Answer: some energy is lost from the pyramid, energy is transferred from bottom (producers) to top, but in decreasing amounts.
Explanation: total energy is conserved, but not necessarily within the energy pyramid, which is an open system where energy is lost from the pyramid, mainly as heat but also as sound.
Energy is transferred up the pyramid but the amount transferred at each stage is less because of losses outside the pyramid.
Predict the method that estrogen will initiate the reception process in its cell signaling pathway.
a. Estrogen will bind to a transmembrane signal receptor that activates cell-signaling pathways.
b. Estrogen will act as a steroid signal receptor that activates ion channel proteins.
c. Estrogen will serve as a second messenger that activates cell-signaling pathways.
d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.
Answer:
d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.
Explanation:
Estrogens are small lipophilic molecules synthesized from cholesterol. This steroid hormone (estrogen) is able to directly enter into the cell nucleus to bind with their corresponding receptors. Subsequently, estrogen-receptor binding stimulates these receptors to form dimeric structures that bind to DNA and thus activate gene expression. Estrogen receptors interact with DNA and activate gene expression through zinc finger domains composed of four (4) cysteine residues surrounding a zinc atom.
Some roses have streaks of pink and streaks of red to give a striped effect to
their petals. Which inheritance pattern that you have read about today do you think
might be involved in the coloring of these roses? Explain.
Answer:
The correct answer is - incomplete dominance is the correct answer.
Explanation:
Incomplete dominance is the inheritance where there is no complete dominance takes place and where is the mix of both alleles trait mixes or blends in the offspring.
The red or purple cross with white plants flower cross the incomplete inheritance takes place to produce a striped effect to their petals.

A sequence of DNA has 120 nucleotides (it is not a complete sequence).
How
many amino acids would be in the resulting polypeptide chain?
a. 120 amino acids
b. 240 amino acids
c. 40 amino acids
d. 12 amino acids
Answer:40
Explanation: a codon is three nucleotides. Provided that the sequence does not include a STOP codon, the polypeptide would have 40 amino acids
40 amino acids would be in the resulting polypeptide chain of a sequence of DNA that has 120 nucleotides.
CODONS:
A codon is a triplet nucleotide sequence in an mRNA molecule that encodes a particular amino acid. Each codon specifies an amino acid. A codon is made up of three nucleotides, whose combination determines the amino acid that is encoded. According to this question, a sequence of DNA has 120 nucleotides. This means that the number of codons that is accommodated in this sequence is 120/3 = 40 codons. Since 1 codon specifies 1 amino acid, therefore, 40 codons will specify 40 amino acids.Learn more about codons at: https://brainly.com/question/19153211?referrer=searchResults

The muscular system and the skeletal system are two different organs. But they're often reffered to jointly as the muscoloskeletal system. Why do you think the word musculoskeletal exists? What similarities in functions do you think the muscular system and skeletal system have?
Answer:
Both helps in the movement of our body.
Explanation:
The muscular system and skeletal system perform similar function which is movement of body and muscles. Muscular system is made up of skeletal, smooth and cardiac muscles, due to these muscles we are able to work by using our muscles while on the other hand, skeletal system is made up of bones which provides structure to our body and responsible for movement of our body.
What is something all eukaryotic cells have in common?
A.)All Cells are round
B.)All cells have a nucleus
C.)All cells have a cell wall
D.)All cells have cytoplasm
Answer:
We can immediately rule out option A, because not all cells are round. We can also rule out option C because not all cells have a cell wall. Animal cells, for instance, do not.
Can you choose more than one option? Because if so, the answers would be both B and D. All cells, no matter what type, have cytoplasm. Only eukaryotic cells have a true nucleus.

Provide a summary of what happens during DNA replication using the following words: Helicase, DNA
polymerase, Primase, Ligase, Parent strand, new strand, nucleotides, and semi-conservative model.
Answer:
Please find the summary of what happens during DNA replication below
Explanation:
DNA replication is the process by which a DNA molecule is duplicated into two identical copies. It occurs in the nucleus of the cell prior to any cellular division. The process includes:
- The double stranded DNA is first unwound by an enzyme called DNA HELICASE into a replication fork consisting of two single strands of DNA.
- Another enzyme called DNA POLYMERASE binds to the DNA and begins to add NUCLEOTIDES to each strand using complementary base pairing rule i.e. A-T, G-C. To do this, short sequences of RNA called PRIMER are synthesized by an enzyme called PRIMASE, which serves as building block for DNA polymerase to act.
- However, DNA POLYMERASE can only work in the 5'-3' direction i.e. on the leading strand which runs from 3'-5' direction. Short pieces of DNA called OKAZAKI fragments are synthesized on the lagging strand, which runs from 5'-3' direction.
- An enzyme called LIGASE joins the okazaki fragments together into a whole DNA on the lagging strand.
After the replication process which follows the SEMI-CONSERVATIVE MODEL of replication, each DNA molecule will contain one old strand called PARENT STRAND and one NEW strand.

Isostasy leads to isostatic adjustment if mass is redistributed. Erosion redistributes rock from the mountain to the sediment in the
basin. Which statement does NOT reflect what occurs when erosion happens?
-)))
A)
Mass increases at the crust.
B)
Less mass on the mountain causes uplift.
0
The crust beneath the mountain thins and rises.
D)
The mass of the crust decreases and the mass of the mantle increases.
Answer: It's A.
Explanation: I am doing UsatestPrep, Now I got this answer wrong, but afterwards it told me the right answer is! "Mass increases at the crust" I got the answer wrong originally because I chose B but it's actually A.
Answer:
Its A because Mass increases at the crust. . Mass is actually decreasing due to erosion of the crust, isostatic adjustment will thus, cause the mantle mass to increase over time.

Insulin is a hormone produced by some pancreatic cells. Scientists have isolated the DNA sequence that codes for human insulin production Which of the following best predicts the effect of inserting this gene into the DNA of a bacterial cell?
А. The recombinant bacterium will produce human insulin using its own transcription and translation machinery.
B. The recombinant bacterium will not transcribe the human insulin gene because this gene is not normally found in the bacterial genome.
C. The recombinant bacterium will transcribe the gene but will be unable to translate the mRNA.
D. The recombinant bacterium will die because it has been exposed to foreign DNA
Answer:
А. The recombinant bacterium will produce human insulin using its own transcription and translation machinery
Explanation:
This question is describing genetic engineering, which aims at producing desirable traits in organisms. In this case, the gene that encodes insulin protein in humans is inserted into the plasmid (extra-chromosomal DNA) of a bacterium. The plasmid is then inserted back into the bacterium to become a RECOMBINANT BACTERIUM.
The recombinant bacterium containing the insulin gene will produce human insulin (protein) using its own transcription and translation machinery. This genetic engineering procedure is used to mass produce insulin protein, which is administered as medicine to humans who cannot produce the protein.
