An organism has 18 chromosomes in its body cells. Its sex cells have 9 chromosomes.
Which statement correctly explains this?
Answers
For an organism that has 18 chromosomes in its body cells and its sex cells have 9 chromosomes, the correct statement is C, Its sex cells are haploid and a result of meiosis.
What are haploids?Haploid cells have half the number of chromosomes as diploid cells. Mitosis is a type of cell division that produces two identical daughter cells. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell.
In the organism described, the body cells are diploid (18 chromosomes) and the sex cells are haploid (9 chromosomes). This is because the sex cells are produced by meiosis, which is a type of cell division that reduces the number of chromosomes by half. This allows the sex cells to combine with each other to form a new diploid cell, which is the beginning of a new organism.

a. whale and human or whale and tuna
b. pig and rhesus monkey or pig and chicken
c. tuna and fly or tuna and chicken
Answers
Answer:
a. whale and tuna
b. pig and chicken
c. tuna and fly
Explanation:
Following, you will find characteristics of each species that differ in the contrasting groups. These descriptions reflect the divergence degree between groups.
a. whale and tuna
Whales: Vertebrate and Big-sized marine mammals. They are long-lived and pulmonate animals. They are relatively slow, and only breathe while they are on the surface, opening the blowhole which covers the narines. Despite being mammals, they lack hair, so they have naked soft skin. They have one dorsal fin, two lateral flippers, and a caudal horizontal fin, which they move up and down. They are viviparous, with internal fecundation, and females carry mammal glands to feed their offspring. They feed on krill and other small animals, which they filtrate using their baleens. Whales exhibit the Type I survivorship curve. Mortality often occurs at the end of the cycle. They have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success. They are used to swim deep depth or near the surface depending on the reproductive cycle stage. Tuna: Bony marine fish. Fusiform and medium-sized body, fast swimmers. They can live for 15 years. Their body is covered with scams. They have two dorsal fins, two ventral fins, two lateral fins, and a caudal fin which they move from side to side. It swims near the surface and interchange gas using the grills. They have many teeth and feed on anything they can, such as small fishes, zooplankton, crustaceans, and mollusks. They have external fecundation and exhibit the Type III survivorship curve. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.b. pig and chicken
Pigs: Heary Mammal, with thick hairs, called bristles and mammal glands. They are four-legged, have hooves and four fingers. Their snout is long and flexible, with sharp teeth. They have a curly tail and thick and sensitive skin. Naturally, they are herbivorous but became omnivorous in captivity. They can live for ten or fifteen years. Viviparous. Well-developed smell sense and no sudoriparous glands. Territorial, dominant, and highly communicative with partners. They can use more than twenty different sounds. They also exhibit the Type I survivorship curve.Chickens: Birds. They have two legs and two wings however, it has never been successful in flying. Their body is cover by feathers. They have no hair, and they do not have teeth either, but they have a corneous peak instead. They are omnivorous. They show sexual dimorphism, especially in feathers and crests. They exhibit the type II survivorship curve. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care.c. tuna and fly
Tuna: Already described aboveFly: Flying and small-sized Insects. Dipterous, with their bodies divided into three regions: Head, thorax, and abdomen. They have six appendixes to walk, one pair of wee-developed wings, one pair of vestigial wings, eyes very sensitive to light. The mouthparts are used to lick, suck or bite. Some species can sting and suck blood from humans. Their body is covered with thin hairs and sensory bristles used to taste, feel, and smell. They are attracted by smelly matter, from which they feed on. In general, flies are associated to matter in decomposition and wastes. They have a short life cycle and can live up to twenty-five days. Ovoviviparous species, laying too many eggs that will turn into larvae and finally to the adult fly stage.Based on Model 3, the pairing of organisms that would have the most divergence in their DNA is: A. whale and human or whale and tuna.
What is genetics?Genetics can be defined as the scientific study of genes, chromosomes, heredity and the similarities or divergence (variations) of traits (DNA) in living organisms such as animals, humans, and plants.
Based on morphology and ecology, whales are aquatic and gigantic vertebrate (mammals) that only live in water. Also, whales are pulmonate and carnivorous animals that feed on other animals.
From Model 3, the number of amino acids differences between whale and human is ten (10) while that of whale and tuna is equal to seventeen (17). Therefore, we can deduce that the pairing of organisms that would have the most divergence in their DNA is whale and human or whale and tuna.

