The tiny magnetic effect of atoms within a domain is due to electrons that are _____.

Answers

Answer 1
Answer:

Answer: The correct answer for the blank is-

unpaired and spinning in the same direction.            

The given question relates to the atoms of Ferromagnetic materials, which are the materials that produce magnetic effect. They have potential to form permanent magnets and they possess unpaired electrons, which spin in the same direction.

Example of ferromagnetic material- Iron.

Answer 2
Answer: unpaired and spinning in the same direction

Mendel's experiments demonstrated the law of dominance: traits are inherited as dominant and recessive alleles, and the dominant allele for a trait can mask the presence of the recessive allele. Occasionally, that law is contradicted: offspring exhibit a blend of their parents' traits. For example a red flowering plant when crossed with a white flowering plant would produce a plant with pink flowers. This type of inheritance pattern is called A) codominance. B) multiple alleles. C) incomplete dominance. Eliminate D) heterozygous dominance.

By 1863, control of most of the Mississippi River was in Union hands. To gain control of the last major port city serving as an open shipping door to the South, Grant weakened the enemy with a military campaign that lasted several months. First he isolated the port city by gaining control of the railroad, and then he began a seven-week artillery siege to force surrender.What is the port city described above?

A. Chancellorsville
B. New Orleans
C. Vicksburg
D. Appomattox

Answers

The port city that is described in the excerpt is Vicksburg, Mississippi. The goal was to starve out the south by having control of the seaports and the river. The correct answer is C.

What would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%? O The water would move out of the cell and the cell would decrease in size.

O The water would move into the cell and the cell would increase in size.

O The salt would move into the cell and the cell would increase in size.

O The salt would move out of the cell and the cell would decrease in size..​

Answers

Answer:

The water would move out of the cell and the cell would decrease in size.

Explanation:

This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.

In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size

If an animal cell with an internal salt concentration of 10% is placed in a salt solution with a concentration of 30%, the water would move out of the cell and the cell would decrease in size.

If an animal cell with an internal salt concentration of 10% is placed in a salt solution with a concentration of 30%, the water would move out of the cell due to osmosis. The higher external salt concentration draws the water out of the cell, causing the cell to shrink or decrease in size.

Compare and contrast a hypothesis and a theory

Answers

A hypothesis is proposed explanation that's made on the basis of limited evidence as a starting point for further scientific investigation.

A theory, and I suppose you're referring to the scientific theory, is
 a well-substantiated explanation for some aspect of the natural world. It's based on a large body of facts that have been repeatedly confirmed through extensive observation and experiment.
Compare and Contrast Theories and Hypotheses. A hypothesis is a possible scientific explanation of an observation or set of observations.

Wildlife is plentiful in the pineywoods. There are over 100 species of birds and many small mammals, like cottontail rabbits and squirrels.What else MUST be included in the pineywoods habitat to keep populations in balance?



A) predators, like snakes
Eliminate

B) omnivores, like raccoons
C) more producers, like plants
D) small animals, like the opossum

Answers

Answer: The correct answer is-

A) predators, like snakes.

As per the information given in the question, there is plentiful wildlife in the  pineywoods. It is inhabited by more than 100 species of birds and many small mammals such as cottontail rabbits and squirrels.

In order to keep balanced population in pineywoods habitat, it is required to include predators like snakes ( that capture and eat other organisms as source of energy such as birds, rats, and other small mammals) as they will prevent the organism from overcrowding in the habitat.

Thus, it will maintain a balanced population in the pineywoods.

Therefore, option A) is the right answer.

There have to be predators in pinewoods, or else the wildlife will exceed the carrying capacity and begin to die off.
