How are photosynthesis and cellular respiration connected as a cycle?
Answers
Answer:
Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off).
glucose + oxygen + (energy) → carbon dioxide + water
C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O
Respiration is the process of producing energy from glucose. It uses glucose and oxygen to give water, carbon dioxide and energy (thus making it exothermic).
carbon dioxide + water + energy → glucose + oxygen
6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2
As you can see from the equations, they are essentially the reverse of each other.
Another difference is how they are used. Respiration occurs in the mitochondria of all living cells, whereas only plants photosynthesize.
In plants, they make their own glucose using the sun's energy, then respire to allow them to use the glucose for the energy they can use. The glucose can also be stored and used in many other ways other than in respiration.

what are the muscles involved in inhalation and exhalation? 2. cobra venom contains a neurotoxin that prevents the brain from telling the diaphragm when to contract. how would this impact the respiration of an individual bit by a cobra? if there is no cobra anti-venom, what would need to be done for a cobra bite victim to survive?
Answers
Inhalation and exhalation are controlled by respiratory muscles. Cobra venom's neurotoxin can cause respiratory failure, requiring immediate medical attention for survival.
Inhalation and exhalation are controlled by the respiratory muscles, including the diaphragm, intercostal muscles, and accessory muscles. During inhalation, the diaphragm contracts, flattening and moving downwards, while the intercostal muscles expand the rib cage.
This increases the volume of the chest cavity, causing air to rush into the lungs. During exhalation, the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size, and the air is pushed out of the lungs.
The neurotoxin in cobra venom prevents the transmission of nerve impulses from the brain to the diaphragm, resulting in respiratory failure. This can lead to severe breathing difficulties, eventually leading to respiratory arrest and death. If anti-venom is not available, immediate medical attention is required.
The victim may need to be placed on a ventilator to assist with breathing, and supportive measures such as oxygen therapy and administration of fluids may be required to stabilize the individual. Additionally, the bite wound should be cleaned and immobilized to prevent further spread of venom. Seeking medical attention immediately is crucial for the victim's chances of survival.

a. A lion has eyes in the front of its head.
b. A deer has eyes on the sides of its head.​
Answers
a. A lion has eyes in the front of its head because it is a predator.
b. A deer, on the other hand, has eyes on the sides of its head because it is a prey animal.
a. Lion has eyes in the front of its head because it is a predator. meaning it hunts and kills its prey. This kind of hunting requires depth perception, which is only possible with two forward-facing eyes. Having eyes on the front of the head also allows for a wider field of vision, which helps the lion to locate prey more easily.
b.A deer, on the other hand, has eyes on the sides of its head because it is a prey animal, meaning it is hunted by other animals. This position of the eyes allows for a wider field of vision, giving the deer a better chance of spotting a predator before it gets too close. Additionally, having eyes on the side of the head provides the deer with a wider range of vision, allowing it to monitor its surroundings for predators while grazing. This adaptation is beneficial for survival purposes as it helps the deer to stay alert and avoid danger.

excess amounts of insulin in the blood will have what effect on the number of insulin receptors present?
Answers
Excess amounts of insulin in the blood can lead to a decrease in the number of insulin receptors present on the surface of cells.
Insulin аnd glucаgon аre hormones thаt help regulаte the levels of blood glucose - аkа sugаr - in our body. Glucose comes from the food you eаt аnd moves through your bloodstreаm to help fuel your body. Insulin controls whether sugаr is used аs energy or stored аs glycogen. Glucаgon signаls cells to convert glycogen bаck into sugаr. Insulin аnd glucаgon work together to bаlаnce your blood sugаr levels, keeping them in the rаnge thаt your body requires.
Decreasing the number of insulin receptors present on the surface of cells occurs due to a process called downregulation, where the cell reduces the number of receptors in response to high levels of insulin. Over time, this can lead to insulin resistance, where the body requires more insulin to achieve the same effect, and can contribute to the development of type 2 diabetes.

