Answer:
population is number of inhabitants in area or place
Answer:
The correct answer is option B, The gametophytes grow directly from the sporophyte
Explanation:
Conifers are gymnosperm which reproduce through the exposed seeds (seeds not included in fruits) found in the cones. The trees or plant on which these conifers grow are called sporophytes. In the sporophyte, the male and female gametes fuse together to form zygote which further develops into a seed. At the right time, these seeds get dispersed into wind and they grow into new plants known as sporophytes.
Answer:
d. ATP is present and the intracellular Ca2+Ca2+ concentration is high.
Explanation:
Myosins are motor proteins that plays a major role in muscle contraction. They depend on ATP and responsible for motility in actin-based substances. Skeletal muscle is composed of myosin and actin fibers. Each myosin thick filament is surrounded by actin thin filaments, and each thin filament is surrounded by thick filaments. There exists a strong attraction between the myosin head and the myosin-binding site of actin which binds them spontaneously. This bond is aided by the presence of ATP and the high concentration of intracellular Ca2+. The myosin protein undergoes a change in its shape.
Answer:
nucleus.
The DNA unzips.
A strand of RNA is made.
The RNA moves to the cytoplasm.
A protein is produced.
The RNA leaves the ribosome.
Explanation:
The central dogma of molecular biology is an explanation of the flow of genetic information from DNA to protein within a biological system. It starts from replication in which DNA strands are duplicated. It goes toward transcription in which RNA strand is made from DNA in transcription. This mRNA moves toward the cytoplasm, outside the nucleus. T-RNA goes toward the ribosome and binds there to make protein from translation. After protein production, this rRNA leaves the ribosome.
