Since ancient time,people have been fascinated with the night sky.The night sky came aleve with bright objects that hinted at other worlds,but they were difficult to study with the naked eye.what instrument did scientists invent to study to study the different objects in the night sky
A)microscopes
B)electromagnética radiation
C)observatory
D)telescope
Answers
Final answer:
The telescope is the instrument scientists invented to study the night sky, enabling significant advancements in astronomy since its invention around 1600. It allows for greater magnification and resolution to observe previously unseen celestial bodies. Galileo was among the first to use it for such studies, leading to groundbreaking discoveries.
Explanation:
Scientists invented the telescope to study the different objects in the night sky. The telescope was created around 1600 and was pivotal in advancing our understanding of astronomy. It gathers more light than the human eye can, allowing us to see dim objects with greater magnification and better resolution. The Greeks and Romans laid the foundation of astronomy which was enhanced significantly with the invention of telescopes.
Before telescopes, ancient civilizations observed the night sky to keep track of time and seasons, giving names to patterns of stars known as constellations. These constellations still help astronomers today. Ancient observatories were sites dedicated to monitoring celestial objects but were limited to the human eye's capabilities. The invention of the telescope allowed for the observation of celestial bodies that were previously beyond our sight.
Famous astronomer Galileo was one of the first to use a telescope to study the heavens, leading to critical discoveries such as the moons of Jupiter and the intricate details of the Milky Way. Today, although the night sky has been obscured for many by artificial lighting, telescopes continue to play a crucial role in the exploration of the universe.

After the Aswan High Dam was built on the Nile River, the rate of parasitic blood-flukeinfection doubled in the human population near the dam. As a result of building the dam, the flow of the Nile changed. This changed the habitat, which resulted in an increase in its population of a certain aquatic snail. The snails, which were infected, released larvae of the fluke. These larvae then infected humans. This situation best illustrates that:
a.the influence of humans on a natural system is always negative in the long termb.the influence of humans on a natural system can have unpredictable negative impactsc.human alteration of an ecosystem does not need to be studied to avoid ecological disasterd.human alteration of an ecosystem will cause pollution and loss of finite resources
Answers
Answer:
b.the influence of humans on a natural system can have unpredictable negative impacts
Explanation:
The situation described best illustrated the fact that the disturbance of natural ecosystem by humans can have unpredictable negative impacts.
Option c is incorrect because human alteration of the ecosystem needs to be continuously studied to avoid ecological disasters.
Option d is incorrect because alteration of the ecosystem does not always end up in the pollution of the ecosystem and loss of finite resources.
While human alteration of the natural ecosystem often have long term negative impacts, many of these impacts can not be predicted until they happen. This makes option b to be more complete than option a.
The correct option is b.
The doubling of parasitic blood-fluke infections after the Aswan High Dam's construction illustrates that human impacts on natural systems can have unpredictable negative effects, altering habitats and increasing disease risks.
Explanation:After the Aswan High Dam was built on the Nile River, the rate of parasitic blood-fluke infection doubled in the human population near the dam. This increase in infection rates illustrates that the influence of humans on a natural system can have unpredictable negative impacts. Construction of the dam altered the river's flow, creating a new habitat that favored the proliferation of a particular aquatic snail species that harbored the parasitic fluke larvae. These larvae infected humans, showing that human alteration of an ecosystem has complex repercussions, affecting both the ecological balance and human health.
Dams impact the natural water habitat by altering temperatures, chemistry, flow characteristics, and silt loads. This can lead to extensive changes in the ecology, affecting a wide variety of species. Damming rivers, a common practice for human needs, can reduce or eliminate populations that rely on seasonal flow changes, such as certain fish and amphibian species. The case of the Aswan High Dam serves as an example of the unintended ecosystem and health implications of significant infrastructural projects.
n the United States and Canada, bats use one of two strategies to survive winter: They either migrate south, or they hibernate. Recently, those that hibernate seem to have come under attack by a fungus, Geomyces destructans (Gd), an attack that is occurring from Missouri to southern Canada. Many infected bats have a delicate, white filamentous mat on their muzzles, which is referred to as white-nose syndrome (WNS). The fungus invades the bat tissues, causes discomfort, and awakens the bat from its hibernation. The bat fidgets and wastes calories, using up its stored fat. The bat then behaves abnormally, leaving its cave during daytime in winter to search for food. Their food, primarily insects, is scarce during the winter, and the bats ultimately starve to death. Since 2007, it is estimated that up to one million bats have perished from WNS.
The Gd mat on the fur of the bats should be expected to consist of _____.
Answers
Answer:
Hyphae
Explanation:
It is given that the bat affected by fungus, Geomyces destructans (Gd) consists of delicate, white filamentous mat on their muzzles which could be possibly the hyphae.
It is so because the hyphae is made of cells having tubular cell walls which more or less look like internal cross-walls having large pores to absorb nutrients from the surrounding environment (i.e bat’s body) and transport them to thallus. Hyphae are basically long thread like structures that spread throughout their food and release enzymes that break down the food
The genetic code is essentially the same for all organisms. From this, one can logically assume all of the following EXCEPT: A) DNA was the first genetic material. B) All organisms have a common ancestor. C) A gene from an organism could theoretically be expressed by any other organism. D) Related organisms have many similar genes. E) All organisms must either manufacture nucleotides or obtain them from their environment.
Answers
Answer: DNA was the first genetic material.
Explanation:
The genetic code is essentially the same in all the organism. This states that the similar organism can have similar genes in them that codes for the similar proteins hence, called as similar organism.
The genetic material is chemically made of nucleotide which is either being synthesized in the body or being obtained from the environment similar to that of amino acids.
If the genetic code is same one organism descend from the other organism.But these statement does not supports that DNA was the first genetic material to found in living beings.
Although the genetic code is nearly universal across all organisms hinting at a common ancestry, such a fact cannot logically validate the claim that DNA was the first genetic material. The origins of life's first genetic material remain a subject of scientific debate, and this cannot be inferred from the universality of today's genetic code.
Explanation:The genetic code is nearly universal, shared among all organisms to some degree. This homologous characteristic implies shared common ancestry and suggests that virtually all organisms use the same genetic code for protein synthesis, which allows for genes of one organism to theoretically be expressed by another organism. Traits and functions of specific DNA and RNA dictate many of the characteristics that different organisms possess, with minor variations occurring in the genetic systems of different domains of life.
However, statement (A), 'DNA was the first genetic material,' cannot be logically inferred from the fact of a universal genetic code. While DNA plays a crucial role in all known forms of life, it is still a matter of scientific debate to determine whether DNA, RNA, or some other form of genetic material first carried genetic information in early life forms, and this cannot be concluded simply from the universality of today's genetic code.

