I believe that they’re norepinephrine (NE), and the acetylcholine (Ach). Hope this helps!
They separate during meiosis I is true of tetrads.
Explanation:
In Prophase 1, tetrads are formed. Each chromosome has two sister chromatids. When two homologous chromosomes align for crossing over they have four parts and these are termed tetrads.
When homologous chromosome separate tetrads get broken. Tetrads are not present in mitosis because no crossing over takes place in mitosis.
In Anaphase 1 homologous chromosome separate by getting pulled by spindle fibres forming two haploid cells and tetrads get separate.
anabolic respiration
Explanation:
anabolic respiration utalizes eneregy made from catabolic reactions to make complex molecules. these complex molecules are use to form cellular structures.
Answer:
Answer is C.
When a household installs a dual flush toilet, the water is mainly conserved by limiting its consumption and thus eliminates the unnecessary loss of water.
Explanation:
A dual flush toilet is similar to a standard toilet but includes some water conserving features. It is an effective way to reduce the amount of water used in flushing
. It has two buttons to select two different flush settings, one for the liquid waste and the other for solid waste. Normally less water is needed to get rid of liquid waste than solids. Some models of dual flush toilet system reuses the water in the hand washer for flushing. Standard toilets use siphoning action, where a siphoning tube is used to drain the waste. While flushing, a large volume of water enters the toilet bowl which fills the siphon tube and siphon pulls the waste and water down the sewer pipe. The siphoning action stops, when the bowl emptied and air enters the tube producing a gurgling sound. Dual flush toilet has a large hole at the bottom of the bowl and a wash down flushing design to push the waste down into the drain. This system needs less water per flush as no siphoning action is required. Also the waste is easily drained out of the bowl because of the large hole at the bottom of the bowl. In a dual flush toilet, the liquid waste flush utilizes only half the amount of water than the solid waste flush. The main disadvantage of a dual flush toilet is that it is more expensive than a normal toilet..
Answer:However, prior to the Gold King Mine incident EPA’s 2014 Draft Baseline Ecological Risk Assessment (BERA) found that metals emanating from Cement Creek pose severe risks to the aquatic environment for several miles downstream of the mining district. Lesser impairment of the aquatic community is likely to be occurring for at least 30 miles downstream of Silverton.
It is these and other documented environmental impacts that have led EPA to propose the addition of the Bonita Peak Mining District to the National Priorities List (NPL), which is the list of national priorities among the known or threatened releases of hazardous substances, pollutants or contaminants throughout the United States and its territories. By proposing the site to the NPL, additional data will be collected to more fully characterize sources of metals in the Animals River outside of the Cement Creek drainage and to assess risks to human health and the environment.
