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.

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.

what is the biggest change in leg anatomy that occurred from the dawn horse to the modern horse?
Answer:
The modern horse, in addition to having much longer legs, has developed hooves in place of hand/foot bones.
Explanation:
The modern horse, in addition to having much longer legs, has developed hooves in place of hand/foot bones.
What are the characteristic of modern horse?The modern horse, Equus caballus, became widespread from central Asia to most of Europe. Local types of horses, all breeds of this single species, undoubtedly developed, and three of these—Przewalski's horse.
According to a study published in Nature on 20 October1, modern domestic horses probably originated on the steppes around the Volga and Don rivers, now part of Russia, before spreading across Eurasia, ultimately replacing all pre-existing horse lineages.
Living members of the family Equidae all belong to one genus, Equus. That genus includes donkeys, zebras, Przewalski's horses, and all the many breeds of domestic horses, Equus caballus, such as the mustangs of the American West and Andalusians of Spain.

Guys I need help ASAP
Answer:
D.
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.

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.

What are volcanoes?A volcano has a hill or mountain or it has an opening in a planet or moon's crust from which molten rock, warm gases, and materials erupt. It has a landform where molten rocks erupt through the surface of the planet and volcano moutains open downwards to molten rocks.
According to Geologists there's are four types of the volcanoes and these are lava domes, shield volcanoes, composite volcanoes, and cinder cones.
The main reason behind the formation of volcanoes are movement of tectonic plates it means when one tectonic plate moves under another tectonic plate volcano has formed.
Therefore, The surface of the moon to look the way it does because on Earth point of view, then it is sunlight reflecting off of its surface. If you mean on the moon point of view, then it is because the moon has impact craters and dead volcanoes all over it.
