Jayden is taking a test. He has to write why scientists support the theory that life began near hydrothermal vents in the ocean. Which point should he include in his answer?
A.
Hydrothermal vents were closest to ocean surface, and therefore could receive oxygen.
B.
Oceans were dry and only had water near the hydrothermal vents in the earlier ages.
C.
Even today, all life forms are first born near hydrothermal vents and they later migrate to land.
D.
Fossils of archeabacteria, which are early common ancestors, were found near hydrothermal vents.

Answers

Answer:

The answer is; D

Archaebacteria are early life forms on earth. They utilized the process of chemosynthesis to make organic molecules from inorganic molecules and for energy. The word archae means ‘ancient’ life forms. These single-celled organisms evolved around sulfur-rich environments of the hydrothermal vents.

What part of the cell determines the type and order of the amino acids that make up a protein?

Answers

Answer:

The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. 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.

Circle the word that best completes the statement about cell theory.

6. The cell theory states that:

i. All organisms are made of organelles / cells.

ii. All existing cells are produced by other living / dead cells.

iii. The atom / cell is the most basic unit of life.

7. Cell theory is one of the great unifying theories of biology / chemistry

Answer:

6. The cell theory states that:

i. All organisms are made of cells.

ii. All existing cells are produced by other living cells.

iii. The cell is the most basic unit of life.

7. Cell theory is one of the great unifying theories of biology

Explanation:

Cell theory is one of the central theories of biology and is universally accepted. It states that all organisms are cellular - that is they are made of cells. It also states that all living things come from other living cells (not spontaneously, or from dead cells). The cell is the most basic unit of life, organisms can be unicellular, but no living thing is 'less' than that.

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.

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.
