Does anybody have a presentation about Mendel's second law. Please I need it to do well.
Answers
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.

Which structure pumps out excess water and wastes?
Answers
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.

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.
Answers
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.
2. How can dominance and expression of alleles explain the differences between these fraternal twins?
Answers
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.

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.
