Light level is an important factor in aquatic ecosystems.

The physical or chemical parts of the environment that affect the organisms that are in that environment.

An aquatic ecosystem is a water-based environment. Abiotic factors are the non-living components that form the environment in which organisms subsist in a current.

The main abiotic factors in the marine environment are as; light, temperature, salinity, and hydrostatic pressure. dissolved oxygen, acidity (pH), salinity and depth.

Here Without pollution or acid rain, most lakes and streams would have a pH level of around 6.5.

Therefore Light level is an important factor in aquatic ecosystems.

Answer: D. It provides evidence of links between evolutionary species.

Explanation: The significance to scientists of finding a new, unknown fossil is that it provides evidence of links between evolutionary species.

Organisms arose as a result of these changes, and some of their remains have been preserved as fossils. An organism's type, life history, and preservation method can all be ascertained by studying a fossil. Thus, option D is correct.

They can discover when and how various animals existed millions of years ago by studying fossils. Fossils can sometimes show scientists how the Earth has changed over time.

The discovery of a new, undiscovered fossil is significant to scientists because it shows connections between evolutionary species.

Fossils with remarkably similar geometries are thought to be from the same species. It is considered that fossils with somewhat differing geometries come from a separate species. Usually, the fossil species has been researched and given a name.

Therefore, It provides evidence of links between evolutionary species.

Explanation:

el3m3nt is pure substance and is only made up of one type of atom it cabt be broken down into simpler substance

molecules form when two or more atoms form chemical bonds with eachother

The biggest difference between elements and molecules is that elements only have one TYPE of atom, while molecules have MULTIPLE types of atoms. The statement is true.

When two or more atoms are connected by a chemical bond will form a molecule.

The fundamental unit of element is  atom, which consist of a nucleus and its surrounding electrons.

There are different types of molecules like diatomic molecules where only two atoms are combined. For example carbon monoxide (CO) made of a single atom of carbon and one of oxygen.

This diatomic molecule can be homonuclear diatomic molecule, like oxygen (O2) and nitrogen (N2).

Similarly another type called polyatomic molecules have more than two atoms, for example water (H2O) and carbon dioxide (CO2).

The molecular weight of a molecule is calculated by sum of total atoms' atomic weights present in it and  represented by Avogadro's number (6.02214076 × 1023).

Answer:the answer is ammonia

Explanation:the nitrogen fixing bacteria fix the nitrogen as ammonia

Answer: C

Explanation:

When a neuron receives a stimulus, the sodium channels present in the membrane are opened, and therefore Na+ enters the cell in favour of the concentration gradient, so that the membrane potential changes to positive by means of ion exchange, producing depolarization. If this depolarization reaches a certain threshold value, an action potential is generated. The next step is the opening of the potassium channels and the inactivation of the sodium channels, so that the repolarization of the membrane takes place. The sodium channels, will return to the closed state in the hyperpolarization to continue in this state during all the rest potential achieving the action potential to return to -70 mV (repolarization).; until the arrival of a new action potential which produces the activation and opening of the sodium channels, repeating the cycle again and generating a new depolarizing action. This process is part of the synaptic transmission.

So, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. This means, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in membrane voltage where the membrane potential is more distinctly positive or negative are hyperpolarizations.

During the repolarization period after an action potential, the membrane potential is more negative than when the cell is in "rest period". In the picture, this repolarization period is about 1-2 milliseconds. So, repolarization is the time in which the membrane potential is hyperpolarized with respect to the resting potential.

In the attached figure, part C indicates this repolarization period.

[tex] \bold{ \green {Scope \: of \: Environment \: education}}[/tex]

Environmental education includes the study of various factors of the environment which affect the health of human beings. Environment comprises all the factors in our surroundings. It includes even abstract factors , which do not have weight , length and breadth. Cultural traits , social norms and values, feasts and festivals etc. are some of the examples of abstract aspects. Some of the scopes of environment education are described below:

The physical aspect included non- living things on the earth. They are soil, water , air , rocks , gases etc. Environment education gives knowledge about the status of soil , water , air , rocks , gases and other various physical components of the earth. It aims to make students aware of the effects and consequences of human activities upon these factors. It also gives knowledge to raise environment friendly attitude and behavior among the students .

The biotics factors include living plants and animals , their life mechanism , interrelationship etc. Some of the educational streams related to the biotic aspects are biology , agriculture , and forestry. They are some of the important scopes of the environment education. This branch of education helps to develop the level of knowledge , attitude and behavior regarding these factors in the students.

