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.

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

Answers

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.

How do you think the Law of Universal Gravitation State connects why apples fall down and planets circle in orbit?

Answers

Apples are drawn to a massive object, like the earth, and fall down under a gravitational constant. On the other hand, planets revolve around a more massive object under the same premise. It’s the same idea, just one follows a linear path, and the other has a uniform circular motion path because other forces are acting on it. In other words, the planets ARE still falling, but the sun is also pulled by them so they just keep dancing.

How might the increase of volcanic eruptions affect Earth?

A. It might produce more ozone in the atmosphere


B. It might decrease temperature across Earth


C. It might increase the carbon dioxide in the atmosphere


D. It might cause the Earth’s surface to absorb more oxygen.

Answers

If enough ejecta (mainly ash) is sent into the upper atmosphere, the dust particles will block solar energy causing a decrease in temperature. This has happened in the past. Look for the year without summer caused by a volcanic eruption.

Would collecting the resources that go into bread have long-term or short-term effects on the environment? Explain your answer.

Answers

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.
