What does a body cell undergo?

Chap wanted to see if planting seeds deeper into the soil had an effect on plant height. He took ten containers and planted radi

zvonat [6]

Answer:

Independent variable: Planting depths of seeds

Dependent variable: plant height

Explanation:

Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.

Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.

In cats, there are two types of ears: normal and curly. A curly-eared cat mated with a normal- eared cat, and all of the kittens

sp2606 [1]

Answer:

In cats, there are two types of ears: normal and curly. A curly-eared cat mated with a normal- eared cat, and all of the kittens had curly ears. Are curly ears a dominant or recessive trait? Explain.

CC x cc = Cc, Cc, Cc, and Cc 4:0

All kittens have curly ears, this is as a result of the dominance of curly ears to normal ears that is recessive

Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?

oee [108]

Given what we know about the translation process, we can confirm that the RNA in question that aids in the process of translating a short sequence of RNA into an amino acid is mRNA.

mRNA is referred to as messenger RNA. This RNA molecule acts as just that, a messenger carrying the necessary code to create amino acids and therefore, proteins. This messenger binds itself to the ribosomes of a cell, which are in charge of reading the code, one codon at a time, and chaining together the corresponding amino acids.

Arrange the steps in the correct order to explain how a muscle fiber contracts

Law Incorporation [45]

Step 1A nerve impulse moves down and axon and causes the release of acetylcholine.
Step 2Acetylecholine causes the pulse to spread across the surface of the sarcolemma.
Step 3The nerve impulse enters the T Tubules and Sarcoplasmic Reticulum, which stimulates the release of calcium ions.
Step 4Calcium ions combine with troponin, shifting troponin and exposure of the myosin binding sites to the stock.
Step 5ATP breaks ADP + P. The released energy activates the myosin crossings and leads to the slipping of thin stockmilofilament past the thick myosin membrane membranes.
Step 6The sliding of the myofilaments draws the Z lines, the sarcoma shortens, the muscle fiber contract and thus muscle contracts.
Step 7ACh is activated by acetylcholinesterase, which inhibits the nerve impulse conduction across the sarcolemma.
Step 8Nerve impulse is inhibited, calcium ions are actively traced back into the Sarcoplasmic Reticulum, using the energy of the previous ATP degradation.
Step 9The low calcium concentration causes the myosin crossings to separate from the think-in-tensile filaments and return the stockmilofilaments to their relaxed position.
Step 10Sarcomeres return to their rest lengths, relax muscle fibers and relax the muscles.

Gravity is the force that objects exert on each other because of their masses. The strength of the gravitational force between t

LuckyWell [14K]

If one of the masses is doubled, the force of gravity between the objects is doubled.

As distance between the objects increases, the force of gravity decreases.

Greater mass results in greater force

Explanation:

Gravity is related to mass and distance as proposed by the newton's law of universal gravitation.

The law states that "the gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional the the square of the distances between them. ".

Mathematically we have:

F ∝ m₁ m₂

F ∝ $\frac{1}{r^{2} }$

m is the mass of the body

r is the distance between them.

We can simply understand that the greater the mass, the greater the force.

Also the higher the distance between the objects, the lesser the force of gravity between them.

Now, ;

F = $\frac{G m_{1} m_{2} }{r^{2} }$

if the mass is double the force becomes doubled too.

if m₁ = 2m₁

F₁ = $\frac{G m_{1} m_{2} }{r^{2} }$

F₂ = $\frac{G 2m_{1} m_{2} }{r^{2} }$

equation F₁ and F₂, we can see that F₂ is twice F₁
