Answer:
Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons. A covalent bond forms when the bonded atoms have a lower total energy than that of widely separated atoms.

Explanation:
When a membrane protein is radioactively labeled during synthesis and followed through the various organelles in the secretory pathway, all the radioactivity is concentrated in the cis-Golgi apparatus six hours after the protein synthesis. This suggests that the protein
a. is misfolded and being degraded in the cis-Golgi.
b. contains a KDEL sequence near its C-terminus.
c. has a membrane-spanning domain length equals the
d. thickness of the cis-Golgi membrane.
e. was imported directly into the cis-Golgi posttranslationally.
f. has a mannose-6-phosphate tag.
Answer:
C. has a membrane-spanning domain length equals the thickness of the cis-Golgi membrane.
Explanation:
Secretory pathway is the pathway that transport proteins to the cell surface membrane. For this, the membrane proteins are labeled radioactively and move through the various organelles to carry the proteins to the surface membrane.
After six hours, all the radioactivity is concentrated in the cis-Golgi apparatus this means that The protein carries membrane-spanning domain which widens or make the cis-Golgi menbrane thick.
Hence, the correct answer is "C".

what observations do you have about the bacteria cell
Answer:
Bacteria cells have no membrane bound organelles.Bacteria cells are prokaryotic.Bacteria cells have cell walls.Bacteria cells have strong flexible layers surrounding their cell membranes.Bacteria are called prokaryotes; they lack a nucleus and do not present organelles in the cytoplasm, their observable characteristics are:
The nuclear region of bacteria is not surrounded by a membrane, and consists simply of a single circular double-stranded DNA molecule, which constitutes the bacterium's chromosome (genome).The bacterial cell wall is composed of a macromolecular network called peptidoglycan or murein.The cell wall that gives them their shape and provides mechanical protection, since bacteria are found in environments that can have different concentrations of solute.
Glycocalyx is the polysaccharide-containing structure located on the outer side of the bacterial cell wall.Some bacteria produce flagella, these are long, thin appendages that serve as locomotion organelles.Axial filament a series of fibrils that arise at the ends of the cell below the outer sheath and follow a helical path around the cell.The fibria are structures that enable bacteria to adhere to inert surfaces or to form films on the surface of liquids.Therefore, we can conclude that bacteria are microorganisms that contain structures required for their growth and self-replication, without them these microorganisms lose their integrity.

A willingness to accept different ideas that may not agree with their hypothesis is called what?
Answer:
ad hoc hypotheses
Explanation:
This statement could be used for any hypothesis in which the results (different ideas) do not agree with their hypothesis. In other words, there were no verifiable tests that could make valid the accepted hypothesis.
Thus, the researcher only accepted the hypothesis without a sound basis for doing so.

What are the differences between prokaryotic and eukaryotic gene expression? Group of answer choices Regulation of transcription is identical in both.
Answer:
See the answer below
Explanation:
The gene expression involves a series of steps that have to do with encoding the information in genes as mRNA - transcription - and the translation of the codes into proteins - translation.
The process of transcription and translation happens within the same space in prokaryotic cells. Since they have neither nuclei nor membrane-bound organelles, both transcription and translation happen in the cytoplasmic space of the cell simultaneously.
However, in eukaryotic cells, transcription happens in the nucleus because the DNA is located within it. Once this takes place, the mRNA produced is transported outside the nucleus into the cytoplasm where they engage with the ribosome and tRNA in a translation process.

2 ways pea plants pollinate
Answer:
Pea plants are naturally self pollinating.......
Explanation:
As they are self pollinating , there's no any way for their pollination . But we can also pollinate the pea plants manually
Answer:
Method 1 : Self-Pollination
Peas are naturally self-pollinating and self-pollination happens before the flowers open.
In self-pollination, pollen grains from anthers on one plant are transferred to stigmas of flowers on the same plant.
Method 2 : Cross -pollination
Peas can be cross-pollinated by hand, simply by ;
opening the flower buds to remove their pollen-producing stamen which prevents self-pollination and dusting the pollen from one plant to the stigma of another.
Explanation:
Pinky's science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder.
Answer:
See the answer below
Explanation:
The complete question: Pinky's science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder. Consider if data was collected consisting of the average number of cricket chirps at different temperatures in her backyard. What's the independent variable?
The independent variable would be the temperature.
Independent variables are variables that produce effects on another variable while remaining unaffected themselves. They can be manipulated in the course of a research in order to measure the kind of effects they exert on other variables - the dependent variables to be specific. The dependent variables are the actual variables needed to test the hypothesis of a research.
In this case, a variation in temperature was observed to have an effect on the chirping frequency of crickets. Hence, the independent variable would be the temperature.
Why is the amount of fertilizer known as the independent variable?
Answer:
You can think of an independent variable is the variable that is being varied by you the experimenter or scientist; it is the input/"cause"/the tunable variable. A dependent variable is the response/output/"effect".
There is also the control variable, which are variables that stay constant throughout. You generally have only one independent variable and many control variables so that you can properly disentangle cause and effect.
A simple example might be say you want to know if a certain brand of fertilizer helps your crops grow. You want to see how much fertilizer you need for optimal growth without using too much. What is the independent and dependent variable? (Highlight below for the answer!)
The independent variable is the amount of fertilizer you put on the crop. It is the variable that you, as the tester, vary yourself. The dependent variable is how much your crop grows. What about the control? It is the crop you choose to use the fertilizer on (e.g., corn, wheat, peas). Certainly, comparing the influence of fertilizer between corn and peas would not definitely tell you whether the fertilizer is effective; if you compared two different crops, you would have other confounding variables out of your control, so you want to test it only on one crop at a time.
I put cause and effect in quotes because you may run into one of many cause/effect fallacies (or mistaken beliefs). It is possible (and often happens in research) where you plot what you think is an independent and its dependent variable, but the reality is quite different! There are two common types- spurious relationships and spurious correlations. A spurious relationship is one in which a direct cause/effect relationship is concluded incorrectly when in fact there is a lurking or hidden variable unaccounted for. One commonly cited example is say you find an increase of death by drownings and ice cream sales. It would be incorrect to infer that eating more ice cream causes more drownings, or vice versa. The lurking variable that can explain both is hot weather (i.e., people eat more ice cream and go swimming more to cool down). A spurious correlation is incorrectly inferring the extent of how related two variables are (not necessarily a cause/effect relation, but something used often in statistics). Here is a website that illustrates quite ridiculous correlations (a pet project of a graduate student), emphasizing that correlation is not causation.

I just had a question on my homework that im still doing so heres what i wrote
Explanation:
A plant cell has chloroplast so that it can make its own food while the bacterial cell does not as the bacterial cell is too small and the chloroplast wont fit. Bacteria cells have flagella so that it can move while plants don't as plants don't move.They both have a cell wall but a bacterias cell wall isn't made from cellulose.The bacterial cell doesn't have its genetic information inside a nucleus it is just in a single loop inside the cytoplasm.The plant cell has a vacuole while the bacterial cell doesn't.The bacterial cell has a slime capsule around the cell, outside of the cell wall. The plant cell is much bigger that the bacterial cell.Plant cells are eukaryotic while Bacterial cells are prokaryotic.Bacterial cells are single celled living organisms while plant cells aren't and they make up a plant.
