Why is it important for gametes to go through meiosis
Answer: Because Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occ Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.ur, as it results in the formation of gametes (sperm and eggs). Hope this helps have a awesome day/night❤️✨

What's cycle works together with the carbon cycle
Answer: The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms

Katie and her sister have entirely different features and traits. Katie has blonde hair and brown eyes, but her sister has red hair and blue eyes. What causes these variations in traits such as hair color,eye color,and height? A. Competition b. Offspring c.Alleles d. Fitness
Answer:
c.Alleles
Explanation:
Genes are the hereditable units that transmit the information needed to specify traits (such as hair or eyes color), from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.
Each chromosome carries specific genes that code for specific proteins that have specific functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But not all chromosomes carry the same gene sequences. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but in different alternatives.
Alleles are the different alternatives in which a gene might appear. By the process of natural mutation, a gene might change into two or more alternative forms that are called alleles. These alternative forms codify for the same trait expressing different phenotypes.
In the exposed example, alleles are responsible for the different phenotypes expressed by the girls. The alternative forms of the genes -the alleles- that codify or hair color and for eyes color, express either red or blonde hair, and either blue or brown eyes.
The final genotype and phenotype depend on the gametes that merge to form the zygote, and hence the new organism.

Put the phases of cell division (sex cells ) in order there are 12
Answer:
Prophase I, prometaphase, metaphase I, anaphase I, telophase I, and cytokinesis, interphase, prophase II, prometaphase II, metaphase II, anaphase II, telophase II, and cytokinesis.
Explanation:
Prophase I, prometaphase, metaphase I, anaphase I, telophase I, and cytokinesis, interphase, prophase II, prometaphase II, metaphase II, anaphase II, telophase II, and cytokinesis are the 12 phases of cell division that occurs in the sex cells of human body. These double phases allow the sex cells to produce four daughter cells from a single parent cell but the chromosomes number is half in each daughter cell.

Would collecting the resources that go into bread have long-term or short-term effects on the environment? Explain your answer.
Answer:
a short term effect. In their life cycle analysis, the researchers found that a loaf of bread emits about a half-kilo of carbon dioxide. Forty-three percent of bread's greenhouse gas emissions can be attributed to the fertilizers used to grow wheat
It is a short term effect. In their life cycle analysis, it has been observed that a loaf of bread emits about a half-kilo of carbon dioxide.
What's the Environmental Impact of a Loaf of Bread?The life cycle of a loaf o bread is started from growing, harvesting, and transporting to producing flour, shipping to a bakery, baking loaves and packaging them.
In the life cycle it has been found that per loaf of bread about a half-kilo of carbon dioxide is emitted where nearly 43% of bread’s greenhouse gas emissions can be used in the fertilizers for wheat cultivation.
Two-thirds of the emissions come from actual fertilizer production.
we are unaware of the environmental impacts of this products mainly concerned with human health or animal welfare.
It was found that each loaf production is associated with global warming as a result more amount of fertilizer applied in order to increase their wheat harvest.

How do you think Nucleic Acids and Proteins work together in the body? Why are they both important to humans?
Explanation:
protein is the element responsible for building up of cells and the nucleic acid is embedded in the cell, so protein builds the whole cell including the nucleic acids.. the nucleic acid is also packed by histones which is a proteinous structure. both are important because, in the cell all organelles require protein for their growth and likewise the encoding of the genetic information carrier
