Answer:

Mitochondria and chloroplasts

Explanation:

These two organelles support the theory in that both have 70S ribosomes, the presence of a circular DNA within, and similar size. They can undergo division within the eukaryotic cyptoplasm. Both of these organelles are surrounded by a double membrane, which in the case of chloroplast is known to originate from ancient bacteria that lost its peptidoglycan component. Mitochondria and chloroplast both evolved from ancient free living bacteria that entered into larger cells, which in the case of mitochondria is known to be archaea and in the case of chloroplast is a eukaryotic cell. With this, these cells became dependent on it in a manner that it could not exist without it.

In humans, MN blood types are determined by an autosomal gene with two alleles: LM and LN. In one population of 592 people, ther
RoseWind [281]

Answer:

148

Explanation:

According to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1 where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q² = frequency of homozygous recessive genotype

Here,

Total population = 592

Number of NN people = 148

Frequency of N blood group or NN genotype (q²) = 148/592 = 0.25

q = √0.25 = 0.5

p = 1 - q

= 1 - 0.5 = 0.5

Hence, p = 0.5

Frequency of MM genotype = p² = 0.25

Number of people with MM genotype = 0.25*592 = 148

Hence, 148 people will have MM genotype or M blood group.

goblinko [34]

Answer:

You drove through Iowa in the spring and noticed that along a stretch of several kilometers, every third fence post had a male red-winged blackbird perched on it defending its nesting territory. This is an example of <u>uniform dispersion.</u>

Explanation:

There are usually three dispersion patterns :

  1. Clumping
  2. Uniform dispersion
  3. Random dispersion

Clumping is the most common.

Uniform dispersion occurs when

  • resources are scarce
  • Individuals are evenly spaced in a habitat
  • Due to competition or territorial behavior

While Random dispersion occurs when resources are plentiful.

Hence ,This is an example of <u>uniform dispersion.</u>
