Some people worry that the increasing number of cell phones will cause cancer
because of the energy of the radio waves they emit. Cell phones are a new technology
that only recently became widely used. And because cancer takes years to develop, the
amount of risk is not yet known.
K
Research this issue, and summarize what's known so far. In your summary, include
information about the energy of radio waves. Be sure to only use credible sources.
Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?
Answer:
No.
Explanation:
No, the increasing number of cell phones will not the cause of cancer because it emits low intensity of radio waves. Radiations such as x-rays, gamma rays, alpha particles, beta particles, and neutrons are responsible for causing damage to the cell and the main cause of cancer. High intensity of radio waves heats up the cells not causing cancer disease so we can conclude that the increasing number of cell phones will not cause cancer disease in humans.

penguin
А
bat
alligator
human
extinct structures
O sequential structures
analogous structures
homologous structures
Answer: Homologous structures.
Explanation: The bones labeled A have similar structural arrangement in all the organisms but perform different functions in each organism
The bones labeled as A are known as homologous structures. Therefore, option D is correct.
What are homologous organs?Homologous organs are those present in several creatures that share a common ancestor and fundamental structure but differ in the roles they perform. The man's forelimbs, a cat's forelimbs, a whale's flippers, and a bat's wings are all examples of homologous organs.
Homologies are characteristics shared by two or more species and derived from their common ancestor. For instance, our common ancestor who lived more than 300 Mya ago left us with both the human five-fingered hand and the lizard's five-toed foot.
The forelimbs of penguins, bats, alligators, and humans are examples of homologous organs. Therefore, option D is correct.

Hereditary information is passed from one generation to the next. Which two processes are responsible for the passage of hereditary information from generation to generation in mammals, birds, reptiles, fishand other animals?
A.Meiosis and fertilization B. Mitosis and fertilization C. Mitosis and Meiosis
D. Asexual reproduction and sexual reproduction
Answer: c
Explanation:
Meiosis and fertilization, two processes are responsible for the passage of hereditary information from generation to generation in mammals, birds, reptiles, fish and other animals.
What is meiosis and why is it important?Meiosis occurs in chromosomes which allows the production of haploid germ cells necessary for seˣual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.
Fertilization restores the diploid number of chromosomes, that is 46 in human being. It provides stimulus for the ovum to complete its maturation.

The distribution of phenotypes in a species can change when changing environmental conditions cause selection to occur. Which of the following best describes evidence that would indicate directional selection is occurring?
A shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype
A shift toward equal distribution of all phenotype frequencies, including intermediate and extreme phenotypes
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes
An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes
Answer:
One of the extreme phenotypes has the highest fitness. The bell curve shifts towards the more fit phenotype.
Explanation:
It's not the exact same as yours but this is the right answer.
The following best describes evidence that would indicate directional selection is occurring is a shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype.
What is directional selection?
Directional selection. In populace genetics, directional choice is a style of herbal choice wherein an intense phenotype is desired over different phenotypes, inflicting the allele frequency to shift over the years withinside the course of that phenotype.
As there the Directional selection is occurring and causing the A shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype.

it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
5:Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. ... These forces of inertia and gravity have to be perfectly balanced for an orbit to happen.
6;Gravity is the force that keeps planets in orbit around the Sun.
