What happens when a light wave hits a translucent object, in terms of energy?
1) some of the energy is transmitted, whilst the rest is absorbed and reflected
2) most of the energy is transmitted
3) all energy is reflected
4) all energy absorbed
Answer:
1) some of the energy is transmitted, whilst the rest is absorbed and reflected
Explanation:
"When light strikes translucent materials, only some of the light passes through them. The light does not pass directly through the materials. ... Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy."

Why do saturated fatty acids have straight structures, while unsaturated fatty acids have bent structures?
Answer:
Saturated fatty acids exhibit a linear structure while unsaturated fatty acids bend, or kink, due to double bonds within the chemical foundation.
Please mark for brainliest.
Answer:
Saturated fatty acids have a straight structure because "the bend" comes when there is a double bond on one of the bonds. This causes the fatty acids to have slight polarity and be bent.Explanation:
Scientists have developed genetically engineered plants that are pest-resistant. By adding genes to the plant's DNA, they become toxic to insects (but not to plants or animals). This means that these plants may not need to be sprayed with pesticides to ward off the insects.
Answer:
Genetically modified organisms (GMOs) have altered their genomes in different ways in order to be resistant to both biotic (e.g., insect pests) and abiotic (e.g., drought) stress conditions
Explanation:
A genetically modified organism (GMO) is any organism, i.e., plant, animal, bacterium, etc., whose DNA has been altered by genetic engineering. The GMO crops can exhibit resistance to insect pests in order to increase their agronomic yields (as well as resistance to other biotic and abiotic stresses). It is for that reason that GMO crops are widely used in many countries. A commercially available GMO crop is Bt corn, which is a genetically engineered maize that expresses proteins from the bacterium Bacillus thuringiensis (Bt), which are poisonous to several insect pest species.

Why must you avoid breathing or coughing on an agar plate?
Answer:
Explanation:
An agar plate is simply a Petri dish and it contains agar as a solid growth medium. It also contains nutrients for the culturing of microorganisms. Because of this reason, we must avoid breathing and coughing on these agar plates to avoid contaminating them. If they get contaminated we won't only see microorganism growth that we want to see for the experiment or test but also all the organisms from our body.

Relate the law of conservation of mass to photosynthesis
The Law of Conservation of Mass holds true in photosynthesis
because the number of ______________
Answer:
moles of reactants is the same as the number of moles of products
Explanation:
Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight and water using energy from the sun. It is chemically symbolized as;
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
In the reaction above, the number of moles are balanced so as to comply with law of conservation of mass.
The law of conservation of mass states that "matter is neither created nor destroyed in the course of a chemical reaction but are simply transformed from one form to another".

True or False Water moves from an area of low water concentration to an area of high water concentration.
Answer:
False
Explanation:
It is true that water moves from an area of higher water concentration to an area of lower concentration.
Based on osmotic pressure, water always moves from an area of higher concentration to that of lower concentration.
Osmosis of water and liquids is made possible across a concentration gradient. Water is driven from one place to another via concentration gradient.Which of the following statements best explains how roots aggregate soil?

A
Amount of water put into
the container B
Amount of anti-freeze
added to the water
C
Temperature at which the
mixture freezes D
Type of thermometer
used to make the
measurement
Answer:
C Temperature at which the mixture freezes
Explanation:
Measuring the temperature at which the mixture freezes provides a good way for the student to arrive at her conclusion.
The variable being tested for in this experiment is the freezing point of the water anti-freeze mixture. The dependent variable which is the freezing point is of prime concern. Amount of the antifreeze added is the independent variable. It is the cause of the phenomenon desired to be observed in the experiment.There are different kinds of measurements. Measuring which of these variables will help her arrive at a conclusion is Temperature at which the mixture freezes.
The act of Measuring the temperature at which the mixture freezes helps one to known or arrive at a conclusion. Note that the variable that is tested for in this experiment is the freezing point of the water anti-freeze mixture.The temperature at which a substance freezes is referred to as its freezing point. Freezing point is also known to be the physical property of matter.

calculate the mass of 0.35 mole of copper (||) sulfate (CuSO4).
The mass of 0.35 mole of copper (||) sulfate (CuSO4) is found to be 55.86 g.
What is the mass of any substance?The mass of any substance may be defined as a measure of the amount of matter in that particular substance. It is usually measured in grams (g) or kilograms (kg). Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it.
According to the question,
The mole of copper (||) sulfate (CuSO4) = 0.35 mole.
The molar mass of copper (||) sulfate (CuSO4) = 159.60.
∴ The mass of any substance is calculated by the given formula:
Molar mass × No. of moles.159.60 × 0.35 = 55.86 g.
Therefore, the mass of 0.35 mole of copper (||) sulfate (CuSO4) is found to be 55.86 g.
