Cystic Fibrosis is a genetic disease of the lungs caused by a recessive allele. A man with Cystic Fibrosis marries a woman who does not have Cystic Fibrosis, but her father had the disease. What is the probability of the couple having a child that has Cystic Fibrosis?
Answer:
If only one of you is found to be a carrier, the chance that you will have a child with CF is very low, although not completely eliminated. If you are both carriers, each pregnancy will have a 1 in 4, or 25 percent chance of being affected with cystic fibrosis.

Please help!!! I don't know how to tell if they self pollinate or not.
Answer:
The first flower can self pollinate because it is open, so the wind will pollinate it.
Explanation: Flower b will not self pollinate because it is not open, so it will not pollinate until a bird or moose or any other animal comes and eats it, then poops it out, so the seeds get planted.

What is the function of the surface protein on the influenza virus?
A To protect
B To attach to a host cell
C To manufacture enzymes using a host's immune system
D To remove a host cells's DNA
Surface proteins are the proteins that are embedded in the cell membrane structure of organisms and help in cell interaction with the outer surrounding or other cells.
Surface protein on the influenza virus is needed for attaching to the host cell.
The surface protein of viruses can be explained as:In viruses, the genetic material is stored in these protein structures called capsids which protects the viral genetic material from degrading enzymes and other cellular enzymatic activities.Surface proteins on the viruses are needed to penetrate and attach to the host system and cells for inducing immune response and diseases.The surface proteins of influenza virus HA and NA are necessary for penetrating host mucus layers.Therefore, option B to attach to the host cell the surface proteins are needed.

Answer:
Yes
Explanation:
in order for you to fully function and stay alive the cells need to be replaced. mitosis is the reason we can grow, heal wounds, replace damaged body parts and cells. It also helps with organisms that reproduce.

called CF is a condition that causes excess mucus production in the lungs and if untreated causes early death. CF is caused by a deletion of 3 letters in the gene sequence. How might this deletion cause excessive mucus production?
Answer:
The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.
Explanation:
Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.
Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.
When your cells use fat for energy, the fatty acids are broken up into molecules of acetyl CoA. Predict how many ATP can be made from one molecule of acetyl CoA if oxygen is present. Show your work.
Answer: Suppose that each fatty acid in a certain fat can make 9 molecules of acetyl CoA. Predict how many ATP can be made from the fatty acids in this fat. This would make 27 acetyl CoA, and therefore would make 27 ATP
Explanation:
Help me describe how these protists feed, move, and reproduce.
A plant-like protist
A fungus-like protist
Ciliophoran
Zooflagellate
Sarcodinian
Sporozoan
Explanation:
Protists are mostly one-celled organisms. Some make
their own food, but most take in or absorb food. Most
protists move with the help of flagella, pseudopods, or
cilia. Some protists, like the one-celled amoeba and paramecium, feed on other
organisms.
Fungus-like protists share many features with fungi. Like fungi, they are heterotrophs, meaning they must obtain food outside themselves. They also have cell walls and reproduce by forming spores.
Ciliates reproduce asexually by division: the micronucleus undergoes mitosis, while in most ciliates the macronucleus simply pinches apart into two. This process is shown in the drawing above. However, ciliates also reproduce sexually, through a process known as conjugation. Conjugation is often induced by lack of food. Two ciliates of opposite mating types come close together and form a cytoplasmic bridge between the two cells; the micromuclei divide by meiosis, the macronuclei disintegrate, and the conjugating cells exchange haploid micronuclei over the cytoplasmic connection. They then separate, reform new macronuclei from their micronuclei, and divide, but remember that the essence of sexual reproduction is forming a new organism from the combined genetic material of parents. After conjugation, each ciliate partner has acquired new genetic material, and divides to give rise to progeny with a new combination of genes. This is essential to the survival of ciliate lineages; most ciliates cannot reproduce indefinitely by asexual fission, and eventually die out if prohibited from conjugating.
One convenient way to categorize protozoans is by how they move. Some move rapidly, while others creep slowly. Still others are not capable of active movement at all, but instead rely on a host organism to supply their food.
Protozoans With Flagella
Zooflagellates (zoh oh FLAJ uh lits) move by means of one or more flagella. (Recall from Chapter 6 that flagella are long, thin, whip-like cellular projections.) Zooflagellates generally reproduce asexually by binary fission. Recall that asexual reproduction results in genetically identical offspring.
Sarcodines reproduce sexually by syngamy (fusion of two gametes) and asexually by division or budding. In multinucleate forms, cytoplasmic division with distribution of the nuclei occurs.Members of the phylum Sarcodina are ameboid. They move about by using pseudopods and usually eat by phagocytosing food particles, usually bacteria. Some amoeba form calcium carbonate or silica skeletons called tests to protect themselves.
The sporozoans are able to form spore-like cells, from which they get their name. Sporozoans do not have flagella, cilia, or pseudopodia. They are capable of gliding movements. ... The apical complex secretes enzymes which allow the sporozoan to enter a host cell.Apicomplexan, also called sporozoan, any protozoan of the (typically) spore-producing phylum Apicomplexa, which is called by some authorities Sporozoa. ... Apicomplexans feed by absorbing either dissolved food ingested by the host (saprozoic nutrition) or the host's cytoplasm and body fluids.Protozoa reproduce asexually by fission, schizogony, or budding. Some protozoa can also reproduce sexually. Relatively few protozoa cause disease

How did you determine the types of cell division for both phases depicted in your model? Explain your answer.
Answer:
Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.
Explanation:
When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.
The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.
