The zebra mussel is a highly invasive species that was accidentally introduced to the Great Lakes region of the United States in the 1980s. The map below shows the distribution of zebra mussels in 2010. • Zebra mussel location What is the primary reason the large-scale spread of zebra mussels concerns scientists? Zebra mussels out-compete native mussel species. © Zebra mussels are a freshwater species. Zebra mussels are a desired food for humans. Zebra mussels are eaten by some fish and birds.
Answers
Answer:
Although the map showing the distribution of mussels in not included but the question can be answered based on general understanding of invasive species. The answer is:
Zebra mussels out-compete native mussel species.
Explanation:
Invasive species in biology refers to the species of an organism that is foreign to a particular area/location with an ability to grow very rapidly to the point of being a threat to the local species of organisms that are native to the area.
This is the case of the Zebra mussel, which was accidentally introduced to the Great Lakes region of the United States in the 1980s. It is a major concern for scientists (like every other invasive species) because of its potential to outgrow and outcompete native mussel species i.e mussel species naturally found in the lake.

3.Explain how energy from the sun can eventually be used for active transport in the alimentary canal
(7 marks)
Answers
Answer:
See the answer below
Explanation:
First of all, the radiation energy from the sun is converted to chemical energy by green plants in a process known as photosynthesis. The equation of the process is represented below:
[tex]6CO_2 + 6H_20 + (radiation) -->C_6H_1_2O_6 + 6O_2[/tex]
The chemical energy is locked up as carbohydrate in the green plants. When humans or any other animal consumes green plants or any of their products, the carbohydrate is broken down through a process known as respiration. The equation of the process is as below:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + energy[/tex]
The locked-up energy - usually in the form of ATP - becomes available to be used for various metabolic processes in the body, including active transport in the alimentary canal.
In some cases, humans or animals generally do not consume green plants directly. They consume organisms that consume green plants. Such humans are still able to extract some of the energy through respiration and use it for their metabolic processes.
A mating between a true-breeding purple-flowered pea plant and a true-breeding white-flowered pea plant would produce a:______.A) True-breeding variety.B) Inbred organism.C) F1 generation.D) P generation.E) F2generation.
Answers
Answer:
The correct answer would be - option C) F1 generation
Explanation:
The true breeding varieties are the offspring that have same phenotype as the the parents and contain same allele for a specific trait. When there is mating between two true breeding varieties offspring would be hybrid.
P generations is the generation of the parents in other words, matting in between parents known as p generation whereas the very first generation after p generation is known as F1 generation or filial generation and also the hybrid of P generation.
Thus, the correct answer is option C). F1 generation

Compare the energy values of a carbohydrate molecule versus a fat molecule.
Answers
Answer:
A fat molecule is stored with a lot of energy where as a carbohydrate molecule is a long chain of carbon atoms.
Carbohydrates and fats are nutrients which provide energy to the body and since calories(kilocalorie) tell how much energy a molecule of a nutrient contain, We can compare their energy values by first changing to kilocalorie.
Now, 1 gram of Carbohydrates contain 4 kilo calories while 1 gram of fat contains 9 kilo calorie of energy.
Let us consider a piece of bread containing
20g of carbohydrate molecule and
14g of fat molecule.
We will see that
carbohydrate will have 20 x 4 =80kcal and
fat will have 14 x 9=126kcal
Even with the carbohydrate having more mass than Fat, Fat ended up havng more energy value than it.See here for related answer: https://brainly.com/question/2006114

One strand of the DNA serves as a direct template for the new strand, and the other strand is pieced together and comprises a new strand. This statement best describes _____.
Answers
Answer:
DNA replication is the answer
One strand of DNA serves as a direct template for the new strand, and the other strand is pieced together and comprises the new strand. This statement is related to DNA replication.
What is DNA replication?DNA replication is the process by which genetic materials are copied. In this process, the DNA helix unwinds and each DNA strand opens. Enzymes such as DNA polymerase access the single strand and add complementary bases to the already existing DNA or parental DNA.
The DNA replication takes place from the 5' end to the 3' end. The DNA elongation continues from 5' to 3' taking the 3' to 5' parental template DNA strand. This strand is called a "leading strand," as the newly synthesized DNA is formed continuously. The other template DNA strand of parental DNA, with 5' to 3', doesn't elongate continuously in replication. Patches of short DNA are formed. This is called a lagging strand.
Hence, one strand, the leading strand, is formed continuously while the lagging strand is pieced together. This statement best describes DNA replication process.

Answers
Answer:
Key mediated transport
Explanation:
The molecules across the membrane are transported through active or passive transport. The molecules can pass through protein channels only in the Carrier-Mediated Transport. Thus, option D is correct.
What is Carrier-Mediated Transport?Carrier-Mediated Transport is the active transport that requires energy or other co-transporters to move the molecules across the semi-permeable membrane. The Carrier-Mediated uses the energy-dependent pathway and receptors to transport the molecules.
Carrier-Mediated Transport uses the properties of competition, specificity, and saturation to transport the molecules. The molecule can pass only if they have a specific shape to that of the receptor channel.
Therefore, option D. molecules can pass through protein channels only in the Carrier-Mediated Transport.

Answers
Answer:
Because of the remaining actin-myosin bonds.
Explanation:
After death, the body can still continue to produce energy as ATP and that ATP interacts with the myosin within the muscles, causing the muscles to remain contracted and tense. This is what causes rigor mortis, the body is unable to break the bonds between actin and myosin.
I hope this answer helps.
Answer: ATP NEEDED TO BREAK ACTIN-MYOSIN BONDS
Explanation: ATP (Adenosine Triphosphate) is the substance that allows energy to flow into the muscles,this energy helps the muscle to contract and work well so without this chemical (ATP), energy can't flow into the muscles and the muscle in-turn cannot function or contract.
When an individual dies,the body stiffens as a result of loss of Adenosine Triphosphate.
The muscles then stays in a contracted state until ATP becomes binded to myosin, thereafter, myosin and actin filaments will be released from one another.

How will the movement of substances be altered in the phloem during spring season? Why?
Answers
Answer:
The phloem is responsible for transporting food from leaves to other parts of the plant.
The transport of pholem is bidirectional and changes the movement of particles according to the season. Generally, the transportation occurs in the direction of the source to sink but in spring season the direction is opposite that is from sink to source because the source and sink are n opposite sides. So in spring season, the stem tubers are sources and the growing leaves are sinks.
