothesis.
Analyze sample data.
Interpret the results.
