Via the mother's cardiovascular system and the ________ , the respiratory system supplies oxygen to and removes carbon dioxide from the blood of a developing fetus.
Answer:
The mother's cardiovascular system and the placenta.
Explanation:
Babies receive their oxygen and get rid of the carbon dioxide with the help of both the cardiovascular system of the mother and the placenta. The gases dissolve through the placenta and then gets exchanged in the cardiovascular system of the mother. So the answer is the mother's cardiovascular system and the placenta.

what is DNA explain the concept of DNA and RNA
Answer:
DNA is the abbreviation of deoxyribonucleic acid, while RNA stands for ribonucleic acid. Both the RNA and DNA carry certain genetic information, however, there is some difference between the two. DNA comprises sugar deoxyribose and RNA comprises sugar ribose. DNA is found to be stable under alkaline conditions, while RNA is not stable.
DNA is a molecule having double strands, while RNA is a single-stranded molecule. There is a slight difference in the base-pairing found in the two nucleic acids. In DNA, the bases present are adenine, thymine, cytosine, and guanine. While RNA utilizes adenine, uracil, cytosine, and guanine bases. Both RNA and DNA perform distinct roles in humans. RNA codes for amino acids and functions as a messenger between the ribosomes and the DNA to produce proteins. While DNA is accountable for storing and conducting genetic information.
All of the following would be visible on a karyotype except
aneuploidy.
polysomy.
trisomy.
homologous chromosomes.
Answer: I think aneuploidy id wait for someone else to confirm this
Explanation:
All of the following would be visible on a karyotype except is aneuploidy
How to identify karyotype?The normal karyotype of the species is described as 46, may XX or XY, in which the first number of chromosomes is followed by a comma indicating the chromosomes. Thus, 46, XX corresponds to the karyotype of a woman; and 46, XY represents a male karyotype.
Aneuploidy is the presence of an abnormal number of chromosomes in a cell so this is the exception.

Answer:
the answer is b
Explanation:
Please explain study of variation patterns in different taxon.
Answer:
By using genetical and ecological approaches
Explanation:
Genetic variation is useful to study the diversity of the species and to understand both intraspecific and interspecific variation patterns. In genetics assays, two or more genetic sequences belonging to different organisms are compared in order to determine nucleotide differences (i.e., homology level) between the complete sequences, which enable to determine the evolutionary relationships between taxa.
Ecological diversity is associated with the variation of terrestrial and aquatic ecosystems. Ecological variation across species can be represented by different measures such as niche variation among individuals, the number of trophic levels, etc. Ecological variation patterns may affect the ecological dynamics of species and their communities, thereby being of vital importance for diversity classification studies.

Explain the mechanism responsible for summation of contractions and the increase in height of contraction when the stimulus frequency is increased.
Answer:
The higher the stimulation frequency, the contractions will be more continuous and even additive.
Continuous stimuli reactivate muscle contraction once the action potential cycle is complete.
Explanation:
Muscle contractions can be continuous or cumulative once the action potential curve drops, since the action potential at the top of the mountain is in a refractory period.
I knit a graph of what cumulative contractions are like due to continuous stimulation.
In the graph I leave you pointed out some references:
mr = refractory moment
mnr = non-refractory moment (where the new stimulation is accepted and a more powerful cumulative muscle contraction is generated)
PA = potential for muscle action or contraction itself.

The series that correctly lists the eight taxonomic levels in order, from the broadest group to the most specific group is: domain, kingdom, phylum, class, order, family, genus, species.
What is taxonomic order?Taxonomic order refers to the systematic arrangement of organisms into a hierarchy of groups based on their shared characteristics and evolutionary relationships. Taxonomy is the science of identifying, describing, and naming species, and it helps to organize the diversity of life on earth into groups that reflect their evolutionary history.
The taxonomic order starts with the broadest category, the domain, and narrows down to the most specific category, the species. Each category represents a level of classification that shares certain characteristics, and the categories are nested within each other, forming a hierarchical structure.
The eight main taxonomic levels in order, from broadest to most specific, are domain, kingdom, phylum, class, order, family, genus, and species. This hierarchical system of classification helps scientists to better understand the relationships and diversity of organisms in the natural world.

