A.
B.
C.
Answer:
A
Explanation:
What results would be expected with no spontaneous generation of life
The results that would be expected with no spontaneous generation of life is no growth of microorganisms on the food particles.
What is spontaneous generation of life?The spontaneous generation of life was a idea which was used to explain the growth of microorganisms on food long ago die to the inability to see these organisms then.
Louis Pasteur by means of experiments proved this idea to be wrong. Life can only come from pre-existing life.
Therefore, the results that would be expected with no spontaneous generation of life is no growth of microorganisms on the food particles.

All of these are steps in the lytic cycle of a temperate bacteriophage. Which happens second?
The second steps in the lytic cycle of a temperate bacteriophage is the entry.
What are the steps in the lytic cycle of a bacteriophage?The lytic cycle has several phases: Absorption is the phase in which the recognition and attachment of the virus to the cell occurs. Viruses are very specific to their host cells. The host is endowed with chemicals capable of allowing the virus to detect it and attach itself to the membrane.
So, the 4 stages of the lytic cycle is attachment, penetration, biosynthesis, maturation, and release.

According to the research, muscle fibers can produce contraction and are made of myofibrils.
What are the muscle fibers?They are the fibers that are located inside the muscle, which in turn are composed of sarcolemma, mitochondria, myofibrils, nucleus and sarcoplasmic reticulum.
The myofibrils are responsible for giving it the elastic characteristic and are made up of actin and myosin that fulfill the function of generating the contraction process.

Select the correct answer. while examining a specimen under the microscope, janet discovers a structure that has some genetic material that has rna but not dna. what is the specimen? a. virus b. plant c. fungi d. bacteria e. animal
Answer:
A. Virus
Explanation:
Viruses chose to store their data in RNA so that they can make changes as their hosts develop immunities.
The specimen is of virus. The correct option is A.
Thus, A virus is an infectious microorganism made up of a protein-coated segment of nucleic acid (either DNA or RNA).
A virus can't multiply by itself; it has to infect cells in order to utilise the host cell's components to make copies of itself. A virus frequently causes harm to the host organism by killing the host cell in the process.
Viruses can infect people. But in reality, viruses infect a wide variety of organisms. For example, there are viruses that infect fungi and viruses that infect bacteria.
Thus, The specimen is of virus. The correct option is A.

Q3. Why do we need to break big molecules into smaller molecules?
Answer:
In order for them to be quickly and easily absorbed.
________________________________________________
Short Answer:
Enzymes help break down large molecules for us since certain of their components are the only ones that are useful to us. In order to create proteins, lipids, and other components necessary for survival, the tiny molecules become soluble and are quickly taken into the circulation. Additionally, they could need to travel through some membranes, therefore when they are little, they can do so without difficulty.
________________________________________________
Long Answer:
The nutrients in food must pass the gut lining in order to exit the digestive system and enter our blood. This absorption occurs in the ileum and jejunum regions of the gut. In some regions, the gut lining is brimming with chemical systems that may latch onto the food's smaller molecules and "chaparone" them across the gut and into the liver. These "chaparone" molecules can hold small peptides and amino acids but not whole proteins. Greater floor fragments do not absorb. Without "chaparones," some of the stomach-digested products pass through the gut's pores, but they must be smaller than the pores. Only tiny pieces and certain fragments with complementary "chaparones" of the food we eat are molecular fragments that are absorbed. A number of gastrointestinal conditions are caused by an imbalance in the gut's capacity to absorb nutrients. One condition where iron is not effectively absorbed is Cooly's anemia. Iron deficiency affects Cooly's anemia patients, even if their stomachs digest food correctly and they have normal iron absorption. Catabolism is the process of dissolving big molecules into smaller ones. Catabolism releases energy by rupturing bonds. Anabolism creates new connections and needs energy to function. Catabolic reactions (destructive or biosynthetic process) breaks down large molecules and release energy
What is a spring tide? When and why does it occur?
Answer:
Spring tides happen just after every full and new moon, when the sun, moon and earth are in line. That's when lunar and solar tides line up and reinforce each other, making a bigger total tide.
A spring tide occurs when there's a new or full moon. Because it follows the moon's lunar cycle, a spring tide happens twice per month. With the moon and sun roughly aligned the tides of Earth are on average slightly larger than usual.

Alan lives in an area that has a huge park. Moreover, there is good quality of air and water in his region. What is the possible consequence of such conditions?
A.
premature deaths
B.
asthma
C.
cardiovascular diseases
D.
high life expectancy
Answer:
D. High Life Expectancy
Explanation:
Air pollution lowers life expectancy and causes tons of premature deaths in areas. The area that Alan lives in has good air quality which means that there is obviously going to be a increase in life expectancy. If water quality is bad in an area it can cause chronic illnesses (such as cancer), gastrointestinal illnesses, and even effect the nervous and reproductive systems in a bad way. So the fact there is good water quality in the region the area Alan lives in, he is pretty much guaranteed for higher life expectancy. Therefore the best answer is Option D.

Write a reflection outlining what this tells you about Canada’s population density. What other information does this tell you
Answer:
With the findings of the 2016 Census count on population and dwellings, Statistics Canada gives Canadians a first look at the most recent national statistical snapshot.
The census counts 35,151,728 persons who said they lived in Canada on May 10, 2016, and displays population growth patterns across the country.
The organization will provide the complete spectrum of census data during the following year, as Canadians commemorate 150 years since Confederation, in order to portray a truthful picture of Canadians' lives and communities.
In 1871, the first census following Confederation recorded 3.5 million people in Canada, while the population figure in 2016 was ten times higher. When Canadians celebrated the 100th anniversary of Confederation in 1967, that number had risen to 20.0 million people (1966 Census).
Canadians have been making their way west for many years. The four founding provinces of Ontario, Quebec, New Brunswick, and Nova Scotia housed the majority of Canadians in 1871, whereas Western Canada was lightly populated. Manitoba, Saskatchewan, Alberta, and British Columbia accounted for over a third of the population in 2016.:
