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

Answers

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.

Answers

Answer:

1).Erosion of rocks

Explanation:

Erosion of rocks has effect of hydrosphere on the lithosphere. When the river and streams passing through a region, the water eroded the rocks that comes in their way with the passage of time as well as the bank of the rivers. The speed of erosion depends on the speed of the flow of rivers because speedy flow of rivers causes fast erosion of rocks so we can say that the erosion is the main effect of hydrosphere on the lithosphere.

Mushrooms and yeasts reproduce by spores and are composed of cells enclosed by cell walls. These organisms fall into which kingdom?

Answers

Answer:

Fungi kingdom.

Explanation:

Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.

The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.

Kingdoms include different phyla closely related.

The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.

All the members of the kingdom

Lack mobility, growing on the ground, organic matter, or other surfaces. They all have a rigid cell wall composed of chitin. They grow like hyphae, which are cylindrical uniformed structures that might reach many centimeters in length.Heterotrophic nutrition. The species can not produce their own food, so they decompose organic matter and get the nutrients from there.Reproduction is by spores, which are resistant to adverse environmental conditions.

What was the discovery scientists made in the 1950's that led them to then accept Wegener's theory of Continental Drift?

Answers

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.

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?

Answers

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 individuals

Leber 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.

c. 50% DD and 50% dd
d. 25% DD, 50% Dd, 25% dd

Answers

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.

_______ 9.  A severe mutation may lead to cell death and may have no effect on the body.

_______ 10.  Most mutation are harmful.

Answer:

FalseFalseFalseFalseTrueTrueFalseTrueTrueFalse

Explanation:  

_False_1.  A molecular group consisting of a sugar molecule, a phosphate group, and a nitrogenous base is a nucleic acid.

Nucleotides: subunits or monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base. The chain or sequence of nucleotides composes the polymer. Different nucleotides joined by their extremes compose the nucleic acid: DNA or RNA.  

A molecular group consisting of a sugar molecule, a phosphate group, and a nitrogenous base is a nucleotide.

_False_ 2. In a DNA molecule, a base pair would be composed of adenine and guanine.

In the DNA molecule, Adenine (Purine) always pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. A-T pair is united by 2 hydrogen bonds, and the G-C pair is united by 3 hydrogen bonds.

In a DNA molecule, a base pair would be composed of adenine and timine, or In a DNA molecule, a base pair would be composed of cytosine and guanine.

_False_ 3.  Cytosine and adenine are purines.

Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.

Guanine and adenine are purines.

_False_ 4. During the replication of DNA, bonds are broken between the phosphate groups.

During the replication of DNA, bonds are broken between the hydrogen groups.

_True_ 5.  RNA contains the nitrogenous base uracil.

Instead of Timine, RNA contains uracil that pairs with adenine.  

_True_ 6. There are 20 different amino acids in a cell.

_False_ 7. The coded message carried by messenger RNA is translated into polypeptides at organelles called chloroplasts.  

When mRNA leaves the nucleus, meets a free ribosome in the cytosol. Into this organelle, it starts the protein building. Ribosomes read the mRNA code and begin protein synthesis by adding the correct amino acid using transference RNA.

The coded message carried by messenger RNA is translated into polypeptides at organelles called ribosomes.  

__True__ 8.  The decoding of a messenger RNA message into a polypeptide chain is known as translation

__True__ 9.  A severe mutation may lead to cell death and may have no effect on the body.

_False_ 10.  Most mutation are harmful.

A mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but most of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection, leading to evolution.

Most mutation are not harmful

Based on structure, DNA molecules are composed of nucleotides and mutations in DNA are mostly harmful.

What is DNA?

DNA refers to sequences of nucleotides which contain the genetic information of organisms.

Nucleic acids are chains of nucleotides.

Nucleotides are molecular group consisting of a sugar molecule, a phosphate group and a nitrogenous base.

Four nucleotides are present in DNA and they include:

adenine guanimecytidine andthymidine

In a DNA molecule, a base pair would be composed of adenine and guanine is false because adenine bonds to thymine, while guanine bonds to cytidine

Cytosine and adenine are purines is false because cytosine is pyrimidine while adenine is a purine

During the replication of DNA, bonds are broken between the phosphate groups is false because the bonds broken are hydrogen bonds.

RNA contains the nitrogenous base uracil is true as uracil is found in RNA in place of thymine in DNA.

There are 20 different amino acids in a cell is true as these amino acids are found in proteins.

The coded message carried by messenger RNA is translated into polypeptides at organelles called chloroplasts is false because protein synthesis occurs at the ribosomes.

The decoding of a messenger RNA message into a polypeptide chain is known as translation is true.

 A severe mutation may lead to cell death and may have no effect on the body is false because mutations can cause death of organisms.

Most mutation are harmful is true because only free mutations are beneficial.

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?

Answers

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).
