Answer:
Inside vessels
Explanation:
humans have a closed circulatory system in which blood flows from heart to body in vessels
Blood moves through the circulatory system through the systemic circulation and pulmonary circulation.
In the systemic circulation, oxygenated blood present in the left ventricle is pumped into the aorta and passes into the systemic arteries that carry blood throughout the body through the smaller arterioles and then ultimately systemic capillaries, where oxygen is given to the tissues and carbon dioxide is picked.
The deoxygenated blood then moves from capillaries to the systemic venules which merge to larger veins and lastly moves to the right atrium.
In pulmonary circulation, deoxygenated blood is pumped from the right ventricle to the pulmonary trunk which is branched into pulmonary arteries that carry it to the right and left lungs for oxygenation. After loading oxygen, it is carried to the left ventricle.

The diffrence of a number and 4 thirds 11 thirds. What is the number?
Answers
For the word problem, If the difference of a number and the fraction \(\frac{4}{3}\) is \(\frac{11}{3}\), then the number is 5.
How do we solve for the number?The above mathematical problem is a word problem. Word problems are problems that are written in words, rather than in symbols.
To solve for the difference or mystery number, we say, Let x be the number.
The problem states that x - \(\frac{4}{3}\) = \(\frac{11}{3}\),
movin - \(\frac{4}{3}\) to the other side of the equation,
we get x = \(\frac{11}{3}\) + \(\frac{4}{3}\) = \(\frac{15}{3}\)
We solve the fraction by dividing 15 by 3
\(\frac{15}{3}\) = 5

Below is a DNA template strand that serves as a gene used to create a specific protein. The DNA template is read from LEFT to RIGHT. Please determine the sequence of amino acids for the protein that is produced using this sequence of DNA.
AAATAAGTCGGTCACCTAGTC
Answers
To determine the sequence of amino acids for the protein produced using the given DNA template strand, we need to first transcribe the DNA into messenger RNA (mRNA), and then translate the mRNA into the sequence of amino acids using the genetic code.
Transcription involves copying the DNA template into a complementary sequence of mRNA, where thymine (T) is replaced by uracil (U). So, the mRNA sequence for the given DNA template strand would be:
UUAUUAGACCGAGUGGAUCAG
Using the genetic code, we can then translate the mRNA sequence into the sequence of amino acids that make up the protein. Each codon (a sequence of three nucleotides) in the mRNA sequence codes for a specific amino acid, as specified by the genetic code. The sequence of amino acids corresponding to the mRNA sequence would be:
Phenylalanine - Asparagine - Aspartic acid - Arginine - Valine - Serine
So, the sequence of amino acids for the protein that is produced using the given DNA template strand would be:
Phenylalanine - Asparagine - Aspartic acid - Arginine - Valine - Serine.

A scientist isolates a microbe from a contaminated water source. She thinks that the organism might be a new bacteria that is capable of surviving in the presence of lead, a heavy metal. She makes tubes of growth medium containing either no lead, 0.1 mg lead, 0.25 mg lead, 0.5 mg of lead or 1 mg of lead. She inoculates each tube with the 10 x 103 cells of the new organism and then incubates the inoculated medium at 37oC. After 48 hours, she examines the tubes of medium and finds that there is no growth in any of them. However, she finds that the bacteria grew fine in medium that did not contain any lead. She decides to repeat the experiment using lower concentrations of lead than those she used initially.
what conclusion can the scientist in this scenario make from her result?
1) all contaminated water contains high levels of lead and other heavy metals
2) the amount of lead used in the experiment killed the bacteria being tested
3) all experiment should be repeated three times or more
4) lead-contaminated water does not contain any bacteria at all
5) the test bacteria take more than 48 hours to grow in the laboratory when incubated at 37 degree Celsius
Answers
Answer:

Explanation:
The positive control is the treatment where bacteria grew without lead. Since positive control indicates the presence of bacteria in the experimental conditions, it is possible to confirm that they only death in presence of this metal. However, it is important to note that it is imperative to repeat this experiment three times and also to include a negative control in order to confirm these results.

From these observations you conclude: A. The primary structure of the protein contains multiple cysteine residues that are hydrolyzed by the chemical reductant. B. The protein is most likely composed of multiple polypeptide chains that are held together by disulfide bonds C. The protein is most likely composed of a helices that are held together by disulfide bonds. D. The primary and secondary structure of the protein depends on disulfide bonds. E.

Answers
Answer:The protein is most likely composed of multiple polypeptide chains that are held together by disulfide bonds
Explanation:
The Disulfide bonds in protein membranes are usually seen in bacteria and eukaryotes.
Answer:
Option B
Explanation:
Since the usual shape of the protein is supposed to be globular and even after treatment, it still produces the same globular proteins despite the reduction of its disulphide bonds.
The disulphide bonds should have disrupted the shape formation if it had been a mechanism for its shape formation but since multiple globular polypeptide resulted from the treatment it can be assumed that the multiple polypeptide chains are held together by disulfide bonds which are hydrolyzed by the chemical.

