According to Mendel's Law of Segregation, meiosis involves the separation of a parent organism's alleles in order to form gamete

s. Since the alleles separate into different gametes, only one allele passes from each parent on to an offspring. This segregation of alleles during meiosis
A)decreases the genetic variability of the offspring.

B)increases the genetic variability of the offspring.

C)decreases the chance that an offspring will receive a dominant allele.

D)increases the chance that an offspring will receive a dominant allele.

Five ounces of beef strip steak would count as ____ ounce equivalent of the protein foods.
Andrews [41]

The 5 ounces of beef strip steak would count as 5-ounce equivalents in the Protein Foods Group.  

Al the foods made from poultry, meat, seafood, peas and beans, eggs, processed soy products, seeds, and nuts are regarded as the component of the Protein Foods Group.  

Steak, like any other animal product, is a rich source of protein. A 5 oz serving of steak gives 38 grams of protein, more than 6 times of the amount in one egg. The proteins help in repairing muscles and other tissues and also helps in building muscles.

Which is a correct interpretation of the cladogram shown below?
nataly862011 [7]

A cladogram is an image or a diagram that shows us an evolutionary relationship between different organisms. Up at the top we find the different organisms and their names. Along the side is where we find their characteristics. Anything that is past each characteristic will have that characteristic as you move up the cladogram. This diagram also shows which organisms are most closely related to one another.



Please see the image for an example. In this example we can see that the Koalas evolved after the trout.



I hope this helps, Regards.

Need help with this evolution chart some I've filled in yet I'm not sure if they are correct.Plz help anybody
Svetllana [295]

Answer:

This is correct. The remaining portion:

Sympatric species that form interrelationships undergo coevolution.

Allopatric species in different environments can undergo convergent evolution.

Allopatric species in small populations and under intense environmental conditions can undergo genetic drift.

Explanation:

On the basis of geographical distance, speciation is of two major types:

  1. Sympatric
  2. Allopatric

Sympatric Speciation:

Sympatric speciation is the formation of new species with no gergraphical separation from the ancestor. The new and parent species both exist in the same environment but do not interbreed due to mechanisms of reproductive isolation. These involves both prezygotic and post zygotic barriers to reproduction such as timing of mating, sensitivity to pheromones, choice of mating sites or infertility and mismatched gametes. Species formed through sympatric speciation can form interrelationships and undergo coevolution i.e. the evolution of ones species is dependent on the other.  

Allopatric Speciation:

It involves the geographical separation of the parent and new species. These species could be geographically separated by a river, mountain range or land mass.

Although, allopatric species evolve independently, they may develop similar characteristics that serve different functions. Allopatric species in radically different environments undergo convergent evolution i.e. species evolve similar characteristics without any ancestral homology.

Allopatric species that reside in small populations and are under harsh environmental pressures undergo a rapid genetic revolution i.e. genetic drift. This includes the Founder's and bottleneck effect that involve the continuation of a species from very few individuals after a drastic, sudden environmental change.
