Nabeel is trying to determine whether the slope of the ground affects the growth rates of plants. He just finished taking measurements of plant heights in various locations over a period of time. Now, he is starting to compare his measurements and look for patterns. Which step of the scientific method is Nabeel on?
Answer:
Experiment
Explanation:
Scientific methods includes the step by step procedures in science of solving problems.
It has four basic steps this include, Characterizations which is the observations, definitions, and measurements of the subject that is involved in the research.
Hypotheses is formulated which is the theoretical explanations of the problems to be solved.
Predictions are made from the hypothesis formulated and
Experiments which is done to validate the hypothesis. It includes DAT collection, data analysis, interpretation of results. Nabeel is at the experiment stage where he is collecting data on plant and comparing the data so he can make inference that can help validate his hypothesis.
The diagram for this question is missing, but I'll try to solve it nonetheless, for PLATO users. I do believe the answer is Test the hypothesis with an investigation, at least when thinking of the guy up above me's answer....
Explain mendel's experiment with peas on inheritence of characters considering only one visible contrasting character.
Ples answer in making points, it is for 5 marks.
➜ Mendel conducted breeding experiments with garden peas:
[i] He studied plants (pure) of a tall/short varities.
[ii] He crossed them and obtained F1 progeny.
[iii] He found that F1 progeny was all tall plants.
[iv] He selfed the (hybrid) plants if F1 progeny.
[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.
(or any other contrasting character may be taken).
Note: Here, F1 means First fillial generation and F2 means Second fillial generation.
Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. ... Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants...We used to take this character, we may choose different.

According to Darwin's theory of evolution, what causes a struggle for survival in
populations?
Answer:
In a population, more individuals are born than can survive. The available resources in nature are finite (food, water, space, etc.) and the environment is not able to support unlimited growth of a population. This causes an inevitable struggle for existence among individuals (continual struggle for existence).

What is used to regulate gas intake and output with a plant?
Answer-
The plants stomata!
Stomata regulate transpiration and CO2 intake by changing its size depending on the environmental signals. In optimum conditions, stomata are wide open, allowing gaseous exchange with the atmosphere.
What data provides the strongest evidence (most valid) that early Earth conditions provided what was necessary for life?
A- Fossil evidence showing that prokaryotic cells required an environment free of oxygen.
B- Genetic comparisons revealing that living and extinct organisms share commonalities.
C- Geological dating techniques supporting theories regarding Earth's age.
D- Geological studies proving that volcanic gases resemble those from early Earth.
Answer:
A - Fossil Evidence showing that prokaryotic cells required an environment free of oxygen.
Explanation:
Thanks OP for answering your own question!
The data that provides the strongest evidence (that is, the most valid evidence) that early Earth conditions provided what was necessary for life is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.
What are genetic comparisons in evolution?Genetic comparisons are the most direct and reliable source of evidence supporting the theory of common ancestry and the origin of life on Earth. All living organisms share a common set of genetic building blocks, such as DNA and RNA, and use the same genetic code to translate this information into the proteins that make up living organisms. Genetic comparisons reveal similarities between living organisms and extinct organisms, such as ancient bacteria and archaea, which provides further evidence for the common ancestry of all life on Earth.
Hence, it is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

A cell with only one set of chromosomes is called [ diploid or haploid ] cell.
Answer:
A cell with only one set of chromosomes is called a haploid cell.
compare and contrast the processes of mitosis (asexual reproduction) and meiosis (sexual reproduction).
Answer:
Diffrence:
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. parent. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

Explanation:
Lungs in humans and many other species branch out into many tubes until they end in small sacks called alveoli. These alveoli allow oxygen to enter the blood through the capillary beds as pictured above. Alveoli provide much more surface area for the lungs to contact the capillary beds. What is the advantage of lungs with alveoli compared to lungs without alveoli?
Answer:
It provides more surface area for the absorption of oxygen.
Explanation:
The advantage of lungs with alveoli compared to lungs without alveoli is the availability of large surface area for the oxygen absorption. Alveoli allows oxygen from the air to pass into your blood. There are 480 million alveoli are present in human lungs, this large number and small size of alveoli provides lungs a large surface area to volume ratio so we can conclude that the lungs work better with the help of alveoli as instead of lungs without alveoli.
