Answer:
one of the nature given important part of our life is sun as it provides heat and light to each and every creature present in the earth which is used for cooking, growing,and and for getting vitamins like vitaminD .it generates the weather patterns and also stirs our atmosphere.thus it is quite important for human as well as for animals and plants to run their livelihood. The second one is plants as we know plants are one of the most precious gift of nature to all the living being it provides oxygen and is the the major source of food for both plants and animals.plants prevent us from the natural disasters like flood , landslide, earth quake and other natural disasters this is is quite important in Every living beings life.
Answer with Explanation:
Nature is very important for the survival of living things, including humans. We rely largely on it for almost everything. Two examples of these are the food and clothing that we get from nature. With the help of nutrients coming from plants, we are able to nourish our body and become healthy. Besides this, we can also derive fibers from plants that are needed for making clothes. These help us stay warm, thereby preventing us from getting sick.
Additional Information:
Apart from the above, "nature" plays a huge role in maintaining a person's peace of mind. For example, people go to the mountain to bathe in the forest and meditate. It helps calm the mind and reconnect with our environment.
2. How can dominance and expression of alleles explain the differences between these fraternal twins?
Answer:
Fraternal twins are from two seperate eggs.
Explanation:
The first part of the question is missing but any difference between fraternal twins can be explained by the fact that two seperate eggs are fertilized during the pregnancy so they have different genomes which leads to having different dominance of different genes and this leads to different expressions of this genes.

Identify the statement below that is NOT a principle of evolution.
O Populations evolve, individuals do not
O Negative adaptations will become more common in a population
O Variations occur naturally within a population
O Adaptations help individuals compete successfully for survival
B) negative adaptations will become more common in a population
negative adaptations will become more common in a population.
What is Evolution?According to the idea of evolution in biology, the many species of plants, animals, and other living things on Earth descended from earlier species, and their recognizable differences are the result of changes made by subsequent generations.
More than 2 million species of organisms already in existence have been recognized and documented; many more are still undiscovered, with estimates ranging from 10 million to 30 million.
The amazing variability in size, form, and mode of existence, from tiny bacteria with a diameter of less than a millionth of a millimeter to majestic sequoias with a height of 100 meters, is as astonishing as the figures.
Therefore, negative adaptations will become more common in a population.

1. A worker uses a board that is 4 m long to pry up a boulder. A small rock is used for a
fulcrum and is placed 0.5 m from the resistance end of the lever. Calculate the MA of the
I
board.
Answer:
7
Explanation:
Mechanical advantage is given by the ratio of the distance of the fulcrum from the two objects of the system.
Here the boulder is [tex]0.5\ \text{m}[/tex] from the fulcrum and the mass at the other end of the lever is [tex]4-0.5=3.5\ \text{m}[/tex] from the fulcrum.
So, mechanical advantage is given by
[tex]MA=\dfrac{3.5}{0.5}\\\Rightarrow MA=7[/tex]
So, mechanical advantage of the board is 7.
Does anybody have a presentation about Mendel's second law. Please I need it to do well.
Answer:
See the answer below
Explanation:
Mendel's second law of genetics is also known as the law of independent assortment of genes.
In this law, Mendel opined that genes are independently inherited. In other words, Mendel said that the factors that dictate the physical attributes of living organisms are inherited independently.
This means, for example, that the color of your eyes is independently inherited from the color of your skin, your skin color is independent of your hair color, etc.
Mendel was able to prove this law by performing a dihybrid cross using the pea plant.
A true-breeding plant that is dominant for round and yellow traits (RRYY) was crossed with another true-breeding plant that is recessive for wrinkled and green traits (rryy).
All the F1 offspring were round with yellow color and the cross was advanced to F2. The F2 plants segregated in the ratio of 3:1 for the round trait to wrinkled traits and also 3:1 for the yellow to green traits respectively.
The outcome was the same as carrying out a monohybrid cross for each trait independently. Hence, Mendel concluded that traits are inherited independently of each other.

What is the function of mitochondria in muscle fibers?
Answer:
During strenuous exercise, the rate of energy use in skeletal muscles can increase by more than 100-fold almost instantly. To meet this energy demand, muscle cells contain mitochondria. These organelles, commonly referred to as the cell's “power plants,” convert nutrients into the molecule ATP, which stores energy.

Which structure pumps out excess water and wastes?
Answer:
The contractile vacuole pumps out excess water and wastes.
Cells have a particular organelle that pumps out excess water and other wastes from the cell. Contractile vacuole serves this purpose.
The protozoan cell contains an organelle or subcellular structure called the Contractile Vacuole. It is a spherical, transparent, translucent, pulsating single-cell organelle. Previously, it was referred to as a pulsatile or pulsating vacuole. It is encased in a unit membrane, floats in the cytoplasm, and is filled with watery fluid. It is a vacuole that constricts and expels water from the cell, as its name suggests. It frequently stretches and shrinks. While water is expelled from the contractile vacuole as it expands, the contractile vacuole contracts, causing water to collect inside the organelle. The contractile vacuole is the protozoan unicellular organism's kidney. It shows the rhythmic systolic and diastolic movements.
Therefore, Contractile vacuole pumps out excess water & wastes.

What happens to DNA once transcription is done?
Answer: Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. ... RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Explanation:
Once transcription is completed, the newly synthesized RNA molecule called messenger RNA (mRNA), undergoes further processing and then moves on to the next step in gene expression, which is translation.
In eukaryotic cells, the mRNA molecule undergoes several modifications before it is ready to be translated into protein. These modifications include the addition of a protective cap structure at the 5' end of the mRNA, the addition of a poly-A tail at the 3' end, and the removal of non-coding regions called introns through a process called splicing. These modifications are important for the stability, transport, and efficient translation of the mRNA.
Once the mRNA is fully processed, it is transported out of the nucleus and into the cytoplasm, where it encounters ribosomes. Ribosomes are cellular structures that facilitate the process of translation.
During translation, the mRNA is read by ribosomes, and the sequence of nucleotides in the mRNA is translated into a specific sequence of amino acids, forming a protein. This process occurs in the cytoplasm and is mediated by transfer RNA (tRNA) molecules that bring the appropriate amino acids to the ribosome based on the codons present in the mRNA.
