Which of the following is true about the products formed during photosynthesis?
They have the same mass as the mass of reactants.
They are the same set of compounds as the reactants.
They have more mass than the mass of reactants.
They are chemically the same as the reactants.

Answers

From the principle of mass conservation in a chemical process, the total mass of the reactants should be the same as the total mass of the products. So, the best answer here would be the first statement.

This is entirely theoretical as photosynthesis is neither a completely efficient process nor does it take place in an isolated system.

The second statement is incorrect since the products of photosynthesis are glucose and oxygen gas, which are completely different compounds from the water and carbon dioxide reactants.

The third statement is incorrect not only because it contradicts the principle of mass conservation, but because—if anything—mass is lost in the course of an inefficient chemical process like photosynthesis in the form of energy wasted as heat.

The last statement is incorrect for the same reason as the second statement is incorrect; the products are completely different substances from the reactants. For example, one of the products—glucose—can undergo combustion. One of the reactants, water, cannot combust.

An example of a greenhouse gas is
A. oxygen

B. carbon dioxide

C. nitrogen

by the data if...

A. traits independently assorted in
approximately a 9:3:3:1 ratio.

B. the traits for white fur and red eyes were
always inherited together.

C. all the F1 offspring had the same phenotype.

Answers

Answer: B

the traits for white fur and red eyes were always inherited together.

Explanation:

The hypothesis would not have been supported by the data if the traits for white fur and red eyes were always inherited together by the law of independent Assortment.

What is law of independent Assortment?The law of independent assortment selects alleles of two extra genes into gametes independently of each other.The allele acquired for one gene is unrelated to the allele obtained for another.Mendel's experiment constantly shown that the progeny's distinctive combinations are always unique from their parents'.He formulated the Law of Independent Assortment on this premise.

So we can conclude that as the qualities for white fur and red eyes are not usually inherited together, we may deduce that the two features are regulated by distinct genes and are independently shown in the person, as stated by the law of independent Assortment.

Which statements about tsunamis are true?
They are powerful ocean waves.
They are less destructive than typical wind-caused waves.
Earthquakes can stop them from causing flooding.
Underwater landslides can cause them.
Coastal areas are safe from them.

Answers

Answer:

they are powerful ocean waves and Underwater landslides can cause them.

Explanation:

Typical wind-cause waves aren't destructive, earthquakes make them too, coastal areas are more in danger then other areas so it's those two.

The true statements about tsunamis are, that they are powerful ocean waves, and underwater landslides can cause them.

What do you mean by Tsunamis?

Tsunamis may be defined as the giant oceanic waves under the sea that are caused either by an earthquake or a volcanic eruption.

An earthquake is a resulting factor for tsunamis which are more destructive than typical wind-caused waves.

The coastal areas are more reckless from tsunamis as compared to the middle area.

Therefore, the true statements about tsunamis are, that they are powerful ocean waves, and underwater landslides can cause them.

Answers

Answer: i believe it is not all solar energy is used for photosynthesis

Explanation:

The following is not true concerning the flow of energy through an ecosystem: "Not all solar energy is used for photosynthesis," which is in Option C, as most of the solar energy that reaches the earth is captured by plants through photosynthesis.

What is the energy flow through ecosystems?

Energy flows through ecosystems in a one-way direction, from the sun to producers (such as plants) and then to consumers (such as animals). The energy that drives this flow is primarily provided by the sun, which emits solar radiation that is absorbed by plants and other photosynthetic organisms. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose (a sugar) and oxygen. This process captures some of the solar energy and stores it in the chemical bonds of glucose, which can then be used as a source of energy by the plant itself and by other organisms that consume the plant.

Hence, the following is not true concerning the flow of energy through an ecosystem: "Not all solar energy is used for photosynthesis," which is in Option C.
