What is force?Force is defined as an outside force that has the potential to alter how a body is moving or resting. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. The idea of a force encompasses both living and non-living things. The body can change its size, shape, and direction when force is applied. As we discovered in a previous session, forces are significant because they induce modifications to motion.
Net force is defined as all of the forces pulling on a thing combined. The net force, which is a single force, replaces the original forces' influence on the particle's motion. The top 5 words that are similar to "net force" in terms of this word similarity engine are resultant force, force, acceleration, physics, and rotation.
Thus, the surface is the student not able to move the box is D.

Answer:Lipid Acids
Explanation:
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.
Answers
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.

A) Euglenozoans are eukaryotic organisms that belong to the Kingdom Protista. They are either free-living or parasitic in nature. They have no cell wall in their structure but instead possess a pellicle.
B) Diatoms are photosynthetic algae that belong to the division-Bacillariophyta. The ability to photosynthesize makes them a primary producer in an ecosystem. Their cell wall is made up of silica, which is unique to their group of algae. They also produce oils to maintain buoyancy.
C) Brown algae belong to the division- Phaeophyta. They exhibit alternation of generations in their life cycle where they produce both motile zoospores and sperm.
D) Apicomplexans are organisms such as plasmodium etc that belong to the phylum- Apicomplexa. Most of them are pathogenic, with some affecting humans. They lack cell wall but have a flat vesicle called ALVEOLI.
E) Green algae belong to the division Chlorophyta. They are photosynthetic organisms and exists as unicellular or colonial organisms. They have flagellated for locomotion.

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.
Answers
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.

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
Answers
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.

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?
Answers
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.
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.
Answers
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.
