Why do Earth’s crust remain the same size despite sea floor spreading?
A. Older rocks eventually disintegrate on the ocean floor.
B. As new rocks are formed along mid-ocean ridges, older rocks are pushed down deep into the Earth into ocean trenches.
C. Hot magma dissolves all the old rock near the eruption site.
D. None of these choices are correct.
Answer:
B. As new rocks are formed along mid-ocean ridges, older rocks are pushed down deep into the Earth into ocean trenches.
Why is the Earth not getting larger if the sea floor is slowly spreading?Mainly due to the Atlantic experiencing seabed expansion. The sea bottom is subducting, or moving underground, in the Pacific. This is how the Earth's tectonic plates and geological activities function. The top side of the mantle travels to the bottom at one end and to the top at the other, similar to a conveyor belt. This explains why there are volcanoes, why continents drift, and why our planet's surface is continually changing over the span of millions of years.
Therefore, the planet is not getting bigger because its surface is constantly recycling itself.
What are the precautions of asthma
Asthma is basically a bronchial infection in which the bronchi actually swells and whenever, mucus gets deposit in bronchi it creates problem in breathing which leads to a asthmatic attack. It is considered as a universal chronic disease. As it lasts for a long span of time if not cured at early age. In modern science there is no medication discovered to cure it permanently. However, some drugs has been introduced which provide temporary relief.
Asthma can be cured by following these simple steps:-
1.Yoga and regular exercise :- Yoga and physical exercises helps a lot to overcome from breathing problems . Pranayams such as Anilom-Vilom and Kapaalbhati are considered as the best yoga exercises for asthmatic patient. About 30 to 45 min of daily yoga can bring a magical change.
2.Precaution's and Prevention's :-
• Keep yourself away from dusty places.
• Fried and spicy food should be avoided.
• Avoid cold places such as AC rooms.
• Don't eat foods creating mucus, such as curd, rice etc.
• Take light dinner about 2 to 2.5 hours before going to bed.
3.Have faith in yourself :- The last but the most important thing required to cure asthma is your faith in yourself. You must have faith and patience. It looks funny that faith can cure a disease but it's a real truth. There is a quote for faith that
“Faith can move mountains”
It means faith have so much of power that it can move even mountains. But here, we have to fight with a simple disease which is extremely easy.

Place a check mark next to each star that is only fusing hydrogen into helium at this time.
The stars that are only fusing hydrogen into helium at this time are :
Star 1 Star 2 and Star 3 Characteristic of a star fusing hydrogen into heliumA star fusing hydrogen into helium is categorised as a main sequence star. As a star continues to fuse hydrogen into helium, energy is released in the process and the luminosity of the star increases as well. An example of a star that has completely fused hydrogen into helium is the sun. A giant red star signifies that the star is out of hydrogen it uses for nuclear fusion.
Hence we can conclude that the stars undergoing hydrogen fusion into helium are stars 1, 2 and 3

In what way could you increase the rate of the reaction as it taking place in image C?
add more enzyme
add more substrate
remove substrate
remove enzymes
remove product
Answer:
Add more enzymes
Explanation:
the purpose of enzymes in nature is to increase the rate of chemical reactions inside an organism
Enzymes increases the rate of a reaction. In the given image, the enzyme molecules are not sufficient to combine with that much substrates thus more enzymes have to be added. Hence option A is correct.
What are enzymes?Enzymes are bio-catalysts which catalyses almost all biological reactions in living organisms. Catalysts are substances which increases the rate of a chemical or biochemical reaction without direct involvement and change by itself.
Catalysts helps to attain equilibrium in a reaction faster by decreasing the activation energy of the reactants. Activation energy is the minimum amount of energy required to overcome the potential barrier in a reaction.
An enzyme have a pocket like cavity into which a substrate places properly. The substrate binds with the cavity and forms an enzyme-substrate complex. This complex then forms a transition compound or an intermediate product which then forms a enzyme-product complex.
Enzyme then release the product. Thus enzymes provide a smooth surface for the reactions to take place. Hence by increasing enzyme amount appropriate to the substrate amount the reaction rate increases.

Rudolph the Reindeer has a red nose (n), which is a recessive trait. Betsy the Reindeer has a black nose (N), which is a dominant trait, and she does not carry the recessive allele. Assume the rules of human genetics also apply to reindeer.
A. Either NN or Nn
B. Nn
C. NN
D. nn
Answer: black, black, black, red
Explanation:
If there is a dominant allele present, any recessive alleles are ignored and the reindeer displays the trait associated with the dominant allele.
Therefore A, B, and C have black noses because they have 1 or more dominant alleles
D has two recessive alleles so it displays the recessive trait.
Hope this helps.
Answer:
B. Nn
Explanation:
We know Betsy does not have recessive allele which means she is a homozygous dominant, NN. Rudolph has a red nose which is recessive trait, to get a recessive trait you need to be homozyogus recessive, nn.
Now, if you cross NN x nn (assuming you know how to do punnet squares), all the offsprings will be Nn (black nosed)

Answer:
While the adult carp prefer slow moving water, they look for high, fast moving water when laying eggs (spawning). They lay hundreds of thousands of eggs at a time, which means populations grow and spread quickly. Because of this, they can quickly out-compete native species, and put ecosystems in danger.Carp are also thought to lower water quality, which can kill off sensitive organisms like native freshwater mussels.Asian carp cause serious damage to the native fish populations in the lakes and rivers that they infest because they out-compete other fish (video, 1 min) for food and space.

formed from the original codon pattern?
The amino acids formed from the codon in the Mutation are different from those formed from the original codon pattern, not because after the mutation the sequencing is changed, giving rise to different codons.
What is a DNA mutation?Mutations are abnormal changes in the DNA of a gene. The building blocks of DNA are called bases. The sequence of these bases determines the gene and its function. Mutations involve changes in the arrangement of the bases that make up a gene.
How many amino acids make up a codon?Degenerate/Redundancy: There are four nitrogenous bases that make up DNA and RNA. They are arranged in triplets, forming codons. Thus, there are 64 different codons that correspond to the twenty amino acids that make up proteins. Therefore, more than one codon corresponds to the same amino acid.
With this information, we can conclude that the amino acids formed from the codon in the Mutation are different from those formed from the original codon pattern, not because after the mutation the sequencing is changed, giving rise to different codons.

Ecosystems change when all of the above components listed change ie, living components of an ecosystem, nonliving components of an ecosystem, or their stability is disrupted.
Hence correct option is D.
A community of creatures and their physical environment make up an ecosystem.Ecosystems can be terrestrial, aquatic, or marine and come in a variety of sizes. The term "biome" refers to broad classifications of terrestrial ecosystems. Ecosystems, the dynamic network of living and nonliving things in a place, change gradually over time. New plants and animals either thrive or suffer when they are introduced to a region. Sometimes thriving species suppress native species. The system as a whole starts to shift when this occurs.If the living components i.e., flora and fauna of the ecosystem change then there will be increase or decrease in food availability and either surge in predators or no predators at all. hence it will greatly affect the ecosystem.non living components such as temperature, water availability, natural calamities can also affect the ecosystem. it can lead to extinction or migration from one place while influx of immigration to another.if the stability of ecosystem is disrupted due to change in living and non living components then also the ecosystem will be affected.hence all of the above options are correct.
