Why nematodes are called pseudo coelomates?

Answers

Answer 1

Answer:

Nematodes are referred to as "pseudocoelomates" since their coelom is not entirely lined with mesoderm ally cell - derived in most forms, and they are triploblastic.

What is a nematode?

Any unsegmented worm of the phylum Nematoda, having an elongated, cylindrical body; a roundworm

What are characteristics of the pseudocoelomate phylum?

-bilateral symmetry, unsegmented, triploblastic

-body cavity a pseudocoel

-size: some microscopic, others a few meters in length

-body veriform

-complete gut (2 cavities)

The structure of the body wall of pseudocoelomates explained:

-muscles are longitudinal (no circular) beneath the hypodermis

5. What are virus hoaxes? Why are the hoaxes sometimes more dangerous than an actual virus?

Answers

Answer:

An actual computer virus is a malicious software, often known as malware, that can harm a computer and its users.

Virus hoaxes are false or misleading information about viruses that circulate through various communication channels.

They can be more dangerous than actual viruses due to their ability to spread quickly, cause panic, and undermine effective public health measures.

Virus hoaxes are deceptive messages or claims that often exaggerate the severity or impact of a particular virus. They can be spread through social media, email chains, or word of mouth. These hoaxes may include misinformation about symptoms, transmission methods, or false remedies, leading people to take ineffective or even harmful actions.

What makes virus hoaxes particularly dangerous is their potential to create panic and misinformation at a rapid pace. The viral nature of social media and other communication platforms allows these hoaxes to reach a wide audience within a short period. As a result, people may make decisions based on false information, such as avoiding necessary medical treatment, taking unnecessary precautions, or spreading fear and misinformation to others.

Moreover, virus hoaxes can undermine public health efforts by diverting attention and resources from legitimate preventive measures. They can erode trust in healthcare authorities and disrupt the dissemination of accurate information, making it harder for individuals to make informed decisions and follow recommended guidelines.

This can have severe consequences, especially during outbreaks or pandemics, where timely and accurate information is crucial for public safety. Therefore, it is essential to verify the credibility of information and rely on trusted sources to mitigate the risks associated with virus hoaxes.

I need the description of Native species: Koala

(explain the species niche and how it inpacts the ecosystem)

Answers

The Koala (Phascolarctos cinereus) is a native species of Australia that belongs to the marsupial family Phascolarctidae. Koalas are known for their distinctive appearance, including their large ears, round faces, and fluffy, gray-brown fur.

Koalas have a specialized niche in their ecosystem, as they are highly specialized herbivores that feed exclusively on eucalyptus leaves. They have a long, sticky tongue that allows them to extract nutrients from the leaves, and they have a unique digestive system that is able to process the toxic compounds found in eucalyptus leaves.

The Koala's niche has a significant impact on the ecosystem. Eucalyptus leaves are an important food source for many other animals, including birds and insects, so the Koala's feeding habits help to maintain a balance in the ecosystem.

Additionally, Koalas play a role in seed dispersal, as they often defecate the seeds from eucalyptus leaves in their feces, which helps to spread the seeds and promote new growth.

Overall, the Koala's niche as a specialized herbivore that feeds on eucalyptus leaves is important for maintaining the health and balance of their ecosystem, and it helps to support the survival of many other species in the region.

If all humans share 95. 5% or more of their dna, how can a dna fingerprint differentiate between 2 people?

Answers

A DNA fingerprint uses specific regions of the DNA that vary between individuals, such as short tandem repeats (STRs), to differentiate between two people.

DNA fingerprinting, also known as DNA profiling, is a technique that analyzes specific regions of an individual's DNA to create a unique profile. Although humans share a high percentage of DNA with one another, there are still differences in the genetic sequences within certain regions of the genome. These differences, known as polymorphisms, are the basis for DNA fingerprinting. By analyzing these polymorphisms, forensic scientists can differentiate between individuals and exclude others who do not share the same DNA profile.

