<span>Sunlight emits light energy which is absorbed by the thylacoids in the chloroplasts of a plant. Chloroplasts are organelles in a plant cell whose funtion is photosynthesis (the use of light to make energy). Thylacoids are a part of the chloroplast which absorbs light. The thylaciods convert the light into energy molecules NADPH and ATD. The Calvin cycle then takes place in the stroma (gellatinous matrix of the chloroplast). The Calvin cycle is the use of ATP and NADPH plus carbondioxide to produce starch. Starch is the polysaccharide sugar formed from glucose synthesized in a linear chain. The starch is the storage of the glucose which is used as an energy source for the plant cells. </span>

A locus that affects susceptibility to a degenerative brain disease has two alleles, V and v. In a population, 16 people have ge
Pie

Answer:

Yes, the population is evolving

Explanation:

Hardy-Weinberg equilibrium states that a population is not evolving if it is in hardy weinberg equilibrium as the alleles frequency do not change over time in generations.

In mathematical equation, the genotype frequency will be -P²+2Pq+q²=1 and allele frequency will be p+q=1, where p = dominant allele and q will be recessive allele.

In the question, since the observed genotype are-

P² - VV= 16

2Pq- Vv- 92

q²- vv- 12

<u>1. Calculate allele frequency</u>

Now we will calculate if the expected value is same or close or not.

We will calculate allele frequency

Population has 120 individuals which means it has - 240 alleles.

In which V (p) will be- 32 +92= 124 allele

p- dominant allele/ total allele=  124/ 240 = 0.52

P= 0.52

q will be 1-0.52= 0.48

<u>2. Expected genotype frequency</u>

Now we will calculate expected genotypic frequency.

P²- 0.52 X 0.52= 0.27

2Pq = 2 x 0.52x 0.48 =  0.5

q²= 0.48 x 0.48 =  0.23

<u>3. Expected progeny </u>

P²= 0.27 x 120= 32 VV

2Pq= 0.5 X 120= 60 Vv

q²= 0.23 x 120= 28 vv

Since the observed value is not equal to the expected value therefore the population is not in Hardy- Weinberg equilibrium and the population is evolving.

Thus, Yes, the population is evolving is correct.

Compare transitional aqautic ecosystems. Identify two types and describe the environments each type combines
Dennis_Churaev [7]

A transitional aquatic ecosystem is one type among the aquatic systems.

There are two types in it.

  • Estuaries
  • wetlands

Explanation:

  • Estuary is formed when freshwater from the river combines with salt water from the ocean.
  • The estuary is a  home for a variety of species.
  • Algae and marsh grasses are dominant producers.
  • Wetlands are saturated with water and support aquatic plants for their survival.
  • It serves as a living place for a variety of species ranging from reptiles, birds to some mammals

dangina [55]

Answer:

Loss of cell wall integrity or

Explanation:

Grams staining i a staining method used to classify bacteria into two main classes. Gram positive and Gram negative.

They are differentiated according to the ability of their cell wall to retain the primary stain color of the crystal violet stain or the counter stain pink.

Bacillus subtilis is a Gram positive bacteria hence it is supposed to stain purple.

Therefore, when it stained pink is an error. it shows loss of the cell wall integrity due to old age, overdecolorization or over fixing with heat.
