What does the author want readers to imagine as they begin reading? Why? As you read these words, electricity is zinging through your brain, voracious killers are coursing through your veins and corrosive chemicals bubble from your head to your toes. In fact, your entire body is like an electrical company, chemical factory, transportation grid, communications network, detoxification facility, hospital and battlefield all rolled into one. The workers that drive these activities are your cells.
Answer:
The author wants the reader to think of a highly dynamic system, with movement, effectiveness and productivity.
Explanation:
As we can see in the text presented above, the author shows the human body as a highly dynamic and movement system that allows the correct functioning of all body functions. This makes the reader think of a highly dynamic factory that works in agility so that all its products are produced quickly and with great efficiency. The dynamics that the author presents becomes more evident when he says that this system is full of workers, who are the cells that regulate all work.

Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6,022 yellow and 2,001 green (8,023 total). Which of the following statements correctly describes the relationship of the allele for green soods to the allele for yellow seeds? A. The green allele is dominant to the yellow allele B. The two alleles exhibit incomplete dominance C. The green alicle is recessive to the yellow allele D. The two alleles are codominant
Answer:
C. The green allele is recessive to the yellow allele
Explanation:
Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.
Describe how the lizard population is changing
Answer:
Each time lizards colonized an island, they evolved into many of the same forms. .Other lizards adapted to life among the thin branches lower down on the trees, evolving short legs that help them hug their narrow perches. Still other lizards adapted to living in grass and shrubs, evolving long tails and slender trunks.Lizards are low on the food chain. Providing protection from their natural predators ensures their continued existence. Plant bushy perennials, create a rock or brush pile or use man-made items like stacks of bricks or pipes.
Which of the following describes a path oxygen might follow as it cycles?
A. Bird exhales. → Oxygen combines with hydrogen to produce rain.
Oxygen is taken in through a plant's roots.
B. Plant releases oxygen as a byproduct of photosynthesis. →
Oxygen molecules diffuse through the atmosphere.
> Bird
inhales.
C. Oxygen percolates through the soil. → Oxygen enters the ocean
and evaporates. → Bird inhales.
D. Bird exhales. → Oxygen molecules diffuse through the oceans. →
Plant takes oxygen in for photosynthesis.
SUBNITI
The plants releases oxygen as a byproduct of photosynthesis. this oxygen molecules diffuse through the atmosphere which are inhaled by birds. The correct option is B.
What is photosynthesis?Photosynthesis is the process of making their own food by plants using carbon dioxide and water in the presence of sunlight and chlorophyll.
During photosynthesis, plants release oxygen as a byproduct which diffuses in the atmosphere and get inhaled by the organisms.
Photosynthesis' principal role is to transform sunlight into chemical energy and then hold that chemical energy for later use. This process powers the majority of the planet's living systems.
Photosynthesis is the process by which water and carbon dioxide are converted into glucose and oxygen. The plant consumes glucose as food and produces oxygen as a waste product.
Cellular respiration is the process by which glucose and oxygen are converted into water and carbon dioxide. Water and carbon dioxide are byproducts of the process, and ATP is the energy that is produced.
Thus, the correct option is B.

what is photosynthesis
Answer:
please tell me you know, my hands are literally shaking at how easy this question is
Explanation:
the answer is photosynthesis is a way for plants to make oxygen
still not enough information? they convert carbon-dioxide and water into oxygen and sugar, so they eat the sugar making their own food, put plants are living if they eat sugar. so they also have cellular respiration from mitochindria (photosynthesis is from chloroplasts and chrolophyll inside the chloroplast) and plants BREATH OUT SOME CARBON-DIOXIDE and produce more Oxygen than carbon-dioxide, thus providing the earth with Oxygen

When a piece of paper or wood is burned, you are left with ashes that seem to weigh less than the paper or wood before it was burned. Yet when a substance is burned, it is oxidized and therefore must weigh more than it did before it was burned. Explain what happened to the “missing” weight.
It just got blowed or you can say get mixed in the air around you. You can see tiny pieces of ash while buring paper or wood. And that's exactly your answer.
Answer:
The ashes of the wood or paper either got blown around in the wind because of the ashes being so small and weightless, or they went into the air around you.

What is DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Moreover, DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes.
Hence, DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases.

Identify the statement that describes the imperfection of natural selection. Identify the statement that describes the imperfection of natural selection. Natural selection has not had sufficient time to create the optimal design in each case but will do so given enough time. Natural selection is generally limited to modifying structures that were present in previous generations and in previous species. In many cases, phenotype is not merely determined by genotype but by the environment as well. Though we may not consider the fit between the current skeletal arrangements and their functions excellent, we should not doubt that natural selection ultimately produces the best design.
Answer:
Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.
