An example of __ is the color of betta fish. When a RED fish (GG) is crossed with a YELLOW fish (gg), all of the offspring will be a ORANGE color (Gg)
Answer:
The correct answer is - incomplete dominance.
Explanation:
In the betta fish, there are different types of colors found in the fishes depends on the alleles present in their gene which follows incomplete dominance. Incomplete dominance is an inheritance pattern where a dominant allele does not mask completely and produce a blend of both alleles if present in heterozygous condition.
In the question, It is stated that when a cross between RED fish (GG) and a YELLOW fish (gg) produce orange color fish as offspring (Gg) which is a mix or blend of both alleles Red (dominant) and yellow (recessive).
what is the problem with organizing organisms taxonomically purely based on their physical traits
Answer:
See the answer below
Explanation:
The problem with grouping organisms together taxonomically based on their physical traits is that organisms that not genetically or evolutionally similar would be grouped together. Grouping would be based entirely on superficial similarities instead of combining different features such as genetics, nutrition, the complexity of bodies, etc.
Based on physical traits, for example, all flying organisms will be grouped together. Birds, flying insects, bats, etc. would be grouped together, whereas, they are quite different from one another when it comes to the complexity of bodies and other features. Even though some insects have wings and can fly like birds, insects have exoskeletons and birds do not, the body of birds is more complex than that of insects, and evolutionally, birds are more advanced than insects.
Hence, grouping organisms based on their physical traits only would be too superficial and not reflect the true relationships between organisms.

If an individual has the genotype AaBb, what are the combinations of alleles that would be
found in their gametes?
Answer:
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
I hope this helped
The combinations in the alleles that are carrying out the genotype of AaBb then at that stage the alleles combinations that will be present in their gametes will be AB, ab, Ab and aB.
What is a genotype ?It is defined as the genetic expression of an individual. It defines the traits and the characters that are present in the individual in order to decide the phenotype of an individual.
In the genotype of AaBb, it is the combination as the both of the genes copies are present and in this case due to very obvious reasons it is the capital one that is going to express itself. The other genes are definitely present but with a effect that will be covered out by the dominant one.
The 4 combinations that will be present are AB, ab, Ab and aB where the 1st one where the both of the dominant ones will be present will be carrying the dominant genes, ab in this the recessive ones will be present and in others ones, one dominant and one recessive is present.

Answer: Gas
Explanation:

Nebulae are different luminous regions of the interstellar medium that can be made up of cosmic dust as well as ionized, neutral, or molecular hydrogen, hence option C is correct.
What is dust?All the stuff between stars is referred to as interstellar matter by astronomers, and the complete collection of interstellar matter is referred to as the interstellar medium (ISM). Some interstellar material is gathered into massive clouds that are each referred to as a nebula.
Tiny pieces of solid matter drifting about in the region between stars make up cosmic dust. It's not like the dust you find in your home; instead, it has tiny particles that range in size from collections of just a few molecules to grains that are 0.1 mm in size.
Therefore, an interstellar medium can be made up of cosmic dust as well as ionized, neutral, or molecular hydrogen, hence option C is correct.

Which of the following correctly identifies a lymphatic organ and describes how it
can fight cancer? (2 points)
1) Lymph vessel; removes fluid from tissues
2) Lymph trunk; returns lymph to the blood
3) Spleen; replaces damaged red blood cells
4) Thymus; exposes lymphocytes to antigens
All of the statements correctly identify a lymphatic organ. In vertebrates, the lymphatic organs, also known as the lymphoid system, are an organ system that is a part of the immune system and works in conjunction with the circulatory system.
The Lymphatic OrgansLymphatic vessels, which are found all over your body and transport lymph away from tissues, are a network of capillaries (microvessels) and a huge network of tubes.By emptying into the corresponding subclavian veins, the lymph ducts, which are formed by the lymph trunks, restore lymph to circulation.Red blood cells that are outdated or damaged are eliminated by the spleen, which also removes cellular waste from circulation.Training specific white blood cells known as T-lymphocytes or T-cells is the thymus gland's main job.Hence, all of the statements correctly identify a lymphatic organ.
How lymphatic system fights Cancer?Regional lymph nodes, which are predictive of distant organ metastases and poor survival, are accessible to tumor cells via lymphatic arteries.As the lymph fluid moves through the lymph nodes, it is filtered. B cells and T cells, two types of white blood cells, assault any viruses or bacteria they discover in the lymph.To learn more about the Lymphatic System refer to:

How will antibiotic resistance affect human populations if no action is
taken by our agricultural system?
Answer:
Explanation:
Antibiotic resistance is when the bacteria develop resistance to antibiotics. Antibiotic resistance will affect human populations is no action is taken by our Agricultural system because bacteria itself develop antibiotics resistance and these causes infections on humans and animals. The infections caused by antibiotics resistance bacteria are difficult to treat than those that are not caused by it. These the result in higher cost of medical treatment and treatment of animals, prolonged hospital admission and these can also lead to increased mortality or increase rate of death of Agricultural animals. When there is high mortality of Agricultural products due to this, there won't be enough consumption of these by humans and also there can be passage of these infections to human which can result to mortality.

When the northern hemisphere points toward the sun, the southern hemisphere faces away from the sun. In this instance, it is:
A.
summer in North America, and winter in Australia.
B.
summer in North America and Australia.
C.
winter in North America, and summer in Australia.
Answer:
A
Explanation:
the northern hemisphere is the opposite from the southern hemisphere
Since northern and southern hemisphere are in opposite directions therefore, option (A) is correct.
Why are the seasons reversed in each hemisphere?The axis of rotation of the Earth is inclined with regard to the plane in which it orbits the sun. This is the root reason of the changing of the seasons. When the axis of the earth is aligned with the sun, summer arrives in that hemisphere of the planet. Expect winter to arrive when the axis of the earth is tilted away from the sun.
Different places of Earth receive the Sun's most direct rays throughout the year. When the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, the Northern Hemisphere experiences winter.
