construct a scientific explanation using claim, evidence, and reasoning to help explain why Burchell’s zebras are making such a long migration during specific months of the year.

Answers

Answer 1

Claim: Burchell's zebras are making a long migration during specific months of the year in order to obtain available food and water sources.

What evidence explain why Burchell’s zebras are making such a long migration during specific months of the year?

The evidence that explains why Burchell’s zebras are making such a long migration during specific months of the year is that during the dry season, vegetation is scarce, and water sources are limited. Therefore, Burchell's zebras migrate to find suitable food and water sources.

The reasoning behind this is that the migration in order to survive of Burchell's zebras is evidence of their evolution to survive in their specific environment.

Why is expressed sequence tag library a fitting name for a collection of clones made from mRNA?
please help :((((

Answers

An expressed sequence tag (EST) library is a collection of short cDNA (complementary DNA) sequences that are generated from the mRNA (messenger RNA) of an organism. The name "expressed sequence tag" is fitting because these short sequences are "tags" that identify the expressed genes in a particular cell or tissue.

The term "expressed" refers to the fact that the mRNA is transcribed from a gene and has therefore been "expressed" or made into RNA. The term "sequence" refers to the fact that the cDNA sequences are determined by sequencing the mRNA. Finally, the term "tag" refers to the fact that the ESTs are short sequences that can be used to identify expressed genes in a particular cell or tissue.

Therefore, the name "expressed sequence tag library" is fitting for a collection of clones made from mRNA because it accurately describes the nature and function of the library.

Based on the figure of differential gene expression shown:

Bicoid does not have any effect on the expression of Caudal.Nanos decreases the expression of Hunchback.

What is the strategy being used to initiate differential gene expression here?

The strategy being used to initiate differential gene expression in the developing fly larva is the establishment of morphogen gradients.

These gradients determine the spatial pattern of gene expression, leading to the formation of different cell types along the anterior-posterior and dorsal-ventral axes of the larva.

The genes coding for the mRNAs for Bicoid, Caudal, Nanos, and  Hunchback are differentially expressed.

Origin; Silt suspended in the water surrounding a coral reef near the coast of a small island community in the Caribbean Sea, Effect on one organism; Silt suspended in the water can have negative effects on the coral reef ecosystem. and Effect on humans; The silt suspended in the water can also have negative effects on humans.

Effect on one organism; Silt suspended in the water can have negative effects on the coral reef ecosystem. Silt can reduce the amount of light available to the coral and other photosynthetic organisms, hindering their ability to produce energy through photosynthesis. Additionally, silt can clog the coral's feeding and respiratory structures, causing them to starve or suffocate.

Effect on humans; The silt suspended in the water can also have negative effects on humans. Silt can reduce the water quality, making it cloudy and turbid, and reducing visibility for swimmers, divers, and snorkelers. Silt can also smother and kill seagrasses and other plants, which provide important habitat and food for fish and other marine animals, potentially reducing the amount of seafood available for human consumption.

Alleles are different gene forms that share the same location on a chromosome and regulate the same trait. An individual can have two alleles (one from each parent) for each gene, and they can be dominant or recessive.

This cross would not produce any white short-eared sheep. Either the long-eared offspring would be white or the short-eared offspring would be black. The cross shows that about 100 of the white short-eared sheep would be produced.

Answers

1. Newton's first law of motion projects that a object at rest will remain at rest, and a object in motion will remain in motion with a constant velocity, until or unless a force is acted upon by the external environment.

2. Newton's second law of motion projects that the acceleration of an object is considered to be directly proportional to the net force acting on the object and generally inversely proportional to its mass.

3. Newton's third law of motion projects that for every action, there is an equal and opposite reaction.

The first law is also renowned as the law of inertia. The second law thoroughly distinguishes the relationship between applied force and the rate of change of momentum. And finally the third law is also know as  the law of action and reaction because it depends on the type of stimulus that is experienced from the environment when the individual is applying force.

what is the basic concept behind relative age dating of fossils a the Upper Rock layers were deposited earlier in the Lower Rock layers b the Lower Rock layers were deposited earlier than the Upper Rock layers c the older fossils contain relatively higher levels of radioactive d the younger fossils contain relatively higher levels of radioactive isotopes in the older fossils ​

Answers

The basic concept behind relative age dating of fossils is that the Lower Rock layers were deposited earlier than the Upper Rock layers. This is because the principle of superposition states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are at the bottom, and the youngest rocks are at the top. As a result, fossils found in the lower layers are generally older than those found in the upper layers. This method of dating does not rely on measuring radioactive isotopes or other methods that require absolute dates, but rather on the relative position of the fossils within the layers of rock.

What structure do fish lose that other vertebrates keep?

Answers

Aquatic vertebrates such as fish have developed special adaptations to live in water. Loss of a bone component in their ears known as the "labyrinthine apparatus" is one of these adaptations.

All other vertebrates have this structure, which serves as a sound wave detector and aids in balance and orientation. However, in fish, a more straightforward system of canals filled with fluid and sensory cells has taken the place of this structure.

It is believed that fish evolved without the labyrinthine apparatus to lighten the weight of their heads and increase swimming efficiency.

Fish have evolved various adaptations, such as specialised sense organs and lateral lines, to navigate and live in their aquatic environment despite the absence of this structure.

Leopards have spots to blend in with the patches of sunlight on the jungle floor.
How might a trait like spots become more common in a population of leopards?

A. Leopards get their spots by rubbing against each other. Eventually all leopards
in a population will have spots.

B. Blending in helps leopards successfully hunt for food. Leopards with more food
are more likely to survive and pass on their spotted trait to offspring.

C. An adult leopard develops more spots during its lifetime in order to compete
with other leopards.

Answers

Option B is the most likely to result in the increased prevalence of spots in a population of leopards. This is because natural selection favors traits that provide a survival advantage. In the case of leopards, having spots helps them blend in with their environment and become better hunters, which increases their chances of survival and reproduction. Over time, this can lead to the spotted trait becoming more common in the population, as individuals with the trait are more successful at passing it on to their offspring.

B is the correct answer. Adaptations that allow animals to survive in an environment are more favored and they will live to pass those traits onto their offspring
