Cloning ________.
Help, is this the answer? assignment 18. question 8. oh my, did I answer this correctly? wink wink please answer if I did, to post this
Answer:
Cloning removes the nucleus from an egg cell and replace it with the nucleus from another organism.
More information :
The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. The copied material, which has the same genetic makeup as the original, is referred to as a clone.To make a clone, scientists transfer the DNA from an animal's somatic cell into an egg cell that has had its nucleus and DNA removed. The egg develops into an embryo that contains the same genes as the cell donor. Then the embryo is implanted into an adult female's uterus to grow.1. You have 4.0 g of NaCl.

Accept/Reject: Increased parasympathetic impulses to the adrenal medulla would result in cortisol release from neuroendocrine cells to initiate the short-term stress response g
Answer:
Accept.
Explanation:
I accept the statement that increased the impulses of parasympathetic to the adrenal medulla would result in the release of cortisol from neuroendocrine cells to initiate the short-term stress response. The cortisol provides glucose to the body from protein stores through the process of gluconeogenesis in the liver. This energy can help the person to fight against stressor and in avoiding stress. The neuroendocrine system produces the necessary response toward the stress through the secretion of cortisol, which is used to maintain the body's homeostasis.
A biologist is trying to understand the relationship between water and plant growth. She hypothesizes that if she were to give a plant too much water, it would not grow as much. She designs an experiment to test her hypothesis. She plants 2 same-sized plants in the same amount of soil and places them in the same room. She gives Plant A a normal 200 mL of water daily, and gives Plant B a larger 500 mL of water daily. After 1 week, she notices that Plant A grew more than Plant B.
Answer:
The plant A grew better because a water needs normal water but if we put more water to the plants then it will die
how long does it take a 180g sample of radioactive gold (half-life=2.69) to decay to 1/8 its original mass?
It would take approximately 6.27 years for a 180g sample of radioactive gold (with a half-life of 2.69 years) to decay to 1/8 its original mass.
The decay of radioactive gold can be modeled by the equation:
N(t) = N₀ * (1/2)^(t / t₁/₂)
where N(t) is the remaining mass at time t, N₀ is the initial mass, t₁/₂ is the half-life, and t is the elapsed time.
In this case, we want to find the time it takes for a 180g sample of radioactive gold to decay to 1/8 its original mass. This means that the remaining mass (N(t)) is 180g / 8 = 22.5g. We can substitute these values into the equation and solve for t:
22.5g = 180g * (1/2)^(t / 2.69)
Dividing both sides by 180g:
(22.5g / 180g) = (1/2)^(t / 2.69)
Taking the natural logarithm of both sides:
ln(22.5/180) = (t / 2.69) * ln(1/2)
Simplifying:
t = (2.69 / ln(1/2)) * ln(22.5/180)
t ≈ 6.27 years
Therefore, it would take approximately 6.27 years for a 180g sample of radioactive gold (with a half-life of 2.69 years) to decay to 1/8 its original mass.

Stars are burning balls of extremely hot gasses that form when nuclear fusion occurs.
Apparent (how bright they appear ___)
Apparent brightness refers to how bright a star appears to an observer on Earth. It is determined by two factors: intrinsic brightness and distance.
Intrinsic brightness, also known as absolute brightness or luminosity, is a measure of the total amount of light energy a star emits. It depends on the star's size, temperature, and stage of evolution. Intrinsic brightness is typically expressed in terms of the star's luminosity, which is the amount of energy radiated per unit of time.
Distance plays a crucial role in determining the apparent brightness of a star. The further away a star is from Earth, the more its light spreads out over a larger area, resulting in a decrease in apparent brightness. This relationship follows the inverse square law, which states that the apparent brightness of an object is inversely proportional to the square of its distance from the observer.
While stars are indeed burning balls of extremely hot gases that form through nuclear fusion, their apparent brightness can vary depending on their intrinsic brightness and distance from Earth. A star with high intrinsic brightness may appear faint if it is located at a significant distance, while a less intrinsically bright star that is closer to Earth may appear brighter in the night sky.

The relaxed pairing at the third position of the codon and the first position of the anticodon are wobble and able to follow the traditional base pair rules. This allows for a single tRNA to recognize multiple codons.
Relaxed pairing at the third position of the codon and the first position of the anticodon refers to the ability of the genetic code to tolerate non-standard base pairing between these positions during translation. Specifically, the third position of the codon (also known as the wobble position) can form non-Watson-Crick base pairs with the first position of the anticodon, allowing a single tRNA molecule to recognize and bind to multiple codons that differ only in this position. This phenomenon expands the coding capacity of the genetic code and helps to optimize the efficiency of protein synthesis.

Look at the incomplete equation below. What does Ek represent?
In the given equation, Ek represents the kinetic energy of an object.
Kinetic energy (Ek) is a form of energy associated with the motion of an object. It is dependent on both the mass (m) and the velocity (v) of the object.
The equation Ek = (1/2)m\(v^2\) represents the formula to calculate the kinetic energy of an object.
The symbol "Ek" is commonly used to represent kinetic energy in scientific calculations and equations. By plugging in the values of mass and velocity into the equation, one can calculate the amount of kinetic energy possessed by the object.
The kinetic energy of an object increases with both its mass and velocity. As the mass increases, the object has more particles in motion, contributing to higher kinetic energy.
Similarly, as the velocity increases, the speed at which the object moves also increases, resulting in greater kinetic energy.
Therefore, understanding and calculating kinetic energy is important in various scientific and engineering applications, such as studying the movement of objects, analyzing collisions, or designing efficient systems.
