If short hair (L) is dominant to long hair (l), then what fraction of the offspring produced by a cross of Ll x ll will have long hair
Answer:
The answer is 50%.
Explanation:
If we cross the two genotypes given in the question as Ll and ll, we can see that 50% of the offspring will have Ll as the genotype and the other 50% will have ll as the genotype.
Since L is the dominant gene, all the Ll genotypes will have long hair as a result of the dominant gene.

Seeing is believing. Do you agree or disagree with the statement above? Be sure to explain your reasoning and use examples from this lesson to support your view. connect to: the ideas of atomic theory, the scientists who helped develop atomic theory, the tools and techniques that were used to study matter, the conclusions that were, drawn from the study of matter, Then, examine the statement.
Answer:
I disagree.
Explanation:
For many years the phrase "Seeing is believing" has been propagated as a way to question and verify the information that reaches us. "Seeing is believing" reflects an evidential thought, where something must be witnessed and touched to be credible. We cannot agree with that.
Agreeing with this phrase is a way of denying all the scientific and technological advances that humanity has gone through. This is because there are countless things that could be scientifically proven and that we cannot see, such as DNA, atoms, molecules, RNA, among others. Atoms, for example, were proven through scientific techniques and devices that were modernized and allowed us to reach a conclusion without being able to see the atoms, but knowing that they are real.
We must not be denialists, especially in scientific matters, because science is one of the main factors for the advancement of society, without scientific advancement there is no progress.
Therefore, we must motivate the phrase "Seeing is believing" to "Proving is believing", which is very rational and coherent.

The provides a rigid structure that gives the cell its shape. The helps to transport ions, nutrients, and waste. allow DNA to be transferred from one bacterium to another.
Answer:
See the answer below
Explanation:
Since bacteria are prokaryotes, they have no nucleus and membrane-bound organelles. The outside of a bacterial cell is protected by a structure called a capsule. The cell wall provides a rigid structure that gives the cell its shape. The cell membrane helps to transport ions, nutrients, and waste. The plasmids allow DNA to be transferred from one bacterium to another.
The bacteria are microscopic organisms that are generally classified as prokaryotes. The prokaryotes lack nucleus and other membrane-bound organelles, unlike the eukaryotes. The bacteria cells are enclosed in a protective structure known as the capsule. Immediately after the capsule is the cell wall whose components vary depending on whether the bacteria is Gram-positive or negative.
Towards the innermost part of the cell, after the cell wall is the cell membrane. It acts as a channel for the transport of materials in and out of the cell. Some bacteria cells have short, circular, extrachromosomal DNA known as plasmids which can be transferred from one cell to another.

The wild type of allele for a gene has more pairs than the mutated form of allele what type of mutation A. a base pare of deletion B. base pair substitution C. base pair seperation D. base pair insertion
Answer:
A. a base pare of deletion
Explanation:
A base pair deletion is a mutation where one nucleotide is removed during DNA replication. The base-pair deletions produce frameshift mutations, i.e., they cause genetic modifications that alter the Open Reading Frame (ORF) of the corresponding protein. Examples of human diseases caused by deletion mutations include, among others, cystic fibrosis and Williams syndrome.

Fat produce greater energy than the carbohydrates and protein.
due to the facts fats and proteins both have carbon bonds
Explanation:
Fat have highest number of carbon bonds in comparison of the amount of the carbon bonds present carbohydrate and protein and similarly protein have greater number of carbon bonds
Digestion of the fats provides the most energy per gram, due to the fact that more carbon bonds to break. Protein as well gives the higher energy per gram if compared to carbohydrates.
Thus, the correct answer is -
Fat produce greater energy than the carbohydrates and protein.
due to the facts fats and proteins both have carbon bonds
Answer:
Fat
Explanation: (answer for second part)
The amount of carbon bonds in fat is much greater than the amount in carbohydrates and proteins. Fats give you the most energy per gram, so there must be more carbon bonds to break, thereby releasing more energy.
Calculate the percentage loss of mass between the sucrose solutions 0.1 mol/dm3and 0.5 mol/dm3. Give your answer to three significant figures
Answer:
The percentage loss in mass between sucrose solutions 0.5 mol/dm³ and 0.1 mol/dm³ is 80.0% loss in mass
Explanation:
The molecular formula of sucrose is C₁₂H₂₂O₁₁
The molecular mass of sucrose is 342.3 g/mol
Therefore;
The mass of sucrose in 0.1 mol/dm³ solution = 0.1 × 342.3 = 34.23 g
The mass of sucrose in 0.5 mol/dm³ solution = 0.5 × 342.3 = 171.5 g
The percentage loss in mass of the sucrose is given as follows;
[tex]Percentage \ loss \ in \ mass = \dfrac{Original \ mass - New \ mass}{Original \ mass } \times 100[/tex]
Therefore;
[tex]Percentage \ loss \ in \ mass = \dfrac{171.5 - 34.23}{171.5} \times 100 = 80.04 \%[/tex]
Which gives, the percentage loss in mass between sucrose solutions 0.1 mol/dm³ and 0.5 mol/dm³ is 80.0% to three significant figures.
What is physical science
Answer:
Physical science can be described as all of the following:
A branch of science (a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe).
A branch of natural science – natural science is a major branch of science that tries to explain and predict nature's phenomena, based on empirical evidence. In natural science, hypotheses must be verified scientifically to be regarded as scientific theory. Validity, accuracy, and social mechanisms ensuring quality control, such as peer review and repeatability of findings, are amongst the criteria and methods used for this purpose. Natural science can be broken into two main branches: life science (for example biology) and physical science. Each of these branches, and all of their sub-branches, are referred to as natural sciences.

DNA stores the genetic code, chromosomes are thread-like structures, and sister chromatids are two halves of chromosomes and a strand of DNA. Thus, option A is correct.
What is chromosome?The genetic code is stored in every cell of your body in the form of deoxyribonucleic acid (DNA). It makes your body's instruction manual. The DNA molecule is packaged into thread-like structures called chromosomes in each cell's nucleus.
The term "homologous chromosome" refers to chromosomes that share the same genetic foundation but may also have variants caused by replication. The two halves of a given chromosome that are held together at the centromere are called sister chromatids.
After the cell has gone through the process of DNA replication in order to get ready for cell division, chromosomes are known as "replication chromosomes" emerge.
Therefore, DNA stores the genetic code, chromosomes are thread-like structures, and sister chromatids are two halves of chromosomes and a strand of DNA. Thus, option A is correct.
