Answer:

systemic lupus erythematosus

Explanation:

Systemic lupus erythematosus (SLE or just lupus) is a chronic inflammatory disease of autoimmune origin, the symptoms of which may appear in various organs slowly and progressively (in months) or more rapidly (in weeks) and vary with phases of activity and remission. Because it is a disease of the immune system, which is responsible for producing antibodies and organizing inflammation mechanisms in all organs, when a person has SLE they may have different types symptoms and various body locations. Some symptoms are general such as fever, weight loss, loss of appetite, weakness and discouragement. Others, specific to each organ such as joint pain, skin blemishes, pleural inflammation, hypertension, and / or kidney problems.

The main cause of this disease is the imbalance in the production of antibodies that react with proteins in the body itself and cause inflammation in various organs such as the skin, mucous membranes, pleura and lungs, joints, kidneys, etc.). Thus, we understand that the type of symptom a person develops depends on the type of autoantibody the person has, and that as the development of each antibody relates to the genetic characteristics of each person, each person with lupus tends to have clinical manifestations. specific and very personal (symptoms).

Autoantibodies are antibodies directed to the body's own cells and tissues. Normally, the immune system differentiates the body's own proteins from foreign proteins, forming antibodies only against those identified as potentially dangerous.

A Paramecium has an internal sucrose concentration of 0.040 M, a glucose concentration of 0.035 M, and a fructose concentration
Nadusha1986 [10]

Answer:

<u>c. Sucrose and glucose</u>

Explanation:

The paramecium is a large, single-celled microbes, surrounded by a plasma membrane. Simple diffusion occurs in cells across plasma membranes, as a form of passive transport. In diffusion, solutes move from regions of high concentration to regions of low concentration across the plasma membrane.

Here, the internal environment has higher concentrations of sucrose and glucose, but lower concentrations of fructose, thus the solutes will move along their concentration gradient, to where the concentrations are lower. In order for the fructose molecules to move out of the cell, the molecules have to move against their concentration gradient - a process requiring energy known as active transport.

Monica [59]

Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. To determine this, he uses an isotope of oxygen called O-18. He labels the O-18 oxygen so he can follow its path through photosynthesis. Plant A is given carbon dioxide that contains the O-18 isotope. Plant B is given water that contains the O-18 isotope. When he examines the oxygen from both plants, only plant B produced O-18 oxygen. This indicates that the source of oxygen is water. The photosynthesis involves the transfer of electrons between the photosystem I and II. The water gets split into oxygen, hydrogen ions and electrons in the photosystem I. The electrons move to the photosystem II where the carbon fixation into sugars takes place. The plant A will have O-18 isotope in its synthesised sugar molecule, which gets stored inside it.

For this question, we will utilize a population of Martians that is in Hardy Weinberg Equilibrium. The dominant Martian phenotyp
Brrunno [24]

Answer:

d.0.48

Explanation:

When a population is in Hardy Weinberg equilibrium the <u>genotypic </u>frequencies are:

freq (AA) = p²

freq (Aa) = 2pq

freq (aa) = q²

<em>p</em> is the frequency of the dominant <em>A</em> allele and <em>q</em> is the frequency of the recessive <em>a</em> allele.

In this population of 100 individuals, 84 martians have the dominant phenotype and 16 have the recessive phenotype.

Therefore:

q²=16/100

q² = 0.16

q=√0.16

q = 0.4

And p+q=1, so:

p = 1 - q

p = 1-0.4

p = 0.6

The frequency of heterozygotes is:

freq (Aa) = 2pq = 2 × 0.4 × 0.6

freq (Aa) = 0.48

A bacterial genome is typically a single linear piece of DNA. multiple linear pieces of DNA. a linear RNA molecule. a single cir
Schach [20]

Answer:

The correct answer is Single Circular DNA Molecule.

Explanation:

A bacterial genome, which is the DNA that is found in bacteria collectively, is a double stranded circular DNA. So it has no start and end like double stranded helix DNA. The option D, which is "Single Circular DNA Molecule" is correct.

I hope this answer helps.
