human cells normally have 46 chromosomes. let us define the transition from one cell to two cells as meiosis i proceeds. what is the number of nuclear dna molecules present in the human cells formed at the completion of meiosis i?
After the completion of meiosis-I there are 2 DNA molecules present in the human cells.
How many DNA molecules are present in nucleus of human cells after meiosis-I?There are generally 46 chromosomes in each human cell. Now there are 4 sub-phases under meiosis-I i.e. prophase-I, metaphase-I, anaphase-I and telophase-I. During prophase-I and metaphase-I there is the formation of tetrad in a chromosome which means that there are 4 chromatids or 4 DNA molecules. But during metaphase-II which is a sub-phase of meiosis-II the number of chromatids is reduced into 2 which means that there are only 2 DNA molecules now.
So, there are only 2 nuclear DNA molecules after the completion of meiosis-I.

An estimated 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct. This extinction was caused by a combination of factors, including massive volcanic eruptions, climate change, and a possible impact event. The Permian extinction had a profound impact on the evolution of life on Earth, clearing the way for the rise of the dinosaurs and the eventual domination of mammals.

what is a characteristic of eudicots? parallel leaf venation a flower with six petals vascular bundles scattered throughout the stem a taproot system
A taproot system is a characteristic of eudicots.
Therefore, correct answer is E) a taproot system.
'What are eudicots?'
About 190,000 identified species, or 75% of all angiosperms, belong to the vast, monophyletic group of angiosperms known as the eudicots. A tricolpate or pollen grain formed from a tricolpate serves as the boundary between the monophyly of eudicots, which is strongly supported by molecular data.
Three equally spaced openings, roughly parallel to the polar axis of the grain, define a tricolpate pollen grain. Differentiated areas of the pollen grain wall are called apertures, and they may serve as the location of the pollen tube exitus in addition to providing space for the pollen grain to expand and contract in response to changes in humidity.

why didn’t darwin use mendel’s results when formulating his theory of evolution by natural selection?
Darwin's focus on small quantitative variations as the raw material of evolution may have prevented him from discovering the laws of inheritance. Heredity and variation were two concepts that played a central role in Darwin's development of the theory of evolution by natural selection.
Natural selection is the variation in phenotypic variance-driven individual survival and reproduction. A key mechanism of evolution is the generational evolution of a population's heritable traits. Charles Darwin popularized the term "natural selection" by comparing it with artificial selection, which in his view is intentional while natural selection is not.

alcohol inhibits the release of antidiuretic hormone (adh, or vasopressin) from the posterior pituitary. determine why alcohol is a poor choice for rehydration when we are thirsty.
Alcohol is a bad choice for rehydrating when we are thirsty because it has antidiuretic properties that help with bladder water retention. Rehydrating while drinking alcohol causes frequent urination and ineffective liquid absorption.
Alcohol prevents the production of ADH. When the amount of ADH is lowered, the kidneys emit more fluid than they alternatively usually would and so we go to the bathroom more. The ADH signals your kidneys to continue to water. By restraining ADH, alcohol can create the kidneys to release more water.
Alcohol blocks the release of the antidiuretic birth control method in the kidneys. Normally this birth control method advances the kidneys to hold water in the material, but intoxicating blocks the birth control method by flushing water to the pouch. Alcohol restricts ADH (antidiuretic hormone) that is created in the hypothalamus and freed from the pituitary.

The type of epithelium found in areas likely to be subjected to abrasive activities and mechanical stress is a stratified epithelium.
Stratified epithelium is the term for a layer of tissues where squamous cells are stacked in multiple layers and the top layers are made up of dead cells covered in keratin (a protein). Stratified epithelium makes up the skin of the human body (or any mammal), the lining of the throat and buccal cavity, and the lining of the nasal cavity.
It is crucial to understand that the distinction between "nonkeratinized" and "keratinized" stratified squamous epithelium (SSE) does not lie in the presence or lack of keratin.

What evidence supports the impact hypothesis for the end-Cretaceous extinction?
The rock record contains a wealth of data that lend credence to this theory. Near Chicxulub, Mexico, a massive crater with a diameter of 180 km (112 miles) and dating to the end of the Cretaceous was found buried in sediments from the Yucatán Peninsula.
At Boltysh in Ukraine, a second, smaller crater that is between 2,000 and 5,000 years older than the one at Chicxulub was found in 2002. Its existence suggests that numerous bolide impacts may have caused the K-T extinction. The rare-earth element iridium, which is only found in great abundance in the Earth's mantle and in alien rocks, as well as tektites—fractured sand grains typical of meteorite impacts—have also been discovered in deposits linked to the extinction.
Despite this compelling evidence, the asteroid theory has encountered resistance from certain palaeontologists, who argue that terrestrial factors were to blame for the extinction and that a comet or smaller object may have contributed to the amount of iridium that was disseminated by the impact.
