Answers
Answer:
a
Explanation:
ff x ff is the cross that will produce only offspring with smooth leaves.
What is cross?Cross means breeding of parents to produce offspring.
What is produce?Produce means to generate.
What is offspring?Offspring is the product of a cross.
f is the recessive allele of smooth leaves whereas F is the dominant allele of fuzzy leaves.

ecosystem stability?
A. High herbivore emigration from a grassland
B. Dune erosion by ocean water along a shoreline
C. An increase in the carnivore population in a desert
D. Two large populations competing for the same food source
Answers
The phrase dune erosion by ocean water along a shoreline best describes a density-independent limiting factor that can affect ecosystem stability (Option B).
What is a density-independent limiting factor?A density-independent limiting factor can be defined as any factor in a given ecosystem that may alter the homeostasis of the population that lives in a given geographic area.
These factors (density-independent limiting factors) are generally abiotic factors such as hurricanes, extreme temperature conditions, the presence of contaminants in the air that hamper life in a given area, etc.
Conversely, density-dependent limiting factors are biotic factors such as competitive species that alter the development of another population.
Therefore, with this data, we can see that a density-independent limiting factor is any abiotic condition that may alter the life of a population in a give geographic area and thus alter the homeostasis of the whole ecosystem.

Explanation:
A researcher wants to examine the effect of fertilizer and the effect of sunlight on the yield of tomatoes. She bought 60 tomato plants at local garden store. She randomly assigned 30 tomato plants to be planted on the sunny side of the hill and 30 to be planted on the shady side. The 30 plants which are planted on the shady side are randomly assigned to one of three groups. The first group are grown with no fertilizer, the second group with a small amount of fertilizer, and the third group with a large amount of fertilizer. The 30 plants which are planted on the sunny side are likewise randomly assigned to one of three group. The first group are grown with no fertilizer, the second group with a small amount of fertilizer and the third group with a large amount of fertilizer. All tomato plants are planed at the same time and are all treated alike (in terms of how they are watered, weeded etc.). Each plant is grown to maturity. The total weight of tomatoes obtained from each plant is recorded. Identify the factor(s) and the number of levels for each. a) Sunny, shady (2 levels) b) No fertilizer, small amount of fertilizer, large amount of fertilizer (3 levels) c) No fertilizer and sunny, small amount of fertilizer and sunny, large amount of fertilizer and sunny, no fertilizer and shady, small amount of fertilizer and shady, large amount of fertilizer and shady (6 levels) d) Fertilizer (3 levels), location (2 levels) e) Fertilizer (3 levels), blocking variable – location (2 levels)

In this experiment, the fourth tomato plants—the group of tomatoes that do not get any fertilizers—serves as the control group.
Fertilizer is any substance, whether chemical or natural, applied to the soil with the intention of boosting productivity. Tomato groups behave as a reference group when fertilizer is added, whereas tomato groups that have no fertilizer added behave as a control group. The aforementioned description is true as a result. The group in which nothing is altered is known as the control group. To determine whether the changes you make in the experimental groups actually had an impact, use this as a foundation or baseline. In the absence of this, your experiment is worthless since there is no evidence that the adjustment you performed was the root cause of the result you observed.

d) Investigators look for all the people leaving the crime scene to see if they are possible suspects.
Answers
Answer:
C) Investigators say that the suspect must be of a certain minority because that is who usually commits the crime in their precinct.
Explanation:
Cultural bias is the action where by someone holds a bias about a particular group of people or ethnicity due to the negative information which he or she had been feed with while growing up.
For example, when someone believes that, all crimes committed in America is done by African American people is a typical example of cultural bias. In the scenario given above, for the investigator to believe that, the suspect to be a certain minority rather than having an open view that it could have been anyone shows cultural bias and profiling of the investigators.

In a multistep biochemical pathway, the first enzyme necessary for the synthesis of the amino acid tryptophan is inactivated with increasing levels of tryptophan and reactivated as tryptophan levels decline. This is an example of
- receptor mediated endocytosis.
- autolysis.
- irreversible damage.
- irreducible complexity.
- feedback inhibition.
Answers
Answer: Irreducible complexity
Explanation:
Irreducible complexity can be defined as characteristic of complex system it is impossible to reduce the complexity of the system by removal of any parts to maintain the functionality of the system. The given situation is an example of irreducible complexity. The increased levels of tryptophan will inactivate the synthesis process but it is again reactivated when the levels decreases this is suggestive of the fact that it is impossible to reduce the complexity of the system.

Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Answers
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.
