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.

The proper function of the stomates on the leaf (and therefore, the function of water and CO2 movement) is influenced most by which element

Answers

Answer:

Sunlight.

Explanation:

Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.

Answers

Answer:

1. binary fission

2.s phase

3.cytokinesis

4 spindle

5.exit from cell cycle

Cell cycle is essential for the cell to divide and grow. The correct answers are 1. Binary fission, 2. S-phase, 3. Cytokinesis, 4. Spindle fibers, 5. Exits from the cell cycle.

1. Binary fission: The parent cell divides into two brand-new daughter cells. The genetic material is split and duplicated into two pieces. Here, the DNA of each daughter cell is duplicated.

2. S-phase: DNA replication and a large portion of DNA repair activities take place in cells during the S phase, which is situated between the G1 and G2 phases of the cell cycle.

3. A cell splits into two daughter cells by physically dividing its cytoplasm through a process called cytokinesis.

4. Spindle fibers: When a cell divides during mitosis and meiosis, spindle fibers are the filaments that make up the mitotic spindle. During nuclear division, they play a major role in transporting and sorting the chromosomes.

5. G0 phase: G0 phase cells do not actively prepare to divide. When cells leave the cell cycle, they enter a quiescent (inactive) state. Some cells briefly enter G0 before the start of G1 is signaled by an outside source.

Therefore, the correct answer is c) binary fission, b) S-phase, c)cytokinesis, d) spindle fibers and e) exit from cell cycle.

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.

This resource is needed by most other countries. However, these countries dont have supplies of this resource. Should Country X keep the resource for its own use? Or should Country X share its supply by selling the resource to countries that need it? How should a fair price for the resource be determined? Who should set this price, Country Xs government or the private companies that invest in the resource?Petroleum, commonly called crude oil, is a natural resource. Like coal and natural gas, it is a fossil fuel. Fossil fuels form from the remains of organisms that lived millions of years ago. They are non-renewable, which means that Earths supply is limited.Petroleum is found in underground deposits. It is removed and processed in refineries. Many products are made from petroleum. Fuels such as jet fuel and gasoline power cars, trucks, and planes. Fuel oil is used for heating buildings and producing electricity. Roads are paved with asphalt, a petroleum product. Plastics and chemicals made from petroleum are used in everyday life.Much of the worlds petroleum comes from the Middle East. Other large producers are Venezuela, Canada, Russia, and the United States. In 1960, Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela got together to discuss the role of petroleum production in a global marketplace. They founded a group to coordinate and combine petroleum policies.The Organization of the Petroleum Exporting Countries (OPEC)The group that these five countries started is called the Organization of the Petroleum Exporting Countries (OPEC). Since 1960, OPEC has played a role in controlling the global market for oil. As oil has become more important in world trade, OPECs role has become even more important. Today, the group has grown to 14 member countries. Each member has an equal vote in making decisions. Because Saudi Arabia exports more oil than any other member country, it serves as the informal group leader.OPEC has three main goals, although it has not been effective in achieving them. It wants to regulate an efficient and stable worldwide supply of petroleum. It wants to set prices that will provide a steady income for petroleum producers. And it wants to set fair profits for companies that invest money in the petroleum industry.Regulating the Supply of Petroleum The global oil market has been affected by political events in many parts of the world. Uprisings and wars have disrupted the supply of oil. When supply is disrupted, prices rise. The economies of oil-producing countries soar. OPEC has stabilized the price of crude oil by regulating how much oil each country can produce. When production decreases, prices rise. When production increases, prices decrease.Setting Fair Prices Demand, supply, and price are interconnected. If the global demand for oil is stable, OPEC regulates oil prices by controlling the supply. It assigns a quota to each member country. Each country is not allowed to produce more or less oil than its quota. Countries that are not OPEC members can produce and export as much or as little oil as they want. They can set their own prices according to demand. However, these non-member countries must compete with OPEC members if they want to export their oil.Setting Profits for Investing Companies Each member country in OPEC needs a certain oil price in order to balance its budget. Thinking that the price of oil would remain high, many oil companies began huge oil projects in the early twenty-first century. They invested fortunes in developing new oil fields. But oil prices have not stayed high. Low prices have caused oil companies to delay or give up these projects. OPEC has tried to stabilize oil prices so that oil producers will invest in future production.The Future of OilIn the past few years, there has been a movement to decrease humans reliance on oil. Some people fear that the worlds supply of crude oil is running low. Scientists are worried that burning oil pollutes the atmosphere and causes climate change. Alternative energy sources such as nuclear, solar, and wind power are being developed. Will the demand for oil decrease? Will decreasing demand cause the price of oil to drop? Or will OPEC countries decrease production to match demand, causing oil prices to rise? If demand for oil falls, can OPEC continue to exist? No one knows for sure the answers to these questions. We will have to wait to see what the future reveals.
