EXPLAIN VEGETATIVE PROPAGATION IN PLANTS AND ALSO MENTION THEIR ADVANTAGES AND DISADVANTAGES.
Answer:
Advantages and Disadvantages of Vegetative Propagation
ADVANTAGES
Faster and more certain method of propagation.
New individuals produced have exactly identical qualities as their parents. This preserves the characteristics of food and flower crops.
Can be used to reproduce plants that do not have viable seeds.
The flowers produced are of a superior quality.
Certain desirable characteristics present in the fruit can be maintained.
DISADVANTAGES
Does not produce new varieties
Leads to over crowding
Very little dispersal

sometimes during their orbits, the moon &’ the earth form a line with the sun. when this happens, an eclipse occurs. there are two kinds of eclipse- lunar &’ solar. can you identify them? identify each eclipse seen here. then match the descriptions to the correct term/phrase.
Answer:
The pic on the right is a solar eclipse and the one on the left is a lunar eclipse. Lunar eclipse only happens when the sun and moon are directly aligned in front of the sun. A lunar eclipse occurs when the Moon moves into the Earth's shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned with Earth between the other two, and only on the night of a full moon.
Hope this helped, have a good day!

You only need one dominant gene to have?
Answer:
Dominance is not inherent to an allele or its traits (phenotype). It is a strictly relative effect between two alleles of a given gene of any function; one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth.

5.) What are 3 cell structures that both prokaryotes and eukaryotes have? What is the function of each structure?
6.) What two molecules is the cell membrane mostly made of?
8.) What is homeostasis? How does the cell membrane help the cell to maintain homeostasis?
9.) In all forms of passive transport, molecules always move from an area of _____ concentration to an area of ____ concentration. (fill in the blanks)
10.) What is the difference between diffusion and osmosis?
11.) What is the difference between passive transport and active transport?
Answer:
Explanation:
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment
Cell membranes are composed of proteins and lipids. Since they are made up of mostly lipids, only certain substances can move through. Phospholipids are the most abundant type of lipid found in the membrane. Phospholipids are made up of two layers, the outer and inner layers.
One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. Cells are suspended in a fluid environment. Even the cell membrane is fluid. ... By allowing some materials but not others to enter the cell, the cell membrane acts as a gatekeeper.
The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes. Substances diffuse from areas of high concentration to areas of lower concentration; this process continues until the substance is evenly distributed in a system.
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand, passive transport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy

10.) Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
11.) While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules. It could be as simple as molecules moving freely such as osmosis or diffusion.

Cellular respiration takes place in...
A. the food vacuole
B. the lysosome
C. the mitochondria
Describe the relationship between photosynthesis and cell respiration.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Because the image below is showing 4 chromosomes lined up together in one line. that is Metaphase in the process of mitosis as added in the diagram below!
Answer:
Mitosis!
Explanation:
Mitosis is the phase of the cell cycle where chromosomes in the nucleus are evenly divided between two cells. When the cell division process is complete, two daughter cells with identical genetic material are produced.

Why do plant cells have larger vacuoles than animal cells?
__________________________________________________________
OPTION A i.e. Plants have to store more water for structure and support
__________________________________________________________
The plant has the large vacuole than animal cell because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to give plant structural support. The vacuole provide rigidity and firmness to the plants cell whereas in animal cell rigidity is not required so the vacuole are many and small. The membrane of vacuoles in plants is called tonoplast which is used mainly in regulating the movements of ions around the cell, and isolating materials that might be harmful or a threat to the cell.
_____________________________________Best Regards,
"Borz"
Plants have to store more water for structure and support. Therefore option A is correct.
Plant cells have larger vacuoles than animal cells because plants require a significant amount of water for various essential functions.
Vacuoles in plant cells serve as water reservoirs, allowing the plant to store and maintain water, which is crucial for providing structural support, rigidity, and turgor pressure.
Turgor pressure is essential for maintaining the shape and stiffness of plant cells, enabling the plant to stand upright and support its weight.
In contrast, animal cells do not require such extensive water storage for structure and support, as animals have different mechanisms for maintaining their shape and movement through muscles and bones.
Therefore option A Plants have to store more water for structure and support is correct.

how is matter transformed in cellular respiration
Answer:
matter is converted from carbon dioxide and water into glucose.energy is converted from light to chemical energy.
Explanation:
Energy is transferred as matter is broken down into simpler molecules and some energy is converted and released as heat
Answer:
Rather, the matter of the reactants of cellular respiration are transformed into the matter of the products of the reaction. During cellular respiration, one glucose and six oxygen gas molecules produce six water compounds, six carbon dioxide compounds, and energy in the form of adenosine triphosphate (ATP).

Explain the role of valence electrons and how they relate to the periodic table of elements?
Plz this i really need to finish this.
Explanation:
The valence electrons determine the group the elements belong in the periodic table. For example, the element sodium, Na, has a valence electron of one and so it belongs to Group 1 in the periodic table. Another example is Aluminium, Al, which has a valence electron of three and therefore it belongs to Group 3 in the periodic table.
