in 3-5 sentences describe how pond ecosystems are impacted by an increasing level of carbon dioxide in the atmosphere
Answers
Increasing levels of carbon dioxide can affect the pH of the pond ecosystem.
As carbon dioxide (CO₂) levels in the atmosphere rise, more CO₂ gets absorbed into seawater. As a result, the world's oceans have grown more acidic over time, causing a wide range of well-documented problems for marine animals and pond ecosystems. Now, researchers present some of the first evidence that similar things are happening in freshwaters too.

Assignment 1: Evidence for Evolution
Patterns based on observations of fossils:
[Example:] The observation made by Darwin that living species of armadillo can be found in the same area of Argentina where fossils of extinct glyptodonts were reported. Both species are very similar, with the glyptodon being like a giant armadillo. This observation can be explained if the two species are evolutionary related, thus belonging to the same lineage of species but with modifications.

Answers
The distribution of organisms provides evidence for evolution through patterns observed in geographic distribution, endemic species on islands, and changes in distribution seen in the fossil record.
Observations regarding the distribution of organisms provide valuable evidence for evolution. One such pattern is the geographic distribution of species. Similar environments often contain distinct yet closely related species. This can be observed in different regions around the world.
For example, the marsupials in Australia, such as kangaroos, koalas, and wombats, show remarkable similarities in their reproductive and developmental characteristics. These similarities suggest a common ancestry and adaptive radiation in response to the unique Australian environment.
Another significant observation is the presence of endemic species on islands. Islands provide isolated habitats, allowing for unique evolutionary processes to occur. The Galapagos Islands, famously studied by Darwin, exhibit an array of species found nowhere else on Earth.
The finches he observed there had different beak shapes and sizes, each adapted for specialized feeding habits. This diversification is thought to have occurred through natural selection acting on a common ancestor.
Furthermore, fossil records indicate that the distribution of organisms has changed over time. For instance, the discovery of similar fossils in South America and Africa suggests that these continents were once connected, supporting the theory of continental drift and explaining the presence of related species in both regions.

each of the three cell layers became different parts of the adult organism. what does that mean about the cells that were once identical?
Answers
The cells that were once identical have undergone differentiation, giving rise to distinct cell types in different cell layers.
The way that every one of the three cell layers became various pieces of the grown-up creature proposes that the cells that were once indistinguishable have gone through separation, a cycle by which cells with indistinguishable hereditary material form into various cell types with unmistakable primary and utilitarian qualities. During the beginning phases of early stage improvement, cells go through a course of specialization and separation, which includes changes in quality articulation and the reception of explicit morphological and utilitarian highlights. These separated cells then, at that point, bring about the various tissues, organs, and designs of the grown-up living being. This course of separation is essential for the appropriate turn of events and working of the creature.

What is elastic connective tissue?
Answers
Elastic connective tissue is a type of connective tissue that provides support and elasticity to various tissues and organs in the body. It is composed of long, flexible, and elastic fibers known as elastin
explain about elastic connective tissue ?
Elastic connective tissue is found in many different structures in the body, including the walls of large arteries, the bronchial tubes in the lungs, the walls of the vocal cords, and the skin. Its elasticity allows these structures to stretch and then return to their original shape, which is important for their proper functioning.
For example, in the walls of large arteries, the elasticity of the elastic connective tissue allows the blood vessels to dilate and contract with each heartbeat, which helps to regulate blood flow and blood pressure. In the lungs, the elasticity of the bronchial tubes helps to regulate air flow and volume during breathing. And in the skin, the elastic connective tissue helps to maintain skin's resilience and elasticity, preventing it from becoming saggy or wrinkled.
In summary, elastic connective tissue is a critical component of many tissues and organs in the body, playing an important role in maintaining their structure, function, and overall health.

