Explanation:
Genetically engineered foods (GE foods), or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering techniques allow for the introduction of new traits as well as greater control over traits when compared to previous methods, such as selective breeding and mutation breeding.[
Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its unsuccessful Flavr Savr delayed-ripening tomato. Most food modifications have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton. Genetically modified crops have been engineered for resistance to pathogens and herbicides and for better nutrient profiles. GM livestock has been developed, although, as of 2015, none were on the market.

Select the homologous structures.
a. human arm
b. whale's flipper
c. bird's wing
d. cat's leg
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.

Which sentence describes a disadvantage of using nuclear fision to produce
electricity?
A. Fission changes one type of atom into another type of atom,
B. Fission produces only a small amount of energy
c. Uncontrolled fission reactions can result in dangerous explosions,
O D. Fission requires conditions that exist only in the cores of stars.
Answer is C
Answer:
C. Uncontrolled fission reactions can result in dangerous expolosions
Explanation:
The sentence describes a disadvantage of using nuclear fision to produce electricity is uncontrolled fission reactions can result in dangerous explosions. Thus, option C is correct.
Why nuclear fission is different from nuclear fusion?The two ways that nuclear fission is different from nuclear fusion include are the nuclear fission involves one large atom splitting into two smaller atoms and nuclear fission releases a huge amount of energy as the nuclear fusion involves the combination of two or more atoms while Nuclear fission involves one large atom splitting into two smaller atoms.
They both take place in the nucleus of the atom and can be used to generate electricity. They both release energy with the process of nuclear fusion releasing more than nuclear fission.
Fission produces only a small amount of energy and uncontrolled fission reactions can result in dangerous explosions as the Fission requires conditions that exist only in the cores of stars.
Therefore, The sentence describes a disadvantage of using nuclear fision to produce electricity is uncontrolled fission reactions can result in dangerous explosions. Thus, option C is correct.

Explanation:
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...

2. a cell
3. organ system
4.Tissues are groups of similar cells that have a common function. While an organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.
5.
nervous system - The nervous helps the whole body communicate, our body needs to communicate so we can actually do things like breathing.
respiratory system - The respiratory system gives cells the oxygen they need to survive, and cells keep humans alive. Humans cannot survive without breathing.
digestive system - The digestive system is important for breaking down foods into nutrients, those nutrients are then used to heal and nourish the human body. The digestive system also helps us pass toxic wastes that build up in our bodies, so we don't get sick.

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.

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.

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.

Write two statements expressing the relationships between voltage and current and resistance and current.
Explanation:
The current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.If we increase the amount of voltage applied, and do not change the resistance, we will also increase the current.
