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
Answers
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.
In aquatic ecosystems, phytoplankton and other photosynthetic organisms appear in the upper layer of the water, but not deeper layers. Which statement explains this distribution?
Answers
ANSWER :
The deeper layers are too dark for photosynthesis to occur.
Explanation:
Photosynthesis is a unique process to autotophic organisms. It involves the use of light energy from the sun to manufacture organic molecules (food). As the phenomenon implies i.e. PHOTO - LiGHT, light is an unnegotiable requirement for photosynthesis to take place. Autotrophs are able to perform this process because they contain pigments (Chlorophyll) that can trap energy from sunlight.
In an aquatic ecosystem, phytoplanktons and other photosynthetic organisms like aquatic plants are the autotophic organisms. They are found in the upper layer of the water so that they can reach light from the sun. The light from the sun cannot travel deep down the water making the deep parts of the ocean be deprived of light.
This is the reason why photosynthetic organisms cannot be found in the deep parts of the water as they will be unable to have access to the light from the sun in order to perform photosynthesis.

come from experimentation? Explain your
answer. SC.7.N.1.3
Answers
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.in atom structure what is present in the same numbers as the protons in an atom.i will make as brainlest

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.

Which of the following statements concerning ribosomes is true?
A. Several ribosomes are often attached to and translating the same MRNA.
B. Ribosomes join amino acids together to form a polypeptide.
C. Ribosomes have one binding site for MRNA and three binding sites for 1RNA molecules.
D. Ribosomes are the organelles responsible for protein synthesis.
E. All of the above statements are true.
Answers
Answer:
E. All of the above statements are
Explanation:
Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.
A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).
Ribosomes are complicated macro molecules composed up of nucleic acids and proteins. They are important as they perform a major role in protein assembly and transportation.
The correct answer is:
Option E. All of the above statements is true.
The explanation for the above option is:
The ribosome is located either free or is connected to the endoplasmic reticulum(RER).Ribosomes assist in the translation of the information from mRNA.Polysomes are numerous ribosomes connected to a single mRNA molecule.Ribosomes have one binding position for mRNA and three binding positions for tRNA molecules.The three binding sites for tRNA is (A- site) amino acyl site, (P-site) peptidyl site and (E site) the exit site.Ribosome assembles amino acids to form a polypeptide chain. These polypeptides get transported to the cytoplasm.Therefore all the above statements are true for ribosomes.

Nicholas has been biting his nails since he was a kid. He wants to break the habit so he puts bitter-tasting nail polish on his left hand and leaves his right hand without polish. After 3 days he notices his nails on his left hand have grown but he continued to bite his right-hand nails.
A. Independent Variable=
B. Dependent Variable=
C. Control=
Answers
Answer:
Independent: Putting the nail polish
Dependent: nail growth
Control: right hand, without polish
The experiments are known to have various variables. In Nicholas's case, nail polish is an independent variable, nail growth is a dependent, and right nails without polish are a control.
What are independent variables?Independent variables are defined as the test variables that in an experiment are not constant but are kept varied and manipulative causing various effects on the result of the hypothesis. Putting the bitter nail polish on the nails of the left hand is a test variable.
The dependent variable (outcome variables) along with independent results in cause and effect and are conditional on the independent factors. The length of nails is dependent as it is affected by the nail-biting.
On the other hand, the control variables are constant in that the factors are limited so that they do not interfere with other factors that affect the outcome. Fingernails on the right hand with no polish are controlled.
Therefore, nail polish is an independent variable.
