Chromosomes vs. Chromatids
- Hi, I’m getting really confused- what is the difference between chromosomes and chromatids? Are chromosomes always arranged in pairs- if so then when they undergo mitosis why do they only then seem to go into pairs to split!! Sorry I’ve just always been confused about this!!

Answers

Answer 1

Explanation:

Chromosomes carry DNA which is the genetic material of that organism.

WHILE.

Chromatids help the cell to duplicate and in turn aid in cell division.

I HOPE THIS HELPS

Answer 2
Chromosome are made up of two identical structures called the chromatid. No chromosomes aren’t always in pairs only during the notification cycle, because during DNA replication each DNA molecule makes an identical copy of itself and each strand is found in each chromatid that are bonded together by the centromere.

Give the NUMERICAL value to the following question. If a car was traveling 25
m/s and then accelerated at a rate of 5 m/s/s for 3 s, then what was the final
velocity?

Answers

Answer:

Given,

initial velocity= 25m/s

acceleration= 5 m/s

time= 3 s

final velocity= ?

We know that,

acceleration= final velocity- initial velocity/ time

or, 5 = final velocity- 25 / 3

or, 5*3 = final velocity- 25

or, 15+ 25= final velocity

Therefore, final velocity is 40 m/s.

describes lipids in water

Answers

Answer:

Ok

Explanation:

Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic. Hope this helped

The louse Cymothoa exigua lives inside the mouth of certain fish. It attaches to the fish’s tongue, strangling it until it falls out. Once the tongue falls out, the louse functionally replaces it. Generally, this is thought of as a parasitic relationship.


What criteria would need to be met for this relationship to be considered parasitic? Is it possible that this relationship could be an example of mutualism or commensalism? Use what you have learned to classify this relationship and explain your reasoning.

Answers

Answer:

A parasitic relationship is the one in which parasite or the organism that feeds upon the host benefits while the host organism is negatively affected.

This relationship cannot be classified as mutualism or commensalism

To Understand the relationship between louse Cymothoa exigua and fishes we need to understand the following:

What is a parasitism?

A parasitic relationship occurs when one creature, the parasite, feeds on another organism, the host, causing injury and possibly death to the host. A parasite lowers the fitness of its host while increasing its own, usually by getting food and shelter.

What is a mutualism?

Mutualism is a type of relationship in which both live organisms benefit equally and no one is harmed. Lichen is a mutualistic association between a fungus and algae, for example. ALgae provides food to fungus by photosynthesis and in return the fungus provides nutrients to algae.

What is Commensalism?

commensalism is a relationship between members of two species in which one derives food or other benefits from the other without harming or benefiting the other.Orchids are a type of flowering plant that grows on tree trunks and branches. Orchids rely on the host plant's branches for sunlight and nourishment.  on the other hand, they provide no benefit or harm to the host plants.

Hence this relationship cannot be an example of either mutualisma and commensalism because the host fishes are harmed as their tongue falls out due to  louse Cymothoa exigua and in return the parasite attaches itself to the host and feeds on them

Light that Moves and Molds Gels
Pitt research team demonstrates gels that can be moved, controlled by light

PITTSBURGH—Some animals—like the octopus and cuttlefish—transform their shape based on environment, fending off attackers or threats in the wild. For decades, researchers have worked toward mimicking similar biological responses in non-living organisms, as it would have significant implications in the medical arena.
Now, researchers at the University of Pittsburgh have demonstrated such a biomimetic response using hydrogels—a material that constitutes most contact lenses and microfluidic or fluid-controlled technologies. Their study, published in Advanced Functional Materials, is the first to show that these gels can be both reconfigured and controlled by light, undergoing self-sustained motion—a uniquely biomimetic behavior.

Together with Olga Kuksenok, research associate professor in the Swanson School, Balazs experimented with a newer type of hydrogel containing spirobenzopyran molecules. Such materials had been previously shown to form distinct 2-D patterns on initially flat surfaces when introduced to varying displays of light and are hydrophilic in the dark but become hydrophobic under blue light illumination. Therefore, Balazs and Kuksenok anticipated that light could be a useful stimulus for tailoring the gel’s shape.

