The correct option regarding sea anemones is (b) i.e. None of the other given options of answer is correct. The order Actiniaria contains several marine creatures, including sea anemones. They resemble anemones, a kind of terrestrial plant, in look and name.

There is no free-swimming medusa stage in sea anemones. Invertebrates of the order Actiniaria that are predatory in the sea include sea anemones. The eggs and sperm produced by the polyp itself are fertilised to create a planula larva. It immediately grows into polyps. They are capable of having both sexual and asexual offspring. They are unable to produce their own food or engage in photosynthesis. As a result, sea anemones and single-celled algae form facultative mutualistic partnerships. The oral disc and tentacles are home to the algae, which are exposed to sunlight and protected from other feeders. The algae provide the sea anemones with food and oxygen. The stinging cells also protect the algae, making it less likely that herbivores would eat them up.

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.

The hormone that works to inhibit FSH and LH release is estrogen. Estrogen is a female sex hormone that is produced primarily by the ovaries. It plays a critical role in regulating the menstrual cycle and reproductive function in women.

Estrogen acts on the pituitary gland to inhibit the release of FSH and LH, which are hormones that stimulate the ovaries to produce eggs and release them during ovulation. This feedback mechanism helps to maintain a balance of hormones in the body and prevent overstimulation of the ovaries. In addition to estrogen, other hormones like progesterone and testosterone also play important roles in regulating reproductive function, but they do not have a direct inhibitory effect on FSH and LH release. Overall, estrogen is a key hormone that helps to regulate fertility in women and maintain a healthy reproductive system.

Answer:

Nucleus

Explanation:

Nucleus stores DNA

Answer:

The first way is when cells grow old or become damaged, they die, and new cells take their place. Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn't, when this happens it is usually noncancerous (benign). The second way is when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, when this happens more often then not the tumor is usually cancerous.

Answer: 1,000kcal

10% of 10,000 is 1,000.

The amount of energy transferred if 10% is transferred to the primary  consumers is 1000kcal

Given the following parameters

Amount of kcal the producer have = 10,000kCal

Percentage transferred to the primary consumers = 10% of the amount produced

Get the amount of energy transferred;

\(Energy \ transferred = \frac{10}{100} \times 10,000\\ Energy \ transferred =0.1 \times 10,000\\Energy \ transferred =\frac{10,000}{10}\\Energy \ transferred =1000kcal\)

Hence the amount of energy transferred if 10% is transferred to the primary consumers is 1000kcal.

If you planted a handful of basil seeds in a pot where phosphorus (not light) was the limiting resource, those basil plants are likely to allocate most of their resources into their roots.

This is because roots are responsible for nutrient absorption, and the plants would prioritize developing their root systems to access more phosphorus. Basil plants are likely to put most of their resources into their roots if you planted a handful of basil seeds in a pot with phosphorus as the limiting resource. Basil plants will be more successful in survival and reproduction if they allocate more of their resources to root systems to absorb nutrients and water from the soil. When plants are deprived of essential nutrients, such as phosphorus, they prioritize the allocation of available resources.

This results in the development of smaller or fewer leaves, which restricts photosynthesis, a fundamental physiological process that plants require to generate energy for growth, reproduction, and survival.

Hence , basil plants are likely to allocate most of their resources into their roots if you planted a handful of basil seeds in a pot with phosphorus as the limiting resource.

The best definition of homeostasis is **option (e)**: to maintain a relatively constant internal physiological environment regardless of the changes in the external environment.

Homeostasis refers to the ability of an organism or system to regulate and maintain internal stability and balance. It involves a dynamic process of monitoring and adjusting various physiological parameters to keep them within a narrow range suitable for optimal functioning. While the other options mention specific aspects or outcomes related to homeostasis, they do not encompass the comprehensive nature of the concept.

Option (a) refers to temperature regulation during hibernation, which is a specific instance of maintaining homeostasis but does not capture its broader scope. Option (b) focuses on the metabolic rate in varying environmental temperatures, which is a part of thermoregulation but not the sole aspect of homeostasis. Option (c) mentions vital organs but does not encompass all physiological systems. Option (d) suggests uniform metabolic rates among all cells, which is not always the case as different cells have specific functions and metabolic demands.

In summary, option (e) provides the best definition as it captures the essence of homeostasis, which is the maintenance of a relatively constant internal physiological environment despite external changes.

Yes, the rat liver supernatant contains enzymes that convert substance X to a mutagen, and his+ revertant occur.

The Ames test is a popular method for detecting if a certain chemical may cause mutations in the test organism's DNA. It is a biological experiment performed to examine chemical compounds' mutagenesis potential.

The Ames test employs different strains of the bacterium Salmonella typhimurium that have mutations in histidine synthase genes. These strains are auxotrophic mutants, which means they need histidine to thrive but can't make it.

The approach assesses the tested substance's potential to induce mutations that result in a return to a "prototrophic" state, allowing the cells to thrive on a histidine-free media.

Larger creatures, such as mammals, contain metabolic mechanisms that might possibly convert a chemical that is not mutagenic into one that is, or a chemical that is mutagenic into one that is not.

To more successfully assess a chemical compound's mutagenicity in relation to bigger species, rat liver enzymes can be introduced in an attempt to reproduce the Ames Test's effect on the substance being studied.

Optionally, rat liver extract is added to replicate the impact of metabolism, as some chemicals, such as benzo[a]pyrene, are not carcinogenic in and of themselves, but their metabolic products are. On an agar plate, the bacteria are distributed with a little quantity of histidine.

This modest quantity of histidine in the growing medium permits the bacteria to thrive and mutate for an initial period of time.

When histidine is reduced, only bacteria that have evolved to make their own histidine will survive. For 48 hours, the dish is incubated. A substance's mutagenicity is proportional to the number of colonies seen.

Spindle fibers that are connected at the kinetochore of the chromosomes shorten and pull the chromatids to the sides of the cell during Anaphase.

Microtubules, which grow from the two centrioles present inside the centrosome, are what makeup spindle fibers. In the cell cycle's synthesis phase, the centrosome divides into two centrosomes.

The kinetochore, a protein complex that encircles the centromere of the chromosome, is where spindle fibers are connected. They then shorten toward the centrosome during anaphase, pulling the sister chromatids that comprise a chromosome apart from one another. Each new nucleus must include the proper amount of chromosomes in order for this to happen.
