Explanation:
Labrador retrievers are traditionally black, brown, or yellow. The B allele codes for black fur, and the b allele codes for brown fur. The E allele allows the pigment to be deposited in the fur, while the e allele doesn't allow the pigment to be deposited. If one lab has the genotype bbee, and another lab has the genotype BbEe, what is the chance that an offspring will be brown
Answer:
25% of offspring will be brown
Explanation:
4 out of 16 of will be brown
to convert this to a percentage do:
4 ÷ 16 × 100 = 25
Punnett squares are in the image
Brown offspring are circled
Why is it important to center the object you want to look at in your field of view before changing to a higher magnification objective lens? A. So the object is still in your field of view at the higher magnification. B. So you can always see the entire object at the higher magnification. C. So you do not damage the higher magnification objective lens.
Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.
Q4: Describe how crossing over can lead to new variations in genes.
Answer:
Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

How would the introduction of a predator species affect the stability of an
ecosystem?
A. The native prey might not be able to protect itself against the new
predator, so the prey population would probably decline rapidly.
B. The stability would not change because the new predator would
simply replace the native predator.
C. The new predator would be unable to hunt effectively for native
prey, so the stability would not change.
D. The stability of the ecosystem would increase as a result of the
introduction of a new predator species.

Sort the sentences based on the type of relationship they describe. Sea lampreys hatch eggs on fish and feed on the fish. Clown fish help sea anemones catch prey while using the sea anemones for protection. Mosquitoes suck blood from the bodies of organisms. Ants provide protection to acacia trees while receiving nutrients from the trees. Mutualism Parasitism Ants reserved PLZ HELP
Answer:
1: Parasitism
2: mutualism
3: parasitism
4: mutualism
Explanation: Hope this helps and have a great day!!
The sentences describe different types of symbiotic relationships between organisms are: Parasitism, Mutualism, Commensalism
1. Parasitism: Sea lampreys hatch eggs on fish and feed on the fish.
In parasitism, one organism benefits (the sea lampreys) at the expense of the other (the fish) by feeding on its tissues.
2. Mutualism: Clownfish help sea anemones catch prey while using the sea anemones for protection.
This sentence describes mutualism, where both clownfish and sea anemones benefit from the relationship. Clownfish protect sea anemones from predators, while they, in turn, provide a safe haven for the clownfish.
3. Parasitism: Mosquitoes suck blood from the bodies of organisms.
Mosquitoes exemplify parasitism as they feed on the blood of other organisms, taking nutrients without providing any benefit in return.
4. Mutualism: Ants provide protection to acacia trees while receiving nutrients from the trees.
This sentence represents mutualism, where ants defend acacia trees from herbivores, and in return, they receive nutrients and shelter from the trees.
5. Commensalism: Ants reserved.
The term "reserved" here seems to be incomplete, but assuming it refers to ants residing in a certain place, it would represent commensalism. Commensalism describes a relationship where one organism benefits, and the other is neither helped nor harmed significantly.
In summary, the sentences describe mutualism, parasitism, and possibly commensalism, showcasing the diverse interactions that can occur in ecological communities.

A marathon runner is running a race. During the race the marathon runners heart rate and breathing increases. Which of the following explains why the marathon runners' body is responding in this way?
Answer:
Warmer temperatures increase your heart rate. In addition to pumping more blood to the muscles, your heart also transports more blood to the skin in order to cool it. Increased demand causes your heart to beat faster -- anywhere from 20 to 40 beats per minute higher than normal.

What does a DNA repair mutation cause in the Cell cycle?
Answer:
Mutation rates increase substantially in cells defective in DNA mismatch repair or in homologous recombinational repair (HRR). Chromosomal rearrangements and aneuploidy also increase in HRR defective cells. Higher levels of DNA damage not only cause increased mutation, but also cause increased epimutation.

What is the difference between global effects and local effects.
Answer:
golbal means around the world but local means next to you
Answer:
A global effect generally affects, as the term implies, the world as a whole, or at least a major part of the world, while a local effect would be just in a distinctive area.
For example, if the world is heating up due to CO2 emissions, it heats up in an global effect, resulting in the median temperature rising in all areas of the world. However, the world heating up may only mean a drought in distinctive areas that are typically already leaning towards the drier side (local effect), while the others receive a greater than usual volume of water due to rising temperatures.

What characteristic could provide a species with a better chance of surviving a drastic environmental change?
(A) A small population size
(B) A highly diversified gene pool
(C) specialized cells within the body
(D) Many individuals with the recessive trait
A highly diversified gene pool could provide a species with a better chance of surviving a drastic environmental change. So, the correct option is B.
What is Diversified Gene pool?Greater genetic diversity within a population is made possible by a diverse gene pool, which raises the possibility that at least some members of the population will exhibit features that are more adapted to the new environment.
This variety can develop as a result of gene flow from other populations or mutations. The number of people having the recessive trait or a limited population size, however, would not always give an advantage in enduring environmental change. A species may have a better chance of surviving a severe environmental shift if its gene pool is extremely varied.
Therefore, the correct option is B.

(D) It would not be able to store water or protect itself from viruses
Explanation:
Water moves in and out of a cell in conformity with the concentration gradient formed between the membrane of the cell and the extracellular solution. The process whereby the water moves from a region of low solute concentration to a high solute concentration via a semi-permeable membrane is called OSMOSIS.
In this case, the solute concentration of the blood cannot be regulated, hence, it rises. This causes the solute concentration of the blood to be high or is said to be hypertonic than the cell's. This creates an osmotic gradient causing water to flow out of the hypotonic (low solute concentration) cell into the hypertonic extracellular environment (blood). Once water flows out of the cell as a result of osmosis, the cell shrinks or shrivels i.e. reduce in size.
Explain the importance of organic compounds to the cell.
Answer:
Organic compounds essential to human functioning include carbohydrates, lipids, proteins, and nucleotides. ... Monomers are single units of organic compounds. They bond by dehydration synthesis to form polymers, which can in turn be broken by hydrolysis. Carbohydrate compounds provide essential body fuel.
