#4-6-Base your answers to questions #4-6 on the information below and on your knowledge of biology. Five individuals had their pulses taken in beats per minute (bpm) before and after exercise. The data are shown in the chart below. 4. State one reason why an individual's pulse rate increased during exercise 5. Calculate the average pulse rate before exercise for this group, to the nearest tenth___________bpm . 6. State why the individuals in this group have different pulse rates before exercise *
Answers
Answer:
4. (answered below); 5. 66.2; 6. (answered below)
Explanation:
4. The individual's heart rate increased because the individual needs more oxygen supplied to their muscles so the heart has to pump the oxygenated blood through the body at a faster rate.
5. Take average of the number of the pulse before exercise:
(68 + 70 + 54 + 64 + 75) / 5 = 66.2
6. Different individuals are different sizes and are in different states of health. An individual who is more physically fit will have a slower rate rate because their heart muscle is "exercised" or worked more and pumps blood more efficiently.

What is a density dependent limiting factor that affects population size?
-Drought
-Climate
-Natural Disasters
-Disease
Answers
Answer:
Disease
Explanation:
In Ecology, certain factors that affect the size of a population can either be dependent on size or not. Density-dependent factors are those factors that affect population of organisms in dependence of how dense the population is. Examples of these density dependent factors are diseases, predation etc.
For example, a certain disease will spread faster among a population of organisms whose size is dense but slower in a scarcely densed population. Hence, disease as a factor is dependent on population size. Note that; Drought, Climate, and Natural Disasters will wipe out a population irrespective of its size.

The function of the hepatic portal circulation is to ________. The function of the hepatic portal circulation is to ________. return glucose to the general circulation when blood sugar is low carry toxins to the kidney for disposal through the urinary tract distribute hormones throughout the body collect absorbed nutrients for metabolic processing in the liver
Answers
Answer:
The correct answer is ''collect absorbed nutrients for metabolic processing in the liver.''
Explanation:
Portal circulation is called that system that is between two large capillary beds, represented by the gastrointestinal organs, pancreas and spleen on the one hand, and the liver on the other. Hence, any venous system of the organism that is located between two capillary territories is called "portal system".The hepatic portal vein collects the deoxygenated blood from the gastrointestinal system, spleen and pancreas, this blood is venous and comes deoxygenated, in addition to being loaded with the nutrients absorbed in the digestive process, so it is a blood subjected to a high overload, but that quickly, thanks to its distribution through the liver, it will be bypassed to various chemical processes to extract a large part of the nutrients from it, and purify and eliminate toxins.
The function of the hepatic portal circulation is to collect absorbed nutrients for metabolic processing in the liver. Therefore, option D is correct.
The hepatic portal system is also known as the hepatic portal circulation or portal venous system. It is a specialized network of blood vessels that carries blood from the gastrointestinal tract, spleen, and pancreas to the liver. It plays a crucial role in directing nutrient-rich blood from the digestive organs to the liver for processing, storage, and detoxification before it is distributed throughout the rest of the body.
The hepatic portal system allows the liver to regulate the composition of blood coming from the digestive organs before it enters general circulation. Thus, option D is correct.

Shortly after his grandfather died his family left Ontario. He was never able to clearly remember the fishing trips. When he was 30 years old he moved back to Ontario with his wife. One weekend they decided to take a trip to northern Ontario to spend the weekend at a resort on one of Ontario’s many lakes. When they got out of the car, they were overwhelmed by the aromatic smell of the trees in the heavily wooded area by the lake. Suddenly, memories of the wonderful weekend fishing trips with his grandfather came flooding back to the him.”

Could this account for other, more traumatic, kinds of “repression” as well?
Answers
Answer:
No.
Explanation:
This is not an example of a repressed memory because these are the good memories whereas the repressed memory are bad memories of childhood. It may be infantile amnesia due to the inability of adults to bring episodic memories memories of situations or events that occurs in their childhood. The sudden re-emergence of this buried memory is the experience of the same situation or place or event that occurs in the childhood. If a person visit to a same place which he gone in their childhood so the person remember the buried memory.