Environment has some of the abstract aspects too. Abstract aspects include religious , cultural , ethnic and social norms and values. Some of the educational streams dealing with this aspect are sociology , civics and anthropology. Environment education also teaches students about such abstract factors, which play vital role in the environment.

[tex] \bold{ \green{Scope \: of \: Health \: education}}[/tex]

In general , scope of health education can be understood as the areas included in health education. Health education not only communicates knowledge about body features and diseases, but also includes the matters concerned with healthy surroundings , human psychological states affecting health , public health, human anthropology , medical science and so many other things. Any three scopes of health education are as follows:

Home is the residence of all people. Home is the first school for all. A child passes the primary days of life at home. Every individual learns the basic skills if survival at home. Proper time to wake up in the morning , to start daily sanitary schedules, to eat , to practise all other health behavior are learnt at home. The child lives in community and learns many more about healthy social adjustment in the social environment. Health education aims to raise the level of knowledge , attitude , and behavior related to health and healthy life.

Children go to school for formal education and spend most of active hours of a day. They achieve several forms of health knowledge and develop healthy attitude and practise accordingly. Their heath status depends upon the environment of school , health curriculum, healthful school environment , co-curricular and extra - curricular health activities.

Community is a place where many people live with their families. People's health is determined by the several factors in the community. Health education teaches about these factors like community sanitation , drainage , health service providing organizations and health centers.

Answer:

preexisting cells present in the air can grow in sterilized nutrient broth

Explanation:

Spontaneous generation, which is the theory that life can arise from nonliving matter, has long been believed to be the way living organisms develop. However, in 1858, a French scientist called Louis Pasteur disproved the theory of spontaneous generation.

Louis Pasteur conducted an experiment to show that it is the existing microorganisms in air that causes life to grow and not the air itself. Pasteur made use of a swan-necked flask, which contained a sterilized (by boiling) broth. The swan-necked flask was designed in such a way that it would allow air to enter but trap any airborne microorganism, preventing them from reaching the broth.

Hence, if it were truly air and not existing life organisms that caused life growth, organisms should begin to grow from the broth. He conducted another experiment where be broke the neck of the flask to allow the entry of microorganisms into the sterilized broth and found out that growth of microorganisms occured on the broth.

Therefore, Pasteur, via his experiment was able to prove that preexisting cells present in the air can grow in sterilized nutrient broth if allowed entry but when there is no entry, there would be no life growth. This experiment disproved the theory of spontaneous generation.

Explanation:

Sub-cellular particles are particles smaller than the living cell and are found suspended in the cytosol (of a cell) like the nucleus, golgi complex and the mitochondria.

While acellular particles/organisms are particles that do not have a cell like the virsues, viroids and prions. They are not alive/inactive outside a living environment but become active immediately they are inside a living environment (like a cell).

Sub-cellular particles are structures that are found within a cell. These structures perform specific functions and are essential for the cell to carry out its biological processes.

Examples of sub-cellular particles include organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. These structures are composed of both proteins and lipids and are enclosed by a membrane.

Acellular particles, on the other hand, are particles that do not possess a cellular structure and are not alive. These particles are much smaller than cells and are unable to carry out any metabolic processes.

Examples of acellular particles include viruses, prions, and viroids. These particles are composed of either DNA or RNA and can replicate themselves only within a host cell. They do not have their own metabolism and rely on the host cell for replication and survival.

Answer:

The yeast die at 140° F

Explanation:

The fermentation process is caused by the living organisms called yeast feeding on the sugar in the dough. As the yeast feed on the sugar they release CO² which causes the bread to rise but once the bread in the oven reaches 140° all the yeast are killed off and the fermentation process stops.

The process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.

Fermentation may be defined as a process a chemical process by which molecules such as glucose are broken down anaerobically in the presence of yeast.

During fermentation, the yeast produces excess carbon dioxide due to which the dough of bread swells. But after the completion of fermentation when bread places in the oven or any other warmer temperature, it killed the yeast, and hence fermentation stops.

Therefore, the process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.

D) that geographically isolated groups of dogs may be selected for quite different traits, resulting in a different dog breed

Explanation:

Artificial selection is a type of selective breeding made by humans in which offspring with desired traits are selected. Modern dogs evolved by artificial selection. Dog breeding began around 30,000 years ago from selective breeding of wolves that were separated from their original population and bred to produce dogs with desired traits (especially, loss of aggressive behavior). Purebred are reproductively isolated groups of dogs originated from the same lineage (i.e., the same common ancestor for each group), that never mated with another dog breed.
