Not sure about the answer pls help me

Answer:

Put both objects on a desk

Explanation:

The best way to use the materials to investigate the force of gravity would be to put both objects on a desk. The force of gravity can thus be obtained by measuring the distance between the objects as well as their masses.

According to Newton's law of universal gravitation, the force of gravity (F) between two objects is directly proportional to the product of their masses (m and M) and inversely proportional to the square of the distance (d) separating them.

Mathematically,

     F = G [tex]\frac{mM}{d^2}[/tex] where G is a constant.

The loss of phytoplankton is a huge problem for marine food chains, says Worm, because every creature in the ocean either eats phytoplankton or eats other organisms that depend on it.

Answer:

Explanation:

A Human cell has 46 chromosomes. (I’ll use humans to keep things simple). In sexual reproduction both humans have 23 chromosomes, in their sex cells. (Men have 23 in a sperm and women have 23 in an egg cell). These half cells merge to create 1 unique cell, that has characteristics of both male and female. The cells multiply and then a baby is born with a unique set of genes. These cause variations, and remember these variations can carry from generation to generation. As for how variations can increase a chance for survival, variations allow unique gene sets to be made, so that in case of a disease (in this case I’ll use a disease, but it could also include harsh environmental conditions), these unique gene sets may give an individual natural immunity to the disease. How can a variation decrease an organisms chance for survival? Well, s there are many ways that a unique gene set can make it difficult to survive. For example a genetic disease your family has had a history with. These diseases include, but are not limited to, cancer, diabetes, and schizophrenia.

Answer:

In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants.

The reactants and products of the light-dependent reactions of photosynthesis would be as follows:

Reactant: water, radiant energy, ADP, and NADP+

Products: oxygen gas, ATP, and NADPH

In the light reaction, radiant energy excites the electrons of chlorophyll molecules. The excitation causes the electrons to be knocked off the chlorophyll molecule and the energy of the electrons is used to convert ADP to ATP and NADP+ to NADPH.

The space left by the excited electrons is filled by electrons from water molecules with oxygen from the water molecule being released as a result.

Answer:

The correct option is;

C. 150

Explanation:

By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction

In the given chemical reaction process we have;

Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)

∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)

The mass of the product = 150 grams.

Answer:

Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.

Explanation:

A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.

The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.

    None of the other options are correct, as they involve more or the same use of fossil fuels per person.

Answer:

Cellular respiration, it is an aerobic process in which glucose is combined with oxygen and Adenosine di-phosphate (ADP) to produce carbon dioxide, water, and Adenosine tri-phosphate (ATP).

Cellular respiration takes place in double membraned organelle called mitochondrion.

Answer:

i) In terms of food production in plants, water is essential to plants as it is the evaporation of water that occurs in leaves that allows carbon dioxide to enter and to begin photosynthesis.

(ii) In terms of the shape of the plant, water is important to plants as the hydration of the cells of a plant allows the cell walls to retain their shape and thus give structure to the plant.

(iii) In terms of hydrolysis and dehydration, water is essential for plants because water is not a photosynthesis reactant or respiratory product.

Explanation:

i) Water is important in terms of making food in plants:

Water is required for the germination of seeds and as soon as growth starts water serves as a carrier in the distribution of mineral nutrients and plant food.

ii) Water is important in terms of the plant's shape:

Responsible for turgor pressure in cells (Like air in an inflated balloon, water is responsible for the fullness and firmness of plant tissue. Turgor is needed to maintain cell shape and ensure cell growth.)

iii) Water is important in terms of hydrolysis and dehydration:

During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen.

The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas.

Answer:

The dark brown mice would be more successful in a dark jungle since the darker color of their fur would make it hard for predators to spot them.

The process of natural selection, predict which mice would be more successful living in a dark jungle is de dark brown.

Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.

In this case, as it is a very dark forest, an animal with a white coat will attract more attention while an animal with a dark brown color will only be camouflaged in the environment.