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started. What does this change demonstrate about the evolution of fishes
Answers
Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.
What is atavism?
Recurrence in an organism of a trait or character typical of an ancestral form and usually due to genetic recombination. This leads to the loss of the traits in the evolution.

choose five body systems that are involved in maintaining homeostasis in your body as you answer these assessment questions. Explain how these five body systems work together.
Answers
Answer:
Explanation:
Water Levels
For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water. If the water level gets too low, more concentrated urine is produced so that water is conserved.
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body. Rapid breathing can also help the body eliminate excess heat. Together, these responses to increased body temperature explain why you sweat, pant, and become red in the face when you exercise hard. (Heavy breathing during exercise is also one way the body gets more oxygen to your muscles, and gets rid of the extra carbon dioxide produced by the muscles.)
Conversely, if your body is too cold, blood vessels in the skin contract, and blood flow to the extremities (arms and legs) slows. Muscles contract and relax rapidly, which generates heat to keep you warm. The hair on your skin rises, trapping more air, which is a good insulator, near your skin. These responses to decreased body temperature explain why you shiver, get “goose bumps,” and have cold, pale extremities when you are cold.
Homeostasis of Ions
Body functions such as regulation of the heartbeat, contraction of muscles, activation of enzymes, and cellular communication require tightly regulated calcium levels. Normally, we get a lot of calcium from our diet. The small intestine absorbs calcium from digested food.
The endocrine system is the control center for regulating blood calcium homeostasis. The parathyroid and thyroid glands contain receptors that respond to levels of calcium in the blood. In this feedback system, blood calcium level is the variable, because it changes in response to the environment. Changes in blood calcium level have the following effects:
When blood calcium is low, the parathyroid gland secretes parathyroid hormone. This hormone causes effector organs (the kidneys and bones) to respond to increase calcium levels. The kidneys prevent calcium from being excreted in the urine. Osteoclasts in bones reabsorb bone tissue and release calcium.
When blood calcium levels are high, the thyroid gland releases calcitonin. Calcitonin causes the kidneys to reabsorb less calcium from the filtrate, allowing excess calcium to be removed from the body in urine. Calcitonin also suppresses the formation of active vitamin D in the kidneys; without vitamin D the small intestines don’t absorb as much dietary calcium. Osteoblasts, stimulated by calcitonin, use calcium in the blood to add to bone tissue.

Meiosis is also called as reduction division in this the parent diploid cell divides twice to produce four haploid daughter cells. The daughter cells so produce after cell division contain half the number of chromosomes then that of the parent cells. The germ cells in males and females divide twice or meiotic division occurs in them twice to produce four daughter haploid gamete cells that are sperms (male) and ovum (oocyte) (female). These male and female gametes fuse during sexual reproduction. The sperm fertilizes an ovum to produce zygote.

Select one:
-A:erosion and deposition
-B :condensation and precipitation
-C:rock layer deformation
-D: shifting tectonic plates
Answers
Answer:
I think A
Explanation:
because erosion is the washing away of soil
Erosion and deposition are the formed on this delta. Thus, the correct option is A.
What is Erosion and deposition?Erosion is the action of the surface processes such as water flow or wind which removes the soil, rock, or dissolved materials from one location on the Earth's crust and then transports it to another location on the Earth's crust where it is deposited. The erosion is distinct from that of weathering that involves no movement.
Deposition is the laying down of the sediment carried out through the wind, flowing water, the sea or ice. Sediment on the Earth's crust can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by the organic activity such as sea shells or by evaporation.
Therefore, the correct option is A.

Which elements are likely to have similar properties to calcium because they have the same number of valence electrons as calcium
Answers
Answer:
The correct answer would be - strontium, magnesium, beryllium.
Explanation:
As we know that the number of the same valence electrons is most likely to exhibit similar physical and chemical properties so the elements of the particular group in the periodic table have a similar number of physical and chemical properties and a similar number of the valence electrons.
For example, group 2 elements are known as alkaline earth metals, and strontium, magnesium, beryllium, and calcium are the same group elements thus, they have the same chemical and physical properties as they have 2 valence electrons.
