James needed to have his hernia surgically repaired. This can be done through laparoscopic surgery. The surgeon must cut through to the herniated area and put a Teflon mesh underneath the hernia to close it off and provide more support to the area. Use your knowledge of anatomy to select the correct sequence of structures that would be cut for this procedure. Make sure you select the structures in the order they would be cut by the surgeon.
Answer:
The structures that the surgeon will cut to place the Teflon mesh from external to internal are:
Skin,
hypodermis,
subcutaneous fat,
the external oblique aponeurosis,
the internal oblique,
the transverse abdominal,
the peritoneum.
Explanation:
For the surgeon to put the Teflon mesh underneath the hernia, the professional has to cut the most external organ, which is the skin, with all its layers, epidermis, dermis, and hypodermis. Underneath this tissue is the subcutaneous fat, which protects the muscles, regulates the temperature, and stores energy. Subcutaneous fat is different in every person. Some can have a lot of it and others a thin layer. The next cut will be on aponeurosis, which is a tissue that surrounds muscles. Then we have the internal abdominal oblique, which is in the anterior area of the abdomen. Below it, it is the transverse abdominal, and then the peritoneum, which is the tissue that holds the organs. In a hernia, it has a hole where the organs push through. So, the surgeon has to put a Teflon mesh to close it.
does lemon juice have more or less H+ ions than it has OH- ions? explain
Acids are substances that provide hydrogen ions (H+) and lower pH, whereas bases provide hydroxide ions (OH–) and raise pH. The stronger the acid, the more readily it donates H+. For example, hydrochloric acid and lemon juice are very acidic and readily give up H+ when added to water. ( source : https://courses.lumenlearning.com/wmopen-nmbiology1/chapter/the-ph-scale/ )

The main source of energy for all life comes from
Answer:
the sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

When you breathe in oxygen, what happens? How does oxygen get to the tissues of your body? (USE YOUR OWN WORDS)
Answer:
When you breathe in oxygen, your diaphragm pushes against itself and pulls downwards. The muscles between the ribs pull upwards. The oxygen gets into the tissues by being helped by red blood cells and has a pigment that collects four oxygen molecules. It forms into a thing known as oxyhaemoglobin and the molecules are taken to other singular cells in the body tissue, releasing its contents.

Which processes are involved in the chloroplast of a plant cell?
Photosynthesis Cellular respiration
Aerobic Respiration Anaerobic Respiration
Glycolysis Electron Transport
Krebs Cycle Electron Transport Chain
Light Dependent Reaction Calvin Cycle
Answer:
Chloroplast absorbs sunlight and it is used to make feed for the plant together with water and carbon dioxide gas. Chloroplasts are used to generate the free energy stored in ATP and NADPH via a photosynthesis process.
Explanation:
The site of photosynthesis action is chloroplast within a plant cell consisting of two chlorophyll molecules (PS1 and PS2), which have been embedded in the thylakoid membranes. The chloroplast consists of two chlorophyll molecules (photosynthetic pigments responsible for the green color of chloroplast). Each chlorophyll molecule absorbs light, caused to depart the chlorophyll molecules. This absorbs two electrons from each phenotype. PS2 electrons pass through the transportation chain for electron carriers, a series of redox reactions that release the energy used to synthesize ATP via Photophosphorylation/Chemiosmose (as the H+ ions diffuse through the stalked particles ATP, which changes the shape and catalysts, the electrochemical gradient diffuses down through the stalky particle ATP synthase).
Then these electrons replace the electrons lost in PS1. PS2 electron is replaced by photolysis electron, which when light strikes chloroplast, splitting the water into oxygen gas, H+ ions, and electron enzymes in the thylakoid space are catalyzed. The PS1 electrons combine to create NADPH with H+ ions and NADP (reduced NADP). These are the light-dependent photosynthetic reactions in chloroplasts. In the light-independent reactions, the NADPH and ATP are created. A pile of thylakoids is known as granum.
The light-independent processes take happen in the stroma. This is the site of carbon fixation; CO2 reacts with RUBP to generate GP (glycerate-3-phosphate) which is catalyzed by the enzyme RUBISCO (the most abundant enzyme in the world) (the most abundant enzyme in the world). The NADPH and ATP from the light-dependent processes convert GP to GALP (glyceraldehyde 3-phosphate). Two out of every 12 GALP molecules produced are used to synthesize glucose that can be employed either in breathing or in cellulose-forming condensation polymerization to add extra strength to the planted cell wall. The other GALP molecules are returned to RUBP.

