Answer:

A. Designing nets that release unwanted species without harming them.

Explanation:

Over-fishing is a negative human practice that leads to the over-exploitation of aquatic ecosystems (i.e., both marine ecosystems and freshwater ecosystems). In an aquatic ecosystem, the communities of organisms coexist in a delicate balance where they are dependent on each other in the food web, providing stability to the whole ecosystem. Therefore, the over-exploitation of any aquatic species is expected to impact the whole ecosystem, thereby also having a negative impact on other fish populations.

Answer:

Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.

A healthy cell decides when to divide by sensing and receiving signals from its surrounding environment.

Answer:

D.) repressor DNA-binding site mutation

Explanation:

lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".

The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence.

This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.

Answer:

There will be 7 neutrons in a carbon isotope with an atomic mass of 13.

Explanation:

The number of protons in the carbon isotope will be the same as the atomic number, 6, so if we need an atomic mass of 13 there will be 7 neutrons, as 6+7=13.

If the atomic number of an element is 6 and its mass number is 13, there will be 7 neutrons. Therefore, the correct statement is option C.

Atomic number is the number of protons found in the nucleus of an atom of a specific chemical element. The atomic number is also equal to the number of electrons orbiting around the nucleus in a neutral atom.

Mass number is the total number of protons and neutrons found in the nucleus of an atom and is represented by the symbol A. The mass number is used to determine the atomic mass of the atom.

The atomic number of an element is the number of protons present in its nucleus, which is 6. The mass number of an element is the total number of protons and neutrons in its nucleus, which is 13. So, the number of neutrons in the nucleus can be calculated by subtraction of the atomic number from the mass number.

The formula is number of neutrons = Mass number - Atomic number.

Therefore, there are 7 neutrons in the nucleus of the given element.

Answer:

Will die?

Explanation:

Answer:

The action potential rate will be doubled

Explanation:

The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.

For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000

Log₁₀1000 = 3 since 10³ = 1000

Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:

Log₁₀100 = 2

Therefore, the action potential rate will be doubled

Chlorine has a higher electronegativity than hydrogen, but the chlorine atom's attraction for electrons is not sufficient to remove an electron from hydrogen. Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond.

Chlorine has a higher electronegativity than hydrogen, but the chlorine atom's attraction for electrons is not sufficient to remove an electron from hydrogen.

Electronegativity is defined as property of an atom of a particular chemical element which has been a property to attract the shared electrons while formation of chemical bond. Atomic number is the only factor that can affect the electronegativity of an atom.

The subatomic particle which is negatively charged and that has been move freely or bounded is known as electron. Electron is a subatomic particle that contain negative charges and proton is the subatomic particle which contain positive charge. Electron does not contain fix shape and size.

Hydrogen is known as the most lightest known element and hydrogen is present in the form of gas and the atomic number of hydrogen is 1. The burning of hydrogen with oxygen in order to form water.  Atomic number is the only factor that can affect the electronegativity of an atom.

Therefore, Chlorine has a higher electronegativity than hydrogen, but the chlorine atom's attraction for electrons is not sufficient to remove an electron from hydrogen.

Given parameters:

Speed of the bird  = 12.5m/s

Speed of the wind  = 4.5m/s

Unknown:

Speed of the bird when it flies with the wind = ?

Solution:

The speed of the bird when it flies with the wind is the sum of the speed of the bird and the speed of the wind.

  Speed of the bird with wind  = 12.5m/s + 4.5m/s  = 17m/s

Answer: The atmosphere can handle almost 700 billion tons of carbon in it. The carbon levels are increasing due to industrial revolution.

Explanation:

The overload of the emission of carbon in the atmosphere surprised me. The data was recorded and investigated for 2000 to 2100. Different parameters like ocean water and fossil fuel. The fossil fuel when burn contribute to the release of carbon monoxide and carbon dioxide gas. The oceanic water release the decomposed carbon dioxide by calcium carbonate of coral reefs and respiration of aquatic animals.

Answer:

When a single-celled organism splits into 2 new organisms it is called fission.

When a single-celled organism splits into 2 new organisms it is called fission. Therefore, option (A) is correct.

In biology, fission is the split of a single organism into two or more pieces, followed by the regeneration of those parts into new, distinct organisms that resemble the original. Cells are often the thing that undergoes fission, although the phrase may also describe how creatures, bodies, populations, or species divide into distinct sections.

Asexual reproduction in bacteria occurs via a mechanism called binary fission. A single organism splits into two separate ones during binary fission. The duplication of organelles in eukaryotes is sometimes referred to as binary fission.

Answer:

Explanation:

Answer:

Explanation:

Xylem transports and stores water and water-soluble nutrients in vascular plants.

Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.

Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.

Vascular tissues can provide support to the plants and also help in the transport of water, mineral and food. So, the correct options are A, B and C.

Vascular tissues mainly perform the function of supplying all the parts of the plant with water, minerals and food. there are two kinds of vascular tissues - xylem and phloem.

Xylem is the water-conducting vascular tissue. It conducts water from the roots of the plant to various other parts. In the xylem, the movement of water is unidirectional, which means it only conducts water from bottom to top and sometimes sideways

Phloem is the food-conducting vascular tissue of plants. It conducts water from leaves to other parts of the plant. In phloem, the movement of water is bidirectional, which means it conducts water from both directions. Xylem and phloem lie next to each other in a bundle called a vascular bundle.

Lycophytes are a group of seedless vascular plants which have a unique arrangement of their vascular tissues. In these plants, the lycophytes support the growth of plants.

Therefore, the correct options are A, B and C.
