Explain how living organisms gain and use mass through the process of photosynthesis

1 answer:

5 0

Answer: Using energy from sunlight, photosynthesizers manufacture food (carbohydrates) from air (carbon dioxide) and water, and dump the waste product (oxygen) back into the air. So they gain mass (energy) which is utilized in many ways (e.g., food storage, procreation, structural support, protection, and much more).

Carbohydrates function in the diet to do which of the following

ad-work [718]

Answer:

carbohydrate like glucose, fructose, sucrose

they are either ketones or aldehyde

they can be of single. unit or made up of multiple units

carbohydrates are also called sugars because some are sweet and in daily life used as seeetner

what they do in body is provide fuel to body to carry out processes, helps in formation of atp and atp is used as energy currency

body doesn't let sugar come out of blood into urine

if its coming in urine we call it glucosuria

u may have diabetes if urine has glucose and protiens

butalik [34]

Answer:

This question is incomplete, the complete part is: What is the independent variable in this experiment? A) The plant species B) The amount of water that each plant gets C) The amount of time D) The different types of light the plants were put under.

The answer is D

Explanation:

In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light. Hence, the INDEPENDENT VARIABLE is the DIFFERENT TYPES OF LIGHT THE PLANT WERE PUT UNDER.

mart [117]

Answer:

Acute Lymphoblastic Leukemia (ALL)

Explanation:

The 5 year old, male patient is most likely suffering from Acute Lymphoblastic Leukemia.

INTRODUCTION:

Acute Lymphoblastic Leukemia is also known as acute lymphocytic leukemia and acute lymphoid leukemia. It is the most common cancer of children.

This disease is marked by neoplasm composed by blast cells. Blast cells are immature B or T lymphocytes.

PATHOPHYSIOLOGY:

Blast cells are marked by scant cytoplasm, larger than usual nucleus, inconspicuous (small) nucleoli and delicate chromatin. These cells stain positive for Tdt marker ( terminal deoxynucleotidyl transferase). Tdt marker is absent in mature lymphocytes but present in immature lymphocytes and acute lymphoblastic leukemic cells. Majority of ALL cells stain positive for CALLA. CALLA stands for common acute lymphoblastic leukemia antigen. CALL is also known as CD 10 (cluster of differentiation 10).

The blast cells infiltrate the bone marrow and replace it. Since RBCs are produced by the bone marrow, pathological infiltration results in the decrease in the number of RBCs produced. This may manifest as anemia with decreased Hemoglobin concentration on complete blood count/ blood complete picture test. Platelet level will also be decreased due to bone marrow infiltration. Sometimes complete blood counts may reveal increased amounts of WBCs by counting immature blast cells as WBCs.

Decreased RBCs present as symptoms of anemia with patient complaining of fatigue and lethargy. Decreased platelet counts may result in bruising on skin as the ability to heal trivial wounds is decreased.

QUESTION:

Coming back to the question, there are many cues which point towards this diagnosis.

The age of the patient i.e. 5 years old implies us to consider pediatric diseases. ALL is the most common cancer occurring in children.

Lethargy warns us to consider anemia in the patient.

Bruising points towards decreased platelets in this patient. Low blood platelet count is called thrombocytopenia.

Hb 9.2 g/dL, Hct 27.8%, MCV 91 fL confirm anemia (Normal values in children; Hgb 11-13 g/dL, Hematocrit 34%, MCV 75-90 fL) and platelet count 101,000/µL establishes thrombocytopenia (normal platelet count is 150,000-450,000 per microliter). WBC count 12,128/µL is normal ( normal values in 4-7 years children 6,000-15,000 cells per microliter) in this patient.

Replacement of bone marrow by primitive cells with large nuclei, delicate chromatin; indistinct nucleoli with scanty cytoplasm is a typical feature of Acute Lymphoblastic Leukemia.

Positive staining for CALLA establishes acute lymphoblastic leukemia in this patient as this antigen is positive in ALL cells and this disease is also implied by the symptoms, history and laboratory tests of the patient.
