Answer: Eukaryotes are more evolved than prokaryotes. This is false. Again, no living taxon is more evolved than another.
Sometimes you might not be able to see a new substance forming, so be on the lookout for evidence that a chemical change has occurred. A change in smell and color can indicate that a new substance has formed. For example, caramelized onions have a very different smell than raw onions. They have a darker color, too. Other physical properties about the onions change during caramelization, including their texture. The formation of bubbles can be evidence of a chemical change, but only if they indicate that a new gas is formed. If you heat a pot of water, the water will begin to boil. Those bubbles are not any new substance forming. They’re just the same water you started with changing state from liquid to gas.
Based on this passage, if you cannot see that a new substance has formed,
A
only a physical change could have occurred.
B
a chemical change might have occurred.
C
a change in state has always occurred.
D
no change could have occurred.
it is possible for a chemical change to occur even if there is no visible evidence of a new substance forming.
What visual signs of chemical alteration exist?A change in colour and the appearance of bubbles are two indications of a chemical shift. The five elements of chemical change are: colour change, precipitate or gas production, gas formation, odour change, and temperature change.
If there is no chemical change, may a physical change still happen?Physical changes can be brought about by physical actions like adjusting the temperature or pressure. You melted the ice, but nothing happened chemically. Water molecules are still molecules of water.

land areas they flow past because they
a. earthquakes on, stimulate tectonic plates
b. streams on, carry extra water onto the land
c. climates of, carry warmer or colder water great distances
d. rock formations on, prevent erosion
Answer:
c. climates of, carry warmer or colder water great distances.
Explanation:
Surface currents in the ocean can affect the temperature of the surrounding air and land areas they flow past, influencing regional climates. Warm ocean currents can bring warmer and more humid weather to the adjacent land, while cold ocean currents can have the opposite effect, cooling the air and land temperatures. This can have significant effects on local ecosystems, agriculture, and economies.

ThanksHope it helpsWhy is it necessary for a cells to have nucleus acids in its nucleus
It is necessary for cells to have nucleus acids in their nucleus because they carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.
A nucleic acid is a chain of nucleotides that biological systems use to store genetic information. It produces the DNA and RNA molecules, which hold the data necessary for cells to produce proteins.
A "polymer" of "nucleotides," or a long molecule made up of them, is referred to as nucleic acid. All life on Earth needs nucleic acids to store genetic information; in other words, nucleic acids serve as the "source code" or fundamental blueprint for the creation of cells.
Your genetic information, which you acquired from your parents, is stored and transmitted by nucleic acids. Genes are unique pieces of nucleic acids that are in charge of creating every protein in your body.

2 characteristics of egg of honey be
A honeybee queen lays eggs that are hexagonal in shape. The eggs of a honeybee are of a rice grain size fertilized eggs become the females while the unfertilized eggs become drones.
The honeybees vary slightly in color but are generally brown with bands of dull yellow and brown on the abdomen. Hair is abundant on the head, thorax, and abdomen. The legs and eyes are covered in hair. They live in large colonies led by a single queen.
By the third day, the egg is laid upright and falls to the side. The queen bee will lay both a fertilized egg and a non-fertilized egg, and the fertilized egg will develop into a female bee or queen bee. The non-fertilized egg will hatch and a male bee is born, also known as a drone bee.

II) Scattering small quantities of poison along exterior of restaurant
III) Trapping pests in mechanical devices and releasing them far from the restaurant
A) I only
B) I and II only
C) I and III only
D) I, II, and III
I'm pretty sure its either C or D, but I don't know if the use of poison in II. invalidates IPM or not.
Explanation:
The strategy that would likely be part of a system of integrated pest management in a restaurant kitchen is option C) I and III only.
Integrated Pest Management (IPM) is a sustainable approach to managing pests that combines multiple strategies to minimize the use of chemical pesticides. It involves identifying and eliminating the root causes of pest problems by using a combination of cultural, physical, biological, and chemical control methods.
Sealing cracks in walls and placing screens over windows is a cultural and physical control method that can prevent pests from entering the restaurant. Trapping pests in mechanical devices and releasing them far from the restaurant is a biological control method that can be used to capture and remove pests without killing them. Scattering small quantities of poison along the exterior of the restaurant is a chemical control method and not a part of the IPM approach.
Therefore, options A, B, and D are not correct, and the correct answer is option C) I and III only.

similarities between plant growth and animal growth
\(\textbf{Question:-}\)
=>Similarities between plant growth and animal growth.
\(\textbf{Answer:-}\)
Similarities between plant growth and animal growth are as follows:-
Both plants as well as animals need sun's energy for their growth.Both of them depend on water for proper development.Both are made up of cell.When body temp increases it causes
metabolic reactions to increase, which
releases heat that further increases body
temp. This is an example of
a. Homeostasis
b. Positive feedback
c. Negative feedback
d. All of the above
When body temp increases it causes metabolic reactions to increase, which releases heat that further increases body temp. This is an example of positive feedback.
Positive feedback is a process in which a change in a system leads to an amplified or increased response in the same direction as the initial change, rather than stabilizing the system as negative feedback does. In positive feedback, the output enhances or reinforces the original stimulus, leading to a cascading effect of the process, which can be beneficial or detrimental to the system depending on the context.
Positive feedback loops can be found in various biological processes, such as blood clotting, childbirth, and action potentials in neurons, and can also be observed in non-biological systems, such as climate change and population growth.

PEP + ADP → Pyruvate + ATP ∆G = -14.8 kcal/mol
ATP + H2O → ADP + Pi ∆G = -7.3 kcal/mol
Glutamic acid + NH3 → Glutamine ∆G = +3.4 kcal/mol
Which reactions can be coupled?
Reactions can be coupled if the products of one reaction are reactants in the other reaction, and if the overall ∆G of the coupled reactions is negative. Therefore, reaction 3 (Glutamic acid + NH3 → Glutamine) is the non-spontaneous reaction among the given reactions.
We can see that in this instance, the first two processes involve the interconversion of ADP and ATP and have negative G values. As a result, they are both exergonic, or processes that release energy.
These two reactions can therefore be coupled because the first reaction's energy discharge can be used to fuel the second reaction.
The third process, on the other hand, produces glutamine from glutamic acid and ammonia and has a positive G value. This indicates that it is an endergonic process, which uses up energy.
This reaction therefore cannot be coupled immediately to either of the first two reactions. Therefore the reaction 3 is correct.

How many half-lives have passed when there are three times as much daughter isotope as parent isotope?
When the ratio of daughter to parent isotope is three, there have been three half-lives.
What is meant by isotope?The same element's isotopes are different nuclear species. The periodic table shows that they are in the same place and have the same atomic number, but the number of neutrons in their nuclei causes their nucleons to differ. An isotope is one of two or more species of atoms of a chemical element having the same atomic number and location in the periodic table and virtually identical chemical behaviour but with distinct atomic weights and physical characteristics.Carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238 are a few radioactive isotopes as examples. Numerous isotopes have half-lives that are known to be exceedingly lengthy (in the hundreds of millions of years).
