Answer:
Reduction DivisionExplanation:
Reduction division is the process that is most important for producing haploid cells during meiosis. Therefore, option (B) is correct.
What is meiosis?Meiosis is a type of cell division that occurs in sexually reproducing organisms. It involves two successive divisions (meiosis I and meiosis II) that result in the production of four daughter cells, each with half the number of chromosomes as the parent cell. This reduction in chromosome number is known as "reduction division."
Reduction division is important because it ensures that the daughter cells produced by meiosis have the correct number of chromosomes. In organisms that have a diploid number of chromosomes (such as humans, which have 46 chromosomes), the daughter cells produced by meiosis have a haploid number of chromosomes (23 chromosomes). These haploid cells can then combine with other haploid cells during fertilization to form a new diploid organism.
Independent assortment, synthesis, and crossing over are also important processes that occur during meiosis, but they do not directly produce haploid cells. Independent assortment refers to the random distribution of chromosomes to daughter cells during meiosis I. Synthesis is the process of DNA replication, which occurs prior to meiosis. Crossing over is a process that occurs during meiosis I in which chromosomes exchange genetic material, leading to genetic diversity in the daughter cells.

Multicellular organisms use mitosis for growth, development, and
A . apoptosis
B . repair
C . reproduction
D . interphase
Multicellular organisms use mitosis for growth, development, and repair and they also play the role of decomposers. Thus, option B is correct.
What is the key role of decomposers in the nitrogen cycle?Decomposer serve a key role in the nitrogen cycle primarily because they break down plant and animals waste and release nitrogen into the atmosphere.
These processes has been based on the single principle: the difference in density between the components of the mixture. They are often used together to separate heterogeneous mixtures of two types as liquid + solid and immiscible liquids. In this case we have what mixture is the sediments of stones and the water that through the sieve will separate one from the other.
Mining has a large impact on the environment because minerals are contained within the Earth. The long term effects of mining include acid drainage, erosion and dust emissions.
Therefore, Multicellular organisms use mitosis for growth, development, and repair and they also play the role of decomposers. Thus, option B is correct.

What are the two main principles of Mendelian genetics?
Answer:
The key principles of Mendelian inheritance are summed up by Mendel's three laws: the Law of Independent Assortment, Law of Dominance, and Law of Segregation
Explanation:
__________
Answer:
Mendel's observations from these experiments can be summarized in two principles: According to the principle of segregation, for any particular trait, the pair of alleles of each parent separate and only one allele passes from each parent on to an offspring. Which allele in a parent's pair of alleles is inherited is a matter of chance.

Find the density of an object that has a mass of 22.3g and a volume of 136.7cm3.
Answer:
[tex]0.1631309437 g/cm^3[/tex]
Explanation:
The formula for density is ρ[tex]=\frac{m}{V}[/tex] (where [tex]m[/tex] represents mass, and [tex]V[/tex] represents volume).
With this formula, we can calculate the density of the object:
ρ [tex]= \frac{22.3g}{136.7cm^3}[/tex]
[tex]=0.1631309437 g/cm^3[/tex]

А.organ
B.organism
C.tissue system
D.organ system
Tissue system, enables the snake to move forward by pushing against the ground while bending and curling its body. Thus, option C is correct.
What level of organization are present in snake?The body of a snake is long and slender, and it is separated into four quadrants. Head, esophagus, heart, and trachea make up the first quadrant's major structures.
The second quadrant contains the liver, stomach, and anterior, vascularized region of the lung(s).
A snake has a basic skeleton because it has no arms or legs. Hundreds of ribs extend from the base of the tail to the end of the long, flexible spine that connects the head to the backbone.
This enables the snake to move forward by pushing against the ground while bending and curling its body.
Therefore, tissue system level of organization is represented by the skeleton of the snake.
