The only expression that is true is 8/7 × 9/10 = 72/70.
What is expression with example?
In mathematics, an expression is a combination of symbols, numbers, and operators (such as +, −, ×, ÷) that represents a mathematical quantity or relationship. Expressions can be simple or complex, and they can involve variables, constants, and functions.
For example, "2 + 3" is an expression that represents the sum of 2 and 3. Another example is "4x − 7", which represents the result of subtracting 7 from the product of 4 and a variable x. In this case, x is a variable, and its value can vary depending on the context in which the expression is used.
To explain, when multiplying fractions, you multiply the numerators together and the denominators together. In this case, 8/7 × 9/10 becomes (8 × 9)/(7 × 10) which simplifies to 72/70 by dividing both the numerator and denominator by their greatest common factor, which is 2 in this case. The other expressions are not true because the methods used to arrive at the numerators and denominators are incorrect. For example, in 7/10 × 9/8 = 16/18, the numerator should be 63, not 16, and the denominator should be 80, not 18. Similarly, in 10/7 × 9/8 = 90/15, the denominator should be 56, not 15.
Therefore, 8/7 × 9/10 = 72/70 expression that is true.

A genotype is a classification of the sort of variation found at a specific place (i.e., a locus) in the genome. Symbols can be used to symbolize it. For example, the letters BB, Bb, bb could be used to indicate a specific variation in a gene.
What is genotype?An organism's genotype is its entire collection of hereditary material. Genotype can also refer to the alleles or variations that a person possesses in a specific gene or genetic region. The number of alleles a person can have in a particular gene is determined by the number of duplicates of each chromosome present in that species, which is also known as ploidy.
Diploid animals, such as humans, have two complete pairs of chromosomes, implying that each person has two alleles for any particular gene. When both genes are identical, the genome is said to be homozygous. When the genes are distinct, the genotype is called heterozygous.

which of the following is most unreliable in establishing time of death?
A. Rigor mortis
B. putrefaction
C. postmortem lividity
D. muscular viscidity
Answer:
D
Explanation:
D. Muscular viscidity is the most unreliable in establishing the time of death.
Muscular viscidity, also known as rigor caloris, is the stiffening of muscles due to the coagulation of muscle proteins after death. Unlike rigor mortis, which sets in within a few hours after death and disappears after a day or two, muscular viscidity can persist for several days and is influenced by factors such as temperature and the type of muscle. Therefore, it is not considered a reliable indicator of the time of death.
On the other hand, rigor mortis, postmortem lividity, and putrefaction are all more reliable indicators of the time of death. Rigor mortis begins to set in a few hours after death and disappears within 24-36 hours. Postmortem lividity, which is the pooling of blood in the lowest parts of the body after death, becomes fixed after 8-12 hours and can help establish the position of the body at the time of death. Putrefaction, which is the breakdown of tissues by bacteria after death, follows a predictable pattern and can provide clues as to how long the person has been dead

Genotypes result from genes and allele combinations. Phenotypes are the expression of traits coded by these genes. A) Mouse genotype: Rr ll FF Tt Ee cc. Mouse phenoype: red eyes, small nose, brown fur, long tail, rounded ears, and no claws. B) 1- There are two letters because each of them represents an allele (the dominant and the recessive alleles). Both alleles are present in the mouse population, so they appear among the possible genotypes. 2- There are differences between your mouse and your partner mouse because the allele and gene combination is random
What are genotype and phenotype?Genotypes are determined by the way in which allele combinate during gamete formation concerning a gene coding for a trait.
When the alleles that compose the genotype are the same, we talk about Homozygousis. Homozygote individuals carry the same type of alleles, either dominant alleles or recessive allelesWhen the alleles that compose the genotype are different, we talk about Heterozygousis. Heterozygous individuals carry a dominant and a recessive allele.Usually, dominant alleles are represented with a capital letter, while recessive alleles are represented with a small one.
The phenotype is the expression of a feature coded by the genotype. It is the expression of a gene that codes for a trait.
The organism shows observable physical, biochemical, or behavioral characteristics.
To answer this question, I will propose some random genotypes.
I will assume complete dominance for each gene,
R codes for red eyesr codes for yellow eyesL codes for large nosel codes for small noseB codes for brown furb codes for white furT codes for long tailt codes for short taiE codes for round earse codes for ponty earsC codes for clawsc codes for no clawsA) Genotype and Phenotype
Genotype Phenotype
Rr Red eyes
ll Small nose
FF Brown fur
Tt Long tail
Ee Round ears
cc No claws
Mouse genotype: Rr ll FF Tt Ee ccMouse phenoype: red eyes, small nose, brown fur, long tail, rounded ears, and no claws.Now, you should draw a mouse with these traits.
B) Analysis
1) There are two letters because each of them represents an allele. Genes that code for these traits are diallelic.
One of them is a capital letter because it represents the dominant allele. The other letter is low because it represents recessive alleles.
Both alleles are present in the mouse population, so they appear among the possible genotypes.
2) There are differences between your mouse and your partner mouse because the allele and gene combination is random (see independent genes and independent segregation). Several combination possibilities result in different genotypes and phenotypes.

What combination of factors, such as distance, intensity, and duration of exposure could lead applause to negatively impact your hearing ?.
Explanation:
Applause can negatively impact your hearing if you are exposed to it at high intensity and for a prolonged period of time, or if you are in close proximity to the sound source. The specific combination of factors that can lead to hearing damage from applause include:
Intensity: The volume or loudness of the applause is a key factor in determining its potential impact on your hearing. The higher the volume, the greater the risk of damage to your hearing.
Duration: The length of time that you are exposed to applause can also impact your hearing. The longer the duration of exposure, the greater the risk of damage.
Distance: The distance between you and the source of the applause can also affect the potential impact on your hearing. If you are in close proximity to the sound source, the risk of damage is higher than if you are further away.
Frequency: The frequency or pitch of the applause can also play a role in determining its potential impact on your hearing. High-pitched sounds are generally more damaging than lower-pitched sounds.
Therefore, to avoid potential hearing damage from applause, it is important to consider these factors and take steps to reduce your exposure. This may include moving away from the sound source, wearing earplugs or other hearing protection, or limiting your exposure time
