Answer:
Fish and meat are important sources of protein and fat, though most non-coastal bears rely on carrion (including winter-killed animals)
Explanation:
Some bears, become very effective predators on newborn elk, moose, deer or caribou. Others live in areas where salmon, su.ckers or other fish spawn for part of each year.
When bears emerge from their dens in the spring, food is in short supply. Although bears are hungry, most trees and shrubs won’t leaf for another month and only the grass at lower elevations has begun to green up.

Describe how the carbon cycle transfers matter between organisms and their environment. Include three examples. For each example identify which of Earth's spheres (hydrosphere, geosphere, atmosphere, and biosphere) are involved in the exchange of carbon.
Answer:
Crabon is consumed by plants to produce food and taken by other organism as food from plants. They release then CO2 either through respiration or when they die. During this entire chain, carbon moves through all the spheres of earth
Explanation:
Carbon constitutes the base of life on earth. Carbon and its compound regulate between the different spheres of earth to sustain the ecosystems and flow of nutrients and energy.
Carbon is exchanged between all the hemisphere i.e biosphere, geosphere, hydrosphere and atmosphere. For instance – The ocean consists of largest reserve of carbon on earth (part of hydrosphere), Terrestrial biosphere comprising of non-living organic materials and fresh water sources as sink of carbon in biosphere. The sediments and soils consists of carbon (geosphere) and atmosphere consists of a large amount of gaseous carbon dioxide.
Plants take in gaseous carbon dioxide and produces food that stores in it or is consumed by other living organisms. When these organic animals or plants die eventually, they release the solid carbon contained within them either in the geosphere, biosphere or hydrosphere.
How can heart disease affect a persons health
Answer:
Effects of CHD
Explanation:
With less blood flow, your heart doesn't get the oxygen it needs, and that can cause chest pain, called angina, especially when you exercise or do heavy labor It also can affect how well your heart pumps and make the rest of your body short on oxygen, too.

What does the circulatory system do?
A. Sends hormones to the body
O B. Moves blood around the body
C. Brings oxygen into the body
O D. Defends against invaders
Moves blood around the body
The circulatory system moves blood around the body. Therefore, option (B) is correct.
What is circulatory system?The circulatory system, also known as the cardiovascular system, is responsible for the circulation and transportation of blood, oxygen, and nutrients throughout the body. It includes the heart, blood vessels, and blood. The heart pumps blood to the lungs to become oxygenated, and then circulates the oxygen-rich blood to the rest of the body through arteries.
Veins carry deoxygenated blood back to the heart, where it is pumped to the lungs to receive oxygen. The circulatory system also plays a role in removing waste products from the body, such as carbon dioxide, and helps to regulate body temperature, pH balance, and fluid balance. The circulatory system is essential to maintaining the proper functioning of all cells, tissues, and organs in the body.

Neville has low blood pressure and his pituitary started producing a homorone to maintain water balance his blood pressure eventually returned to normal what best explains what may happen next
Answer: The options are missing in the question,the options are;
A) Positive feedback will stop the release of this hormone.
B) Positive feedback will speed up the release of this hormone.
C) Negative feedback will speed up the release of this hormone.
D) Negative feedback will stop the release of this hormone.
The correct answer to the question is option D
NEGATIVE FEEDBACK WILL STOP THE RELEASE OF THIS HORMONE.
Explanation: The hormone the will be produced is known as Antidiuretic hormone (ADH).it is otherwise known as VASOPRESSIN.It is secreted by the posterior lobe of the pituitary gland.
The main effect of Antidiuretic hormone is to reduce urine output,(diuresis is the production of large amount of urine). Antidiuretic hormone acts in the distal convulated tubules and the collecting ducts of the nephrons of the kidneys,it increases their permeability to water and more of the glomerular filtrate is reabsorbed. Antidiuretic hormone secretion is determined by the osmotic pressure of the blood circulating to the osmoreceptors in the hypothalamus.
As osmotic pressure rises,for example as a result of dehydration, secretion of Antidiuretic hormone increases. With this,there is Increased reabsorption of water reducing the amount of urine produced.This implies that more water is retained in the body making the rise in the osmotic pressure of the blood to be low,for example,after a large fluid intake, secretion of Antidiuretic hormone is reduced,less water is reabsorbed and more urine is produced.
At high concentrations,for example after severe blood loss, antidiuretic hormone causes smooth muscle contraction, especially vasoconstriction in small arteries.this has a pressor effect,raising systemic blood pressure.

