Explanation:

I wanted to help u but I can't see the MCQ'S . I don't know  if it is my problem.

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.

Answer:

Carbon Dioxide and Water

Explanation:

Water and carbon dioxide are released as byproducts when you breathe.

Answer:

There are two main substances that are released during the process of celluar respiration. These substances are carbon dioxide and water.

Explanation:

Answer:

mRNA sequence: AUG; GCU; AAU; UGU; UGA

protein sequence: Met-Ala-Asn-Cys-stop codon (Methionine-Alanine-Asparagine-Cysteine-stop codon)

Explanation:

Transcription is the process by which a fragment of DNA (e.g., a gene) is used as template to synthesize a complementary RNA sequence, usually a messenger RNA (mRNA) sequence that is then used to synthesize a protein by the process of translation. In RNA, Adenine bases are replaced by Uracil bases. During translation, each codon (i.e., each triplet of nucleotides of the mRNA) indicates a specific amino acid (according to the genetic code).  UGA, UAA, and UAG are stop codons that signal the end or termination of translation.

Explanation:

Answer:

Although  the  light  dependent  reactions  of photosynthesis     are    not     affected     by changes in temperature, the light independent   reactions  of   photosynthesis are dependent  on  temperature.  They  are reactions  catalysed  by  enzymes.  As  the enzymes approach their optimum temperatures  the  overall  rate  increases.  It approximately   doubles   for   every   10°C increase    in    temperature.    Above    the optimum  temperature  the  rate  begins  to decrease, as enzymes are denatured, until it stops.

Explanation:

At  low  light  intensities,  as  light  intensity increases,the  rate of  the  light-dependent reaction,and   therefore   photosynthesis generally, increases proportionately (straight    line    relationship).    The    more photons  of  light  that  fall  on  a  leaf,  the greater     the     number     of     chlorophyll molecules  that  are  ionised  and  the  more ATP   and   NADPH   are   generated.   Lightdependent  reactions  use  light  energy  and so    are    not    affected    by    changes    in temperature.As light intensity is increased further, however, the rate of photosynthesis is eventually  limited by some other factor. So the rate plateaus. At very high light intensity, chlorophyll may be damaged and the rate drops steeply (not shown in the graph).Chlorophyll ais used in both photosystems. The wavelength of light is also important. PSI absorbs energy  most  efficiently  at  700  nm  and  PSII  at  680  nm.  Light  with  a  higher  proportion  of  energy concentrated in these wavelengths will produce a higher rate of photosynthesis.An    increase    in    the    carbon    dioxide concentrationincreases  the  rate  at  which carbon  is  incorporated  into  carbohydrate in  the  light-independent  reaction,  and  so the    rate    of    photosynthesis    generally increases until limited by another factor.As    it    is    normally    present    in    the atmosphere  at  very  low  concentrations (about  0.04%),  increasing  carbon  dioxide concentration  causes  a  rapid  rise  in  the rate  of  photosynthesis,  which  eventually plateaus   when   the   maximum   rate   of fixation is reached.

"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.

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.

10.What is holozoic nutrition?​

Ans. Holozoic nutrition is a method of nutrition that involves the ingestion of some complex organic substances that may be in the solid or the liquid state.

Answer:

23 pairs in meiosis 1 and 23 numbers in meiosis 2.

Explanation:

There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.

Because they are cold blooded they cannot control their body temperature, therefore their body temperature is always the same as their surroundings.

D, because if you burn fossil fuel the smoke while burning the fossil fuel is carbon dioxide and we live off fossil fuel and that means we use a lot of fossil fuel.

The missing part of the question is as follows:

Phrase indicates a limit to the scientific accuracy of the experiment?

Answer:

The correct answer is - a sample size of 300 people.

Explanation:

In the given research Marcus developed a drug that is already 200,000 people taking the drug, and the scientist takes sample size of only 300 people for the experiment.

The sample is very small as compared to the total population who participated in the research. A sample size of 300 people is very small compared to 200,000 people. Such a small sample size will not give the proper idea and any effective result, there would be chances to miss some aspect or effect of the drug to be missed, so, this can be the limiting factor to the experiment.

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.
