Answer:
A. Cell differentiation produces cells with different gene expressions.
which of the following is not a difference between DNA and RNA ?
Group of answer choices
they have different phosphate groups in their backbones
They have different sugars in their backbones
DNA is a double strand and RNA is a single strand
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.
Therefore, Option A is correct. DNA and RNA have the same phosphate groups in their backbones.

A lot of your personality comes from ______________________ rather than your DNA.

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.

Which of the following phrases describe the function of the digestive system?
l. Smooth, muscular tube connects the mouth to the stomach
ll. Muscular action in the esophagus pushed food to the stomach
lll. Structures called the microvilli to increase the surface area of the intestines
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:
B. ll and lll
Explanation:
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.
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.

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.
Gather each and every fluid that had already leaked from the blood vessels.Start by removing anything foreign materials from the lymphatic system.Learn more about vessels here:

Answer:
A tall, green plant with dominant alleles for both characteristics have a genotype TTGG and its phenotype is tall and green.
Explanation:
For a given trait, the dominant allele of the allelic pair is represented in capital letters (T and G), while the recessive allele is represented in small letters (t and g).
In the case of this plant, whose phenotype is tall and green —both dominant characteristics— and considered pure because both alleles are dominant, the genotype is TTGG.
In the case of a hybrid, the phenotype would be the same but the genotype would be TtGg. A recessive phenotype would be ttgg.PLEASE HELP ME!!!! :)
What similarities and differences do you notice among the two types of metabolic reactions (dehydration synthesis & hydrolysis)?
Answer:
In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.

What are some characteristics that protists and fungi both have that make them eukaryotes?
Answer:
They have a nucleus and other membrane bound organelles.
Explanation:
hoped this helped :)
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

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.
