1. How do you get your zenith distance from the altitude of the Sun at solar noon?
2. How do you get your latitude from your zenith distance and the Sun's declination?
Answer: The zenith angle is the angle between the sun and the vertical. The zenith angle is similar to the elevation angle but it is measured from the vertical rather than from the horizontal, thus making the zenith angle = 90° - elevation.
Since it is South of the Zenith, we add the zenith distance to the declination to find our latitude: our latitude = the declination + the zenith distance = -17° + 39° = +22° (North latitude).

What is Crossing over
Answer:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

What genotypes are observed when you cross a Dd parent
with another Dd parent?
a. 100% DD
b. 75% DD and 25% dd
c. 50% DD and 50% dd
d. 25% DD, 50% Dd, 25% dd
Answer:
it is D. 25%DD ,50%Dd ,25%dd
If both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd. So, the correct option is D.
What do you mean by genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for our study.
Here, both the parents carry the genotype Dd, when Dd is crossed with Dd, the resulting offspring are 1DD, 2Dd, and 1dd.
Therefore, if both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd.

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.

Explanation:
As I think Stroma and granum are the correct answer.
There are two distinct regions present inside a chloroplast known as the grana and stroma. Grana are made up of stacks of disc-shaped structures known as thylakoids. The grana of the chloroplast consists of chlorophyll pigments and are the functional units of chloroplasts.
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.

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.
