If a honeybee is flying 7.0 m/s, what is the kinetic energy (Joules) if its mass is 0.1 g? *
Answer:
2.45 × 10^-3 Joules
Explanation:
Kinetic energy is the energy assumed by a moving object. The kinetic energy, which is measured in Joules (J) is calculated using the formula:
K.E = 1/2 mv^2
Where K.E= kinetic energy
m = mass ( 0.1 g)
v = velocity (7 m/s)
Since Joules is Kgm^2/s^2, the unit of mass must be kilograms (kg), and velocity must be in metre per seconds (m/s).
Hence, we need to convert 0.1 grams to kg by dividing by 1000
1000g = 1kg
0.1g = 0.1/1000 = 0.0001kg
K.E = 1/2 mv^2
K.E = 1/2 × 0.0001 × 7 × 7
K.E = 1/2 × 0.0049
K.E = 0.00245
Hence, K.E = 2.45 × 10^-3 Joules

In my research, I found that the levels of "gonadotropins" in the body are critical to understanding how the drugs Clomid and Ortho Tri-Cyclen work. What are gonadotropins? What role do they play in fertility?
Answer:
Gonadotropins are hormones secreted by the pituitary gland and the placenta.
Explanation:
Gonadotropins are heterodimeric glycoprotein hormones secreted by the endocrine system in vertebrates. Gonadotropins include pituitary hormones such as follicle-stimulating (FSH) and luteinizing (LH) hormones, and placental gonadotropins such as chorionic gonadotropin (CG) chorionic gonadotropin (CG) hormones which are secreted during pregnancy. Gonadotropins play critical roles in growth, ovarian germline cell mitosis/meiosis decision and sex hormone production. In humans, menopausal gonadotropin hormones are secreted by the pituitary gland in order to stimulate ovulation.
Which of the following is not a model organism?
a. Mus musculusCell
b. Drosophila melanogaster
c. Homo sapiens
d. Arabidopsis thaliana
e. Caenorhabditis elegans
Answer:
The correct option is c. Homo sapiens
Explanation:
All options stated are model organisms except Homo sapiens (that is, us humans). One of the conditions to be a model organism is to be easy to breed with in a laboratory setting, which is obviously not possible with humans. The rest (mice, plant, fruit fly, worm) are easy to maintain and have been extensively studied to broaden our understanding of biological processes.
Hom sapiens is not an example of model organisms.
Model organisms are organisms which are used for various studies and
experiments.
They are usually non-human such as insects, animals etc. They are usually
bred in the laboratory under specific conditions to obtain accurate data
about their functions.
It helps scientists in research works to understand biological and other
processes that takes place in them.

Penicillium (the source of the antibiotic penicillin) is a mold that secretes a toxin that kills bacteria and other organisms. Penicillium, however, is not harmed by this toxin. This is an example of:_______
a. predator-prey.
b. commensalism.
c. mutualism.
d. amensalism.
Answer:
This is an example of amensalism (Option d).
Explanation:
The interaction between penicillium and bacteria is a typical example of amensalism.
Amensalism refers to a biological relationship established between two organisms, in which one of them avoids the growth, development, or survival of the other one. In this interaction, one of them is strongly affected by the other one, which does not seem to be affected at all. Antibiosis is referred to as amensalism interaction.
Antibiosis is the interaction in which one of the species secretes a chemical that kills the other species organism or inhibits its actions by causing severe damage. The organism that releases the toxic substance is called the inhibitor. For the inhibitor species, this relationship is neutral because it does not seem to be beneficiated or affected.
Another classic example of amensalism is those plants that secrete chemicals to damage or kill other plants that live near them. In this way, the secretory plants may live and grow with no competition.

Answer:
I can't see your picture
Explanation:
Prompt Comparing amino acid sequences in proteins has been used to determine the relatedness of organisms. Below is a graphic that shows the amino acid sequence differences between different organisms for a protein keratin. Changes in amino acid sequences are known to cause changes in structure of proteins. Part A. Consider species A, D, and E. Using the data provided, describe how the structures of their keratin proteins would compare. Part B. Keratin is made up of about 450 amino acids. Determine the similarity in percentages between species A and B, A and C, and B and C. Explain how amino acid sequences can be used in determining how closely related two species are. Part C. Based on this data, predict which two species would be more closely related to one another. Part D. Justify your predictions to part C.
Answer:
A) Species A and E are very closely related more than species A or E are related to species D.
B) Between A and B = 99.1%
Between species A and C =97.5%
Between species B and C = 97.3%
Similarity in amino acids sequence reflects similarity in DNA sequence, therefore they are used to determine how closely species are related.
C) Species A and E are most closely related
D) Since species A and E are most similar in amino acid sequence, it then means that there genetic sequences are most closely related.
Explanation:
A) The amino acid sequences of keratin, in species A and D have a difference of 19 whereas species A and E are different for only one amino acid. Therefore, it means that keratin in species A and D will have significant differences in their structure whereas between species A and E, they would have very similar structures.
Species D and E have a difference of 20 in their amino acids sequences, therefore, the structure of keratin in both species will have significant differences in their structures.
B) Similarity between A and B:
450 - 4 = 446
As a percentage: 446/450 × 100% = 99.1%
Similarity between A and C:
450 - 11 = 439
As a percentage: 439/450 × 100% = 97.5%
Similarity between B and C:
450 -12 = 438
In percentage: 438/450 × 100% = 97.3%
The DNA sequence of species determines their amino acid sequences because information in DNA is transcribed to RNA which are then used to make proteins. Therefore, if a species are very closely related, they are expected to have very similar genetic sequences (or genes) and thus similar proteins too. This similarity in proteins is observed in the similarity between amino acid sequences in their respective proteins.
C). Species A and E are most closely related.
D) Species A and E have only a single difference in their amino acids sequence for Keratin. This is equal to about 99.7% similarity, the highest similarity observed among all the species compared.

