What are the stages of Meiosis I and Meiosis II in order as the happen.

Answers

Prophase I 

DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent. Chromosomal condensation allows these to be viewed in the microscope. Note that the bivalent has two chromosomes and four chromatids, with one chromosome coming from each parent.Prometaphase I 

The nuclear membrane disappears. One kinetochore forms per chromosome rather than one per chromatid, and the chromosomes attached to spindle fibers begin to move.Metaphase I 

Bivalents, each composed of two chromosomes (four chromatids) align at the metaphase plate. The orientation is random, with either parental homologue on a side. This means that there is a 50-50 chance for the daughter cells to get either the mother's or father's homologue for each chromosome.Anaphase I 

Chiasmata separate. Chromosomes, each with two chromatids, move to separate poles. Each of the daughter cells is now haploid (23 chromosomes), but each chromosome has two chromatids.Telophase I 

Nuclear envelopes may reform, or the cell may quickly start meiosis II.Cytokinesis 

Analogous to mitosis where two complete daughter cells form.
Meiosis I: 

Prophase I - Homologus chromosomes pair up (synapsis) and form a tetrad. Sometimes non-sister chromatids exchange genetic information during the process of crossing over. 

Metaphase I- Tetrads line up at the center of the cell. 

Anaphase I - Homologous pairs are split up. 

Telophase I/Cytokinesis - Two daugher cells form that have half the chromosome number of the parent cell but each chromosome consists of a pair of sister chromatids. 

Interkinesis - break period 

Meiosis II: 

Prophase II - A new spindle forms 

Metaphase II- Each chromosome lines up at the middle of the cell. 

Anaphase II - The sister chromatids are separated and move to opposite ends of the cell. 

Telophase II - Two new nuclei are formed in each cell. Each nucleus contains a haplod (n) number of chromosomes. 

Cytokinesis- End result of meiosis is 4 haploid daughter cells

Although all these are necessary to provide to children, which is considered a basic need. A. medical care
B. transpiration
C. entertainment
D. education

Answers

I believe the answer would be: "D: Education " 
So two of the four options can be correct. It just depends on who you ask and how in-depth you want to think about this question.

Lets define basic needs in layman's term: it can be seen as supplies available that help in long-term well-being of someone in a physical manner.

healthcare aka medical care is considered a basic need along with education. Medical care can prolong the life of a child and education can help a child or an adult get a job in which they can earn a descent amount of income so they can support themselves, which also helps extend their life and knowledge is power. Many poor people live short lives because of lack of medical care and education. If people are educated then they can learn about the do's and don'ts in health. I think medical care and education can intertwine.

It just depends on how you see it or how your professor sees it. If you explain how medical care and education intertwine then he/she might see that and  give you credit based on which ever option you select. I would just double check with what he/she wants just to be on the safe side.

Hopefully this helped and best of luck to you!!!

A new herbal supplement is on the market that claims to build immunity and prevent illness. The best response to this claim is to

Answers

The best response to the claims is to research the information using several sources before taking the supplement. It is important to research more information on the new product before taking the supplement because we never know what will be the effect of the drug to our body. It is best to gather more details and see whether it is safe to take or not. 

Answer:

A) research the information using several sources before taking the supplement.

Explanation:

A population of ground mice consist of 500 individuals. You are interested in the gene that codes for for a color and find out there are 580 dominant alleles in this population. What is the allele frequency for the dominant allele? What is the allele frequency for the recessive allele? (show your work)

Answers

Answer:

0,58

Explanation:

Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given locus/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic locus, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).

Choose the correct order of classifying organisms in the Linnaean system. A.kingdom→phylum→ class→ order→ genus→ family → species B.kingdom→phylum→class→order→family→genus→species C.species→order→family→genus →class →phylum→kingdom

Answers

The correct answer is option B, kingdom→phylum→class→order→family→genus→species

Reason:

There are basically seven orders of classification in Linnaeus's Classification System (in present time) arranged in descending order

Kingdom→phylum→class→order→family→genus→species  

The Domain is the largest and most inclusive group and consists of organisms that share few characteristics while the species is the smallest and most exclusive group and consists of organism that possess similarity up to an extent where they can breed among themselves to produce offsprings.  
The answer is B. You can remember it by King Phillip Came Over For Galloping Stallions.