Precession of Earth's axis causes
A axial tilt
B a change in the North Pole star
C seasons
D day and night
Answers
Precession of Earth's axis causes a axial tilt.
The angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane, or, more precisely, the angle between its equatorial plane and orbital plane, is known as axial tilt, sometimes known as obliquity.
Unlike orbital inclination, it is different. The two axes point in the same direction with an obliquity of 0, meaning the rotational axis is parallel to the orbital plane.
The Earth's rotational axis, for instance, is the hypothetical line that traverses both the North and South Poles, while the Earth's orbital axis is the line perpendicular to the hypothetical plane through which the Earth moves as it revolves around the Sun. The angle between these two is known as the Earth's obliquity or axial tilt.
Thus, Precession of Earth's axis causes a axial tilt.

Answers
Answer:
When the organism inherits a mutated gene creating new colored organisms into the population, this can increase diversity. As more organisms inherit the same mutation, the population will become more variated, which can increase the organisms abilities to survive and adapt in a changing environment, and also improve the biological fitness of individuals; resulting in allowing more organisms to reproduce successfully.

SECTION A: DEMOCRACY AND HUMAN RIGHTS 1. HUMAN RIGHTS VIOLATIONS Read the following articles from Teenactiv: Article A Ensuring Equitable Covid-19 Vaccine Distribution in South Africa 50 MARKS South African authorities have an obligation to fully respect the human rights of refugees, asylum seekers, and people without legal documentation within their borders, including their right to health. Excluding or limiting certain groups' access to vaccination based on national origin or residency status would undermine the public interest and public health goal of ending the pandemic. Such a discriminatory policy would also likely further inflame nationalistic sentiments in a country battling to end perennial waves of xenophobic violence. Discrimination based on national origin or residency status would violate South Africa's Constitution and its obligations under the Convention on the Elimination of All Forms of Racial Discrimination (CERD) and the International Covenant on Economic, Social and Cultural Rights (ICESCR). Any differential treatment based on national origin or immigration status can only be justified as non-discriminatory if it pursues a legitimate aim and is proportionate to its achievement. https://www.hrw.org/news/2021/02/03/ensuring equitable-covid-19-vaccine distribution-south-afric By Dewa Mavinga.

1.3. Identify TWO potential negative outcomes if this group were denied their right to receive the Covid-19 vaccine. (2x2) 3
Answers
1.2. Two potential human rights that could be violated in this situation are the right to health and the right to non-discrimination. The right to health is a fundamental human right that includes access to timely and appropriate health care, as well as the underlying determinants of health, such as access to safe and potable water and adequate sanitation, nutritious food, and housing. Discrimination based on national origin or residency status is also a violation of human rights, as it is prohibited by international human rights law.
1.3. Two potential negative outcomes if this group were denied their right to receive the Covid-19 vaccine are the perpetuation of the pandemic and the exacerbation of nationalistic sentiments. By denying certain groups access to vaccination based on national origin or residency status, the pandemic will continue to spread, as these groups will remain susceptible to infection and can continue to spread the virus. Additionally, a discriminatory policy could further inflame nationalistic sentiments, leading to increased violence and discrimination against vulnerable groups within South Africa.
Male organisms are more susceptible to genetic disorders linked to the sex chromosome then female because they have _______, and therefore, the law of dominance doesn’t apply
Answers
Because male creatures contain X and Y chromosomes, which are sex chromosomes, the law for dominance does not apply to them and they more susceptible to sex-related genetic diseases than female species.
Why are sex-related features more prevalent in males than females?Males only inherited one X chromosome, hence they only have one chance to receive the "good" allele because females contain two versions of an x-linked allele whereas males only carry one. Males are more likely than females to exhibit X-linked characteristics.
Why are sex-related genetic diseases exclusively inherited by women?That's because X-linked diseases are typically brought on by a lack of functional copies of a gene found on the X chromosome. Males are born with just one X chromosome. Hence, they just require one malfunctioning .

Thus, since the orange juice is a suspension as long as it contains different sizes of orange pulp particles that cannot be dissolved mostly because of its organic nature.
Tea can be a solution when we place a tea bag in a cup with warm water since just soluble components of tea are successfully dissolved in the water. Moreover, homemade tea based on some plants are fruits may behave as a suspension due to the oraginic particles that are not dissolved in the water yet suspended.
A soda is a solution of some water-soluble compounds, gaseous soluble carbon dioxide and water which are homogeneously distributed in the solution.
Salty water can be a solution if you put some salt in warm or just cold water and wait until it dissolves completely.
Coffee can be also a solution or suspension depending on how it is made, which type of coffee is used and the amount of coffee added to the hot water.
