Hello!
Im beginning year 11 this year and I recently did really bad in my Mocks! I really need some help and advice for all of my subjects because I truly dont know how to revise effectively and because I keep Procrastinating!
Any advice would be appreciated or if u have links to videos and helpful websites I would appreciate it
Here are my results :

Thank u!
Answer:
I would prefer you to make a schedule in a day whenever you have time like if you're studying 5 hours a day then do maths for two hours and after that you have three hours left then take one hour for each subject like 1hr for Chemistry , 1hr for History and 1hr for Spanish so that you can study atleast 4 subjects each day. But remember that everyday you have to do maths for 2hrs and after that you can randomly change the subjects like if you have completed 1 chapter from history then you can study physics. I didn't sent you a link or website but it's just a simple advice from me for being a topper. So I hope it will help you

A statement in the introduction read, “All other factors remained the same between the two groups.” Make a list of factors that must remain constant in the experiment.
The factors that must remain the same in an experiment are known as control variables.
In order to conduct a proper experiment, there must be 3 kinds of variables. These are:
Dependent variableIndependent variableControl variableA dependent variable is a variable that the experiment seeks to observe, this variable is expected to change in value throughout the experiment and depends on other variables. An independent variable is one that the researcher changes throughout the experiment in order to see what effect it will have on the dependent variable.
The variables referred to in the question are control variables. Control variables are the factors that must remain constant in an experiment. This is to ensure that when we measure a change in the dependent variable, we know to attribute it to the correct cause of the change. The presence of control variables helps to ensure a valid experiment and limits the influence of other factors on the outcome.

How does hydrogen peroxide get into cells?
Answer:
when a cell creates hydrogen peroxide, it stores it inside the cell's specialized organelles, called peroxisomes, which contain hydrogen peroxide-busting catalase.
Explanation:
Hydrogen peroxide gets into the cell with the help of an enzyme called peroxide dismutase, which significantly catalyzes the process of dismutation of superoxide radicals in order to synthesize H2O2.
What is Hydrogen peroxide?Hydrogen peroxide may be defined as a liquid chemical that typically contains hydrogen and oxygen and is generally utilized for bleaching and as an antiseptic.
Hydrogen peroxide is consistently produced in the cell and then stored in the organelle known as the peroxisome. The cells then eliminate the excess amount of hydrogen peroxide (H2O2) with the action of an enzyme called catalase. And gest dissociates into the water (H2O) and molecular oxygen (O2).
Therefore, the process of production and digestion of hydrogen peroxide in the cell is well described above.

Imena is teaching her younger brother how to build a fire. As the fire sparks and starts to burn the kindling and wood in the fireplace, her
brother asks if the fire is alive because it is moving and growing. Imena tells her brother that the fire is not a living thing, and her brother asks
what makes something alive. What response does Imena give her brother?

For something to be alive, it has to have essential characteristics. Some non-living elements share some of these characteristics with living things, but not all of them. That is what distinguishes one from the other.
The characteristics that all living things have are:
organization; sensitivity; growth; reproduction; homeostasis; and metabolism.
As regards organization, the minimum unit of life is the cell. For something to be a living thing, it has to be a cell or have multiple cells. They have organelles and organize to perform different actions.
The following characteristic is sensitivity, which means that the thing has to react to a stimulus by giving a response.
Living things grow. In other words, they increase in size thanks to the elements that they take from the exterior and process them taking what they need to grow. To do so, they use metabolism.
Metabolism is the combination of catabolism( the elements that the organism destroys) and anabolism( the elements that the organism builds). Metabolism is also essential for homeostasis. These are the different reactions that an organism has to have a balance.
The last essential characteristic is reproduction. Living things have to reproduce themselves, there are different methods, and they depend on the type of living thing that they are.
In conclusion, fire is not a living thing because it does not have cells that can have metabolism, sensitivity, homeostasis, and it can not reproduce itself.
A living thing has six main characteristics:
organization sensitivitygrowthreproduction homeostasis metabolismEven though the fire seems like a living thing because it is consuming wood, making noises, and moving, as many living things do, it is not alive because it does not have cells. As it does not have cells, it can not have homeostasis, react to stimuli, or grow as cells do. It might look like a living thing, but it is not since it does not have the six characteristics that every living thing has.

1.If keystone species are removed, it can destroy the balance of the ecosystem
2.There can be more than one keystone species within an ecosystem.
3.Keystone species have very little importance to the balance of an ecosystem.
4.One example of keystone species in the ecosystems stem case food web are
bees because they pollinate the plants.
For characteristic features of key stone species, option 1, 2 and 4 are correct.
What are keystone species ?The presence of the species whether plant or animal in an ecosystem largely influence on a given environment called as keystone species.
It affect the habitat of all living organisms, so that the ecosystem would become functionless in absence of keystone species.
On of the best example is prey-predator relationship.
Some important environmental influence of keystone species are, it affect organism's physical appearance.
There is an impact of parasites, diseases on prey and host population, act as a mutualist, absence of key stone species leads to domino effect.
For example in absence of carnivore, number of herbivores increased, hence the environment cannot support the infinite number of herbivore population.

Which of the following best explains why Mars' and Venus' surface temperatures vary, despite both planets having atmospheres that contain mostly carbon dioxide?(1 point)
Venus has a surface of high mountains which absorb heat.
Mars has a surface of red rocks and sand which reflect heat.
Venus has a thick atmosphere which blocks heat from the surface.
Mars has a thin atmosphere that cannot hold much heat.
Mars and Venus are the planets of the solar system and vary in their temperatures. Mars has a thin atmosphere that cannot much amount of heat. Thus, option D is correct.
What is the atmosphere of Mars?Mars has been the fourth planet of the solar system that is also called the red planet due to its red appearance. It has more amount of carbon dioxide than oxygen gas. It comprises various gases and has a thin atmosphere.
The thin atmosphere of Mars unlike Venus cannot hold the heat and transmits it back to space. Venus has a thick atmosphere that traps heat and results in an increased surface temperature. The atmospheric particle of Mars cannot retain heat and hence vary in temperature.
Therefore, option D. Mars has a lower temperature than Venus due to its thin atmosphere.
