Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

The point where separation of the DNA occurs is called the replication fork.
True
False
Answer:
True
Explanation:
The point where the separation of the DNA occurs is called the replication fork. Therefore, it is true.
What is a replication fork?The DNA double helix of a cell has been unwound and split into the replication fork, which is where DNA polymerases and other enzymes can work.
DNA helicases unwind DNA at locations known as origins during DNA replication, where synthesis will begin. The replication fork, so named because the two strands of DNA seem forked as they are unzipped apart, is a structure that is created while DNA helicase proceeds to unwind the DNA.
A replication bubble is created when the circular bacteria chromosome's double-stranded DNA is opened at the point of replication. A replication fork, a Y-shaped junction where double-stranded DNA is split into two single strands, is present at each end of the bubble. Therefore, it is true.

In these experiments, researchers are taking brain cells from patients with disorders like autism and schizophrenia and using them to grow tissue which produce organoids miniature versions of the body's organs. How might studying these brain organoids help patients with these disorders?
Answer:
It could help in knowing in detail the etiology of the pathology, in order to evaluate the prognosis and its most appropriate treatment.
Explanation:
When cultivating the cells, it is possible to observe if they worsen the pathology before certain means or stimuli, or even the consumption of drugs and derivatives.
Not only with that, the beginning of this pathology is called etiology, when the etiology is studied in detail, the ideal treatment is the one that is determined, since the focus to attack is known so that these pathologies do not advance or even revert .

Which of the following scenarios can be classified as a negative feedback loop?
a increase in blood pressure to reduce heart rate
b increase in testosterone to help increase a fight-or-flight response
c increase in oxytocin caused by increased contractions
d increase in platelet production to help increase blood clotting
Answer:
The scenario that can be considered an example of a negative feedback loop is increase in platelet production to help increase blood clotting (option d).
Explanation:
Negative feedback loop is what occurs when a change occurs in the body, producing a response that decreases or stops that change, with the intention of maintaining homeostasis.
When there is a wound that produces bleeding, a series of mechanisms are activated, the coagulation cascade, which promotes the release of factors that allow the formation of clots. The increased release of platelets implies negative feedback because it helps to stop the change that occurs in the body, the loss of blood, through the formation of clots.
One thing that can cause confusion is the fact that this response also involves positive, though limited, feedback that promotes the production of clotting factors and platelets to increase clot formation. What really happens is that the positive feedback promotes the general feedback, which is the negative feedback: clot formation to stop the bleeding, restoring homeostasis.
The other options are not correct because:
a. Increase in blood pressure to reduce heart rate is not possible.
b. In the fight and flight response the hormones involved are cortisol and adrenaline, not testosterone.
c. Increased oxytocin in response to uterine contractions is positive feedback.

During photosynthesis, plants produce ___ and oxygen from the ___ of solar energy, water, and carbon dioxide.
Answer:
1. Glucose
2. Conversion
Explanation:
During photosynthesis, plants produce glucose and oxygen from the light of solar energy, water, and carbon dioxide. This process is called photosynthesis.
What is photosynthesis?Photosynthesis is a process that takes place in green plants because they have chlorophyll pigment. Chloroplast is the organelle that is present in green plants. This organelle has chlorophyll pigment that carries out the photosynthesis process.
In photosynthesis, water is taken from the soil, carbon dioxide is taken from the atmosphere, and with the help of sunlight, glucose and oxygen are formed in the chloroplast. Due to this, plants are called producers.
Photosynthesis releases oxygen into the atmosphere, which is required by all living organisms. Organisms take in oxygen and release carbon dioxide into the environment. This is called the respiration process.
In the grassland ecosystem, the plants do photosynthesis. In the ocean's ecosystem, phytoplankton do photosynthesis. Different consumers depend on these producers for food.
Hence, plants produce glucose and oxygen from solar light energy, water, and carbon dioxide.
