Which of the following choices correctly shows an example of the way energy flows in an ecosystem? A. Rattlesnake to Hawk to Kangaroo Rat to Fungus to Cactus B. Fungus to Hawk toRattlesnake to Kangaroo Rat to Cactus C. Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus D. Cactus to Fungus to Kangaroo Rat to Hawk to Rattlesnake
ANSWER:
C. Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus
EXPLANATION
Living organisms in an ecosystem obtain energy by feeding on one another. As one organisms feeds on the other, ENERGY FLOWS. However, the flow of energy is UNIDIRECTIONAL. The flow of energy is represented by a FOOD CHAIN where the arrow signals which organism is feeding on which.
According to this question, a typical example of energy flow in a terrestrial ecosystem is as follows:
Cactus → Kangaroo rat → Rattlesnake → Hawk → Fungus
In the above food chain, energy flows as cactus plant (producer) is fed on by kangaroo rat (primary consumer), which is fed on by rattlesnake (secondary consumer), which is fed on by hawk (tertiary consumer). Hawk is decomposed by fungi (decomposer) when it dies. Energy flows in this direction.
Hence, an example of the way energy flows in an ecosystem is represented by Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus
An organism is _______ for a gene if it has two copies of the same allele for the gene.
The genotype of an organism and the interaction of the genotype with the environment determine the organism’s _______, or observable characteristics.
The law of independent assortment states that the separation of alleles for one gene are independent of that of other genes, unless the genes are _______.
Mendel’s law of _______ governs which allele is expressed in an individual.
Respond to the following based on your reading.
In the previous section, you learned that the allele for brown eyes (B) is dominant, and blue (b) and green eyes (g) are recessive, while green eyes are dominant over blue eyes. What eye color would someone with the following genotypes exhibit? (a) BB, (b) Bb, (c) gb, (d) Bg, (e) bb.
Discuss the law of segregation and explain why each organism has two copies of the gene for each trait expressed.
What type of experiments did Mendel conduct, and what did he want to find out about the heritability of the seven traits he chose to study?
Answer:
1. Purebred (N.B: the exact word is considered a foul word)
2. Phenotype
3. Linked
4. Segregation
5) (a) BB- Brown eyes
(b) Bb- brown eyes
(c) gb- green eyes
(d) Bg- brown eyes
(e) bb- blue eyes
The other questions are explained below
Explanation:
1. A purebred organism is that which possess two copies of the same alleles in its genotype. An allele is a contrasting form of a gene. If the two alleles are the same, the organism is said to be purebred.
2. Phenotype of an organism is the observable characteristics of the organism. It is determined by the organism's genotype in interaction with its environment.
3. Mendel's law of independent assortment states that the alleles of a gene will separate into gametes independently of another gene unless the genes are linked. Linked genes are genes that are too close to each other on a chromosome and hence, do not sort independently. They're rather inherited together.
4. Mendel’s law of Segregation governs which allele is expressed in an individual. According to this law, an organism will express the allele it randomly receives from each parent. If an organism receives two different alleles, it will express the allele that is dominant. In other words, an organism will only express the recessive trait if it receives two recessive alleles from both parents.
5. a) BB- Brown eyes because the organism is purebred for the dominant (brown) allele
(b) Bb- brown eyes because the brown allele (B) will mask the expression of blue allele (b) and express itself.
(c) gb- green eyes because the allele for green eyes (g) is dominant over the allele for blue eyes.
(d) Bg- brown eyes because the brown allele (B) is dominant over the allele for green eyes (g), hence, it will mask its expression
(e) bb- blue eyes because the organism is purebred for the blue allele i.e. same recessive (blue) alleles in the gene.
6. The law of segregation as proposed by Mendel states that the alleles of a gene will separate into gametes during gamete formation (meiosis). This is done in such a way that each gamete contains only one allele of each gene. Hence, an organisms will contain two copies of a gene because they receive each copy (allele) from each parent during fusion of their gametes.
7. Mendel conducted an hybridization experiment i.e. a cross involving two individuals that possess different traits. He did this in order to find out how different traits/characteristics in organisms were transferred from one generation to another. Mendel chose the pea plant for his experiment because they could easily be manipulated for self and cross pollination. Mendel studied seven (7) different traits or characteristics in pea plants including height, seed shape, seed color, flower color etc.

NAD is reduced by the action of enzymes. NAD can receive electrons for use in chemiosmosis. NAD can be recycled many times.
Answer:
"NAD has more chemical energy than NADH" is the FALSE statement.
Explanation:
It is totally true that NAD can be recycled many times, it can actually receive electrons for use in chemiosmosis and is reduced by the action of enzymed. During both glycolysis and the Krebs cycle. All these statements are true. But when it comes to NAD and NADH, it is false that NAD has more chemical energy than NADH. There is actually more energy in one NADH, that can lose electrons to transfer energy.

It grows and develops.
It is made of cells.
2.Compare a virus to a unicellular organism.(1 point)
Viruses reproduce through asexual reproduction; unicellular organisms need a host cell.
Neither unicellular organisms nor viruses respond to stimuli.
Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.
Viruses need energy; unicellular organisms do not need energy.
3.Summarize the lytic cycle.(1 point)
A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.
A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
4.Differentiate between the lysogenic and lytic cycles.(1 point)
The host cell copies its own DNA during the lytic cycle.
The host cell is destroyed during the lytic cycle.
The virus injects DNA into the host cell during the lysogenic cycle.
Viral proteins are synthesized during the lysogenic cycle.
5.Infer why doctors recommend people, especially elderly and those with weak immune systems, get the flu vaccine every year.(1 point)

Please i really need help
Answer:
1. It grows and develops
2. Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.
3. A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
4. The host cell is destroyed during the lytic cycle.
5. They should get the flu vaccine because their bodies do not build up resistance.
Explanation:
These are the answers I chose from when i did it 10 minutes ago, they wont let me go back to the quick check to confirm it, but this was the best I could do.
The trait of living things that's depicted by a virus that mutates is that it evolves.
The difference between a virus and a unicellular organism is that Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.
The lytic cycle is when a virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
The difference between the lysogenic cycle and the lytic cycles is that the host cell is destroyed during the lytic cycle.
The reason why doctors recommend people, especially the elderly and those with weak immune systems, get the flu vaccine every year is because they should get the flu vaccine because viruses mutate.
It should be noted that when a virus mutates, it shows its ability to evolve. In such a case, there's transformation and development regarding the virus.
People are advised to get the flu vaccine every year because viruses mutate. In this case, getting the flu vaccine will help protect the person from the virus.
Getting a flu vaccine is vital especially for the people that have a low immune system as well as for the older people who are already weak.
