The correct answers are :
a) syndrome Could be autosomal recessive or dominant
b) If it is autosomal recessive - no ,
and if it is autosomal dominant - yes, (II-4) - Aa
c) probability of the another child :
Autosomal recessive: Aa x aa 50%
Autosomal dominant: aa x Aa 50%
Explanation:
a) Marfan syndrome could be inherited by the autosomal recessive or dominant pattern on the basis of following characters according the pedigree gives:
- transmitted by anyone regardless of sex male or female
- characters should not skip generations
- A cross between affected person and an normal person should produce approximately half of the affected offspring.
b) Assuming that autosomal dominant than there is two possibilities :
1) in case of I 2 genotype is heterozygous which means it is Aa which will produce Aa Aa aa and aa with crossing with aa as per pedigree however it is incorrect according the offspring given in II.
2) If I 2 is AA- then offspring will be Aa, Aa, Aa and Aa. which is correct according the pedigree.
thus, the answer is - Aa
c) the punnet square as per question is :
II2 - Aa × II1 - aa
A a
a Aa aa
a Aa aa
similar with autosomal recessive
thus, the correct answer is 2 out of 4 that is 50%

Answers
Answer:
Meiosis is the mechanism used for producing gametes in multicellular organisms whereas it does
unicellular organisms.
Explanation:
Meiosis is a kind of cell division used mainly by sexually-reproducing organisms, whether unicellular or multicellular, to produce gametes i.e. meiosis only occurs during gamete formation.
In sexual reproduction, gametes must fuse in a process called fertilization. This gametes, however, must each possess half of the chromosome number of the individual organism. Meiosis is the process that ensures that the chromosome number of the gametes is reduced by half i.e. diploid (2n) to haploid (n).
Therefore, meiosis is the process of gamete formation in sexually-reproducing unicellular or multicellular organisms.
DDT was once considered a "silver bullet" that would permanently eradicate insect pests. Instead, DDT is largely useless against many insects because they are resistant. Propose a hypothesis as to why these organisms have become resistant to the chemical.
Answers
Answer:
None of the individual insects should have possessed genomes that made them resistant to DDT.
Explanation:
Pesticides such as DDT have been considered one of the best way to kill insects in the past. But with time, farmers have observed that this is not an authentic method. This is because the insects can gain resistance to the pests if they are exposed to the pesticide again and again. Even they could transmit these resistant genes in their offsprings. Hence, DDT will become useless against insects over time.
Describe the two patterns Wilson observed regarding the distribution of ants on Melanesian islands.
Answers
Answer:
human invasions and expansion/contraction cycles during glacial-interglacial periods
Explanation:
In 1961, the biologist Edward Osborne Wilson studied the distributional, behavioral and morphological characteristics of ants living in the Melanesian archipelago. After his study, Wilson then proposed a hypothesis to explain the biogeographic dynamics of Melanesian ants which has been referred to as the 'taxon cycles'. Taxon cycles are defined by stages of expansion and contraction in the range of distribution of species combined with evolutionary adaptive changes in their ecological niches. These cycles can be represented by historical processes of invasion that resemble human invasions. In the last years, it has been shown that Wilson's hypothesis is supported by predictions obtained by modern methodologies for investigating taxon cycles (i.e., evolutionary phylogenetic methods).

limonite
Mary and Jim's sample
What do you notice? What can you conclude from the test?
Answers
Answer:
The streak colors are different. Limonite streaks show yellow.
Explanation:
The minerals in the rocks they found are not limonite
According to Mary and Jim. The colors of the streaks are different. This is because every piece of rock has different origins and with respect to that, they obtain colors.
What is Limonite?Limonite may be defined as iron ore that possesses a brown earth pigment. In ancient times, it was utilized as an ornamental stone for small carved items such as beads and seals. It is also known as brown hematite or brown iron ore.
The limonite generally occurs in the cavity of sedimentary rocks as well as its coating. It also presents as iron rust. This experiment clearly demonstrates the different colors of the streak.
The ores of limonite are yellowish in color and consist of 40 to 60% of iron metal. The colors of other ores are significantly different from the streak of limonite.
Therefore, the colors of the streaks are different. This is because every piece of rock has different origins and with respect to that, they obtain colors.

