Answer:
This shows that once animals were on the surface there were plants for them to eat.
Dinosaur fossils show up only in layers above or with plant fossils. This shows that dinosaurs were animals that lived with plants and feed on plants.
What are fossils?Fossils are the remains of plants, animals, and other substances that are preserved under the layers of rocks and earth. They are the preserved form that gives the knowledge of organism present in before times.
Dinosaurs lived 65 million years ago, but still, their bones and remains are found on earth. They were found with the fossils of plants, so this tells us that plants were also present at the time of their presence, and they fed on plants.
Thus, only strata above or in conjunction with plant fossils do dinosaur fossils appear. This demonstrates that dinosaurs were also plant-eating and lived with plants.

When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity?
a) the ions in the solution interact with the sugar and that interferes with its solubility
b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not
c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water
Answer:
c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
Explanation:
A solution contains a solvent (water in this case) and a solute (sucrose in this case). A solution can either be saturated or unsaturated depending on whether it can still dissolve a solute or not.
According to this question, the 0.7 M sucrose solution does not dissolve the sucrose (solute) any longer. This implies that the sucrose solution is getting SATURATED. The saturation of the sucrose solution occurs because the amount of solutes is equating the amount of solvent in the solution.
The solubility of a solution depends upon polarity. The solute molecules (sucrose) adhere to the polar regions of the water molecules (solvent). When this occurs to the point where no other sucrose molecule can adhere, the solution becomes SATURATED so there is no room for more sucrose molecules.
4. Distinguish between the types of scientific
investigations. Does all scientific knowledge
come from experimentation? Explain your
answer. SC.7.N.1.3
Answer: Descriptive, Comparative and Experimental (which comes from experimentation).
Explanation:
There are three types of scientific investigations:
Descriptive: This type of scientific investigation studies parts of a system, which can be natural or artificial. It describes everything that is being studied and no predictions are made. There are three types of descriptive methods: case-study methods (an in-depth study is produced from many sources with different methods), observational methods (no questions asked, just an observation of the behavior of a subject and no manipulation of the variables), and survey method (some people are interviewed and the researchers study the answers.)Comparative: It gathers information from organisms, systems, places or from any source, to compare them using also a control group. But, there is no imposed treatment because it is not ethical or because it is not possible. So, the treatment is only observed.Experiment: As its names says, it uses an experimental test designed to study some phenomena, where variables are controlled so the treatment is not only observed as the comparative method. Then those variables are measured to collect information or evidence that supports or not a previous hypothesis and is used to assess theoretical knowledge. The independent variable is manipulated while the dependent variable is measured. This type of scientific investigation comes from experimentation.I want to see how tall plants will grow depending on what they are planted

students spend doing chores every night and their average grades on
schoolwork. Which statement from the lab report best represents a
conclusion?
A. Based on our results, students who do 1 hour of chores per night
have grades that are on average 0.2 points higher than students
who do no chores.
B. Doing chores at night actually helps students do better at school,
even if it seems like the opposite would be true.
C. We believe that students should spend at least 2 hours doing
chores every night if they want to get better grades at school and
help their families.
OD. If students spend at least 1 hour per night on chores, then they are
guaranteed to get higher grades on their schoolwork.
Answer:
A. Based on our results, students who do 1 hour of chores per night
have grades that are on average 0.2 points higher than students
who do no chores.
Explanation:
In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.
From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.
The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.

Compare pure water and coffee. Their pH differs by approximately
Answer:
They differ by two positions in the pH scale.
Explanation:
Hello,
In this case, since coffee has an pH of about 5 which is slightly acidic and water has a pH of 7, their pH differs by 2 approximately:
[tex]\Delta pH=pH_{water}-pH_{coffee}=7-5=2[/tex]
Such acidity in the coffee is caused by the presence of the well-known chlorogenic acid which is besides helpful for us towards reducing the degree of tiredness we eventually acquire along the day.

Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'
Hello. This question is incomplete. The full question is:
A tRNA anticodon is 5' GAA 3'.
Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'
Answer:
a) 5' UUC 3'
Explanation:
Anticodons are sequences of nitrogenous bases that establish complementarity with sequences of nitrogenous bases in a codon.
As you know, mRNA has the nitrogenous bases Adenine (A), cytosine (C), guanine (G) and uracil (U). In this system, guanine is supplemented with cytosine and adenine is supplemented with uracil.
These bass are organized into codons, which are a set formed by 3 of these bases.
The tRNA has the same bases, but its codons must recognize and complement the codons of the mRNA, being then called Anticodons.
In this case, if a tRNA has the anticodon 5 'GAA 3', it must bind to codons 5 'UUC 3' in the mRNA.

Plant Species Adaptation Turkey Feet Grass This plant has very deep roots to prevent soil loss in windy areas, and to help anchor the plant. Pinkflower Hedgehog Cactus Contains spines for protection, and a waxy coating on the sunny side of the plant to help prevent water loss. Devil’s Walking Stick Secrete chemicals as a defense mechanism, and have broad leaves to catch sunlight in shady areas. Hairy Manzanita Pale pink flowers attract humming birds for pollination. Which plant species above is best adapted for a grassland biome? a Turkey feet grass b Pinkflower hedgehog cactus c Devil's walking stick d Hairy Manzanita
Answer:
A) Turkey feet grass
Explanation:
Grassland biome is one of the biomes that makes up the Earth's biosphere. Due to the characteristics of this biome (grassland), it favours the abundance of grass species over trees and shrubby plants. These characteristics include a low annual rainfall, soil's susceptibility to wind erosion etc.
Based on these characteristics, an organism that will thrive in this biome must be structurally adapted to it. This is the case of the Turkey feet grass mentioned in the question. The Turkey feet grass possess very deep roots to prevent soil loss in windy areas, and to help anchor the plant. This is as a result of soil loss common to the soil of grassland biomes.
