For the lac operon, when glucose is absent and lactose is present ___________ Group of answer choices cAMP-CAP is bound to the operator and the repressor is not bound to the promoter cAMP-CAP is not bound to the promoter and the repressor is bound to the operator cAMP-CAP is bound to the promoter and the repressor is not bound to the operator None of the options
Answer: cAMP-CAP is not bound to the promoter and the repressor is bound to the operator.
Explanation:
cAMP levels are going to be low because glucose is not present, so CAP is inactive and will NOT bound to the DNA.
the golgi body interacts the most with which of these
A.nucleus
B.free ribosomes
C.Nucleolus
D.endoplasmic reticulum
When it comes to the processing and classification of proteins within the cell, the endoplasmic reticulum (ER) and the Golgi apparatus (also known as the Golgi body or Golgi complex) most often interact. Therefore, the correct option is D.
Before being delivered to their final cellular locations, proteins made by ribosomes on the rough endoplasmic reticulum (RER) are folded, packaged, and sorted in the Golgi apparatus. Modification, separation, and packaging of proteins and lipids for transport inside the cell or secretion outside the cell occurs in the Golgi apparatus, which is composed of flattened membrane sacs called cisternae. It takes up proteins and lipids from the ER, modifies them, and then puts them into vesicles for distribution to various cellular compartments or to be secreted from the cell.
Therefore, the correct option is D.

Trevor is a 20-year-old male presenting with a history of fatigue, shortness of breath, gallstones, and yellowing of the skin and eyes (jaundice). An examination of his blood reveals his red blood cells have an abnormal elliptical shape which causes premature damage and rupture of the cells. Trevor is diagnosed with a genetic disease, Hereditary elliptocytosis. The disease is caused by mutations in some of the proteins of the membrane skeletal network responsible for the stability of the red blood cell. What organelle is defective in Trevor's red blood cells?
These cells are also characterized by having no nucleus, being devoid of organelles. So no organelles are missing from trevor's red cells.
What is Hereditary elliptocytosis?Hereditary spherocytosis and elliptocytosis are congenital disorders of the erythrocyte membranes that cause mild hemolytic anemia. Symptoms, usually milder in hereditary elliptocytosis, include varying degrees of
AnemiaJaundiceand Splenomegaly.Diagnosis requires demonstration of increased osmotic fragility of erythrocytes and a negative direct antiglobulin test. Rarely, patients < 45 years of age with symptomatic disease require splenectomy.
With this information, we can conclude that the red cells of Trevor do not have organelles, a fact that is not altered by their condition (Hereditary elliptocytosis).

Describe the currents that form along the equator.
The currents that form along the equator are known as equatorial currents. These currents are driven by the trade winds and the Earth's rotation, creating a unique circulation pattern in the ocean.
There are two main equatorial currents:
Equatorial Counter Current: This current flows eastward along the equator, opposing the direction of the trade winds. North Equatorial Current and South Equatorial Current: These currents flow westward on either side of the equator.The equatorial currents play a significant role in redistributing heat across the ocean and influencing climate patterns.
Thus, the equatorial currents along the equator are dynamic and essential components of the global ocean circulation system, playing a crucial role in the Earth's climate system.

Kudzu, a plant native to eastern Asia was introduced into America in 1876. In 1935, kudzu was planted along southern roadways to control soil erosion. Adding a foot of vine a day in the spring and summer, kudzu quickly grew out of control. Why can introducing a new species to an existing ecosystem often be a disaster?
A. The new species can rapidly evolve into a dangerous subspecies that cannot be destroyed.
B. The new species can harm native organisms and damage the ecosystem.
C. The new species can create excess nutrients in the soil that can damage native species.
D. The new species can eventually become extinct.
Answer:
The best answer is B.
Explanation:
Since Kudzu is a foreign plant introducing it to the United States could damage the ecosystem since the ecosystem here is not "designed" to handle the Kudzu. This could cause a chain reaction along the food web and can potentialy wipe out local organisms.

How would a scientist describe the illustrations showing the bones of a whale flipper and a bat
wing?
Vestigial structures because they will lose their function over time
Homologous structures because the structures are similar but have different functions
Analogous structures because they are similar but have different functions.
Embryonic structures because they show up before the species matures.
The bones of a whale flipper and a batwing are homo-logous structures because the structures are similar but have different functions. They have a common origin.
What are homo-logous structures?Homo-logous structures can be considered as similar structures that have the same evolutionary origin but may or not have the same function.
Homo-logous structures are always present in a common ancestor of the species that have these structures.
Conversely, analogous structures have the same function but they do not exhibit a common origin.

in what cell organelle does photosynthesis occur?cellular respiration?
Photosynthesis occurs in chloroplasts and cellular respiration occurs in mitochondria.
What do you mean by cellular respiration?Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.
Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.
