Which type of mixture is it, if the solid settles out of the mixture over time?
O suspension
o homogenous
o colloid
solution

Answers

Answer:

Suspension

Explanation:

A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution and thus gravity is able to pull them down out of the dispersion medium (water).

If the solids settle out of the mixture over time, such a type of mixture is called suspension.

A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing.

What are the different types of mixtures?

there are mainly two types of mixtures that are:

homogeneous mixture

homogeneous mixture

A homogeneous mixture is a mixture throughout the solution in which the composition is uniform throughout the mixture.

A homogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.

Hence,  a suspension is a heterogeneous mixture in which some of the particles settle out over time.

what is meant by cohesive property of water​

Answers

Answer:

cohesion; water is attracted to water

adhesion; water is attracted to other substances

Explanation:

adhesion and cohesion are water properties that affects every water molecule on earth and also the interaction of water molecules with molecules of other substances

Water cohesion is a property of water that allows its molecules to stay together. One oxygen atom is bonded to two hydrogen atoms to form a water molecule. Because of the charge imbalance, opposites attract, and water molecules form weak hydrogen bonds with one another.

Which of the following is NOT a property of water?

a
Frozen water floats on liquid water
b
Water covers most of the Earth's surface and retains a large amount of heat
c
Water molecules stick to each other through hydrogen bonds
d
Water cools very quickly

Answers

B pls do brainlyest
D. Water does float, as it is less dense, can take in a lot of heat and covers the majority of earth, and sticks to each other due to the polarity of water.

Water needs a big amount of energy added or removed in order to change phase.

7. If you have a 100-base pair DNA molecule that contains 45 cytosines, how
many adenines are there?

Answers

Answer:

5 adenines

Explanation:

Cytosine pairs with Guanine, and Adenine pairs with Thymine. This means, that if there are 45 cytosines, there must be 45 guanines. So that's 90 base pairs down. That means that there are 10 left between adenine and thymine- so that means there are 5 adenines

Answers

Answer:

b

Explanation:

cause a smart dude in the first comment section said so

Engage in water sports like surfing is the coastal location in Florida most likely to do if there are moderate winds and waves along the shore.

What is Coastline?

There are approximately 312,000 kilometers of coasts on the continents of the world (193,000 miles). They have changed positions during geologic time as a result of significant alterations in the relative levels of land and sea.

All coastal regions were impacted by sea level dips brought on by the loss of water from the oceans during glacial advances, according to studies of glaciations during the Pleistocene Era.

The sea level during the last Pleistocene glacial epoch is considered to have been nearly 122 m lower than it is now, exposing a significant chunk of what is now the continental shelf.

Therefore, Engage in water sports like surfing is the coastal location in Florida most likely to do if there are moderate winds and waves along the shore.

Discuss the possible outcome of an epiphyseal fracture in a 14 year old patient compared to a 40 year old one

Answers

Answer:

It could close growth plate in a 14 year old leading to shorter limbs or crooked limbs

Explanation:

Compared to a 40 year old patient, an epiphyseal fracture on a person of 14 years can be a cause for great concern.

The epiphyses are found at the ending of long bones. New bones are produced from here.

A person of 14 years is an adolescent and still at the puberty stage compared to a 40 year old. Such a person is not yet mature. An injury such as a fracture can cause the growth plate to close thereby disrupting the growth of the bone. A fracture through growth plate can cause shorter limbs.

The possible outcome of an epiphyseal fracture in a 14-year-old patient leads to shorter and crooked limbs.

What do you mean by Epiphyseal fracture?

An Epiphyseal fracture may be defined as a combination of a horizontal fracture line through the physis and a vertical fracture line that runs from the growth plate through the epiphysis to the articular surface.

The 14-year-old patient is under adolescence so their bone is not completely formed, while a 40-year-old patient almost completed the adulthood stage, so their bone is completely formed and strengthened, which may reduce the chances of bone adjoining.

Therefore, the possible outcome of an epiphyseal fracture in a 14-year-old patient leads to shorter and crooked limbs.

If Pat's has type A blood & his mom has type O blood which of the following blood
types must his dad have?

O Type O
O Type B
O Type AB

Answers

Answer:

type ab its more in formative

Pat's has type A blood & his mom has type O blood, the blood type of his dad must be the type AB blood. One of the parent must possess at least of copy of the A allele.  

For Pat having A type blood to have a mom with type O blood, it means, his genotype for the type A blood is heterozygous IAO. His mom's genotype is OO.

Therefore for a couple with the mom as OO to produce a child with AO, there are two scenarios; the father has to possess either AB or AA

If the father is AA and the mom is OO, their offspring could be all AO from the cross between the two.

                      A

        O          AO

If the father is AB and the mom OO, there is also there is also a 50% chance of producing a child with AO
