Why are restricted-use land regulations more effective at reducing destructive use of forests?

They allow fossil fuel exploration.
They allow grazing of livestock.
They prevent hunting and fishing.
They protect land from human development.

Answers

Answer:

The correct answer would be D; they protect land from human development

Explanation:

The main reason why land is being destroyed is because we keep damaging it, also got it right on the test

They protect land from human development is more effective at reducing destructive use of forests. The correct option is D.

Thus, Regulations governing restricted-use land are more effective at halting the destruction of forests because they shield the area from habitation.

These laws place restrictions on how the property can be used, prohibiting actions like logging, mining, and building that could seriously damage the forest ecology.

Restrictive use laws support the preservation of the natural ecosystem, biodiversity, and general health of the forest by stopping or limiting these damaging behaviours.

Thus, They protect land from human development is more effective at reducing destructive use of forests. The correct option is D.

Why is it so important to maintain a core temperature of 37°C?

Question 2 options:

Your core temperature doesn't stay at 37°C, it will actually change and reflect the temperature outside.

Question 3 options:

The enzymes denature and the active site alters, so the substrate can't fit in there properly and chemical reactions don't happen as fast.


The enzyme changes shape, but the substrate still fits in and the chemical reaction can still take place.


The enzyme dissolves and the pieces then need to be rebuilt before they can be used again.

c should be your answer for the question

Each developing daughter cell obtains one set of chromosomes when mitosis comes to a finish. Thus, option C is correct.

What is genetic continuity of Mitosis?

According to the definition of mitosis, a cell divides into two so that each has the same amount of DNA as the original cell by dividing its nucleus and DNA.

When a single cell divides into two cells through mitosis, genetic continuity occurs.

One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.

As the cell divides through the cytokinesis process, the nuclear membranes come back. Mitosis maintains genomic stability throughout successive generations of cells in this manner.

Therefore, Each daughter cell receives half of its chromosomes from each of the parent cells

If 2x 2 + 13x – 7 = 0, then x could equal to which of the following?

Answers

Answer:3/13

Explanation:

Answer:

x = 1/2 and x = -7

Explanation:

you need to factor

multiply 2 x -7 to get -14

then find factors of -14 that add to give you 13

14 and -1 work

now rewrite the original equation but replace 13x with 14x - 1x

so 2x^2 + 14x - 1x -7 = 0

now factor by grouping

(2x^2 + 14x) (-1x - 7) = 0

factor the greatest common factor out of each group

2x(x + 7) -1(x + 7) = 0

the factors are (2x - 1) (x + 7) = 0

set each factor equal to zero and solve both for x

2x - 1 = 0                    x + 7 = 0

    +1    +1                       - 7   - 7

2x = 1                           x = -7

÷2  ÷2

x = 1/2

All of the following occur during RNA processing EXCEPT______________A) a protective cap is added on the 5' end of the pre-mRNAB) a tail of many adenine nucleotides is added to the 3' end of the mRNAC) the exons and introns are both removed from RNA

Answers

During RNA processing, a protective cap is added to the 5' end of the pre-mRNA, a tail of many adenine nucleotides is added to the 3' end, and only introns are removed. The correct option is C.

The pre-mRNA synthesized during transcription undergoes some processing before being ready for translation.  The first thing is the addition of a protective cap to the 5' end and the modification of the 3' end by the addition of a long string of adenine nucleotides.

Thereafter, the pre-mRNA is spliced to remove non-coding sequences, also known as introns. The coding sequences (exons) are joined afterwards before the mRNA is ready to be translated.

the nerve impulse is an electrical current that travels along dendrites or axons.

Answers

Answer:

i think your answer is true! :)

Explanation:

The statement: The nerve impulse is an electrical current that travels along dendrites or axons is true.

Dendrites are the branched projections of a neuron that receive signals (chemical or electrical) from other neurons or from sensory cells. They are often referred to as the input zone of the neuron, as they receive and integrate incoming signals from other neurons.

A nerve impulse is an electrical signal that travels along the dendrites or axons of a neuron. When a neuron is stimulated, it generates an electrical charge that spreads along its membrane, causing an action potential.

This electrical signal then travels along the axon of the neuron, where it can be transmitted to other neurons or to muscle cells or glands. The speed at which the nerve impulse travels can be influenced by factors such as the diameter of the axon, the presence of myelin sheaths, and the concentration of ions inside and outside of the neuron.

Therefore, the mentioned statement about the nerve impulse is true.
