Which of the following statements is true? Groundwater is the largest available source of freshwater. Most of Earth's water is found in lakes, rivers, and streams. Glaciers are made from frozen ocean water, so they are sources of saltwater. Most freshwater is used for public drinking and mining.

Answer: Groundwater is the largest available source of freshwater.

Ground water is a water reservoir. It accumulates in the saturated zone of the geosphere. The water accumulates when water from sources like river, lakes, ponds, rainfall, snow melt, and agricultural irrigation gets seep underground by the pores of soil and rocks. It is a largest source of freshwater, as it remains unexposed to the contamination.

Every single cell works like a small factory. e. Cells follow a genetic DNA blueprint to construct an organism. f. Cells are composed of different parts called organelles

Answer: All the statements that are provided here are true when a cell is taken into consideration.

Explanation: The cells are known to be the basic structure and functional unit of the body. They have their unique functions based on the different organs in which they are located.

There are some recognizable similarities like structure for the cells. The cells need energy for working and it acts as a small factory. The replication of DNA acts as a blueprint to construct new cells to form an organism.

Every cell of the body function with the help of some small organelles like Golgi apparatus, mitochondria et cetera.

Jerimiah is studying Wave A and Wave B. Wave A is traveling at 3 hertz, and Wave B is traveling at 1.2 hertz. What can be predicted about the waves if they were to crash into each other? Refraction would occur. Interference would occur. The resulting wave would travel at 4.2 hertz. The crest of Wave A would overlap the trough of Wave B.

Answer:

Correct answer is C

c. The resulting wave would travel at 4.2 hertz.

Explanation:

In this case constructive interference will occur and it will sum up or add both waves together. So that the resulting wave will travel at speed of 4.2 hertz. So, the correct option is C.

Karyotypes can be studied to determine an organism’s chromosomal makeup and to detect genetic defects. Patau syndrome occurs when an individual has an extra copy of chromosome 13, giving them three copies. Symptoms of Patau syndrome include extra digits, seizures, and cleft palate. Which word would geneticists use to describe the cause of Patau syndrome?

The answer is trisomy 13.


Trisomy 13 is a condition in which an extra copy of chromosome 13 is present. Instead of two chromosomes 13 in a cell, there are three chromosomes. This is a consequence of a failure of chromosome 13 to separate during the gamete development. Thus, an egg cell or a sperm cell will have two instead of one chromosome 13 and after a cross with normal gamete cell, a zygote will have three chromosomes 13.

The population in South Africa is more prone to sickle cell anemia (genotype “ss”). People with genotype “ss” survive only up to 14-15 years of age. People with “SS” are prone to malaria because the parasite resides inside their RBCs. People with genotype "Ss" are resistant to malaria because the parasite cannot reside inside their RBCs, and they can live a normal life (without sickle cell anemia). What kind of evolutionary force must be operative in South Africa?

Indeed, there are several alleles, providing protection against malaria, including allele of sickle-cell anemia (hemoglobin S), alpha- and beta-thalassemia, hemoglobin C and hemoglobin E. There are visible signs of strong selection pressure. First, abundance alleles suggests that the selection of supports almost any shape adaptation to the disease. Secondly, the pressure is so strong that despite the fact that almost all of these adaptations is very costly to their media, they are still maintained by selection.

Answer:

Theory

Explanation:

Theory is the set of fundamental principles of an art or a science, which provides a synthesized opinion, is a general notion, which can be refuted and reformulated.

A theory is the speculative part of a science, as opposed to practice. It is a system consisting of observations, ideas and axioms or postulates, constituting in its entirety a set that tries to explain certain phenomena. The explanation formed by a theory can be questioned in the future with the advancement of technology and the discovery of new concepts.

Exploring the south american rainforest, a scientist discovers a mysterious organism and brings it back to the lab for further study. what cell characteristics should the scientist examine to tell whether the organism is an animal or plant? why?

Answer:

In the given case, the scientist should first look for a cell wall as only cells of the plants possess a cell wall. After that he or she should examine for chloroplasts as animal cells do not possess chloroplasts. And finally, he or she should look for the vacuole, that is, if the vacuole is of small size, then it is most probably be an animal cell, however, if it is large then it is most probably a plant cell.

A mountain lion population recently experienced a drop in population size. Which of the following would best describe the limiting factor that is involved?

Answer;

B.The deer population experienced a rapid decline due to a parasite.

Explanation;

-Limiting Factor is an environmental factor that tends to limit population size. Limiting factors may be density dependent or density independent. The density dependent factors are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent limiting factors such as; availability of food, predation, disease, and migration.

-Density independent factors can affect a population no matter what it's density is. For example: natural disasters, temperature, sunlight, human activities, physical characteristics and behaviors of organisms affect any and all populations regardless of their densities.

What is the main difference between aerobic respiration and anaerobic respiration? a. Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not. b. Aerobic respiration occurs during photosynthesis, but anaerobic respiration occurs during cellular respiration. c. Aerobic respiration produces ATP, but anaerobic respiration does not. d. Aerobic respiration occurs only in living organisms, but anaerobic respiration occurs in nonliving organisms.

Answer;

A. Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not.

Explanation;

-Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy.

-Anaerobic respiration occurs when oxygen is not present. It consists of two steps. The first step, like aerobic respiration, is glycolysis, that produces ATP from the reactant glucose. The second step, fermentation, creates lactic acid or ethanol, depending on the type of fermentation.

-Both aerobic and anaerobic respirations are types of cellular respiration. It is clear both use glycolysis to produce ATP. Both generate energy by breaking down glucose, produce byproducts and depend on chemical reactions that are localized in the cytosol.
