ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.
Answer:
A
Explanation:
the sister chromatids separate
After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.
What is Homologous pair?Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.
In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.
This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.
Therefore, the correct option for this question is A.

Bile juice dose not contain any digestive enzymes yet it is essential for digestion why so ?explain
Explanation:
Although bile juice does not contain any enzymes, it contains bilirubin and biliverdin. These help to break big fat globules into small globules which is taken to pancreatic juices to be further digested. This is known as emulsification of fat. It also helps in secretion of lipase. Thus it plays an important role because majority of the fat digestion process is carried out by it.

After phosphates and nitrates have entered a water
system, identify the correct steps of Eutrophication.
I. Oxygen levels drop
II. Underwater plants die
III. Fish and invertebrates die
IV. Algae grows rapidly
A. II, III, IV, I
B. IV, II, I, III
C. I, III, IV, II
D. III, II, I, IV
After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
Algal bloom: the nutrients facilitate the rapid growth of algaeThe bloom of algal species results in the death of underwater plants as a result of inadequate light.The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxiaTherefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

Fomites are Group of answer choices insects that transmit pathogens from an infected host to a non infected host. animal sources for human pathogens. inanimate objects involved in the indirect contact transmission of pathogens. fecal material from infected hosts. silent carriers of infectious diseases.
Answer:
Fomites are inanimate objects involved in the indirect contact transmission of pathogens.
Explanation:
Fomites are inanimate objects involved in the indirect contact transmission of pathogens. These objects include a whole range of items mostly found in indoor environments. When pathogens such as viruses and bacteria come in contact with these objects through various human and animal activities such as sneezing or coughing, use of toilets etc; these pathogens remain active on these objects and can then cause disease when others come in contact with these objects.
Common fomites in the home include toilet seats and handles, doorknobs, kitchentops, bed coverings , mobile phones, light switches as well as as toys. In offices, door handles, stairway railings as well as wring materials are common fomites. Especially concerning is the issue of disease transmission by fomites in healthcare facilities since there is constant exposure of surfaces and equipments to various pathogens.
To help prevent the spread of diseases by fomites, regular handwashing and disinfection of commonly touched surfaces is required.

A student finds that the mass of 25mL of an unknown liquid is 20.5g. What is the density of this substance?
Answer:
Density, [tex]d=0.82\ g/cm^3[/tex]
Explanation:
It is given that,
Mass of unknown liquid is 20.5 kg
Volume, V = 25 mL
We know that, 1 mL = 1 cm³
25 mL = 25 cm³
The density of the substance is equal to its mass per unit volume. So,
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{20.5\ g}{25\ cm^3}\\\\d=0.82\ g/cm^3[/tex]
So, the density of this substance is [tex]0.82\ g/cm^3[/tex].

Explanation:
Please write down prearation of perment slides of pollen grains by acetolysis method and study of different pollen characters: study of variation pattern in different taxa.
Answer is given below
Explanation:
Collection and preservation of pollen material: In clean glass pots containing 70% glacial acetic acid, some of the stamens are applied with clean forceps prior to flower synthesis and sometimes protected from diamonds or mature flower buds. Some polyologists recommend 70% ethyl alcohol to preserve feathers in place of glacial acetic acid. In this condition, pollen-filled feathers can be stored indefinitely. The wings are transferred to a centrifuge tube and rinsed well with distilled water.the wings are crushed with a glass rod and the mixture is filtered through a cheesecloth or sieve. The lower part is recalled in the centrifuge tube. A freshly prepared acetolysis mixture containing acetic anhydride and concentrated H2SO4 (sulfuric acid) in a ratio of 9: 1 is poured into a centrifuge tube containing the washed pollen. Care must be taken to connect the conceider. H2SO4 by acetic anhydride drop to prevent overheating. The acetolysis solution reacts violently with water. Glacial acetic acid washers are required to replace water with acetic acid, which does not react violently with the acetolysis solution. Although the acetolysis process varies from pathologist to pulmonologist, the following approach seems to be the most appropriate. From the first to the last acetic acid wash, care is taken regardless of the water solution. Only distilled water should be used for washing to prevent contamination.Dose anyone know the answer