Al cruzar 2 moscas negras se obtiene una descendencia formada por 216 moscas negras y 72 oscuras blancas. A) Razone el cruzamiento y determine fenotipo y genotipo.
Answer:
Fenotipo: Moscas negras y moscas blancas.
Genotipo: Nn y nn.
Explanation:
Sabemos que al cruzar dos moscas un pequeño porcentaje de su descendencia es blanca y la mayoría negra. Por ende, hay dos alelos distintos para el color, uno codifica para moscas de color negro y el otro para las de color blanco. Como la mayoría de la descendencia es negra, el gen domiante es el negro, a este lo denominaremos con la N y al recesivo con la letra n.
Para que haya moscas blancas, las dos moscas que se cruzan tienen que ser Nn, es decir, su genotipo tiene que ser heterocigoto. Podemos verificar esto con un cuadro de Punnett:
║N ║n
N║NN║Nn
n║Nn ║nn
Con el cuadro de Punnet vemos que la descendencia tiene los genotipo, es decir, los genes que un ser tiene, Nn y nn. El fenotipo, es decir, lo que podemos ver de los genes, sera moscas de color negro y moscas de color blanco.
Como el gen dominante es el negro, cualquier mosca con este gen expresara este color y solo las moscas con genotipo h0m0cigoto (nn) expresaran el color blanco.
is it more beneficial for humans to undergo sexual reproduction than asexual reproduction?
Answer:Advantages and disadvantages of sexual and asexual reproduction
Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents.
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population
Examples in the natural world
Bacterial reproduction
Bacteria, such as E. coli, reproduce asexually. An advantage of this is that they can produce many bacteria very quickly. A disadvantage is that all of the bacteria are genetically identical. If an antibiotic was used on the bacteria, then all of them would die. The population would be wiped out. The only way for variation to be introduced into the population is by random mutation.
Rabbit reproduction
Most animals reproduce sexually, for example, rabbits. The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage. If a disease were to hit the rabbit population, then perhaps not all of the rabbits would be affected because of the variation in the population. This means that some individuals would survive and be able to reproduce and generate more offspring.
Asexual and sexual reproduction in fungi
Some fungi are able to reproduce both sexually and asexually. Fungi reproduce using spores which they release into the environment. A new fungus will grow from the spore. The Coprinus cinereus fungus can produce spores by sexual reproduction to help create variation in the species. This method of reproduction is advantageous when the environment is changing because the variation introduced leads to an increase in the probability that a variant that can deal with the change. Coprinus cinereus also produces spores by asexual reproduction. These spores can be produced quickly and in large numbers to enable many individual fungi to develop. A disadvantage of these spores is that they generate offspring that are unlikely to be resistant to unfavourable conditions because they are all genetically identical.
Common inkcap mushrooms
Some mushrooms can carry out both asexual and sexual reproduction depending on their environment

i) Explain how the biochemical reaction can still occur if the blood sugar level is lower
than the normal range.
Answer:
To produce energy from available sugar.
Explanation:
The biochemical reaction can still occur if the blood sugar level is lower than the normal range because energy is needed by the body for its activities. The biochemical reactions helps in producing energy in the form of ATP that is needed by the body for its different activities. The lower level of sugar in the blood does not fulfil the needs of body but provides some energy for it so that's why the body produces energy from available sugar present in the body.
