What do you mean by organelle?
Organelles are specialized compartments within a cell that perform specific functions. They are like the organs of a human body, performing a specific task within the cell. Examples of organelles include the nucleus, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex, lysosomes, and peroxisomes.
The cellular surface, or plasma membrane, acts as a barrier between the cytoplasm and the external environment. It also provides structure and organization to the interior of the cell by controlling the movement of molecules, ions, and other particles that enter and exit the cell. The membrane also contains various proteins and lipids that serve as receptors and are involved in signaling pathways that regulate cellular processes. By organizing the interior of the cell, the cellular surface helps to direct the activities of the organelles and ensure that they are located in the right places to function properly.

How long will it take for 40.0 grams of Radium-226 (Ra-226) to decay to leave a total of 2.5 grams of Ra-226? Ra-226 has a half-life of 1600 years.
Answer:
6400 years
Explanation:
Given that;
N/No =(1/2)^t/t1/2
No = amount of radioactive material originally present
N = amount of radioactive material present at time t
t= time taken for N amount of radioactive material to remain
t1/2 = have life of the radioactive material
2.5/40 = (1/2)^t/1600
1/16 = (1/2)^t/1600
(1/2)^4 = (1/2)^t/1600
4 = t/1600
t = 4 * 1600
t = 6400 years

if a plant looses control of its stomata and they remain closed will substances still slow through its phloem
Yes / No
No, if a plant loses control of its stomata and they remain closed, substances will not flow through its phloem.
The stomata are small openings on the surface of plant leaves and stems that regulate the exchange of gases and the loss of water vapor. When the stomata are closed, it restricts the movement of gases, including carbon dioxide, into the plant and the release of oxygen. This closure also limits the transpiration of water from the plant.
The phloem, on the other hand, is responsible for the transport of sugars, nutrients, and other organic molecules within the plant. This transport primarily occurs through a process called translocation, which relies on the pressure gradient created by the movement of sugars from source tissues (such as leaves) to sink tissues (such as roots or developing fruits). Since the stomata play a crucial role in photosynthesis by allowing the entry of carbon dioxide, the closure of stomata will lead to a decrease in photosynthesis and subsequently a decrease in the production of sugars. As a result, the flow of substances through the phloem will be significantly reduced or halted altogether.

Which of the following hormones mainly serves to stimulate milk production by the breasts?
A. thyroid-stimulating hormone
B. follicle-stimulating hormone
C. prolactin
D. adrenocorticotropic hormone
The hormone that mainly serves to stimulate milk production by the breasts is prolactin.
Prolactin is a hormone secreted by the anterior pituitary gland in response to various stimuli, including suckling, as well as during pregnancy. It plays a crucial role in lactation and milk production in mammalian females, including humans.
After childbirth, the levels of prolactin increase, promoting the development of mammary glands and the production of milk. Prolactin acts on the mammary glands, stimulating the synthesis and secretion of milk components, such as lactose, proteins, and lipids. It also promotes the growth of milk-producing cells (alveoli) in the breasts.
While thyroid-stimulating hormone (A), follicle-stimulating hormone (B), and adrenocorticotropic hormone (D) are important hormones involved in various physiological processes, they do not play a direct role in milk production. Prolactin is the primary hormone responsible for stimulating lactation and milk production in the breasts.

Toxins have been tagged to specific types of neurons that will kill specific types of neurons.
These toxins are tagged to specific receptors that are present in the neurons they are meant to target. For example, a toxin called saporin can be tagged to a receptor called the choline acetyltransferase, which is present in certain types of neurons in the brain.
Once the toxin is tagged to the receptor, the receptor binds to the toxin, allowing it to enter the neuron and cause its death. This method of targeting specific types of neurons has enabled us to better understand how neurons interact with each other and how they can be manipulated in order to treat neurological diseases.

Give the equation for standard free energyHow does this differ from the modified standard state?
The equation for standard free energy is ΔG° = -RTln(K), where ΔG° is the change in free energy under standard conditions, R is the gas constant, T is the temperature in Kelvin, and K is the equilibrium constant. The modified standard state takes into account non-standard conditions.
What is standard Gibbs free energy change ΔG?The energy change that takes place as a result of transitioning from reactants to products is known as the standard Gibbs free energy change (Go). When Gorxn is negative and the reaction is exergonic, the products are more stable than the reactants.
Is the Gibbs free energy change ∆ G of a system a state function?The enthalpy of a system less the sum of the system's temperature and entropy is known as the system's Gibbs free energy at any given time. Because it is described in terms of thermodynamic parameters that are state functions, the system's Gibbs free energy is a state function.

O competition
O evolution
O acquired
O overpopulation
Evolution is the term that best describes the change from more light-colored moths to more dark-colored moths. Therefore, option (B) is correct.
What is evolution?Evolution is the process by which different species of living organisms have developed and diversified over time, driven by natural selection, genetic drift, mutation, and other factors, leading to the development of new traits and species.
This process is an example of natural selection, where organisms that are better adapted to their environment are more likely to survive and reproduce, passing their advantageous traits to the next generation. In the case of moths, the increase in the frequency of dark-colored moths was a response to changes in their environment, specifically the industrial revolution and resulting pollution, which made dark-colored moths more difficult to spot by predators, giving them a survival advantage over their light-colored counterparts. Over time, this process resulted in a shift in the population towards darker-colored moths, illustrating the process of evolution through natural selection.
