Answer:
A. the new DNA molecule has two newly-made strands
Which statement describes a step in DNA replication?
Explanation:
The double helix unwinds and each strand forms a template for a new strand. The paired bases release many types of proteins. The DNA is cut into pieces using polymerase enzymes.

Explain unsaturated, saturated, and trans fats.
Answer:
SATURATED FAT
Imagine a building made of solid bricks. This building of bricks is similar to the tightly packed bonds that make “saturated” fat. The bonds are often solid at room temperature like butter or the fat inside or around meat. Saturated fats are most often found in animal products such as beef, pork, and chicken. Leaner animal products, such as chicken breast or pork loin, often have less saturated fat. Foods that contain more saturated fat are usually solid at room temperature and are sometimes called “solid” fat.
UNSATURATED FAT
Now, imagine the links in a chain that bend, move, and flow. The chain links are similar to the loose bonds that make “unsaturated” fat fluid or liquid at room temperature like the oil on top of a salad dressing or in a can of tuna. Unsaturated fat typically comes from plant sources such as olives, nuts, or seeds – but unsaturated fat is also present in fish. Unsaturated fat are usually called oils. Unlike saturated fat, these oils contain mostly monounsaturated and polyunsaturated fat.
A few food products such as coconut oil, palm oils, or whole milk remain as liquids at room temperature but are high in saturated fat.
TRANS FAT
Trans fat can be made from vegetable oils through a process called hydrogenation**. Trans fat is naturally found in small amounts in some animal products such as meat, whole milk, and milk products. Check the food label to find out if trans fat is in your food choices. Trans fat can often be found in many cakes, cookies, crackers, icings, margarines, and microwave popcorn.

Invertebrates have a higher net production efficiency than mammals. Which statement most likely explains this observation? A. Invertebrates are more abundant than mammals in an ecosystem. B. Mammals maintain their body temperature; invertebrates don't. C. Most mammals are secondary consumers. Most invertebrates are primary consumers. D. Invertebrates have smaller bodies than mammals.
Answer:
C. Most mammals are secondary consumers. Most invertebrates are primary consumers.
Explanation:
Net production efficiency (NPE) refers to how efficient an organism at one trophic level is in utilizing and transferring energy to the next trophic level. Consumer organisms obtain energy (from biomass) when they feed on other organisms. They then use this energy for their metabolic activities and transfer the rest when eaten or fed on.
The net production efficiency decreases with increasing trophic level because higher organisms use more energy than lower ones. In this case, invertebrates use energy they obtained lesser or more efficiently than mammals, hence, making them have a HIGHER net production efficiency than mammals. Therefore, invertebrates are mostly primary consumers and utilize energy lesser than mammals which are mostly SECONDARY CONSUMERS.

using the chart above, what is the percent of Thymine found in the cow's DNA?
a. 42%
b. 28%
c. 31%
d 22%
Answer:
What percent of DNA is cytosine?
Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.

What is the end product of the light-independent reaction?
Explanation:
Oxygenic photosynthesis is composed of two stages: the light-dependent reactions and the light-independent reactions. The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.

What were the major contributions of the H.M.S. Challenger to the study of oceanography? How did its expedition contribute to future studies of the ocean?
Answer:
The H.M.S. Challenger embarked from Portsmouth, England on December 21, 1872 and changed the course of scientific history. Physicists, chemists, and biologists collaborated with expert navigators to map the sea. This interdisciplinary spirit has continued to the present day. During the 4 year journey, the voyages circumnavigated the globe, sounded the ocean bottom to a depth of 26,850 feet, found many new species, and provided collections for scores of biologists.
C. Wyville Thomson led the expedition but died of exhaustion from the journey, which ended on May 24, 1876. The Challenger had zig-zagged around the globe and had visited every continent, including Antarctica.
The reports of the Challenger expedition were supervised by Sir John Murray, whose biological conclusions were of great importance to the later development of marine biology. He concluded, for example, that the deep-sea fauna was not "ancient," in that it did not resemble the faunas found in ancient fossil deposits.
Explanation:
Answer:
The H.M.S. Challenger changed the course of scientific history. The expeditions circumnavigated the world, sounded the ocean floor to a depth of 26,850 feet. Itdiscovered numerous new species, and supplied collections for hundreds of researchers over their four-year adventure. The Challenger was a corvette, a military ship that went by sail but had auxiliary steam power to help steady the ship during sampling. The expedition was commanded by C. Wyville Thomson, who died of fatigue on May 24, 1876, at the end of the voyage. The Challenger has zig-zagged its way around the world, stopping at every continent except Antarctica. Sir John Murray oversaw the Challenger expedition's reports, and his biological results were crucial to the eventual development of marine biology. For example, he decided that the deep-sea fauna was not "old" since it did not reflect faunas found in ancient fossil beds.

What affect do enzymes have on chemical reactions?
Answer:
Increases reaction rate by lowring its activation energy.
Explanation:
i.e If the chemical reaction completes in 5 hours it means that reaction's activation energy is very high.This factor causes decrease in rate of reaction so to increase reaction rate and to decrease activation energy enzymes or catalyst are added so now reaction will be completed in half hour.This is the importance of enzymes/catalysts.Enzyme and catalyst cann't start reaction but they increase rate of reaction and decrease time to reach equillibrium.

Which part of the digestive canal is involved in: (i) absorption of food ________________. (ii) chewing of food ________________. (iii) killing of bacteria ________________. (iv) complete digestion of food ________________. (v) formation of faeces ________________.
Answer:
Absorption of food is Small intestine.
Chewing of food is Buccal cavity.
Killing of bacteria is Stomach.
Complete digestion of food is Small intestine.
Formation of faeces is large intestine.
Explanation:
Digestion is the process where larger molecules are broken into smaller pieces to release nutrients.
Digestion of food starts from the mouth especially carbohydrates. When it is consumed the buccal cavity is involved in chewing which break it into smaller pieces and the salivary gland release amylase to break it down. It then move to the small intestine where enzymes break food into smaller pieces. The stomach is responsible for killing bacteria because it is an acidic.region. when the food are broken down, the nutrients are then absorbed through small intestine and the undigested food form faeces in the large intestine.
