I'll take a gander at your question

Explanation:

1) Illnesses can be caused by anything really, if you have a virus that promotes illness to you. It'll usually just be symptoms or some low classifying illness.

2) The Difference between Antibiotics and Antivirals is that antibiotics take care of your wounds and basic illnesses like pneumonia. Antibiotics just make sure that you don't get infections.

3) Antivirals are used to fight off viruses. Antivirals work by preventing the virus from spreading any further than it already has. An Antiviral allows the host to recover slowly, but not yet be cured.

4) The problem with Antivirals, is that they're not cures or vaccines, they're only made to fight off the affects of the virus.

5) Keep in mind that some viruses, bacterium or cells have adapted to certain Antibiotics or antivirals. This makes it hard to find what the host needs.

6) Your immune system, allows you to be responsive to viruses, infections and illnesses. To develop an Immune System, a child will be born. The parent will have to nurture and care for the child, as the child needs help building their immune system.

7) From here on out, your immune system is entirely built from getting Sick. Your immune system needs to recognize what affects it, so that you gain immunity.

8) Vaccines are basically cures, they are used to prevent Viruses, like your average flu shot. Take the shot, Skip a Sick Day

Explanation:

" Yes, dolphins can understand the difference between seeing another dolphin and seeing their own reflection.

Dolphins are highly intelligent marine mammals with sophisticated cognitive abilities. They possess a level of self-awareness that allows them to distinguish between their own reflection and another dolphin. This has been demonstrated through the mirror test, which is used to assess self-recognition in animals.

In studies where dolphins have been exposed to mirrors, they have shown behaviors indicating that they recognize themselves. For example, they may investigate parts of their bodies that they cannot see without a mirror, suggesting that they understand that the reflection is of themselves. This level of self-awareness is a strong indicator that dolphins can differentiate between their own image and that of another dolphin.

Furthermore, dolphins use echolocation to perceive their environment, which provides them with detailed information about objects, including other dolphins. They can discern the difference between the echoes returning from another living dolphin and those from an inanimate object or their own reflection.

Therefore, based on scientific evidence and observed behaviors, it is concluded that dolphins do understand the difference between seeing another dolphin and seeing their own reflection."

Answer:

According to the law of conservation of mass, there is a fixed amount of nitrogen on Earth. Nitrogen that exists in the air is fixed by nitrogen fixing bacteria in root nodules. This allows it to exist in the soil. Plants then use the nitrogen to make proteins and other complex compounds. When animals eat the plants, the nitrogen is then transferred to their bodies. When these organisms die, the nitrogen is broken down by decomposers and returned to the air by bacteria.

In the nitrogen cycle, nitrogen in the air is fixed by nitrogen-fixing bacteria, used by plants to make proteins, transferred to animals when they eat plants, and returned to the air by decomposing bacteria when these organisms die.

Answer:

The energy flows from one level to the another level in energy pyramid in the following form.

The first trophic level organisms are the plants. They are called producer because they produce food for themselves and for others from the process of photosynthesis. These plants are eaten by primary consumers i.e. herbivores and the energy which is present inside the plant is transfer to animals. Herbivores are eaten by secondary consumers i. e. carnivores. After that secondary consumers are the food of tertiary consumers.

No, all the matter and energy from one level doesn't transferred to the next level. 90 % of energy is lost as a heat energy and 10 % is transfered to next level.

The early solar system was an extremely violent place

Explanation:

The early solar system was a violent place: it wasn’t just asteroids, but whole planets that veered on strange courses. When most of us learn about the solar system, it seems like a pretty well-ordered place. Our Sun formed first, about five billion years ago, and the planets appeared a little later. It was a from the chaos in the solar system that an orderly planets which moved in orbits appeared.

Any star system is basically formed due to the vast disk of gas and in  the epicenter if the disk is the baby star formed. The star absorbs the majority of materials from the space in its disk but there are some remains too. These remnants coalesces into dust grains which becomes pebbles and as the time passes by it grows dense into boulders and into huge gigantic planets. This is how planets formed and according to physics, small planets have small orbits and moves closer to the sun.

