What adaptations would a plant species need to encounter the effects of an herbivorous insect and what adaptations would the insect need to counter those defenses?
Answer:
The plant defense system incorporates waxy cuticles or bark that are impenetrable in order to protect from insects. They can create complex polymers that lower the plant absorbability to creatures; and poisons that can kill herbivores and insects. Furthermore, plants produce hard shells, and spines (changed leaves), and thorns to shield themselves from herbivores.
Herbivores then again have built up a various scope of physical structures to encourage the utilization of plant material. They have created teeth structures to penetrate or break plant tissues and that mirror their taking care of inclinations. They can create proteins, for example, oxidases (MFOs) and protease that counter and diminish the adequacy of various harmful auxiliary metabolites delivered by plants. They can maintain a strategic distance from plant protections by eating plants specifically in reality.

List the 6 possible genotypes of the four blood types. Identify the parentalgenotypes that could produce children with blood type AO.
Answer:
The different possible genotypes are AA, AO, BB, BO, AB, and OO. These are derived according to the A, B and O blood group model.
The table is given below:
Blood Type Genotype
Blood Type A Genotypes AA or AO
Blood Type B Genotypes BB or BO
Blood Type AB Genotype AB
Blood Type O Genotype OO
The alleles A and B exhibit a greater dominance than O. This is the reason why the Parent of Blood type A will form the Genotype AO.
our blood is able to maintain a ph of about 7.5 because our body acts like a buffer solution. regulating ph is crucial so that our protein structures remain intact and functional. which statement about human protein in the body is not correct
The given question is incomplete as the group of choices are missing, however, the group of choices are given as follows:
Select one
a. Protein consists partially of amine groups that are neutral as a result of protonation (of one H ion)
b.Protein contains deprotonated carboxylate groups, resulting in a negative charge
c. The carboxylate groups in protein act very much like carboxylic acid groups (-COOH), except that they are deprotonated
d. If the human body did not act like a buffer solution, each time you ingested an acid the carboxylate groups would protonate, causing the protein structure to disintegrate.
Answer:
The correct answer (incorrect statement) is : option C.
Explanation:
pH of blood should be remain 7.5 in order to make proteins of the body and blood intact and functional. Human protein have neutral amine group due to the protonation and negative carboxylate group due to the deprotonation.
carboxyl group behave like an acid and carboxylate group behave like a base due to the fact that Carboxylate group (-COO-) is conjugate base of Carboxyl group. Human body acts like buffer to prevent the protein from disintegrate.
Thus, the correct answer is : option c.
When is it okay for a client to become intimately involved with their trainer? A. If both parties consent to it B. Never C. If the trainer's manager knows about it D. Always and involves momentum
Answer:
B. Never

Personal trainers (PT) are individuals hired to improve the fitness (mostly by exercise or dieting) of another person, known as the client. Not only do personal trainers possess the skills and knowledge to go about their jobs, they are also certified, hence, making them professionals at what they do.
Series of conversations, sometimes personal can occur between the PT and the client in order to extract information needed to successfully help the client. However, a personal trainer is mandated to be PROFESSIONAL while performing this role. One of the professional ethics of the job is that personal trainers are NEVER to get into any intimate relationship with their clients. This is a serious offence that can cost a trainer not only his/her job but also professional license.
Answer:
never

A period in 24-point font (.) is about 1mm in diameter. SARS-CoV-2 has a diameter of 80 nm. The prefix “milli” means 1000, which tells you there are 1000 millimeters (mm) in a meter. The prefix “nano” means 109 (1 billion), which tells you there are 1 billion nanometers (nm) in a meter. Approximately how many SARS-CoV-2 viruses could fit in that period? (Hint: There are 106 nm in 1mm).
Answer:
A total of 12,500 SARS-CoV-2 viruses
Explanation:
Consider a trillion against a thousand, there exists a difference of a million, which means a nanometer will be a million times smaller as compared to one millimeter:
see below for a milli divided by nano
1/1000 ÷ 1/1000,000,000 = 1000,000,000 ÷ 1000 = 1000,000
(in reference to the hint given in the question statement)
The question puts one millimeter against 80 nanometers. The calculation for this will be given as follows:
1/1000 ÷ 80/1000,000,000 = 1000,000,000 ÷ 80,000 = 12,500
According to the above working, there are 12,500 SARS-Cov-2 viruses thatg can fit into one period.

5,890,000,000,000 (The distance to the sun in km)
pls help.
Answer:
[tex]D=5.89\times 10^{12}\ km[/tex]
Explanation:
The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.
A number can be written as [tex]x.0\times 10^y[/tex] in scientific notation where x is a real no and y is any integer.
There are 10 zeros in the given number and also there are 12 digits after. It would mean that,
[tex]D=5.89\times 10^{12}\ km[/tex]
So, the distance in scientific notation is : [tex]D=5.89\times 10^{12}\ km[/tex]
Between 1957 and 1961, thousands of expectant women in 30 different nations ingested a common antinausea drug of the time known as thalidomide. A study of _______________ found that if the thalidomide was ingested only after day 54, then no harm occurred to the fetus, but if ingested prior to day 54 the fetus could be born with malformed or absent limbs.
Answer:
A study of those newborn babies
Explanation:
Studying the infants from these pregnant women lead the researchers to find out that this drug interfered with the process of limb formation if the pregnant woman had taken this drug anytime during the 26 days critical for limb formation and development. In this way, it makes for an instance where nurture had disrupted nature.