Turbulent flow in humans is a major risk factor for atherosclerosis, the buildup of plaque on arterial endothelium.
Ignoring any potential effects of turbulence, what effect would atherosclerosis have on blood flow?
A) Narrowing of the artery causes the velocity to increase and the hydrostatic pressure to decrease.
B) Narrowing of the artery causes the velocity to increase and the osmotic pressure to decrease.
C) Narrowing of the artery causes the velocity to decrease and the hydrostatic pressure to decrease.
D) Expansion of the artery causes the velocity to decrease and the hydrostatic pressure to increase.
Answers
Answer: (A) Narrowing of the artery causes the velocity to increase and the hydrostatic pressure to decrease.
Explanation:
Atherosclerosis is a disease which allows plaque to build up inside the arteries of a person. Arteries are responsible to carry oxygen-rich blood to heart and other areas of the body.
Plaque consists of cholesterol, calcium, fat, and other substances which are present in the blood. Through time, the plaque hardens the arteries and narrows them. That restricts the oxygen-rich blood flow to your organs and to other parts of your body.
Atherosclerosis can cause serious problems, including stroke and heart attack.
Hence the correct option is (A).

D. Some of the energy went into the ball, and some of it went into the air.
Explanation:
When Jeanie's mallet hit the ball, some of its energy was transferred to the ball, since the ball moved. The loud noise means that some of the energy was changed into sound. Some of the energy stayed in the mallet, because the mallet did not stop moving when it hit the ball. So, some of the energy went into the ball, and some of it went into the air.

Increased levels of which of the following stimulates the thirst mechanism driving increased water intake? Increased levels of which of the following stimulates the thirst mechanism driving increased water intake? aldosterone glucose concentration antidiuretic hormone (ADH) osmolality of extracellular fluid
Answers
Answer:
The renin angiotensin aldosterone system.
Explanation:
We would be speaking from time to time that Aldosterone would be in charge of increasing blood volume by increasing water consumption.
Aldosterone, a steroid hormone from the mineralocorticoid family, produced by the external section of the glomerular zone of the adrenal cortex in the adrenal gland, acts to conserve sodium, both secreting potassium and increasing blood pressure, the blood pressure is through the increase in blood volume, therefore through the increase in water consumption
Increased levels of antidiuretic hormone (ADH) stimulate the thirst mechanism, driving increased water intake.
Explanation:Increased levels of antidiuretic hormone (ADH) stimulate the thirst mechanism, driving increased water intake. ADH is released by the hypothalamus in response to increased osmolality of the extracellular fluid, which indicates dehydration. When ADH levels rise, it signals the kidneys to retain water, and it also stimulates the thirst center in the brain, leading to the sensation of thirst and increased water consumption.

