a. Viruses reproduce using a ______ _____.
b. What are the differences between proviruses and viral DNA?
c. Why is the common cold virus so difficult to cure?
Answer:
Viruses reproduce using a host cell
The differentce between proviruses and viral DNA is A provirus is a virus genome that is integrated into the DNA of a host cell. In the case of bacterial viruses (bacteriophages), proviruses are often referred to as prophages. However, it is important to note that proviruses are distinctly different from prophages and these terms should not be used interchangeably.
Common cold virus is difficult to cure because Unfortunately, antibiotics — medications that treat bacterial infections — cannot treat or cure a common cold. That's because colds aren't caused by bacteria. Some people report that they've had a cold, took antibiotics, and felt better after a few days of the medication.

What are temperate grasslands?Temperate grasslands are biomes characterized by vast expanses of open grasslands with few trees or shrubs. These ecosystems experience a wide range of temperature fluctuations between seasons, with hot summers and cold winters. As a result, animals that live in temperate grasslands have evolved adaptations that enable them to survive in this challenging environment. One of the most common adaptations of grassland animals is the ability to dig burrows. Burrows provide shelter and protection from predators, as well as a stable microclimate for animals to live in.
Hence, structures to dig burrows are a common adaptation for animals that live in temperate grasslands, as is present in the first option.

C.This population of mammoths appear to be in Hardy-Weinberg equilibrium since no allele frequencies are changing over time.
D.Individuals with thick fur migrated into the population of mammoths, increasing the proportion of these individuals.
PLEASEEE HELPPP MEEEE!!!!
Answer:
Individuals with thicker fur had a survival advantage in the cold
Explanation:
Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.
Why natural selection occurs?Natural selection takes place due to 3 underlying reasons:
ReproductionHeredityVariation in fitness of organisms.Due to these reasons, natural selection can leads to speciation.
As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.
Thus, option A is correct.

Draw the structure of ATP molecule and explain how it is formed
ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.
ATP molecule is formed in the process of respiration i.e. aerobic and anaerobic. During aerobic cellular respiration, glucose reacts with oxygen in the mitochondria of the cell, forming ATP that can be used by the cell in different cellular activities. When glucose reacts with oxygen, three molecules are formed i.e. ATP, Carbon dioxide and water. ATP is used by the cell whereas the Water and carbon dioxide molecules are waste materials which are removed from the cell so we can say ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.Learn more about ATP here: https://brainly.com/question/893601

What is one of the results of an increase in the amount of greenhouse gases in the atmosphere?
А
increased overall ocean salinity
B
decreased global polar ice melting
с
increased overall atmospheric humidity
D
decreased global surface temperatures
Answer:
C) Increased overall atmospheric humidityIncreasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.
What are greenhouse gases?The gases that trap heat in the earth's atmosphere are referred to as greenhouse gases. The earth's surface warms during the day when the light beams through the atmosphere. The earth's surface cools at night, redistributing heat into the atmosphere. However, part of the heat is captured by the atmosphere's greenhouse gases.
Due to minute concentrations of water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) in the atmosphere, the Earth has a natural greenhouse effect.
Increasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.

Answer:: De-termination could offer experiences into development and normal assets that are at present inaccessible to us.
2: Compromised or harmed biological systems could be reestablished with the assistance of specific now-wiped out species.
3 In the event that people drove plant and creatures species into termination, maybe we owe it to these species to attempt to bring them back.
4 De-elimination could be a major advance forward for hereditary designing.
There are loads of valid justifications to bring back wiped out creatures. All creatures perform significant jobs in the environments they live in, so when lost species are returned, so too are the 'positions' they once performed. Wooly mammoths, for instance, were nursery workers. ... It very well may be something similar for other de-wiped out creatures, as well.
Zeroing in on de-elimination could think twice about by redirecting assets from protecting environments and forestalling more current eradications. It could likewise diminish the ethical load of annihilation and backing for imperiled species, sending the mixed signal that resuscitating a wiped out creature or plant is trifling

HELP QUICKLY Why are the deepest high tides so deep and the shallowest low tides so shallow? Hint: how are the Earth, Sun, and Moon aligned?
There are different kinds of tides. This change occur because when the gravitational pull of the sun works along with the gravitational pull of the moon on Earth, it leads to the oceans bulging out.
This result above makes the high tides as been little higher and low tides been little lower than normal.Spring tides are known to be the deepest as oceans levels are highest in this kind of tide. The neap tides are known to be the shallowest.
This often occurs when the moon, earth, and sun are said to be at a right-angled plane. Therefore, the gravitation pull of the moon and sun on the oceans do counteract each other making its net effect is smaller.

How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experiment mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table.
Genetic variation helps to drive natural selection and potentially, evolution. Red, white, and striped beans (mice) represent offspring that are the product of meiosis and sexual reproduction. Black and speckled beans (mice) are the result of mutations. Using the student data analyze the effects of these mutations on natural selection.
A) The color mutations provided a survival advantage to these two populations of mice.
B) The advantage of the mutations is dependent on the environment and external conditions.
C) While mutations provide genetic variation they did not play a role in natural selection.
D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
Answer:
D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
Natural selection refers to the observation that organisms that are more suited and adapted to their environment live long enough to survive and reproduce thereby passing on their favorable characteristics to their offspring.
The mutation in which the mice became speckled was shown to be an advantage from the table. Hence, the speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
