Specific gravity indicates the amount of dissolved substances in the urine.
What is urine?As it travels through the nephrons and down the renal tubules of the kidney, urea, along with water and other waste products, creates the urine. both ureters. From the kidneys to the bladder, urine travels through these tiny tubes. The excretory organs remove some additional, frequently poisonous compounds from the circulatory fluids and expel them from the body through urine, which is a liquid or semisolid solution of metabolic wastes. Urine often reflects an organism's needs for water in terms of composition.
What is specific gravity?The difference between an object's density and that of a standard substance is its specific gravity. Depending on its value, the specific gravity might indicate whether an object will float or sink in our reference substance. A laboratory test called urine specific gravity reveals the concentration of all chemical particles in the urine.
Thus from above conclusion we can say that specific gravity indicates the amount of dissolved substances in the urine.

7. how are the nadph and g3p molecules made during photosynthesis similar? 8. they are both end products of photosynthesis.
Both NADPH and glyceraldehyde-3-phosphate (G3P or GA3P) molecules use chemical bonds to store energy.
The process of photosynthesis is utilized by plants and other living things to change light energy into chemical energy that may then be released through cellular respiration to power the organism's activities.
The initial stage of photosynthesis results in the production of NADPH. The processes that take place during the second stage of photosynthesis are aided by it. For the many phases of the photosynthetic process to be completed, plant cells need light energy, water, and carbon dioxide.
Sunlight, carbon dioxide, and water are the three substrates needed for photosynthesis, which is a multi-step process. It generates glyceraldehyde-3-phosphate (G3P or GA3P), a simple carbohydrate with a high energy content that may be transformed into glucose, sucrose, or other sugar molecules, as well as oxygen.

Interspecific relations support hypotheses and conclusions about how species like trees within a forest at a particular successional stage can drive/govern/control succession.
The relationship between one species and another inside a community has advanced through their intelligence, based on the prerequisite and the mode of sustenance and protection additionally on the propensities of species.
The connections between individuals of distinctive populaces are named interspecific relations.
Competitive intelligence between woodland trees is driven by species’ characteristic pecking order, not phylogenetic or utilitarian likeness: suggestions for woodland community assembly.

green plants use light from the sun to drive photosynthesis. photosynthesis is a chemical reaction in which water and carbon dioxide chemically react to form the simple sugar glucose and oxygen gas .what mass of simple sugar glucose is produced by the reaction of of carbon dioxide?be sure your answer has the correct number of significant digits.
13.27g mass of simple sugar glucose is produced by the reaction of 7.96 g of water.
since the chemical equation for photosynthesis is:
6CO₂+6H₂O→C₆H₁₂O₆+6O₂
from the equation, there are 6 moles of carbon dioxide which reacts with 6 moles of water to form 6 moles of oxygen and 1 mole of glucose sugar. Since we know the molar mass of water is 18.01 g/mol.For 7.96g of moles of water will be :
nH₂O = 7.96/18.01g⋅mol−1
=0.442mol
From the reaction we get to there is the production of 1 mole of glucose from 6 moles of water, by the reaction of 0.442 moles of water, the number of moles of sugar formed is :
nC₆H₁₂O₆= (1molC₆H₁₂O/6molH₂O )X0.442molH₂O
= 0.074mol
Since the molar mass of glucose is 180.16 g/mol, so the mass of the simple sugar is

placentals and marsupials are two groups of mammals. placentals are more closely related to each other than they are to any other group of animals, and marsupials are more closely related to each other than they are to any other group of animals. placental wolves look very similar to marsupial wolves. if you use distance analysis of morphological traits to build a phylogenetic tree that includes humans (a placental mammal), placental wolves, and marsupial wolves, which two groups would you conclude are most closely related? would the tree be correct?
Due to convergent evolution placental mammals (Wolf) are closely related to marsupial wolves (Tasmanian wolf). No, the tree is wrong.
What is convergent evolution?
It is the presence of similar features in animals of different lineages. The structures in these animals have similar functions but are absent in the common ancestors hence they are analogous structures not homologous.
Such convergence of functional, morphological, and structural traits from phylogenetically unrelated species may be a result of random mutation due to selection pressure.
Here, the Tasmanian wolf (marsupial wolf) and wolf (placental mammal) have several morphological similarities but they have unrelated ancestral lineages. Hence they show convergent evolution. These two subclasses of mammals have adapted to a specific food source, locomotor ability, or environment in similar ways.
Hence, the placental wolf and Tasmanian wolf exist sharing the same habitat in different continents former in Asia and the latter in Australia because these two show convergent evolution.

He had come to a conclusion by 1855 that all living things evolve. But what he couldn’t figure out was how. Three years later he figured it out when he was on an island, sick with fever: he concluded that animals evolve by adapting to their environments.
After his discovery, he wrote down his theory in an 8-9 page paper, and sent it to Charles Darwin. Darwin reached the same conclusion a couple of years later and the two men then published a paper together (1858), arguing about the theory of natural selection and evolution.

What is solidification process?
Atoms are transformed from a liquid, disordered state through the process of solidification into an ordered solid state. By adhering to the kinetic principles, the conversion rate for the solidification process can be attained.The unique structure of a water molecule is made up of one oxygen atom and two hydrogen atoms. The peculiar arrangement of these atoms gives water certain unusual features, including its high thermal conductivity, surface tension, adhesion, and cohesion.When water freezes, the molecules get organized into a crystalline structure and take on a certain shape. Since there are spaces between individual molecules in this less dense crystalline structure, water expands as the volume of the structure as a whole rises.Ice forms as water expands, and because volume is inversely proportional to density, ice is less dense than water. This is the reason why ice, which feels heavier in its solid state than in its liquid one, floats on water.
Thus when water changes to ice its volume increases and density decreases.
