Answer:

Ecosystems are influenced by both biotic and abiotic factors. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.

The utilization of resources by the living organisms which are biotic factors influence the abiotic factors, which are the resources.

The term biotic factors means the factors of components of the ecosystem which are living. Therefore it can be said that all living organisms present on earth are biotic components.

Examples of biotic factors are plants, animals, human beings, decomposers, yeast, insects, etc. All of these factors or biotic components interact with each other for the development of new generations. That means reproducing new organisms to maintain the food chain.

The components of the ecosystem that are non-living are termed abiotic factors. They play a very important role in the maintenance of ecosystems. The interaction of the biotic and abiotic factors is important for the stability of the ecosystem.

Some examples of abiotic factors are air, weather, water, temperature, humidity, altitude, pH, level of soil, types of soil and more, water flow rate, water depth, etc.

Therefore, the use of water and land by living organisms are some of the many examples by which biotic factors affect abiotic factors.

d. to inform readers of the reasons why the Grimms collected their tales

Explanation:

To inform readers of the reasons why the Grimms collected their tales is the Grimm Brothers Saved the Fairy Tale,” Jack Zipes What is the author’s purpose for writing the essay. Hence, option D is correct.

The Grimm Brothers developed a system for gathering and documenting folktales. Thus, folklore studies got their start. The Grimm Brothers firmly felt that natural forms of culture are linguistic and grounded in history, which is the core theme of this extract.

It also makes reference to this, making it one of the suitable choices. They thereby preserved the mythical tale. Since the Grimm Brothers believed that old literature was the most natural and pure kind of culture and that new writing was artificial, it is clear from "Fairy Tale" why they focused on old German epics, tales, and literature rather than modern literature. Informing the reader about these causes is the text's main goal.

Thus, option D is correct.

Answer:

400

Explanation:

Scientists tagged 80 hitch. When they capture 100 hitch, 20 are tagged. In order to estimate the population of hitch, we can assume that this proportion is consistent.

This means for every 20 tagged hitch, there are 80 untagged. We know there are 80 tagged total, so we need to multiply 20 by 4 to get it to 80. To keep the proportion equal we also need to multiply the untagged hitch.

[tex]\frac{20}{80}[/tex] * [tex]\frac{4}{4}[/tex] = [tex]\frac{80}{320}[/tex]

Still following the proportion, we have 80 tagged hitch and 320 untagged hitch. 80 + 320 = 400 hitch total.

Answer: This is called sodium

Explanation: 11 protons, 11 electrons.

This  electrically neutral atom has 11 protons, 12 neutrons, and 11 electrons .

The number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

The mass number or atomic mass is the combined number of protons and neutrons in a nucleus, so it's protons and neutrons.

According to the question

Electrically neutral atom has an atomic number = 11

Electrically neutral atom has an atomic mass =  23

Now,

 the number of protons = number of electrons in the neutral atom =  atomic number.

Therefore,

The atom has proton =  11

The atom has electron =  11

As, atomic mass is the combined number of protons and neutrons in a nucleus

Therefore,

The atom has neutrons = 23 - 11 = 12

Hence, This atom has 11 protons, 12 neutrons, and 11 electrons .

Explanation:

Sodium channels may be defined as the integral membrane proteins which  forms the ion channels. It conducts the sodium ions through the cell's plasma membrane.

These channels are said to be located in the chromosome 2 of the human a well as mouse species. Sodium channels functions to mediate the fast depolarization and it conduct the electrical impulses throughout the nerves,  heart and the muscles.

The sodium channel opens when a threshold is reached at -50mV to -55 mV which causes the rapid opening of the voltage-gated sodium channels.

Explanation:

Two or more atoms held together with bonds make up a molecule. Thus option a is not a true statement.

A covalent bond is defined as  a chemical bond that includes the sharing of electron pair between atoms.

The pair of electrons are know as bonding pairs and the stable balance of attractive and repulsive forces between atoms.

The properties of covalent bond are mentioned below:

The covalent compounds have low melting points and boiling points.

The covalent compounds do not contain electricity.

The covalent compounds are  having lower enthalpies of vaporization and fusion.

The covalent compounds are easily catches fire and are more flammable than ionic compounds.

One of the cellular functions is making food/creating energy. Plant cells do this the best as they have chloroplasts that can turn sunlight, water, and carbon dioxide into glucose and oxygen via photosynthesis. This glucose is then turned into usable energy when it is transported to the mitochondria where it is turned with oxygen into carbon dioxide and ATP via cellular respiration. The ATP is taken around the cell and distributed to where it is needed via the Golgi apparatus.

NASA is now more accurate and precise with the Martian landing because they improved the interplanetary navigation that significantly tightened the eclipse between the period from 1997 to 2008.

Martian landing may also be called a Mars landing which illustrates a landing of a spacecraft on the surface of Mars. It is initiated when the spacecraft reaches the top of the Martian atmosphere, traveling nearly 12,500 miles per hour.

The landing on Mars seems difficult for all space organizations but NASA's Perseverance rover makes this possible in order to touch down the most challenging terrain on Mars that has been ever targeted.

Apart from this, the landing of NASA's Pathfinder and Pheonix also have remarkable success in the landing. Also, NASA has well-developed technologies in the field of research with good experience and talent.

Answer:

C.

Explanation:

On the punnet square, with genotype BB, you'd be highly likely to have brown eyes unless the person with blue eyes has a dominant blue eye genotype.

A person with brown eyes has children with a person with blue eyes. If all the children are brown-eyed, that means the genotype of the parents is BB. So, the correct option is C.

A square diagram is used to predict the genotype and thus the phenotype of the offspring when the genotype of the parents is known.

In a punnet square, the gametes formed from the genotype of one parent are written across the top row and gametes formed from the genotypes of another parent are written across the left corner.

The gametes are then crossed with each other to predict the genotype and thus the phenotype of offspring.

If one parent is brown-eyed, their genotype could be either BB or Bb. If the other parent is blue-eyed, their genotype is bb.

Now if all their children are brown-eyed. The genotype of the brown-eyed parent would be BB.

If the genotype of the brown-eyed parent was Bb, there would be two offsprings with genotype Bb and two offsprings with the genotype bb.

Therefore, the correct option is C
