I see half of it and what are you working on?
Answer: Osteoclasts are the bone cells that break down bone.
Explanation:
Answer:
A sewing needle floats when it is placed gently on top of water in a bucket - surface tension
Water molecules ding to plant cell walls - adhesion
A water strider runs across a pond without breaking the surface - surface tension
A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface - cohesion
Water molecules cling to the side of a beaker - adhesion
Water molecules are attracted to each other - cohesion
Explanation:
The surface tension refers to the tendency of the surface of a liquid to remain unbroken by an external force due to the cohesive property of the molecules of the liquid. Instead of being broken, the surface of the liquid stretches like an elastic membrane.
The adhesive property of a liquid, also known as the force of adhesion, refers to the property of the molecules of the liquid to stick to other molecules while cohesive property or cohesion refers to the property of molecules of liquids to stick to themselves.
Hence,
<u>Surface tension</u>
- A sewing needle floats when it is placed gently on top of water in a bucket.
- A water strider runs across a pond without breaking the surface.
<u>Cohesion</u>
- A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface.
- Water molecules are attracted to each other.
<u>Adhesion</u>
- Water molecules ding to plant cell walls
- Water molecules cling to the side of a beaker
Answer:
make up genes and chromosomes
Explanation:
Darwin is known for his theory of evolution which explained how the organism evolved on the planet and the Mendel is known for his explanation that how the traits are passed on to the generation.
But both were unaware of this that the factors which control the traits are composed of DNA.
The DNA was discovered in 1869 in the nucleus of the white blood cells but it was not established that the genetic material is the DNA as it was discovered later in 1944. The later studies on the DNA showed that the DNA forms the genes which control the trait and are present on the chromosomes.
Thus, makeup genes and chromosomes is correct.
1.mitokondria
2.chloroplasty (because it is a plant cell according to the figure)
3. endoplasmic reticulum (1-smooth and 2-granular)
4. Golgi apparatus
5.Ribozomi
6. lysosomes