Using computer modeling, the Pitt team demonstrated that the gels “ran away” when exposed to the light, exhibiting direct, sustained motion. The team also factored in heat—combining the light and local variations in temperature to further control the samples’ motions. Controlling a material with light and temperature could be applicable, Balazs said, in terms of regulating the movement of a microscopic “conveyor belt” or “elevator” in a microfluidic device.

“Imagine an apartment with a particular arrangement of rooms all in one location,” said lead author Anna Balazs, Pitt Distinguished Professor of Chemical and Petroleum Engineering in the Swanson School of Engineering. “Now, consider the possibility of being able to shine a particular configuration of lights on this structure and thereby completely changing not only the entire layout, but also the location of the apartment. This is what we’ve demonstrated with hydrogels.”

Explain how all the properties of water are related. Provide an example to describe the interconnectivity of each property. Be sure to include hydrogen bonding, polarity, surface tension, capillary action, cohesion, adhesion, high specific heat, and expansion upon freezing.

Answers

Answer:

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. The stream of water bends due to the polarity of water molecules.

All the properties of water are related to one another by the polar nature that is caused by the partial electronegativity difference of the hydrogen and oxygen molecules of water molecules.

A water molecule has  uneven distribution of charges between different atoms  of the different molecules. All types of properties of water due to attractions between these polar  molecules.

in water molecules slightly negative atoms of one molecule are  attracted to the slightly positive atoms of other  moleculesthe attraction forms hydrogen bonding, weak  bonds between a hydrogen atom and another atom

Properties of water due to polarity and hydrogen bonds:

surface tension - a measure  of the force necessary to  stretch or break the surface  of a liquidcapillary action - the tendency of water  to rise in a thin tubecohesion - water attracted to other water moleculesadhesion - Water attracted to  other materialshigh specific heat - the amount of  the heat that must be absorbed or  lost for one gram of the substance to change its  temperature by 1°Cexpansion upon freezing - ice is less dense than and on freezing it expands its structure and forms a cage-like structure.

Answers

Answer:

AlaskaWashingtonHawaiiCaliforniaOregon

Explanation:

Eruptions along the western edge of the United States have formed the Cascades volcanic mountain range.  Also, they develop island chains, such as the Aleutians in Alaska, which makes Alaska a potential volcanic eruption place. A prominent example of an eruption along the Ring of Fire was the dramatic eruption of Mount Saint Helens in Washington in 1980, which makes Washington a potential volcanic eruption state.  Deep beneath Hawaii, there is a fixed source of abundant rising magma, called a hot spot, making Hawaii likely to be a volcanic eruption state. In 2018, they added Salton Buttes to the 2018 assessment, which is a high threat of a volcanic eruption. In other words, California is likely to be a volcanic eruption state. Eleven of the eighteen very high threat volcanoes are in Oregon, and few other states, where explosive and often snow- and ice-covered volcanoes can project dangerous long distances to densely populated and highly advanced areas.

A) Monosaccharide
B) Simple sugar
C) Complex carbohydrate
D) Disaccharide

Answers

Answer:

A

Explanation:

monosaccharide is derived from mono, meaning "one", and saccharide, meaning "sugar". The common monosaccharides are glucose, fructose, and galactose. Each simple sugar has a cyclic structure and is composed of carbon, hydrogen and oxygen in ratios of 1:2:1 respectively. Although each sugar mainly exists as a cyclic compound, it is important to note that they are all in equilibrium to a small extent with their linear forms.

While galactose and glucose are composed of six-membered rings, fructose has only five carbon atoms bonded to each other in ring form.

Q: Explain why a coalition might be more effective at the local level than at the national level. Give
at least THREE reasons.

Answers

Coalition might be more effective at the local level than the national level because the people at the local level usually share same culture and have a common goal.

Coalition is a group that is formed by people or factions who partner and work towards a common goal. The main aim of coalition is to bring about a particular change.

Coalition might be more effective at the local level than at the national level because the people at the local level usually share common goal. Also, the people at the local level usually share a common culture unlike the national level when different cultures are being considered.

In conclusion, people at the local level also understands themselves better which helps in an effective coalition.
