Which side is hypertonic ? A or B ?
Which side will gain water
What is c ?
Answers
Answer:
1-b
2-b
3-phospholipid bilayer
B side is hypertonic. It will gain water. C is Phospholipid layer.
What is Hypotonic Solution?
A hypotonic solution is a type of solution that has a lower osmotic pressure than any other solution to which it is compared. It is a solution in which a small amount of solute passes across a semipermeable membrane compared to the amount of solute in the other solution.
If the solute concentration outside the cell is lower than inside the cell, these solutes cannot cross the membrane, so the solution is hypotonic to the cell.
The cell membrane consists of a phospholipid bilayer containing embedded proteins present between these two solutions where a hypotonic solution has a relatively low concentration of solutes.
Thus, B side is hypertonic. It will gain water. C is Phospholipid layer.

Two reasons for which viruses have such small genomes include 'viruses have fewer genes than living organisms' and 'viruses have very little non-coding DNA'.
What is the genome?The genome is all the genetic material present in the cells (either somatic or geminal cells) of an organism.
In eukaryotic organisms, the genome is big because it contains many genes required to synthesize different cellular components.Moreover, the eukaryotic genome also contains many non-coding regions, which are laking in smaller simpler genomes.In conclusion, two reasons for which viruses have such small genomes include 'viruses have fewer genes than living organisms' and 'viruses have very little non-coding DNA'.

Compare the population growth rate in industrially developed countries to that in developing countries
Answers
Answer:
The worlds developing regions will see 1.2 billion people added, a 20.7% increase; while the population of developed countries will increase a mere 3.3% adding 41 million to the current 1.3 billion people. ... There is a difference of more than ten years between the median age in developing and developed regions.
The population growth rate in industrially developed countries is much lower than that in developing countries.
The population growth rate is the number of births per 1,000 people in a population in a year. The population growth rate in industrially developed countries is typically around 1%, while the population growth rate in developing countries is typically around 2%.
There are several reasons why the population growth rate is lower in industrially developed countries. First, people in industrially developed countries tend to have fewer children. This is due to a number of factors, including the availability of birth control, the increasing participation of women in the workforce, and the rising cost of raising children.
Second, people in industrially developed countries tend to live longer. This is due to advances in medicine and healthcare. As a result, the number of people in the population who are of childbearing age is lower in industrially developed countries than in developing countries.
The lower population growth rate in industrially developed countries has a number of implications. First, it means that the population in these countries is aging. This is because the number of people who are of working age is shrinking, while the number of people who are retired is growing.
Second, the lower population growth rate means that there is less pressure on resources such as land, water, and food. This can help to reduce poverty and improve the standard of living in these countries.
However, the lower population growth rate also means that there is a smaller pool of workers to support the economy. This can lead to labor shortages and economic problems.
Overall, the lower population growth rate in industrially developed countries has both positive and negative implications. It is important to carefully consider these implications when making policy decisions.

What are the 4 steps of protein synthesis?
Answers
Answer:
In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled.
The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.
Since the DNA cannot leave the nucleus , copies of the section needed to make the protein are made, this is called transcription.
This done by first opening the double helix with an enzyme called DNA Helicase. Another enzyme called RNA polymerase will match new bases to the original DNA attaching them in a long strand of mRNA. When the enzyme reaches the end the strand will be removed and the DNA can close.

Cellular division (Mitosis) is the biological process whereby a parent cell breaks itself into different parts called daughter cells.
This process is important because it helps to divide cells so that they can:
Experience growth Repair broken cells Reproduce, etc
Cellular differentiation is the process of a cell going from one form to a more specialized cell.
A good example of this is the process of a fetus being formed from a single celled zygote.

1. Plant can thrive due to abundant sunlight for photosynthesis and new, nutrient-rich soil made of cyanobacteria and deteriorating rock.
2. Cyanobacteria were the first photosynthesizing organisms and Cyanobacteria lived in the ocean.
3. Oxygen increase weathering leads to formation of soil.
Factors made the land a place where the first land plants could thrive are abundant sunlight for photosynthesis and new, nutrient-rich soil made of cyanobacteria as well as deteriorating of rock.
Cyanobacteria were the first photosynthesizing organisms that lived on Earth 3 billion years ago. Cyanobacteria live anywhere on the earth where light and moisture is available i.e. in the open oceans, lakes and streams, in soils, hot and cold deserts, hot springs and salty water.
Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increase which help in the formation of soil. Oxygen directly take part in the chemical weathering of rocks through the process of oxidation. In this process, oxygen reacts with a substance present in the rock and forms oxides which will result in weathering.

C. Scientists use heat and bacterial
transformation to add novel DNA into bacterial cells.
D. Scientists use high temperatures to separate strands of DNA molecules during polymerase chain reaction.

The statement 'Scientists use restriction enzymes to cut DNA molecules and ligation to paste DNA fragments together' describes the construction of recombinant DNA molecules. This technology is called recombinant DNA.
Recombinant DNA is a genetic engineering approach by which scientists uses specific enzymes to cut and paste nucleotide (DNA) target sequences of interest.
The enzymes that recognize and cut DNA are called restriction enzymes, while enzymes that ligate DNA fragments are called ligase enzymes.
Recombinant nucleotide sequences are placed into specific vectors (e.g., a plasmid) that transport the DNA in a host cell in where this sequence is expressed as protein.

Choose which assumption must be made in order for this estimate of broad-sense heritability to be correct.
a. The phenotypic variance of the genetically identical plants is the same as the genetically variable population.
b. The genetic variance component is strictly the result of additive genetic variance.
c. The environmental variance of the genetically identical plants is the same as that of the genetically variable population.
d. There is no phenotypic variance associated with the environment.
Answers
The assumption 'environmental variance of the genetically identical plants is the same as that of the genetically variable population' is CORRECT. It is used to estimate the variation due to genetic factors.
Heritability (h2) refers to the proportion of the variability of a given phenotypic trait due to genetic factors.
Broad-sense heritability is affected by genetic and environmental factors.
Broad-sense heritability can be estimated as H² = VG/VP, where VG and VP represent genetic variability and phenotypic variability, respectively.
