One section of a strand of dna has the bases sequence agattc. what is the base sequence on the other strand?
Final answer:
To determine the sequence of the complementary DNA strand, one must use the base pairing rules: A pairs with T, and C pairs with G. Given the sequence 5'-AGATTC-3' on one strand, the complementary sequence is 3'-TCTAAG-5'.
Explanation:
The subject of this question is Biology, specifically focusing on genetics and the structure of DNA. When given a sequence of one DNA strand, it's crucial to understand base pairing rules to determine the sequence of the complementary strand. DNA strands are antiparallel; they run in opposite directions. Hence, when one strand has the sequence 5'-AGATTC-3', we look at the base pairing rules where adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G) to find the complementary sequence. Using this information, the sequence of the complementary strand corresponding to 5'-AGATTC-3' would be 3'-TCTAAG-5', reading in the antiparallel direction.

The return of a cardiac muscle cell to its preexcitation resting state is called:
The return of a cardiac muscle cell to its resting state following excitation is called repolarization, which restores the cell's resting membrane potential and occurs before the refractory period.
The return of a cardiac muscle cell to its preexcitation resting state is known as repolarization. This process occurs after depolarization, where the membrane potential is restored to a negative value inside the cell. During repolarization, voltage-gated sodium channels close, and potassium channels maintain their conductance, helping to bring the cell back to its resting state. The resting membrane potential is maintained by the sodium-potassium ATPase, which pumps sodium out of the cell and potassium into the cell, maintaining the ionic gradient necessary for the next action potential. Following repolarization is the refractory period, a time during which the cell cannot generate another action potential, allowing for a controlled rythm.

The asthenosphere occupies a majority of the mantle.
T.
F.
Answer:
true
Explanation:
bc
Answer:
False
Explanation:
The total depth of mantle is 1800 to 2900 kilometers. Mantle accounts for 80% of the total earth and Iit is made up of two layers – lithosphere and Asthenosphere. Asthenosphere lies at the depth of 80 and 200 kilometers which is just 4.4% to 6.89 % of the total depth of mantle. From this it can be visualized than asthenosphere do not constitute even half of the mantle and therefore the statement “The asthenosphere occupies a majority of the mantle” is false

When milgram modified his shock experiment so that the teacher could see the learner, the level of obedience
a. increased greatly.
b. increased slightly.
c. decreased.
d. remained unchanged?
Being able to see the consequences of one's actions can decrease obedience to authority. Therefore, option (C) is correct.
What is milgram shock experience?In the original Milgram shock experiment, the teacher (the participant) was instructed to administer increasingly intense electric shocks to a learner (an actor who was pretending to be in pain) every time the learner made a mistake on a memory task. The experiment was designed to investigate obedience to authority. In a modified version of the experiment, the teacher was able to see the learner and observe their reactions to the shocks.
The level of obedience in this condition was found to be lower compared to the condition in which the teacher could not see the learner. This suggests that being able to see the consequences of one's actions can decrease obedience to authority.

A pregnant client's last menstrual period was on february 11. a physical assessment on july 18 should reveal the top of the fundus to be where?
The top of the fundus during a pregnancy check-up at 23 weeks, calculated from the LMP of February 11 and the physical assessment date of July 18, should be slightly above the umbilicus or belly button.
The question asks about the position of the top of the fundus during a pregnancy check-up. The last menstrual period (LMP) was on February 11, and the physical assessment is on July 18. Using Naegele's rule, which adds 7 days to the LMP, then subtracts 3 months, and adds a year, we can estimate the due date to be around November 18. This makes the pregnancy approximately 23 weeks along by July 18. Typically, the top of the fundus at this stage should be slightly above the umbilicus (belly button). In general, from 20 weeks of pregnancy, the top of the uterus, or the fundus, is expected to grow about 1 cm per week, so it should be at or a little above the umbilicus during a 23-week pregnancy assessment.

The working for water program helps conserve water by employing individuals to remove invasive plants. True or false
The given statement is True.
The workers working for the water programs are employed to remove the invasive plants to conserve water.
A large number of invasive plants or trees might absorb the water present underground which can lower down the water table.There are some plants present in the nature who have deep roots and they have the ability to get water from deep down the ground.
This will decrease the amount of water available for the human consumption.These kind of plants and trees should be removed so as to conserve water.

Answer:
Why does the moon look different at different times of the month
The Moon appears differently throughout the month due to its monthly cycle of phases as it revolves around Earth. This results in changes in the visible part of the Moon's illuminated hemisphere and prominent changes in the visibility of its topographic features depending on the angle of sunlight hitting it.
Explanation:The Moon looks different at different times of the month due to its monthly cycle of phases which results from the changing angle of its illumination by the Sun. This is not due to the Moon's rotation but its revolution around the Earth. Because it takes about 30 days to orbit Earth, we observe this as a shift in the Moon's visible position in the sky each day and a change in the visible portion of the Moon's illuminated hemisphere.
When the Moon is in the same part of the sky as the Sun, we see it as a new moon where the bright side is turned away from us. However, as the Moon revolves around the Earth, we start to see more of its illuminated side, resulting in a crescent moon that grows into a full moon as the Moon moves further away from the Sun's position. After the phase of the full moon, the Moon's visible light begins to decrease, transitioning back to the new moon stage.
Fascinatingly, the way sunlight hit's the Moon also impacts the visibility of its topographic features. When the Moon is at full phase, sunlight shines directly on it, creating a flat lighting scenario that doesn't cast shadows, thereby making it difficult to see the craters and mountains on the Moon. However, near first or third quarter of the moon's cycle, sunlight hits the moon at an oblique angle, casting shadows and distinctly revealing the Moon's topographic features.

Which model of eating disorders includes a "core pathology"?
The model of eating disorders that includes a "core pathology" is the Cognitive-Behavioral Model (CBT) of eating disorders.
According to CBT, an individual's thoughts, beliefs, and attitudes about body image, weight, and food are dysfunctional. This underlying disease causes and maintains disordered eating and skewed cognitions.
Eating disorders are characterised by negative and illogical attitudes about body form, weight, and food, which lead to maladaptive behaviours such restrictive eating, binge eating, and purging, according to CBT. Disordered eating is caused by these problematic ideas.
CBT uses cognitive restructuring to uncover and correct these incorrect attitudes and beliefs, improving food, body image, and self-esteem. CBT targets the core disease to modify behaviour and help eating disorders recover.

Earth's oceans contain many dissolved elements like calcium, sodium, and chlorine. These elements plus several others combine to form the salts in the oceans.
What is a major source of calcium and sodium in oceans?
A) air pollutants
B) gases from active volcanoes
Eliminate
C) minerals dissolved in aquifers
D) weathering and erosion of rocks
The right answer is D) weathering and erosion of rocks.
Sodium (Na) exists mainly in the oceans in the form of sodium chloride NaCl. This salt is derived from mines or saline rocks, by erosion of rock evaporite salt called rock salt or halite.
Calcium (Ca) exists mainly in the form of limestones, which are sedimentary rocks, just like sandstones or gypsums, easily soluble in water (see karst), composed mainly of calcium carbonate CaCO3, but also magnesium carbonate MgCO3.
