Could a particular form of life survive on the Martian surface

NASA reignited our hopes of finding alien life when it announced the first direct evidence of liquid water on Mars. But before we start indulging in fantasies of space crabs and reptilian beings, we ought to remember that Mars is a frigid world with a thin atmosphere. And that raises an obvious question: What sorts of life forms could actually live there?

Any life on Mars today is almost certainly microbial, but beyond that, we can’t be sure of anything until we actually dig it up and study it. Still, we can make some educated guesses about the nature of Martian life, by taking a deep dive into some of the weirdest biology on planet

Myocardial infarction or MI is also known as heart attack. This happens when the blood flow decreases due to blockage in the arteries causing ischemia in the heart secondary to poor oxygen. The symptoms include chest pain that can radiate to the shoulder,back,arm jaw and neck. This is one of the assessment finding the nurse should monitor.

In humans, dimples (D) are dominant over no dimples (d). Curly hair (A) is dominant over

jeyben [28]

Answer:

1. ddaa

2. DdAa

3. One from each parent

4. False

5. 0.25

6. 0.25

7. 0.25

8. 0.5

Explanation:

The remaining part of the question is

1. What is Jane's genotype?

2. What is Paul’s genotype?

3. Where did Jane get her gene for curly hair? From her mother or father?

4. True or False: Jane's mother was heterozygous for curly hair?

5. What fraction of Paul and Jane's children should have curly hair and dimples?

6. What fraction of their children would have straight hair and no dimples?

7. What fraction should have dimples but not curly hair?

8. What is the probability of getting any offspring with dimples

Solution

1. Genotype of Jane's mother -ddaa

2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa

3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was Aa)

4. False. She was having straight hair

5. Offspring of Paul and Jane

DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)

4 out of 16 offspring will have curly hair and dimples = 0.25

6. ddaa, 4/16 = 0.25

7. Ddaa , 4/16 = 0.25

8. Ddaa, DdAa, 8/16 = 0.5

Erythrocytes, neurons, skeletal cells, and columnar cells are examples of _____ cells.

lesya [120]

<span>Erythrocytes, neurons, skeletal cells, and columnar cells are examples of: specialized cells. cell, in biology, the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes. There are many unicellular organisms, e.g., bacteria and protozoans , in which the single cell performs all life functions. In higher organisms, a division of labor has evolved in which groups of cells have differentiated into specialized tissues , which in turn are grouped into organs and organ systems. Cells can be separated into two major groups—prokaryotes, cells whose DNA is not segregated within a well-defined nucleus surrounded by a membranous nuclear envelope, and eukaryotes , those with a membrane-enveloped nucleus. The cyanobacteria and bacteria (kingdom Monera ) are prokaryotes. They are smaller in size and simpler in internal structure than eukaryotes and are believed to have evolved much earlier (see evolution ). All organisms other than cyanobacteria and bacteria consist of one or more eukaryotic cells. All cells share a number of common properties; they store information in genes made of DNA (see nucleic acid ); they use proteins as their main structural material; they synthesize proteins in the cell's ribosomes using the information encoded in the DNA and mobilized by means of RNA; they use adenosine triphosphate. as the means of transferring energy for the cell's internal processes; and they are enclosed by a cell membrane, composed of proteins and a double layer of lipid molecules, that controls the flow of materials into and out of the cell.</span>
