Animal-mediated pollination ... (choose one most appropriate answer)
O Is characteristic of the 4th great radiation of the land plants, which resulted in a group of plants called the
Angiosperms.
O Tends to increase inbreeding among the species of plant being pollinated.
O Likely has decreased the diversification of both insects and flowering plants.
O Allows the plant to reproduce only when the plant population is at a high density.
O Is a less efficient mode of pollination than wind pollination.
Answers
Answer: Tends to increase inbreeding among the species of plant being pollinated.
Explanation:
Animal-mediated pollination, where animals such as insects, birds, or bats transfer pollen from one flower to another, tends to increase inbreeding among the species of plant being pollinated. This is because animals often visit multiple flowers of the same plant or closely related plants in close proximity, leading to a higher likelihood of pollen being transferred between closely related individuals. This can result in reduced genetic diversity and increased inbreeding among the plant population, which may have both positive and negative effects depending on the specific species and ecological context.
The other options provided do not accurately reflect the characteristics of animal-mediated pollination. For example, animal-mediated pollination is actually considered to be a more efficient mode of pollination compared to wind pollination, as it allows for targeted and controlled transfer of pollen between flowers, increasing the chances of successful pollination and reproduction. Animal-mediated pollination is also not limited to high plant population density or specific plant groups such as angiosperms, and there is no evidence to suggest that it has decreased diversification among insects and flowering plants.

what are genes made of
Answers
Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
The Mendelian components of heredity, however, weren't initially referred to as genes until Wilhelm Johannsen made the suggestion. The suggested term has its roots in the Greek word genes, which means "birth." Others, like genome, were born from the word. The body contains protein in practically every organ, tissue, and bodily component, including muscle, bone, skin, and hair. Both the hemoglobin, which carries oxygen in your blood, and the enzymes that drive several chemical processes are made of it. You are made up of at least 10,000 distinct protein that both build and maintain who you are.

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.

Answer:
The correct answer is - people accept it in exchange for goods and services.
Explanation:
Money is valuable because we know that it is "accepted." Money can be used to purchase goods and services even though it is no longer backed by gold. Security measures prevent counterfeiting but do not add value.
People know at that time that their current money has value when they accept it in exchange for goods or services, which is option C, as money is a medium of exchange.
The value of money is influenced by central banks. Different countries have different currencies, but the currency that is stable and has more security has more use. Money is also linked to the underlying economics, such as the ability of a country to buy and manufacture goods, thus increasing the economy. There are also many security measures, such as unique designs, special inks, holograms, etc., that are helpful for maintaining trust and confidence in the currency.
