What happens next? (Think about the carbohydrates, proteins and fat in our sandwich

Answers

Answer:

Explanation:

After amylase act on carbohydrates, the chyme pass through the oesophagus down to the dudoneum in the small intestine. Amylase also continue to break it down into disacharrides and enzymes like maltase, sucrase and lactase are released to further break it down into maltose, sucrose, and lactose then finally glucose, a way it can be absorbed easily by the epithelial walls.

The digestion of lipids and protein begin in the dudoneum of small intestine.

Trypsin act on protein and break it down to peptides. Peptidase is then released and break it to single chain peptides bond. In the small intestine, dipeptidases break it down into amino acids easily absorbed by the epithelial walls.

The bile in the gall bladder produce enzyme called lipases which breakdown lipids and make it to undergo emulsification.

A red blood cell leaving the left ventricle of the heart would take which pathway to reach the facial artery?

Answers

Answer:

Red blood cell arrives from the inferior vena cava into right atrium before it passes through the tricuspid valve into right ventricle. It then passes through the pulmonary valve into pulmonary artery before travelling through the lungs and back into the heart, this time the left atrium via the pulmonary vein.

Explanation:

hope this helps

The pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery

The arch of the aorta can be considered as the peak of the ascending aorta.

The brachiocephalic trunk refers to the second branch to arise from the aorta.

The right common carotid artery arises as a branch of the brachiocephalic trunk of the aortic arch.

The facial artery is a branch of the external carotid artery that supplies blood to the muscles and skin of the face.

In conclusion, the pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery.

Answers

Answer:

3/32 ttyyR-  

Explanation:

Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual

Parentals) TtYyRr      x      TtyyRr      

Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)

                 TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)

We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:

Shot → ttRound → RR or RrGreen → yy

⇒ Parent one can provide gametes tyR and tyr

⇒ Parent two can provide gametes tyR and tyr

(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =

2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =

1/32 ttyyRR + 2/32 ttyyRr =

3/32 ttyyR-          

The branch of science which deals with the gene and inheritance is called biology.

The correct answer is 3/32.

When a parent has 3 characters and crosses with other parents which have a 3 character is called a trihybrid cross.

In this question, the genotype of the parent is given as follows:-

Mother - TtYyRrFather - TtyyRr

The gametes formed by the parents is as follows:-

TYR, TYr, TyR, Tyr,  tYR, tYr, tyR, tyr is gamete of motherTYR, TYr, TyR, Tyr,  tYR, tYr, tyR, tyr is gamete of father.

According to the law of inheritance it stated that the each gamete can fused with any gamete to increase the chances of variation.

Hence, after the crossing the number of offspring will form is 32.

Therefore the offspring which has a short plant with a round green seed is 3/32.

Hence, the correct answer is 3/32.

Explanation: But to answer the "Earth warming up" question, I'd have to say that for over millions of years, Earth's climate has warmed up and cooled down many times. However, today the planet is warming much faster than it has over human history. Global air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the last century. However, other evidence suggests that the period of 2,000 to 3,000 million years ago was generally colder and more glaciated than the last 500 million years.

Describe the metabolic pathways in the monarch butterfly that take advantage of milkweed nectar to convert it into an energy currency.

Answers

Answer:

Metabolic pathways in monarch butterflies are as follows:

GlycolysisKreb's cycleOxidative phosphorylation

Explanation:

They convert sugar which they obtain from nectar into fats that they store as source of energy. Monarch have a little layer of fatty tissues which aid in conversion of Sugar in to fat.

They consume the stored fat during reproduction. A lot of fat is eventually converted to eggs and some of it is used to provide energy just to sustain the reproductive butterflies.

During winter season, when their metabolic is low they consume energy by converting stored fat into sugar called Trehalose.  The conversion of fat also releases little water which help them to survive during winter.

