Explanation:
Like all enzymes, a restriction enzyme works by shape-to-shape matching. When it comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the DNA molecule.

Explanation:
When two organisms are in a mutualistic relationship, they benefit each other in a way that both rely on each other for survival in a particular environment. The elimination of one of them might have a negative effect on the survival of the other.
So also, the development of new resorts in the area which leads to the detsruction of the Hawaiian silverswords will therefore have a negative effect on the population of the honeycreeper. The population of the Honeycreeper will decrease because they rely on the silverswords for survival.
Metagenomics (check all that apply): Group of answer choices Can leverage Next Generation Sequencing technology to identify and characterize organisms. Rarely finds previously unknown microorganisms. Has resources to support analysis at the DOE-JGI site. Can identify microbiologic organisms without traditional isolation and culturing of individual organisms.
Answer:
- Can leverage Next Generation Sequencing technology to identify and characterize organisms
- Has resources to support analysis at the DOE-JGI site.
- Can identify microbiologic organisms without traditional isolation and culturing of individual organisms.
Explanation:
Metagenomics can be defined as the study of whole genomes of biological communities recovered from environmental samples. This genomic field has enabled the discovery of new species (microorganisms) and their effects on the environment. Next-Generation Sequencing (NGS) technologies allow to obtain huge amounts of genomic data, which has been a limitation in genomics and metagenomics. Metagenomic NGS (mNGS) is a technique used for sequencing nucleic acids present in a biological sample containing mixed populations of microorganisms. Finally, the Department of Energy Joint Genome Institute (DOE JGI) is a referent in metagenomic analysis, especially in genome assembly data obtained from microbial communities. This Science User Facility has developed a series of bioinformatics tools and databases in order to analyze metagenomic information.

Explanation:
explain how fossils could be used as evidence of evolution
Answer: Fossils are like biological documents. They prove the existence of species that are now extinct (like dinosaurs). They also show how different organisms that once lived on Earth lived, survived, and acted during different periods of the Earth's ancient, and even more recent history. Fossils can also help scientists and biologists reconstruct the evolutionary histories of present-day species.
Explanation: I hope this helps! Here's a picture of a species' fossils showing the species evolving over millions of years. ( I think it's a horse)

what might happen to cause biologists to modify the cell theory?
Answer:
Rudolf Virchow modified the cell theory and gave the concept of 'Omnis cellule e cellulae'- which means new cells develop by the division of the pre-existing cells. This is called the theory of cell lineage or common ancestry.
Explanation:
Based on their studies on cells, Schleiden and Schwann together formulated the cell theory. This theory however, did not explain as to how new cells were formed. Rudolf Virchow (1855) first explained that cells divide and new cells are formed from pre-existing cells (Omnis cellula-e-cellula). He modified the hypothesis of Schleiden and Schwann to give the cell theory a final shape. Cell theory as understood today is: (i) all living organisms are composed of cells and products of cells. (ii) all cells arise from pre-existing cells.
So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'

Explanation:
The factors that contribute to Mercury's daily temperature fluctuation of about 600°C
are the planet's slow rotation and
A. its close proximity to the sun.
B. its dense atmosphere.
C. its heavy, rocky, water-less terrain
D. the absence of a thick atmospheric layer to regulate temperature.
Answer:
D. the absence of a thick atmospheric layer to regulate temperature.
Explanation:
Mercury is the smallest and closest planet to the Sun. On its surface, Mercury's temperatures are extreme, reaching up to 600 ºC in the daytime and dropping to around -180 °C in the nighttime. This huge variation in Mercury's surface temperatures is due to the fact that this planet doesn't have an atmosphere to retain the heat at the night. Therefore, the heat during sunlight hours cannot be distributed on the surface of this planet, and temperatures at the poles can be hundreds of degrees below zero.

Answer this asap..........
Answer:
The answer is (d) (iv) and (v).
Explanation:
Soil bacterium Bacillus thruingiensis (Bt) produces proteins that kill certain insects like lepidopterans (tobacco dudworm, armyworm), coleopterans (beetles) and dipterans (flies, mosquitoes). Bacillus thuringinesis forms some intracellular protein crystals. These crystals contain a toxic insecticidal protein. The Bt toxin protein exists as an inactive toxin and is converted into an active form due to the alkaline pH of the alimentary canal that solubilities the crystals. The activated toxin binds to the surface of midgut epithelial cells and creates pores which cause cell swelling and lysis and finally cause the death of the insect.
So, the correct answer is '(iv) and (v)'.

Okkkkkkk
Explanation:
Don't see why your asking a question even though your not asking a question because you're just giving an answer but doing it as a question
Answer:
A codominance
Explanation:
Thanks to the field of linguistics we know much about the development of the 5,000 plus languages in existence today. We can describe their grammar and pronunciation and see how their spoken and written forms have changed over time. For example, we understand the origins of the Indo-European group of languages, which includes Norwegian, Hindi and English, and can trace them back to tribes in eastern Europe in about 3000 BC.
So, we have mapped out a great deal of the history of language, but there are still areas we know little about. Experts are beginning to look to the field of evolutionary biology to find out how the human species developed to be able to use language. So far, there are far more questions and half-theories than answers.
Find in this text 6 noun and 6 adverd and 6 adjectives and 6 noun phrase and 6 Adverbial clause
We know that human language is far more complex than that of even our nearest and most intelligent relatives like chimpanzees. We can express complex thoughts, convey subtle emotions and communicate about abstract concepts such as past and future. And we do this following a set of structural rules, known as grammar. Do only humans use an innate system of rules to govern the order of words? Perhaps not, as some research may suggest dolphins share this capability because they are able to recognise when these rules are broken.

1. Why does population growth slow as size increases in the logistic model?
A due to a decrease in death rate
B due to an increase in birth rate
C due to density-independent factors
D due to density-dependent factors
The population growth slows as size increases in the logistic model due to the density independent factors.
What are density dependent factors?A density-dependent factor is any force that modifies the size of a population of living creatures in reaction to the population's density. Disease, competition, and predation are examples of factors that depend on density.
What are density independent factors?An element that has an impact on population size regardless of population density.
These density-independent factors consist of nutrient or dietary restriction, environmental contaminants, and harsh weather.
What is logistic growth?In logistic growth, a population's rate of per capita growth declines as it approaches the carrying capacity, a limit imposed by the environment's limited resources.
How does the population change over time?The variation in fundamental processes like natality, or the birth rate, mortality, or the death rate, as well as immigration and emigration, affects the population density in a particular ecosystem.

Explanation:
Histone proteins are among the most highly conserved protein in eukaryotes. Histone H4 proteins from a pea and a cow, for example, differ in only 2 of 102 amino acids. However, comparison of the two gene (nucleotide) sequences shows many more differences. These observations indicate that mutations that change amino acids must be selected against.
Required:
Why do you suppose that amino acid-altering mutations in histone genes are deleterious?
Answer:
nucleosomal histones (H2A, H2B, H3 and H4) strongly interact among them and with DNA in order to form nucleosomes. In consequence, it is expected that mutations in histone genes have deleterious effects on the organization of the chromatin
Explanation:
Nucleosomes are well known to be the basic structural units of DNA packaging in eukaryotic cells. Each nucleosome consists of an octamer of histone proteins, i.e., two copies each of the histones H2A, H2B, H3, and H4, and one segment of DNA wrapped around this octamer of histones. Chromatin organization is fundamental o regulate key cellular processes, including gene expression and genome maintenance. In consequence, it is expected that histone proteins are evolutionary well conserved across the eukaryotic kingdom.
True or False: All systems interact to ensure the body maintains homeostasis.
