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❤️✨

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

How much force would a shot putter need to make a 5.5 kg shot accelerate at 8 meters per so one squared
Answer:
44 N
Explanation:
Force applied can be calculated using the formula as follows;
F = m.a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
According to the information provided in this question, mass of shot put = 5.5kg, acceleration = 8m/s². Hence;
F = m × a
F = 5.5 × 8
F = 44 Newtons
The force needed by the shot putter is 44N.
What is the function of the nucleus within a cell?
Answer:
It is responsible for protein synthesis, cell division, growth and differentiation.
Answer:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.
What scientist used radioactive bacteriophages to prove DNA is the
hereditary material passed from one generation to the next?
Answer:
Alfred Hershey and Martha Chase
Explanation:
In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.

Speciation, which leads to diversity among species through natural
selection, occurs when
Once similar species are no longer able to mate and produce fertile
offspring
Organisms develop characteristics that mimic traits of a completely
different species.
Species experience change within their lineage and develop new
characteristics.
Species interact with other species in an ecosystem and develop
similar traits to each other.
Answer:
Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.
is being left handed dominant or recessive
Answer:
recessive
Explanation:
Some scientists have reported that handedness is due to a single gene with right handedness dominant and left handedness recessive.

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.
