Answer:
The correct answer is "Red shift"
Explanation:
Blue shift: When the source and observer approach one another, the evident frequency increments or apparent wavelength diminishes. Here the Doppler shift is positive. This is known as blue shift.
Red shift: When the source and observer move away from one another, the clear frequency diminishes or apparent wavelength increments. Here the Doppler shift is negative. This is known as red shift.

what are the possible blood types of a child whose parents are both heterozygous for b blood type
Answer:
I believe the answer is:
If both are BB, the child will be BB. If one is BB and one is BO, the child has a 50% chance of being BB and 50% chance of being BO - both of which result in type B. However, if both parents are BO, there is a 25% chance of BB, a 50% chance of BO, and a 25% chance of OO (which results in type O).

Kim and jullio go to a raceway to watch Julio's older brother, Raul compete. Raul's car cover 2.5km in 12 seconds and reaching a speed of 180km/hr.
Let us assume that following:
S=distance
U=initial velocity
V=final velocity
A=acceleration
T=time taken
Given that:-
S=2.5 km
S=2.5×1000 mtr
S=2500 mtr
T=12 seconds
V=180km/hr
=180×1000/3600 m/sec
V=50 mtr/sec
U=0 because in starting his car in rest position
Equation which use for calculations of acceleration,
S = UT + 1/2AT^2
2500 = 0×12 + 1/2A(12)^2
2500 = 0 + 1/2×A×144
2500 = 72×A
A = 2500/72
A = 34.72 m/sec^2
It means when rauls starts the race it's car is in rest position and after that it accelerate at the rate of 34.72 m/sec^2

Jacob a 40 year old man who is 6 foot tall and weighs 225 pounds has been diagnosed with atherosclerosis. What healthcare plan would you design for this patient? prescribe a medication to reduce bad cholesterol and no other changes need to be made. patient is just slightly overweight and she is worrying to much about his health, therefore no change. patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds prescribe a medication that lowers blood pressure and no other changes need to be made.
Answer:
The patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds.
Explanation:
We know that the patient weighs 225 pounds, and his height is 6 feet. With this information, we can determine his Body Mass Index (BMI) using the formula:
BMI= weight/(height)²
BMI= 225/(6)²
BMI= 30.5
Once that we calculated his BMI, we compare the result with the reference chart, here we can see that for his height. he is obese. This coincides with the fact that he has been diagnosed with atherosclerosis. His body has been placing the extra fat in the arteries.
The best plan for Jabob would be to make a lifestyle change to healthier foods and an exercise plan that helps him to lose weight so that his BMI would be approximately 25 and his weight of 195 pounds. Also, this plan will reduce cholesterol levels.

In erythroblastosis fetalis, only pregnant women who are ____ must be treated with injections to prevent their antibodies from attacking their baby s red blood cells
Answer:
Rh-negative
Explanation:
Erythroblastosis fetalis is a clinical condition whereby maternal antibodies begin to attack the fetal red blood cells due to incompatibility in the Rh of mother and fetus. Rh, which stands for Rhesus factor, can either be positive (Rh+) or negative (Rh-).
However, this condition (erythroblastosis fetalis) occurs in mothers/women who are Rh-negative. When an Rh- mother carries a fetus that is Rh+, the antibodies in the white blood cells of the mother identifies the blood cells of the fetus as FOREIGN, hence, begin to attack it.
However, one preventive measure is that pregnant women who are Rh-NEGATIVE must be treated with injections called Rh immunoglobulin to prevent their antibodies from attacking their baby's red blood cells.

beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
Zara should keep the clownfish and the goldfish in separate tanks - the goldfish in a freshwater tank and the clownfish in a salt water tank.
If the goldfish is kept in a salt water tank instead of freshwater, it may die due to dehydration because the salt water would be hypertonic to the cells of the fish. Water would move osmotically from the cells of the fish into the surrounding water and the fish may eventually die due to dehydration.
If the clownfish is kept in freshwater instead of salt water, it may die due to excessive water. The freshwater would be hypotonic to the cells of the fish and water would move osmotically from the surrounding water into the cells of the fish. Eventually, the cells would become turgid and may start lysing, leading to the death of the fish.

In chemiosmosis in mitochondria, protons flow from the intermembrane space into the matrix. In what direction do protons flow during chemiosmosis in chloroplasts
Answer:
Protons flow from the thylakoid space into the stroma of the chloroplast
Explanation:
Chemiosmosis is one of the two events that occur in oxidative phosphorylation (the other being electron transport chain). Chemiosmosis, which occurs to synthesize ATP in both cellular respiration and photosynthesis, is the process whereby protons (H+) move across a membrane via osmosis. In other words, chemiosmosis builds the proton gradient required to power ATP synthesis via the aid of an enzyme called ATP synthase.
In cellular respiration, chemiosmosis occurs when protons flow from the intermembrane space into the matrix while in PHOTOSYNTHESIS, cheniosmosis occurs when protons flow from the thylakoid space into the stroma of the chloroplast.
The flow of protons takes place from the thylakoid space into the stroma of the chloroplast during the chemiosmosis in chloroplasts.
What is chemiosmosis?It is one of the events, which takes place during oxidative phosphorylation. It generally takes place to produce ATP in both the process of photosynthesis and cellular respiration. In the process, the protons move across a membrane through osmosis.
It can also be stated that building of the proton gradient for the synthesis of ATP takes place by chemiosmosis with the help of an enzyme known as ATP synthase.
Chemiosmosis takes place when flow of protons takes place from the intermembrane space into the matrix during cellular respiration. While in photosynthesis, chemiosmosis takes place when flow of protons takes place to the stroma of the chloroplast from the thylakoid space.
Thus, in chloroplasts, chemiosmosis takes place when flow of protons takes place from the thylakoid space into the stroma.

Newton's first law of motion states that an object will remain in motion in a straight line unless compelled to change direction by an external force.
Explain why satellites launched into orbit do not continue moving in a straight line. Make a connection between satellites and planets.
Explanation:
When satellites are launched into orbit, they are able to orbit around planets due to the gravitational force of attraction between the satellite and planet (usually there is no apparent change in motion of the planet because of its relative huge size than the satellite)
This gravitational force is in a different direction than the satellite's motion, therefore it keeps it orbiting around planets and does not continue moving in a straight line.

Answer:
agcttgagt
Explanation:
DNA is a double helix molecule composed of two complementary DNA strands which are in turn composed of four different nucleotide bases: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). In the DNA molecule, G and C are bound together as a base pair, while A and T are bound together as another base pair. This complementary base pairing structure means that both DNA strands are complementary to each other. In this case, since the sequence of one strand is "TCGAACTCA", the complementary DNA strand would have the sequence "AGCTTGAGT".
