Daren has sickle-cell disease. Because of the disease, some of Daren's blood cells are long and thin instead of being disk-shaped. Daren's father also suffers from sickle-cell disease, but his mother and two sisters do not. This is an example how A. a person can choose which genes he or she will inherit. B. cells can be influenced by genetic factors. C. cells always repair damaged genes immediately. D. a person cannot survive if even one cell becomes damaged.

Answers

Answer 1

Answer:

Answer: B cells can be influenced by genetic factors

Explanation: Daren has sickle cell disease. Sickle cell disorder is a kind of disease that affects the hemoglobin in the red blood cells. Hemoglobin, is a molecule in red blood cells that delivers oxygen to cells throughout the body. People with Sickle cell disorder have hemoglobin molecules called hemoglobin S, which distort the shape of the red blood cells. A normal red blood cell has a disc shape but people with sickle cell like Daren have their red blood cells and distorted into a sickle, or crescent, shape

Many bacteria are able to pass small pieces of the hereditary information on their DNA from one bacterial cell to another. This can sometimes result in an increase in the number of drug-resistant bacteria. What name is given to the process by which one bacteria transfers DNA to another? A) sporolysis B) conjugation C) gametic transfer D) haploid translocation

Answers

Answer:

The process in which one bacteria transfers DNA to another is called conjugation.

Explanation:

Conjugation is the process of transferring genetic material from one bacteria to another through direct cell contact. In the process of conjugation one bacteria acts as donor and transfer the DNA to a recipient. There is a specific DNA sequence present in Donor's DNA called fertility factor (F factor). F factor helps in the formation of pillus which is the site of genetic material transfer.

What is sustainability? How does the concept of sustainability relate to green energy?

Answers

Sustainable energy is energy that is consumed at insignificant rates compared to its supply and with manageable collateral effects, especially environmental effects. Another common definition of sustainable energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their needs. The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture. Sustainability science is the study of sustainable development and environmental science.

Conceptually, one can define three generations of renewables technologies, reaching back more than 100 years .
First-generation technologies emerged from the industrial revolution at the end of the 19th century and include hydropower, biomass combustion and geothermal power and heat. Some of these technologies are still in widespread use.
Second-generation technologies include solar heating and cooling, wind power, modern forms of bioenergy and solar photovoltaics. These are now entering markets as a result of research, development and demonstration (RD&D) investments since the 1980s. The initial investment was prompted by energy security concerns linked to the oil crises (1973 and 1979) of the 1970s but the continuing appeal of these renewables is due, at least in part, to environmental benefits. Many of the technologies reflect significant advancements in materials.
Third-generation technologies are still under development and include advanced biomass gasification, biorefinery technologies, concentrating solar thermal power, hot dry rock geothermal energy and ocean energy. Advances in nanotechnology may also play a major role.

Answers

B. HEMOGLOBIN. In sickle cell anemia, the hemoglobin is mutated or abnormal and it gives the red blood cells a crescent shape. This abnormal hemoglobin is referred to as hemoglobin S.

A student pushes against a tree with a force of 10 newtons (N). The tree does not move. What is the amount of force exerted by the tree on the student?1) 0 N
2) 5 N
3) 10 N
4) 20 N

Answers

The amount of force exerted by the tree on the student is 10 N

Given that,

A student pushes against a tree with a force of 10 newtons (N). The tree does not move.

Based on this, we can say that

The amount of force should be same as each & every action should be equivalent & in the opposite reaction as the newton third law of motion.

Therefore we can conclude that The amount of force exerted by the tree on the student is 10 N

10 newtons (N). If the tree had less, it would be pushed. If it had more, it would push the kid (not possible).

Which of the following is not part of the nitrogen cycle? a conversion of atmospheric nitrogen into usable organic compounds by bacteria b breathing in nitrogen gas from the atmosphere c nitrogen fixation d conversion of nitrogen from decaying organisms into ammonia

Answers

The following is not part of the nitrogen cycle - bbreathing in nitrogen gas from the atmosphere.

The nitrogen cycle is one of the biogeochemical cycles which includes the conversion of nitrogen into multiple chemical forms as it transfers among the atmosphere, terrestrial, and marine ecosystems.

carried out through both biological and physical processes
Nitrogen is the major part of the air we breathe, but it is unreactive, therefore, not participate in respiration at all so, nitrogen breathe out again.
Nitrogen fixation: conversion of atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation, mainly fixed by bacteria.
Ammonification: The nitrogen present in the tissues of a dead organism is in the form of organic nitrogen, which decomposes the tissue and releases inorganic nitrogen back into the ecosystem.

Thus, The following is not part of the nitrogen cycle - bbreathing in nitrogen gas from the atmosphere.
