Which coin paradox calls for the ability to assess when more force is needed?
krek1111 [17]
The answer to this question would be: the more force used, the less effective it is.

Sometimes, more force in counterinsurgency can cause a less effectivity. It was called paradox because with more force you should expect more results and more efficiency. But more force could mean higher possibility for collateral damage which can cause loss, not gain. An overwhelming force also might be pictured as brutality.

• describe how heterozygote advantage and frequency-dependent selection promote balanced polymorphism and maintains genetic dive
cestrela7 [59]

Answer;

Heterozygote advantage occurs when heterozygotes have a higher fitness than do both homozygotes. In frequency-dependant selection, the fitness of a phenotype declines it it becomes too common in the population.

Explanation;

The heterozygotes have both alleles, which is needed for genetic variation. Heterozygotes are essential for there to be genetic variation in a population. In other words it is when When a single copy of a disease allele doesn't result in a disease but instead is good for the person or organism that carries it, we say that allele has a heterozygote advantage. For example a sickle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.

-Frequency-dependent selection occurs when the fitness of a genotype depends on its frequency. It is possible for the fitness of a genotype to increase (positively frequency-dependent) or decrease (negatively frequency-dependent) as the genotype frequency in the population increases.

Which feature is shown ONLY by higher invertebrates, as compared to lower invertebrates?
Lisa [10]

The correct answer is C. The three germ layers.


The feature which is only shows higher invertebrates as compared to lower invertebrates is referred to s the three germ layers.


Germ layers is termed as the primary layer of cells which forms during embryogenesis. Three germ layers which are invertebrates are pronounced as eumetazoans which includes animals.

An example of an animal which produces two germ layers is Cnidarian which are endoderm and ectoderm and makes them diploblastic.

Chordates produce third layer which is mesoderm and makes triploblastic. Germ layers they give rise to all animals organs and tissues under process known as organogenesis.
