Mass is measured by balance and weight is measured by balance.
Is mass measured by Pan balance?Two pans are located on either side of a lever in the pan balancing scale. To achieve balance and determine the weight of the other thing, weights are placed on one side of the object and on the other side. Typically, the mass is expressed in grammes or kilogrammes.
Because of its practicality and accuracy, comparative weighing is frequently used to compare two things' masses rather than their absolute values. When preparing reagents and stock solutions, a top pan balance is typically used for rough weighing because minor weight differences do not significantly affect the outcome of analysis.
Two pans are integrated into this particular laboratory scale on either side of a lever. It has two separate applications.

All of an organism's characteristics are inheritable which evolves over millions of years. An example of this is the modern day horse's foot.
What is Evolution?This is referred to as the change in the heritable characteristics of biological populations over successive generations.
All an organism's characteristics can be inherited and evolves over a period of time as a result of the changing environmental conditions which helps them to adjust thereby increasing their chances of survival hence preventing extinction of species.
For example, over millions of years of evolution, many horses lost their side toes and developed a single hoof as a result of them needing to move at faster speeds to evade predators.

Number of matings of roan-coated cows and roan coated bulls resulted in the following
When red cattle breed with red cattle, the resultant offspring show both red and white fur, resulting in a mixed coat pattern called "roan."
What is a roan bull?The roan pattern, normally in Shorthorn cattle, is inherited as a heterozygous genotype. Roaming is usually the intermixing of two dissimilar colored hairs - black and white make a blue roan while red and white make a red roan.
The roan coat color in livestock species is distinguished by a mixture of white and tint hair in cattle, If it is a breed that has the roan color pattern, like a Shorthorn, then yes it can be pure-blooded. Or it can be a cross-breed with the roan color pattern. Roan is a color, not a breed.

Explanation:
What are air masses, and how do they work? Don't copy and paste.
What are Air Masses: They large volumes of air that have generally the same temperature and pressure.
How they work: One is heated by an electrical current, the other is not. As air flows across the heated wire, it cools down.
Example of an Air Mass: The air masses in and around North America include the continental arctic, maritime polar, maritime tropical, continental tropical, and continental polar air masses. Air is not the same everywhere.
Fact: Unstable air masses have different temperatures and pressures.
How they are formed: An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.
*** The Earth's major air masses originate in polar or subtropical latitudes.
What percentage of the population can determine their blood type from
saliva, tears,sweat, or milk? (Numerical answers only) thanks
About 80% of the population can determine their blood type from saliva, tears, sweat or milk. These are known as secretors, and they refer to the fact that antigens present in the blood can also be found in bodily fluids like saliva.
What are antigens?Your immune system uses antigens as markers to determine whether or not something in your body is hazardous. Viruses, bacteria, cancers, and healthy bodily cells all include antigens. Antigen testing is carried out to identify viral infections, keep an eye on specific illnesses, screen for them, and ascertain a donor's compatibility with a transplant.
What are secretors?The term "secretor status" describes whether water-soluble ABO blood group antigens are present or absent in a person's body fluids, including saliva, tears, breast milk, urine, and semen. People are classified as secretors or non-secretors depending on whether they secrete certain antigens in their body fluids.

A woman and man have approached you for genetic counseling and are concerned about a hereditary form of deafness in their family. Both have normal hearing and there are no children. The woman's father has autosomal dominant sensory-neural deafness. Assume he is heterozygous. This hearing impairment displays onset at about age 10, and penetrance appears to be about 70%. There is no family history of deafness among the man's relatives. What is the probability that the woman is a carrier of the deafness allele
Answer:
35% is the probability that the woman is a carrier of the deafness allele
Explanation:
Both man and woman have normal hearing
Woman's father has autosomal dominant sensory-neural deafness - Dd
Genotype of heterozygous Woman's father = Dd
Let us assume that woman’s mother has normal hearing = dd
Dd * dd
Dd, Dd, dd, dd
Two deaf and two normal offspring.
Since the penetration is of 70%, the probability of woman being a carrier is
½ * 70% = 0.35
If a scientist wanted to follow Mendel’s experiment with a different kind of plant, which type of plant would she examine?
Answer: Pure line plant
Explanation:
Pure line plants are those plants that are used for breeding and selecting organisms with a desire trait to a number of generations until the wanted trait is established. Mendel had chosen pea plant for his experiments and that was a pure line species. It was bred to many generations so as to obtain the desired trait in successive generation. The plants were utilized to study the laws of inheritance. Also it was noticed that one trait being recessive in one generation will be expressive in other generation.

