The following questions are answered below.
Explanation:
1. The following statement is not true for the reproductive system is it includes both internal and external reproductive structures.
2. Fertilization of ovum most often occurs in the oviduct or fallopian tube.
3. The primary hormone is responsible for development and maintenance of female sex characteristics is estrogens.
4. The layer of the uterus from which tissue is sloughed during mensuration is the endometrium.
5. The cremaster muscle raises and lowers the testes to maintain proper temperature for sperm production.
6. The period of pregnancy during which the basics of all major organ systems appear is the first trimester.
7. The last major organ(s) to mature during fetal development is/are the brain.
8. After undergoing meiosis, an egg and sperm each contain 23 chromosomes, while a developing fetus contains 46.
Final answer:
The reproductive system is responsible for the production and transport of gametes, but it does not produce hormones like GH and ADH. Fertilization typically occurs in the fallopian tube, estrogen is key for female characteristics, the cremaster muscle regulates testes temperature, the fetus grows rapidly in the third trimester, organ systems appear in the first trimester, the lungs mature last, and post-meiosis, gametes carry 23 chromosomes each, combining to form a zygote with 46.
Explanation:
The reproductive system performs critical functions for the perpetuation of species, including humans. Let's examine the questions about it sequentially:
The incorrect statement about reproductive system is "It produces GH and ADH." These hormones are actually secreted by the pituitary gland and are not directly related to reproductive processes.Fertilization of an ovum most often occurs in the "oviduct or fallopian tube."The primary hormone responsible for development and maintenance of female sex characteristics is "estrogen."The layer of the uterus from which tissue is sloughed during menstruation is the "endometrium."The cremaster muscle raises and lowers the testes "to maintain proper temperature for sperm production."The period of pregnancy during which the developing fetus rapidly increases in size is the "third trimester."The period of pregnancy during which the basics of all major organ systems appear is the "first trimester."The last major organ(s) to mature during fetal development is/are the "lungs."After undergoing meiosis, an egg and sperm each contain "23 chromosomes," while a developing fetus contains "46."A 76-year-old woman with emphysema presents with respiratory distress that has worsened progressively over the past 2 days. She is breathing through pursed lips and has a prolonged expiratory phase and an oxygen saturation of 76%. She is on home oxygen at 2 L/min. Your initial action should be to:A. increase her oxygen flow rate to 6 L/min.B. administer a beta-2 agonist via nebulizer.C. place her in a position that facilitates breathing.D. auscultate her lungs for adventitious breath sounds.
Answer: The correct answer to the question is option C
PLACE HER IN A POSITION THAT FACILITATES BREATHING.
Explanation: Emphysema is a condition of the respiratory system,in emphysema,there is significant damage of the air sacs in the lungs altering breathing and exchange of gases and leading to breathlessness.
Respiratory distress,pursed lips breathing,prolonged expiratory phase and low oxygen saturation all indicates chronic obstructive pulmonary disease.
One of the initial management of respiratory distress is proper positioning.cardiac positioning is the best position to ease breathing difficulty.
The woman should be made to lie on her back with a pillow under her head to support her,the best should be raised at an angle of 30° ,and two pillows should be placed under the hands and arms to support it two pillows placed under the both ones for support too.
This type of position will help relief tensing in the patients abdominal and respiratory muscles and as well ease the tension that occurs to the chest during gravity,promote venous return and prevent thromboembolism.
The patient can also be made to lie on her back,her head elevated with pillow and a pillow will be placed between her legs.
These positions makes the respiratory airways to relax and thus easing breathing.
Based on the general trend of your data, what happened to the heart rate and pulse amplitude immediately after exercise and then during recovery from exercise? What is the physiological advantage of these changes?
Exercise is very vital to the body,it a form of physical activity.the sole aim of excercise is to maintain stamina, flexibility,keep fit and be overly healthy and well.
When we excercise, our heart rate increases and then it returns to the normal rate when with rest,when we take a break.there is reflection of vasoconstriction in the fingers as the blood is shunted to only the exercising muscles because it is noted that the pulse amplitude of the heart is always small after excercise and and increases slowly during recovery.
The amount of blood the heart pumps in a minute,that is the amount of blood ejected by the contraction of the left ventricle into systemic circulation increases when we are exercising and resistance to blood flow by skeletal muscles decreases.the blood vessels will try to adapt to the condition (exercise) inorder to control blood flow and as well meet energy demands.
When we finish exercising,our body temperature increases which will inturn cause increase in the pulse rate and the blood in our body makes way to our skin,hands and legs inorder to clear off the energy that was generated by the body(muscles) during exercise

do viruses have the ability to adapt
no i don't think they can
Answer:
. A virus can live in two different phases – the lytic phase (where the virus actively replicates in a host cell) and the lysogenic phase (where the viral DNA incorporate itself into the cell’s DNA and multiples whenever the cell multiplies). Sometimes a host does not have enough energy or supplies to support the virus to actively replicate, so it will switch to the lysogenic phase. The virus can eventually reenter the lytic phase when conditions are right.

