By the transfer of energy into a container of magnetic marbles the speed changes because of kinetic energy produced by the shaking of container gently. This will lead to phase changes.

All the phase changes in a system are accompanied by the change in the energy of a system. These include transfer of kinetic energy to a system. Changes from a more-ordered state to a less-ordered state are endothermic reactions. Changes from a less-ordered state to a more-ordered state are always exothermic reactions.

A phase change in a system takes place when a matter changes from one state to another state. These changes occur when sufficient amount of energy is supplied to the system or lost from the system. Phase changes also occur when the pressure on the system is changed.

Answer:

Describe the characteristics of life

Answer:

C

Explanation:

The genes contain codes that specify proteins, which produce traits.

Genes contain codes that specify proteins, which produce traits best describes how genes are able to produce a organism's traits.

Genes are segments of DNA that contain the instructions for making proteins, which are complex molecules that perform a wide variety of functions in the body. Proteins are made up of chains of amino acids, and the specific sequence of these amino acids is determined by the code contained in a gene. Different versions of a gene, called alleles, can produce different sequences of amino acids and therefore different proteins, which can lead to different traits in an organism.

Genes are found in the nucleus of cells, and the process of making proteins begins when a gene is transcribed into a molecule called RNA. This RNA molecule exits the nucleus and goes to ribosomes, which are the site of protein synthesis. At the ribosomes, the RNA molecule serves as a template for the synthesis of a protein, with the specific sequence of amino acids being determined by the code contained in the RNA molecule. The protein is then folded into its characteristic shape, which allows it to perform its specific function in the body.

Answer:

The general chemical equation for photosynthesis is

6CO2 +6 H20    →    C6H1206 + 602,

Where CO2 is carbon dioxide, H20 is water, C6H12O6 is glucose, and O2 as oxygen a byproduct.

the process begins with the splitting of water molecules-Photolysis.

2H20  +2 NADP + 8 Photons → NADPH + 2H+2 O. Photons is sunlight that splits the water molecules.

Cellular respiration  is the reverse of the process which is the

C6H1206 +6 O2 → 6H20 +6 CO2 +ATPs.

ATPs is the chief product, while C02 is the byproduct.

C. Iron

Explanation:

Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core's iron-nickel alloys is simply the elements' chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.

Answer:

enzymes loose their form in both unsuitable ph and temprature.

Explanation:

at very high tempratures enzyme molecules denatures due to high speed movements, at low tempratures enzymes works too slow to be useful enough.

low ph solotions contain lot of H+  and high ph solutions have few H+ , and the number of these H+ ions have polar effects on enzymes.  some Enzymes like pepsin works perfect in acidic environment ( ph=2)  while others might work at  high ph  or average ph( like Trypsin  works well at ph=7).

Answer:

option A.

Explanation:

That's because Science mainly deals with the study of the structure and behaviour of the physical and natural world through observation and experiments.

Answer: experimentation and then conversion of experiments into theories

Observations lead to form hypothesis and then deduction which are proved statistically by experiments

Answer:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

Explanation:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

1. Plants need light for it growth and development. By studying photosynthesis and chlorophyll one can  recognizes two factors: measure of light and development of a plant.  

The adjustment in light influences the development of a plant. Both the two factors are measurable.  

Cause-Independent Variable: measure of light  

Impact Dependent Variable: development of plant  

2. Plants have stems that become upward and roots that become descending. Become familiar with geotropism.  

Answer:

The rose experiment is not a specific experiment but refers to a general example used to explain the concept of variables in an experiment. In this example, let's say we want to study the effect of fertilizer on the growth of roses.

The independent variable in this experiment is the fertilizer. It is the variable that is manipulated or changed by the experimenter. In other words, the experimenter decides how much fertilizer to apply to each group of roses.

The dependent variable in this experiment is the growth of the roses. It is the variable that is being measured and affected by the independent variable. In this case, the experimenter measures the height, number of leaves, and number of flowers for each group of roses, and this data is used to determine if the fertilizer had any effect on the growth of the roses.

Therefore, in the rose experiment, the independent variable is the amount of fertilizer applied to each group of roses, and the dependent variable is the growth of the roses, measured by their height, number of leaves, and number of flowers.

Answer:

Explanation:

In carbon cycle, carbon is just being recycled from one thing to other. For example, here we can see that green plants are part of carbon cycle because they go through photosynthesis, a process through with plants take in Carbon dioxide. The carbon is then used to make molecules such as carbohydrates and proteins, and are part of structural support to plant cells as well. Now when this organism (the organism could be an animal or plant) dies, the bacteria decomposes the organic matter (the dead body) and through respiration the carbon dioxide is released back into the environment.

Another way carbon recycles is that animals, plants, and microorganisms all respire (breathe out) CO2 thus carbon dioxide is added to the environment.

Answer:

Hi.. Ok lets start with animals.....Animals give out carbon dioxide during the breathing process and obtain oxygen.The carbon dioxide given out by the animals is obtained by green plants which use it on addition to chlorophyll water and light energy to make their own food.When animals die they decompose to form micro organisms...The micro organisms add nutrients to the soil thus promoting the growth of plants.I think it is the foodchain

Explanation:

Respiration is a process that animals and plants undergo to create energy to grow, move and sustain life.

The equation for cellular respiration is:

glucose + oxygen —> ATP + carbon dioxide + water

The organisms use glucose from food and oxygen to create ATP (useable energy), carbon dioxide and water.

Therefore, the answer is B. Carbon dioxide and water. Glucose and oxygen are not the end results, they are used to make the end results.

Answer:

B. water and carbon dioxide
