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.
What important product or service does the ocean provide that makes all life possible on Earth?
A.
food
B.
tourism
C. transportation
D.
waste disposal
E.

Answer:
E
Explanation:
The ocean is very effective at storing lots of heat and greenhouse gases, and washes the effects of the bad gases away. If it were not for the ocean, more of the ice caps and glaciers would have broken. The ocean provides transportation, but transportation can be done by air as well. The answer is E.

Which phase of meiosis is this cell undergoing?"
Answer:
The correct answer is - Anaphase II.
Explanation:
In the given diagram the single chromatids are attached with spindle fibre and moving towards the different poles, however, the chromosomes divided at centromere that leads to chromosomes to single chromatids.
The anaphase ii stage is known for dividing chromosome and pulling the chromatids towards opposite poles. Thus the given picture represents the anaphase stage of meiosis II.

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).

If there are 200 short plants in the F2 generation from a cross that followed Mendel's methods, about how many plants will be tall in that generation?
Answer:
F2 has 600 tall plants.
Explanation:
According to Mendel's concepts, the F2 generation is formed by crossing two heterozygous plants, that is, two plants with the Aa alleles. These plants have the genes for tall plants and short plants, although they are tall because of the dominant "A" allele. In the cross between these two plants, we will have an offspring formed by 25% of short plants (aa), 25% of hom0zygous tall plants (AA) and 50% of heterozygous tall plants (Aa). As we can see, there are 3 times as many tall plants as short plants in F2's offspring. Therefore, if there are 200 short plants in a population, to know the amount of tall plants, we must multiply this value by 3. By doing this multiplication, we will know that there are 600 tall plants in F2.

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.
Explanation:
Answer:
The hysteria surrounding biological detergents in the UK led to claims that it can lead to or exacerbate such conditions as “erythema, pruritus and eczema.” Despite this, the review finds no evidence of any harmful effects to skin from bio washing powders and detergents
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.
