In an experiment on the cell cycle, a researcher repeatedly injects a mouse with a variety of cyclin-dependent kinases, including mitosis-promoting factor (MPF). The compounds are delivered to the thyroid gland through a carrier complex in the blood. As the experiment continues, which change to the thyroid gland of the mouse is most likely to occur?
Answer:
A cancerous tumor will form in the thyroid
Explanation:
Cyclin-dependent kinases are proteinous in nature. They perform z series of biological activities in the body. They are responsible for controlling the cycle of a cell.
Cyclin-dependent kinases when they are mutated can cause the cells present in the human body to begin to multiply and divide uncontrollably thereby resulting in the formation of cancerous cells in the body.
This is why when a researcher repeatedly injects a mouse with a variety of cyclin-dependent kinases, including mitosis-promoting factor (MPF) and they are delivered to the thyroid gland by carrier complex in the blood, the cells in the thyroid would start to multiply uncontrollably thereby causing a cancerous tumor to be formed in the thyroid.

The fact that the zebra's stripes are passed down in its DNA indicates that the stripes may serve an evolutionary advantage. What do you think is the evolutionary need for such complex designs?
Answer:
Camouflage and other visual illusions
Explanation:
There are several theories for why zebras have evolved to have striped coats. One of the lines of thinking is that it allows them to blend into long grass to avoid predation. The stripes blend into a sort of gray colour at a distance, making them difficult to spot.
The stripes may also "dazzle" their predators, because the properties of black and white stripes can give the illusion of movement. If there are many zebra huddled together, some moving, some not, it may be difficult for a predator to lock on to its prey.
It could be some sort of deterrent to stop bugs and other pests, because they can less successfully land on striped patterns.
Answer:
Oftentimes, these exotic prints serve as camouflage so the animal can hide from predators. Sadly, such beautiful animals are also poached by hunters who use their furs for clothing and rugs, which has led to many of these wild animals becoming endangered.

A hypothesis is important in a scientific investigation as it provides a preliminary explanation that guides the experiment's design and results interpretation. It allows researchers to know what they are testing for and gives them a standard to which they can compare their results.
Explanation:A hypothesis is a preliminary explanation for a phenomenon used as a basis for further investigation. It is important in a scientific investigation for several reasons.
Option D correctly states: Without a hypothesis, you have no statement to which you can compare your results to in order for you to determine what those results mean.
A hypothesis provides scientists with a clear focus. It prompts the design of an experiment or observation to test whether the proposed hypothesis is true or false. If there were no hypothesis, it would be difficult to know what to test for and how to interpret the results. Moreover, a hypothesis is either supported or refuted based on the results of the experiment, thus providing a basis for understanding and further exploration.

Answer:
False
Explanation:
The autonomic nervous system supplies the organs of the body such as intestine, kidney etc and also controls the body functions.
It comprises of the sympathetic and parasympathetic nervous system.
SOME and not all visceral organs receive dual innervation(nerve supply) from both the sympathetic and parasympathetic divisions of the autonomic system and it’s dependent on the functions of the organ.
Yes, it is true that all visceral organs receive dual innervation from both the sympathetic and parasympathetic divisions of the autonomic nervous system. The sympathetic system readies the body for physical activity, while the parasympathetic regulates resting activities.
Explanation:The statement is true, all visceral organs do receive dual innervation from both the sympathetic and parasympathetic divisions of the autonomic nervous system (ANS). Dual innervation means that the visceral organs are supplied by both divisions of the ANS - the sympathetic and parasympathetic systems. The sympathetic division generally prepares the body for intensive physical activity (fight or flight), while the parasympathetic division regulates resting or digesting activities. For example, the heart rate is accelerated by sympathetic stimulation and slowed by parasympathetic stimulation.

To lyse is to burst apart or explode. Why do you think a virus’s reproduction cycle is called the “lytic cycle”?
will give Brainliest
Answer:
cells burst to release new viruses
After a cell has been used to reproduce new viruses, a special viral protein causes the cell's membrane to break open, or lyse. This process gives the lytic cycle its name.
Explanation:
Hope this helps : )
Final answer:
The lytic cycle is named as such because it culminates in the lysis, or bursting, of the host cell, releasing new virus particles. It contrasts with the lysogenic cycle, where the virus integrates into the host genome and replicates without lysing the cell.
Explanation:
The term "lytic cycle" describes a type of virus replication in which a virus invades a host cell, uses the host's cellular machinery to replicate its viral genome, and manufactures more virus particles. Eventually, the host cell becomes so full of new virions that it bursts, or undergoes lysis, releasing the new viruses to infect additional cells. This process of cell bursting is why the cycle is referred to as 'lytic' since 'to lyse' means to burst or explode.
Bacterial cells that are infected by viruses (bacteriophages) usually end up being destroyed through this process. However, not all viruses follow the lytic cycle; some may enter a lysogenic cycle, where the viral DNA is incorporated into the host cell's genome and replicated along with the cell's DNA without destroying the host. An example of this dual behavior is seen in the phage lambda of E. coli, which can undergo both the lytic and lysogenic cycles.

