Answer:
when vesicles cluster at the future plane of division
Explanation:
Cytokinesis is the process whereby the cytoplasm of a cell divides into two. This process of cytokinesis occurs after nuclear division i.e. division of the nucleus. However, cytokinesis differs in plant and animal cells.
In plant cells, the separation of the cytoplasm involves the formation of a cell plate. The process begins when a structure called phragmoplasts carry vesicles to the cell plate. In other words, vesicles cluster at the future plane of division (cell plate).
give two major differences between prokaryotes and eukaryotes
Answer:
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.

HOW DOES THE PROCESS OF TRANSLATION CONVERT INFORMATION
Answer: Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes.
Explanation:
Hope it helps you if not sorry

Answer:
then it may effect the entire biodiversity as many rare animals and birds can be killed and they can be existinc from the nanture it will directly affect the ecosystem and species diversity the food chain will also be directly affected as any one animal or species will be existinc the number of other species may rapidly increases or decrease
A microbiologist discovers a new infectious agent. In an effort to identify the type of agent, the microbiologist exposes the agent to the following: i. RNAse ii. DNAse iii. Protease iv. Heat v. Acid After the different treatments, the microbiologist determines that the agent is destroyed by treatments (i), (iv), or (v). This result leads the scientist to conclude that the agent likely is a(n) _____.
Answer: Viroid.
Explanation:
Microorganisms are those organisms that are very tiny in size and imperceptible to the naked eye. Thus, they are only visible under the microscope. They have a very basic biological organization, a significant proportion of them have only a single cell. Examples are bacteria, archaea (both prokaryotes), protozoa, microscopic fungi and microscopic algae (eukaryotes).
i. RNAases are enzymes of the endonuclease family that catalyze the breaking of ribonucleic acid (RNA) strands by a hydrolytic mechanism. It is present in almost all organisms, from bacteria and archaea to eukaryotes.
ii. DNAases are enzymes that catalyze the cleavage of phosphodiester bonds in deoxyribonucleic acid (DNA). If the enzyme catalyzes the cleavage of the terminal phosphodiester bond it is called exodeoxyribonuclease, whereas if it is an internal bond it is called endodeoxyribonuclease. As the RNAses, they are present in many microorganisms.
iii. Proteases are enzymes that break the peptide bonds found between amino acids of proteins. Proteins are polymers that are found also in almost all microorganisms and perform vital functions such as structural, DNA replication, reproduction, etc.
iv. All microorganisms are affected by heat at a certain degree. The heat causes denaturation of proteins and breaks the cellular membrane.
v. Acids are chemical compounds that release hydrogen ions (H+) in large quantities. They are characterized by being corrosive and they dissociate completely in an aqueous solution. Microorganisms are also susceptible to acids because they denature proteins and affect cell membranes.
If the agent is destroyed by RNAse, heat and acids, it is a viroid.
Viroids are infectious agents that have an extracellular cycle in which they are metabolic inactive, and an intracellular cycle in which they cause infections, like viruses do. However, unlike viruses, viroids have no proteins or lipids and consist of a short, circular RNA strand which does not encode proteins. So they are affected by RNAses but not DNAases. In addition, they have no proteins because they lack a capside and they are not translated into proteins. But like all microorganisms, they are affected by heat and acids (except for some cases of extremophilic bacteria that can withstand high temperatures and/or high levels of acidity).
A glass of milk tips over and the milk spills out into a thin puddle. Why does the milk flow out of the glass instead of staying in its place inside the glass?
Answer:
The milk in the glass is liquid, and takes up the shape of anything that it is in. When the milk spills out of the glass, it loses the shape of the glass.

Athletes require energy to move their body. What biomolecules directly supplies your muscles with quick energy, or ATP, when broken down?
Creatine phosphate directly supplies muscles with quick energy, or ATP, when broken down.
Creatine phosphate is a phosphorylated creatine molecule. Muscles use stored chemical energy from the food we eat and convert it to heat and kinetic energy. Adenosine triphosphate is the source of energy used to power the movement of contraction in working muscles. However, ATP is not stored in large amounts in cells. So once muscle contraction begins, the process of making more ATP starts quickly. The muscle has three biochemical systems to produce more ATP for muscle contraction. One such biochemical system utilizes creatine phosphate. Muscles have a little ATP in them that they can use immediately but it does not last long. So, all muscle cells have a high-energy compound called creatinine phosphate which is broken down to form ATP quickly.

Which level of an energy pyramid is most likely to have the highest number
of organisms?
Answer:
Number of Organisms at the level of producers (First level) is more and hence the availability of energy also will be more at the level of producers. Amount of energy available decreases as we you move from the level of producers to the top carnivores.
Explanation:
First-level producers have more organisms, hence their energy availability is greater. From producers to top predators, energy drops.
What is an energy pyramid?An ecological pyramid is a graphical depiction that is intended to show the biomass or bioproductivity at each trophic level in a particular ecosystem. It does this by inverting the order of the trophic levels.
Food webs are frequently shown as energy pyramids in order to more clearly illustrate how energy moves through ecosystems. Beginning with primary producers at the base of the pyramid, each step of the pyramid represents a different level of the trophic hierarchy. The size of each step is proportional to the amount of energy that passes through that particular trophic level.
The energy pyramid depicts a food chain with four tiers, beginning with producers and ending with carnivores. As a result of the significant amount of energy that is lost along food chains, the energy pyramid, also known as the food chain, typically only has four or five trophic levels.

lizard is a poikilothermic animal why
Answer:
Lizard is a poikilothermic animal because lizards are those animals that do not require a fixed body temperature, their temperatures can fluctuate with little to no adverse effects to their overall health.
Explanation:
Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. By moving in and out of sunlight, reptiles can keep their body temperature at a steady level throughout the day.

What effect do biological washing powders have on the skin?
Answer:
Biological washing powder and liquids contain enzymes. These help to break down fat, grease and proteins to get clothes clean. While enzymes are great for getting rid of stains, they can damage wool, silk and other materials. Many people also find that they aggravate eczema and other sensitive skin conditions.
