1. Oxygen (O2)
2. Carbon Dioxide (CO2)
3. Water (H2O)
4. Glucose (C6H12O6)
5. Adenosine Triphosphate (ATP)
Answer:
Active transport; Passive transport; Passive transport
Explanation:
When concentration of a substance is different on either side of a semi-permeable membrane, the movement of this substance can occur by active or passive transport. Active transport occurs when the substance is moved from the region of its lower concentration to that of its higher concentration. This type of movement uses the energy to move the substance. Since the glucose concentration is higher in the epithelial cells than in the food, it will enter into the cells by the process of active transport.
The passive movement of substances is driven by concentration gradient. The glucose concentration is lower in extracellular space than epithelial cells, so glucose will be transported into the extracellular space by passive movement.
Likewise, a higher concentration of glucose in extracellular space than blood will move it passively into the bloodstream.
Answer:
mamals and birds
Explanation:
The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.
Organs are the structures that made up of two or more tissues organized to carry out a particular function.
An organ or bone that appears in different animals with same function is called homologous structure.
Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.
Different animals have bones that appear very similar in form or function and seem to be related.
Examples
The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.
The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job. For example, the wings of bats and birds.
Answer: (x+7)(x-7)
how to get answer:
x^2-49 rewrite as
x^2-7^2
use diff of perf squares: a^2-b^2=(a+b)(a-b)
(a=x, b=7)
fill in the formula of the parenthesis
(x+7)(x-7)
to check you answer is correct, you can foil the answer (x+7)(x-7)