. If untreated, how will HIV’s effect on helper T-Cells affect a person’s immune response? Be specific using details from what you have learned.
Answers
If left untreated, HIV can significantly affect a person's immune response in several ways. Firstly, HIV can reduce the number of CD4+ T cells in the body, leading to a weakened immune system. As the virus replicates and destroys more CD4+ T cells, the body becomes increasingly vulnerable to opportunistic infections and cancers.
Secondly, HIV can impair the function of CD4+ T cells that remain in the body. Even if there are enough CD4+ T cells present in the body, they may not function correctly due to HIV's impact on their signaling pathways. This can lead to a weakened immune response and an increased risk of infections.
Answer:
HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.
which measurement is likely the least accurate? Explain.
What observations and/or patterns do you see in the data?
Answers
Based on the information, we can infer that the measurement that could be the least probable is caudal peduncie depth strandard error. Also, the trend is for lake values to be higher than river values.
What difference do we see in the values in the table?To identify the values we must analyze the table and identify they are not the trends. In this case we can infer that the tendency is for the values of the lake to be higher than the values of the river because all the values of the lake are higher than those of the river.
On the other hand, we can infer that the value that could be the least successful is the peduncie depth strandard error because it shows equal values. However, if we take into account the previous values, it should not be the same in both cases.

5. What is symbolic about the Dragon’s Cup and why was it added to the movie?
Answers
Beowulf and Grendel's mother formed an alliance, and the dragon's cup served as a sign of their understanding. It is appropriate for the film, and perhaps alludes to Beowulf and the dragon's conflict.
What is symbolic about the Dragon’s Cup?The dragon's hoard of treasure eloquently symbolizes both, the flimsiness of human desires and the changeability of time. The wealth in the dragon's tomb is plentiful, but no one can use it.
Gardner uses the dragon as a symbol for life's sorrow—the kind of misery that might result in the gloomy beliefs (and disgusting social behaviors) he eventually shares with Grendel.
Beowulf grabs a knife from his belt and stabs the dragon's flank desperately. The fatal strike causes the writhing serpent to wither.
But as soon as Beowulf achieves victory, the cut on his neck starts to enlarge and burn. He understands that the venom from the dragon bite is killing him.
Therefore, flimsiness of human desires and the changeability of time symbolic about the Dragon’s Cup.

Corals glow because they contain tiny algae called zooxanthellae. These algae live inside the coral's tissues and provide the coral with food and oxygen.
How to explain the information
In return, the coral provides the algae with a safe place to live and carbon dioxide. When the water temperature gets too warm, the algae start to die. This causes the coral to lose its food source and turn white, a process called bleaching.
If we don't take action to reduce greenhouse gas emissions, the oceans could be too warm for any corals to survive in as little as 30 years.
About half of the coral reefs on the Great Barrier Reef have died in the past 30 years.

Answers
Answer:
Animals release carbon dioxide when they breathe which plants take in to help make food
Animals release carbon dioxide when they breathe which plants take in to help make food. So the correct option is D.
Why do animals and plants depend on each other?
All species present on earth depend on each other for performing basic life processes. Humans are not able to survive beyond a particular range of temperature and pressure. For all the species to survive, a healthy environment is required.
Plants and animals are dependent on each other. This is because, in ecological systems, no species can survive alone. Animals are dependent on plants. Plants are the primary producers in our ecosystem. They produce food that is consumed by primary consumers and the primary consumers are consumed by secondary consumers.
Plants use carbon dioxide for photosynthesis and it results in the production of oxygen. This is used by animals for the process of respiration.
Plants depend on animals for several reasons. These can be fruit and seed dispersal, pollination, and also for the carbon dioxide that the animals produce. Thus, both plants and animals are interdependent on each other.
Therefore, the correct option is D.

What is sleep stage?Sleep stages are nothing but electrical wave activities in the brain. This wave movement is measured by an electroencephalogram (EEG). There are 2 main stages in our sleep such as REM and NREM.
The NREM is the first stage of the sleep cycle. It has 3 substages - N1, N2, N3 stages. In the N1 stage individuals feel sleepy, hallucinates. It is the light sleep stage and people can awake from this stage of sleep easily.
N2 stage is the next sleeping stage. In this stage, the electrical waves are more and called theta waves. Here, it is hard to awake. Sleep spindles, K - complex are found in this stage, which helps in a deep sleep.
REM or rapid eye movement is a deep sleep stage. It is also called paradoxical sleep. Here, the brain is more active and the body is paralyzed. During this stage a person dreams.
