Bones and cartilage are connective tissues’ prove this with evidences.
Answer:
hope it helps : )
Explanation:
Cartilage and Bone are specialized forms of connective tissue.
They are both made up of cells embedded in an extracellular matrix.
It is the nature of the matrix that defines the properties of these connective tissues.
Cartilage is thin, avascular, flexible and resistant to compressive forces.
Bone is highly vascularized, and its calcified matrix makes it very strong.

Erik remembered that his
science teacher had told him that an explosion in space could not really be heard. Why
is this so?
Answer:
Because space is a vacuum, gases released into space expand very quickly, and as they expand their density decreases. So say you were in a spaceship in the middle of a big space battle and a nearby ship exploded. The exploding ship would release gases and technically sound could travel along with them

system starting with the heart and ending with the heart.
Since there are no constructive (volcanic activity) or destructive (erosion) forces at work under the ocean, the ocean floor is flat.
True
False
False so false
Ik it cant be true because there are underwater volcanoes and the earths plates are constantly moving.

Why do most plants appear green?
Answer:
Most plants appear green because they absorb all other colors of light and reflect back green into our eyes. Since chlorophyll molecules use the red (opposite of green) end of the visible light spectrum to complete photosynthesis, then red is most heavily absorbed.
Chlorophyll gives plants their green color because it does not absorb the green wavelength of white light which is the light wavelength reflected from the plant, so it appears green.
What is Chlorophyll?The green color of many plants and algae is due to chlorophyll. Chlorophyll is defined as concentrated within organisms in structures called chloroplasts.
It is the green pigment in plants, algae and cyanobacteria that is essential for photosynthesis. The central structure is an aromatic porphyrin or chlorinated porphyrin ring system with a chelated magnesium atom.
Chlorophyll is formed in several different forms where chlorophyll a and b are the major types found in higher plants and green algae; Chlorophylls c and d are found mainly with a in various algae while the Chlorophyll e is a rare type found in some golden algae and bacterio-chlorophyll is present in some bacteria.
Thus, Chlorophyll gives plants their green color because it does not absorb the green wavelength of white light which is the light wavelength reflected from the plant, so it appears green.

What type of boundary is depicted in the image below?
a. transform
b. collisional
C. convergent
d. divergent
Please select the best answer from the choices provided
Answer:
B-Collisional
Explanation:
Collisional boundary is the type of boundary depicted in the image below and is denoted as option B.
What is Collisional boundary?
This boundary occurs when two land masses meet and they crush together to form fragments.
The image shows the land masses being together and crushing which is why collisional boundary was chosen.

Calorie is a unit of Energy Energy stored in chemical bonds are used by compounds to power cell activities like ATP Equation summarizing cellular respiration is ; 6O₂ + C₆H₁₂O₆ -----> 6CO₂ + 6H₂O + EnergyMost of the Energy would be lost in the form of light and Heat Cellular respiration begins with Glycolysis which takes place in Cytoplasm Equation summarizing photosynthesis is ; 6CO₂ + 6H₂0 + (energy) -----> C₆H₁₂O₆ + 6O₂. Cellular respiration continues in the mitochondria of the cell with the Electron transport chain.Paths requiring oxygen in cellular respiration are Aerobic . Paths that do not require oxygen are AnaerobicCellular respiration is made of three(3) metabolic pathways which are grouped into two categories ( Aerobic and Anaerobic ). The metabolic pathways are : glycolysis, Citric cycle, and electron transport chain.
Glycolysis is an anaerobic process because it does not require oxygen while The citric cycle and glycolysis are aerobic processes which requires oxygen. while Calorie is simply a unit of energy
