A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

What is cellular respiration?

Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.

Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.

Disorders that interfere with cellular respiration often impair one or more of the enzymes necessary for it, such as succinyl-CoA synthase or pyruvate kinase.

Therefore, A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

What is the difference between a hepatic duct and a hepatic vein?​

Answers

Explanation:

The liver is connected to two large blood vessels, the hepatic artery and the portal vein. The hepatic artery carries blood from the aorta to the liver, whereas the portal vein carries blood containing the digested nutrients from the entire gastrointestinal tract, and also from the spleen and pancreas to the liver.

The hepatic veins carry oxygen-depleted blood from the liver to the inferior vena cava. They also transport blood that has been drained from the colon, pancreas, small intestine, and the stomach, and cleaned by the liver. These veins originate from the core vein of the liver lobule, but they do not have any valves.
The hepatic duck: A duct that carries bile from the liver into the common bile duct which conveys it to the duodenum (the upper part of the small intestine).

See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size

Answers

Answer:

The correct answer is ''the total amount of energy an animal uses in a unit of time''

Explanation:

The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.

CLAY PARTICLES DO NOT SETTLE DOWN EASILY DURING THE PROCESS OF SEDIMENTATION. CAN YOU SUGGEST ONE METHOD TO MAKE THEM HEAVIER AND THUS HELP IN SEDIMENTATION? Name the method and the chemical

Answers

Answer:

Coagulation by additionmof chemicals such as aluminium sulfate also known as alum will help in sedimentation of clay particles.

Explanation:

Clay particles are very small particles found suspended water obtained from streams and rivers for township supply. They have weak electrical negative charges on their surfaces which when they approach one another, they repel each other thus making it almost impossible for clay particles to settle out of suspension.

Because of this, prior to the sedimentation step, a chemical process known as coagulation is required. In this process, certain chemicals called coagulants, are added to the water to bring the difficult-to-settle suspended particles such as clay particles together into larger, heavier masses of solids called flocs. They do these by interfering with the repulsive forces between the particles, thus allowing them to clump together into flocs. The most commonly used coagulant used for water purification is aluminium sulfate or alum. Other chemicals that are also employed in coagulation include ferric sulfate and sodium aluminate.

A pair of butterflies reproduces and has one thousand offspring. All one thousand of the offspring have the alleles Aa. What is the most likely combination of alleles (genotype) for each parent? Explain your answer.

Answers

Answer:

It is expected that each parent is homo-zygous for each trait (i.e., one parent has genotype AA and the other parent has genotype aa)

Explanation:

An F1 hybrid is the first filial generation of the progeny of distinctly different parental types. In this case, it is expected that each parent is homo-zygous for each trait, thereby 100% of all offspring will have genotype Aa (i.e., parental cross: AA x aa >> F1 = 100% Aa). On the other hand, in a cross where one parent is heterozygous for the trait (Aa) and the other parent is homo-zygous (either AA or aa), only 50% of all offspring will have genotype Aa.

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.

=============================================

For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.

Recall that

distance = rate*time

we can rearrange things to say

rate = distance/time

So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.

----------

So,

rate = distance/time

rate = (260 meters)/(180 seconds)

rate = (260/180) meters per second

rate = 1.44 meters per second, which is approximate

I'm rounding to 3 sig figs.

When 2 or more organisms compete for the same resource there can be a variety of outcomes. What would be one of those outcomes?

Answers

Answer:

The biology branch deals with the relations between and physical environment of organisms.

Explanation:

The principle of competitive exclusion states that if two species occupy the same niche, they cannot exist together (competing for identical resources). Two species whose niche overlap can evolve to have different niches through natural selection, resulting in the distribution of resources.

In ecology, interspecific competition is a form of competition where individuals from different kinds compete in an ecosystem for the same resources (e.g. food or space)... There may be interspecific competition if people of two separate species share a limited resource within a single area.

During his trip on the HMS Beagle, Darwin found that ______________.

B fossils found on a particular continent were clearly not related to the plants and animals living on that continent today.
C plants and animals were similar on every continent and in every type of region.
D plants and animals living on one continent seemed more closely related to each other, than to plants and animals living in similar regions on other continents.

Answers

Answer:

Option D

Plants and animals living on one continent seemed more closely related to each other than to plants and animals living in similar regions on other continents.

Explanation:

From Darwin's discoveries, he noticed that there was a strong relationship between the environment and the characteristics of the living organisms present there.  He proposed that the environmental conditions affected the development of certain traits in organisms present there, in their quest for survival and adaptation.

These traits were passed down from parents to offspring, producing a population of organisms with similar character traits found around the same geographical location (continent in this case)

b. short strands of DNA are contained in chromosomes inside the nucleus of a cell.
c. DNA consists of two strands of nucleotides joined by hydrogen bonds.
d. every DNA nucleotide contains a sugar, a phosphate group, and a nitrogen base.

Answers

Answer:

short strands of DNA are contained in chromosomes inside the nucleus of a cell.

Explanation:

DNA is an acronym for deoxyribonucleic acid. It is composed of a sugar, a phosphate group, and a nitrogen base.

DNA consists of two strands of nucleotides joined by hydrogen bonds. This makes DNA appear in a double helical structure.

Long strands of DNA are contained in chromosomes inside the nucleus of a cell. Long strands of DNA in the nucleus are rolled into neat little bundles. Hence the statement; ''short strands of DNA are contained in chromosomes inside the nucleus of a cell'' is false.
