Answer:
E. juxtaglomerular complex
Explanation:
Macula densa cells are the columnar tubule cells. They are present in the wall of afferent arterioles. The modified fibers of smooth muscles present in the lining of the afferent arteriole are called juxtaglomerular cells.
The juxtaglomerular cells and macula densa cells together make the juxtaglomerular apparatus, also called juxtaglomerular complex. The function of the juxtaglomerular apparatus is to maintain the blood pressure of kidneys.

Explanation: srry if I'm wrong
Of the two pink monkeys in the world – one male, one female – the female dies, ensuring that there will never be a pure-bred pink monkey again.
A random succession of births results in all other hair colors going extinct within a village full of redheaded people.<span>

Organisms,such as hawks and leopards, that obtain their energy from foods they consume are called :
b) heterotrophs
The answer is c. 0.42.<span>
If:
p - the frequency of dominant allele P,
q - the frequency of recessive allele
p,
the frequencies of the genotypes are:
p² - for PP genotype (dominant homozygote without the disease),
<span>2pq - for Pp genotype (heterozygote for disease),
q² - for pp genotype (recessive homozygote with the disease).
It is given:
p = 0.3
2pq = ?
Since p + q = 1 </span></span>⇒ q = 1 - p
q = 1 - 0.3 = 0.7
Knowing p and q, we can calculate <span>the frequency of people heterozygous for this disease (2pq):
2pq = 2 </span>· 0.3 · 0.7 = 0.42
Therefore, <span>the frequency of people heterozygous for this disease is 0.42</span>
