If a claim is mainly supported by anecdotal evidence (stories or claims by people), It is
likely
Answer:
Biased.
Explanation:
Anecdotal evidence is described as the evidence that is based entirely upon an individual's personal experiences or observations.
As per the question, a claim based on such evidence is most likely to be biased as anecdotal evidence is based on a limited selection of examples that either support or refute the claim but not supported by any scientific or statistical analysis. Due to this undue bias, anecdotal evidence is not considered reliable as it displays the personal opinion, feeling, or experience of an individual. Thus, it may be used to negate the general statements but not to support r substantiate a claim or argument.

Which of the following describes the difference between the motion of liquid water and water vapor?
A. The particles in the liquid do not move, but the particles in a gas can move back and forth.
B. The motion of the particles is the same in both states, but they move slower in the gas state.
С. The particles in a gas can slide past each other, while the particles in a liquid are locked in place.
D. The particles in a liquid can slide past each other, while the particles in a gas are free to move in all directions.
The particles in a liquid can slide past each other, while the particles in a gas are free to move in all directions. So the correct option is D.
What is the motion of liquid particles?
Particles in liquids are dispersed randomly across the container and are relatively near to one another. Due to the closer proximity of the particles, collisions between them happen more often than in gases even if particles are moving quickly in all directions. The particles travel more quickly as the temperature rises, gaining kinetic energy along the way, leading to higher collision and diffusion rates.
The particles in a solid are arranged neatly and orderly, packing together as closely as they can. The particles are locked together too tightly to allow for movement from one location to another, yet they do vibrate in relation to where they are located within the framework. The particles gather kinetic energy and vibrate more quickly and vigorously as the temperature rises.
Therefore the correct option is D.

Why do classification systems change over time?
Scientists find new evidence in their studies,
Scientists use old methods of classification.
Scientists repeat experiments and find no changes.
Scientists find similar evidence to previous work.
Answer:
Classification system changes because the scientists find new evidence in their studies.
Explanation: The world is always changing and growing and dying as well as developing, so over time things change. For example, as you grow up do you stay the same? No, you notice the physical changes happening, well thats sort of like how the earth and its ways are always changing as well.
Classification systems change over time - Scientists find new evidence in their studies
Millions of plants, animals, and microorganisms are present on the earth. They have been identified by scientists, however, There are many new species are still being discovered around the world.
Scientists find new evidence and species that may have to change classification systems in order to manage new systematics and taxa or ranks.to classify these newly discovered species, with new characters, new systems of classification have to be devised every now and then.Thus, Classification systems change over time - Scientists find new evidence in their studies

Stroke volume is the amount of blood that leaves the left ventricle of the heart with each contraction. If a person has a stroke volume of 80 ml/beat, how many liters would that be?
Explanation:
The amount of blood that leaves the left ventricle of the heart with each contraction is called Stroke volume.
A person has a stroke volume of 80 ml/beat. It means that it is 80 milliliters per beat.
We need to find how many liters would that be.
We know that, 1 litre = 1000 milliliters
1 mL = 0.001 L
To convert 80 mL to litres, we can do it as follows :
80 mL = (80 × 0.001) LL
= 0.08 L
Hence, he stroke volume of a person is 0.08 L/beat.
Termites are unable to digest some plant materials (fiber). Termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.

MUTUALISM
Explanation:
MUTUALISM is a symbiotic relationship that exist between organisms in which both the organism benefit from the relationship and there is not loss.
It is MUTUALISM because, the termite benefited from the relationship because the bacteria help it to digest and break cellulose for easy absorption and the bacteria benefited by obtaining accomodation and feeding on the left over of termites.
The two organisms actually benefited from each other.

