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.

Which of the following areas would be the best location to store chemicals? • In a locked closet with ventilation • In the pool closet O Under the sink in the kitchen • On the ground in the garage
Answers
Answer:
A
Explanation:
I'm assuming you're talking about dry chemicals. An example of where dry chemicals should be stored is yeast, which should be treated in a similar method. In a locked closet, there wouldn't be a lot of external effects and with ventilation, the chemicals would maintain their structure. In a pool closet, obviously, there would be a lot of moisture, so this could cause some explosive reactions to some of the chemicals. The sink in the kitchen has the same properties as in a pool closet. Finally on the ground in the garage wouldn't be a good place to store chemicals as it is cold and has little to no ventilation.

what important things do primary producers such as phytoplankton and giant kelp provide for a healthy ecosystem?
Answers
Answer:
Phytoplankton are the foundation of the ocean food web, providing organic matter for virtually all other marine creatures. Their primary productivity limits the growth of crustaceans, fish, sharks, porpoises and other marine creatures. They are responsible for half of the photosynthetic activity on the planet. Phytoplankton’s role in the global ecosystem has made them a target for controlling carbon-dioxide levels in the earth’s atmosphere.
Giant kelp is a type of brown algae that grows in shallow, nutrient-rich saltwater near coastal fronts around the world. It provides habitat and food for a variety of marine organisms. Kelp and other types of marine vegetation absorb an estimated 20 times more carbon dioxide per acre than forests on land, making it a powerful force in storing this persistent greenhouse gas and mitigating the effects of climate change.

Sharks have a disproportionate effect on coral species diversity by keeping weedy algae in check. Sharks are therefore this type of species, which when removed, can lead to dramatic decreases in species diversity. (true or false)
Answers
Sharks are considered a keystone species because they play a critical role in maintaining the balance of the ecosystem they inhabit.
In this case, they keep weedy algae in check by preying on herbivorous fishes that feed on algae-eating organisms. If sharks were to be removed from the ecosystem, the herbivorous fishes would increase in number and consume more algae-eating organisms, which would then allow the weedy algae to grow and outcompete the coral for space, sunlight, and nutrients. As a result, the coral species diversity would decrease, and the ecosystem would become less healthy and productive.
Keystone species are those species that have a disproportionate effect on their ecosystem relative to their abundance. Their removal can cause significant changes to the structure and function of the ecosystem. Some other examples of keystone species include sea otters, beavers, and wolves.

Answers
Natural selection does not produce the mutations that are in option A, as natural selection is the process by which certain advantageous traits become more common in a population over time because individuals with those traits are more likely to survive and reproduce.
Natural selection does not produce the mutations themselves. Mutations are random changes that occur in an organism's DNA and can happen for various reasons, such as exposure to radiation or mistakes during DNA replication. Natural selection acts on the variation already present in a population, selecting for traits that confer advantages in a given environment and allowing those traits to become more prevalent over time.

During alcoholic fermentation, when is NAD+ converted to NADH -- during the conversion of glucose to pyruvate (glycolysis) or during the conversion of pyruvate to alcohol?
Answers
Answer:
During the conversion of glucose to pyruvate glycolysis or during the conversion of pyruvate to alcohol
Explanation:
During the conversion of glucose to pyruvate, NAD+ is converted into NADH.
What is alcoholic fermentation?Alcoholic fermentation is a biological process that converts sugars into cellular energy while emitting ethanol and carbon dioxide as byproducts.
The NADH + H+ from glycolysis would be recycled back to NAD+ during the fermentation process, allowing glycolysis to continue. NAD+ is reduced during glycolysis to form NADH + H+.
Thus, during this, when glucose is converted to pyruvate, NAD+ is being converted to NADH.

