PLEASE HELP ASAP!!! GEOTROPISM

Answer:

Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.

Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.

Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

C.) Temperature and pH

Explanation:

Organ systems maintain the right temperature and pH levels to support life processes.

This is known as internal regulation or homeostasis.

Answer:

i just did the same question

Explanation:

A. Multiple organ systems working together

Explanation:

All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

Answer:

Commensalism

Explanation:

Commensalism, in biology, a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter.

B Because Cellulose is a polysaccharide consisting of linear chain of numerous linked D-glucose units whereas proteins are formed of number of amino acids linked together by peptide linkage.

Cellulose is a polysaccharide and a structural component of the plant cell. It is a carbohydrate made of many monomers linked together. Thus, B is the correct option.

Cellulose is an organic chemical that is insoluble in water and is a tough structure classified as carbohydrates. Cellulose is a structural component of plant cells.

It is made by monomer units linked by the beta-1,4 glycosidic bonds and is a biodegradable, tasteless organic compound with the chemical formula (C₆H₁₀O₅)ₙ.

It is the main component of the plant cell wall that provides support and shape due to its fibrous structure. It is made of linear chains of D-glucose units that makes the polysaccharide.

Therefore, option B. cellulose is a carbohydrate.

High air pressure usually means clear weather because stable air is sinking. The correct option would be D.

High air pressure usually causes the sky to be clear.

This is because high air pressure causes the air at the lower atmospheric level to sink down towards the earth.

This is unlike low air pressure. It brings a cloudy sky along with precipitation.

Explanation:

Excessively heat can damage the plasma membrane and disrupt subcellular structures such as membrane proteins and enzymes.

The following are the primary subcellular structures found in animal cells: The nucleus is where genetic material is stored.

Cell membranes regulate what enters and exits the cell. Mitochondria: aerobic respiration site. Ribosomes are the sites where proteins are synthesized.

Protein denaturation occurs at high temperatures and affects protein folding, bonding, and other types of behavior.

Furthermore, membrane proteins play an important role in cell function regulation. If these are disrupted, the system will be unable to maintain homeostasis, or a stable internal environment.

Heat can damage the plasma membrane and disrupt subcellular structures like membrane proteins and enzymes.

Thus, this way, retaining too much heat can be a disadvantage to an organism.

Humans are shielded from radiation by metal parts of a microwave oven. So, the correct option is C.

A microwave oven, often known as a microwave or electronic oven, is a device that uses microwaves, which are high-frequency electromagnetic waves, to cook food. A microwave oven is indeed a compact, box-shaped oven that increases food's temperature by exposing it to an electromagnetic field with a high frequency.

Water, lipids, carbohydrates, and a few other molecules absorb the microwaves, which causes their vibrations to produce heat. Hence, cooking time is significantly shortened because the heating takes place inside the food rather than warming the air around it. Metal components of a microwave oven protect people from radiation.

Therefore, the correct option is C.

I'm not sure about number 7 because nuclear energy its self is a renewable resource but what is used in nuclear powerplants is not.

Explanation:

Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.

Answer:

Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids,  and amino acids.

Explanation:

Heterotrophs are consumers; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.)  made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.

Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.

aerobic respiration:      C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

                                      glucose+ oxygen →  carbon dioxide+ water+ energy

Though tiny, the capillaries are one of the most important parts of the circulatory system because it's through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.

Answer:

B)

Explanation:

Several groups of students were comparing the processes of mitosis and meiosis. Each group came up with a different answer for how the two processes are different.  

Mitosis- growth and repair one cell division 2 genetically identical diploid cells

Meiosis- produce gametes, two cell division, 4 genetically different haploid cells

Hope this helps :)

The group that is correct regarding mitosis and meiosis is group 2 as they said that mitosis is involved in the growth and repair of cells and undergoes cell division once, while meiosis is involved in reproduction through fusion of gametes and undergoes cell division twice. The correct option is B.

Type of cell division by which a parent cell divides into two or more daughter cells when a parent cell divides into two or more daughter cells. Cell division is typically part of a larger cell cycle.

Cell division occurs in two stages namely mitosis and meiosis. When most people say cell division, they're referring to mitosis, the method by which new body cells are formed.

Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.

The group 2 is stating the same that mitosis is the division for growth and repair and is done in only once, and meiosis is the process of gamete formation and occurs twice.

Thus, the correct option is B.
