Answer:
<h2>In all flies,on the same Locus, on chromosome 2 at the same place you find the gene for antenna length.</h2>
Explanation:
In all fruit flies ,on the same Locus, on chromosome 2 at the same place you find the gene for antenna length
All fruit flies contain same amount of gene and chromosomes, so the location of all gene in all fruit flies found at the same location.
A gene for antenna length in all fruit flies on chromosome 2 is present on same the location.
Answer:
c. Left atrium
j. right atrium
f. left ventricle
g. right ventricle
Explanation:
The heart consists of four chambers that is two ventricles and two articles.
Blood enters the right atrium goes into the right ventricle.
The right ventricle then pumps blood into the lungs where the blood gets oxygenated.
Pulmonary vein then brings back the blood from lungs into the left ventricle, blood is pumped into the left atrium and out of the heart.
That is the process through which blood navigates in the heart.
Answer:
A. supplementary motor cortex; premotor cortex
Explanation:
The supplementary motor cortex, also known as the supplementary motor area (SMA), is an area of the cerebral cortex located anterior to the premotor cortex. This area (SMA) is involved in the execution of complex and rapid sequential movements (e.g., typing). Moreover, the premotor cortex is an area of the motor cortex located between the primary motor cortex and the prefrontal cortex. This area (premotor cortex) is activated during motor tasks including, among others, spatial and sensory guidance of movement.
Answer:
The first blank can be correctly filled up with proteins.
Proteins are complex molecules which play many crucial roles in the body such as structural role (actin, myosin, keratin), movement, metabolism (enzymes), signal transduction, transport, and defense. In addition, they also determine many traits of the body as they are the last result of the gene expression.
The second and third blanks can be correctly filled up by DNA (deoxyribose sugar).
DNA is the genetic material in most of the organisms including humans. It contains all the information or blueprint for the synthesis of proteins which in turn help in determining the traits of a person.
The last blank can be filled up by the gene.
A gene refers to the unit of heredity which is present on the chromosome. It refers to the protein coding region of the DNA.