Answers
Answer:
How the eye view an object.
As the object appear before the eye,
Light enter the cornea, the domeshape that cover the front eye.
The light then enter the pupil through the cornea.
The light then hit the eye lens, a transparent structure that focuses the light through the virteous humour, a gel like substance that surrond the retina.
The retina then receive the light that was focused by the eyes lens and transform it to electrical impulses.
The electrical impulses is then transmitted to the person through the optic nerve,
The optic nerve then interpret it as the object view.
Explanation.
Eyes are organs of the visual system. They provide both humans and animals with the ability to receive and process visual information, thereby enabling different photo response functions that are independent of vision. Eyes detect light and convert it to electrical impulses in neurons. The optic nerve then send it to the brain which is then is interpreted as what is seen.

Justin is a 24-month-old male with multiple food allergies, including milk, eggs, and peanuts. At six months old a cooking utensil that had been used to cook eggs touched his arm and his mother noticed a significant dermatological response. As a result, Justin’s pediatrician advised her to avoid eggs, cow’s milk, and peanuts in Justin’s diet until food allergy testing could be done at two years of age. Fortunately, Justin hasn’t had any negative reactions to soy milk. Food allergy testing has confirmed that Justin needs to continue to avoid cow’s milk and peanuts. His pediatrician plans to conduct food allergy testing annually and advises his mother that Justin will likely be able to outgrow the milk allergy. Justin is referred to a registered dietitian for an assessment of his growth and nutrition intake. His mother reports that he is able to feed himself and she has noticed no problems with chewing and swallowing. A 24-hour dietary recall shows Justin consumed the following foods:
Fortified soy milk (4 ounces), rice cereal, bananas, grilled soy-cheese sandwich, fortified soy milk (4 ounces), green beans, apricots, orange juice (8 ounces), apple slices, almond butter on toast, apple juice (8 ounces), roast turkey, baked potato, green peas, and fortified soy milk (4 ounces).

O Consider the diagram that depicts the lysogenic and lytic cycles. The steps of the lysogenic cycle are shown. In Step A, attachment and entry occurs. In step B, the provirus is formed. In step C, the cell begins to divide. In step D, the provirus leaves. In step E, the virus is replicated and assembled. In step F, lysis and release of the virus occurs. In which step of the diagram is the provirus formed? step A step B step E step F
Answers
The correct answer is Step B
Explanation:
The lysogenic and lytic cycles are processes of replication for viruses. These two processes involve different steps. In general, the first stage involves attachment and penetration as the virus enters the host cell. This step is followed by the provirus, which means the genome of the virus is integrated into the DNA of the cell, this step is also mentioned in the model as part of step B "the provirus is formed". Moreover, the formation of the provirus is key as the nutrients of the host cell and genome are used for replication. Thus, in the diagram, the provirus is formed in step B.

Answer:
When pollen from the pollen part of the flower (the anther) gets its way into the germination part (the stigma) of the SAME plant.
It's kinda weird because many plants have both "male" and "female" seexy bits on the same flower.
Explanation:
Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperm-style plants).
There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the pollen part (anther) of one flower to the germination part (stigma/ovule) of another flower on the same flowering plant.
Answer:
This is the pollination of flower by pollen grains from the same flower on the same plant.
Explanation: OR:
This is also when pollen from the same plant arrives at the stigma of a flower or at the OVULE.
Many plants that can be self pollinating can also be cross pollinating.
Examples of self pollinating plants are: wheat, tomatoes, barley, e.t.c.
This is also the transfer of pollen from the anther to the stigma of the same flower or the flower of the plant with the same clone.