Select the one statement that is false: a) All species of Plasmodium can cause relapses. b) Merozoites are the form of Plasmodium that invades red blood cells.c) Plasmodium sexual reproduction involves fusion of a male and female cell to produce a zygote.d) The "knobs" on infected red blood cells increase P. falciparum mortality by reducing immune system clearance of Plasmodium-infected red blood cells. e) Plasmodium has an organelle that specializes in taking up and using hemoglobin as a nutrient .f) Nearly all malaria deaths are caused by P. falciparum.
ANSWER: (A) All species of Plasmodium can cause relapses.
EXPLANATION: All species of Plasmodium can cause relapses is FALSE.
Based on series of research on malarial parasites, only two species of Plasmodium can cause relapses (P. vivax and P. ovale.).
These species of plasmodium are known for causing relapses i.e the reappearance of parasitemia after treatment of affected individuals.
However, it is assumed that the subset of the parasites that caused the primary infection caused the relapses.
Furthermore, individuals who are cured of their blood stage may have a subsequent infection without reinfection (relapses). This is caused by the presence of the latent (exo-erythrocytic) stage, which exhibit dormancy in the body.
Answer:
Select the one statement that is false: a) All species of Plasmodium can cause relapses
Explanation:
This statement "All species of plasmodium can cause relapses" is false, because only two species of Plasmodium can cause relapses. These two are Plasmodium vivax and Plasmodium ovale. These species can cause malaria, people can develop symptoms even years after the initial infection due to activation of a dormant hypnozoite in the liver.

A client has been diagnosed with right-sided heart failure based on symptomology. The cardiologist will confirm this suspicion through diagnostics. Which diagnostics are used to reveal right ventricular enlargement?A. electrocardiogramB. chest radiographC. echocardiography
Answer:
A. electrocardiogram and C. echocardiography.
Explanation:
The two diagnostics used to confirm if a person has ventricular enlargement are electrocardiogram and echocardiography. Electrocardiograms mostly detect the electrical activity of the left ventricle, and if there is a problem on the right ventricle, it might be hard to confirm it with this procedure, so the best option is to complement it with echocardiography since it gives an image of the right ventricle walls.
Answer: The correct answer to the question is option A
ELECTROCARDIOGRAM
Explanation: Right sided heart failure is otherwise known as pulmonary heart disease or cor pulmonale.
In a healthy heart,deoxygenated blood enters the right atrium through the superior and inferior vena cava,the right atrium contracts opening the tricuspid valve and making way for the blood to empty into the right ventricle.the right ventricle further contracts and the pulmonary valve opens,the deoxygenated blood from the right ventricle goes into the pulmonary trunk and into the right and left pulmonary artery,the right and left pulmonary artery empties the deoxygenated blood into the right and left lungs for gaseous exchange.(oxygenation)
When the right side of the heart is diseased,there will be a failure in carrying out the above stated functions.
Right sided heart failure is simply defined as the inability of the right side of the heart to take-up or pump deoxygenated blood into the lungs for oxygenation.
The sign and symptoms if right sided heart failure are mainly lethergy, dyspnea, fatigue and oedema.
Electrocardiogram is one of the diagnostic procedure for right sided heart failure,it will reveal an impairment in the heart rate and rythym and also an impairment in pulmonary artery pressure.
Explain how it is that actin and myosin in the sarcomere never actually shorten and yet the muscle as a whole does.
Answer:
The muscle fibers are pulled by the myosin and sarcomere together, resulting in the shortening of the fibres, but the sarcomere and myosin just move.
Explanation:
During muscle contraction, each sarcomere shortens, bringing the Z discs close together. There is no change in the width of the A band but both I bands and the H zone almost completely disappear. These changes are explained by actin and myosin filaments sliding past one another, so that the actin filaments move into A band and H zone. Muscle contraction thus results from an interaction between the actin and the mosin filaments that generates their movement relative to one another. The molecular basis for this interaction is the binding of the myosin to actin filaments that generate their movement relative to one another.
During muscle contraction, the actin and myosin filaments in a sarcomere do not actually shorten. Instead, they slide past each other, pulling the actin filaments towards the center and reducing the overall length of the sarcomere. This leads to the muscle's overall contraction, even though the individual filaments themselves do not shorten.
Explanation:The actin and myosin filaments in the sarcomere do not actually shorten during muscle contraction. Instead, they slide past each other in a process known as the sliding filament model of contraction. The myosin heads form cross-bridges by attaching to the actin filaments, pulling them towards the center of the sarcomere. This action reduces the distance between consecutive Z discs, thus shortening the sarcomere. The energy for this process is provided by ATP. While some regions such as the H zone and I band within the sarcomere do shorten, the thick (myosin) and thin (actin) filaments remain the same length. Their overlapping movements lead to the overall contraction of the muscle.

