Answers
The set of ecological organization levels that is most likely to contain the largest variety of species is: multiple biomes in a biosphere.
LEVEL OF ECOLOGICAL ORGANIZATION:
Ecology refers to the study of plants and animals (biotic) in relation to their environment. The level of organization in an ecological setup involves an hierarchical build up. The level of organization in ecology from the least to the highest is as follows: individual species → population → community → ecosystem → biome → biosphere. As the level increases, the more the species contained. This means that a community will contain more species than a population. Therefore, the largest variety of species is most likely to be found in the highest level of organization, which is multiple biomes in a biosphere.Learn more at: https://brainly.com/question/18536684?referrer=searchResults

In eukaryotic cells the default position of most genes is 'off', (they're not expressed). Explain why?
Answers
As a result of histones covering the majority of the DNA and thus preventing RNA polymerase interaction, most genes in eukaryotic cells are typically in the "off" state by default.
What is the cause of abnormal histones?Because the histones largely cover the DNA and block the polymerase and RNA binding, the transcriptional state of eukaryotic genes is off by default. The most prevalent protein in a cell is histones. They are in charge of the complex of DNA and proteins known as chromatin's creation. In eukaryotes, the histone proteins serve a variety of purposes, including cell division and development.
How do eukaryotic genes work?The proteins known as histones are in charge of keeping RNA polymerase from interacting with DNA. All eukaryotic cells are constructed from eukaryotic genes. They are in charge of a cell's whole life cycle and everything that takes place inside of it. They are in charge of transcription of lengthy nucleotide chains in DNA.

RNA does not function as the genetic material in the IIIS cells (Diplococcus pneumoniae)
Answers
The experiment carried out by Avery, MacLeod, and McCarty in 1944 established that DNA is the genetic material that carries genetic information. This experiment was conducted on the bacterium Streptococcus pneumoniae, which is a pathogen that causes pneumonia in humans.
This bacterium can exist in two forms, a rough strain and a smooth strain. The S strain is surrounded by a polysaccharide capsule, while the R strain does not have a capsule. When mice were injected with the S strain, they developed pneumonia and died.
On the other hand, the mice injected with the R strain were healthy.The researchers used enzymes to degrade proteins, RNA, and DNA from the heat-killed S strain. They then added the three enzymes to the living R strain and found that the transformation still occurred, indicating that none of the enzymes destroyed the transforming ability.
They then repeated the experiment with different enzyme combinations and found that when DNase was added to the living R strain, the transformation did not occur. This finding led them to conclude that DNA is the genetic material that carries genetic information.
Therefore, the fact that the transforming capacity of the IIIS cell extract was not abolished by treatment with RNase proves that RNA does not function as the genetic material in the IIIS cells (Diplococcus pneumoniae). Hence, option (D) is the correct answer.
This experiment provided important evidence that DNA is the genetic material that carries genetic information and paved the way for future genetic research.

a. $4,700
b. $5,590
c. $3,600
d. $2,390
e. $1,500
Answers
The net working capital for the firm is $1,500, calculated by subtracting current liabilities from current assets, the correct option is (e).
To calculate the net working capital, you need to subtract the current liabilities from the current assets.
In a company's financial statements, the formula for calculating current assets can be expressed as the sum of inventory, accounts receivable, and cash.
Current Assets = Inventory + Accounts Receivable + Cash
Current Liabilities = Accounts Payable
Using the given values:
Current Assets = $820 (Inventory) + $1,210 (Accounts Receivable) + $360 (Cash)
= $2,390
Current Liabilities = $890 (Accounts Payable)
The formula to calculate Net Working Capital is derived by subtracting Current Liabilities from Current Assets.
Net Working Capital = Current Assets - Current Liabilities
Net Working Capital = $2,390 - $890
= $1,500
Therefore, the amount of net working capital is $1,500.
Hence, the correct option is (e).

During digestion, nutrients are absorbed across the wall of the small intestine into your blood stream. Explain why the long length (20 ft.) and numerous finger-like projections along the internal surface of the small intestine serve to optimize this important functions.
Answers
During digestion, nutrients are absorbed across the wall of the small intestine into your bloodstream. The long length (20 ft.) and numerous finger-like projections along the internal surface helps in Absorption of Nutrients, Secretion of Enzymes and Digestive Juices and provides time for Absorption.
The long length and numerous finger-like projections along the internal surface of the small intestine serve to optimize this important function in several ways. The small intestine is approximately 20 feet long and is divided into three parts, each with a distinct function.
The finger-like projections are called villi, and they are made up of tiny hair-like structures called microvilli. These villi and microvilli together form a large surface area on the internal surface of the small intestine which is responsible for the absorption of nutrients.
There are several reasons why this large surface area is important:
1. Absorption of Nutrients: The large surface area created by the villi and microvilli maximizes the amount of nutrients that can be absorbed across the intestinal wall into the bloodstream. This is because the surface area of the small intestine is directly proportional to the rate of nutrient absorption.
2. Secretion of Enzymes and Digestive Juices: The long length of the small intestine allows for the secretion of enzymes and digestive juices that help to break down food and aid in the absorption of nutrients.
3. Time for Absorption: The length of the small intestine also allows for enough time for the absorption of nutrients before the food waste reaches the large intestine.
This is important because the large intestine is primarily responsible for the absorption of water from waste material, so it needs to be kept as dry as possible to prevent dehydration.

2. Why is there a variation in the base that adenine pairs with in DNA and RNA?
Answers
Answer:
However, the “bases” of RNA differ from those of DNA in that thymine (T) is replaced by uracil (U) in RNA. DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).
The variation in the base that adenine pairs with in DNA and RNA is due to the chemical properties of the nucleotide bases and their ability to form hydrogen bonds with other bases.
What are nucleotides?Nucleotides are the building blocks of nucleic acids, which include DNA and RNA, and play a critical role in the storage and transmission of genetic information in living organisms. A nucleotide consists of three components: a nitrogenous base, a five-carbon sugar, and a phosphate group.
There are four types of nitrogenous bases in DNA: adenine, thymine, guanine, and cytosine. In RNA, uracil replaces thymine. The nitrogenous base, sugar, and phosphate group combine to form a nucleotide, and these nucleotides join together through covalent bonds between the sugar and phosphate groups to form long chains of nucleic acids.
The specific sequence of nucleotides in DNA and RNA provides the genetic code that determines an organism's traits and characteristics.

describe the role of polycomb group proteins in maintaining gene
repression?
Answers
Polycomb group proteins are a group of gene-regulating proteins that have been conserved in evolution and play important roles in development and cell differentiation.
They are essential for the maintenance of gene repression. The role of Polycomb group proteins in maintaining gene repression is as follows:
Polycomb group proteins control the transcriptional activity of genes by regulating chromatin structure, which is crucial for gene expression. They do this by modifying the histones that make up the nucleosomes in chromatin, which in turn affects the accessibility of the DNA to the transcriptional machinery.
In particular, the Polycomb group proteins catalyze the methylation of histone H3 on lysine 27, which leads to the recruitment of other repressive proteins that maintain the chromatin in a compact, inactive state.In addition, Polycomb group proteins also function in higher-order chromatin organization. They help to organize chromatin into higher-order structures, such as loops and domains, which can have important effects on gene expression.
This is achieved through the recruitment of other proteins, such as insulator proteins, which help to establish boundaries between different chromatin domains. In summary, Polycomb group proteins are critical for the maintenance of gene repression by regulating chromatin structure and higher-order chromatin organization.
