What are the benefits of fungi to the ecosystem?
Answer:
Fungis categorize as the "decomposers" of the ecosystem. Fungi break down dead food and recycle the CO2 foods inside it, whilst also releasing the nutrients of the dead matter back into the environment for the other organisms.

Causal attribution theories generally try to explain how we:
1) are influenced by others
2) predict how others will behave based on their attitudes
3) change our attitudes toward other people
4) determine the causes of others' behavior
5) relate to and interact with other people
Causal attribution theories generally try to explain how we determine the causes of the others' behavior based on personal or situational attributions.
This theory was developed by Horald Kelly in 1967, and explains how people attribute the behavior of others according to dispositional (internal) and situational (external) factors.
Dispositional factors are those based on internal characteristics, such as effort and skill. Situational factors, on the other hand, are environmental and external to the individual, such as luck and task difficulty.
Therefore, according to theory we are more likely to attribute the cause of the behavior of others to factors that most coincide with the action.

Biological Processes in lakes
Answer:
Explanation:
The aquatic environment is shaped by complex interactions among a variety of physical, chemical, and biological factors. For example, physical factors such as climate, land topography, bedrock geology, and soil type influence the amount of water flowing in streams and discharging to lakes, as well as the types of materials (chemicals and particulates) found in the water. In turn, these physical and chemical factors support a community of biological organisms unique to a water environment.
If you place yeast, sugar and water in a sealed bag and in the sun , what two things will be produced
Answer:
Explanation:
The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.
While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.

Lipids include triglycerides, phospholipids, and ____.
A. steroids
B. amino acids
C. starches
D. nucleic acids
The gonads and adrenal glands typically generate the natural steroid hormones from cholesterol. Lipids are the hormones in these forms. Thus, option A is correct.
What is the role of lipid in the body?Lipids serve as the body's energy reserve, control hormones, carry nerve signals, protect key organs, and transport nutrients that are fat-soluble.
Food fat gives texture and flavor, has a high caloric density as an energy source, and helps people feel full.
The body naturally creates hormone-like chemicals, but steroids are synthetic copies of such substances.
They go by the name corticosteroids and are distinct from the anabolic steroids used by athletes and bodybuilders.
Therefore, Lipids include triglycerides, phospholipids, and steroids.

The kidneys help to regulate the salt balance of the body. Normally, more than 99% of the sodium filtered at the ____________ is returned to the blood. Most of this sodium is reabsorbed at the ____________ .
Normally, more than 99% of the sodium filtered at the glomerulus is returned to the blood. Most of this sodium is reabsorbed at the proximal tubule.
The glomerulus are enveloped networks of capillaries found in the nephron of the kidney.The glomerulus are responsible for filtering and purifying blood plasma (such as sodium, phosphorus and potassium).The efferent arteriole emerges from each glomerulus, from which arises a network of peritubular capillaries and descending vasa rectus.Efferent fibers stimulate renin release and proximal tubular sodium reabsorption, thereby affecting renal and systemic vascular resistance.Reabsorption of the initial charge of the main solutes takes place in the proximal tubule.The reabsorption of water throughout the nephron follows the reabsorption of solutes.67% of the filtered water is reabsorbed in the proximal tubule by osmosis, with the reabsorption of sodium coupled to other solutes at this level being the generator of the osmotic gradient.Therefore, we can conclude that the sodium filtered at the glomerulus is returned to the blood. Most of this sodium is reabsorbed at the proximal tubule.

Which statement describes a social benefit of the sustainable use of land?
Sustainable farming of land can provide food to support a large global population.
Shared land use will protect habitats and increase the biodiversity of ecosystems.
Cutting down more trees will provide materials to build more affordable housing.
Companies will increase profits by dumping waste on public land.
Answer:
It would be the first one
Explanation:
I am sure it would be this because when farming, you are not harming the environment or any other ecosystems in anyway. It would also supply food for a constant growing population. Let me know if this helps!
Sustainability is defined by the maintenance of the factors. Sustainable land farming can supply food to support global inhabitants. Thus, option A is correct.
What is sustainable land use?Sustainable land use is the practice of using and managing the land effectively by the fair use and distribution of environmental resources like land so that it can be secured for future use.
It involves the indiscriminate usage of land resources with no negative effects or consequences that have rather a positive impact on the environment.
The use of farming land in a sustainable manner can ensure the growth of agricultural food in efficient amounts so that it can support the need for food for the global population.
Therefore, option A. the farming of land to support global food demand is a social benefit of sustainable land use.

explain why antibiotics are not consistently effective against infection of bacteria
Explanation:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

The new plant grows vegetatively from the cutting and will look exactly like the original plant.
Vegetative propagationCutting is a form of vegetative propagation attribute of some organisms.
Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.
Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.
Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.

The left cerebral hemisphere controls the muscles on the right side of the body and vice versa. Which pathway generalization best explains this phenomenon
Given our understanding of neuroanatomy, we can confirm that the left cerebral hemisphere controls the muscles on the right side of the body and vice versa due to the motor decussate of the cortical spinal pathway.
A decussate in regards to the nervous system is described as when the nerve fibers cross from one side of the central nervous system to the other. The decussate in question corresponds to the cortical spinal motor decussate.
The cortical spinal pathway is the nerve pathway that is in charge of muscular control and therefore is the pathway that is responsible for the phenomenon described in the question.

Which of the following materials is a good electrical conductor?
rubber

plastic
copper
Answer:
copper
Explanation:
Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance. An electric current will flow through all metals, however they still have some resistance, meaning the current needs to be pushed (by a battery) in order to keep flowing.
