structural adaptations of phloem
Answer:
strong
Explanation:
Answer:
The cells that make up the phloem are adapted to their function. Each sieve tube has a perforated end so its cytoplasm connects one cell to the next Companion cells. transport of substances in the phloem requires energy. One or more companion cells attached to each sieve tube provide this energy.
Explanation:
A man heterozygous for blood type A marries a woman heterozygous for blood type B. What could be the possible blood types of their offspring?
Answer:
Heterozygous A: AO (remember, O type blood is a recessive allele. It's masked by A)
Heterozygous B: BB (h0m0zygous)
AO x BB --> AB, BO
Therefore, the genotypes of their offspring will be 1 AB to 1 BO, while the phenotypes will be 1 AB blood to 1 B blood.

Are fibrous proteins heavier than globular proteins in terms of molecular weight? Why?
Answer:
Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.
When comparing proteins and polysaccharides, the following similarities
can be identified:
Both consist of linked monomers via the process of dehydration reactions
Both consist of linked monomers via the process of hydrolysis.
Both consist of linked sugars via the process of dehydration synthesis.
O O
Both consist of linked amino acids via the process of hydrolysis.
Answer:
The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.
Explanation:
Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.
The process of polymer formation is called polymerization, and one of the reactions that this process allows is polycondensation, where a water molecule is lost in the union of monomers.
The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.
The other options are not correct, because
Hydrolysis produces the rupture of molecules, with the intervention of water.Only polysaccharides are sugars bound by the dehydration synthesis process.Only proteins consist of amino acids linked through the process of hydrolysis.Individuals of the same species that live in the same species that live in the same area_________

In fruit flies, curved wings are recessive to straight wings, and ebony body is recessive to gray body. A cross was made between true-breeding flies with curved wings and gray bodies to flies with true-breeding straight wings and ebony bodies. The F1 offspring were then mated to flies with curved wings and ebony bodies to produce an F2 generation.
1. Diagram the genotypes of this cross, starting with the parental generation and ending with the F2 generation.
2. What are the predicted phenotypic ratios of this F2 generation?
3. Suppose the following data were obtained for this F2 generation:
114 curved wings, ebony body
105 curved wings, gray body
111 straight wings, gray body
114 straight wings, ebony body
Conduct a chi-square analysis to determine if the experimental data are consistent with the expected outcome based on Mendel's laws.
Answer:
Population of F2 generation will be formed on 9:3:3:1 ratio.
Explanation:
The predicted phenotypic ratios of F2 generation is 9:3:3:1. Ratio 9 represents straight wings, gray body which are dominant allele, ratio 3 represents hybrid flies having curved wings, gray body, ratio 3 represents hybrid flies having curved wings, ebony body and ratio 1 indicates flies with curved wings, ebony body. The population of F2 generation will be formed on the above ratio.
The study of genes is called genetics.
The correct answer is Population of the F2 generation will be formed on the 9:3:3:1 ratio.
What is a dihybrid cross?When more than two characters are crossed to form a new breed is called a dihybrid cross.
The predicted phenotypic ratio of F2 generation is 9:3:3:1. Ratio 9 represents straight wings, gray bodies which are dominant allele, ratio 3 represents hybrid flies having curved wings, gray body, ratio 3 represents hybrid flies having curved wings, ebony body and ratio 1 indicates flies with curved wings, ebony body. The population of the F2 generation will be formed on the above ratio.
Hence, the correct answer to the question is mentioned above.

55) Cells require which of the following to form cilia or flagella?
A) centrosomes
B) ribosomes
C) actin
D) A and B only
E) A, B, and C
Answer: D) A and B only
Explanation:
Centrosomes and Ribosomes are both present in the animal cell with both of them having different roles. Centrosomes have roles in cell divisions as they maintain chromosome number during the process and Ribosomes are in charge of the synthetization of proteins.
These two share a role together which is that they are both needed by the cell in order to form either cilia or flagella.

If the frequency of the disorder in the population is 0.0070, what is the percentage of heterozygous carriers
Answer:
15.322 %
Explanation:
Supposing that this is a recessive disorder and the population is in Hardy-Weinberg equilibrium:
p² + 2pq + q² = 1, where
1- the genotypic frequency of the homo-zygous dominant allele is p²,
2- the genotypic frequency homo-zygous recessive allele is q², and
3- the genotypic frequency heterozygous allele is 2pq
Therefore:
q² = 0.007 >> q = √ 0.007 = 0,0836
p = 1 - q = 1 - 0,0836 = 0.9164
2pq = 2 x 0.9164 x 0,0836 = 0.15322 (or 15.322 %)
What prevents acetylcholine from accumulating in the neuromuscular junction and causing a sustained contraction in a normal individual
Answer:
Botulinum toxin
Explanation:
Botulinum toxin is known to hinder the release of acetylcholine into the synaptic cleft at the neuromuscular junction.
This leads to acetylcholine not attaching to its receptors and eventually leading to the inability to have muscle contractions.
Hence, in this case, the correct answer is Botulinum toxin prevents acetylcholine from accumulating in the neuromuscular junction in individuals.

What are the charges both inside and outside of the neuron before you click the stimulate neuron button?
Answer:
The correct approach is "Negative and Positive".
Explanation:
Just outside of the neurons, the electrostatic interactions seem to be extremely favorable or positive (+) as well as the ion mostly with the greatest proportion was indeed sodium. Throughout intracellular space, a large amount of protein would be negatively charged, or even just potassium channels predominate. Under those same circumstances, the ion channels also seem to be inaccessible.For this specific purpose, this same lying down the neuron, before obtaining a stimulus, introduces positively charged on the external social but instead negative (-) inside though.

3. On a particular planet, it takes 850 J for a 50 kg remote probe to launch
itself up 2 m. What is the gravitational field strength on the planet?
Answer:
the gravitational field strength is 8.5 N/kg .
Explanation:
PE = mgh
where,
PE is Potential Energy
m is the mass
g (a) is the acceleration
h is the height
Substitute the value we get
→ 850 = 50×a × 2
→ 850 = 100×a
→ a = 850/100
→ a = 8.5m/s²
Acceleration is 8.5m/s².
Now, Calculating the Gravitational Field Strength
