Your project is to characterize the cells with this mutation. Predict the defects you would most likely see in the mutant E. coli cells. Choose one or more: A. a delay in the unwinding of DNA B. rapid lagging-strand synthesis but slow leading-strand synthesis C. a delay in DNA polymerase beginning synthesis D. a longer total time to replicate DNA E. inefficient Okazaki fragment joining

this is true, but where is the problem? or do i just not see it?

Answer:

While some of the debris from the collision merged back into Earth, the gravity caused the accretion of much of the debris into a separate ball, forming the Moon.

Answer: C. scorpions have changed as a result of natural selection

Explanation:

The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.

The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.

The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.

"The real answer is It is a barrier with tiny openings that let some, but not all, materials pass through"

Answer:

Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.

Explanation:

The real answer is It is a barrier with tiny openings that let some, but not all, materials pass through.

Photosynthesis is the answer. Green plants remove carbon from the atmosphere by photosynthesis.

Answer:
My question: Does a plant grow better when you mist it with water or pour it?

Hypothesis: The plant grows better if you pour water on it.

Research: According to gardendesign .com watering your plant with a hose is much better, and watering it in early morning/ late evening is better.


Experiment: Over the course of 2 weeks(or however long), I will watch 2 plants grow and see if msiting one plant versus pouring water on the base is better.

Materials:
-2 grass plants
- watering can ( for pouring)
- spray bottle( for misting)
- area on a windowsill where sunlight can enter.


Procedure:
1. First we put the grass plants in separate pots.
2. Water the plants in the same timeframe, such as every 3 days.( at either early morning or late night)
3. Leave them in the suncast window
Doing the experiment:
As I watched the plants, they both grew overtime, but one more than the other.
Data gathered:
One plant turned yellow while the other grew lusher.
Organized data:
week1 week2 week3
plant 1(pour)- green, taller I green, taller I green, taller
plant 2(mist)- green, same height I yellow, shorter I brown, shorter
Analyze data:
The plant with water poured in was lusher because there was more water going to its roots, while the other plant that was misted turned yellow, brown, then died because there was very little water going to its roots.
Conclusion:

My claim was correct, because when we poured water, the plant was healthier, and when we misted it, the plant died.

3. The parts of a simple scientific experiment are the purpose(why you are doing it), the research(to find out more on the topic), the hypothesis(prediction of outcome), the experiment(procedure to see if hypothesis is right), and then the analysis( to see what to change to make hypothesis correct, or see if it was correct)

4. What this experiment was about was a simple investigation to see whether watering a plant by misting or pouring was better. I wanted to see which one would work better to find an effective way to water my plants. What this investigation taught me was that when we water our plants, we need to pour it. I figured this out through research and articles stating how pouring water with a watering can or using a hose in the soil was better than just misting it with a spray bottle, as it was more effective. This outcome came through a mildly long test experiment, which happened over the course of 3 weeks. What I analyzed from that was that if we water a plant through a spray bottle just on the leaves, it really doesn't help the plant, as the roots are the ones that need water, so that they can internally give it to the leaves. That is why I rest my case of how watering plants by pouring is better than misting it.

Photosynthesis. Plants take water from the roots, nutrients from the sunlight and carbon dioxide from the air to make carbohydrates

Explanation:

Saprophytes aren't green. The saprophytic plants don't contain chlorophyll so they aren't green in color

Answer:

Box 1.

Explanation:

The box 1 have the more mass because there are more number of balls present in the box while on the other hand, box 2 has less number of balls in the box. The volume of box boxes are the same as well as weight of the both boxes before placing of balls in it. Placing of balls changes the weight of both boxes because of the presence of different number of balls in each boxes that increases its weight.

Adaptations - Darwin's Finches. Here are some adaptations of particular finches and the finches as a whole. ... The birds with bigger beaks survived, and the rest adapted by having developed strong and big beaks, or developed beaks that allow them to use tools to reach their food.

Hope it helps...

These varied habitats results in adaptive radiation which is responsible for evolution of the finches on different islands.

What is evolution?"Evolution is change in the heritable characteristics of biological populations over successive generations."What is adaptive radiation?"Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available."

The small finches had to change its type of nutrient(eating seeds, small worms, etc.) in order to survive on the varied habitats of island. This results in their evolution.

Hence, adaptive radiation occurs due to varied habitats.

Mechanical digestion takes place in the mouth

Mechanical thing replaces the tongue

Answer:

1. Digestion helps to break down the food into simple, soluble form.

2. Name the process by which absorbed nutrients are utilized by the body?

Ans. Assimilation is the process by which absorbed nutrients are utilized by the body.

3. Where does initial digestion of protein take place?

Ans. Mechanical digestion of protein begins in the mouth and continues in the stomach and small intestine. Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.

4. Where is the water absorbed from undigested food in the digestive system?

Ans. Water from the undigested food is absorbed mainly in the large intestine.

5. Name one animal that lives on liquid food only.

Ans. Mosquito lives on liquid food only. They rely on human blood for their food.

6. The process of taking in food into the human body is called ingestion.

Ans. True.

7. The alimentary canal stretches from mouth to anus.

8. What is rumen?

Ans. Rumen is the largest compartment of the stomach of a ruminant in which cellulose is broken down by the action of symbiotic microorganisms. The primary function of the rumen is as a storage compartment to facilitate microbial (bacterial and protozoal) fermentation of ingesta.

9. Which animals are called ruminant?

Ans. Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach, they have four. Of the four compartments, the rumen is the largest section and the main digestive centre.