If a substance weighs 2.00 grams and you need the mass in kilograms, will the number appear to become smaller or larger?
Answers
Answer:
The number will appear smaller
Explanation:
Grams and Kilograms are two units of measuring the weight of substances. These two units are interchangeable/interconvertible.
One kilograms of a substance contains 1000 grams of that substance (kilo=thousand). Hence, for a substance weighing 2.00grams whose weight measurement is needed in kilograms, it will be converted by dividing the weight in grams by 1000.
That is, 2.00g/1000 = 0.002kilograms or 2.00 × 10^-3kg. According to the number after conversion, it appeared SMALLER because the kilograms (kg) is a bigger measurement compared to the grams (g).

Transcription is mRNA synthesis, which occurs by complementing a segment of the DNA template strand. The translation is the protein growth, which occurs by adding amino acids coded by mRNA codons. C) the polypeptide is 6 amino acids long.
What are transcription and translation?The whole process of protein synthesis includes Transcription and translation.
TRANSCRIPTION
Transcription is the mRNA synthesis process and occurs in the nucleus.
The DNA template strand is read in direction 3'→ 5' to build the mRNA molecule in direction 5'→ 3'. The template strand is the one that is going to be complemented by the mRNA.
mRNA molecule has the same sequence as the DNA coding strand, but it carries uracil instead of thymine.
TRANSLATION
Translation is the process through which polypeptide grows. It occurs in the cytoplasm.
rRNA and tRNA read mRNA in the direction 5'→ 3' and add the correct amino acids to build the new protein.
Amino acids are coded by mRNA codons. Protein synthesis initiates in the AUG start codon -Metionin- and ends when reaching either of the stop codons UAA, UAG, or UGA.
In the exposed example, we have a DNA strand. We know that it is the coding strand, so it has the same sequence as mRNA molecule.

imagine that in humans hair type is controlled by incomplete dominance. what is the phenotype of a person that has a genotype rc
Answers
Incomplete dominance is a genetic concept that involves the manifestation of a trait that is an intermediate between the phenotypes of the parents. In humans, the type of hair is controlled by incomplete dominance. The phenotype of a person that has a genotype rc is wavy hair.
Hair type in humans is not controlled by a single gene. However, it is controlled by a complex of several genes.
In incomplete dominance, an offspring that is heterozygous for a certain trait expresses a phenotype that is intermediate between the phenotypes of the two homozygous parents. This means that both alleles of the gene are expressed, but the expression is reduced by a certain degree so that the offspring does not fully express the dominant allele.
it can be said that the type of hair in humans is controlled by incomplete dominance. This means that a person may express wavy hair if they have an rc genotype.
Wavy hair is an intermediate phenotype that is expressed when an offspring is heterozygous for the hair type gene. It is not a straight hair phenotype, which is the result of the homozygous dominant allele, nor is it a curly hair phenotype, which is the result of the homozygous recessive allele. The heterozygous rc genotype results in the expression of both alleles but with reduced expression of the dominant allele.

our respiratory surface is covered with which cells that allow oxygen and carbon dioxide to exchange?
Answers
our respiratory surface is covered with cells that allow oxygen and carbon dioxide to exchange called as Alveoli
Specialized cells known as alveoli cover the respiratory surface. The lungs' alveoli, which resemble tiny sac-like structures, are in charge of allowing gas exchange between the bloodstream and the air. A thin layer of cells called epithelial cells that are permeable to oxygen and carbon dioxide lines the inside of them. As a result, carbon dioxide, a byproduct of cellular respiration, can diffuse out of the bloodstream and into the air, allowing oxygen from the air that has been inhaled to enter the bloodstream. Maintaining adequate oxygenation of the body's tissues and carbon dioxide elimination depend on the efficient exchange of gases at the alveoli. Surfactant is the fluid that lines alveoli. This liquid helps keep the air sac open and in shape so that oxygen and CO2 may travel through.

A locus that shows a 100% association with fur color is known as the "Fur color gene." The Fur color gene is the gene responsible for determining the color of an organism's fur, hair, or skin. Mutations in this gene can lead to variations in fur color. For example, in mice, the agouti gene is located on chromosome 2 and is responsible for determining the color of the mouse's fur. The presence of a dominant form of the agouti gene results in a yellow coat color, while the recessive form of the agouti gene produces a black coat color.
