Describe Earth's magnetic field. Include an explanation of how scientists believe it is generated. Also include two ways in which it helps people on earth.

Answers

Answer 1

Answer: The magnetic field extends from the Earth's interior out into space, where it meets the solar wind, a stream of charged particles emanating from the Sun.

Scientist believe that due to the molten liquid iron of the Earth's core, and to the fact that iron is magnetic and can create an electric current, the constant turning is what creates the magnetic field.

The sun releases high charged particles on the Earth, without the magnetic field we would experience bursts of radiation on the ground.

Answers

Answer:

Developmental progression of functional skills

Explanation:

With the passage of time, a kid not only grows physically and mentally but also in his/ her cognitive abilities to perceive and understand the happening around him. He develops a a relationship sense for peers, family members and related adults. Similarly, he also develops the ability to learn the things which are quite basic for us like taking off clothing items.

These things come under the umbrella of developmental progression for functional skills. studies have shown that a kid learns to take off clothing items before he learns to put them on. Same is the case with putting on socks, a kid can take off socks by the age of 12 months which is earlier than he learns to put them off (age of 18 months) with the assistance of any elder and independently by the age of almost 4 years.

This developmental progression helps a kid to modify his behavior and to be more independent.

Plant Cell
- Cell Wall: Provide and maintains the shapes of the cells.
- Cell Membrane: controls what goes in and out of the cell.
- Cytoplasm: the "space filler" of the cell.
- Vacuole: Storage holder of the cell.
- Lysosomes: they digest unneeded food particles,wasted cell parts + foreign invaders.
- Mitochondria: makes cell energy.
- Golgi bodies: packages proteins.
- Chloroplast: Where photosynthesis takes place.
- Chromatin: contains the hereditary material of the cell.
- Ribosomes: makes proteins for cell activities.
- Endoplasmic Reticulum: transport system of the cell.

The criteria used to determine whether something is alive includes movement, growth and

Answers

presence of protoplasm, self built organisms, self repair, reproduction and various life process like metabolism, nutrition, respiration, exchange of material, transportation, excretion and irritability.

One good way to remember this is with the acronym MRS GREN;

Movement - The organism can move in some way (plants move as they grow)
Reproduction - Creating new copies of this organism
Sensitivity - A response to a change in the environment around the organism

Growth - The ability to create new structures / cells
Respiration - The ability to break down food to get energy
Excretion - The organism creates waste which is disposed of
Nutrition - The organism has the ability to eat food

Mary and her siblings share similar hair color. Which of these cell components are most involved in determining the hair color of each sibling? *A. Gene, chromosomes, and nucleus
B. Cytoplasm, chloroplasts, and genes
C. Vacuoles, nucleus, and chromosomes
D. Chromosomes, chloroplasts, and vacuoles

Answers

The cell components that are most involved in determining the hair color of each sibling is gene, chromosomes, and nucleus. The correct option is A.

What are genes and chromosomes?

Genes are small spherical-shaped hereditary material that is present on chromosomes in a bead fashion. They contain the hereditary material of the organism. These are uncountable numbers of genes present in the chromosome.

Chromosomes are x shapes of hereditary material that are preset inside the nucleus. It is made up of DNA, genes, and proteins. Genetic characteristics of the genotype of an organism are unique because of unique genetic material, and this can be transferred to another generation from the first generation.

Therefore, the correct option is A. Gene, chromosomes, and nucleus.
