How do you know if something is alive? Describe some of the characteristics of living things.

Answers

Answer 1

Answer:

We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:

Reproduction - to make more of the same organism

Sensitivity - the ability to detect and react to stimuli

Nutrition - eat and digest food.

Movement - the ability to change its position or location

Respire - to breathe / gas exchange

Excretion - get rid of toxic / materials in excess

All living things show the characteristics above.  

For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.

Answer 2

Answer:

To be alive organisms have to include all of the following:

- Made up of a cell or cells

- Has DNA

- Can reproduce

- Responds to the environment

- Grows and develops

- Exchanges energy

- Evolves

Explanation:

Prokaryotic and Eukaryotic cells are both alive because they contain all of the seven necessary characteristics listed above. Viruses are not alive because they do not contain all of the seven characteristics listed above.

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?

Answers

Answer:

In the clarification portion below, the definition of the topic is mentioned.

Explanation:

This shows that the distinctions between people living in a culture or geographical region are often based on ethnicity including ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair color, body potential for heat resistance, and menu variety. In something like a specific race or ethnic group, these social traits bring them alongside, and the young government associated with a particular race is often obligated to answer the custom practiced by individuals related to such a particular demographic. These are assumed that understand the connection to a specific community follow these rituals only to solve difficulties they have previously faced due to errors perpetrated by certain ancestors.

A certain species of lizard comes in three colors: cream, golden, and brown. All lizards are a single solid color (ie, none ever have spots or stripes) You carry out matings between these lizards, and collect the following data:

• Cream and brown lizards can be true-breeding, but golden lizards never breed true.
• Matings between cream and golden lizards always yield cream and golden offspring in a 1:1 ratio.
• Matings between brown and golden lizards always yields brown and golden offspring in a 1:1 ratio.
• Mating golden lizards with other golden lizards always yields brown lizards, golden lizards, and cream lizards in a ratio of 1:2:1, respectively.

Required:
Assign allele symbols to all alleles of the lizard color gene, and indicate which genotypes result in which phenotypes.

Answer:

Cream and brown lizards can be true-breeding, but golden lizards never breed true.

Explanation:

The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions.
1. State a reason why the virus has spread to the Americas and likely to spread to Europe.
2. Define the term microcephaly.
3. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals.

Answers

Answer:

1. It is a highly contagious disease transmitted from person to person and thereby it is expected that infected persons carried the virus to America  

2. Microcephaly is a serious birth defect where a baby’s head is much smaller than expected.

3. Occipital bone. CNS malformations: ventriculomegaly, parenchymal and periventricular calcifications and cortical migration anomalies

Explanation:

The Zika virus (Flaviviridae) causes a contagious disease and it is transmitted by Aedes mosquitoes, which are also the main vectors of the dengue virus. Microcephaly is a condition where the baby’s brain has not developed properly during pregnancy, and it has been shown that this birth defect is associated with the Zika virus. During 2015 in Brazil, the incidence of infants with microcephaly born from mothers that contracted this disease during pregnancy was higher, thereby suggesting an association between both conditions. Baby health problems associated with Zika infection include microcephaly (skull partially collapsed), joints with limited motion, etc.

A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.
