Two students were discussing an article about a possible mission to Jupiter. Several ideas
about gravity came up during their discussion and they are listed below.

The Sun's gravity is pulling on Jupiter and keeps the planet in orbit
You would have the same weight on Jupiter as you do on Earth since
weight is a property of the object.
A rocket traveling to Jupiter would just need to travel beyond Earth's
atmosphere before the gravitational force would be zero.
The gravitational force of Jupiter keeps its moons orbiting.
IV.
Which of the statements above are true? Circle all that are correct.
Answer:
The Pull of the Planets is a 30-minute activity in which teams of children model the gravitational fields of planets on a flexible surface. Children place and move balls of different sizes and densities on a plastic sheet to develop a mental picture of how the mass of an object influences how much effect it has on the surrounding space.
This activity should be conducted after Heavyweight Champion: Jupiter!, which allows the children to discover the force of gravity in the solar system. These concepts involve more advanced science than previous activities in Jupiter's Family Secrets, and they explore more deeply the science of the Juno mission and the rich information it will return to us. Facilitators who choose to undertake this activity should have a firm grasp of the scientific basis so that misconceptions are not introduced to the children.
Explanation:
cellular respiration how cells harvest energy
Answer:
Cellular Respiration: a process able to extract a large amount of energy from food molecules. In eukaryotic cells oxygen is a required component. This metabolic process is the main reason that animals have elaborate gas exchange organs such as lungs, gills and other systems. The goal of these systems is, of course, to get access to oxygen and to get rid of carbon dioxide.

explain what a species is and how resources lead to species biodiversity.
Species are organisms which have similar characteristics and are capable
of interbreeding. A common example is we human beings.
Resources leads to species biodiversity as a result of organisms moving
from one place to another in search of food for its survival. The availability
of resources will lead to an increase in reproduction and species
biodiversity as more organisms will be present in the area.
Scarcity of resources on the other hand results to lower species biodiversity
and decreased reproduction rate.

Which planet has a dramatic greenhouse effect, no moons and acid in its' clouds? *
Options are
Mercury
Venus
Saturn
Neptune
Answer: venus
Explanation: Venus' thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

Which of these graphs represents the effect of temperature on the rate of photosynthesis? Explain your answer.
WILL MARK BRAINLIEST!!
Graph A represents the effect of temperature on the rate of photosynthesis.
Why is photosynthesis affected by temperature?Photosynthesis is a biological process that is essential to the synthesis of energy in plants and other primary producers. Light, water, and carbon dioxide combine to generate glucose molecules, which are the building blocks of energy-containing carbohydrates.
As a result, the waste product oxygen is emitted. Numerous factors affect photosynthesis, such as the amount of carbon dioxide present, the surrounding temperature, and the amount of light. It is a reaction with a rate constraint. High light intensities accelerate the rate of photosynthetic reaction because photons, or light particles, supply the energy needed for the reaction. According to the graph, the rate rises steadily as the intensity does, but at a certain point, the intensity stops having an impact and the rate of photosynthesis plateaus or becomes constant.
Beyond this point, the reaction is restricted by either the temperature or the carbon dioxide supply. For instance, at high intensities, heat or high temperatures may even harm tissues.

Answer:
It acts as a catalyst to break down harmful bacteria.
Explanation:
The bacterial cell was is made up of murein also called peptidoglycan. The active site of the enzyme lysozyme binds with the molecule of peptidoglycan attacking and breaking it. It degenerates the bacterial cell wall eventually killing the bacteria.Lysozyme mostly, works on the gram-positive bacteria as the peptidoglycan layer is present on the outer side of the cell wall unlike gram-negative where it is present in the inner side of the cell wall. Thus, acting and functioning as a catalyst that breaks down walls of bacteria, enhances innate immunity, and protects from infection.For more information:
