phenotypes are expected in the offspring of this cross?
From a cross of homozygous dominant and homozygous recessive parent lines with heterozygous parents, a 1:1 phenotypic ratio is seen. Two types of phenotypes will form.
A dihybrid cross involves two traits. Example: an animal with both genes for height and body coloration is taken . The height is represented as T. T is for tall characters, and t is for short characters. A homozygous dominant character is represented as TT. Homozygous recessiveness is expressed by tt.
Another gene such as body coloration is taken. Black (B) is dominant over white (b). An animal with homozygous dominant is BB. An animal having homozygous recessive is bb.
A parent with homozygous dominant for tall character and homozygous recessive for body colour is represented by TTbb. An animal that is heterozygous for height and body coloration is taken as TtBb.
From the crossing, two phenotypes are derived, such as tall black and tall white. Out of all eight individuals, four are tall black and four are tall white. The phenotypic ratio is 1:1. The cross is explained below.
Hence, two types of phenotypes will be formed with a phenotypic ratio of 1:1.

the cross is AAbb*AaBb
There would be 4 different genotypes and 2 different PHENOTYPES for the offspring. (From the first gene we can get AA or Aa from the second one Bb or bb)
AAbb
Aabb have the same phenotype
AABb
AaBb have the same phenotype
Answer:
they are all non-green plants
Newton's third law of motion states that for every action in nature there is an equal and opposite reaction. This law is also known as action-reaction law.
Newton's third law of motion states that for each and every action (force) in nature there is an equal and opposite reaction. This says that forces always act in pairs they do not act independently. Action and reaction forces are the forces of equal and opposite magnitude, but they are not balanced forces because they act on different objects hence they don't cancel out each other.
For example, if an object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, the forces result from interaction between the two.

For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
The correct answer is option B- sea anemone
Sea anemone belongs to group of marine animals, predator in nature. They belong to the phylum Cnidaria
Sea anemone has a foot like structure at the bottom which helps in attachment with rocks or anchor in sand but most of the species come near to the surface and float at the surface of water.
The most important and interesting factor about anemone is the presence of small tentacles around the mouth used to capture the prey.
Hey friends
The answer would be A
~Katie
To study objects too large
To study objects too small.
To study objects easily found in a lab.
To study events that take place over long periods of time.
Answer:
To study objects that are way too small
parasite
response
stimulus
Answer: stimulus
The stimulus would have the “animal” respond to change to survive