Which did Kepler notice about planetary motion that caused him to propose Kepler’s first law of orbital motion?
Answers
The motions of the planets in the solar system made Keppler propose the laws of planetary motion.
Explanation:
The motions of the planets in the solar system made Keppler propose the laws of planetary motion.In simple words, Kepler's first law can be defined as all planets moved around the sun in the elliptical orbit having the sun as one of the foci.Kepler’s first law means that planets move throughout the Sun in elliptical orbits. An ellipse is a shape that follows a levelled circle.Kepler noticed that the orbits of the planets were ellipses, leading to Kepler's first law of orbital motion.
Explanation:Kepler noticed that the orbits of the planets were not perfect circles, as previously believed, but were actually ellipses. This observation led him to propose Kepler's first law of orbital motion, which states that each planet moves around the Sun in an orbit that is an ellipse, with the Sun at one focus of the ellipse.
Starch has a larger molecule size than glucose so you can conclude that larger molecules are likely than smaller molecules to diffuse across a semipermeable membrane
Answers
Answer:
I can confirm that the answer is less and the answer to the question before that is Only glucose (smaller molecules)
Starch has a larger molecule size than glucose so you can conclude that larger molecules are less likely than smaller molecules to diffuse across a semipermeable membrane. The correct option is A.
What is starch?One of the main sources of dietary energy for people is starch, a type of carbohydrate that is frequently found in nature.
Selectively permeable, a semipermeable membrane permits some molecules to pass through while obstructing others.
The presence of particular transport proteins controls the kind and size of molecules that can flow through a membrane, which determines its permeability.
Therefore, even if starch has a bigger molecular size than glucose, this does not necessarily entail that it will diffuse more slowly through a semipermeable barrier.
The gradient of starch content and the membrane's permeability to starch, both of which can be altered by transport proteins, will determine whether starch can diffuse over a semipermeable membrane.
Thus, the correct option is A.

Humans have a gene, T, that is involved in muscle formation of the tongue. Individuals homozygous for one allele can roll their tongues, while individuals homozygous for the other allele cannot. If both parents can roll their tongues, but their child cannot, what can be said about the mode of inheritance?
Answers
Answer:
Autosomal Recessive mode of inheritance
Explanation:
If both parents can roll their tongue and their child cannot, it means they are both heterozygote for the trait and since this trait skipped a generation, it can be said to be an autosomal recessive mode of inheritance and not an autosomal dominant mode of inheritance as the later does not skip generations.
Final answer:
In simple Mendelian inheritance, if both parents can roll their tongues (a dominant trait) but their child cannot, each parent must be heterozygous. The Hardy-Weinberg formula can be used to calculate the numbers of homozygous dominant, heterozygous, and homozygous recessive individuals in a population based on phenotype frequencies
Explanation:
When both parents have the ability to roll their tongues, but their child cannot, we're looking at a situation involving simple Mendelian inheritance of a dominant trait. Tongue rolling is expressed when an individual is either homozygous dominant (TT) or heterozygous (Tt), and the inability to roll the tongue is a recessive trait (tt). For the child to be unable to roll their tongue, each parent must have been heterozygous (Tt), thereby giving a 25% chance for any of their children to be homozygous recessive (tt) and unable to roll their tongues.
To apply this understanding to a population genetics problem, the Hardy-Weinberg formula can be used. In a small town of 1,500 people, with 500 able to roll their tongues, the formula can determine the frequency of the alleles and subsequently, the expected numbers of homozygous dominant, heterozygous, and homozygous recessive individuals. By knowing the frequency of the dominant phenotype, calculations can reveal the genotype frequencies.

Like other osmoregulatory animals that live in marine environments, sharks maintain tissue concentrations of sodium, potassium, and chloride that are hypoosmotic to the seawater. In contrast to the bony marine fishes, however, sharks do not need to drink seawater. Why
Answers
Answer:
Shark is hyperosmotic relative to sea water.
Explanation:
The sharks that live in the marine environment do not need to drink sea water unlike others.

Answer: Food storage
Explanation:
Stomach is a small pouch like structure which has the ability to store food temporarily.The storage of the food temporarily takes place in the stomach. The food that we eat reaches to the stomach by the help of food pipe.
Here, the food is stored until it is completely broken down into simpler form and enzymes act on them.
The food is then absorbed in the small intestine. But before this food is temporarily stored in the stomach where all the digestive juices and enzymes come to act on the food.
Answer: food storage
Explanation:
The stomach is one of the important parts of the digestive system. It has three main functions to be performed in the animal or human body. It acts as a temporary storage organ for food which passed from the esophagus to the stomach, facilitates the breakdown and mixing of food components with the digestive juices by contraction and relaxation of the stomach muscles and finally aids in digestion of food.
Based on above description, the mechanical and chemical digestion of food by the stomach the other function includes the food storage.
