Answer:
The answer is Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.

how could the presence or absence of a protein determine a phenotype
Answer:Proteins Dictate Phenotype
Genotype controls phenotype because genes direct the production of proteins . ... Some proteins serve structural functions (for example, in the maintenance of cell and/or tissue shape and rigidity) while others are involved in the transport of molecules and communication between cells.
Answer:
Each protien is essentially a code for a genotype (what the DNA is "saying"). Different genotypes (or DNA combinations) cause the person, plant, animal, etc. to look different.
Mutation may occur in gametes or in body cells. In which cell type is a mutation likely to be source of genetic variation for ?
Answer:
Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN (genotipo) de un ser vivo,1 que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos. Este cambio estará presente en una pequeña proporción de la población (variante) o del organismo (mutación). La unidad genética capaz de mutar es el gen, la unidad de información hereditaria que forma parte del ADN.2
En los seres pluricelulares, las mutaciones solo pueden ser heredadas cuando afectan a las células reproductivas.3 Una consecuencia de las mutaciones puede ser, por ejemplo, una enfermedad genética. Sin embargo, aunque a corto plazo pueden parecer perjudiciales, las mutaciones son esenciales para nuestra existencia a largo plazo. Sin mutación no habría cambio, y sin cambio la vida no podría evolucionar.

Which statement is true of DNA polymerase?
Answer:
b) DNA polymerase can synthesize DNA in the 5' to 3' direction
DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.

What is circulatory system ?A circulatory system is defined as a system in the body that consists heart, blood vessels, arteries, veins and blood that all combined together to supply blood to all parts of body and takes up waste material from it.
Circulatory system have four major components and these are heart, veins, arteries, and blood. These are the four components that combined and form cardiovascular system.
Pulse rate or heart rate is the speed of heart beat measured number of contraction of the heart per minute. The heart rate can vary according to physical needs of human beings. If a person done a physical activity then it's need more blood circulation then pulse rate increases.
The normal pulse rate or heart rate is 60-100 bpm, but when a person is sleeping their pulse rate became 40-60 bpm.
Therefore,The below mentioned levels shows the different structures of heart according to the given diagram:
Label A - Pulmonary Valve
Label B - Tricuspid Valve
Label C - Septum

The first model represents the proton and neutron distribution in the nucleus of four helium isotopes. The second image shows the entry for helium in the periodic table. Based on the information in the periodic table, which is the most common isotope of helium?
Answer:
Helium exist as an isotope, its most common isotope is the one that is placed on the periodic table. The helium atom on the periodic table has two electrons, two protons and two neutrons. The proton and the neutron are located inside the nucleus, this means that two protons and two neutrons can be found inside the helium nucleus. Thus, in the pictures given above, the correct picture is the one that contain four particles.

How does transferring energy into a container of magnetic marbles affect the speed by shaking the container gently?
By the transfer of energy into a container of magnetic marbles the speed changes because of kinetic energy produced by the shaking of container gently. This will lead to phase changes.
What is kinetic energy?All the phase changes in a system are accompanied by the change in the energy of a system. These include transfer of kinetic energy to a system. Changes from a more-ordered state to a less-ordered state are endothermic reactions. Changes from a less-ordered state to a more-ordered state are always exothermic reactions.
A phase change in a system takes place when a matter changes from one state to another state. These changes occur when sufficient amount of energy is supplied to the system or lost from the system. Phase changes also occur when the pressure on the system is changed.

Which scenario causes gene flow
Answer: Migration is one way that genes are transferred from one population to another.
Explanation: Gene flow is caused by a significant change in the population of individuals due to the addition of other individuals whose alleles are slightly different from those of the existing individuals
Answer:
Introgression refers to gene flow from another taxon. While low levels of gene flow between species are not uncommon, it is a serious issue when an introduced invasive species hybridizes with a native species and overwhelms its genetic constitution (genetic swamping). This is a major threat in canids, ducks, fish and plants. For example, exotic rainbow trout introduced into the habitats of native cutthroat trout in the Western United States led to hybrid swarms that eventually overwhelmed the local species. Introgression is readily detected by molecular genetic and genomic methods.
