Answer:The structure and functions of cells that found in the video include:
Explanation:
1. Nucleus:
Structure=it is a spherical body which is covered by a double membrane which contains hereditary materials.
Functions= it controls all life activities of the cell. It stores hereditary information as it contains DNA.
2. Mitochondria:
Structure: They are oval or rod shaped and bounded by a double membrane
Functions: They are site of cellular respiration.
3. Ribosomes:
Structure: They are small round bodies attached to endoplasmic reticulum.
Functions: They are responsible for protein synthesis.
4. Endoplasmic reticulum:
Structure: They are membrane-like structure that forms channel within the cytoplasm.
Functions: they aid transport of materials within the cytoplasm.
Golgi bodies:
Structure: They are series of disc-shaped sacs.
Functions: They function in synthesis, packaging and distribution of materials within the cell.
2. Types of cell present in kidney
-messangial cell
- Loop of Henle
-podocytes
Answer:
When we compare the feeding of larvae with royal jelly to raise queen bees with turning off the Dnmt3 gene
It can be said that the latter is more effective in terms of the number of queens that can be produced and the energy expenditure is much lower. Well, keep in mind that bee larvae only become queens when they receive large amounts of royal jelly. A royal jelly protein is what activates the mechanisms to be a queen bee, this jelly machinery the nurse worker bees.
Through genetic manipulation, the Dnmt3 gene can be turned off in any larva to produce a queen bee.
The characteristics that separate plants from fungi include:
1. plants have chlorophyll and can produces their own food while fungi live off others and they cannot produce their own food.
2. Plants reproduce through seeds and pollen, fungi reproduce through spores.
3. Plants have root systems, stem and leaves whereas fungi only have filaments which attach to the host.
4. Plants are producers while fungi are decomposers.
5. The cell wall on plants are made of cellulose, while those of fungi are made of chitin.
The Hubble Telescope is used for the observation of stars and galaxies that are far away from the universe and also for viewing the planets in our solar system.
<u>Explanation:</u>
It was 1990 when, the Hubble Space Telescope was launched. It mainly aims in the observation of the universe and the place from where the elements that make up the space has emerged. After the discovery in 1990, the observations made by this is about 1.3 million.
It is considered to one of the most important and a useful instrument that has been discovered. It only revolves around the earth and takes the images of stars,planets and other galaxies without reaching them. The mechanism of optics and detectors that more sensitive in nature are attached to this instrument.
