The nervous system makes you thirsty. The integumentary system makes you sweat.
The hypothalamus is part of the nervous system and controls vegetative functions, such as hunger, thirst and body temperature. When you run a race, your body starts to lose fluids due to sweat. At that moment the nervous system (through the hypothalamus) trying to maintain homeostasis in your body signals that you are thirsty.
As already mentioned above, when you participate in a race you start to sweat. This is a reaction of the integumentary system, through the skin, releasing fluids to regulate your body temperature.

Which of the following statements about muscles and the muscular
system is true?
O The three types of muscle tissue are skeletal muscle, smooth muscle, and involuntary
muscle.
O Muscles always work independently to move parts of the body.
All muscle action is voluntary, or able to be consciously controlled.
OSmooth muscle moves food through the digestive system.
Smooth muscle moves food to the digestive system, which is the true statement about the muscle and muscular systems. Hence, the fourth option is the correct answer.
What are different types of muscles?In the human body, there are three types of muscles: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle is called voluntary muscle.
Voluntary muscles move in response to commands. Examples are the muscles of the hand and legs. They move when an organism wants to move. Cardiac muscle and smooth muscle are involuntary in nature.
The contraction and relaxation of involuntary muscles don't depend on the individual's wish. Smooth muscles are present in the internal organs such as the intestine, stomach, etc. When food reaches the stomach, the stomach muscle contracts and relaxes to digest the food. The cardiac muscle is present in the heart. It always works.
Hence, option 4 is the correct answer, as smooth muscle moves food through the digestive system.

If Tom Harris had type AB blood and Mary had type O, could the type O child they brought home be their child? * No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B. Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominate to O. Yes; the baby inherited type O blood from the mother Mary Harris which is dominant to the genes for both A and B.
Explanation:
No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B.
The study of blood is called hematology. The component of blood is RBC, WBC, platelets, and plasma.
The correct answer to the question is option B.
What is a blood group?A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.The genes A and B are dominant over O therefore the O blood group can not be seen in offspring.
Hence, the correct answer to the question is option B is Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominant to O.

On Isle Royale, wolves are the main predators of moose. The graph shows the changing wolf and moose populations on the island over a 50-year time span.
The graph plots the populations of moose and wolves in separate lines from 1955 to 2005. The two populations appear to follow opposite trends: when one population is higher, the other population is lower.
Which statement provides the strongest explanation for the trends in the two populations?
A. The populations of predators and prey are limited by abiotic factors only.
B. Predation acts a density-dependent limiting factor on prey, but not on predators.
C. Predation acts as a density-independent limiting factor on predators, but not on prey.
D. Predator-prey relationships act as density-dependent limiting factors on both predators and prey.
Answer:
D
Explanation:
The statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.
What is predator?Predator is defined as an organism that mostly hunts and consumes other organisms for food. The term "predator" refers to a species that hunts and eats specific other organisms. The animals that predators consume are referred to as prey.
Predator-prey interactions and prey-predator interactions are both crucial density-dependent population controls. The other population's size determines how each population changes in size. When the population density reaches a particular point, a density-dependent limiting factor takes effect. Competition, parasitism, and disease are other instances of density-dependent limiting variables.
Thus, the statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.

Explain the relationship between the number of whales, the number of plankton (Biomass), and the amount of CO2 (Carbon Dioxide) in the atmosphere.
Answer:
Plankton are producers therefore they use the CO2 in the atmosphere and convert it to oxygen. Whales eat the plankton while sometimes using the oxygen that the plankton produces. In this situation, the whale is a primary consumer, or a heterotroph, as the plankton is the producer, or autotroph. Hope this helped :D

Mass can neither be created nor destroyed.
Mass can only be destroyed by physical transformations.
Answer:
3 Mass can neither be created nor destroyed.
Explanation:
Not number 1 because The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. Not 2 One of these is called the law of conservation of mass , which states that during a chemical reaction, the total mass of the products must be equal to the total mass of the reactants. not 4 go back to number 1 and look why so its 3

So meiosis produces egg or sperm
Answer:
Your answer is correct, it is eggs
Explanation:
In meiosis in females is called oogenesis while in males it is called spermatogenesis so it does produce a little bit of both because it needs to produce the chromosomes for the offspring half male and half female. It also produces 4 gamete cells and around that time can form the offspring which then can form whatever reproductive organ either it's going to be a girl or a boy. But in meiosis, it mostly produces the eggs because the sperm fertilizes the egg hence the whole Meiosis I and II processes.

Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E. e. eschscholtzii?
Answer:
E.e. oregonesis
E.e. platensis
E.e. xanthoptica
E.e. croceater
E.e. eschscholtzii
E.e. klaubori
Explanation:
The species mentioned above are probably separate species from E.e. eschscholtzii, which arose through ring speciation that occurs when a species is geographically distributed in a circular pattern. After this distribution, geographic isolation occurs, causing individuals in each different region to evolve differently, becoming other species, even reaching the point where it is not possible to cross them.

Dr. Robert Hazen has worked to develop a hypothesis that explains
the origin of life on Earth. His work has focused on hydrothermal vents, which are cracks in the ocean floor. Water heated by molten rock beneath the crust escapes from these vents at very high temperatures, producing hot, high-pressure environments at the vents on the ocean floor.
In order to provide evidence that these vents may be areas where life originated, which of the following states a null hypothesis Hazen might have used to begin his research?
(A) Organic molecules were transported to the hydrothermal vents via a meteorite, thereby seeding them with precursors for more complex molecules.
(B) The temperatures and pressures found in hydrothermal vents resemble conditions described in currently accepted origins of life hypotheses.
(C) Organic waste sinking to the ocean floor would have used the unique hot water environment as an energy source to begin manufacturing food.
(D) Chemosynthetic organisms can best develop in the hydrothermal environment, manufacturing nutrients for other living things to feed on.
Answer:
(B) The temperatures and pressures found in hydrothermal vents resemble conditions described in currently accepted origins of life hypotheses
Explanation:
We are told that Dr. Hazen wants to develop a hypothesis that explains
the origin of life on Earth.
Now, he focused on hydrothermal vents. That Water heated by molten rock beneath the crust escapes from these vents at very high temperatures, producing hot, high-pressure environments at the vents on the ocean floor.
This means the null hypothesis will be temperatures and pressures found in this initial condition he described while any other different from it will be the alternative hypothesis.
Looking at all the given options and comparing with the initial hypothesis conditions in the question, the correct answer is option B.
The origin of life can be seen as the natural process in which the origin of living things happen through non-living matter or smaller organic compound.
The null hypothesis is:
(B) The temperatures and pressures found in hydrothermal vents matches the conditions described in currently accepted origins of life hypotheses.
The null hypothesis for Dr. Robert Hazen hypothesisThe hypothesis says that hydrothermal vents are cracks in the ocean floor.It also states that there were high temperatures and high pressure environment.Thus, the option (B) The temperatures and pressures found in hydrothermal vents matches the conditions described in currently accepted origins of life hypotheses is the best null hypothesis for Dr. hazen to begin his research.
