Following the product probability rule and assuming independence among genes, the probability of an ABd gamete from an AABbDd individual is 1/4.
What does the product probability rule state?The product probability rule allows us to calcuate the probability of occurrence of two or more events at the same time. It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.
This rule is based on the dependence or independence of the events. Two events, A and B, are independent of each other if one of them does not affect the occurrence of the other one.
The rule establishes that the occurrence probability of two independent events -A and B- together is the multiplication product of the probability of occurring A by the probability of occurring B.
P(A∩B) = P(A) x P(B)
Available data:
A, B, C alleles are dominant over a, b, and c allelesThese genes assort independentlyIndividual AABbDdEach gamete will receive one of the alleles of each gene.
AA ⇒ Gametes can receive only A allele 2/2 A
Bb ⇒ Gametes can receive either B or b alleles ⇒ 1/2 B and 1/2 b
Dd ⇒ Gametes can receive either D or d alleles ⇒ 1/2 D and 1/2 d
The occurrence probability of ABd is
P(ABd) = P(A) x P(B) x P(d) = 2/2 x1/2 x 1/2 = 2/8 = 1/4.
The probability of an ABd gamete from an AABbDd individual is 1/4.

What are the advantages and disadvantages of slash-and-burn agriculture
Why do some flowers have so many pollen grains and ovules?
Answer:
The underlying as- sumption is that larger pollen grains contain more nutrients than smaller ones, at least those that store starch, and this allows their pollen tubes to grow through deep stigmas that can not be traversed by pollen tubes from small pollen grains. Pollen number and duration of stigma receptivity.

Other than carbon dioxide name two carbon compounds found in plants.
Answer:
See below.
Explanation:
Other than Carbon Dioxide (CO₂), two carbon compounds found in plants are :-
Glucose (C₆H₁₂O₆)Pyruvic Acid (C₃H₄O₃)The Calvin cycle, C3 pathway, or 3-phosphoglycerate photosynthesis are all names for the method by which plants fix carbon. PGA is a 3-carbon molecule.
What is the function of carbon in plants?The reasoning is simple Plants require atmospheric carbon dioxide to make food, and as a result of increased CO2 emissions from industry and autos, some crops and trees will grow bigger and faster.
Carbon is continuously exchanged between plants and the atmosphere. During photosynthesis, plants take up carbon dioxide, much of which is then stored in their roots in grasslands, and forests.
Therefore, Glucose and phosphoglycerate are the two carbon compounds found in plants.

List five cell organelles and describe their function.
Answer:
Ribosomes are tiny organelles that contain RNA and specific proteins within the cytoplasm. Within the cell, ribosomes are directly involved in the manufacture of proteins by using their RNA and amino acids.
This process involves decoding the information contained in the mRNA and using amino acids to produce the required proteins.
Mitochondria are some of the largest organelles within a cell.
Compared to some of the other organelles, mitochondria contain DNA which makes them semiautonomous. Mitochondria also contain a double-membrane with the inner membrane folding to form cristae.
Also known as the powerhouse, mitochondria play an important role in respiration where they generate ATP (adenosine triphosphate) from substrates in the presence of oxygen. Using their DNA, mitochondria are able to encode for some of the components they require to perform their functions.
The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell.
As such, it is actively involved in such both passive and active transportation to and from the cell. These processes also help maintain balance even when conditions outside the cell change.
The plasma membrane is made up of two layers of phospholipids (phospholipids bilayer).
Found in eukaryotic cells, Endoplasmic reticulum (ER) is the organelle that forms an interconnected network of flattened sacs (cisternae). Like some of the other organelles found in eukaryotes, ER is enclosed in a membrane. The ER is divided into two regions that vary in structure and function.
These include:
Smooth endoplasmic reticulum - The smooth ER is named so because it lacks a ribosome on its surface. As a result, it is more smooth in appearance as compared to the rough ER. It is involved in the synthesis of lipids (e.g. phospholipids) and carbohydrates that are used to build the cell membrane.

The process of crossing over occurs in what phase of meiosis.
Answer:
A crossover happens in the first stage, or division in meiosis.
Explanation:
The crossing over is when the two chromosomes exchange segments with each other. To make sense of it, the parent's two DNA is mixing up to create the baby, so it makes sense to have that the first step, because you would not exist with your parent's DNA.

Wetlands help slow the process of erosion by trapping sediments. Please select the best answer from the choices provided T F.
Wetlands help slow the process of erosion by trapping sediments. This statement is true.
What do you mean by Wetlands?Wetlands are the areas where the soil contains an excess amount of water in it.
Wetlands generally function as normal sponges and gradually release the water outside in the soil. And due to this excess amount of water, soil gains its properties by trapping sediments that lead to the slow down of the erosion process.
Therefore, Wetlands help slow the process of erosion by trapping sediments.

The food web shows how organisms are interconnected in a feeding relationship and how changes in one organism's population affect other organisms.
What is feeding relationship?A feeding relationship shows how two or more organisms which interact together to obtain food are affected by changes that occur to either of the organisms in the relationship.
An example of a feeding relationship is one between the phytoplankton, the shrimp, the crab, the octopus, and the sea otter.
Phytoplankton are producersShrimp eat phytoplankton Crabs eat shrimps Octopus eat crabsSea otters eat octopusIf the crab population increased, the octopus population will increase due to availability of more food.
The sea otter population will increase if the crab population increased due to increase of individuals in the food chain.
The carrying capacity will decrease if all of the producers in the food web died because their will be no food to support the organisms in the food web.
The total energy availability in the ecosystem will increase if sea urchin shrimp, and baleen whales increase because increase in organisms.
The carrying capacity of octopus in the ecosystem will increase if more shrimp move into the ecosystem.

a chemist takes a polysaccharide and turns it into many disaccharide. what reaction has the chemist performed and what must he add
Answer:
hydrolysis
Explanation:
Water must be added to break the bonds in a polysaccharide, in order to become disaccharides and eventually monosaccharides.
Polysaccharides are composed of long polymerics of the monomeric sugars joined by linkages. A polysaccharide can be converted into a disaccharide by adding water through hydrolysis.
What is hydrolysis?The hydrolysis reaction is the chemical reaction that involves the breaking of chemical bonds by adding water molecules. The water acts as a nucleophile that eliminates, substitutes, and performs another process to break the bonds.
The polysaccharides are made by linking the monomers of the sugar that can be converted into disaccharides by adding water to the reaction so that it breaks the linkages between the sugar molecules to produce two sugar molecule structures. The large molecules produce smaller molecules.
Therefore, polysaccharides can be converted into disaccharides by adding water.
