Answer: There is a probability (n.b. NOT certainty) that half of all offspring will be colour blind.
Explanation: The female is XX and as an unaffected carrier we can assign genotype Cc where c is the recessive allele.
The male is XY and colour blind, so genotype cY
Male offspring can be cY or CY so p|colourblind = 50%
Female offspring can be Cc or cc so, again p= 50%
If there is also equal probability of sex of the offspring, there is an overall probability that half the offspring will be colour blind

together with Fr. Diego Luis de San Vitores, SJ , where did they go to evangelize? What heroic act merited him a martyr's crown?.
Answer: The spread of Christianity among the Jews was the heroic act of San Vitores.
Explanation:
He was murdered on the island of Guam on 2 April 1672. He brought Christianity to the CHamoru people. He was killed by the chief's daughter Mata' pang with a sword. His conversion efforts were commendable. The CHamorus people welcomed San Vitores and hundreds of people were readily converted into Christians readily. Today Catholism is the main religion in Guam.

Describe the process of water moving in and out of the cell.
Answer:
Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

How did the invention of the microscope contribute to knowledge about 1p living things?
Answer:
It made it possible for people to discover and learn about cells.
Explanation:
The cell is the basic unit of structure and function of all living beings. A cell can also be defined as a morphological, functional, and reproductive unit of all living beings.
Every living organism is made up of one or more cells. All cells are created from an existing cell. A cell is the smallest unit that has all the characteristics of life. A set of cells of similar or the same appearance, embryonic origin, and function is called tissue.
The science that studies the cell is called cytology. There are organic and inorganic compounds in the cell. Of the inorganic compounds, water and salts are the most common. Organic compounds in the cell contain carbohydrates, fats, and proteins.

How does the structure of DNA explain chargaff's rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.
What is Chargaff's rule?Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.
Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.

4.The aquarium (wet soil with dead organisms) that the earthworms live in
Answer:
1 community
2population
3ecosystem
4habitat
Explanation:
the classroom is a community because its people of different cultures and race that come together and be one
all the mice in the classroom are considered a population because population is the number of people in a certain area
in the third statement there are all forms of organisms hence showing the biodiversity that ecosystems tend to have
the aquarium provides shelter to earthworms proving them with food of which a habitat provides both shelter and food
Convection occurs because heated material becomes ____________________. A less dense and rises B denser and rises C denser and sinks D less dense and sinks
Answer: A less dense and rises
Explanation:
Convection is a type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases due to presence of less number of mmolecules per unit volume. As the hot liquid becomes less dense, it starts moving upwards.
Thus convection occurs because heated material becomes less dense and rises.

What is one way during the G0 phase that a mistake during the cell cycle could result in problens for the G0 phase?
The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.
Which muscle cells are often considered as G0 phase cells?Poly-nucleated muscle cells that do not undergo cytokinesis are often considered G0 phase cells.The G0 phase is seen as a distinct and quiet stage that occurs outside the cell cycle.
Mitosis is the procedure with the aid of which a mobile replicates its chromosomes after which segregates them, producing two identical nuclei in training for mobile division. Mitosis is generally followed by way of same department of the mobile's content material into daughter cells that have identical genomes.
The two phases of cell cycle are interphase in which DNA replication occurs, 3 stages of interphase are: G1 phase, S phase and G2 phase and mitotic in which division occurs phase. Mitosis occurs after the completion of DNA replication and doubling of chromosome number and cell contents and after mitosis, two daughter cells are produced of equal number of chromosomes.
Therefore, The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.

Why must an mRNA copy be made for Protein Synthesis?
A. Ribosomes cannot read DNA, only RNA.
B. DNA must stay inside the nucleus.
C. Ribosomes are too big to enter the nucleus.
D. DNA is too degenerate to use without mRNA.
Answer:
A
Explanation:
its not D or C and B might be true but its A okay
Why must an mRNA copy be made for Protein Synthesis because C. Ribosomes are too big to enter the nucleus
Why is mRNA important for protein synthesis?
mRNA is the molecule that includes the message contained within DNA to the ribosome. Ribosomes are where proteins are produced. mRNA is vital because ribosomes cannot attain the DNA inside our cell nucleus, which is the region within the mobile wherein DNA is housed.
Why is it important to make an mRNA reproduction of a DNA gene earlier than protein synthesis?
So as for cellular to fabricate these proteins, particular genes inside its DNA should first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into completely useful proteins.
