Answer:
Answer is option D.
Flowers contain parts for making seeds.
Explanation:
The part of the plant that is responsible for the sexual reproduction in plants is known as flowers. A flower is said to be complete if contains sepals, petals, stamens and pistil. If the flower lacks one or more structures, it is an incomplete flower.
A complete flower consists of a vegetative part and a reproductive part. The vegetative part contains petals (a bright coloured structure that attracts insects and birds) and sepals (a green coloured structure that protects rising buds and is usually found beneath the petals). The reproductive parts include stamen or androecium (male reproductive organ) and pistil (female reproductive organ). A flower may consists of only female parts or only male parts, or both.
Stamen contains two parts - anther, which produce and store the pollens (male gametes) and filament, which support the anther. Pistil contains three parts - stigma, which receives the pollen grains and style that connects stigma and the ovary, and ovary which contains a lot of ovules (female gametes) which forms the seed.
Flowers reproduce by pollination, a process in which the pollen are transferred to the stigma of another flower. A pollen tube emerges from the pollen grain and grows through the style and reaches an ovule inside the ovary. Then the nucleus of the pollen grain passes through the pollen tube and fuses with the nucleus of the ovule and this process is known as fertilisation. The fertilised ovules become seeds and the ovary transforms into the fruit. The seeds are dispersed through various methods and the embryo inside them will grow into adult plants.
I believe one is Tourettes
Answer:
Salivating at the sight of food is an example of unconditioned response.
Evolution can also influence the acquisition of conditioned/learned response.
Animals learn to avoid eating things that are harmful or cause illness.
Monkeys can more easily be conditioned to fear snakes than to fear koalas.
Explanation:
- <u><em>Unconditioned stimuli</em></u>: Biologically significant stimuli that provoke an unlearned or reflex reaction. For example, food is an unconditioned stimulus.
- <u><em>Conditioned stimuli</em></u>: neutral, inoquos or biologically not significant stimuli.
- <u><em>Unconditioned Responses</em></u>: Unlearned response that is triggered by reflex because of an unconditioned stimulus. An example is salivating.
- <u><em>Conditioned Responses:</em></u> These are provoked by conditioned stimuli. This refers to a learned response that reflects the association between conditioned and unconditioned stimuli.
Initially, an unconditioned stimulus does not provoke any response, but after enough exposition to conditioned and unconditioned stimuli together, the simple presence of unconditioned stimuli induces conditioned responses. In this aspect, the subject has learned to predict or to anticipate the unconditioned stimulus.
Animals also learn to avoid tastes that might cause them illness or might be harmful to them, and so they also learn to ignore visual or auditory sings that help them predict illness.
The detection of a harmful stimulus is an evolved predisposition rather than learned. Monkeys can show a detection advantage for a harmful animal such as the snake among non-harmful animals such as koalas. Indeed, snakes are an evolutionary threat stimuli in primates because most of them are poisonous.
Global warming is the gradual increase of earths atmospheric temperature caused by increase emission of carbon dioxide and other pollutants.
