Provide three ways in which you can tell the difference between a cell in mitosis vs a cell in meiosis. Describe how they are different.
Answers
Answer:
Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells
What is the probability that a hybrid individual with the genotype AabbCcddEeFf will produce a gamete that has the genotype abCdeF
Answers
Answer:
6.25%
Explanation:
Find the number of different gametes that can be produced
number of gametes produced = 2^n
n is the number of allele pairs that are heterozygous
there are 4 heterozygous allele pairs, these are: Aa, Cc, Ee and Ff
2^4 = 16
abCdeF is one of the 16 genotypes that could be produced
to find the percentage, divide 1 and 16 and multiply by 100
1 ÷ 16 = 0.0625
0.0625 × 100 = 6.25
HIV & AIDS. Is this condition still relevant? What are the latest statistics on this condition and can the new drugs really prevent new
infections?
Answers
Answer:
They're still VERY relevant.
Explanation:
In 2019, an estimated 34,800 new HIV infections occurred in the United States. HOWEVER new HIV infections declined 8% from 37,800 in 2015 to 34,800 in 2019. In 2012, the US Food and Drug Administration gave the green light to using daily pills of an HIV medication called Truvada (emtricitabine/tenofovir) to prevent infection. It proved more than 85% effective when taken on schedule. New drugs are still being developed, here's a link from the

Discuss two characteristics of the female pelvis. Why are these characteristics significant?
Answers
Answer:
The general structure of the female pelvis is thinner and less dense, in comparison to the thick and heavy male pelvis, which is designed to support a heavier body build. The true pelvis is wide and shallow in the female, and the pelvic inlet, also known as the superior pelvic aperture is wide, oval and rounded.

Answer:
EeWw
Explanation:
The allele for the earlobe is depicted as e while that of the hairline is w.
A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.
The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww
eeWW x EEww
During meiosis, each genotype will form gametes.
eeWW: eW, eW, eW, eW
EEww: Ew, Ew, Ew, Ew
These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:
eW x Ew
offspring
100% EeWw (see the attached image for the Punnet's square)
The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline.
7. Based on their shape, how would you classify these Fungi? (Which Division do they fit?) I would classify them as sac fungi
Answers
Answer:
To match the features and characteristics.
Explanation:
We can classify these Fungi on the basis of their features and characteristics that resembles to the different divisions of fungi. Fungi are classified in four divisions i.e. the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi). There are specific characteristics of every division of fungi so we have to match the physical features of unknown fungi with these divisions and classify them.

Why do you think type 2 diabetes occurs so much more often than other inheritable diseases? Propose a hypothesis for why this allele has not been eliminated by natural selection.
Which type of species best describes a mouse: opportunistic or equilibrium? Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.
Answers
Answer:
This allele has not been eliminated by natural selection because it may confer an adaptive advantage for particular environmental conditions
Mice and rats are opportunistic species. These species can rapidly adapt to different environmental conditions, while cheetahs are unable to adapt to changing environments.
Explanation:
An allele is a gene variant that may be beneficial, neutral, or deleterious for a particular environment. Different alleles are not eliminated by natural selection against other alleles (even when a priori seem to be deleterious) because they confer a selective advantage in a given environment. For example, the allele for sickle cell anemia is caused by a point mutation which is lethal in homo-zygous individuals, but heterozygous individuals are less likely to die of malaria, thereby this allele has been positively selected in geographic areas where malaria is an endemic disease. Moreover, mice and rats are opportunistic species, i.e., they are species that rapidly adapt to varied living conditions. These species are characterized to have high growth rates and produce many offspring. On the other hand, the cheetah is a highly specialized species that is unable to adapt to changing environments. In consequence, cheetah populations are more prone to become extinct than rat and mice populations.

B. Translate mRNA into a protein.
C. Make a DNA copy of RNA.
D. Translate a protein into mRNA.
Answers
Answer:
A ribosome, formed from two subunits locking together, functions to: (1) Translate encoded information from the cell nucleus provided by messenger ribonucleic acid (mRNA), (2) Link together amino acids selected and collected from the cytoplasm by transfer ribonucleic acid (tRNA). hope that helps❤
A ribosome's primary function is to translate mRNA into a protein. Thus, the correct option is B.
What are Ribosomes?Ribosomes may be defined as the spherical and glandular particles that occur freely in the matrix or remain attached to the Endoplasmic reticulum (RER).
Ribosomes play an important role in protein synthesis by translating mRNA into a protein. They are also involved in the decoding of messages and the construction of peptide bonds.
Therefore, the correct option for this question is B.

c. Usually a single mutation in one gene leads to the simultaneous appearance of the complex character.

e. Usually a single mutation in one gene leads to the simultaneous appearance of the complex character.
Answers
Answer:
b. Often the initial stage in the evolution of a complex character was an adaptation to some unrelated selection pressure.
d. Phylogenetic analysis using cladistics can help reveal the sequence leading to the evolution of a complex character.
Explanation:
The evolutionary developmental program of complex characters can be analyzed by examining synapomorphies, i.e., by examining shared, derived characters common between an ancestor of a given taxonomic group and its descendants. Synapomorphies are able to create evidence for historical relationships between closely related organisms. Moreover, cladistics is a method used to categorize species/taxa into groups called 'clades' based on arranging organisms with similar traits, which can provide useful information on the evolutionary history of complex traits in different species/taxa. In phylogenetics, the analysis of complex characters involves two different stages: 1-character analysis and 2-cladistic analysis. Homology refers to structures that look similar because they were inherited from a common ancestor (i.e., they have a common origin); whereas characters are considered as parts of transformation series. In cladistics, characters used for inferring phylogenetic relationships are considered as hypotheses of homology that are subject to tests of similarity. In consequence, such characters can provide useful information on the evolutionary history of complex traits.

Secretory pancreatic cells are organized in sac-shape structures called acini. These structures are conformed of acinous cells and center-acinous cells that secrete digestive enzymes into the intestine The pancreatic juice flows along the principal pancreatic duct to the bile duct and from there to the small intestine. In the intestine, it degrades fats, carbohydrates, and proteins.