Divisions of the cerebral hemispheres that are named after the overlying skull bones are
Answer:
Divisions of the cerebral hemispheres that are named after the overlying skull bones are called Lobes
Explanation:
By means of a prominent groove, called the longitudinal fissure, the brain is divided into two halves called hemispheres. At the base of this fissure lies a thick bundle of nerve fibers, called the corpus callosum, which provides a communication link between the hemispheres. The left hemisphere controls the right half of the body, and vice-versa, because of a crossing of the nerve fibers in the medulla.
The central sulcus and the lateral sulcus, divide each cerebral hemisphere into four sections, called lobes.The central sulcus, also called fissure of Rolando, also separates the cortical motor area (which is anterior to the fissure).
The cerebral cortex is classified into four lobes, according to the name of the corresponding cranial bone that approximately overlies each part. Each lobe contains various cortical association areas – where information from different modalities are collated for processing. Together, these areas function to give us a meaningful perceptual interpretation and experience of our surrounding environment.
Answer:
Brain lobes
Explanation:
The brain has two hemispheres (left and right) that are formed each by 4 lobes: parietal, and occipital, frontal and temporal. These lobes are named depending on the overlying skull bones

What may happen if a species goes extinct?
Answer:
Every living thing plays a role in the food chain and Earth's ecosystems, and the extinction of certain species, whether predators or prey, can leave behind significant impacts. ... “When a predator goes extinct, all of its prey are released from that predation pressure, and they may have big impacts on ecosystems.”
Explanation:
Extinctions can have serious ramifications on ecosystems and human welfare, such as collapsing ecosystems, affecting food production, and compromising air and water quality. The loss of keystone species is especially critical as it can lead to extinction cascades.
When a species goes extinct, it can have significant implications for human welfare and the health of ecosystems. Although extinction is a natural part of macroevolution, the current accelerated extinction rate could result in the loss of tens of thousands of species within our lifetimes. This loss can lead to the collapse of ecosystems, which negatively impacts food production, clean air and water, and human health. Especially troubling is the loss of keystone species, which can trigger an extinction cascade and disrupt entire communities. Therefore, the practical importance of biodiversity loss is significant, affecting ecological balance and the benefits that humans derive from nature.
What are intertidal communities so stressful on their inhabitants
Explanation:
Intertidal communities are found within the shoreline area reached by waters of the highest high tide and uncovered at the lowest low tide
Stressful environment due to interaction of physical factors, e.g., wind, waves, sunlight Organisms must be able to withstand desiccation, searing heat and freezingOrganisms on rocky shores are faced with challenges not encountered by organisms in the deeper ocean alternately submerged by incoming tide and exposed to air by ebbing tide exposed to salinity fluctuations due to rain and evaporation pounded by high energy wavesOrganisms attached to high intertidal locations face greatest challenge to maintain suitable body temperature and avoid water loss and their adaptations include: large body exposes less surface area, light color reduces heat gain , special adaptations of kidneys , aggregate in large clumps , close shells at low tide, e.g., barnacles Organisms in high latitudes produce anti-freezing type compounds during winter, these compounds are proteins located in their bloodLoss of biodiversity matters not only with regard to mammals or other vertebrates, but also microbes. What statement below would encourage a wide range of people to view microbes as worthy of discovery and protection from extinction?
A. Microbes may be the most sensitive to the next large extinction event.
B. Microbes may produce unique proteins useful in genetic research.
C. Microbes play a role in digestion.
D. Microbes are much greater in species number than any other taxa on Earth.
Answer:
B. Microbes may produce unique proteins useful in genetic research
Explanation:
Biodiversity refers to the diversity of living beings present on Earth. The biodiversity is a very important component of the ecosystem as these living organisms are interlinked with each other. Therefore, the loss of biodiversity will affect the ecosystem.
When we look at the biodiversity a layman considers the living organisms which can be seen with eyes but the diversity also exists at the level of the micro-organisms.
The man-made activities are not only harming the macroscopic but also microscopic organisms. The microbes play an important role in our life like these days they are used by the scientific community to study the genetic and related fields like molecular biology. The microbes produce proteins that are consumed by humans.

If you pick up a novel object that you've never seen before and run your fingers along it to get a better sense of its shape, you are engaging in A. increased touch sensitivity. B. two-point touch. C. proprioceptive feedback.D. nociception. E. a haptic exploratory procedure.
When you run your fingers along an object to sense its shape, you are engaging in a haptic exploratory procedure. This active touch involves haptic perception, which integrates various sensory inputs and feedback mechanisms to help recognize the object's properties.
If you pick up a novel object that you've never seen before and run your fingers along it to get a better sense of its shape, you are engaging in E. a haptic exploratory procedure. Haptic perception is involved when we recognize an object by touching it. This perception is a combination of the senses in the skin, the position of the hand, and how the fingers conform to the object.
By actively moving your fingers over the object, you're using active touch, which tends to be more informative for determining an object's shape and other properties. Through touch, we can discern various characteristics such as size, weight, texture, stiffness, and so forth. This information is processed by receptors in our skin and then combined in our central nervous system to form a detailed understanding of the object.
Two-point discrimination, proprioceptive feedback, and nociception are all different aspects of the haptic system that serve their unique purposes in tactile sensation.
Overall, when you explore an object with your hands to learn about its shape and other qualities, you are primarily using haptic perception.
