Read the information below. You just scratched a mineral sample with your fingernail. Your fingernail measures 2.5 on the Mohs scale and fluorite measures 4 on the Mohs scale. Explain why the mineral sample you have cannot be a piece of fluorite
Please help me I need to write a 3 sentence​

Answers

Answer 1

Answer:

It can't be fluorite because your fingernail is less on the Mohs scale than fluorite. When an object is less than another object on the Mohs scale it doesn't leave a scratch on the other object. Therefore if your finger leaves a scratch on the material then it has to be less than 2.5 on the Mohs scale. Fluorrite is not less than 2.5 on the Mohs scale so it is impossible that it is that mineral.

If a female is heterozygous for an X-linked allele, how many types of gametes can she produce with respect to that allele?

Answers

Answer:

Two (2)

Explanation:

If a female is heterozygous for an X-linked allele, such a female can produce two different gametes with respect to the allele.

Being heterozygous means that there are two different alleles representing the gene. The first gamete produced by such female would carry the dominant allele while the other gamete would carry the recessive allele.

**Urgent** Will mark brainliest!

Answers

Answer:

Although these two animals are both bears, clearly they are entirely different. Becasue they live in pretty much opposite environments, they developed individual traits so they could survive, which is called adaption. While the polar bear's thick fur and fat serve as great protection against the cold, it wouldn't be very helpful in hot climates. And the sun bear, with it's short hair and lack of protection, would freeze to death in the polar bear's environment. Each animal, over time, has to develop new traits that allow it to adapt to it's particular environment.

Answer:

These 2 different types of polar bears, may be the same type of animal, but as given in that text, they differ. These 2 different types of polar bears have different types of survival skills, in order to adapt to their environment. The Polar bear in the Northern Hemisphere has very thick fur, and other thick parts in it's body to keep them warm in the ice-covered areas that it lives in so that it wont die, due to the cold. While on the contrary, the bear in the tropical rainforest only has short hair, to keep them at a just-right temperature, so it wont die due to how hot it is. If both of these bears were to switch their environment, then they will die easily since they are not well adapted to that environment.

describe what happens to DNA in the nucleus of the cell

Answers

Answer:

DNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes. The result is billions of new cells being created each day.

Imagine you lived in the late 1800s. How would your life be different? Identify some ways it might be better and some ways it might be worse. Why? *

Answers

Answer:

if i lived in the 1800s I think would have more free time because i wouldn't be on electronics all the time. I might not have an education because times were hard then and many kids had to work in factories like their parents to support the family. I could get sicker easier because there weren't many health codes back then and lining conditions weren't teh best

Answer:

Life could be better because it would be simpler, but sickness, poverty, and so many other factors could change it for the worse. The assassination of Abe Lincoln, the Austro-Prussian war, Early prohibition, and Billy the Kid could be some negative factors. On the other hand, so many new things were being invented, such as using coal for energy, matches, batteries, and so many other influential things.

Answers

To deplete freshwater consumption of the water must be greater than the renewal rate. If the precipitation collected it does not mean it depleted, it can be still used later on. If precipitation relieves drought also doesn't mean water is gone, water would be still accessible by using wells and it is stored underwater.

Describe the discovery of the importance of DNA including descriptions of at least two experiments
that lead scientists to the knowledge we now have today.

Ah this is due in 40 minutes :,)

Answers

Explanation:

Introduction

Our modern understanding of DNA role in heredity has led to a variety of practical applications, including forensic analysis, paternity testing, and genetic screening. Thanks to these wide-ranging uses, today many people have at least a basic awareness of DNA.

It may be surprising, then, to realize that less than a century ago, even the best-educated members of the scientific community did not know that DNA was the hereditary material!

In this article, we'll look at some of the classic experiments that led to the identification of DNA as the carrier of genetic information.

Protein vs. DNA

The work of Gregor Mendel showed that traits (such as flower colors in pea plants) were not inherited directly, but rather, were specified by genes passed on from parents to offspring. The work of additional scientists around the turn of the 20th century, including Theodor Bovari, Walter Sutton, and Thomas Hunt Morgan, established that Mendel's heritable factors were most likely carried on chromosomes.

Scientists first thought that proteins, which are found in chromosomes along with DNA, would turn out to be the sought-after genetic material. Proteins were known to have diverse amino acid sequences, while DNA was thought to be a boring, repetitive polymer, due in part to an incorrect (but popular) model of its structure and composition1

start superscript, 1, end superscript.

Today, we know that DNA is not actually repetitive and can carry large amounts of information, as discussed further in the article on discovery of DNA structure. But how did scientists first come to realize that "boring" DNA might actually be the genetic material?

Fall of the House of Usher, excerptBy Edgar Allan PoeUpon my entrance, Usher rose from a sofa on which he had been lying at full length, and greeted me with a vivaciouswarmth which had much in it, I at first thought, of an overdone cordiality of the constrained effort of the ennuyl manthe world. A glance, however, at his countenance convinced me of his perfect sincerity. We sat down; and for somemoments, while he spoke not, I gazed upon him with a feeling half of pity, half of awe. Surely, man had never before soterribly altered, in so brief a period, as had Roderick Usher! It was with difficulty that I could bring myself to admit theidentity of the wan being before me with the companion of my early boyhood. Yet the character of his face had been attimes remarkable. A cadaverousness of complexion; an eye large, liquid, and luminous beyond comparison; lipssomewhat thin and very pallid, but of a surpassingly beautiful curve; a nose of a delicate Hebrew model, but with abreadth of nostri unusual in similar formations; a finely moulded chin, speaking, in its want of prominence of a want ofmoral energy, hair of a more than web-like softness and tenuity; - these features, with an inordinate expansion above thregions of the temple, made up altogether a countenance not easily to be forgotten. And now in the mere exaggerationthe prevailing character of these features, and of the expression they were wont to convey, lay so much of change thatdoubted to whom I spoke. The now ghastly pallor of the skin, and the now miraculous lustre of the eye, above all thingsstartled and even awed me.