This is the answer to A) Describe how allosteric enzymes are regulated by activator and inhibitor regulatory molecules.
B) Explain how ATP and ADP act as allosteric regulators of enzymes that are responsible for ATP production, and how that is an example of feedback inhibition.
C) What is feedback inhibition? How is the ATP generating pathway discussed in part B an example of feedback inhibition?
Answer:
a} Allosteric regulation is just any form of regulation where the regulatory molecule (an activator or inhibitor) binds to an enzyme someplace other than the active site.The shape of the active site is changed, allowing substrate to bind at a higher affinity.
b) The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP, ADP, and NADH are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.
c) This is a case of feedback inhibition i in which a product feeds back to shut down its pathways.

Which of the following digestive system structures releases sodium bicarbonate into the small intestine, resulting in a change in the pH of chyme from acidic to basic? a. Gallbladder b. Appendix c. Liver d. Pancreas
Answer:
d. Pancreas
Explanation:
The digestive system structure which releases sodium bicarbonate into the small intestine, resulting in a change in the pH of chyme from acidic to basic is called the pancreas. It makes use of the pancreatic duct in releasing the bicarbonates into the small intestine.
The bicarbonates aids the digestive processes and also neutralizes the duodenum from acidity. This is due to the the acidic food from the stomach and is as a result of the stomach being acidic and having acids such as dil. Hcl.
The system that breaks food molecules into smaller pieces and components for absorption and excretion is called the digestive system. It includes organs and secretions required for digesting liquids and food.
The digestive system that releases sodium bicarbonate is:
Option d. Pancreas
The system can be explained as:
The pancreas is an organ that releases sodium bicarbonate and enzymes rich in pancreatic juices to send them to the small intestine through ducts.The acidic chyme produced in the stomach gets passed to the small intestine where the pancreatic secretion along with sodium bicarbonate buffers the acidic juices and inactivates the enzyme pepsin which changes the pH of chyme to basic.The bicarbonate salt neutralizes the acidic nature of chyme and protects the further digestive organs from acidic food.Therefore, the pancreas secretes sodium bicarbonate.

Two autosomal genes control horn color in dragons. Pure-breeding gold-horned dragons were mated to pure-breeding silver-horned dragons. All of the F1 were gold. The F1 were intermated and the F2 generation consisted of 147 gold, 16 silver and 93 bronze. Choose the genetically based phenotypic ratio that should be hypothesized to explain the F2 data.
Answer:
The correct option for the phenotypic ratio in this case is the following
9 : 6 : 1
Explanation:
In order to calculate the ratio, divide the two larger numbers each by the smallest one - which here would be 17.
So, 147 ÷ 17 = 8.7 (rounded off to 9)
And 93 ÷ 17 = 5.6 (rounded off to 6)
This way, '17' is considered as 1. Hence,
Gold : silver : bronze
9 : 6 : 1
What is active transport?
A. The movement of molecules down a concentration gradients from high to low , using no energy.
B. The movement of molecules up a concentration gradient from low to high , using energy
C. The movement of molecules down a concentration gradient from high to low , using energy
D.the movement of molecules up a concentration gradient from low to high , using no energy
Answer:
B. The movement of molecules up a concentration gradient from low to high, using energy
Explanation:
In active transport, the molecules move against the concentration gradient.
This means that the molecules move from an area of low concentration to an area of high concentration.
Because it goes against the concentration gradient, it requires the use of ATP energy.
So, B is correct because it is the movement of molecules from a low to high concentration using energy.

Which is a possible mechanism for why we observe the correlation that red cars are more dangerous than other colored cars?
a. Younger people prefer red cars and have less driving experience
b. Red cars are more difficult to view in the evening and are therefore more prone to accidents in medium-light conditions
c. More sports cars are painted red and people who buy them are more risk-taking
d. All of the above
Answer:
b. Red cars are more difficult to view in the evening and are therefore more prone to accidents in medium-light conditions
Explanation:
Red colored cars are more dangerous than other colored cars because red color cars can not be seen in the evening or dark environment so that's why more accidents were observed with red color cars as compared to another color cars. Red is a vibrant color and one of the most dangerous cars colors. People sometimes confused with traffic lights, brake lights etc and accident happen.

What did B. F. Skinner believe drove one's behaviors? (Site 1)
Answer:
Environment
Explanation:
B.F Skinner was of the belief that the environment of a person drove or influenced his behavior. His opinion was that human beings have a particular way of behaving which requires special kinds of responses and that as this goes on, humans will adapt and start behaving in a certain kind of way.
He strongly believed that because we learn things differently and in different environments, that is why there are differences in human behavior and one's environment can shape his personality.
