Answer:
3) the dog received one gene for brown and one for black
The most likely reason for the brown fur in one of the offspring is that the dog received one gene for brown fur and one gene for black fur.
WHAT IS HETEROZYGOSITY?Heterozygosity is a genetic condition whereby a gene is made up of two different alleles.
According to this question, the breed for black fur (B) is dominant and the gene for brown fur (b) is recessive in the breed of dogs. If two dogs with black furs are crossed, one of the offspring has a brown fur.
The reason for the above observation is that the black-furred parents were both heterozygous i.e. Bb, hence, the dog received one gene for brown fur and one gene for black fur.

How do evolutionary developments of the trilobites represent stability over the long term, and change over the short term ?
Answer:
I am having trouble with the same question as well.
Explanation:
Can anyone help us.
The evolutionary modifications in trilobites could have occurred relatively quickly but there are periods with little to no change to the species.
Trilobites represent an extinct group of animals that disappeared during the end Permian mass extinction event.This event (Permian mass extinction) removed over 90% of all species on Earth. The equilibrium punctuated theory suggests that there are periods of very little change in the evolution of a species, and then periods having huge evolutionary modifications.In conclusion, the evolutionary modifications in trilobites could have occurred relatively quickly but there are periods with little to no change to the species.

Punnett squares??
I really don't understand this please help!!
Answer:
The genotypes would include 2 brown-eyed children, and 2 blue-eyed children.
Explanation:
Punnet Squares are really easy once you get the hang of it, it's a literal square that you match up the genotypes to create a probability of offspring.
x B b
b Bb bb Go to a certain square and multiple the top and bottom
b Bb bb variable together!
So there would be 50% brown-eyed children and 50% blue-eyes children!

what are functions do you think needed in coordination and balance
it an important question please answer it
Answer:
Posture and equilibrium.
Explanation:
Cerebellum is a part of brain that is responsible for the coordination and balance in the body. The other function of cerebellum is the regulation of motor movements in the body. It also functions to maintain posture and equilibrium in the human body that affects coordination and balance. Posture refers to the position in which a person holds its body in standing or sitting position.

How do Punnett squares help predict the outcomes of artificial selection?
Punnett squares can be used to combine the alleles from the mother and the father to ascertain the likelihood as well as potential genotypes and phenotypes that a child may acquire from their parents.
What are Punnett squares?
The Punnett square is a tabular summary of possible combinations of maternal elapse with paternal. The percentages of phenotypes in a cross's progeny from known genotypes can be predicted using a Punnett square.
Based on the other genotypes involved in the cross, a missing genotype can be identified using a Punnett square. A Punnet square displays the potential gene combinations in the child inside the square, together with the genes (represented by letters) in the parent gametes along the top and left sides of the square.
Therefore, Punnett squares can be completed to determine the likely outcome of a cross.

C. Carbon dioxide is a waste in cellular respiration in BOTH plants and animals
D. Carbon dioxide is a waste in cellular respiration in plants but NOT in animals
Answer:
C. Carbon dioxide is a waste in cellular respiration in BOTH plants and animals
Explanation:
Cellular respiration occurs in animals and plants. It breaks down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.

The Grand Canyon is made of sedimentary rock that contains fossils up to 1 billion years old. The
most commonly found fossils in the Grand Canyon are sea organisms (crinoids, brachiopods, and
sponges). However, several upper layers of rock contain terrestrial, or land-based, fossils, such as
dragonfly wing impressions and the footprints of scorpions, centipedes, and reptiles. What do
these fossils tell us about the evolution of the geosphere at the Grand Canyon?
ats
Answer:
It tell us that aquatic environment changed into land environment.
Explanation:
These fossils tell us about the evolution of the geosphere from aquatic environment to land environment at the Grand Canyon because the presence of sea organisms which is only found in the sea. Millions of years ago there was a sea at the Grand Canyon that have sea organisms crinoids, brachiopods, and sponges etc but with the passage of time all water removed from this area and this aquatic environment change into the land environment.

5 points
A. Water vapor rises and get hot.
B. Water vapor rises until it cools and condenses
C. It adds salt to the ocean and water.
D. Water vapor disappears.
Answer:
B. Water vapour rises until it cools and condenses
Explanation:
Water vapour spends regarding 10 days within the air. As water vapour rises higher within the atmosphere, it begins to chill backpedal. once it's cool enough, the water vapour condenses and returns to liquid water. These water droplets eventually gather to make clouds and precipitation.

Please tell me, in your own words, what you know about the ideas of natural selection
and evolution.
Explanation:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Those that are better physically equipped to survive, grow to maturity, and reproduce. ... Biologists have since observed numerous examples of natural selection influencing evolution.
