Answer:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted.
Explanation:
Answer:
If a raise in body temperature (stimulus) is detected (receptor), a signal will cause the brain to maintain homeostasis (response). Once the body temperature returns to normal, negative feedback will cause the response to end. This sequence of stimulus-receptor-signal-response is used throughout the body to maintain homeostasis.

CELLS: Choose three membrane-bound organelles. Describe them below.
Include their shape, location, and a detailed description of their function.
Answer:Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Explanation:
Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. Eukaryotes also have a golgi apparatus that packages and distributes proteins. Mitochondria are the power house of the cell and provide the cell with energy.

Look at the ecological pyramid here.
Which organism would you expect to find at level C?
Answer:
The correct answer should be C. Rabbit
Explanation:
the algae and daisy are what we call producers, so they belong on the bottom of the pyramid (level D.)
the rabbit belongs on level C, because it is the primary consumer
and lastly, the cougar belongs on level B/A because it is the tertiary/secondary consumer

On which continent were fossils of both Glossopteris and Lystrosaurus discovered?
Australia
South America
Antarctica
North America
Answer:
C. Antarctica.
Explanation:
A Glossopteris typically refers to the largest and well known rank in the classification of seed ferns known as Glossopteridales.
Also, Lystrosaurus refers to the herbivorous rank in the classification of dicynodont therapsids typically originating from the late Permian and early Triassic epochs heavily built animals.
The continent on which fossils of both Glossopteris and Lystrosaurus were discovered is Antarctica.
Fossils are the remains of ancient life forms, which are preserved by natural processes. The fossils can be imprints, shells, and skeletons.
The fossils of Glossopteris and Lystrosaurus were discovered in Antarctica.
Glossopteris is one of the largest and best-known fossils of the seed ferns. The fossil of Glossopteris is important as it shows the evidence in the Permian period that ended 250 million years ago. The fossil of Glossopteris was discovered in Antarctica.
Lystrosaurus is an extinct genus that lived in the Permian and Early Triassic periods. It is a genus of herbivorous dicynodont therapsids. The fossils of Lystrosaurus were found in Antarctica and India.
Thus, the correct answer is Option C.

If the endoplasmic reticulars were removed from the cell, which organelle would not be able to function properly, and why?
1. Mitochondria, because they rely on the ER as an energy source
2.Ribosomes, because they receive proteins made by the ER
3.Golgi apparatus, because n packages proteins received from the ER
4.Cytoplasm, because it relies on the ER for structural support
Answer:
3.Golgi apparatus, because n packages proteins received from the ER
Explanation:
1. Mitochondria, because they rely on the ER as an energy source - this is false. The mitochondria are the energy-producing organelles in the cell. They do not rely on the ER for energy
2.Ribosomes, because they receive proteins made by the ER - this is false, the ribosomes are the protein synthesis factories of the cell. Some of them are even attached to the ER
3.Golgi apparatus, because n packages proteins received from the ER - this is true. The ER is involved in folding and modifying proteins, which are passed to the Golgi for further modification and transport.
4.Cytoplasm, because it relies on the ER for structural support - this is false, structural support is provided by the cytoskeleton
Answer:
C. Golgi apparatus
Explanation:

Explanation:
MARK AS BRAINLISTBrain cells, which depend on glucose for energy, use the glucose transporter GLUT3, which has a Km of 1.5mM. Liver cells, which store glucose (as glycogen) after a meal and release glucose between meals, use the glucose transporter GLUT2, which has a Km of 15mM. Calculate the rate (as a % of Vmax) of glucose uptake in brain cells and in liver cells at circulated glucose concentrations of 3mM (starvation), 5 mM (normal levels), and 7mM (after a carbohydrate-rich meal). Use this rearranged M-M equation.
Answer:
Explanation:
Given that:
The brain cell which uses glucose transporter GLUT3 Km = 1.5 mM
The liver cell which stores glucose GLUT2 Km = 15 mM
The objective is to calculate the rate (as % of Vmax) of glucose uptake in brain cells and liver cells under starvation conditions.
Using the M-M equation i.e Michaelis- Menten equation;
[tex]Rate = \dfrac{V_{max}* [S]}{[S]+K_m}[/tex]
By rearrangement
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[S]}{[S]+K_m}[/tex]
where;
[tex]V_{max}[/tex] = maximum velocity of a reaction
Thus; the rate as a % of Vmax of glucose uptake in brain cells is calculated as:
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[3 \ mM]}{[3 \ mM]+1.5 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}= \dfrac{3 \ mM}{4.5 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}=0.667[/tex]
[tex]\dfrac{Rate}{V_{max}}=66.7 \%[/tex]
the rate as a % of Vmax of glucose uptake in liver cells is calculated as:
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[3 \ mM]}{[3 \ mM]+15 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}= \dfrac{3 \ mM}{18 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}=0.166[/tex]
[tex]\dfrac{Rate}{V_{max}}=17 \%[/tex]
Thus, the uptake is larger brain cells due to the fact that the brain cells GLUT3 have higher tendency to attract glucose.