Explanation:

Introns are deleted before a gene is transcribed from DNA to RNA because introns are non coding regions between exons their presence will interrupt the translation process.

Explanation:

Introns are the non coding regions on mRNA that are transcribed from a sequence of DNA. The introns are deleted by  RNA splicing and only exons are coded so that correct protein is formed otherwise introns would get coded along and wrong protein will be formed. Introns are present in eukaryotic cell.

Introns play a very important role in controlling gene expression. Multiple variant of a particular protein is controlled by introns. An error during splicing would cause a different protein to be code.

Introns are important because all the cells in eukaryotes have same group of genes and to prevent them in getting expressed in all the cells where they are not required.

Connection between:

1) Carbohydrate, Mitochondria

Mitochondria play a very critical role in the metabolism of carbohydrates, proteins and fats and energy production. This is due to the presence of enzymes like reductase, oxidase, hydroxylase which activates the metabolic reactions of the citric acid cycle and the oxidative-phosphorylation process in the mitochondria.

2) Endoplasmic reticulum, Ribosomes

Ribosomes get attached to the outer surface of the endoplasmic reticulum and change it to rough endoplasmic reticulum. This is done to facilitate transport of the synthesized protein from ribosomes to endoplasmic reticulum which further transports to other parts of the cell and also stores protein.  

3) Vacuoles, Organelles

Vacoules present in plant cells interacts with other cellular organelles of plants like the Golgi apparatus or the endoplasmic reticulum to aid in their functions. Vacoules interact with Golgi apparatus and facilities its lytic functions; with endoplasmic reticulum it helps in protein storage.

The most likely percentages for offspring of two red/white-feather chicken parents, given that red and white feathers exhibit codominance and both parents are RW, would be "25% red-feathered, 50% red/white-feathered ('speckled'), and 25% white-feathered".

The question is about the expected offspring percentages from a cross of two chickens with red and white feathers. A Punnett square can help predict the outcome of their offspring's feather colors. Here's how we would complete it:

We see that the offspring probabilities are as follows:

Therefore, the most likely percentages for offspring of two red/white (RW) feather chicken parents would be 25% white-feather chickens, 25% red-feather chickens, and 50% red/white-feather chickens.

Answer:

A: geomagnetic storm -- aurora

B: coronal mass ejection -- geomagnetic storm

Explanation:

A cause-effect relationship is one in which there is an underlying trigger for some observations. Here, the cause we are considering is the solar weather. Effect is on the earth's magnetosphere.

Solar weather are the spectacular effects of the sun. Some of these are the production of geomagnetic storm and coronal mass ejection.

A geomagnetic storm is a temporary event leading to the formation of Auroras. In this scenario, magnetic fields and solar winds from the sun interacts with the magnetosphere causing a geomagnetic storm which leaves trails of beautiful light in the sky.

A full blown geomagnetic storm results from coronal mass ejection by the sun. This is a massive release of plasma from the sun's corona region. These energized particles leads to a geomagnetic storm or solar storm as they interact with the earth's magnetosphere.

Answer:C) Traits like this are determined by the genes passed from parents to their children.

Explanation: Every trait in an organism is controlled by a pair of gene. A gene that controls a trait usually have two alleles. During fertilization, for every pair of gene one allele is inherited from the mother while the other allele is inherited from the father and the two alleles come together to form a pair of gene. Every trait in an organism is determined by genes that are passed from the parents to the offsprings.

Human activities drive the increase of carbon dioxide and other greenhouse gases in the atmosphere, especially through animal husbandry and changes to the natural world. These activities amplify the spread of infectious diseases and impact ecological stability, which in turn affects humanity's long-term sustainability.

Human activities such as animal husbandry, deforestation, and urban expansion into natural habitats significantly increase the occurrence and spread of infectious diseases, and amplify the already existing natural processes that add carbon dioxide (CO₂) and other greenhouse gases to the atmosphere. The large-scale raising of livestock contributes to increased levels of CO₂ and methane through digestion and farming practices, consequently affecting the biogeochemical cycles notably. Moreover, the movement of humans into previously undisturbed environments elevates the risk of transmitting disease-carrying organisms, thereby facilitating the emergence of infectious diseases that can impact wildlife, domestic species, and humans. Climate change, as a result of these activities, also plays a crucial role in altering ecosystems and may lead to potential ecological collapses which can affect the Earth's carrying capacity for human beings.

