Should guys with moobs wear bras in public?
Answer: I honestly think it’s all up to the man’s self-esteem and confidence, not the society’s opinions. If he wants to, sure, wear one. If he doesn’t, then he doesn’t have/need to. Personally, wearing something so feminine out in public, if I was a man, would degrade my look even farther on my own masculinity. Therefore, as said before, it’s all up to the mind and values of the person. Hope this helped!

Water are the stages of the water cycle
Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).
Explanation:
A beaker of distilled water was placed on a bench. Using a pipette a drop of red blood cells was placed at the bottom of the beaker Explain why the water in the beaker was uniformly red after 2 hours
Explanation:
when the red blood cells are placed in the water, differences in concentration causes haemolysis to occur at a point,excess pressure in the cell on cell membrane causes the cell to burst, diffusion then takes places causing the molecules of the red blood cells to be distributed evenly throughout the distilled water

Why must organisms continuously acquire energy and materials from the external environment to maintain homeostasis?
Answer:
In order for organisms to sustain all biochemical reactions,and relatively constant internal environments energy must be available in the internal environments.Food substance s are the sources of these energy.They are broken down during cellular respiration and the energy contain is obtain as ATPs.
These (ATPs)are expended for biological work in living organism.Since second law of thermodynamic stated that,in the process of transfer of energy from one form to another,energy is expended as heat.Thus the amount of the heat energy can not be maintain as constant in the organism,
Thus in order to maintain biochemical reactions for biological works continuous source of energy from the external source most be available.
Since the maintenance of constant internal environment of an orgasm is called homeostasis, and this process involved complicated networks fir systems and organs,therefore a constant source of energy for biochemical reactions for this to take place is needed.

What is DNA?Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that tangle into one another to form a double helix that contains genetic instructions for the development, operating, growth, and procreation of all lifeforms and viruses. Nucleic acids include DNA and ribonucleic acid.
Nucleotides are strung together in 2 long strands to form a spiral known as a double helix.
The framework of the double helices is similar to that of a ladder, with the base pairs forming the rungs and the sugar and phosphate molecules forming the ladder's vertical sidepieces.
Thus, the label A is pentose sugar, B is phosphate group, C is phosphate group, D is cytosine, E is adenine, and F is a nucleotide.

Make an inference about what happens to the matter and energy during the formation and breakdown of a complex carbohydrate molecules? When is energy stored or released?
Answer:
The formation or construction of (larger) molecules from smaller chemical units is known as anabolism. Anabolic reactions are energy consuming or endogernic reactions and are the aspect of metabolism that involve building or constructing. For example in photosynthesis reaction, plant combine smaller molecules of carbon dioxide and water, with the absorption of energy from the Sun's to form sugar, as follows;
6CO₂ (g) + 6H₂O (l) [tex]\overset{Energy \ from \ the \ Sun}{\rightarrow}[/tex] C₆H₁₂O₆ (s) + 6O₂ (g)
In the (reverse) process of catabolism, energy is obtained (released) from the breakdown of larger and more complex carbohydrate molecule, which may be through aerobic (involving oxygen) with the release of energy (in the form of ATP)
The cathabolic decomposition of one gram of carbohydrate can yield 4 kcal of energy
C₆H₁₂O₆ → 6CO₂ (g) + 6H₂O (l) + energy
Therefore;
Energy is consumed during building up or formation of larger carbohydrate molecules from smaller ones and
Energy is released when such large carbohydrate molecules are decomposed (broken down) into smaller molecular units
