Cane toads are large, nonnative, poisonous toads in Australia. After cane
toads entered Australia, scientists observed that the average head size in a
population of toad-eating snakes was getting smaller. Snakes with smaller
heads are not able to eat the large cane toads. What type of situation is this?
O A. Disruptive selection
B. Species richness
C. Directional selection
D. Genetic variation
The answer you are looking for is C
Natural selection is a process by which the organisms adjust to the variation in the environmental conditions so they can endure and thrive in the altered conditions.
The correct answer is:
Option C. Directional selection
This can be explained as:
Directional selection is a negative form of natural selection in which the inhabitants of one species is favoured over another.The species with better trait characteristics will be favoured over the organism with less preferred attributes.The allele recurrence in directional assortment shifts over time.Therefore, toads with better traits (head size) are favoured over snakes with smaller mouth sizes.

With increasing maternal age, the chances of observing trisomies increase significantly. Increasing paternal age is associated with de novo point mutations. Why?
Answer:
Mother: higher risk of an improper chromosome division
Father: higher risk to suffer point mutations in sperm cells
Explanation:
A trisomy is an alteration in the chromosome number (i.e., an aneuploidy), and occurs when a cell receives three chromosomes instead of two. The risk of aneuploidies -including trisomies- increases with the mother's age due to the fact that older eggs have a higher chance of dividing unequally, thereby leading to an imbalanced number of chromosomes between daughter cells. Moreover, a point mutation is defined as a genetic modification where a single nucleotide is changed in the DNA sequence. It has been shown that point mutations in children are determined to a large extent by the father’s age, which are due to mutations in germline cells (i.e., sperm cells) that were passed to the progeny. A child born from a father who is 20 years old exhibits on average 40 point mutations, whereas a child born from a father who is 40 years old has typically twice the point mutations on its genome.
Based on calculations, students should have 10.4 grams of powder after conducting an experiment. The students get these results: 10.2 grams, 10.4 grams, 10.3 grams, 10.4 grams, and 10.5 grams.
Which words best describe this data?
accurate and precise
falsified and inaccurate
invalid and redundant
redundant and falsified
Answer:
accurate and precise
Explanation:
Given:
True value = 10.4 grams
Measured values = 10.2 grams, 10.4 grams, 10.3 grams, 10.4 grams, and 10.5 grams.
Solution:
To a very reasonable extent, the values measured given are accurate and precise.
Accuracy is the nearness of the measured value to the true value. We can see that the measured value would have a mean of 10.36grams which is very close to the true value on approximation.
Precision is the ability to repeat a given set of values from a measurement. The measured values are quite precise.

What do some scientists today believe causes more adaptations' competition or environmental changes?
Answer:
According to an April study, table corals (Acropora hyacinthus) can adapt to resist bleaching in warmer waters. On Ofu Island in American Samoa, A. hyacinthus lives in both hot and cool pools. In the lab, researchers tested corals from both environments to see how they reacted to increased heat.
Explanation:
i dont really know i tried
Some scientists today believe that adaptations are more caused or provoked by the fact of competition.
What is meant by Adaptation?Adaptation may be defined as the process that significantly involves the modification of internal and external attributes of organisms that makes them fit for survival and reproduction in the natural environment.
Competition is because of the fact that as the diversity of organisms increases, the resource limits remarkably enable the organisms to activate the mechanism of competition. Due to this, each and every species makes itself superior in order to make their survival in the natural environment.
Therefore, some scientists today believe that adaptations are more caused or provoked by the fact of competition.

B Enzymes make otherwise slow reactions proceed more quickly.
C Enzymes provide energy for endergonic reactions.
D. Enzymes are usually specific for the chemical reactions they catalyze.
The false statement about enzyme is - option C. Enzymes provide energy for endergonic reactions.
Enzymes are protein acts as biological catalysts. Enzymes increase the rate of reactions by lowering the activation energy.
Enzymes are made from amino acids. The chain of amino acids then folds into a unique shape.These are specific for the chemical reactionsEnzymes are biological catalysts that increase the rate of chemical reactions inside cells by lowering the activation energy therefore can not provide energy.Enzymes make slow reactions proceed more quickly.Thus, the false statement is - option C.

moves upward.
A metal rod would not be a good choice for roasting marshmallows because
metal transfers thermal energy.
Answer:
O As the air around the campfire is heated and becomes less dense, it rises and moves upward.
Explanation:
This is true because, the convection transfer needs the particle of elements to transport the heat from where it is in abundance to where it is in less abundance. Just like a water boiling becoming hot at the point closer to the fire than the top of the pot, so also will the air around campfire transfer heated air from the place closer to the campfire to upwards aware from the fire.
Convection is the flow of air around the campfire when it is heated and the decrease in density as it rises upward in the atmosphere. Thus, the correct option is C.
What is convection of heat?Convection is the transfer of heat from one place to the other due to the movement of fluids present in it. It is a distinct method of heat transfer in systems. The convective heat transfer involves combined processes of conduction and advection in a system and its surrounding. Convection is the dominant form of heat transfer in liquids and gases.
The thermal radiation in the fire is mostly in the form of infrared waves and visible light. However, the campfire heat transferred via convection shoots straight up in the sky and never reaches to the ground level.
Therefore, the correct option is C.

Indicate which the following statements are true.
a. During glycolysis, glucose molecules are hydrolysed to yield CO2 and H2O
b. The cleavage of fructose 1,6-bisphosphate by phosphofructokinase yields two molecules of glyceraldehyde 3-phosphate.
c. When subjected to anaerobic conditions, glycolysis in mammalian cells continues and causes a buildup of pyruvate in the cytosol.
d. In the mitochondrial matrix, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH.
e. Fatty acids can be transported into mitochondria and converted into acetyl-CoA, FADH2 and NADH
Answer:
The correct answer is: D
Explanation:
(a) This process does not occur during glycolysis, it occurs after glycolysis since pyruvate is generally accepted to be the last product of glycolysis
(b) Phosphofructokinase does not produce two molecules of glyceraldehyde 3-phosphate but rather produces of one molecule of glyceraldehyde 3-phosphate and dihydroxyacetone phosphate
(c) During anaerobic conditions in mammals, pyruvate is converted to lactate by the enzyme lactate dehydrogenase. It can actually cause the accumulation of lactic acid/lactate in the muscle which causes muscle fatigue but does not cause buildup of pyruvate in the cytosol.
(d) In the fate of pyruvate, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH in the mitochondrial matrix. The acetyl-coA produced thereof serves as a precursor for the citric acid cycle.
what role does energy play in changing particle motion?
Answer:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
