Answer:
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. The stream of water bends due to the polarity of water molecules.
All the properties of water are related to one another by the polar nature that is caused by the partial electronegativity difference of the hydrogen and oxygen molecules of water molecules.
A water molecule has uneven distribution of charges between different atoms of the different molecules. All types of properties of water due to attractions between these polar molecules.
in water molecules slightly negative atoms of one molecule are attracted to the slightly positive atoms of other moleculesthe attraction forms hydrogen bonding, weak bonds between a hydrogen atom and another atomProperties of water due to polarity and hydrogen bonds:
surface tension - a measure of the force necessary to stretch or break the surface of a liquidcapillary action - the tendency of water to rise in a thin tubecohesion - water attracted to other water moleculesadhesion - Water attracted to other materialshigh specific heat - the amount of the heat that must be absorbed or lost for one gram of the substance to change its temperature by 1°Cexpansion upon freezing - ice is less dense than and on freezing it expands its structure and forms a cage-like structure.Learn more about the properties of water:

A DNA sequence reads: ACAGTCGATGCA. Which of the following is the correct complementary DNA strand?
CACTGATCGTAC
GTGACTAGCATG
TGTCAGCTACGT
UGUCAGCUACGU
Answer:
its C) TGTCAGCTACGT
Answer:
C. TGTCAGCTACGT
Explanation:
In Chargaff's Rule (or the Complementary base pairing rule):
~ Adenine (A) pairs with Thymine (T)
~ Cytosine (C) pairs with Guanine (G)
Because of this rule, with one strand of DNA already having the sequence of ACAGTCGATGCA, The other strand of DNA can only be a sequence that pairs the nitrogenous bases with their assigned pair/base.
Thus, the answer being TGTCAGCTACGT

Identify what is happening to the carbon in the following example: A cow is eating grass.
A. Carbon is being stored through feeding.
B. Carbon is being stored through decay.
C. Carbon is being released through decay.
D. Carbon is being released through feeding.
Answer: b
Explanation:
When a cow is eating grass, the carbon is stored through feeding. Thus, the correct option is A.
How does carbon get stored in the living body?Carbon gets stored in the body through food intake. This follows the principle of biogeochemical cycles that allows the movement of nutrients throughout the environment.
A cow eating grass represents a feeding process through which the cow gets energy for metabolic as well as physical activities.
Therefore, the correct option for this question is A.

identify science vs. pseudoscience ?
Answer:
The big difference Popper identifies between science and pseudo-science is a difference in attitude. While a pseudo-science is set up to look for evidence that supports its claims, Popper says, a science is set up to challenge its claims and look for evidence that might prove it false.

A person pushes a giant boulder with a force of 50N for 10min. The boulder moves 0cm. Use what you know about force, work, and acceleration to explain what happened.
Question 33 options:
500J of work was done because the person pushed for 10 min
The boulder moved 10m because the person pushed for 10 min
The person did a lot of work because s/he pushed with a high force
No work was done because the boulder was not displaced
Answer:
No work was done because the boulder was not displaced.
Explanation:
Even if a person is pushing with a force of 50N and for 10 min, zero work is done and there's no acceleration. Zero work means when the force or displacement on the object is equal to 0 J, and since the boulder never moved it would be 0 J. If the person was pushing with 50 N or even higher and the the object didn't budge, the velocity hasn't changed from rest and that would mean no acceleration occurred.
Which statement best describes DNA’s relationship to a gene and chromosome?
Explain how observation, interpretation, and explanation are important to the study of science.
Answer:
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing.

What are the reactants in the dark reactions ?
Answer: The reactants in a dark reaction are carbon dioxide (CO2) and water (H2O).
Explanation:
Dark reactions are a type of photosynthetic reaction.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Dark reactions occur in the grana of chlorophyll and get energy from ATP and NADPH.
The reactants are carbon dioxide (CO2) and water (H2O).

Which part of plant intake oxygen and give out carbon dioxide?
Any green living plant absorbs carbon dioxide, extracts the carbon and releases the oxygen. The process is called photosynthesis, and is powered by sunlight. The carbon is combined with water and other trace chemicals to form complex organic substances such as starch, wood, etc. On the surface of the leaves of the plants there are a large number of tiny pores known as stomata or stoma. For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells. However, plants only perform photosynthesis in the green parts, like leaves and stems, but all plant cells need oxygen to respire. Cells in the leaves get plenty of oxygen from photosynthesis, but cells in the roots often need to get oxygen from the environment to stay alive.