As the debates around increasing atmospheric carbon due to human activities like the burning of fossil fuels continue, scientists are also considering natural processes in their predictive models. It is noteworthy that human-induced changes extend beyond atmospheric carbon, contributing to ozone layer depletion, erosion from acid rain, and global climate change, all of which have profound consequences on the planet's long-term sustainability and capacity to support human life.

This SARS virus is transmitted in a manner most similar to the transmission of Influenza.

3. An animal can be both prey and predator.

A. All animal cannot only be one. Most animals are prey and predator in elaborate food webs.

B. Correct

C. Animals cannot just choose their spot in the food web. They need to hunt, and be hunted. Nature choses instead.

Final answer:

An animal can be both predator and prey in different contexts, exemplifying the intricate relationships in a food web. Predators and prey often have adaptive traits like camouflage for hunting or evasion. Few animals, like adult lions, may not have natural predators, but most are part of a complex predation hierarchy.

Explanation:

An animal can be both prey and predator, not just one or the other. Many animals, such as blue jays, are predators when they hunt insects but can become prey themselves when hunted by snakes. Similarly, snakes can fall prey to larger predators like hawks. This demonstrates a complex food web where energy transfers from one organism to another through predation. Predators may possess adaptations like camouflage, speed, and heightened senses to hunt effectively and evade becoming prey themselves.

Examples like the lion, sharks, or crocodiles are among the few predators at the top of their respective food chains and often have no natural predators once they reach adulthood. However, this doesn't mean they were never prey, as many would have been vulnerable when they were younger. Predation involves direct lethal interactions like a lion hunting a zebra, while herbivory involves organisms eating plants but not killing them, such as a zebra eating grass.

Answer:

There is inverse relationship between DDT use and bald issue reproduction

Explanation:

Dichlorodiphenyltrichloroethane, is commonly known as DDT, which is a colorless, tasteless, and almost odorless, crystalline chemical, an organochlor. Originally developed as an insecticide, it is famous for its environmental impact. DDT was synthesized first in 1874 by the Austrian chemist Othmar Zeidler. The breeding of bald eagles in northwest Ontario rose from 1.26 offspring per breeding area in 1966 to a low of 0.46 in 1974 and then rose to 1.12 in 1981. The DDE residues in the added eggs showed a significant inverse relationship, confirming the effects of toxin on population-level bald head reproduction and the effectiveness of the DDT ban. The recovery from DDE contamination in the bald eagle appears to be much faster than expected.

Explanation: RNA is found in all cells both prokaryotic and eukaryotic cells. RNA is a single stranded nucleic acid that contains the information for the production of proteins. There are three classes of RNA: messenger RNA, transfer RNA and ribosomal RNA, and they are all found in every living cell whether prokaryotic or eukaryotic cells.

Answer:

The ecosystem would collapse if producers were removed.

Explanation:

The primary consumers populating would decrease due to lack of food and if a species doesn’t have food they most likely won’t reproduce. The secondary consumers won’t have enough food either because their prey being the primary consumers would die off. All this leads to the down fall of ecosystem.

Removing either the producers or decomposers from an ecosystem will disrupt the balance of life. Producers provide energy for the food chain, while decomposers recycle nutrients back into the ecosystem. Without either of these, the ecosystem could collapse.

If either the producers or decomposers were removed from an ecosystem, it would drastically upset the balance of life. Producers, like plants, are the basis of the food chain, creating energy through photosynthesis. Without producers, consumers would not have a food source, leading to a potential collapse of the ecosystem. Similarly, decomposers play a vital role in breaking down dead organic material and recycling nutrients back into the ecosystem. Without decomposers, the build-up of dead matter could lead to diseases spreading, soil fertility would decrease, and the nutrient cycle would be disrupted.
