A process that is used to create energy when oxygen is available to the body.
A process that is used to create energy when oxygen is not available to the body.

Answers

Answer:

a high-energy molecule that is used by every cell in the body as an energy carrier.

Answer:

A high energy molecule that is used by every cell in the body as an energy carrier.

Explanation:

Adenosine triphosphate, also known as the "energy currency" of the cell is an organic molecule that readily supplies energy to the cells to carry out metabolic and catabolic functions. This molecule consists of a nitrogenous base known as adenine, ribose sugar, and three phosphate molecules. The hydrolysis of ATP provides energy for muscle contraction, nerve impulses, signaling for hereditary materials like DNA and RNA, as well as phosphorylation.

DDT is an insecticide that accumulates in the fatty tissues of animals whose concentration increases with each link of the food chain. Which group of organisms is most likely to accumulate the highest concentration of DDT?

Answers

The question is incomplete, the complete question is shown in the image attached

Answer:

D

Explanation:

Pollutants tend to an increase in concentration in the fatty tissues of animals compared to the concentration of the same pollutant in the environment.

Also, tend to increase in the fatty tissues of organisms at each trophic level.

Hence, as a result of this, the highest concentration of the insecticide is accumulated by the organisms at the highest level of the food chain. So, the tertiary consumers accumulate the highest concentration of the insecticide.

Answers

Answer:

Due to lack of nutrients in the soil.

Explanation:

Within a few years the forest was dying because there is no nutrient is present in the soil which can trigger the growth and development of the sol. The fallen parts of trees such as branches, tree and leaves etc are decomposed by decomposers such as bacteria and fungi which turn the fallen materials into nitrogenous materials which can be used by the plant for its growth and development.

The most likely explanation here is that mitochondria was once a prokaryotic organism. The correct option is A.

What is mitochondria?

Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).

The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).

Mitochondria are special compartments (organelles) in our cells best known for their role as powerhouses, converting food molecules into ATP, a molecular fuel for the rest of the cell.

Mitochondria and chloroplasts most likely evolved from engulfed prokaryotes that were once self-contained organisms.

At certain point, an aerobic prokaryote was engulfed by a eukaryotic cell, which then formed an endosymbiotic relationship with the host eukaryote, eventually developing into a mitochondrion.

Thus, the correct option is A.

Explanation:

Determine the new concentration, in mg/mL, of the starch solution you diluted in the Erlenmeyer flask. Recall from the Procedures that there are 20 mg/mL of starch in the 2% solution. Use that to determine the milligrams of starch in the diluted starch solution. Then, divide the milligrams of starch by the total volume of the solution, which includes the water plus the starch solution. Record your results for use in future questions.
a. 2 mg/mL
b. 0.05 mg/mL
c. 0.2 mg/mL
d. 10 mg/mL

Answers

Answer:

0.05 mg/mL  ( B )

Explanation:

Given data:

20 mg/ml starch

2% solution = 2g of solute is in 100g of solvent

Determine the new concentration in mg/ml

Dilution equation = C1V1 = C2V2

new concentration ; applying the dilution factor

dilution factor = 1 : 400 ; ( 2 /400 )g = 0.005 g of solute is present in every  100 mL

∴ new concentration = 0.00005 g / 1 mL * ( 1000 mg / 1g ) = 0.05 mg/mL

Chris is studying oxidation and reduction reactions. Which of the following could she use as an example of an oxidation reaction?

Answers

Answer:

This question lacks options, the options are as follows:

A. formation of ATP from glucose during respiration

B. formation of carbohydrates from carbon dioxide during photosynthesis

C. formation of oxygen from water molecules during photosynthesis

The answer is A. formation of ATP from glucose during respiration

Explanation:

Oxidation reaction is a type of reaction that involves the loss of electrons (e-) by a compound or molecule. The compound/molecule that loses the electron is said to be OXIDIZED.

According to this question, Chris is studying oxidation and reduction reactions (redox). An example of oxidation reaction she could use is FORMATION OF ATP FROM GLUCOSE DURING RESPIRATION. Glucose (C6H12O6) undergoes series of oxidation reactions in glycolysis, Krebs cycle and ETC, as it loses electrons to eventually produce energy (ATP).

Her eyes are wide-set and slightly slanted. Her nose is short and flat, and she keeps her mouth slightly open. There is a straight crease across her palm, and her fifth digit is unusually short. The doctor tells her parents she has an inherited disorder. If you were the doctor what would you diagnosis Kate with? Discuss the etiology of Kate’s disorder? What is the biggest risk factor for this disorder? How can or will this disorder affect Kate? What test could have been completed to diagnosis this disorder before Kate’s birth?

Answers

Answer:

- These morphological features belong to Down syndrome.

- Diagnosis: Down syndrome (Trisomy Extra chromosome 21).

- Etiology: the presence of three copies of the autosomal chromosome 21 instead of two copies in body (somatic) cells.

- Most important health problem: Down syndrome increases the risk of developing Alzheimer's disease (other health problems include heart congenital defects, vision problems, hearing loss, hypothyroidism)

- Diagnostic test: Amniocentesis

Explanation:

Down syndrome (DS) is the most frequent chromosomal abnormality which is generally caused by the presence of an extra copy of autosomal chromosome 21, thereby it is an autosomal trisomy (trisomy 21). DS is often associated with intellectual disability and increased risk of developing Alzheimer's, as well as health problems including, among others, heart congenital defects, vision problems, hypothyroidism, blood disorders, hypotonia, endocrine problems, dental problems, seizures, etc. Amniocentesis is the most common invasive prenatal diagnostic procedure which is used to identify chromosomal abnormalities such as trisomy 21 (Down syndrome). Amniocentesis is done between 15 weeks and 20 weeks of pregnancy.
