The point mutation can alter the amount of DNA sequences depending upon the type of mutation.

A point mutation is a type of mutation in which the DNA or RNA, the organism's genetic material, is altered by the addition, deletion, or modification of a single nucleotide base. The amount of DNA is unaffected by base substitution since the nucleotide count is unaffected after the substitution. The amount of DNA grows with insertions and mutations because there are more nucleotides involved, whereas it decreases with deletion mutations. A common example of substitution point mutation is sickle cell anemia.

Hence, the type of point mutation determines the amount of DNA.

Answer:

Though humans and mouse looks very different from each other but they have lot of similarity in their genes.

If a mouse is injected with human genes, it tell that how the DNA structure in mouse and humans are similar and genes carry out related functions.

When the human gene will inject into mouse, if the genes functions properly and do not show any alteration in function, it means DNA structure is similar in both organisms.

Answer:

the process of turning from liquid into vapour

Answer:

Evaporation is a surface phenomenon, which implies that the process only occurs at the surface of the liquid. During evaporation, the molecules of the liquid that are present at its surface overcome the intermolecular forces of attraction to break away from the liquid and escape into the atmosphere as a gas (or vapour).

Very salty water is the environment where extreme halophiles are found. Halophiles include a number of bacterial and eukaryotic organisms, the majority of which are members of the class Archaea.

An extremeophile who can survive in salty environments is referred to as a "halophile," which is Greek for "salt-loving." Examples include the alga Dunaliella salina and the fungus Wallemia ichthyophaga. Some well-known species, most notably bacteriorhodopsin, exude red-colored carotenoid molecules. Halophiles can be found in saltier water bodies besides the ocean, such as the Dead Sea, Urmia Lake in Iran, the Great Salt Lake in Utah, and Owens Lake in California. They can also be found in evaporation ponds.

Burning fossil fuels, cutting down forests and farming livestock are the main factors of global warming

Explanation:

for further explanation

2011-2020 was the warmest decade recorded, with global average temperature reaching 1.1°C above pre-industrial levels in 2019. Human-induced global warming is presently increasing at a rate of 0.2°C per decade.

An increase of 2°C compared to the temperature in pre-industrial times is associated with serious negative impacts on to the natural environment and human health and wellbeing, including a much higher risk that dangerous and possibly catastrophic changes in the global environment will occur.

For this reason, the international community has recognised the need to keep warming well below 2°C and pursue efforts to limit it to 1.5°C.

Greenhouse gases

causes_greenhouse_gases

The main driver of climate change is the greenhouse effect. Some gases in the Earth's atmosphere act a bit like the glass in a greenhouse, trapping the sun's heat and stopping it from leaking back into space and causing global warming.

Many of these greenhouse gases occur naturally, but human activities are increasing the concentrations of some of them in the atmosphere, in particular:

carbon dioxide (CO2)

methane

nitrous oxide

fluorinated gases

CO2 produced by human activities is the largest contributor to global warming. By 2020, its concentration in the atmosphere had risen to 48% above its pre-industrial level (before 1750).

Other greenhouse gases are emitted by human activities in smaller quantities. Methane is a more powerful greenhouse gas than CO2, but has a shorter atmospheric lifetime. Nitrous oxide, like CO2, is a long-lived greenhouse gas that accumulates in the atmosphere over decades to centuries. Non-greenhouse gas pollutants, including aerosols like soot, have different warming and cooling effects and are also associated with other issues such as poor air quality.

Natural causes, such as changes in solar radiation or volcanic activity are estimated to have contributed less than plus or minus 0.1°C to total warming between 1890 and 2010.

" Scientists have used genes from spiders to genetically engineer goats that produce silk strands along with their milk".

The answer is Spider silk proteins can now be produced in large quantities without killing spiders to obtain them.

Explanation:

The procedure in this question is describing genetic engineering/modification, which involves manipulating the genome of an organism in order to obtain desirable traits. In this case, certain genes from spiders have been used to genetically modify goats, which now produce silk strands along with their milk.

This process means that silk proteins, which is naturally produced by spiders, can now be produced in large quantities without having to kill spiders to get it since it will nor be produced alongside milk by GM goats.

Daniela wanted to figure out what type of liquid worked best for growing beans. She watered one with coca-cola, one with lemonade, and one with just water. After one week, she measured how high they had grown. What is the independent variable?

Answer: An independent variable is a variable that does not depend on any other variable (it is the input variable) while a dependent variable is a variable that depends on other variable (it is the output variable).

In this question the two variables are the height of the plant after a week and the type of liquid used. Since the height of the beans depend on the type of liquid, therefore the height of the beans is the dependent variable while the type of liquid is the independent variable.

A lesion formed by the buildup of sebum and keratin in a hair follicle is known as a comedo.

When excess sebum the comedo occurs, which is an oily substance produced by the sebaceous glands, and keratin, a protein found in skin and hair cells, accumulate within a hair follicle. This accumulation forms a plug, which can either be open or closed. An open comedo, commonly referred to as a blackhead, has a dark surface due to the oxidation of sebum and keratin exposed to air.

A closed comedo, or a whitehead, has a small white bump on the skin's surface, as the follicle opening is blocked by skin cells. Comedones are often associated with acne, a skin condition that affects many individuals and can lead to inflammation and scarring if not properly managed.

The amygdala is a brain structure that plays an important role in emotional and instinctual reactions.

The amygdala is an almond-shaped structure that lies in the temporal lobe, lying just beneath the uncus. The amygdala is diverse and complex in structure and comprises approximately 13 nuclei. They further subdivide into extensive internuclear and intranuclear connections. The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli. When a person feels stressed or afraid, the amygdala releases stress hormones that prepare the body to fight the threat or flee from the danger.

It is most likely that people who were able to produce a detectable antibody response also express MHC class II allotypes that bind efficiently to the 12 amino acid peptide expressed by the bacteria.

MHC Class II allotypes (also known as MHC alleles) are variations in the genetic code that lead to different forms of the MHC Class II molecule. They are responsible for presenting peptides (antigens) from pathogens (bacteria, viruses, etc.) to T cells of the immune system.MHC Class II molecules have two chains: alpha and beta. MHC Class II allotypes are due to differences in the genes that encode for these chains. They are highly polymorphic, meaning that there are many different versions of the genes that encode them.It has been found that the C57BL/6 strain of laboratory mice, after being given non-pathogenic bacteria that have been engineered to express a 12 amino acid peptide, produces IgG antibodies that neutralize IAV.

It has been determined that MHC Class II molecules are required to present the 12 amino acid peptide to T cells. As a result, it is likely that humans who express MHC Class II allotypes that are efficient at binding to the 12 amino acid peptide expressed by the bacteria will also produce detectable antibody responses.
