Answer:
Petals d. serve to attract animals to collect and disperse pollen.
Explanation:
Petals serve to attract animals to collect and disperse pollen. This is because petals are modified leaves that surround the reproductive parts of flowers protecting them. They have super bright colors and different shapes so they attract pollinators and animals. Petals have different functions depending the type of plant repelling or attracting specific pollinators.
Answer:
This binding causes a conformational change in the receptor which enters into the nucleus and binds DNA to activate transcription
Explanation:
Testosterone is a steroid hormone responsible for inducing protein synthesis and growth of tissues with androgen receptors. Testosterone receptors, also known as androgen receptors, are a class of nuclear receptors activated by binding androgenic hormones (e.g. testosterone) in the cytoplasm, whose binding induces a conformational change of the receptors that are subsequently translocated to the nucleus. Within the cell nucleus, these activated receptors form homodimers that bind DNA in order to promote the transcription of target genes capable of regulating cell growth, cell cycle progression and survival.
Petals: The main function of petals is to attract pollinators
Anther: It produces and contains pollen, the male sperm in plants.
Filament: it's the sterile part of the male reproductive organ, and its main function is to sustain the anther.
Pollen: it's the grain that is produced by plants that have flowers (angiosperms), it's the male germinate cell, analogous to spermatozoon in animals.
All these organs are part of the reproductive system in plants, and are not present in animals. But we can make analogies to some of these structures with the animal reproductive system as we did with pollen and spermatozoon
Answer:
Messenger RNA is a single-stranded RNA molecule that corresponds to the genetic sequence of a gene and is read by the ribosome in the process of producing a protein.
Explanation:
The deer population decreased drastically because there were so many hostile animals where the deer where. For instance the wolves went up, then down as the deer decreased. When the wolves were low, the deer increased in growth.