SECTION B: QUESTION 2 2.1 The diagram below shows part of the human ear. 2.1.1 2.1.2 2.1.3 2.1.4 E A B C Explain the consequence if structure E lost its flexibility. Describe the process of hearing. D 2.Z Identify structures A and B Give the LETTER and the NAME of the parts that: (a) equalises pressure on both sides of the tympanic membrane (b) absorbs excess pressure waves from the inner ear (2) (2) (2) (2) (7) (15)
Answers
If structure E (stapes) lost flexibility, it would impair sound transmission, leading to hearing sensitivity.
Process of hearing: Sound waves enter the ear, vibrate the eardrum (tympanic membrane). Ossicles (A: malleus, B: incus) amplify vibrations to inner ear. Vibration of fluid in cochlea stimulates hair cells, converting to electrical signals for interpretation.
Structure A: Malleus
Structure B: Incus
(a) Structure C (eustachian tube) equalizes pressure on both sides of the tympanic membrane.
(b) Structure D (round window) absorbs excess pressure waves from the inner ear.
If structure E, which is the ossicles (specifically the malleus, incus, and stapes), lost its flexibility, it would have a significant consequence on hearing. The ossicles play a crucial role in the process of sound transmission. They amplify sound vibrations that enter the ear through the outer ear and transfer them to the inner ear. The flexibility of the ossicles allows them to vibrate in response to sound waves, transmitting these vibrations to the fluid-filled cochlea in the inner ear.If structure E lost its flexibility, the transmission of sound vibrations would be impaired. This would result in a reduced ability to perceive and interpret sound. Hearing sensitivity would be significantly compromised, and sounds may appear muffled or distorted. It may become challenging to distinguish different pitches or understand speech clearly.The process of hearing involves several steps. When sound waves enter the outer ear, they travel through the ear canal and reach the eardrum (tympanic membrane). The vibrations of the eardrum are then transferred to the ossicles (structures A and B in the diagram), which amplify and transmit the vibrations to the cochlea (structure C). The cochlea is responsible for converting the mechanical vibrations into electrical signals that can be interpreted by the brain. These signals are then sent to the brain via the auditory nerve, where they are processed and perceived as sound.Structure A, known as the Eustachian tube, equalizes pressure on both sides of the tympanic membrane. It connects the middle ear to the back of the throat, allowing air to flow in and out, maintaining equal pressure on both sides of the eardrum.Structure B, called the round window, acts as a pressure relief valve. It absorbs excess pressure waves from the inner ear, preventing damage to delicate structures by allowing fluid in the cochlea to move in response to the sound vibrations.Overall, the ear is a complex and intricate system that relies on the interaction of various structures to enable the sense of hearing.For more such questions on Hearing sensitivity:

Hearing involves a process of sound wave transduction through the tympanic membrane and ossicles. If the tympanic membrane (E) loses its flexibility, sound quality may diminish. The Eustachian tube and cochlea serve to manage pressure within the ear.
Explanation:The process of hearing (audition) involves the transduction of sound waves into a neural signal. When the tympanic membrane (structure E in your diagram), or eardrum, is struck by sound waves, it vibrates. These vibrations are then transferred to the ossicles, which are three small bones in the middle ear. The ossicles are identified as structures A (Malleus or Hammer) and B (Incus or Anvil) in your diagram. Sound waves are finally transduced into a neural signal in the inner ear.
If the tympanic membrane was to lose its flexibility, it would not vibrate as effectively when struck by sound waves. This could diminish the quality of sound and potentially lead to hearing loss.
The Eustachian tube equilibrates air pressure on both sides of the tympanic membrane. This would be your answer to part (a) of the lettered question. Part (b) refers to the role of the cochlea in the inner ear, which helps to absorb excess pressure waves from the inner ear.

Did the amount of water that condensed at the top of the terrarium change as plants sprouted and grew? described what you observed, using data from your experiment. why do you think this happened ?
Answers
The amount of water that condensed at the top of the terrarium change as plants sprouted and grew because water, oxygen and nutrients are very essential elements for growth.
The plant cells grow in size by cell enlargement which in turn requires water. Turgidity of cells helps in extension growth. Thus, plant growth and further development is intimately linked to the water status of the plant. Water also provides the medium for enzymatic activities needed for growth. Oxygen helps in releasing metabolic energy essential for growth activities. Nutrients (macro and micro essential elements) are required by plants for the synthesis of protoplasm and act as source of energy.
Thus as plant grows it needs more water to provide to it's larger plant body and which causes decrease in the amount of water that condensed at the top of the terrarium.