Sally has Cystic Fibrosis (recessive autosomal disorder) represented as cc. Her mother claims that she does not have it and blames it on Sally's father who also claims that he is not. What can be the genotype of both the parents?
Answers
If Sally has Cystic Fibrosis (CF) represented as cc, and CF is a recessive autosomal disorder, we can determine the possible genotypes of her parents.
Since CF is a recessive disorder, an affected individual must have two copies of the CF gene (c) in their genotype. Therefore, Sally's genotype is cc.
If Sally inherited one copy of the CF gene from each parent, then both of her parents must be carriers of the CF gene. A carrier is an individual who has one copy of the CF gene (c) and one copy of the normal gene (C). Carriers do not have the disorder themselves but can pass the CF gene to their children.
So, based on the given information, the possible genotypes of the parents could be:
- Sally's mother: Cc (carrier)
- Sally's father: Cc (carrier)
Both parents would appear unaffected because having only one copy of the CF gene does not cause the disorder. However, when both parents are carriers, there is a 25% chance of their child inheriting two copies of the CF gene and having the disorder (cc), as in Sally's case.

Answers
Answer:
Independent variable: water given to the plantsDependent variable: height of each plantExplanation:
The independent and the dependent variables are the two principal factors needed in an experiment.
• Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The independent variable changes or is controlled and modified in the experiment to analyze how the other variable responds to it. The researcher can change it to see what changes it implies in an object, process, trait, or anything that depends on them, to study its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the researcher manipulates the water given to the plants. One plant receives water that has been microwaved and the other plant receives regular tap water.
• Responding variable: Refers to the dependant variable. The dependent variable is the one that is being investigated, studied, and measured. It represents a quantity of something which value depends on how the independent variable is modified. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, the dependent variable is the height of each plant after 2 weeks of treatment.
• Controlled variable: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example these are the light and pots.

Which of the following statements describes a dimeric allosteric enzyme following the concerted model?
a) The binding of the substrate to one subunit affects the activity of the other subunit.
b) The binding of the substrate to one subunit does not affect the activity of the other subunit.
c) The enzyme is composed of multiple subunits that work independently of each other.
d) The enzyme is not affected by the binding of the substrate.
Answers
The correct statement that describes a dimeric allosteric enzyme following the concerted model is: a) The binding of the substrate to one subunit affects the activity of the other subunit.
In the concerted model of allosteric regulation, the binding of a substrate or ligand to one subunit of the enzyme causes a conformational change that affects the activity of the other subunits. This model suggests that the enzyme can exist in two conformations (e.g., tense or relaxed) and the binding of a substrate stabilizes one conformation over the other. This results in the simultaneous change in the activity of all subunits.
Allosteric enzymes following the concerted model are characterized by the binding of the substrate to one subunit, which in turn influences the activity of the other subunit.

Which feature is responsible for the superior acuity of the fovea?
a. Lack of retinal blood vessels
b. Higher density of ganglion cells
c. Increased concentration of rods
d. Presence of the inner nuclear layer
e. Maximum photon scattering before reaching the photoreceptors
Answers
b. Higher density of ganglion cells.
The superior acuity of the fovea, which is the central region of the retina responsible for high-resolution vision, is primarily attributed to the higher density of ganglion cells. Ganglion cells are the output neurons of the retina that transmit visual information to the brain. In the fovea, the ganglion cells are densely packed, allowing for a more direct and precise relay of visual signals to the brain, resulting in increased visual acuity.
The other options provided are not directly responsible for the superior acuity of the fovea. While the lack of retinal blood vessels (a) reduces potential interference with light passing through the fovea, it is not the main factor contributing to acuity. The increased concentration of rods (c) is actually lower in the fovea compared to the periphery, as the fovea is specialized for high-resolution color vision. The presence of the inner nuclear layer (d) and maximum photon scattering before reaching the photoreceptors (e) are not directly related to foveal acuity.

Among pea plants, we see more peas with smooth pods than with constricted pods. If a plant with constricted pods is mated with a plant with smooth pods, the offspring have smooth pods. When the offspring mature, and two of them are mated, they have a 25 percent chance of producing offspring with constricted pods. Identify the offspring with homozygous alleles for the smooth pod trait.
Answers
Based on the information you provided, I can explain the concept of homozygous alleles for the smooth pod trait.
In the given scenario, if a plant with constricted pods (which is likely heterozygous for the trait) is mated with a plant with smooth pods (which is likely homozygous for the trait), the resulting offspring with smooth pods would be heterozygous for the trait.
Homozygous alleles refer to having two identical alleles for a particular gene. In this case, if the offspring with smooth pods from the initial mating are mated with each other, there is a 25 percent chance that they will produce offspring with constricted pods. This suggests that the parents must have carried a recessive allele for the constricted pod trait.
