in a certain fish, blue scales (BB) and red scales (bb) are codominant. when a fish has the hybrid genotype, it has patchwork of blue and red scales. what is the genotype for blue fish. what is the genotype for red fish. what is the genotype for patchwork fish.
Answer:
BB is blue
bb is red
Bb is patchwork
Explanation:
It can't really be codominant since lowercase letters are recessive, and condomance needs 2 dominant alleles of a different types. So really it should be BB for blue, RR for red and BR for patchwork...
Some cities hang their traffic
lights from left to right, rather
than from top to bottom.
Explain why this might cause a
problem for a driver with red-green perception deficiency.
Answer:
The angle and location
Explanation:
There are some who can't perceive the order of red and green together. Having it angled up and down is safer because you know out of common sense that red is on top and green is on the bottom. Having it sideways makes the light elevated on the same level, deceiving the eye better.
Some cities hang their traffic lights from left to right rather than from top to bottom, and this causes problems for drivers, as the left-to-right orientation of traffic lights can pose a problem for drivers with red-green perception deficiencies.
What role do traffic lights play?Traffic lights typically have three colors, such as red, yellow, and green, which are arranged in a vertical orientation in most cities, but in some cities, traffic lights are hung in a horizontal or left-to-right orientation, which can be challenging for those who have red-green color blindness. The traffic lights are there to prevent accidents.
Hence, some cities hang their traffic lights from left to right rather than from top to bottom, and this causes problems for drivers, as the left-to-right orientation of traffic lights can pose a problem for drivers with red-green perception deficiencies.

Answer:
Flipper of a whale and bird's wing are homologous structures.
For more better explanation see below.
Explanation:
Flipper of Whale is homologus to the wing of a bird. Homologous organs - The structure which are similar in their morphology, anatomy, genetics and embryology, but dissimilar in their functions.
Flipper of whale and wing of bird has similar morphology and anatomy, but differ in their functions according to their species as well as the habitat where they live in.
A dolphin’s flipper, bird’s wing, cat’s leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.

Two tubes A & B were set up as shown above. Both tubes were left indoors for 50 minutes and then taken outdoors for another 50 minutes. The tubes were weighed every 10 minutes. The table shows the results obtained.
Answer:
Explanation:
Question A
Evaporation happens because fast moving molecules break out of the surface of the water. The fact that there is part of a plant in the water means that the water travels up to the leaves where it evaporates. There are two sources of evaporation in test tube A and only one in B.
Question B
The Cotton plug in the top of the test tubes slows the process down. There are still molecules that are escaping but the cotton absorbs them especially in test tube B. The molecules are free to go in test tube A. They make their way to the leaves where they evaporate.
Part C
You'll have to do the rest of this yourself. The graph for Test Tube A should be less (closer to the x axis) than B.

Why does a vasectomy not affect urine flow?
(FETAL PIG LAB)
Answer:
A vasectomy has no effect on libido, erections, or urination. The amount of semen a man ejaculates will not change after a vasectomy; the only difference is that there are no sperm in the ejaculate. The testicles will also continue to produce testosterone at the same rate.
Explanation:
Vasectomy is the surgical method of male sterilization or permanent contraception. During this process, the male vasa deferentia are cut and sealed to prevent sperm from the urethra and thereby prevent fertilization.
Vasectomy is done in the case of males. Many males are concerned about urination and erection. It is the different duct where urine uses the ureter and sperm uses the gas deferens.
Vasectomy is a method of contraception that has no effect on libido, urination, and erection. Hence the vasectomy does not affect urine flow.

A farmer uses DDT to kill insects in his field. The first year nearly all of the insects were killed. By the fourth year, however, nearly all of the insects survived the DDT treatment. Explain the process of natural selection in this population of insects. Include these words - mutation, phenotype, variation, resistance, adaptation, and differential survival.
Answer:
Explanation:
Selection is the greatest force that alters gene frequency and brings about variation that is evidence in a population. There are both natural and artificial selection.
Mutation is one of the force that alters population frequency it is an heritable change that is sudden and occur in the gene, it can be induced or caused naturally.
The insect survived the DDT used because over the years they have build immunity and resistance against the chemical, they now mutate and produce gene that becomes resistance to the chemical and now adapted or adaptable to the environment. Natural selection helps in the continuous perpetuation of the new phenotype and a new differential survival rate.

O A plant cell because it has a cell wall.
A fungal cell because it has a vacuole.
O A plant cell because it has a vacuole.
O A fungal cell because it has no chloroplasts.
Answer:
A Comparison of Cells Commonly Seen in Lab
Bacteria: prokaryotic. Very small. No nucleus, no chloroplasts, no mitochondria. Do have a cell wall.
Plant cells: eukaryotic. Relatively large. Have a nucleus, have mitochondria, sometimes have chloroplasts. Have a large central vacuole and a cell wall.
Animal cells: eukaryotic. Relatively large. Have a nucleus and mitochondria. Never have chloroplasts. Lack a cell wall, and have no central vacuole.
...
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
This cell was alive and at 1000x magnification when it was photographed.

A researcher prepares a suspension of mitochondria from tissue and monitors the respiration of the mitochondria by the rate of oxygen (O2) consumption in the presence of pyruvate. When the researcher adds an inhibitor of isocitrate dehydrogenase to the suspension, oxygen consumption (respiration) stops.
Answer and explanation:
The mitochondria are the organelle responsible for respiration, which leads to the production of ATP - the most important molecule in energy transfer.
For respiration to happen, there are several processes involving chemical reactions that take place in the mitochondria. These mechanisms are: oxidative decarboxylation, Krebs cycle, and oxidative phosphorylation. Glycolysis is also important for these processes to occur, but this particular case happens outside of the mitochondria.
Pyruvate is an important precursor of the Krebs cycle, also called 'the citric acid cycle'. The researcher observes the functioning of the mitochondria in presence of pyruvate, but then adds an inhibitor of isocitrate dehydrogenase. This inhibitor cancels out the action of the isocitrate dehydrogenase, which is a key enzyme in the Krebs cycle. By inhibiting this enzyme, the cycle cannot continue, and respiration stops.

There is oil that is coming up on the beach from the waves. What most likely caused the oil to get in the water?
A) Animals have carried oil from land to the water.
B) An accident caused an oil rig to spill oil into the ocean.
C) The wind has blown oil into the ocean from land.
D) The oil has come from a crack in the ocean floor.
Answer:
it would be B
Explanation:
it makes the most sense
An accident caused an oil rig to spill oil into the ocean, most likely caused the oil to get in the water, hence option B is correct.
What are the causes of oil spills?Although incidents involving tankers, barges, pipelines, refineries, drilling rigs, and storage facilities are the most common source of oil spills in rivers, bays, and the ocean, they can also involve recreational boats and marinas. People making errors or being negligent can result in spills.
The source of between one-third and fifty percent of the oil in the water are natural seeps. These are specific locations on the seafloor where springs of oil and gas can be seen rising buoyantly from oil-rich sediments that have been naturally raised up close to the earth's surface.
Therefore, option B is correct.
