Which trophies level contains the most energy?
AleksAgata [21]

Answer:

producers

Explanation:

All the energy comes from the sun. a small amount of sunlight energy is trapped by green plants and used in photosynthesis to form organic materials in plants that are sources of food to the rest of the animals. Animals get  this energy when they feed on plants directly like the herbivores or indirectly like the carnivores.

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.

What are the similarities and differences between photosynthesis and cellular respiration?

Recovering from an attack is no easy task.

Monica Lopez

Answered September 19, 2016

How is photosynthesis similar to cellular respiration? How do they differ?

Similarities Between Photosynthesis And Cellular Respiration

Similarities ...

→ Both involve in production of energy

→ Both involve the exchange of gases

→ Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in Chloroplast where as respiration takes place in mitochondria.

→ At critical condition both have alternate pathway.

Differences...

→Photosynthesis takes place in chloroplast, where as respiration takes place in mitochondria.

→Photosynthesis involve production of carbohydrate and respiration involve breaking of carbohydrate.

→ Photosynthesis occur only during presence of sunlight where as respiration occurs all the time.

→ In photosynthesis process Oxygen is released where as in respiration Oxygen is utilised.

These are the main differences between Photosynthesis and respiration.
