If a cell does not go through the Sphase of the cell cycle before mitosis, what might be wrong with the daughter cells?

Answers

Answer:

Synthesis is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.

Explanation:

If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.

Each step in the cell division is controlled and regulated by proteins like Cyclins. If a cell does not go through the S phase, it can not go to the G2 phase until the replication process is completed, or until it's programmed cell death.  

-----------------------------------------------

As the cell passes through different steps of cell division, there are auto control mechanisms to ensure that the step was correctly performed and the cell is ready to go to the next step.  

Many regulator molecules act during the different stages of the mitosis process to make it possible.

There are too many factors interacting, activating, and deactivating to pass from one stage to another.

Cyclins are proteins that regulate the whole cell cycle. There are different types of cycling, each of them acting on a different stage.

When the cell is going through one of the stages, the only cyclin in high levels is the one that is regulating that cycle.

Once that stage is over, that cyclin concentration decreases, and the following one increases.

But if any step was not correctly performed, the cell can not pass to the following one.

During the S stage of the interphase occurs the DNI replication process.

At this point, also occurs the synthesis of histones and other associated proteins.

This is the only stage where the DNI molecule is replicated.

S phase cyclins are in charge of regulating the stage of DNA replication.

If the cell does not go through the S phase, the cyclins of this stage are not activated. And if S phase cyclins are not active, the cell can not go to the G2 phase.  

The cell remains in the S phase until the DNA replication process is correctly done. And if it does not occur, the cell suffer programmed cell death.

Which of the following bones are considered to be the MOST proximal?
metatarsals
clavicle
ulna
olecranon

Answers

Answer:

Of the group of bones mentioned, the most proximal is the clavicle, which is part of the shoulder girdle.

Explanation:

Proximal is a reference term used in anatomy to indicate the structures that are closest to the center of the body.

The bones mentioned -clavicle, olecranon, ulna and metatarsals- are related to the function of the limbs. The clavicle is the closest bone to them, located between the neck and the thorax, on each side of the midline of the body.

Regarding the other options, other bones are distal, as they move away from the center of the body. In order from less distal to more distal they are found:

Olecranon, which is a bone eminence of the ulna, in the upper limb. Ulna or cubitus, which is part of the bones of the forearm. Metatarsals are the bones that form part of the foot.

Aliyah found a tarnished silver dollar and recalled that tarnish results when metals react with oxygen or sulfur compounds in the air. She polished the silver dollar to remove the tarnish until it was shiny again. She also polished a copper bracelet and a gold ring. What physical property of these metals makes them shiny?

Answers

Answer:

LUSTER

Explanation:

The physical property of the metals that make them shiny is called Luster. Therefore, Aliyah was able to polish the metals like silver, copper, and gold.

What is luster?

Luster is one of the important physical properties of the metals, which refers to the way light is reflected from the surface of the metal. In the context of metal, luster refers to the shininess or brightness of the metal surface.

The luster of a metal ranges from dull to very shiny and can influence the perceived value of the metal as well as its suitability for various applications.

The luster of a metal can be affected by factors such as surface roughness, impurities, and exposure to environmental conditions such as corrosion and oxidation.

The treatment of a metal surface, such as polishing and plating, can also impact the luster of a metal.

When you feel cold, there are sensors in your skin that tell the brain you need to warm up. The brain sends messages, by way of nerves, to the muscles in your body causing them to contract and relax very quickly resulting in a shiver. The movement of the muscles during a shiver generates heat which can be used to warm up the surrounding tissues. Which characteristic(s) of life is being represented during this action?
A) respond to stimuli
B) maintain homeostasis
C) growth and adaptation
D) respond to stimuli and maintain homeostasis

I think it is D because your responding to the cold from stimuli and by creating heat to keep your body the average temperature it is homeostasis.

Students in a science class visited four local ecosystems. The students observed the species present in each ecosystem and recorded their observations in the table.


Based on these observations, which ecosystem is likely to be the least sustainable?

A.Ecosystem 1, because it has the fewest species
B.Ecosystem 2, because it includes both aquatic and terrestrial species
C.Ecosystem 3, because it has few predators
D.Ecosystem 4, because it supports many animals

Answers

the answer is A

this is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem

This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.

What is Ecosystem?

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.

Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.

Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.

Explanation:

A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.

Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.

b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