Explanation:
If water molecules surround a solute particle with their oxygen ends all pointing to the solute particle, what can you conclude about the charge of the solute particle? Is it positive, negative, or neutral, and how do you know?
Answer:
It is +
Explanation:
Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen. So your solute would attract the opposite charge which is the Oxygen
Polar water molecules have partial positive hydrogen charges and partial negative oxygen charges. Thus, oxygen would attract your solute having positive charge.
What is polarity?Polarity is the separation of electric charge that occurs when a molecule or its chemical groups have an electric dipole moment. This results in the molecule or chemical group having one end that is positively charged and one end that is negatively charged. Because of the disparity in electronegativity between the atoms that are linked together, polar molecules are required to have one or more polar bonds.
Polar water molecules have partial charges in both the hydrogen (positive) and oxygen (negative) directions, though mostly in the hydrogen's favor.
Therefore, oxygen would be attracted to your solute if it had a positive charge.

In a cross of Limnaea, the snail contributing the eggs was dextral but of unknown genotype. Both the genotype and the phenotype of the other snail are unknown. All F1 offspring exhibited dextral coiling. Ten of the F1 snails were allowed to undergo self-fertilization. One-half produced only dextrally coiled offspring, whereas the other half produced only sinistrally coiled offspring. What were the genotypes of the original parents?
Answer:
the genotypes for the original parents must have been Dd x dd
Explanation:
Maternal inheritance refers to those cases in which certain phenotypic traits depends on the maternal genotype, independently of the individual genotype. In a cross, the genotype follows the Mendelian model, but the phenotype is influenced by the maternal genotype. The phenotypic traits of generations F1, F2, F3, and so on, do not correspond to the expression of their own genes, but ti the expression of the maternal genes.
Maternal inheritance has been studied in the Lymnaea species. In gasteropods, the dextral coil is clockwise, while the sinistral coil is counter-clockwise. Dextral is expressed by the dominant allele (D), while sinistral is expressed by the recessive allele (d).
In the exposed example:
The snail contributing the eggs (females) was dextral but of unknown genotype --> D-Both the genotype and the phenotype of the other snail are unknown.All F1 offspring exhibited dextral coilingIn the F2, One-half produced only dextrally coiled offspring, whereas the other half produced only sinistrally coiled offspring.Cross)
Parental) D- x --
F1) 100% dextral (The whole progeny exhibited the dextral trait because the
individual that contribute the eggs was dextrally coiled)
F2) 50% dextral
50% sinistral
The fact that the F2 expresses 50% sinistral and 50% dextral means that one of the progenitors that contributed with the eggs (female) must have had at least one of the dominant allele D for the dextral trait, while the other female must have had the recessive genotype dd for the sinistral trait.
So the genotypes for the original parents must have been Dd x dd
1st Cross:
Parental) Dd x dd
The snail contributing the eggs Dd
the snail contributing the sperm dd
F1) 2/4 = 1/2 Dd
2/4 = 1/2 dd
100% expressing dextral coiling
2nd Cross:
Parental) Dd x Dd dd x dd
F2) 1/4 DD 100% dd
2/4 Dd 100% Sinistral coiling
1/4 dd
100% Dextral coiling
50% of the F2 exhibited dextral coiling, while the other 50% exhibited
sinistral coiling

A. No precipitate is formed.
Explanation:
Hello,
In this case, considering that both calcium chloride and barium chloride are CaCl₂ and BaCl₂ respectively, due to their high polarity by cause of the ionic bond they have between calcium and chlorine and barium and chlorine we say they are highly soluble in water, therefore, A. No precipitate is formed.

The hormone oxytocin aids the birth process by stimulating:__________
Answer:
The hormone oxytocin aids the birth process by stimulating: uterine wall contractions.
Explanation:
Oxytocin is a hormone that is released naturally in the body of women and that intervenes in certain physiological processes, activating behaviors at a mechanical level in specific organs such as the uterus and the breasts. In the case of the uterus, oxytocin stimulates and maintains the contraction of the smooth muscle of the uterus during labor and delivery, that is, it is responsible for the existence of contractions, which occur during intercourse, due to the distension of the uterus that occurs produced during labor.
