Explanation:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.
The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. This hot added material cools down by conduction and convection of heat. .
What would happen to a plant if the chloroplasts in its cells became damaged?
(1 point)
O The plant would be unable to make protein.
O The plant would be unable to reproduce.
O The plant would not have a rigid structure.
O The plant would not make glucose and oxygen.
If the chloroplasts of the plant cell become damaged, it would not be able to make glucose and oxygen. So the correct option is D.
What are chloroplasts?Photosynthesis, the mechanism by which light energy is transformed to chemical energy and results in the generation of oxygenation and energy-rich organic molecules, takes place in the chloroplast, a structure found inside the cells of green algae and plants.
Endosymbiotic hypothesis holds that mitochondria and chloroplasts, which are energy-producing structures in eukaryotic cells, are descended from photosynthetic cyanobacteria, which are free-living near cousins of chloroplasts.
A plastid is a sort of body that is formed like a disc, an oval, or a circle and is used to synthesise and store food. Chloroplasts are one type of plastid. The green colour of chloroplasts, which derives from the existence of two pigments called chlorophyll a and chlorophyll b, sets them apart from other plastid types.
These pigments have the capacity to absorb light energy for the purpose of photosynthesis. Carotenoids are one of the additional pigments found in chloroplasts that act as accessory pigments, capturing sun energy and transferring it to chlorophyll.
Therefore the correct option is D.

Predict: Of the molecules shown on the molecules pane, which do you think are inputs (ingredients) in photosynthesis? Which do you think are outputs
Answer:
Input ingredients = water, carbon dioxide, energy from the sun
Output ingredients = glucose, oxygen
Explanation:
Photosynthesis involves the production of carbohydrates from inorganic products. The chemical equation for the process is represented below:
[tex]6CO_2 + 6H_2O + sunlight--> C_6H_1_2O_6 + 6O_2[/tex]
Water and carbon dioxide molecules combine in the presence of sunlight radiation to give glucose and oxygen molecules.
Input ingredients = water, carbon dioxide, sunlight
Output ingredients = glucose, oxygen
The molecules are shown on the molecules pane inputs (ingredients) in photosynthesis -
Inputs - H2O + CO2output - C6H1206 + O2Photosynthesis is a cellular metabolic process, regulated by enzymes to convert radiant energy to chemical energy, its inputs and outputs are the following:
Inputs: carbon dioxide and water from which organic compounds are synthesized, using the light absorbed by pigments as an energy source.Outputs: sugar and oxygen are produced in photosynthesis as a food source that is energy for the plant.Thus,

humans have hundreds of different g-protein-coupled receptors. while these receptors all have distinct amino acid sequences, they all have in common: guanine nucleotide exchange activity
What is guanine nucleotide?
Guanine nucleotide exchange factors (GEFs) are proteins or protein domains that stimulate the release of guanosine diphosphate (GDP) to enable the binding of guanosine triphosphate, hence activating monomeric GTPases (GTP). It has been demonstrated that guanine nucleotide exchange activity occurs in a number of unrelated structural domains. While some GEFs are exclusive to a particular GTPase, others can activate numerous GTPases.
Small GTPases are activated by proteins or protein domains known as guanine nucleotide exchange factors (GEFs). In intracellular signaling pathways, small GTPases function as molecular switches and have a wide range of downstream destinations. The Ras superfamily of GTPases, which is made up of the most well-known GTPases, is crucial for key cellular functions such cell division and proliferation, cytoskeletal structure, vesicle trafficking, and nuclear transport. GTPases can have their activity controlled by GEFs and the opposing GTPase activating proteins because they are active when bound to GTP and inactive when attached to GDP (GAPs)

D.

Warm, more dense molten material rises while cool, less dense material sinks creating convection currents which cause the tectonic plates to move. The correct option is A.
What is tectonic plate movement?Tectonic movements are the subsurface movement of formations caused by natural Earth forces.
Plate movement results in three types of tectonic boundaries: convergent boundaries, where plates move into one another, divergent boundaries, where plates move apart, and transform boundaries, where plates move sideways in relation to one another.
As thermal energy from the core heats the mantle, molten material rises toward the crust and begins to cool.
As the material cools, it sinks back toward the core, dragging some of the crust with it. Convection currents in the Earth's mantle move the plates and shape the continents.
Thus, the correct option is A.

a population of deer was threatened with overpopulation until cheetahs were imported. after a couple of years, there were fewer deer, but the average running speed of the deer had increased. this is an example of Predator-prey coevolution.
Overpopulation is a condition when a species have so much population that the carrying capacities of the nature starts getting exhausted.
Overpopulation is also not good for a population because it will causes depletion of the resources which will ultimately lead to the extinction of the species.
When the cheetahs are introduced in an area overpopulated with deer species, they will keep the population in check. Also, as deer have to save itself they have to increase their running speed to survive and hence evolve with same adaptation.

Explain your thinking. Describe how variations are passed on from one generation to the next.
Through gene rearrangement, genetic variation occurs from generation to generation.
What is genetic variation?
Only genetic variation—not environmental variation—can be passed on to the next generation. If two populations of the same species' phenotypes diverge to the extent that they are unable to mate and produce fruitful offspring, they may split into two separate species.
Genetic variations can result from gene variants, commonly referred to as mutations, or they can arise naturally when a cell divides, when its genetic material is naturally rearranged. Genetic alterations that alter gene activity or protein function can create many phenotypes into an organism.
