Planets that orbit the sun is a gas giant, terrestrial, or dwarf planet.
Answer:
Terrestrial i think:)
Explanation:
A solar system is made up of a star and the planets that orbit it. Our solar system’s four inner planets—Mercury, Venus, Earth, and Mars—are closest to the sun. They are called terrestrial planets, and are largely composed of rock and metal. The four outer planets—Jupiter, Saturn, Uranus, and Neptune—are gas giants.
it's known that only 9 planets orbit the Sun. There have been many solar system objects that have been discovered recently, but none of them have been classified as planets.
Gas dwarf A low-mass planet composed primarily of hydrogen and helium.
Gas giant A massive planet composed primarily of hydrogen and helium.

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.

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.

Fireflies emit light. The production of light by an organism is called bioluminescence. To generate visible light, cells in a firefly's tail produce thousands of luciferase enzymes. Luciferase binds to a chemical called luciferin. Once bound, the luciferase enzyme speeds up a chemical reaction that combines an oxygen molecule and luciferin to produce oxyluciferin. This reaction requires energy and releases light. Which of the following best describes how the luciferase enzyme speeds up the chemical reaction? F Luciferase increases the amount of time the light is visible. G Luciferase decreases the amount of energy required for the reaction to start. H Luciferase increases the number of sites on luciferin that must bind to oxygen. J Luciferase decreases the temperature of the environment inside the body of the firefly.

Luciferase binds to a chemical called luciferin. Once bound, the luciferase enzyme speeds up a chemical reaction that combines an oxygen molecule and luciferin to produce oxyluciferin. This reaction requires energy and releases light. Which of the following best describes how the luciferase enzyme speeds up the chemical reaction?
Explanation:
b
The description that best describes how the luciferase enzyme speeds up the chemical reaction is - Luciferase decreases the amount of energy required for the reaction to start.
Fireflies generate a chemical reaction that allows their body to emit light, inside their body. This light generation is called bioluminescence. This process involves various steps:
Oxygen binds with calcium, luciferin chemical with ATP to make oxyluciferin.In the body of fireflies, there is the production of an enzyme called luciferase.This chemical reaction takes place in presence of luciferase that speeds up this reaction by decreasing the activation energy of the reaction.At the end of the reaction body of fireflies light up.Thus, the correct answer is - Luciferase decreases the amount of energy required for the reaction to start.

Why do you think so many people are ignorant on the topic of overpopulation and it's effects? Please answer in one paragraph (: thanks
Answer: Human overpopulation is among the most pressing environmental issues, silently aggravating the forces behind global warming, environmental pollution, habitat loss, the sixth mass extinction, intensive farming practices and the consumption of finite natural resources.
Answer:
I think they are ignorant because they don't understand what overpopulation can do to the world. Meaning overpopulation can cause less jobs for people. Less food to go around.

Brain 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.

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
