Many plants depend on animals primarily insects for pollination and sexual reproduction. If the animals (insects that pollinate) most flowering plants would be unable to reproduce and would go extinct.

Both plants and animals undergo cellular respiration producing Carbon Dioxide. Animals produce only Carbon Dioxide while plants produce both Carbon Dioxide and Oxygen. If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide.

Plants that survived the extinction of animals would be much simpler than presently complex plants.

Perhaps some plants would become predators of other plants to absorb the nitrogen content of other plants because of the lack of animals to engage in the recycling of nitrogen content.

A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotyp
lana [24]

Answer:

Frequency of allele A1- 0.41

Explanation:

In Hardy weinberg equilibrium,

P refers to the dominant allele

q refers to the recessive allele

The allele frequency will be p+q=1

The genotypic frequency is- P²+q²+2pq=1

P²= genotype of dominant trait ( A1A1)- 77

2pq= genotype of heterozygotes (2pq)- 65

q²= genotype of recessive trait (A2A2)-  123

Total number of offsprings= 77+  65+ 123

                                            = 265

Now to calculate allele frequency of A1=

\dfrac{\text{number of A1A1 offspring}}{ \text{total number of offspring}}+\dfrac{1}{2}(\dfrac{\text{number of A1A2 offspring}}{\text{total number of offspring}})

= 77/265 + 1/2( 65//265)

=  0.290+ 0.122

= 0.413

Thus, 0.41 is correct.

A student is preparing a solution of 0.1 M Tris-Cl (pH 7.0) with 200 mM NaCl. To adjust the pH, the student started with concent
Sophie [7]

Answer:

The correct statements are C The pH is accurate but the solution will have excess salt. D The pH is accurate but the concentration of Tris will be incorrect

Explanation:

As the pH is finally maintained at 7 the pH for the buffer solution will be accurate but excess salt will be produced due to use of Both NaOH and HCl to make up the to 7.

As more volume of water is required at final step to make up the volume the concentration of tris will be incorrect.

Dima020 [189]

Answer:

Cooperation

Explanation:

Cooperation is a type of behavior evolved by members a species living together in a close-knit society, whereby they all work and act together to ensure the common good of all members. This behavior ensures the survival of the members of the species in any environment.  

Cooperation among small birds ensures protection of the members of the group against predators. Also, pack hunting is a form of cooperation among animals of a species to ensure nutrition is provided for all in the group. Se animals also form defensive circles as a form of cooperation to ensure protection of members, especially the weak and young members, against predators.
