Can someone please help me out?!

Biology
1 answer:
Dmitry [639]3 years ago
6 0

Answer:

1. higher

2. Na + (Sodium)

3. Ca 2+ (Calcium)

4. 30mM

5. 20 mM of sodium (Na 2+) ions left over

6. K+ (Potassium)

Explanation:

1. The graph shows that potassium ions (K+) inside the cells (denoted by the gray bars) are at a concentration of approx 150mM. The concentration outside the cells (the black bars) is approx 10mM. Therefore, the concentration K+ inside the cells is much higher than the concentration outside the cell

2. The concentration of different ions outside the cell are marked by the black bars. The highest concentration of any of the black bars is approximately 130 mM (i.e. the largest black bar), which you can see from the graph is the concentration of sodium ions (Na+) outside the cell.

3. The concentration of different ions inside the cell are marked with gray bars. The lowest concentration of any of the grey bars (i.e. the smallest gray bar) is around 5 mM, which you can see from the graph is the concentration of calcium ions (Ca2+)

4. The concentration of Mg2+ ions inside the cell is represented with the gray bar. Looking at the graph, the gray bar reaches a concentration just over half way between the 0 and 50 mM markers, suggesting the concentration is approximately 30 mM.

5. There is approximately 20 mM Na2+ inside the cell, and 130 mM outside the cell, adding up to 150 mM in total. There is approximately 10mM of sodium ions inside the cell, and approximately 120 mM outside the cell, amounting to 130 mM total. This means there is about 20 mM of sodium (Na 2+) ions left over

6. We can tell by looking that ithe biggest differences between outside and inside the cell is either sodium ions, potassium ions or chlorine ions.

Approximate ion concentrations are listed:

  • Na ions inside = 20 mM, Na ions outside = 130 mM. Diff = 110 mM
  • <u>K ions inside = 150 mM, K ions outside = 10mM. Difference = 140 mM</u>
  • Ca ions inside = 5 mM, Ca ions outside = 10mM. Difference = 5 mM
  • Mg ions inside = 30 mM, Mg ions outisde = 2 mM. Difference = 28 mM
  • HCO3 ions inside = 25 mM, HCO3 ions outside = 15 mM. Diff = 10 mM
  • Cl ions inside = 10 mM, Cl ions outside = 120 mM. Difference = 110 mM

The biggest difference between inside and outside is potassium ions, K+

What is cyclin dependent kinase?​
Bezzdna [24]

Answer:

please mark as brainliest answer as it will also give you 3 points

Explanation:

Cyclin-dependent kinases (CDKs) are the families of protein kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells.[1] They are present in all known eukaryotes, and their regulatory function in the cell cycle has been evolutionarily conserved. In fact, yeast cells can proliferate normally when their CDK gene has been replaced with the homologous human gene.[1][2] CDKs are relatively small proteins, with molecular weights ranging from 34 to 40 kDa, and contain little more than the kinase domain.[1] By definition, a CDK binds a regulatory protein called a cyclin. Without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is an active kinase but its activity can be typically further modulated by phosphorylation and other binding proteins, like p27. CDKs phosphorylate their substrates on serines and threonines, so they are serine-threonine kinases.[1] The consensus sequence for the phosphorylation site in the amino acid sequence of a CDK substrate is [S/T*]PX[K/R], where S/T* is the phosphorylated serine or threonine, P is proline, X is any amino acid, K is lysine, and R is arginine.[1]

Which of the following statements best describes proactive interference? 
Wewaii [24]
The correct option is A.
Proactive interference refers to the tendency  of the knowledge that one had learned previously to prevent one from subsequent learning. Thus, proactive interference is the difficulty that comes with learning new things due to the stuffs that one had learned before. For instance, an individual may find it difficult to learn Spanish because he has previously learn German.<span />

The _____ is the serous membrane that covers the abdominal organs.
lina2011 [118]
The abdominal cavity is lined by peritoneum. It is a membrane that covers the inner layer of the cavity and also the organs inside. The membrane on the inner wall is parietal Thperitonium and the membrane that lines the organ is called visceral peritoneum.  This helps in fixation and support of abdominal organs.
