How does an organisms life begin?
Answer:
Living organisms undergo growth and development. Every living organism begins life as a single cell.
Answer:
The life of an animal organism, obviously, begins at conception. But human life begins only at the moment that the animal has a mind. In some, very fast, developers this can happen before the age of one year; in a large majority of cases this happens between two and three years of age.

11. In which of the following examples will water move into the cells of the large intestine from the outside environment by the process of osmosis?
Osmosis occurs in the large intestine to transfer water from the feces into the neighboring cells.
What is the process of osmosis?Water is transported across cell membranes through diffusion and osmosis. The body reabsorbs absorbable solutes and electrolytes from meals (namely salt, potassium, and chloride ions).
The total solute concentrations and the permeabilities of the solutes in relation to water define the effective osmolality of a biological fluid, the large intestine to transfer water from the feces into the neighboring cells.
Water molecules move by osmosis across the cell membrane from a lower solute concentration to a higher solute concentration.
Therefore, osmosis, a kind of diffusion, is how water enters and exits the cell's large intestine to transfer water from the feces.

Meat tenderizer contains an enzyme that interacts with meat. If meat is coated with tenderizer and then placed in a refrigerator for a short time, how would the enzyme be affected?
Answer:
The enzyme would be deactivated.
Explanation:
Enzymes are usually deactivated by low temperatures.
Enzymes are proteinous in nature, function by catalyzing biological reactions, and have a particular range of temperatures where they function optimally. Above these temperatures, the catalyzing attribute of enzymes gradually declines till they are denatured by high temperature and below the optimal temperature, their catalyzing attributes also decline. However, instead of being denatured by very low temperatures, they become deactivated instead.

a friend believes that studying the genetics of dead organisms offers little benefit to modern day humans do you agree with this statement to use information from the article to support your argument.
Studying the genetic ancestry of humans can help explain why some people have a higher or lower risk of certain diseases. Finding the genes related to certain diseases will help fuel new drugs and therapies. For example, the article explains that people with six copies of CLPS genes seem to have a lower risk of diabetes
Explanation:
According to me, the process of studying the genetics of dead organisms offers significant benefits to modern-day humans.
What is Genetics?Genetics may be defined as the branch of biology that deals with the study of heredity and variations that are remarkably controlled by genes.
The genetics of dead organisms reveals the process and methodology of past organisms. It illustrates how the differences in present organisms lead to the process of evolution.
It compares the physiology, psychology, genomic sequencing, alterations in the genetic arrangements, etc. It also allows us to understand new facts and changes that fascinate evolutionary questions.
Apart from this, modern technology makes the study of dead organisms more effective and significant with numerous benefits like recombinant DNA technology, DNA analysis, isolation, etc.
Therefore, the process of studying the genetics of dead organisms offers significant benefits to modern-day humans.

When listing the levels of organization in organisms from least complex to most complex, which level is just below organs in complexity? cell organism organ system tissue
Answer:
Tissue.
Explanation:
Cells work together to make tissues and tissues work together to make organs. I believe tissues are right under organs in terms of complexity.
The level of organization is defined by the simple to complex arrangement. The tissues are below the organs in the level of complexity. Thus, option d is correct.
What is the level of organization?The arrangement of the most simple to the complex structure in a hierarchical manner is called the level of organization. It makes the population and the community of the ecosystem.
The atom is the most simple level that aggregates to form a molecule that makes a cell. Cells with similar functions make the tissues. The tissues with various fucntions combine to form an organ.
An organ along with different organs makes an organ system. The various organ system with various roles and activities makes the organism. Many organisms make a population that results in a community, ecosystem, and biosphere.

If an object is having a constant positive acceleration, what can we assume about the forces on it?
Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. ... If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.
The force on the object is unbalanced.
Acceleration is the change in velocity per change in time of motion.
At constant velocity, the acceleration of an object will be zero.Increase in the change of velocity causes increase in acceleration in positive direction.A positive acceleration indicates increase in the motion of an object.According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
F = ma
If the net force on an object is balanced, the acceleration of the object will be zero because the object will move at velocityHowever, if the force on an object is unbalanced, the object will accelerate.
Thus, we can conclude that the force on the object is unbalanced.