Consider a pendulum swinging. Which type(s) of energy is/are associated with the pendulum in the
following instances:_________.
1. the moment at which it completes one cycle, just before it begins to fall back towards the other end
2. the moment that it is in the middle between the two ends
3. just before it reaches the end of one cycle (before step 1
a.
1. potential and kinetic
2. potential and kinetic
3. kinetic
b.
1. potential
2. potential and kinetic
3. potential and kinetic
c.
1. potential
2. kinetic
3. potential and kinetic
d.
1. potential and kinetic
2. kinetic
3. kinetic
Answer:
1 - Potential 2 - Kinetic 3 - Potential and Kinetic
Explanation:
Potential energy is the energy that an object has when it has a certain amount of elevation from the ground level and to calculate it, we can multiply the mass of the object with the gravitational acceleration constant.
hKinetic energy is the energy that the object has when it has a speed above zero, when it is moving. We can calculate the kinetic energy by multiplying the mass of the object with it's speed.
In the first option, the pendulum has a height because it is just about to fall down, but it has no speed. So it only has potential energy.
In the second option, the pendulum is between the two ends so it is at the equilibrium point where it has no elevation but it has speed. So İt only has kinetic energy.
In the third option, the pendulum is still moving to the maximum height, so it has both elevation and speed, giving it both kinetic and potential energy.

Answer:
except option 2 all of them are applied
Explanation:
TS is 67 years old with a long history of knee osteoarthritis for which he self-medicates regularly with over-the-counter (OTC) naproxen. He is in the clinic today complaining of a swallowing difficulty that has progressively worsened over the past several months. He has otherwise been healthy and has not seen a doctor in many years. TS denies significant past medical history. A review of systems is negative except for arthritic symptoms and swallowing difficulty. He denies noticing blood in his stool and vomiting blood. He denies history of gastroesophageal reflux disease (GERD) and ulcer. He does not drink alcohol, although he drank heavily many years ago. He does not smoke. TS describes the dysphagia this way: "Food gets stuck in my throat, and I can’t get it down." The feeling occurs only after he has ingested solid food; liquids are not a problem. There is burning chest pain associated with meals. He is scheduled for an upper GI endoscopy.
Required:
a. What is the likely cause of the dysphagia?
b. What advice should he be given regarding his OTC medication at this time?
c. What are the usual signs and symptoms of GERD? How will it be managed?
Answer:
Dyspahgia and alcohol are related.Past years of alcohol(besides medication for asthma,sedatives,antidepressants) intake may trigger the transformation of some of the cells lining the oesophagus. The oesophagus is lined with stratified epithelial cells. Persistent alcohol intake may lead to transformation these cells to abnormal cell of columnar epithelial.They are known as Dysplasia
The dysplasia in the patients leads to Barrett's esophagus.These Columnar cells makes the oesophagus of TS prone to esophageal adenocarcinoma .The dysplasia may lead to tumour,and therefore obstruction of the oesophagus.This may therefore account for the Dysphagia experienced by TS,Hence peristalsis is inhibited and soild foods can not be moved down,
2.The state of the medication should be liquid. Because of the difficulty in swallowing,which will not allow the medication to reach stomach,for absorption.Intravenous administration can also be adopted.
3. Dysphagia,burning sensation due to acid reflex , pain in the chest and upper abdominal part ,tendencies to regurgitate foods,bad breath, are some of the symptoms of Gastroestro esophageal reflux,
Abstinence from alcohol,oily foods,smoking,avoiding lying down immediately after eating,avoidance of carbonated drinks,tight clothing at the waist, and use of herbal products e.g marshmallow are examples of method of managements
Use of anti acids,H2 blockers,and application of erythromycin,together with surgery are used for the managements.

__ ions leave the cytoplasm rapidly during the repolarization phase. both A and C none of the above Calcium Sodium Potassium
Answer:
Potassium ions
Explanation:
During repolarization, more potassium ions leaves the cell making the cell less positive and more negative bringing about repolarization.
The event of repolarization comes after the depolarization of the cell wherein more sodium ions which are positively charged flows into the cell letting the cell become less negative leading to depolarization of the cell.
