Explanation:
A ball bounces on the ground. How do the ball and the ground act on each other?
Explanation:
It will continue to fall under the influence of gravitational acceleration, but now, a normal force from the ground surface, opposing the force due to gravity, will act on the ball.This all means that the ball is pushing on the ground with a force greater than its own weight, so acceleration must point upward.
A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
(photo above)
Answer:
From the diagram X = base pairs
Explanation:
Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.
Nucleotides comprise:
a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides Thymine and Cytosine (pyrimidine bases) along with Guanine, and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.
How do Limiting factors affect biotic potential? Please hurry and help me
Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.

Identify one organism, one population, and one community
Answer:
The study of organisms, populations and communities examines how organisms interact with each other and their environment at individual, population and community levels. To characterize these interactions, NEON quantifies and observes interactions among multiple organisms and their environments. By sampling a variety of organisms in aquatic and terrestrial systems, NEON provides data on individual traits, population dynamics and the composition of communities. Integrated with other data collected across NEON sites, the project produces data in the areas of biodiversity, infectious diseases and invasive species.

Which statement illustrates bias in scientific research?(1 point)
A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.
B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.
C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.
D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.
Answer:
D
Explanation:
The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)
In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:
The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interestScientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.
According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.

What is the function of the valves in the lymphatic vessels?
Answer:
1. pick up any fluid that has escaped the blood vessels
2. return the escaped fluid to the heart
3. remove any foreign material from the lymph
Explanation:
Lymph vessels pick up any fluid that has escaped the blood vessels and return it to the heart. Lymph nodes remove any foreign material from the lymph (bacteria, viruses, tumors) and contain lymphocytes (WBC!!!)
Each and every fluid that had already exited the blood arteries is collected by lymphatic vessels as well as returned towards the heart. Lymph nodules filter out foreign particles from either the lymph as well as house lymphocytes.

The process of forming ATP is? A) Digestion. B) Cellular Respiration. C) Metabolism. D) nutrition.
Answer:
[tex]\boxed {\boxed {\sf B. \ Cellular \ respiration}}[/tex]
Explanation:
First, let's analyze each process.
A. Digestion
This is the process of breaking down food.
B. Cellular respiration
This is the process of converting glucose and oxygen to carbon dioxide, water, and ATP.
C. Metabolism
This isn't really a process. It's the collection of all the chemical reactions in the body to keep the body functioning.
D. Nutrition
This term also isn't a process. Nutrition involves food, nutrients, and health.
We are looking for the process that forms ATP. Therefore, the best answer choice is B. Cellular respiration
The process of forming ATP is Cellular Respiration. Therefore option B is correct.
The process of forming ATP (Adenosine Triphosphate) is primarily through Cellular Respiration.
ATP is the main energy currency in cells, providing the energy needed for various cellular activities.
Cellular respiration is a series of metabolic reactions that occur in the mitochondria of cells, where organic molecules (such as glucose) are broken down and oxidized to release energy.
This energy is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate (Pi).
Through cellular respiration, cells efficiently convert the energy stored in food molecules into a readily usable form of energy (ATP).
Which powers essential cellular processes, including muscle contraction, active transport, and synthesis of macromolecules.
Therefore option B Cellular Respiration is correct.

2. How are the kelp and the chemosynthetic bacteria of the
hydrothermal vents similar?
A. Both use energy from the sun to make food.
B. Both are primary producers.
C. Both are scavengers.
D. Both use hydrogen sulfide as an energy source.
Answer:
C. Both are primary producers.(THIS IS THE CORRECT ANSWER)
Explanation:
Chemosynthesis is a biological conversion of carbon molecules. These are found around the hydrothermal vents.
It is due to the bacteria feeds on the hydrogen sulfide that is coming out from the vents that are required as an energy tonic for the bacteria to survive and kelp also has similar requirements. Kelps forests are shelters for these bacteria and hence both are found near the source of energy.Hence the option B both are primary producers.

The characteristics that protists and fungi both have that make them eukaryotes is the possession of a membrane bound nucleus and other organelles.
EUKARYOTES:
Eukaryotic cells are cells that possess a membrane-bound nucleus to house their genetic material (DNA). Eukaryotes also possess other membrane bound organelles like mitochondria, golgi apparatus etc. This feature particularly differentiates them from prokaryotic cells. Eukaryotic organisms include plants, animals, fungi, some protists etc. Therefore, it can be said that the possession of a membrane bound nucleus and other organelles is the characteristics that makes fungi and protists be considered eukaryotes.Learn more: https://brainly.com/question/21196976?referrer=searchResults

lV. Nutrients are made available to the body's cells
A. l and ll
B. ll and lll
C. ll and lV
D. lll and lV
Answer:

The question above is asking for the "function" of the Digestive System. Function refers to how the digestive system actually works.
I is not related to the function of the digestive system. It only describes the "esophagus."
II is called the "Peristalsis." This is one of the functions of the digestive system. This allows the food to move down the GI tract.
III is part of the process called "Segmentation." This is one of the functions of the digestive system. The increase surface area of the microvilli expands 25 times and this allows greater absorption of food.
IV is not related to the function of the digestive system.

RNA replaces thymine with uricel
Answer:
I believe the answer is:
They both have different phosphate groups in their backbones
Option A is correct. DNA and RNA have the same phosphate groups in their backbones.
DNA is deoxyribonucleic acid. DNA contains deoxyribose sugar. DNA is usually found in double strands. In DNA thymine is present.
RNA is ribonucleic acid. RNA contains ribose sugar. RNA is usually found in single strands. In RNA thymine is replaced by Uracil.
Nucleic acid is made up of phosphate group, ribose sugar, and nitrogenous bases.
Hence, options B, C, and D are incorrect.