Louis pasteur tambien propuso que los microorganismos son la causa de algunas enfermedades escribi que problema pudo haber llevado a pasteur a proponrr esta teoria
Answer:
This is because ladybugs are replaced by pesticides that are responsible for not only contaminating crops but also for releasing dangerous gases into the ozone layer. Therefore, the use of these insects in crops makes the air more pure or avoids contaminating it with life-threatening pesticides for many living organisms.
The microbial theory of disease or germ theory of infectious diseases is a scientific theory that proposes that microorganisms are the cause of a wide range of diseases. These tiny organisms, almost all too small to see with the naked eye, invade humans, animals, and other hosts. Its growth and reproduction within the carrier can cause disease. "Germ" or microbe can refer to a virus, bacteria, protist, fungus, or prion.
Explanation:
The theory was a scientific discovery made in the second half of the 19th century, demonstrated by Louis Pasteur and that replaced previous explanations for the disease, such as the miasmatic theory or the theory of humors. Although highly controversial when proposed, it is now central to modern medicine and clinical microbiology, leading to such important innovations as the development of the vaccine, antibiotic, sterilization, and hygiene as effective methods against the spread of contagious diseases.
a report on the role of chromosomal multiplicity(polyploidy)in the field of agriculture.
Not less than 50 words.
50 points plz help me guys !!
Answer and explanation:
Chromosomal multiplicity, also known as polyploidy, is the name given to the cell or organism that has a numerical change in its whole set of chromosomes (for example, a triploid organism of a diploid species is a polyploid because it has an extra set of chromosomes than the rest of its species). Most species are diploids, but polyploidy is quite common in plants.
In agriculture, polyploidy can be beneficial by giving the plants better chances of survival and/or providing more desirable traits. Crop species such as bread wheat and triticale (a wheat and rye hybrid), for example, have 6 sets of chromosomes. Quinoa, coconut, and peanut are tetraploids (4 sets of chromosomes). Many of these cases of polyploidy in plants of importance for the agriculture field are a result of hybridization (which occurs when two different species are crossed in order to produce offspring with a combination of characteristics of the two-parent species).

What are the weaknesses or inaccuracies in the model the student created?
Answer:
The model appears to show the carbon dioxide molecules entering the blood cell and the oxygen molecules existing the cell.
Answer:
Explanation:
The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.
Si cruzamos dos individuos homocigotos de cobaya, uno negro y otro blanco, y sabemos que el carácter negro es dominante sobre el blanco. Su descendencia tendrá la siguiente características
Answer:
The offspring will be black because they are heterozygous for a dominant trait that is controlled by monogenic inheritance.
Explanation:
Guinea pigs will be heterozygous because they inherit a dominant allele that encodes for the black color and a recessive allele associated with the white color. Heterozygosity is a genetic condition associated with the presence of two alleles at a locus which are inherited from both parents, one from the mother and the other from the father

How do the data that Samantha obtained help explain the way that the body maintains homeostasis during exercise? Include the activities of at least three body systems in your explanation.
Answer:
the way that the body maintains homeostasis during exercise is the removal waste product such as carbon dioxide gas which is produced during cellular respiration.
Explanation:
During exercise, the body needs more oxygen and nutrients. For this purpose, energy is released in the process of cellular respiration. The product of cellular respiration the generation of energy in the form of ATP and carbon dioxide gas. ATP is used by the body while carbon dioxide is removed from the body during breathing. During exercise, the glucose is provided by the digestive system to the mitochondria of the cell and the waste product is removed through respiratory system of the body while the circulatory system sends energy molecules where it is needed in the body and carbon-dioxide to respiratory system for removal.

The Seven Sisters are seven stars located more than 400 light-years away in the Taurus constellation and they can be seen here with Venus and another constellation, Orion. Why do these stars seem so small compared to our Sun, also a star?
A) Our Sun is much larger than any of the Seven Sisters.
B) Our Sun is much closer to Earth than the Seven Sisters.
C) The Seven Sisters are ancient stars; the Sun is a young star.
D) Stars found in constellations are much older and smaller than any other stars.
Answer:
The reason why these stars seem so small compared to our Sun is:
B) Our Sun is much closer to Earth than the Seven Sisters.
Explanation:
The reason behind this is that the sun is at a distance of the earth of 0.000016004 light-years. While the seven stars are at a distance of 400 light-years. Making them so far away that their size is reduced because in physics object size is altered by the perspective of the watcher or observer. Meaning that a ball the size of a car can be seen by our eyes as small as a bean if it is at the proper distance.
