How Golgi bodies play a important role in the cell?
Answer: The Golgi body is responsible for packing up proteins and lipid molecules and exporting them outside of the cell.
Explanation: The Golgi apparatus or body is a important organelle that helps the cell transfer and pack up proteins and lipids(Fat) and sending them outside the cell.
Answer:
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.

3. PI of a protein is dependent on the number of acidic and basic amino acid residues in the protein.
Answer:
The study of proteins is important because all the genes in cellular DNA house the program or code for a unique protein structure.
Explanation:
Within the science parlance, pl is the short way to write Isoelectric Point. It is the pH (that is the acidity or basicity) of a solution at which the net charge of a protein becomes nil.
The surface, in most cases, is likely going to be negatively charged when the pH of that same solution is above the pl. When this occurs, molecules that have similar negative charges will tend to move away or be repelled.
It is useful to note that the structure of proteins comprises of 20 amino acids all of which are connected by peptide bonds.

what would it take to determine the climate has changed?
Answer:
Sea level rise is another clue that tells us Earth's climate is getting warmer. But melting ice is not the only cause of rising sea levels. As the ocean gets warmer, the water actually expands! Scientists have observed that the sea level has risen 7 inches in the last 100 years.
Explanation:
Because the hotter it get the more water in the ocean the colder less water in the ocean or it could stay the same
Which technology can be used to follow endangered animals that have been

C. Geographic information systems (GIS)
D. Unmanned aerial systems (UAS)
Answer:
I personally think that all the methods could potentailly work but I would have to go with "A" as usaully GPS's are used as they are more simple and easier to have in a collar, as radio technology is probably the number one most used by people such as scientists
How does energy change when two objects collide? Think about how potential and kinetic energy work, Explain HELP PLZz!!
As you can see, when objects collide, or bump into each other, it causes the objects' energy to move and change. Objects that have potential energy, or stored energy, are set into motion through collision, and the energy transfers into kinetic energy, the energy of an object in motion.
Answer:
If you can see, it allows objects to rotate and change as objects clash or bump against each other. By collision, objects with potential energy or stored energy are pushed into motion and energy passes into the film energy, the energy of a moving object.
Explanation:
If one strand of dna has sequence of bases. T T G C A G T G G A C T what would the matching strands sequence be
Answer:
A A C G T C A C C T G A DNI Matching strand sequence
Explanation:
DNI is composed of subunits called nucleotides. Nucleotides are subunits or monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base. The chain or sequence of nucleotides composes the polymer. Different nucleotides joined by their extremes compose the DNA and RNA. Nitrogenated bases are Adenine, Guanine, Thymine, and Cytosine.
According to the Watson and Crick model, bases get in pairs by hydrogen bridges:
For DNI complementary strands
- Adenine pairs with Thymine, A ↔ T
- Guanine pairs with Cytosine, G ↔ C
However, if we are talking about RNA complementary strands, then
- Adenine pairs with Uracile, A ↔ U
- Guanine pairs with Cytosine, G ↔ C
RNA molecule replaces Thymine for Uracile.
The matching strands sequences for the proposed strand are:
T T G C A G T G G A C T Original strand sequenceA A C G T C A C C T G A DNI Matching strand sequenceA A C G U C A C C U G A RNA Matching strand sequence

Which TWO actions could you take to make a building less likely to crumble in an earthquake
A. Make walls thinner so they bend in easily
B. Build closer to likely liquefaction regions
C. Use base isolation does line while building
D. Add brackets for vibration control
WILL GIVE BRAINLIEST ANSWER
Answer:
C and D!
Explanation:
I am 90% sure these are the answers because
A: Thinner walls = more likely to break down
and B: Liquefaction means that the ground will become less solid during earthquakes, causing the building to be severely damaged.
Thus, leaves C and D as the leftover answers! :]
Two actions that make a building less likely to crumble are;
Use base isolation does line while buildingAdd brackets for vibration controlWhat is an earth quake?The term earth quake refers to a situation in which there is a powerful shaking of the earth which could cause buildings and other structures to cave in.

Transcribe the DNA sequence into mRNA: TAC CCA AGT
PLESSE HELPPPP
Answer:
AUG GGU UCA
i think im not sure
umm im trying to figure it out tho i think its A
Explanation:
Answer:
AUG GGU UCA
Explanation:
To transcribe the sequence, we first must find the complementary sequence of the DNA sequence. To do this, we must know that "A" pairs with "T", and "G" pairs with "C". What this means is we replace A with T,G with C, and vice versa. We get ATG GGT TCA. Now all we have to do is replace all the "T"'s with U's as Thymine is replaced by Uracil in RNA. Doing this we get AUG GGU UCA, which is the answer.
Which of the karyotypes shown is from a normal female?
A
B
C
D
Answer: c
Explanation:
Females have two X chromosomes and males have an x and a Y chromosome. The Y chromosome is significantly shorter because it doesn’t carry as many genes. C is the only option that has two X chromosomes
The karyotype of a normal female is in diagram c. The correct option is c.
What is a karyotype?A karyotype is an individual's complete set of chromosomes. The phrase might refer to an image created in a lab showing a person's chromosomes separated from each individual cell and organized in numerical order.
If a person has a mutation, the karyotype can tell whether they are a man or a mulcher. This is so because a person's chromosomes are represented by a karyotype.
A 23-pair karyotype, one of which is made up of sex chromosomes that are XY for males and XX for women, is required for a person to be considered to be mutation-free.
Males have an x and a Y chromosome, while females have two X chromosomes. The Y chromosome is considerably smaller because it contains fewer genes. The only choice with two X chromosomes is C.
Therefore, the correct option is C.
