Answer:
Acquired traits are due to changes in the life style, injury, loss of body parts, disuse of some body parts. These are the traits which occur in the somatic cells. Changes in the somatic cells are not passed on to the offspring belonging to next generation. Hence acquired traits cannot be passed on to next generation.

What is the most important reason to control the conditions of an experiment?
O to make the experiment easier to repeat
O to reduce the amount of data that must be recorded
O because this is necessary for graphing the data
O because this is necessary for the data to be valid
Answer:
The answer would be the last choice, "because this is necessary for the data to be valid."
Explanation:
This is because in an experiment, things must be controlled or monitored in most ways; otherwise, the result of the experiment will be different from what it was meant to be. An experiment should be as exact as possible. If this is not possible, results may be unreliable.

How does altitude affect climate patterns in a region? Areas at high elevations have cooler temperatures. Air continues to warm as it rises to a higher elevation. Tropical regions do not have many differences in altitude. High-altitude areas have less variation in seasonal temperatures.
Answer:
A. Areas at high elevations have cooler temperatures.
Explanation:
Areas with high altitude or elevations have cooler temperatures because air molecules are less in the air at high elevation that decreases the gas pressure leading to low temperature.
Earth's surface absorbs heat and diffuses it into the atmosphere that warms up the earth's surface. Layers of the atmosphere in higher-altitude areas diffuses less heat and maintain the low temperature.
Hence, the correct option is "A. Areas at high elevations have cooler temperatures."

Which of the following best represents a function of a lipid within an organism? O Lipids are components of cell membranes All the answer choices are correct O Lipids are parts of proteins O Lipids form a large part of the helical DNA structure
Answer:
The statement that best represents a function of lipids within an organism is that they are components of cell membranes.
Explanation:
Lipids are biomolecules formed by the binding of fatty acids, important for structure, compound synthesis and energy reserve.
In living beings, one of the most important functions of lipids is to be the main component of cell membranes.
Specifically, phospholipids associate to form a double layer, called lipid bilayer, capable of acting as a semi-permeable membrane, due to its non-polar or hydrophobic character. In this way, membrane lipids fulfill a structural and protective function of the cell and its contents.
Regarding the other options:
Proteins are made up of amino acids, not lipids. Lipids are not constituents of the DNA structure.Which of the following describes the relationship between photosynthesis and cellular respiration?
A.Only animals carry out cellular respiration, only plants carry out photosynthesis
B.Photosynthesis releases energy from glucose and cellular respiration stores energy as glucose
C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide.
D.Photosynthesis requires oxygen and cellular respiration releases oxygen
Answer:
C.C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide
Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide. Hence, option C is correct.
What is cellular respiration?The process through which organisms use oxygen to break down food molecules in order to get chemical energy for cellular processes is known as cellular respiration. The cells of animals, plants, and fungi, as well as those of algae and other protists, all engage in cellular respiration. It takes place in mitochondria and cytoplasm.
Cellular respiration serves the straightforward objective of giving cells the energy they require to function. Food would be completely useless if living beings couldn't obtain the energy they required from it.
Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen). During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilize. As byproducts, carbon dioxide and water are produced.

This type of system does not interact with the environment around it. It recycles all of the mass on its own.
A. No system
B. Open system
C. Isolated system
D. Closed system
Answer:
C. Isolated system
Explanation:
The question above is related to the the topic, "Thermodynamics."
Thermodynamics refers to how energy is being transferred among molecules. This study focuses on the "system" and the "surroundings/environment"
There are actually three types of systems (open, closed and isolated). When it comes to "isolated system," such system doesn't interact with the surroundings. This means that, it is incapable of exchanging energy or matter with its environment. This means that neither mass nor energy will be able to enter it; thus, it recycles all of the mass on its own.

D. r
r-strategist are species that have large offsprings, but spend no time in parental care. Sea turtles can be considered exaples of r-strategist species.
What are r and k strategists?Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.
r strategist species have a high growth rate per capita, and low competition capabilities. This is why they can colonize new environments. But they can not compete with new-established species. r species are often displaced by k species.These species are mostly small-sized organisms with short life cycles. They reach sexual maturity early and have numerous descendants spending no time or energy in parental care.
k strategist species have a low growth rate per capita, but they are big competitors with the capacity of displacing other species and monopolizing the available resources.These are big-sized species that live for a long time, reaching sexual maturity in the advanced stages of their lives. They do not have numerous progenies, but they spend time parenting.
r and k strategies are closely related to reproductive strategies, habitat selection, and dispersion ability.
Considering this difference, we can assume sea turtles are r strategist.
They lay several eggs and leave them on the beach. They spend no energy in parenting. Even though they are buried, eggs are still in danger of being attacked by predators.When little turtles emerge, they have to manage to go to to the sea by themselves, being exposed to other predators.The strategy is to spend more energy in laying several eggs to increase survival probabilities, and less energy in parenting.

Which statement is FALSE about spontaneous generation theory? Group of answer choices When microbes grew in Needham's flask of broth, he proposed it was an example of spontaneous generation occurring in microorganisms. Spontaneous generation is a theory that life forms can be generated from non-living objects Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies. Louis Pasteur's swan-neck flask experiment demonstrated that spontaneous generation does not occur.
Answer:
Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies.
Explanation:
As rightly stated in the options of this question, the theory of Spontaneous generation is a theory that life forms can be generated from non-living or inanimate objects. Several scientists including Needham, Redi, Pasteur contributed to this theory experimentally by either proving or disproving it. Their contribution are as follows:
- John Needham boiled a broth containing living matter but noticed cloudy appearance representing microbial growth. Hence, when microbes grew in Needham's flask of broth, he proposed it was an example of spontaneous generation occurring in microorganisms.
- Francesco Redi, on the contrary, disproved the theory by conducting an experiment using meat. Redi DISPROVED the theory by concluding that flies were responsible for appearance of maggots on the meat. Hence, the statement that "Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies" is FALSE.
- Loius Pasteur also disproved the theory of spontaneous generation by using swan-necked flasks. His swan-neck flask experiment demonstrated that spontaneous generation does not occur
