Answers

Answer:

They interact by the upper mantle transferring energy by conduction to the core  assisting in the softening of the rock layer which leads to radiation.

Explanation:

Convection currents coming from the core and mantel are believed to the main cause of the interaction. As these currents travel up and down the curst and mantle boundary and this creates the plates to move freely forming a conveyor belt. The core of the earth creates this convective current to rise up due to the heat and pressure. The hot molten rocks in the mantle eventually cool and the cycle of rising and sinking takes place.

Answers

Answer:

Explanation:

plants capture and store the energy they derive from light during photosynthesis in ATP molecules. ... When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).

The green plants store the food that is produced during this process as the six carbon sugar called glucose.

What is photosynthesis?

The term photosynthesis refers to the process by which green plants produce food by the use of carbon dioxide and water.

In this process, the green plants store the food that is produced during this process as the six carbon sugar called glucose.

Marine dead zones can form when nutrient run-off causes certain types of algae to grow very quickly and then die off. As dead algae decompose, oxygen is removed from the water. With less oxygen available, fish and other marine animals can die. What would be one practical way to reduce marine dead zones?

A: Add bacteria that are able to eat the fast-growing algae.

B: Harvest marine fish in dead zone areas to reduce oxygen use.

C: Pump oxygen into the water using equipment on fishing vessels.

D: Prevent fertilizer and other wastes from entering rivers and streams.

A cell removes a toxin it has produced through a chemical reaction. Which characteristic of living things is the cell demonstrating?


the ability to maintain homeostasis

the ability to maintain homeostasis

the ability to grow and develop

the ability to grow and develop

the ability to adapt and evolve

the ability to adapt and evolve

the ability to reproduce

Answers

Answer:

Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.

According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.

Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.

Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.

a. Gene theory

b. Homeostasis

B

An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.

False

False

Humans began life as a single cell because we develop from a fertilized egg cell.

Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.

No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.

Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

what are the 7 factors of classification of living things

Answers

1 Nutrition

Living things take in materials from their surroundings that they

use for growth or to provide energy. Nutrition is the process by

which organisms obtain energy and raw materials from nutrients

such as proteins, carbohydrates and fats.

2 Respiration

Respiration is the release of energy from food substances in all

living cells. Living things break down food within their cells to

release energy for carrying out the following processes.

3 Movement

All living things move. It is very obvious that a leopard moves but

what about the thorn tree it sits in? Plants too move in various

different ways. The movement may be so slow that it is very

difficult to see.

4 Excretion

All living things excrete. As a result of the many chemical

reactions occurring in cells, they have to get rid of waste products

which might poison the cells. Excretion is defined as the removal of

toxic materials, the waste products of metabolism and substances

in excess from the body of an organism.

5 Growth

Growth is seen in all living things. It involves using food to

produce new cells. The permanent increase in cell number and size

is called growth.

6 Reproduction

All living organisms have the ability to produce offspring.

refer to the other question I answered by you. 0 degrees Celsius would be frozen, 100 would be boiling hot. Since -2 is the lowest, that would be the coldest/ least amount of thermal energy. 60 degrees Celsius is the highest, so it has the most thermal energy. Again, thermal energy is just heat energy, so you just need to figure out which is hottest.
