Explain why green chilies are preserved using vinegar and sugar.
Answer:
The solution in which the whole green chillies are soaked is a mixture of vinegar and water. The reason why green chillies are kept in this solution for long hours is to reduce the heat of the spice. Doing so will not only reduce the spiciness of the chillies, but will also add a tangy flavour to them.

Which of these happens to astronauts in space without the pull of gravity?
A
Their vertebrae spread out.
B
They cannot eat solid food.
C
They shrink a few inches.
D
Their hair all falls out.
Answer:A
Explanation: I looked it up
Astronaut's vertebrae spread out in space without the pull of gravity.
What do you mean by pull of gravity?Gravity is a force that attracts all objects towards each other – every object with mass pulls on every other object with mass. When a person jumps off a chair, the person is attracted to the Earth and the Earth is attracted to the person.
The average gravitational pull of the Earth is 9.8 meters per second squared (m/s2). The Earth is made of different substances like air, rock, and water. These substances have a different amount of mass in a certain amount of space (density).
The measure of the pull of gravity on an object is called weight. For an object to have weight it must have mass. Weight can be calculated on Earth by multiplying the mass of an object in kilograms by the acceleration of gravity, which is 9.8 m/s2.

Answer:
thymine
Explanation:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 protein stoichiometry ratio (base pair rule) of purine and pyrimidine bases (i.e., A+G=T+C) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
How is your body temperature held constant?
The elasticity of those capillaries plays a central role in our ability to maintain constant body temperatures. When there's too much heat in the body, our capillaries automatically expand and increase the blood flow to the skin, allowing the excess heat to transfer to the air.

In dogs, spotty fur is a recessive trait. Show a cross between two dogs that are heterozygous for spotty fur. What is the likelihood of these dogs having puppies with spotty fur?
Answer:
The correct answer is - 25% chances of having puppies with spotty fur.
Explanation:
In this question, it is given that spotty fur is a recessive character which means in the heterozygous condition it is not expressed in the phenotype. Here the cross between two heterozygous dogs for spotty fur will produce the following gametes:
Heterozygous: S and s where S is dominant allele and s is the allele for spotty fur that is recessive
Punnett square:
S s
S SS Ss
s Ss ss
By the Punnett square, we can say that likelihood of spotty fur (ss) in puppies is only 1/4 or 25%.

What is the action force and the reaction force when someone swims?
No link
Answer:
The action and reaction forces are reciprocal (opposite) on an object. The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward. The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
Explanation:
Answer:
the force is push and the reaction is moving forward.

A virus has wiped out the grasshopper population in the area. What effects to the ecosystem will most likely occur?
Answer:
Those who prey on grasshoppers will have their population decline while the grass population will rise.
Explanation:
Organisms need food to survive. If their food is gone, they won’t thrive as well. This isn’t saying they’ll go extinct, as they may have other food sources, but life will be harder with one food source gone. Since grasshoppers eat grass, the grass population will rise some due to a lack of predation. Hope it helps :)
Which of the following mutations would most likely be passed along to an organism's
offspring?
A. Mutation that occur during crossing over during the prophase stage of mitosis
B. Mutations that occur in both DNA strands synthesize do the S-phase of mitotic cell cycle
C. Mutations that involve translocation of chromosomes in gametes
during meiosis
D. Mutations that occur in Somatic cells During cell division
Mutations that involve the translocation of chromosomes in gametes during meiosis are likely to be passed to offspring (Option C). It is because mutations are inherited from germinal cells.
Mutations and MeiosisMeiosis is a cell division by which a cell produces four daughter germinal cells having half of the genetic material.
Moreover, a mutation is any alteration in the genetic material of the genome of an organism.
Germinal mutations can be inherited because they occur in the germinal meiotic cells, whereas mitotic (somatic) cells are not inherited.

Answer:
6. Current = 8.33 Amps
7. Energy = 1200 Joules
Explanation:
Given the following data;
6. Power = 1000 Watts
Voltage = 120 Volts
To find the current flowing through;
Power = current * voltage
1000 = current * 120
Current = 1000/120
Current = 8.33 Amps
7. Power = 900 Watts
Time = 45 minutes to hours = 45/60 = 0.75 hours
To find the energy consumption;
Energy = power/time
Energy = 900/0.75
Energy = 1200 Joules
The Competitive Exclusion Principle states that: Group of answer choices a. When two species occur together, competition is always prevented by some behavioral adjustment. b. Two species that use a limited resource in the same way cannot coexist indefinitely. c. Two species that use the same community can use limited resources in different ways. d. When two species each compete for the same resource in the same location, competition will always evolve into commensalism. e. None of the choices are correct.
Answer:
b. Two species that use a limited resource in the same way cannot coexist indefinitely
Explanation:
The competitive exclusion principle establishes that two or more species that share the same niche requirements, in the same habitat, and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. This is because species with identical niches have the same necessities, which means that they will compete for the same resources. If these species have the same requirements, they can not coexist. When the superior competitor occupies the inferior competitor´s fundamental niche, the first species has advantages over the second species and monopolizes all the resources. From that moment, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs or get extinct.
When two competing species coexist, this is because of niche partitioning or niche differentiation. One of the species uses a different resource, occupies another area, or uses the resources at different times during the day. If there is not any differentiation between them, the dominant species displaces the weak species.
Niche specialization might produce genotypic separation. Subpopulations of a species diverge into new species.
So, competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche.
Answer:
B. Two species that use a limited resource in the same way cannot coexist indefinitely.
Explanation:
The Competitive Exclusion Principle states that: Two species that use a limited resource in the same way cannot coexist indefinitely.
