In water and ice, the slightly ______ hydrogen atoms in one water molecule are drawn to the slightly _______ oxygen atom in another water molecule.
A. positive, negative
B. negative, positive
C. neutral, positive
D. neutral, negative
Answer:
option c
Explanation:
The water molecule is a polar substance that has partially charged ions. The hydrogen atom is partially positive, whereas the oxygen atom is partially negative in charge. Thus, option A is correct.
What is polarity?The polarity of the molecule is defined by the presence of the electrical charges over the elemental atom that results in the formation of the chemical bonds by the electrostatic forces.
Water is an example of a polar molecule that is linked by a covalent bond by sharing the electrons between the oxygen and the hydrogen atom of the molecule.
The hydrogen atom is said to have a partial positive charge and oxygen has a partial negative charge because of the uneven electron density. The electronegative oxygen pulls the hydrogen towards it.
Therefore, option A. hydrogen is partially positive and oxygen is partially negative.

Some villagers plan to remove the trees from this hillside.
Doing this could damage their environment.
a ) Suggest one immediate problem for the animals that live on the hill.
b ) Suggest one problem that could arise during the rainy season.
Answer:
1) Deforestation has real consequences for animals. The most serious impacts of deforestation on animals are listed below. #1 Habitat loss Deforestation can lead to a direct loss of wildlife habitat as well as a general degradation of their habitat.
2)When there is less soil stability because of the disadvantage of erosion, the risk of a flooding event occurring during the rainy season increases dramatically. Poor water absorption levels make it easier for higher accumulation levels since the trees are no longer present to take up the extra moisture.

difference between diabetes mellitus and diuresis?? please help
Explanation:
If you have been in EMS long enough, you may well have encountered a patient with diabetes insipidus. Like many, you may have assumed that it is a variant of the common disease diabetes mellitus. Actually, diabetes mellitus and diabetes insipidus are totally unrelated other than the name. The term diabetes is derived from Latin (originally Greek) and means “to go through or siphon,” referring to a large amount of urine produced by the kidneys. The term melitus, in Latin, means “sweet.”

Why is The sun is the ultimate source of energy
for all living organisms.'
Answer:
"Sun is the ultimate energy source for all living organisms."
✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.
✴Secondly, sunlight is a good source of Vitamin-D.
Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.
✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.

What are muscle cells?A muscle cell exists also known as a myocyte when directed to either a cardiac muscle cell or a smooth muscle cell as these exist both small cells. A skeletal muscle cell exists long and threadlike with many nuclei and is named a muscle fiber. Muscle cells originate from embryonic precursor cells named myoblasts.
The muscle cells exist as a specialized kind of cell (one of the four tissues) that can contract to exert action.
These cells (muscle cells) can be paralyzed by utilizing various inhibitors of movement such as poisons.
In conclusion, the cells in the prey that exist most likely affected by the poison present in the darts exist the muscle cells.

PLSSS HELPP- Study the qualities below. Which unit of measure is being described? • used to measure length • smaller than a meter O centimeter 0 kilometer 0 hectometer O dekameter
Answer:
centimeter
Explanation:
Description:
used to measure lengthsmaller than a meterAll answer choices are units that are used to measure length so the first hint isn't much help.
The only unit listed that is smaller than a meter is a centimeter so the answer would be centimeter.
1 Centimeter = 0.01 Meter
( If it helps to remember centi means one hundredth, so centimeter means one hundredth of a meter )
centimeter is the lowest standard unit of measure the length.
What Is standard unit of measurement of length?The product of speed and time can be represented as distance.
d=s×t, where d is the distance m, t is the time taken to cover s
s is the speed in m.s-1
Different units can be used to measure Length like centimeters, inches, meters, it can be classified into two types such as Standard units of measuring length and non-standard units of measuring length.
Standard Units of Measuring Length include the pre-defined such as If two measure the length of the same object using any standard unit will get the same result.
standard units of length are measured in the form of meters, centimeters, inches, feet. It can be up two types such as Imperial units and metric system units.
Imperial System is based on existing units, examples are nautical mile, mile, rod, inch etc.
Metric units are kilometer, hectometer, decameter, meter, centimeter, and millimeter etc.

H20fall, how do I find out how much salt is in my pool?
A very peculiar question, kind sir
I supposed one can start by allowing his pool water to evaporate in the blazing summer heat in order to separate the solute (salt) from the solvent (water). After the separation, the obtained mass of salt can be measured on a scale in order to determine the concentration of salt that is present within thy swimming pool. This technique is the most classic of all, and is also the most expedient way to extract salt from water.
