Answer:
Maize is monocot and fibrous roots whereas mustard is dicot and tap roots system.
Explanation:
The main difference between maize plant and mustard plants is that Maize is a monocot plant means only one cotyledon in their seed whereas Mustard are dicot which means having two cotyledons. Maize plant has a fibrous root system whereas mustard plant has tap root system. The leaves pf maize plant have parallel venation while on the other hand, the leaves of mustard having reticulate venation. The seeds of maize is bigger in size as compared mustard seed.

Which is a possible outcome of global warming?
A. Hurricanes and other extreme weather will increase
B. Most crops will grow better in warmer climates
C. Sea levels will drop all around the world
D. Disease will not be able to spread as quickly
A possible outcome of global warming is that hurricanes and other extreme weather events may increase. Therefore, the correct statement is option A.
What causes an increase in the temperature of Earth?The gradual rise in the Earth's atmosphere's average temperature that results from the buildup of greenhouse gases, primarily carbon dioxide, released by human activities like the burning of fossil fuels and deforestation is known as global warming.
The Earth's climate and weather patterns may alter as a result of this temperature rise, which might result in more frequent and severe weather events like hurricanes, floods, and droughts.
Due to alterations in precipitation patterns, increased pest pressure, and other factors, it is unlikely that most crops will grow more effectively in warmer climates. Because of the melting of glaciers and ice caps, sea levels are more likely to increase, resulting in floods in low-lying places.
Therefore, a possible outcome of global warming is that hurricanes and other extreme weather events may increase.

Suppose you traveled back in time and located the first animals to have evolved feathers. You found that these animals were tree-dwelling ectotherms, able to run quickly but unable to fly. You also noticed that only males had feathers. Which hypothesis of feather evolution would these data most support? Feathers initially evolved in a role associated with ________.
Answer:
Feathers initially evolved in a role associated with sexual selection.
Explanation:
In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.

Which is an example of genetic drift?
Answer:
Explanation:
Genetic drift, gene flow, mutations, and natural selection are responsible for the change in the gene pool over time. Example of genetic drift: a population of rabbits with alleles B and b, both alleles are present in equal frequencies p = 0.5 and q = 0.5 if 10 parents reproduce the probability of having an offspring with alleles B or b is 0.5; however, by chance, a slight difference in the offspring allele frequency might occur due to random sampling. As a result, in the next generation, the allele frequencies will change slightly to new frequencies by chance to become p = 0.4 and q = 0.6. in the following generations, the random sampling of alleles continues and the change in allele frequency will be greatly different from the initial 0.5 frequency due to genetic drift. Even though genetic drifting is one of the factors that participate in the evolutionary process of the genetic pool by increasing or decreasing a certain allele’s frequency, however, it does not influence the adaptation of individuals to the environment since the affected genes may be harmful or beneficial genes.

Explain what will happen to your eyes when..
a) you move in a very bright light.
b) you move in a dim light
Answer:
For A your pupils will shrink for B your pupils will dilate.
Answer:
When you look at something that is bright, your pupil may shrink.
When you look at something dim, your pupil may get larger.
Explanation:
I think your pupil may get larger if you look at dim light because your eye may have a hard time seeing what's going on. And the opposite may happen when you look at bright light.

1. Scales are used to figure out the ratio of the distance in the map to the actual distance between locations.
A. what is the name of two different types of scales found on maps?
B. how does each scale work?
Answer:
Bar and lexical.
Explanation:
Bar and lexical are the name of two different types of scales that are found on maps. Bar scales are used more frequently in the maps because they represent or show the distance ratio visually instead of in words, while on the other hand, lexical scales may be expressed in words, as a ratio, or as a fraction. Examples are 1:10,000 or 1/10,000. Using map scales is very important in the real world if you want to find out the distance you are traveling.
Use an examples to distinguish dominant and recessive phenotypes.
I'm a bit stuck and need some help. Much appreciated!
Think recessive phenotypes as paper and dominant phenotypes as teared paper. Once paper is teared, it can't be fixed. Not even tape. It'll just leave that mess exposed. Same with dominant phenotypes. It just takes one dominant trait to change the looks of future offspring.
If you don't tear the paper, everything is fine. Same with recessive phenotypes. As long as there's no contact with any dominant phenotypes, the looks of future offspring will change.

At the time Hutton proposed his ideas about the age of rocks, how old was Earth believed to be by most people in Scotland?
Answer:
In the late eighteenth century, when Hutton was carefully examining the rocks, it was generally believed that Earth had come into creation only around six thousand years earlier (on October 22, 4004 B.C.
James Hutton was a Scottish naturalist and geologist who discovered the age of the earth. The earth was believed to be 6000 years old by the Scottish people.
Who was James Hutton?
James Hutton is the father of modern geology and was involved in the discovery of the earth's age and the soil formation from the parent rocks. He made his contribution to discovering the age of Earth based on his observation rather than on assumptions.
Before he discovered the earth age, it was believed by the Scottish people that the planet was six thousand years old. He discovered the process of soil formation by weathering the parent and bog rocks that accumulated as sediments over years and allowed the discovery of the planet's age.
Therefore, it is believed that the earth was 6000 years old.

Why making anti-viral medicines is harder than making anti-bacterial medicines ?
Also Is Virus a living parasites?
Answer:
Making anti-viral drugs is more difficult than making anti-bacterial medicines because viruses have very few biochemical mechanisms of their own. They make use of host machinery which replicates. So it is very much difficult to find the targets where these drugs get interfered by not making any harm to the host. Thus, it is not easy to design an antiviral drug with high safety and effectiveness.
Explanation:
And i would say virus is a parasites but not a living parasite according to md
Answer:
Because antivirals can damage host cells where the viruses reside.
I hope this helps
all viruses are obligate parasites,that is they lack metabolic machinery of their own to generate energy or to synthesize proteins,so they depend on host cells to carry out these vital functions...
