It is the pinna. This is the ear’s part that acts as a funnel to concentrate sounds and guide them into the ear. It is this part’s responsibility to collect sound by acting as a funnel of the ear. It is through the pinna that amplifies the sound and directs the sound to the ear canal. The ear of a human is divided into three parts. The pinna is located and part of the outer ear. Hearing does not take place here but rather this is the part where sound is collected and directed into the the internal passage called auditory canal. From this canal, sound travels or passes to the inner part and that is where the sound is processed.
Reproductive isolation refers to the situation where different species live in the same area, but properties of individuals prevent them from interbreeding. the thing which stop species or groups of organisms reproducing sexually are called isolating mechanisms. hope this helps
Answer:
Due to its high magnification power.
Explanation:
A scientist used a light microscope to view an algal cells because light microscope is able to magnify objects up to about a thousand times. Various cellular organelles, such as nuclei, chloroplasts, and mitochondria etc can also be seen clearly with the help of light microscope so that's why scientist used light microscope to study algal cells.
Answer:
A. The dominant factor, or allele, is for round seeds.
Explanation:
Gregor Mendel discovered the principles that governs inheritance. During his numerous experiments, he conducted a cross in pea plants involving a single character. This cross is called MONOHYBRID CROSS. In one of these monohybrid crosses, he observed the gene for seed shape in pea plants. He discovered that two alleles are responsible for the expression of this gene: round allele (R) and wrinkled allele (r).
He crossed plants that produced only round seeds i.e. homozygous RR and plants that produced only wrinkled seeds, rr. He observed that the F1 offsprings were all round-seeded. This made him to propose his LAW OF DOMINANCE, which states that an allele is capable of masking the expression of another in a gene. He concluded that the round allele is covering the wrinkled allele in a heterozygous state, since it is expressed over it. He then called the round allele, DOMINANT allele and the wrinkled allele, RECESSIVE allele.
