Given,
H = brown hair
h = red hair
Mother: Hh (heterozygous It’s given)
Father: hh (homozygous, given)
What is homogeneous and heterogeneous?Homozygous means alike allele whereas heterozygous means unalike or distinct from one another.
So, in the punnet square below, it is shown that there is a 50/50 chance for the offspring to have red hair.
Ratio is 1:1.
But there is also another probability for the offspring to be like their mother, have the dominant gene of black hair overruling the recessive gene of red hair.

what is dendritic cells and difference between dendritic cells and glial cell
Answer:
here--->
Explanation:
Dendritic cells (DC) are the professional antigen-presenting cells of the immune system. In their quiescent and mature form, the presentation of self-antigens by DC leads to tolerance; whereas, antigen presentation by mature DC, after stimulation by pathogen-associated molecular patterns, leads to the onset of antigen-specific immunity. DC has been found in many of the major organs in mammals (e.g. skin, heart, lungs, intestines, and spleen), while the brain has long been considered devoid of DC in the absence of neuroinflammation. Consequently, microglia, the resident immune cell of the brain, has been charged with many functional attributes commonly ascribed to DC.

What are genes?
A. alleles that show the expression of one gene from
another
B. the specific sequences of DNA in an organism
C. small subtle changes in a person
D. dominant alleles that are expressed
Answer:
I believe it is b
Explanation:
I may be incorrect but genetics and natural selection are my passion so I believe this is correct. The way genes work is you receive half of your father's genes and half of your mothers. Whichever genes are dominant end up showing up on your body, which is called a phenotype. DNA is what makes up genes and makes them able to affect you. Let me know if I'm incorrect.

27. || The vocal tract. Many opera singers (and some pop singers) have BIO a range of about 2 \frac{1}{2} octaves or even greater. Suppose a soprano's range extends from A below middle C (frequency 220 Hz) up to E-flat above high C (frequency 1244 Hz ). Although the vocal tract is quite complicated, we can model it as a resoNting air column, like an organ pipe, that is open at the top and closed at the bottom. The column extends from the mouth down to the diaphragm in the chest cavity, and we can also assume that the lowest note is the fundamental. How long is this column of air if v=354 m/s ? Does your result seem reasoNble on the basis of observations of your own body?
This is measures by open harmonics frequency.
f= n*V/(4*1)
What is frequency?
Frequency refers to the number of waves that pass a fixed point in unit time. Frequency is denoted by the symbol f, and is measured in hertz (Hz).
Given,
f=220
velocity= 354 m/s
=> 220 = (nl)*(354)/(4*1)
=>1244 = (n2)*(354)/(4*1)
=> n2/n1= 5.65
=> n1=1, n2=6
=> = 40 cm (final answer).

Jet streams shift the direction of ocean currents, allowing them to affect weather on the continent and influence the pattern of storms.
What is jet stream?Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere.
These bands of strong wind can cause a change in the direction of the ocean currents, there by affecting the climatic condition of a particular geographical location.
Thus, Jet streams shift the direction of ocean currents, allowing them to affect weather on the continent and influence the pattern of storms.
