Based on the trends you observed in the laboratory exercise, which objects would you expect to be attracted to a bar magnet? Check all that apply.

a metal hammer
a wooden ruler
a plastic car
the metal frame of your chair
the paper in your notebook
the screws and nails that hold your desk together

Answers

Answer 1

Answer:

The correct answer is - 1. a metal hammer

4. the metal frame of your chair

6. the screws and nails that hold your desk together.

Explanation:

Bar magnets are rectangular objects made up of ferromagnetic objects or substances and must carry the north and south pole ends. These objects show ferromagnetism and attract any ferromagnetic metal such as iron, steel  or ferromagnetic composite.

In the case of the same ends, for instance, the north-north pole of two magnets repulse and opposite attract to one another. From the given options the correct answer is a metal hammer, the metal frame of chair and screws and nails that hold the desk.

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.

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

Answers

Answer:

C. Y

Explanation:

The point that the kinetic energy increasing and its potential energy decreasing is Oz.

How to measure kinetic energy?

To calculate the kinetic energy of an object with mass “m” and speed “v”, we must apply the formula Ec = mv²/2, where: Ec – kinetic in joules; m – mass in kg; v – speed in m/s.

What is potential energy?

Gravitational potential energy that depends on the vertical position and mass of an object.

With this information, we can conclude that The point at which the kinetic energy increases and its potential energy decreases is Oz.

Describe how the lizard population is changing

Answers

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.

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.

Answers

Answer:

Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.

What happens to cause air to be exhaled from the lungs?
A)The rib muscles contract and move upward
B)The chest cavity expands and grows larger
C)The diaphragm relaxes and moves upward
D)The lungs contract and expand

Answers

Answer:

The answer is C.

Explanation:

When you breathe out or exhale, your diaphragm relaxes and moves up into your chest cavity. As the space in your chest cavity gets smaller, the air rich in carbon dioxide is forced out of your lungs and windpipe, and then out your nose or mouth.

answer: C: The diaphragm relaxes and moves upward

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.

Answers

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.

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

Answers

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.

All of an organism's chromosomes can be found next to its genes in the cell nucleus

Answers

Answer:

Genes are special sequences of nucleic acids found on chromosomes.

Explanation:

A single DNA molecule is a chromosome. A gene is a certain chromosome region of DNA.

All cells of the body are genetically the same, but cells are different from others because specific gene sets are expressed. Different cells, therefore express different genes, which enable them to perform a specific function.

The deoxyribonucleic (DNA) genes are segments that contain a code for a certain protein that works in one or several cell types in the body. Chromosomes are cellular structures that contain the genes of a person. Genes that are in the cellular nucleus are contained in chromosomes.
