how most of our excretory system is not dedicated to excreting; it’s dedicated to reabsorbing.
Answer:
Not all animals use the same routes or excrete their wastes the same way humans do. Excretion applies to metabolic waste products that cross a plasma membrane.
The excretory system works with the respiratory, endocrine, urinary and digestive system. It works with the respiratory system because it helps the lungs get rid of carbon dioxide and water vapors. It works with the digestive system to help get rid of wastes that you eat through the anus.

When there is no pattern to a
population's growth, it is known as
A. irregular
B. stable
C. irruptive
D. cyclical
When there is no pattern to a population's growth, it is known as stable. The correct option is B.
What is population growth?The rise in the number of people on Earth is referred to as population growth. The majority of human history saw a relatively steady population size. Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialisation.
The predicted population expansion is due in part to factors like an increase in young, unmarried mothers, high fertility rates for specific ethnic groups, and a lack of access to contraception and sexual education.
When age-specific fertility and mortality rates are constant over a long period of time, there is a stable population growth.
Contrarily, an irregular population increase is one in which there is no structure and the population size behaves chaotically.
Thus, the correct option is B.

What process can change all three rock types in a new metamorphic rock?
Answer:
The three main rock types are igneous, metamorphic, and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Explain how a carbon atom from a CO2 molecule in the air can end up as a carbon atom in a protein in a plant cell
Answer:
Photosynthesis and metabolism are among the most complex areas in biology so given the nature of this forum I've kept the answers simple and brief.
Carbon is of central importance to all biological systems due to its special bonding properties allowing it to form various bonds with other atoms and produce a wonderfully complex range of molecules used by life.
In photosynthesis inorganic carbon in carbon dioxide gas is fixed to hydrogen to produce sugar, an organic molecule. In this case the carbon gains electrons so it is 'reduced' and this process requires energy in the form of light. Once in sugar form, the process can be reversed and the carbon can be oxidised back into carbon dioxide during cellular respiration, releasing energy.
So in photosynthesis, the carbon from carbon dioxide is reduced to form a sugar molecule. When transitioning to respiration, the carbon in the sugar is oxidised to form carbon dioxide again in the reverse reaction to photosynthesis.
The carbon is transferred between molecules through various intermediate steps during these processes, involving enzymes (biological catalysts) to assist in cleaving specific bonds at each stage. During cellular respiration (an energy release reaction) as the carbon is successively oxidised electrons are liberated that are used as part of the energy release. These electrons are captured or 'carried' by special organic molecules called NAD and FAD (reducing them) which in turn can then be oxidised to produce the universal energy currency of life: ATP molecules. ATP is a small bio molecule containing a high energy phosphorous bond that can be broken to release energy to do cellular work. It is used by all life that we know of and is the ultimate product of cellular respiration.
The carbon atom in a CO₂ molecule in the air can become a part of the
cellulose molecule in a plant by the carbon dioxide molecule reacting with the water during photosynthesis to form Glucose.
This formula can use for the reaction: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
The glucose molecule formed is then translocated to other parts of the
plants which are such as the roots and stems and help in the formation of cellulose.
Also, aThis is basically how the carbon atom in carbon dioxide becomes a cellulose molecule.Learn more about:

Tendrá la intensidad de la luz un efecto en la velocidad de la fotosíntesis, cuando los períodos de exposición están limitados a la duración normal de la luz para una planta
Answer:
ver explicacion
Explanation:
La fotosíntesis es el proceso mediante el cual las plantas verdes fabrican su propio alimento en presencia de luz solar, clorofila, dióxido de carbono y agua.
La intensidad de la luz afecta la tasa de fotosíntesis, cuanto mayor es la intensidad de la luz, mayor es la tasa de fotosíntesis y viceversa. Cuando hay una mayor intensidad de luz, hay más luz disponible para impulsar las reacciones de la fotosíntesis.

how magnification and resolution affect the appearance of objects viewed under a microscope
Answer:
It allows to see objects more clearly.
Explanation:
Magnification and resolution greatly affects the appearance of objects that can be seen under a microscope because these two things make the specimen enlarge in size. Magnification refer to the process of enlarging the apparent size of something to see and observe it clearly while on the other hand, resolution is used to see more details about specimen that can be study in the microscope so we can conclude that both magnification and resolution has a great impact on the appearance of objects.
What is the volume of a square pyramid with a base edge of 14 m and a slant height of 25 m
Answer:
length of base(l) = 14m
slant height (s)=25m
we know,
slant height(s)=√(l/2)^2 + h^2
or, 25= √(14/2)^2+ h^2
or, 25 = √49+h^2
or, 25^2 = 49+h^2
or, 625 = 49 + h^2
or, 625-49=h^2
or, √576 =h
h=24
Therefore vertical height (h)= 24m
Again,
Volume of square pyramid (v) = 1/3 L^2h
or, v =( 1/3) 14^2×24
or, v= 4704 / 3
Therefore, V= 1568 cubic meter.
