A. Gases are more dense in the thermosphere and absorb energy easily.
B. Sunlight is reflected by the abundant gases, oxygen and nitrogen, in the mesosphere.
C. The abundance of hydrogen gas causes explosions, sending heat into the stratosphere.
D. Ultraviolet radiation is absorbed, and fewer air molecules cause the thermosphere to heat quickly.
Answer:
d
Explanation:
suns ultraviolet rays are absorbed in the thermosphere
The contributing factors cause the thermosphere to be warmer than the mesosphere is ultraviolet radiation is absorbed, and fewer air molecules cause the thermosphere to heat quickly.
What are the effects of ultraviolet radiation?The experiment that ultraviolet light made plants grow more slowly is the experiment most likely has greater reliability in which the experiment repeated several times and each time found that plants grow slightly slower with ultraviolet rays because the experiment was repeated with the same.
The main effect of ultraviolet light on plant growth is during photosynthetic active radiation under high level, UV -B light increases the net plant photosynthesis in several plant species.
Higher production of dangerous radiation can be induced under both UV-B and high PAR in young and old plant leaves.When UV light is obtained by plants resins production increases and plant become richer in smelling and better in tasting.Due to increase in resin production the plant is protected from pests and diseases.
Therefore, The contributing factors cause the thermosphere to be warmer than the mesosphere is ultraviolet radiation is absorbed, and fewer air molecules cause the thermosphere to heat quickly.

Are the seasons (summer or winter) the same in the Northern and Southern Hemispheres
at the same time? When it is summer in the Northern Hemisphere, what season is it in the
Southern Hemisphere?
Answer: No they don't occur at the same time
Summertime in the northern hemisphere happens when it is winter in the southern hemisphere, and vice versa.
The tilt of the earth causes the seasons. The northern hemisphere's summertime means that the northern part of the earth gets more sunlight compared to the southern half, so the southern half experiences winter.
With the tilt held at the same angle, the earth revolves to another point in space, so that the northern hemisphere receives less sunlight and the southern hemisphere gets more. So the seasons swap.
Answer: Winter
Explanation: The tilt of the Earth determines the seasons for the Northern and Southern Hemisphere. When the Northern Hemisphere tilts toward the Sun, it experiences summer. At the same time, the Southern Hemisphere tilts away from the Sun. It experiences winter.
You have been studying the lysosomal enzyme cathepsin D in mammalian cells. To look at the localization of the enzyme, you incorporate 32 P into the cells over a long period of time and collect fractions of the cell lysate corresponding to various organelles. Much to your surprise, you find cathepsin D was isolated in the ER fraction, and it contains 32 positive sugar side chains. However, when you pass this enzyme through an affinity chromatography column containing mannose-6-phosphate receptor conjugated to resin, the enzyme passes straight through. However, your cousin calls you up and tell you that she modified your cell line. She claims that she deleted your endogenous cathepsin D gene and transfected a plasmid containing a cathepsin D gene with a Lys-Asp-Glu-Leu (KDEL) sequence on the C-terminus.a) Why is the lysosomal enzyme found in the ER fraction rather than in the lysosomal fraction?b) Explain why the modified enzyme does not bind to the mannose-6-phosphate receptor.
Answer:
Explanation:
1.
Cathepsin is involved in programmed cell death, it is a lysosomal enzyme and the reason it is found in the ER fraction instead of the lysosomal fraction is because of its c terminal KDEL sequence. this sequence ia a retrieval for protein and causes a backward movement of protein back to endoplasmic reticulum. that is why cathepsin seems to have localised in ER instead of the lysosomal fraction
2 It does not bind to mannose-6-phosohate receptor because this glycosylation process does not occur in the E.R but in Golgi bodies. because of the KDEL sequence this glycosylation of cathepsin would not occur and cathepsin would go through affinity column without any form of binding to receptor.If cathepsin can get to the Golgi then glycolysation with Mannose6phospate can occur.

This woman is riding a bicycle down a hill at a constant speed and in a straight line. Which change will increase the speed of the bicycle?
A. An added force of 20 N to the side of the hill B. Added forces of 30 N up the hill and 20 N down the hill
C. Added forces of 30 N up the hill and 30 N down the hill
D. An added force of 20 N down the hill
An added force of 20 N down the hill will increase the speed of the bicycle, stronger gravity is applied to things with higher masses, hence option D is correct.
What condition if a bicycle down a hill at a constant speed?A force that unites things. You stay on the ground thanks to the Earth's gravity, which also causes things to fall. Everyone and everything is affected by gravity.
Gravity is the force that pulls the cyclist down toward the ground. Riding the bike ahead on a completely level road encounters very little resistance from the effects of gravity.
Cyclist gains speed even when they are not pedaling because the potential energy produced by a hill's height is converted into an equivalent increase in kinetic energy.
Therefore, an added force of 20 N down the hill is correct.

Answer:
A. Cell theory.
Explanation:
The image above shows salamander skin cells as viewed under a microscope. The activity occurring inside the rectangle best supports a scientific theory known as cell theory with respect to cell division.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell theory states that cell is the basic unit of life, all living organisms are made up of one or more cells and they typically arise from existing cells i.e pre-existing cells give rise to new ones through the process of cell division.
From the image of the salamander's skin cell, we can see that it comprises of many cells and are these look very much alike, meaning they are from pre-existing cells.

What is the importance of carbon?
The most common chemical element present on our Earth is carbon. It has the symbol C and an atomic number of 6. The carbon atom is a member of the fourteenth group present on the periodic table.
The word carbon is derived from the Latin word 'carbo', which means coal. Carbon is also the 15th most abundant element that is present in the crust of the Earth. On the earth, carbon is the fourth most abundant element ranked after hydrogen, helium, and oxygen.
Carbon atoms, when bonded together in different ways, are called as allotropes of carbon. Diamond, graphite, and amorphous carbon are the three allotropes of carbon.
They have different properties. Graphite is one of the softest known substances while diamond is the hardest known substance.

What is the benefit of diversity in a gene pool?
increased chance of migration.
increased chance of equilibrium.
increased chance of extinction.
increased chance of survival.
Answer:
Increased Chances of Survival
Explanation:
Genetic diversity we could say as Variation in a gene pool and it serves as a way for populations to adapt to changing environments, So if there is any environmental change, With more variation it more likely that some individuals will have variation of allele in them that suits the change so they will have brighter chances of surviving.
An increased chance of survival is the benefit of diversity in a gene pool.
Increased Adaptability: A broad gene pool produces a population with a wider range of genetic features and variants. Due to this diversity, there is a greater chance that an individual may have favorable qualities that will allow them to adapt to shifting environmental factors like temperature, resource availability, or the prevalence of diseases. Individuals with genetic variants that are advantageous in the altered environment are more likely to survive and pass on their genes to succeeding generations.
Better Resilience: A diversified gene pool acts as a defense against potential dangers and difficulties. A population with a diverse range of genetic variations is more likely to have some members who are immune to or resistant to particular illnesses, predators, or other stressors.
Hence, an increased chance of survival is the benefit of diversity in a gene pool.
