Answers
Answer:
In about 30 days
Explanation:
Assume Xavier sights a full moon today, it'll take around 29.5 days to see the moon at that size again.
Analysing each of the given options, only option D answers the question because 29.5 days can be rightly said to be about 30 days.
Or better still, 29.5 days approximates to 30 days.
Which of the following is true regarding enzymes?
A one enzyme can work with any substrate
B they can be used extracellularly
C they are made of only protein
D they are used entirely in the reaction
Answers
Answer:
C .they are made of only protein
Enzymes can be used extracellularly. Therefore option B is correct.
Enzymes are biological catalysts that facilitate chemical reactions in living organisms.
While enzymes are highly specific in their action, option A is incorrect because each enzyme typically works with a specific substrate or group of related substrates.
Option C is also incorrect because enzymes can be composed of both protein and non-protein components, such as cofactors or coenzymes.
Finally, option D is incorrect because enzymes are not used up entirely in the reaction but rather can be reused multiple times, making them efficient catalysts.
Therefore option B they can be used extracellularly is correct.

Cell cycle regulators are the cell cycle only when they are tight bound to CDKS.

Which function allows animals to find mates?
movement
homeostasis
reproduction
feeding
Answers
Answer: MOVEMENT
Explanation:
Movement
Movement can be described as the change in the place of an object or animals, without the ability to move there is not a possibility of life on earth. Movement is essential for many animals that help them to find food, shelter, and mate for the reproduction and produce offspring by mating.
The function that allows animals to find mates is movement, which is present in the first option as movement is a unique characteristic that is only present in animals but not in plants.
What is the significance of the movement?In the animal kingdom, movement is required to find a mate, as the animal must move from one location to another to find a suitable mate, while it is absent in plants. Plants do not move, but pollinators assist in this process, whereas animals use movement to find food by walking on their legs or flying, and they also use movement to find mating partners.
Hence, the function that allows animals to find mates is movement, which is present in the first option as movement is a unique characteristic that is only present in animals but not in plants.

During a science lab the teacher provided Michael with a triple-beam balance, a ruler, and four cube-shaped metals. Based on Michael's calculations and the table below, the conclusion can be BEST made Substances can be identified by their density
what is density?
Density refers to the mass of a unit volume of a material substance. The formula for density is represented by d = M/V, where d is density, M is mass, and V is volume.
It is commonly shown as units of grams per cubic centimeter, it can also be expressed as kilograms per cubic meter .
Density can used to define how different materials interact when mixed together. For example Wood floats in water because it has a lower density, while an anchor sinks because the metal has a higher density.
Density can be applied in pipe design, shipbuilding, helium balloons, weight distribution in the aero plane, and the fact that ice floats on water.

How Clark Developed Seizures
The following list is not in the correct order. The first three events are numbered correctly. Drag and drop the
remaining events in the order that led to Clark's seizures.
picture above for the order.
Answers
Answer:
4. Low blood sodium concentration
5. Net movement of free water into the matrix
6. Increased matrix pressure
7. Abnormal neuron firing rate
8. Seizures
Explanation:
Seizures are defined as the common complication of drug intoxication.
As per the clinical observations for Clark , normal blood and matrix sodium concentration lose sodium ions due to diarrhea. As given too much water causes sodium levels to decrease. Due to lower sodium concentration, the free water move into the matrix and increased matrix pressure. This pressure causes the abnormal neuron firing rate to increase which causes seizures.
Hence, the correct order is:
4. Low blood sodium concentration
5. Net movement of free water into the matrix
6. Increased matrix pressure
7. Abnormal neuron firing rate
8. Seizures

Which of the following is NOT true about matter in the biosphere?
a) Matter is transferred in one direction through the biosphere. b) Biogeochemical cycles transform and reuse molecules. c) The total amount of matter decreases over time. d) Human activity does not affect the movement of matter
Answers
Answer:
c) The total amount of matter decreases over time.
Explanation:
The statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).
The biosphere refers to the total of all ecosystems of the Earth.The biosphere can be defined as a closed system in terms of matter because matter does not enter or exit.In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time.This energy is lost in the form of heat when it spreads from the Earth's surface and outward into space.In conclusion, the statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

Southern Florida has many tropical hardwood hammocks—forest habitats that are warm, wet, and populated with many broad-leaved evergreen trees. Why might a plant native to an ecosystem with a cooler climate do well if introduced to a tropical hardwood hammock? Group of answer choices The trees in the tropical hardwood hammock are better at competing for native resources than the introduced species are. The wet conditions in the tropical hardwood hammock disrupt the life cycle and limit reproduction of the introduced species. Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock. Pollinators and seed carriers that normally increase the population in the cooler climate are lacking in the tropical hardwood hammock.
Answers
Answer:
Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock.
Explanation:
The tropical hardwood hammocks are habitats that act as small ecosystems markedly different from the surrounding environment, and they may be seriously threatened by introduced plant species. In Florida, exotic plants have been introduced into the tropical hardwood hammock habitat, reaching to about 50% of the flora in some areas. The mature hammock of these habitats can generate a shade that maintains a temperature of several degrees cooler compared to their neighboring habitats, and thereby promoting invasion by exotic species.