Population density is the average number of individuals per unit area or volume, indicating how crowded a population is, whereas population distribution explains how these individuals are spread out across their habitat, which can be clumped, uniform, or random. This indicates different environmental and behavioral factors affecting the species.
Explanation:Population Density vs. Population Distribution
Understanding both population density and population distribution is essential to grasp how individuals within a species are spaced within their habitat. Population density refers to the average number of individuals per unit of area or volume. This is a measure of how crowded a population is. For example, the number of trees per acre in a forest is an expression of population density.
On the other hand, population distribution delineates how the individuals are spread out across their habitat. This can vary greatly, with populations sometimes clustered around resources in aggregations, while others might be evenly spaced due to territorial behavior or randomly distributed if there are no strong interactions or environmental preferences dictating their position.
To concrete this difference with an example: If a population of 820 insects lives in a 1.2-acre area, their population density would be roughly 683 insects per acre. On the contrary, a population of 560 flowering plants in a 0.2-acre area has a startlingly higher density of 2,800 plants per acre. Consequently, the plants have a greater density than the insects. The pattern of distribution of these organisms could tell us a lot about their behaviors and interactions with the environment and other species.
Population distribution patterns – such as clumped, uniform, or random – offer insight into environmental resources, species interactions, and behavioral strategies. For instance, a species demonstrating a random distribution might not be influenced strongly by social interactions or might exploit resources that are evenly spread across an area. In contrast, a uniform pattern typically indicates competition for resources or territorial behavior.

The amount of force needed to keep a 0.3 kg box moving at a constant speed of r m/s of frictionless ice is?
A.) 0N
B.) 10N
C.) 1.2N
D.) 0.3N
E.) 2N
Answer:
0N
Explanation:
If an object is on one of these imaginary frictionless surfaces, the surface does not present any opposing force (frictional force) to slow an object sliding over it. Therefore no force is needed to keep the object moving.
The amount of force needed to keep a 0.3 kg box moving at a constant speed of r m/s of frictionless ice is 0 N.
What is frictionless ice?
Two fundamental ideas related to the concept of force are established by the First Law. The "natural condition" of motion of all objects is not rest, as almost everyone would assume, but rather any constant velocity.
when they were finally given the freedom to act spontaneously, the velocity they had. In our daily lives, things frequently come to rest. Newton's insight that this was caused by the frictional force is what makes him so brilliant.
Objects float with whatever velocity they have from their prior interactions in space, far from the influences of gravity and air resistance, demonstrating the First Law.
Therefore, The amount of force needed to keep a 0.3 kg box moving at a constant speed of r m/s of frictionless ice is 0 N.

Two rivers run into the ocean. One river is very long. The other is
very short. Which river probably drops the smallest rock pieces near the ocean?
Explain your answer.
Answer:
the very long river
Explanation:
Larger rocks tend to settle out of the water flow sooner than smaller rocks do, so the rocks remaining at the end of a very long river would tend to be very small. A very short river may still be carrying somewhat larger rocks.
The very long river probably drops the smallest rock pieces near the ocean.
_____
Perhaps the implied assumption here is that a very short river will have a higher gradient than a very long river. Another assumption is that rocks are picked up nearer the headwaters, and the gradient decreases with distance.
If both rivers end at a waterfall into the ocean, they may very well carry the same sort of rock size distribution. If the short river traverses muddy terrain, and the longer river traverses rocky terrain, the answer may be reversed.

C. chromosomes
During cell division, The DNA in a eukaryotic cask is tightly packed and coiled into structures called:
C. chromosomes.
- During cell division, the DNA in a eukaryotic cell is tightly packed and coiled into structures called chromosomes.
- These chromosomes contain the genetic material necessary for cell division and inheritance.
- Chromosomes are condensed structures formed from DNA and associated proteins, primarily histones.
- Prior to cell division, DNA replication occurs, resulting in duplicated chromosomes called sister chromatids.
- As the cell prepares for division, these sister chromatids condense further and become visible under a microscope as distinct chromosomes.
- Chromosomes play a crucial role in ensuring the accurate segregation of genetic material during cell division, allowing for the transmission of genetic information to daughter cells.
- Therefore, chromosomes are the condensed and coiled structures that contain the genetic material essential for cell division and inheritance.

Which storm likely had more rainfall?There were two rainstorms in Hatfield last summer. Before Storm 1, Hatfields temperature was 32°C. Before Storm 2, the temperature was 18°C. Before both storms, the temperature of the surrounding areas was the same and wind was blowing toward Hatfield. There was the same amount of water vapor before Storm 1 and Storm 2.
Answer:
Storm 1 had more rainfall.
Explanation:
Storms are usually characterized by a large variety of atmospheric disturbances which can range from normal rainfall to wind-related disturbances. Storms are formed when a center of low pressure develops with the system of high pressure surrounding it which can create winds that result in the formation of storm clouds. The amount of moisture then determines the amount of rainfall.
Therefore at Hatfield, storm 1 had more rainfall due to it's higher temperature which made the air warmer and easy for the wind to push air parcels even higher into the clouds making it to lose more energy and causing more rainfall.

Answer:
The stages of cell cycle are G1 phase, S phase (synthesis), G2 phase and M phase (mitosis and cytokinesis).
Explanation:
G1 phase is also called growth phase of the interphase. This phase occurs after the completion of M phase which consist of mitosis and cytokinesis and before the starting of DNA replication. S phase is a synthesis phase where DNA replication occurs. G2 phase is an important phase in which cell grow in size occurs and various proteins are produced which is necessary for the mitosis. After G1 phase, mitosis occurs in which a single is divided into two daughter cells having diploid chromosomes.