Compare the punnet squares you constructed in Activity 4, "Breeding Corn", with the punnet squares you constructed in this activity. By answering the following questions, show how the possible outcomes of a cross for one trait help analyze two traits.
A. How did you need to change the punnet square to consider two traits?
B. How would you need to change the punnet square if you were to consider three traits?
Punnett squares represent the possible genotypes of the offspring according to the parental's gamete combinations. The number of gametes depend on the number of alleles and traits considered. A) New rows and columns were added to the square because each parent contributed with four types of gametes (4 rows and 4 columns). B) The square would be constructed with eight rows and eight columns.
What is a Punnett square?
The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.
Punnett squares are composed of columns and rows in which all the different potential gametes are placed.
columns represent one of the parental gametes, and rows represent the other parental's gametes.The intersection between each column and row suggests a possible genotype among the offspring.
The number of columns and rows will depend on the number of genes involved in the cross. We can use the formula 2ⁿ to figure out how many gametes are possible (2 is the number of alleles, and n is the number of genes). Assuming diallelic genes,
If we consider only one gene, two types of gametes are possible (2¹). If we consider two genes, four types of gametes are possible (2²). If we consider three genes, eight types of gametes are possible (2³)
Punnett squares shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
In the exposed example, we need to compare a punnett square in which we consider only one gene with a punnett square in wich two genes are considered.
From activity 4: Punnett square

In these crosses, we only consider one diallelic gene that expresses complete dominance.
Punnett squares are composed of two columns and two rows in which both types of gametes are located.
Now, we need to consider two genes (P and S), which means four alleles are involved and four type of gametes are possible.

A. How did you need to change the punnet square to consider two traits?
Since we consider two traits, we need to add rows and columns according to the possible gametes. The new punnett square must have four columns and four rows (2ⁿ = 2² = 4).
Remember that all the possible gametes depend on the number of possible allelic combinations.
B. How would you need to change the punnet square if you were to consider three traits?
If we consider three traits, we need to construct a Punnett square with eight columns and eight rows (2ⁿ = 2³ = 8).

When blood passes through a capillary bed in the
it downloards O2 and uploads CO2.
Answer:
Exchange of gases takes place at alveoli sacs of lungs, which are equipped with capillary vessels or bed.
Explanation:
On inspiration or taking air through nostrils, surrounding air enters the lungs and it reaches air sacs or alveoli. Here, the outside air will have more amount of oxygen when compared with oxygen in blood at that site. Hemoglobin in the blood have high bonding capability to oxygen, so it captures oxygen and takes it to heart for pumping into other parts of the body. Likewise, the circulations continues from lungs to heart > hear to body parts > body parts to heart > heart to lungs for purification.

Answer B; When putting a material in an acid, many things could happen. This things that happen are called chemical reactions. Not every material will have a chemical reaction so this step could be useless.
Answer C; Chipping a piece off of a material will not grant you much information. Yes if may be easier to experiment will a smaller piece but the action by it's self is not useful.
Answer D; Scratching a material will another material can be very helpful. If you have two materials, labeled A and B, you can find out the Mohs hardness scale. If A is damaged by B, the hardness of A is less than B and vise versa. This can be very helpful when identifying materials.

Does every gene combination show up in the offspring?
Answer:
Answer!
Explanation:
Okay so, genes come in different varieties; which are called allele. somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. BUT, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
During meiosis I, chromosomal pairs randomly align along the metaphase plate. Each chromosome pair member carries one allele for each gene. Every gene combination shows up in the offspring.
Chance determines which of the 23 homologous pairs of both parents' chromosomes are inherited. The possible combinations of 23 chromosomal pairs total 8,324,608. As a result, the chromosomal combinations of two gametes are almost never identical.
Actually, each parent has two distinct gene pools. Additionally, only half of each parent's DNA is passed on to their offspring. and that the randomness of the portion that is passed down. All of these factors work together to guarantee that every child has a distinct collection of genes.
