What is an adaptation? Give an example of one.
Answer:
Adaptations are special skills that help animals survive in their environments. For example, in order for pelicans to catch their prey, they use their pouch-like beaks to scoop up fish. This is an example of physical adaptation; the animal is using its body parts to help it survive.

The principal enzyme involved in DNA replication is called _____________. The enzyme joins ________________ to synthesize a new _______________ strand of DNA. DNA replication is called ______________ because each new DNA molecule is made up of one original and one new strand.
complementary
DNA polymerase
nucleotides
semiconservative
Answer:
The principal enzyme involved in DNA replication is called _DNA polymerase_. The enzyme joins _nucleotides_ to synthesize a new __complementary_ strand of DNA. DNA replication is called __semiconservative__ because each new DNA molecule is made up of one original and one new strand.
Explanation:
DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.
DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.
The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated. Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.
DNA strands are antiparallel, and replication occurs only in 5´-3´direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.
Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

B

Answer:
A
Explanation:
A rare orchid has been found in the mountains in China.
The orchid has pale yellow flowers.
DNA analysis of the genome shows that it is an ancestral species.
All other present day orchids evolved from this ancestral species millions of
years ago.
One present day species has bright purple flowers.
Describe how an orchid with bright purple flowers may have evolved from the
ancestral species which has pale yellow flowers.
[4 marks]
Answer:
a mutation in the germinal line changed the phenotype to bright flowers which were capable of attracting more pollinators compared to yellow flowers. Subsequently, this mutation was selected by natural selection, thereby increasing its frequency in the population
Explanation:
A mutation is any change in the nucleotide DNA sequence of the genome of a particular organism. Mutations can be divided into 1-germinal mutations (i.e., mutations that occurred in the gamete cells) which can be passed on to offspring, and 2-somatic mutations (i.e., mutations that occurred in the somatic cells), which cannot be inherited. Moreover, mutations can be neutral, deleterious or beneficial depending on the environment in which the organism lives. When a germinal mutation is beneficial, the organism carrying the mutation will have more chances to survive and reproduce (i.e., a higher adaptive fitness), thereby the organism will have more chance to pass this mutation to the next generation and the mutation will increase its frequency in the population.
In an example of natural selection, ______ cells in cancerous tumors can survive chemotherapy, and these cells go on to divide rapidly in the absence of competition from other cells.

Explain why it is important to prevent the extinction of species?
Answer:
Animals and plants depend upon each other, so the loss of one species affects others within that complex web of relationships.
Explanation:
Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart.

Answer:
Why is it so critical that we protect species? 1. Its ecological significance. Plant and animal species are the cornerstones of healthy ecosystems. When a species becomes endangered, it indicates that the ecosystem is deteriorating.

a. wood
b. pith

Which of the following examples is NOT classified as composite volcano?
A. Mt. Fuji B. Mt. Rainier C. Mt. Mayon D. Mt. Paricutin
Answer:
C. Mt. Maton
Explanation:
not sure but hope it helps
Mt. Mayon examples is NOT classified as composite volcano.
What is Composite volcano?Cone-shaped composite volcanoes, also known as stratovolcanoes, are formed from numerous layers of lava, pumice, ash, and tephra. Composite volcanoes typically generate tall peaks rather than rounded cones because they are composed of layers of viscous material rather than fluid lava.
Calderas are occasionally created when the peak crater collapses. The most destructive volcanic eruptions in recorded history have been caused by composite volcanoes.
Apart from Earth, Mars is the only known location in the solar system with stratovolcanoes.
Therefore, Mt. Mayon examples is NOT classified as composite volcano.

What does every living thing have to have? *
Chloroplast
Nucleus
DNA
Answer:
DNA
Explanation:
Answer:
Explanation:
Los cloroplastos son los orgánulos celulares que en los organismos eucariotas fotosintetizadores se van ocupando de la fotosíntesis. Están limitados por una envoltura formada por las dos membranas concéntricas y contienen muchas vesículas, los tilacoides, donde se encuentran organizados los pigmentos y demás moléculas que convierten la energía lumínica en energía química, como la clorofila.
El término cloroplastos sirve alternativamente para designar a cualquier plasto dedicado a la fotosíntesis, o específicamente a los plastos verdes propios de las algas verdes y las plantas. Aunque el reciente descubrimiento adiciona a más individuos en la lista, como lo es en el caso de Elysia chlorotica, que al digerir al alga Vaucheria litorea, adquiere los cloroplastos a sus tejidos, y gracias a esto, puede realizar la fotosíntesis.
Possible variations of a gene that controls a specific trait
A) Heredity
B) Phenotype
C) Gene
D) Allele
Answer:
D
Explanation:
Alleles are the different possibilities for the trait (brown, blue, green.)
Possible variations of a gene that controls a specific trait are referred to as alleles. Therefore, the correct option is D.
Alleles are different types or forms of a gene that reside at the same locus on a certain chromosome. They contribute to the wide variety of traits seen within populations and can exist in several forms, such as dominant or recessive.
For example, there may be alleles for blue eyes, brown eyes, or green eyes, for a gene that affects eye color. Different alleles play a role in the variety of phenotypes (observable characteristics) that people can display.
Therefore, the correct option is D.