Which reason best explains why bacteria are good at causing infections in other organisms? It would not be able to divide. Bacteria are transmitted easily and reproduce quickly. Bacteria evolve slowly as they pass on genetic information. Bacteria are easily killed by a host’s immune system or antibiotics.
Answers
Answer:
Bacteria are transmitted easily and reproduce quickly
Explanation:
Bacteria are organisms that have a single cell. The process of reproduction of the bacteria is binary fission. The parent cell divides into the daughter cell. The DNA of the parent cell gets copied and gets divided by forming the identical daughter cells. Some bacteria have nutritional values in them while the others are infectious. They can divide at an alarming rate if they receive favorable conditions. Also, they are easily communicable and transmittable. It is because of this reason that the bacteria are good at causing infections in other organisms.

A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
B. Phosphorylates glycogen phosphorylase
C. Phosphorlyates Casein Kinase.
D. Is activated by the insulin signaling pathway.
Answers
Answer:
A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
Explanation:
Glycogen synthase kinase (GSK) is a type of enzyme capable of phosphorylating serine and threonine residues on the glycogen synthase (GS). The insulin hormone activates the synthesis of glycogen by dephosphorylating GS, but it is a mechanism that depends on the previous phosphorylation of GS by Casein Kinase (CK). GSK is also known to phosphorylate the insulin receptor (IRS), and thus controlling glucose metabolism.

As amino acids are put together, their ______determines the way in which they will fold into a three-dimensional structure. It is the________ of the folded structure that determines its function.
Answers
A sequence is a section of DNA that is required to make a protein. The section of DNA undergoes transcription in order to synthesize a protein. As amino acids are put together, their order determines the way in which they will fold into a three-dimensional structure. It is the shape of the folded structure that determines its function.
Gene is a section of DNA that is required to make a protein. The section of DNA undergoes translation in order to synthesize a protein. As amino acids are put together, their sequence determines the way in which they will fold into a three-dimensional structure.
What is a gene?A gene is a segment of DNA that is required to produce one protein. Because they code for proteins made up of hundreds or thousands of amino acids, genes are typically hundreds or thousands of base pairs long.
Translation is the process by which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins in molecular biology and genetics.
The amino acid sequence of a protein drives the folding and intramolecular bonding of the linear amino acid chain, that will determines the protein's unique three-dimensional structure.
The folded structure's conformation determines its function, which is directly dependent on the protein's linear amino acid sequence.
Thus, it can be concluded that, section of DNA referred to as gene is involved in protein synthesis, i.e., translation. In this amino acid sequence will decide the type of fold.

Answers
Answer:
Moving genetic code from the nucleus to a ribosome
forming part of the ribosome
Carrying amino acids to a ribosome
controlling splicing by marking intron and exon sequences
Explanation:
Ribonucleic acid (RNA) is a key molecule that has diverse biological functions. In the first place, the messenger RNA (mRNA) is an RNA version whose function is to transmit the code from the DNA within the nucleus to the cytoplasm during protein synthesis. Second, the ribosomal ribonucleic acid (rRNA) represents a structural component of ribosomes where proteins are synthesized. Third, the transfer ribonucleic acids (tRNAs) represent another important class of RNA version that attach amino acids to transport them to the ribosomes in order to decode an mRNA into a protein. Finally, RNA splicing is the processing of RNA to eliminate non-coding introns from the precursor mRNA (pre-mRNA) molecule to form the final mature mRNA transcript.
If the regulator protein of the arginine regulon is mutated such that it can not bind arginine, which of the following describes the phenotype of the bacterium with such a mutation?
a) inducible
b) repressible
c) uninducible
d) constitutive
e) none of these
Answers
Answer:
The answer is a repressive mutation (the term is similar to b option).
Explanation:
In bacteria, the arginine regulon consists of a dozen genes required during the transport and biosynthesis of arginine (arg genes), these genes are controlled as a single unit. In prokaryotes, the concept of regulon is similar to the operon; however, an operon is composed of a group of genes linearly localized on bacterial chromosome, while a regulon can be formed by genes localized in different chromosome regions. Moreover, in eukaryotes, this concept is also used in order to indicate a set of linked genes that are regulated by the same regulatory gene sequence. A repressive mutation in a positive regulator of the arg regulon may trigger the inhibition of arg genes by affecting their ability to bind arginine.
