What are the organelle differences in plant and animal cells
Answer:
Plant cells lack a centrosome and lysosomes, while animal cells do. Animal cells lack a cell wall, chloroplasts, and other specialized plastids, as well as a big central vacuole, but plant cells do.
Explanation:
Photosynthesis is vital for maintaining levels of atmospheric oxygen. Please select the best answer from the choices provided T F.
Photosynthesis is a key determining process to regulate the level of atmospheric oxygen. This statement is true.
What do you mean by Photosynthesis?Photosynthesis may be defined as a process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Without the process of photosynthesis, the evolution of oxygen can not be imagined. Photosynthesis takes carbon dioxide from the atmosphere, and in respect of this oxygen is liberated in our surroundings.
Therefore, Photosynthesis is a key determining process to regulate the level of atmospheric oxygen.

Since forces cause a change in motion or state of a body, friction is a force which opposes motion of an object over another.
What is frictional force?Frictional force or friction is the force that opposes the relative motion of one object over another at their surface of contact.
The two types of friction are:
static friction andkinetic frictionRough surfaces experience the greatest friction while smooty surfaces experience the least friction.
Hence, friction can be reduced by lubrication or polishing.
Based on the property of forces and friction:
Force is defined as a push or pull that starts, stops or changes the direction of a moving object.Friction is a force that opposes motion between two surfaces sticking or touching together.A sandy floor has the greatest frictional force among these surface.Friction is a force that opposes motion. It acts in the opposite direction of a moving object. Friction is a force that occurs when surfaces touch each other. Rolling friction is produced when an object rolls over a surface is produced.Rolling friction is produced when an object is rolled on a surface. Round objects like a Ball produces rolling friction.Riding a bicycle and using of wheelbarrow (kariton) are examples of rolling frictionA soccer ball rolling on the ground is an example of rolling friction.Sliding friction occurs between moving objects and a liquid or between an object moving in the air.Static Friction occurs when there is more force needed to travel an object in a surface than rolling Friction.A train going around its tracks is rolling frictionSliding friction opposes the sliding of objects over a surface.Mucus produced by snails, help them move along the ground because Mucus reduces friction.Therefore, it can be concluded that generally, friction opposes motion of an object over another.

What is one possible result of a mutation within a start codon? A stop codon?
The result of a mutation within a start codon is the non-start of the protein translation, whereas a mutation in the stop codon will long the length of the protein.
What are transcription and translation?Transcription refers to the process by which a fragment of DNA is used as a template to create an RNA molecule, usually a messenger RNA.
Subsequently, this mRNA sequence can be used to create a protein by a process called translation.
The triplets of nucleotides (codons) in the mRNA are read by the ribosomes during translation, thereby a mutation in the start codon would produce a nonfunctional mRNA.
Moreover, a mutation in the stop codon will long the length of the resulting protein sequence.

During _____, the homologous chromosome pairs independently align themselves at the equator of the cell.
Answer:
Prophase I
Explanation:
During prophase I, homologous chromosomes pair up and exchange sections of DNA.
During prophase I, the homologous chromosome pairs independently align themselves at the equator of the cell.
What happens in prophase I?DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent.
Moreover, during prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.
Therefore, during prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures.

Answer: Vegetative propagation is an a s exual method of plant reproduction that occurs in its leaves, roots and stem.
Answer:
VEGETATIVE PROPAGATIONregeneration of new plant from the vegetative part or organ of the parent plant is called vegetative propagation vegetative propagation is used full to separate the plant in wider region mother plant get favourable condition if then colonized to the reason by vegetative propagation the offspring adapted
1 NATURAL VEGETATIVE PROPAGATION-
BY ROOT -
the interact root of several Woody plants such as guava sisoo grow just below the soil produce advantages but should just below the soil produce but should develop from this bird which give rise to new plant
BY STEM -
stamp is the source of natural vegetative reproduction in several plants modification or found in stem to perform vegetative propagation
a Runners- the weak stem of creep forward on the soil that downwardly from node axillary bud are present in the axils of scale leaves node
b s ucker - rise time in similar to runner but it is underground its main stem grow upward and develop advantages root from underground
c offset- the thick and fleshy runner of hydrophytes plant is called offset
BY LEAVES
Titan plant develop adventirious bud on their leaves this word after separating from Mother plant give rise to new plant
BY BULBILS
they are fleshy but which are produced in the axils of leaves in the auxiliary Bud
ARTIFICIAL VEGETATIVE PROPAGATION-GRAFTING
it is the most common method of vegetative reproduction in this method variety of shame spices can be converted into plant of better variety in the technique of trade off to plant are joined in such portion of one part called stock is joint with another plant is called scion
BUDDING-
it is the superior and modern method of plant propagation in this method but of plant are superior varieties grafted in the stem of plant in variety after making oblique you cut up to the bark of stem after fue with this but join with plant as result formed on the new plant
LAYERING-
the method of inductor root formation the branches while they are still attached to a mother plant is called layering
CUTTING -
any part of plant root stem or leaf which has the power to develop itself into a new plant after separating from the mother plant is called cutting
IMPORTANCE OF PROPAGATION
