In the following pedigree showing the transmission of Cystic Fibrosis, an
autosomal recessive condition, what must the genotype of the indicated woman
be?
A: FF
B: Ff
C: ff
D: cannot determine
*red circle is affected female*
*blue circle is normal female*
*red square is affected male*
*blue square is normal male*
In the pedigree showing the transmission of Cystic Fibrosis, the genotype of the marked woman will be FF or Ff. Thus, options A and B are correct.
What is a pedigree?Pedigree represents the heritable phenotypic trait in the form of charts and diagrams. Cystic Fibrosis disease is inherited by the autosomal recessive alleles and is possible only if the genotype is ff.
The genotype for the woman being normal should not have recessive alleles and only can be heterozygous or purebred dominant. It is possible only if the genotype is Ff and ff.
Therefore, the genotype of the indicated woman will be Ff and ff.

A placebo is a fake treatment that mimics the experience of the experimental group.
true
false
Answer:
true
Explanation:
Doctors (or scientists) usually use this to make sure people aren't lying about the experience.
For example, some people might expect that if they take ibuprofen or Tylenol, they won't feel as much pain, so they might make themselves believe that they aren't feeling said pain. If you use a placebo group, you are less likely to have situations like that occur, and so your data becomes more accurate.
I need help with modeling a carbon cycle, do you mind helping me? :)
Will mark brainliest :D
Explanation:
The Carbon Cycle
The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.
Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.
Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.
Carbon moves through our planet over longer time scales as well. For example, over millions of years weathering of rocks on land can add carbon to surface water which eventually runs off to the ocean. Over long time scales, carbon is removed from seawater when the shells and bones of marine animals and plankton collect on the sea floor. These shells and bones are made of limestone, which contains carbon. When they are deposited on the sea floor, carbon is stored from the rest of the carbon cycle for some amount of time. The amount of limestone deposited in the ocean depends somewhat on the amount of warm, tropical, shallow oceans on the planet because this is where prolific limestone-producing organisms such as corals live. The carbon can be released back to the atmosphere if the limestone melts or is metamorphosed in a subduction zone.

the ending for the top is (if false correct the. then so on) (complementary dna strand for the next) will mark brainlest! i couldn't fit all the words on here since its a paper
Answer:
1. True
- Those are compounds
2. False
-They are actually polar molecules
3. True
-Acids are molecules that give away a type of subatomic particle
4. False
-While they are usually the same, it is not necessary to have equal protons and neutrons. However, the ratio of electrons to protons is always equal. An extra proton in an atom makes a new element and an extra neutron creates an isotope.
5. False
-An isotope is an atom that has gained an extra neutron.
6. True
-Oxygen is more electronegative than most of the halogen elements.
7. True
-Cellulose and starch are both polymers made from a glucose monomer.
8. True
-During DNA replication both strands that make up the double helix are used as a template that new strands copy.
9. True?
- I think the question is referring to a codon/nucleotide triplet, because each base cant specify a single amino acid and nucleotide triplets are made up of three nucleotide bases so id say true.
10. True
-Side chain groups vary in size, shape, charge, hydrophobicity, and reactivity, which makes them unique.

The image shows a vulture soaring over a rocky cliff. The arrows model the different ways energy moves between the sun, atmosphere, and geosphere.
Match each type of energy transfer to the arrows shown in the image. Describe how energy transfer helps the vulture soar above this rocky cliff.
Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.
The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.
Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.
The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.

What is the relationship between ribosomes and rough endoplasmic reticulum (ER)?
Rough ER produces the polypeptide chains that ribosomes need to make protein.
Rough ER is the subunit of ribosomes that makes proteins
Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell
Ribosomes transport proteins made by rough ER to the Golgi apparatus.
Answer:
Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell
Explanation:
Trust me i got you
Ribosomes attached to rough ER make protein that the rough ER then transports around the cell.
What is rough Endoplasmic reticulum?Rough endoplasmic reticulum (RER), series of associated leveled sacs, part of a nonstop film organelle inside the cytoplasm of eukaryotic cells, that assumes a focal part in the blend of proteins. The unpleasant endoplasmic reticulum (RER) is so named for the presence of its external surface, which is studded with protein-orchestrating particles known as ribosomes.
This element separates it hastily and practically from the other significant sort of endoplasmic reticulum (emergency room), the smooth endoplasmic reticulum (SER), which needs ribosomes and is associated with the union and stockpiling of lipids. RER happens in both creature and plant cells.