There are several types of polymorphisms that can be used in DNA fingerprinting, including short tandem repeats (STRs) and single nucleotide polymorphisms (SNPs). STRs are repeating sequences of DNA that vary in length between individuals. SNP's are single nucleotide variations in the genetic code that can be used to identify specific genetic markers. The combination of these polymorphisms provides a unique genetic profile for each individual, which can be used for identification purposes.

Overall, DNA fingerprinting is a highly accurate method for identifying individuals, as the probability of two unrelated individuals sharing the same DNA profile is extremely low. Despite the high percentage of shared DNA among humans, the small differences in genetic sequence are enough to create a distinct genetic profile for each individual.

ecosystem services:

Answers

Answer:

5

Explanation:

jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj

Answer:

Explanation:

Ecosystem services, outputs, conditions, are processes of natural systems that directly or indirectly benefit humans or enhance social welfare. Ecosystem services can benefit people in many ways, either directly or as inputs into the production of other goods and services. For example, the pollination of crops provided by bees and other organisms contributes to food production and is thus considered an ecosystem service. Another example is the attenuation of flooding in residential areas provided by riparian buffers and wetlands.

Two criteria distinguish ecosystem services from other ecosystem conditions or processes. First, an ecosystem service must be linked to an identifiable set of human beneficiaries. The service can be an aspect or consequence of an ecological condition and can directly or indirectly benefit or profit the beneficiaries. Second, physical and institutional access constraints must not prevent people from realizing those benefits. For example, increases in fish abundance can enhance the welfare of those engaged in commercial or recreational fishing, but only if those increases occur in areas where fishing occurs. Conditions or processes of ecosystems that cannot be linked to the welfare of identifiable beneficiary groups are not ecosystem services. For example, changes in fish abundance in areas not used by humans and that have no direct or indirect effect on human benefits are not ecosystem services.

what type of inter-molecular force arises from instantaneous dipole moments?

Answers

The intermolecular force that arises from instantaneous dipole moments is called the London dispersion force. This force is also sometimes referred to as induced dipole-induced dipole or van der Waals force.

What is an intermolecular force?

An intermolecular force is a force that exists between two molecules. These forces hold molecules together in a solid or liquid state. Three types of intermolecular forces exist, namely: London dispersion forces: As mentioned above, these forces are caused by temporary dipoles in molecules. They are the weakest intermolecular force.

What are Dipole-dipole forces?

These forces occur between molecules that have a permanent dipole moment. Hydrogen bonding is a type of intermolecular force that occurs between molecules that contain hydrogen atoms bonded to oxygen, nitrogen, or fluorine. London dispersion forces are the only intermolecular forces that arise from instantaneous dipole moments.

What is a dipole moment?

A dipole moment occurs when a molecule has a separation of charge. In other words, one part of the molecule is slightly negative while the other part is slightly positive. This occurs when there is a difference in electronegativity between the atoms in the molecule. The dipole moment is the measure of the strength of the separation of charges. A larger dipole moment means a stronger separation of charges.

Proteins are synthesized: Group of answer choices Amino to carboxy terminal 3'-to-5' Carboxy to amino terminal 5'-to-3'

Answers

Proteins are synthesized from the N-terminus to the C-terminus. This is also known as the amino (N-) terminus to the carboxyl (C-) terminus.

The correct option among the given alternative is "amino to carboxy terminal".

Explanation:

DNA instructions are transformed into the amino acid sequence of a protein through a process known as transcription and translation, which occurs in the ribosome. The N-terminus and C-terminus of a protein are the two endpoints. The N-terminus of a protein contains the first amino acid in the sequence, which is often referred to as the start methionine. The C-terminus of a protein contains the last amino acid in the sequence. The end of the polypeptide chain is referred to as the carboxy terminus. The amino acid sequence of a protein is determined by the sequence of nucleotides in the mRNA molecule. This sequence is read in sets of three nucleotides, known as codons. Each codon specifies a particular amino acid to be added to the growing polypeptide chain. The process of protein synthesis always starts at the N-terminus, where the first amino acid is attached, and ends at the C-terminus, where the last amino acid is attached. Therefore, proteins are synthesized from the amino to carboxy terminal end.
