Answer:
BB = 81%, bb = 1%, Bb = 18%
Explanation:
p + q = 1
p^2 + 2pq + q^2 = 1
p is dominant and q is recessive so p = B and q = b
0.9^2 + 2(0.9 * 0.1) + 0.1^2 = 1
BB = p^2 = 0.9^2 =0.81
bb = q^2 = 0.1^2 = 0.01
Bb = 2pq = 2*0.9*0.1 = 0.18

Answer:
D
Explanation:
Which pattem of wind flow is most likely to occur during a hot summer season in a coastal location?
А
From land to sea, toward areas of lower air pressure.
B.
From sea to land, toward areas of lower air pressure
С
From land to sea, toward areas of higher air pressure.
D
From sea to land, toward areas of higher air pressure
Answer:
B. From sea to land, toward areas of lower air pressure
Explanation:
The pattern of wind flow is most likely to occur from sea to land during a hot summer season in a coastal location due to difference of air pressure. In the summer season when the land is heated, the temperature of the air also increases and hot air rises up, as a result a region of low pressure is created at the surface. The air over the sea moves into this area of low pressure on the land. Hence, the direction of the wind is from the sea to the land during the day in summer season.
What was the discovery scientists made in the 1950's that led them to then accept Wegener's theory of Continental Drift?
Answer & explanation:
The theory of continental drift emerged a long time ago. When mapping some points on Earth, scholars suspected that the continents were united in the past.
Francis Bacon suggested in 1620 that the east coast of the South American continent and the west coast of Africa fit together perfectly, giving the impression that they had parted in the remote past. A similar observation to this had already been made by another scholar named Abraham Ortelius, around 1596.
A century later, hypotheses became a scientific theory with previously elaborated arguments. Then, the theory of Continental Drift was officially born, when the German Alfred Wegener formulated it in 1912, establishing that the Earth had been divided, in its slow fragmentation, into two great continents, Laurasia and Gondwana.

Write a food chain from this food web with six trophic levels.
Answer:
Tiny water plants- newt- perch- heron
Water fleas, small fish, heron, and frog fox is a food chains in the above food web.
What is a food chain?The order of events in an ecosystem, in which one living organism eats another organism, and later that organism is consumed by another larger organism of called a food chain. This is the way the flow of nutrients and energy from one organism to another at different trophic levels in a food chain.
The feeding pattern or relationship between living organisms is the food chain. The sequential stages in a food chain, start with the producers at the bottom and are followed by the primary, secondary and tertiary consumers. Each of these levels in a food chain is known as a trophic level.
The food chain consists of the sun, which is the main source of energy. The producers, the consumers, and the decomposers.
Therefore, in this food web, water fleas, small fish, herons, and frog fox is a representation of a food chain.

describe what the function of a water cycle is
Answer:
Explanation:
The water cycle shows the continuous movement of water within the Earth and atmosphere. ... Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).
The water cycle is critical to the environment because water is required for photosynthesis, drinking, soil fertility, agriculture, and a variety of other functions. So maintaining the water cycle is important for the environment.
What is the water cycle?The water cycle is important for the environment because it changes water from a liquid to a gaseous state using sunlight, and when the gaseous form cools down, a cloud forms that will later form the water and return back to the earth. From the earth, the water is stored in the water sources and used by plants, animals, and humans for different purposes.
Hence, the water cycle is critical to the environment because water is required for photosynthesis, drinking, soil fertility, agriculture, and a variety of other functions. So maintaining the water cycle is important for the environment.

What if a mutation occurred in the human insulin gene and the first triplet was changed to C C G? Is this a silent mutation?
Yes, this will be a silent mutation.
Explanation: The mutation which occurred in the human insulin gene where the first codon was changed to CCG will be a silent codon because this will not change the sequence of the amino acid and the amino acids formed will remain the same.

This pedigree shows the inheritance Leber congenital amaurosis (LCA) which is a type of hereditary blindness. Individuals with this disease lose their vision during childhood. 3. What is the inheritance pattern shown?
About the question: You will find the pedigree in the attached files
Answer:
Autosomal recessive inheritance
Explanation:
Autosomal recessive inheritance characterizes by the expression of the recessive trait. Two copies of these alleles are needed to express the recessive phenotype and no dominant alleles.
Let us assume that the diallelic autosomal gene has a dominant allele L that expresses the normal phenotype and the recessive allele l that expresses the altered phenotype. The pedigree would be as shown in the attached files.
To interpret the pedigree, remember that
Squares represent malesCircles represent femalesEmpty figures express normal/healthy/not affected individualsSolid black figures represent affected individualsLeber congenital amaurosis (LCA) is a type of Autosomal recessive inheritance. Individual with this disease loses their vision during childhood.
What is Pedigree Analysis?The study of the inheritance of genetic traits in several generations of a human family in the form of a family tree diagram is called Pedigree analysis.
Two copies of these alleles are required to express the recessive phenotype and are responsible for the inheritance of LCA. As autosomal recessive inheritance expresses its trait when both the alleles of each parent are in recessive form and the resulted offspring shows the inheritance pattern.
Hence, LCA is an autosomal recessive inheritance caused by the expression of both recessive alleles simultaneously in an individual.

The photosphere and chromosphere are typically described by their visible
colors, such as red or yellow.
Chromosphere and photosphere are both layers of the Sun. The
photosphere is the visible surface of the sun which is characterized by a
yellow color.
The chromosphere is regarded as the layer found above the visible layer of
the sun(photosphere). They are made up of hydrogen and helium nuclei
which when ionizes produces a red color especially during an eclipse.
