C. two muscles are crossing the same jointif a bacterial cell is capable of taking up foreign dna, it is said to be what?
Answer:
competent
Explanation:
The uptake of foreign DNA from the environment is known as transformation
If a bacterial cell is capable of taking up foreign DNA, it is said to be competent.
What is competent?
Transformation is the process by which bacteria can absorb foreign DNA. In DNA cloning, transformation is a crucial step. After restriction digest and ligation, it takes place and transmits freshly created plasmids to bacteria.
Bacteria are chosen on antibiotic plates after transformation. Bacteria are extraordinarily adaptable creatures, with the rare capacity to take in and replicate (or copy) foreign DNA.
They gain an evolutionary advantage from this and are better able to withstand environmental changes. Bacteria, for instance, can acquire DNA that renders them immune to antibiotics.
Therefore, the term is competent for a bacterium that is capable of taking up foreign DNA.

Photosynthesis Virtual Lab
Summarize the results and provide an explanation or reasoning for what was observed. How does light color affect the rate of photosynthesis? Why does the color of light matter?
Answer:
The lights higher on the light spectrum, like blue would have the fastest rate of photosynthesis because the energy is the highest. the green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as mich as the other colors. The color matters because the color or wavelength of light does affect photosynthesis, which is how plants can create their own food.

How can the reliability of the investigation be improved?
Answer:
You can test reliability through repetition. The more similar repeated measurements are, the more reliable the results. The reliability of single measurements is not improved through repetition, but through the design of the experiment. Implementing a method that reduces random errors will improve reliability.

Which of the following is NOT a principle of the cell theory?
Group of answer choices

Very few cells are able to reproduce.
Answer:
Very few cells are able to reproduce
Explanation:
took a test on it yesterday and got the answer correct!
Please leave 5 stars and a thanks.
Answer: Very few cells are able to reproduce.
Explanation: Only the mitochondria is the only cell to reproduce. Not many people know that and it's not a principle of the cell theory because it was never mentioned. Hence, our answer is Very few cells are able to reproduce.
A cell is grown in a medium with radioactive amino acids for five minutes. The radioactive amino acids are able to be transported into the cell and assimilated into the proteins that are being assembled. After the cells are removed from the radioactive culture, the level of radioactivity is monitored at different time points. It is found that the area of the cell with the highest radioactivity after five minutes is the ribosomes on the rough endoplasmic reticulum. As time progresses, which statement best explains where the level of radioactivity will be highest in the next five minutes?
A) The radioactivity will be highest in the mitochondria, as the proteins made by the cell will need to be modified using ATP.
Eliminate
B) The radioactivity will be highest in the nucleus as the proteins made at the ribosome will be shipped to the nucleus to replicate the DNA.
C) The radioactivity will be the highest outside of the cell because the endoplasmic reticulum transports proteins directly to and through the cell membrane.
D) The radioactivity will be highest in the Golgi apparatus, as proteins made on the rough endoplasmic reticulum are transported to the packaging center prior to leaving the cell.
Answer:
It’s D ,I got it right on USAtestprep
Explanation:
The correct option for this answer is D, which signifies that the radioactivity will be highest in the Golgi apparatus, as proteins made on the rough endoplasmic reticulum are transported to the packaging center prior to leaving the cell.
What do you mean by Radioactivity?Radioactivity may be defined as a spontaneous process that involves the emission of radiation in the form of particles or high-energy photons resulting from a nuclear reaction.
The path of protein transport determines the level of radioactivity in this experiment.
First, the radioactivity is found highest in the ribosomes of ER, then the proteins are transported to the region of the Golgi apparatus by an anograde pathway and reflect in radioactivity.
Therefore, it is well described above.

existing cells.
b. the cell theory states that all cells contain a
nucleus
c. the cell theory was established in 1665 by
Robert Hooke.
d. the cell theory says that a cell membrane
separates one cell from another.
Answer:
The cell theory asserts that all cells comes from existing cells
Explanation:
plss mark brainliest
The cell theory asserts that all cells come from existing cells. Option a si correct.
The cell theory is a fundamental principle of biology. It was first proposed in the 19th century by Theodor Schwann and Matthias Schleiden. The cell theory states that:
All living things are made up of cells.Cells are the basic unit of structure and function of all living things.All cells come from existing cells.The cell theory has been supported by many scientific observations and experiments. For example, scientists have observed that cells divide to produce new cells. They have also observed that cells from different organisms have similar structures and functions.
The cell theory is a powerful tool for understanding living things. It allows scientists to study the structure and function of cells, and to understand how cells interact with each other. The cell theory has also led to the development of new technologies, such as cell culture and genetic engineering.
The other options are incorrect. Option b is incorrect because not all cells contain a nucleus. Option c is incorrect because the cell theory was not established in 1665 by Robert Hooke. Option d is incorrect because a cell membrane does not separate one cell from another. A cell membrane surrounds each cell, but it does not separate one cell from another.
