the discovery of isotopes disprove one part of
Dalton's atomic theory
Answer: Because Daltons theory states all atoms of a given element are identical in mass and properties.
Explanation:
The discovery of isotopes demonstrated that atoms of the same element can have different atomic weights, implying that atoms of the same element are not identical in every way.
What is Dalton's atomic theory?Dalton's atomic theory postulated that matter is made up of indivisible particles known as atoms, and that atoms of the same element are all identical and cannot be created or destroyed.
Compounds are formed by the simple combination of atoms into compound atoms.
Dalton, John Experiments with gases became possible at the turn of the nineteenth century, prompting John Dalton to propose a modern theory of the atom based on certain assumptions.
Dalton's theory is debunked. This is because Dalton's theory states that all matter is made up of identical, indivisible, and indestructible atoms. Isotopes have the same element but a different number of neutrons.
Thus, this way, the discovery of isotopes disprove one part of Dalton's atomic theory.

Which of the following is NOT true of enzyme activity? a. enzyme shape may change during catalysis b. the active site on an enzyme orients its substrate molecules, therby promoting interaction of their reactive parts c. all enzymes have an active site where substrates are temporarily bound d. each enzyme can catalyze a wide variety of different reactions
Answer:
D. Each enzyme can catalyze a wide variety of different reactions
Explanation:
Each enzyme can only catalyze a few, specific types of reactions.
Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.
If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.
So, each enzyme can only assist in a few reactions.
The correct answer is D. Each enzyme can catalyze a wide variety of different reactions
Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all three types of solutions (hypertonic, hypotonic, and isotonic).
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.More about osmosis here: https://brainly.in/question/1213189

The hormone oxytocin is released to increase contractions during childbirth, and the pathway is activated with pressure from the baby's head against the opening of the uterus, so it is a positive feedback because the response intensifies the original stimulus that is present in the third option.
What is the importance of the hormone oxytocin in childbirth?Oxytocin, a hormone that plays an important role in the process of childbirth, is produced in the posterior pituitary during labor, and oxytocin is responsible for stimulating contractions of the uterus, which help to push the baby through the wall of the uterus. Oxytocin makes the bond between a mother and her newborn baby, as it is released in large amounts during childbirth and breastfeeding and helps to create a strong emotional bond.
Hence, the hormone oxytocin is released to increase contractions during childbirth, and the pathway is activated with pressure from the baby's head against the opening of the uterus, so it is a positive feedback because the response intensifies the original stimulus that is present in the third option.

Monosaccharides, fatty acids, nucleotides and amino acids are all monomers used to build macromolecules. Monosaccharides are the building blocks to which macromolecule?
DNA
Carbohydrates
Proteins
Lipids
Answer:
Carbohydrates
Explanation:
Fatty acids are building blocks of lipids
Nucleotides are building blocks of DNA
Amino acids are building blocks of protiens
Monosaccharides are building blocks of carbs
Monosaccharides are the building blocks to carbohydrates. The correct option is B.
The constituent parts of monosaccharides are what make up carbs. Carbon, hydrogen, and oxygen make up the macromolecules known as carbohydrates in the ratio of 1:2:1.
Simple sugars like glucose and fructose are monosaccharides, which can combine through dehydration synthesis to create bigger carbohydrate molecules.
In addition to serving as an essential source of energy for living things, carbohydrates also function as structural support for things like plant cell walls and as energy storage in the form of starch and glycogen, respectively.
To create complex carbohydrates like disaccharides (like sucrose) and polysaccharides (like starch and cellulose), the monosaccharides combine through glycosidic linkages.
Thus, the correct option is B.

What is inherited trait ?Inheritance is defined as the transfer of genetic information from parents to their offspring.
The transferred characters or traits include eye color, hair color, and blood type.
Trait can be defined as the genetic character which can be transmitted by the parent to its offspring during fertilization.
The trait which is expressed phenotypically is called as dominant trait while the other trait which is not expressed called as recessive trait.
These variations are observed in the species due to survival benefits or genetic drift.
Acquired traits are acquired by an individual in his lifetime which is due to their own activities or external influence.
Like inherited traits, acquired traits are unable tp pass to the next generation like ability to dance, cook.
