Answer:
red
Explanation:
When the source of light moves away or comes closer to an individual, the wavelength of the light decreases or increases respectively and the color of the light changes slightly in what is known as the <u>doppler effect</u>.
When the light source moves towards an individual, the wavelength shifts towards the <u>blue</u> end of the spectrum, and the phenomenon is known as the <u>blueshift</u>. When the source of light moves away from an individual, the wavelength shifts towards the <u>red region</u> of the spectrum, and the phenomenon is known as the <u>redshift</u>.
Answer:
B or Letter B
Explanation:
Ovules are found in the ovary. The ovary can be described as the oval structure at the base of the flower.
The flower is found in the Angiosperms, that is, the flowering plants. And it is known to be the part of the plant that allow sexual reproduction to occur. The flower usually contains the reproductive parts, which include
* Androecium... This is known to be the male reproductive part of a flower, and it comprises the Anthar { this encloses the pollen grains}, and the filament.
* Gymnoecium... This is the female part of the flower and comprises of the stima, style and the ovary { encloses the ovules}.
In conclusion, the pollen grains will fuse with the ovules,[ this is known as fertilization], to form a fruit. The pollen grains can be compared to the spermatozoa in Man, while the ovules are like eggs in the woman.
A hormone imbalance may occur if this feedback system has trouble keeping the right level of hormones in the bloodstream, or if your body doesn't clear them out of the bloodstream properly.
Answer: Antigens
Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).
Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.
