Answer:
Because each duplicated chromosome consists of two identical sister chromatids joined at a point called the centromere, these structures now appear as X-shaped bodies when viewed under a microscope. Several DNA binding proteins catalyze the condensation process, including cohesin and condensin.
Explanation:
The man with blood type A might have one of two genotypes:
1. Iᵃ Iᵃ<span>
2. </span>Iᵃ i
In this case, Iᵃ is an allele for A group, and i is an allele for 0 group.
The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles (Iᵃ Iᵇ and i)
Answer:
fast- flowing areas usually contain more oxygen than slow-flowing ones.
Explanation:
looking at the statement that accurately compares fast-flowing and slow-flowing areas of stream and water, we need to understand how they flow. a stream flow downhill and it can also flow in a perfect channel, except when flooding occurs and water overflows its channel and spread out across the area of the land. so, fast-flowing generally have higher levels of dissolved oxygen more than slow-flowing because slow-flowing are aerated.
Answer:
Biology can simply be described as the study of living organisms. Biology is divided into many sub categories depending on the features of life that we want to study. For example, molecular biology is the study of molecules which make up living organisms.
Zoology can be described as a branch of biology under which animals are studied. The field of zoology involved studying the taxonomy of animals, their evolutionary histories, physiology, embryology etc. All these studies are parts of biology hence zoology and biology are related.
Apart from these other unifying principles shared between zoology and biology are genetics, cell biology, population biology,biochemistry etc.
<span>Human sweat is a result of our body getting over heated. We sweat through our pores so our temperatures don't go up and as a result we stay at a normal temperature. We may feel hot but that's because we are hot from the heat of something. If we didn't sweat then our temperature would become very high and we would die.</span>
