cells differentiate according to the chemical environment they are immediately exposed to.T/F
THYMUS. T-cell differentiation occurs within the thymus and is characterized by ordered expression of various CD surface molecules and V, D, and J gene rearrangements.
Gene expression alterations lead to cell differentiation. This happens when various environmental signalling molecules activate or repress certain transcription factors that are required for the expression of particular genes. Environmental variables can also affect cell differentiation and gene expression. For instance, temperature, salinity, and the amount of available nutrients may all affect how an organism's genes are expressed. The Himalayan rabbit's genes that control fur colour are activated and inactivated in response to temperature. Chemicals, extracellular proteins, hormones, and other substances, as well as signals from other cells and the physical environment, converge on the cell, often starting a signalling cascade that results in gene expression. These particular proteins alter the phenotypic to that of a cell that is more specialised.

thus far, there is agreement that all hominins found outside africa are members of which taxonomic group?
Thus far, there is agreement that all hominins found outside Africa are members of Homo taxonomic group.
A number of breathtaking Palaeontological finds have cast doubt on the conventional theory of human evolution and the manner in which early man colonized the globe. These findings imply that Africa was not the only place where humans first evolved.
A small number of prehistoric human skulls discovered by archaeologists two hours from Tbilisi, the capital of Georgia, point to a Eurasian phase in the lengthy history of human evolution.
The skulls, jawbones, and shards of limb bones show that our ancestors left Africa far earlier than previously believed, spent a significant amount of time in Eurasia, and then returned to Africa to finish the tale of man.The Dmanisi hominins are the first members of our own genus, Homo, to be found outside of Africa, and they currently make up the most primitive group of the Homo erectus species.

Which scientist developed the planetary model that stated electrons were found in specific energy levels around the nucleus?
Ernest Rutherford developed the planetary model that stated electrons were found in specific energy levels around the nucleus.
The Rutherford model, also known as the Rutherford atomic model, nuclear atom, or planetary model of the atom, is a description of the structure of atoms that was put out in 1911 by physicist Ernest Rutherford, who took birth in a city of New Zealand. According to the idea, an atom consists of a small, compact, positively charged core called a nucleus, which is where almost all of the mass is concentrated.
The light, negatively charged electrons then orbit the nucleus at a slight distance, much like planets orbit the Sun. Under the guidance of Rutherford and German physicist Hans Geiger in 1909, Ernest Marsden, a student, conducted a series of experiments that revealed the scattering of alpha particles from thin gold foil.
This resulted in the hypothesis that the nucleus was tiny and dense.

sexual selection in a population choose one: a. can lead to physical differences between the males and females of a species. b. does not lead to evolution. c. reduces genetic variation in the population. d. always favors individuals with a higher survival potential.
The right response is option a, which states that morphological distinctions between males and females of a species can result from sexual selection in a population.
The tail of a peacock is a good illustration of partner selection. Peahens choose peacocks with huge, vibrant tails, which allows those peacocks to mate more frequently and produce younger ones. The genes for a long, colourful tail will be passed down from the father to the male peachicks, who will inherit these genes and develop comparable tails. There are two main factors that influence sexual selection. One is the preference of one sex (typically females) for members of the opposite sex who display particular features. The other is higher strength, which (often in males) results in better success in courting females.
So, we can conclude that option a, which claims that sexual selection can lead to physical differences between males and females of a species in a population, is the appropriate response.

what is the viral envelope, and what does the presence (or absence) of it tell you about the type of virus?
The envelope, which is derived from the host cell membrane, surrounds the viral capsid and serves as just an additional barrier to a external environment. The vast majority of animal viruses are enveloped, whereas the vast majority of viruses that infect plants or bacteria are not.
The viral genome is packaged in a protein coat known as the capsid in virus particles. For some viruses, the capsid is surrounded by a lipid bilayer containing viral proteins, which typically include proteins that allow the virus to bind to host cells. The virus envelope is a lipid and protein structure derived from the host cell membranes. Viral genetic material is contained within protein structures known as capsids.
Viruses are classified into two types: enveloped viruses, which have an outer lipid membrane, and nonenveloped viruses, which do not. The envelope, when present, contains viral proteins that mediate binding to host cells. When there is no envelope, the outer capsid proteins perform this function. Nonenveloped viruses, in general, are more stable and can survive in the environment for much longer. The method of viral entry and exit from host cells is determined by capsids and envelopes.

Allele frequencies within a population can be altered by all except which of these processes?A. MigrationB. MutationC. Natural selectionD. Inbreeding
All except inbreeding can alter the allele frequencies within a population.
The Hardy-Weinberg theorem also describes populations in which allele frequencies are not shifting. Such populations are not evolving by definition. We can deduce the theorem's implications for what drives changes in allele frequencies. The "forces of evolution" are these variables. These four forces are natural selection, genetic drift, gene flow, and mutation. The "Natural Selection" concept will cover natural selection.
In a gene pool, mutation produces new genetic variation. All new alleles develop in this manner. The mutations that affect evolution in sexually reproducing organisms are those that take place in gametes. Individuals moving into or out of a population cause gene flow. Allele frequencies may be significantly impacted by a high migration rate. A small population's genetic drift is a random shift in allele frequency.
Hence, allele frequency is altered from mutation, gene flow and genetic drift.

if natural fires and herbivores can both reduce the abundance of competitively superior plants, how should this affect the number of other plant species that can persist in the community?
It can cause woody plants to proliferate and outcompete plants that have adapted to fire, reducing the number of plant species that can survive in the community.
Resources are often scarce in a habitat, and many species could compete for them. Plants in a garden, for example, may compete for soil nutrients, water, as well as light. Interspecific competition has a negative overall effect on both species involved. That is, if the other species did not exist, each species would fare better.
Interspecies competition occurs when two species compete for the same limited resource. Both species suffer as a result of competition.

Option B - Whenever roasting beef that contains a lot of collagen, To make gelatin, cook the collagen using a wet heat method.
At 160/70, collagen begins to break down into gelatin. The meat becomes dryer, but at 160F the collagen-containing connective tissues start to turn into gelatin. Muscle fibers that had been tightly bound start to easily stretch apart over time. The flesh appears more tender because of the succulence that the gelatins produce, despite the fact that the fibers are still very stiff and dry.
Therefore, we want our meat to be cooked tenderly so that the rough collagen is transformed into gelatin while minimizing moisture loss. The fact that these techniques conflict with one another is what makes cooking meat difficult or problematic. However, temperatures must be lower than 130F in order to avoid moisture loss.
