What does the allele frequency have to total in the hardy- Weinberg equilibrium?

Answers

Answer 1
Answer: In addition, the sum of the allele frequencies for all the alleles at the locus must be 1, so p + q = 1. ... In population genetics studies, the Hardy-Weinberg equation can be used to measure whether the observed genotype frequencies in a population differ from the frequencies predicted by the equation.

Hope this helps
Answer 2
Answer:

Answer:

1. directional selection

2. Hardy-Weinberg equilibrium

3. sympatric

4. This is allopatric speciation.

5. This is an example of stabilizing selection in a population because the organisms in the middle of the population have the best fitness for their environment.

6. The five conditions impacting this equilibrium are: mutations, nonrandom mating, genetic drift, migration, and natural selection.

7. Natural selection impacts single-gene traits because of the possible extinction of one trait or increase of another trait. If a trait is found to be not preferable in that environment, it could be eliminated through natural selection.

8. The total allele frequency in the Hardy-Weinberg equilibrium has to equal 1.:

How do flowering plants reproduce by fertilization if they are immotile?Fertilization takes place in their roots.
O They conjugate with plants nearest them.
Insects and other organisms carry pollen to other flowers.

Answers

Immotile flowering plants  accomplish fertilization with the help of Insects and other pollen from organisms that carry pollen to other flowers.

Explanation:

  • The transfer of pollen from anther to the stigma of flower is called pollination.
  • Pollination is of two types: a) Self pollination    b) cross-pollination
  • Transfer of  pollen from anther to the stigma of same flower or flower of same plant is called self pollination.
  • Transfer of pollen from anther to the stigma of different plant is called Cross-pollination.
  • Pollination is the process by which angiosperms carry out sexual reproduction.
  • Since, plants are immobile they need some agents for pollination  like, insects birds, wind, water etc

Why is DNA frequently found associated with protein inside cells

Answers

During DNA replication, mRNA copies the DNA in the nucleus and rRNA goes to the ribosome where proteins are made. tRNA matches up to the rRNA and creates polymers. This is called protein synthesis

What is sustainability? How does the concept of sustainability relate to green energy?

Answers

Sustainable energy is energy that is consumed at insignificant rates compared to its supply and with manageable collateral effects, especially environmental effects. Another common definition of sustainable energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their needs. The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture. Sustainability science is the study of sustainable development and environmental science.
Conceptually, one can define three generations of renewables technologies, reaching back more than 100 years .
First-generation technologies emerged from the industrial revolution at the end of the 19th century and include hydropower, biomass combustion and geothermal power and heat. Some of these technologies are still in widespread use.
Second-generation technologies include solar heating and cooling, wind power, modern forms of bioenergy and solar photovoltaics. These are now entering markets as a result of research, development and demonstration (RD&D) investments since the 1980s. The initial investment was prompted by energy security concerns linked to the oil crises (1973 and 1979) of the 1970s but the continuing appeal of these renewables is due, at least in part, to environmental benefits. Many of the technologies reflect significant advancements in materials.
Third-generation technologies are still under development and include advanced biomass gasification, biorefinery technologies, concentrating solar thermal power, hot dry rock geothermal energy and ocean energy. Advances in nanotechnology may also play a major role.

The cell membraneprovides storage in the cell
acts as a barrier
provides energy for all of the internal organelles
resides within the nucleus

Answers

cell membrane is like your skin in a way, it holds the cel together and determines what goes in an out

technically, it could provide storage since it stores the contents of the cell, but this would be the vacuoles

acts as a barrier: this wold be the answer

provides energy: this is mitocondria's job

resides within te nucleous: this is the outside, it's like saying that your skin is all inside your brain



best answer would be acts as a barrier
The cell membrane acts as a barrier because it blocks any "invaders" from coming into the cell, the same way our skin protects any "invaders" from harming our organs inside our body.
I hope I helped! :-)

The process of deposition would make a river change in which way? A.
dirtier water

B.
straighter

C.
wider

D.
more curves

Answers

Answer;

D.more curves

Explanation;

-Deposition is the process of the eroded material being dropped that takes place when a river loses energy. The loss of the river energy is attributed by factors such as reduction in rainfall, increase in evaporation, friction close to river banks and shallow areas which leads to the speed of the river reducing and thus the energy reduces. Deposition process would make a river change in more curves.

Option D. deposition has a process that changes the course of the river, and has curves and acts dragging particles from the soil to the river, in the form of layers and strata and in the process makes a change through the path of the curves