1) Glycolysis:

Glucose is phosphorylated by hexokinase enzyme to give glucose-6phosphate. This glucose-6-phosphate enters into glycolysis and is broken down into two molecules of pyruvate in a series of ten reactions. During glycolysis net two molecules of ATP are synthesised per glucose molecule. Moreover, two molecules of NADH+H+ are also synthesised. In aerobic organisms like monarch butterfly the pyruvate is again oxidised to give acetyl-CoA in the mitochondria. The enzyme responsible for this oxidation is Pyruvate Dehydrogenase Complex. This reaction occurs in the mitochondrial matrix. Here one CO2 molecule is removed from the pyruvate and one NADH is produced.

2. Kreb's Cycle:

The acetyl-CoA formed enters into the Kreb's cycle by condensing with oxaloacetate. In Kreb's cycle acetyl-CoA is completely oxidised to give carbon dioxide in eight enzymatic reactions. During Kreb's cycle NADH, FADH2 and one molecule of GTP is produced and oxaloacetate is regenerated to continue the cycle.

3. Oxidative Phosphorylation:

The NADH produced in the glycolysis and Krebs cycle and FADH2 produced during Krebs cycle are now oxidised to generate proton gradient across the inner mitochondrial membrane. This gradient is generated when the electrons from the reduced NADH and FADH2 are transported in the electron transport chain(ETC), and are finally accepted by the oxygen.

When the electrons are picked up by the complexes of the ETC they pick protons from the matrix. When the electrons are transferred to next complex the protons are transferred to the inter-membrane space. In this way a proton gradient is generated across the innner membrane of the mitochondria.

This proton gradient is used by the complex V of the ETC. This complex is the enzyme ATP Synthase. This enzyme complex is located in the inner mitochondrial membrane. When the protons flow back from the inter-membrane space into the matrix along the concentration gradient , they move through the channel in the ATP Synthase Complex. When these protons flow through this complex it catalyzes the phosphorylation of ADP to give ATP, the energy currency.

The fructose component of the sucrose is first converted into glycogen and then broken down to give glucose-1-phosphate, which enters into glycolysis.

Sucrose cannot enter the pathway of glycolysis as such. It is first hydrolysed to glucose and fructose as described above along with the path way.

Explanation:

Kwashiorkor is a severe form of malnutrition. It's most common in some developing regions where babies and children do not get enough protein or other essential nutrients in their diet. The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema). (Source: Kwashiorkor - NHS)

Hopefully this helps.

Kwashiorkor is a serious condition that can happen when a person does not consume enough protein. Severe protein deficiency can lead to fluid retention, which can make the stomach look bloated.

Kwashiorkor is most common in children, especially if they do not have access to adequate nutrition soon after they stop breastfeeding. If a child experiences kwashiorkor, they need immediate medical attention.

Other terms for kwashiorkor include:

Answers

Answer:

W) filamentous actin

Explanation:

T cells are a type of white blood cells (leukocytes) that play a fundamental role in the immune system by determining the specificity of the immune response to specific antigens. In T cells, the remodeling of the actin cytoskeleton is critical for the movement of these cells through different tissue environments and for adjusting their behavior during the scanning of antigen-presenting cells. The actin cytoskeleton acts as a physical platform for intracellular signaling events that occur at the immunological synapse formed between a T cell and an antigen-presenting cell, thereby contributing to T cell activation.

What is a way to prevent eutrophication?

Answers

Answer:

Agricultural fertilizers are one of the main human causes of eutrophication. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The use, or overuse, of fertilizers can cause these nutrients to runoff of the farmer's field and enter waterways. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

The following is a list of methods that can be used to control eutrophication:

planting vegetation along streambeds to slow erosion and absorb nutrients.

controlling application amount and timing of fertilizer.

controlling runoff from feedlots.

The best, easiest, and most efficient way to prevent eutrophication is by preventing excess nutrients from reaching water bodies. This can be done in a number of ways, the simplest of which is just being aware of the chemicals and fertilizers that we are using.
