Problem 3: Unfortunately Punnett Squares are not always for finding out the best parts about parenting. They are often, as you will see in the next few lessons, often used to determine the probability of a disease being passed on to a child. We'll have you try one and see what that looks like. One such disease is Cystic Fibrosis. Let's assume both parents are heterozygous for Cystic Fibrosis. That means both parents carry the recessive gene for the disease, but because of the dominant genes they have, they don't have it. However, they want to know if they try to have a child, what the chances of the child would be for having Cystic Fibrosis?
Answer:
eh
Explanation:
A small and this of spring will be impacted, and this offspring will be normal. Therefore, it is clear that there is a 25% risk that the progeny may be impacted. Due to the fact that one in four people have cystic fibrosis, we can thus state that the likelihood that either of these two people's offspring will be affected is four to one. Therefore, this will be our last arm.
What is cystic fibrosis?The lungs, digestive system, and other body organs suffer severe damage as a result of the genetic condition cystic fibrosis (CF).
Mucus, perspiration, and digestive juice production are all impacted by cystic fibrosis. Normally thin and slick, they released fluids. However, CF patients' secretions are thick and sticky due to a gene abnormality. The secretions clog up tubes, ducts, and passages rather than functioning as lubricants, notably in the pancreas and lungs.
People with cystic fibrosis can normally go to school and work, but the disease is progressive and necessitates daily care. In many cases, their quality of life is higher than it was for those with CF in the past. CF patients may now live longer because to advancements in diagnosis and therapy.

Which of the possible examples below would most likely lead to a change in the cell theory? A Scientists find life on Mars that is not made of cells. BScientists identify a cell organelle that practices the process of photosynthesis. C Scientists determine that an organism is living if it is made of twenty structurally-identical cells. D Scientists gather life from a volcano that is composed of cells which are very different from humans.
Answer: Probably B?
Explanation:
The possible examples below would most likely lead to a change in the cell theory: Scientists discover life on Mars that is not made of cells, i.e., option A, despite the fact that the cell theory states that all living organisms are made of cells.
What is the significance of the cell and its importance?Cell theory explains that life is made up of cells, but If scientists were to discover life on Mars that did not fit this definition, it would challenge the current understanding of the cell theory and the discovery of life on Mars that is not composed of cells would indicate that the cell theory is not universally applicable.
Hence, the possible examples below would most likely lead to a change in the cell theory: Scientists discover life on Mars that is not made of cells, i.e., option A, despite the fact that the cell theory states that all living organisms are made of cells.

What is the Sun’s role in Photosynthesis and what type of energy conversion occurs
during the process?
Answer:
Explanation:
Sunlight is needed for photosynthesis because the solar energy is what is converted to chemical energy by the plant's chloroplasts. This energy is necessary for the production of glucose, which provides usable energy for the plant. the energy convertion turns solar energy into chemical energy
Plants use sunlight to convert nutrients into energy. What form of energy transfer is taking place?
The*blank1*energy of the Sun is converted into*blank2*energy by the plants.
options for blank1= chemical, potential, radiant, sound
options for blank2=chemical, kinetic, mechanical, thermal
Answer:
Osmosis is the form of energy.

Q. what will happen to a plant if its xylem is removed ?
Q. In which chamber of heart is oxygenated and deoxygenated blood found ?
Pls mate ans fast, hurry up
➜ The xylem tissue transports water and minerals from the soil to the leaves of a plant for photosynthesis. If xylem is removed, upward movement of water will stop leading to wilting of leaves and ultimately causes death of that plant.
➜ Oxygenated blood ⇢ It is found in left auricle and left ventricle.
Deoxygenated blood ⇢ It is found in right auricle and right ventricle.
The energy that enters or leaves a living system during cellular processes comes from:
A transforming matter into energy
B the kinetic energy of electrons in motion
С
the building or breaking of chemical bonds
D absorbing heat in the environment

Why are ribosomes necessary for both Prokaryotic and eukaryotic cells to function properly?
Answer:
ribosomes are found in both cells
Explanation:
Ribosomes are special because they are found in both prokaryotes and eukaryotes. While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins. ... The attached ribosomes make proteins that will be used inside the cell and proteins made for export out of the cell
