(a) Describe the first interaction that triggers signaling to begin in a target cell.
Answer:
a signal molecule locks to a receptor protein (like lock and key),causes shape change in receptor then creates a specific reaction inside the cell that eventually triggers the cell response. State where signal receptors may be located in target cells.
What does the field of biology study
Answer:
Field biology is a sub-discipline of biology that focuses on different levels of biological organization such as organism, population, community, and ecosystem. As its name suggest, this field requires researchers to spend time in remote areas in order to observe a variety of organisms.
Explanation:
Biologists study the structure, function, growth, origin, evolution and distribution of living organisms. There are generally considered to be at least nine "umbrella" fields of biology, each of which consists of multiple subfields.
Answer:
Living organisims
Explanation:
When is osmosis used by
cells to move water across a selectively permeable
membrane?
A. Osmosis is used by cells when large molecules pass freely across the selectively permeable membrane.
B. Osmosis is used by cells to create equilibrium when large molecules can't pass through the membrane.
C. Osmosis is constantly in process inside of a cell, regardless of equilibrum.
Answer:
B.
Explanation:
Osmosis moves water from the part of the membrane with less solutes to the part with more solutes. This will continue until the cell or whatever it is reaches equilibrium.

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.

How are ethanol and glucose similar in structure and function?
Choose all correct answers.
A. They are both carbon-based molecules.
B. They are both hydrocarbons.
I c. They both store energy in chemical bonds.
D. They are both used as fuel.
Check
An organic compound that has an OH group on its side chain is called ethanol. It is flammable and a volatile liquid. Whereas, Glucose is a simple sugar molecule that has carbon and aldehyde groups.
The correct answer is:
Option A. They are both carbon-based molecules.Option C. They both store energy in chemical bonds.Option D. They are both used as fuel.This can be explained as:
Ethanol and glucose both have carbon atoms in their structures. Ethanol is written as C₂H₅OH and Glucose as C₆H₁₂O₆.The energy in both the molecules is stored in their bonds.Glucose is used as fuel in living organisms while ethanol is a bio-fuel derived from microorganisms.Therefore, ethanol and glucose are similar in structures and some functions.

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.
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.
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.
