Katyanochek1 [597]3 years ago
4 0

Meiosis makes sperm and eggs. ... The result is 4 haploid daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes – 1 from each pair in the diploid cell). At conception, an egg cell and a sperm cell combine to form a zygote (46 chromosomes or 23 pairs).

HOPE THIS HELPS AND GOOD LUCK

A blood hemoglobin measurement of 13.5 g/100 ml would be which level of measurement?
balandron [24]

A blood hemoglobin measurement of 13.5 g/100 ml would be a normal level of measurement.

Hemoglobin is a protein in red blood cells that transports oxygen. How much hemoglobin is in your blood is determined by the haemoglobin test? The most significant part of red blood cells is hemoglobin. It is made up of heme, a protein that binds oxygen. Adults typically achieve a range of outcomes, but in general: Male: 138–172 grams per liter (g/L) or 13.8–17.2 grams per deciliter (g/dL). Women: 121–151 g/L or 12.1–15.1 g/dL. The nominal level of measurement is the first measurement level. The variables' numbers are only used to categorize the data at this level of measurement. Words, characters, and alphanumeric symbols can all be employed at this level of measurement.

Explain how heat can be a source of water pollution.
Fiesta28 [93]
Heat is considered as a water pollutant because it decreases the capacity of water to dissolve oxygen, and it increases the rate of metabolism fish. Valuable species of game fish cannot survive in water with very low levels of dissolved oxygen.

How is enthalpy used to predict whether a reaction is endothermic or exothermic?
Radda [10]

<u>Answer:</u>

<em>329.48 KJ/mol heat is released by the combustion of 2 molof methane</em>

<u>Explanation:</u>

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)

\Delta H \ reaction=[ 2(\Delta HfCO_2)+ 4(\Delta HfH_2O)]-[2(\Delta HfCH_4)+4(\Delta HfO_2)]

                            =2 ( -(393.5 KJ)/mol)-[2( -74.6 KJ/mol)+4(-241.82 KJ/mol)]

                            = -787 KJ/mol-[ -149.2 KJ/mol-967.28 KJ/mol]

                           = -787 KJ/mol+1116.48 KJ/mol

                                          =329.48 KJ/mol

<em>In this question, </em><em>the enthalpy of formation</em><em> has positive value and hence the </em><em>reaction is endothermic</em><em> in which the heat is released. </em>
