Answer:
Mainly because Evolution takes millions and millions of years to happen.
Explanation:
Evolutionary theory require earth to be very old because the process of evolution takes millions of year to happen.
What do you mean by evolution ?Evolution is the process through which a population of organisms evolves as new generations replace ancestors. Individual species do not evolve; rather, communities of organisms do.
Natural selection processes like as environmental change, predation, or human disturbance create evolutionary adaptations, and these processes must continue and grow widespread for the change to remain and accumulate. That happens less frequently and slowly than you may expect.
Scientists have determined that Earth is 4.54 billion years old, with a 50 million year error, by dating the rocks in its ever-changing crust as well as those in Earth's neighbors, including the moon and passing meteorites.
Therefore, the Earth needs to be very old for evolutionary theory to be true.

(C) rate=

(D) rate
др
St
Answer:
(A) rate=
Sp
Ss

Explanation:
The rate of chemical is a measure of the speed of a chemical reaction.
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
Reaction rate is usually expressed in terms of a change in concentration of the chosen reactant or product per unit of time.
During a reaction, the concentration of the reactant decreases exponentially with time while that of a product increases exponentially with time.
Reaction rate = [tex]\frac{change in concentration of a reactant/product}{Time taken}[/tex]

Which best describes the permeability of a membrane?
O A. The total thickness of the membrane
B. The flexibility of the membrane
C. The number of molecules in the membrane
D. The ability to allow materials to cross a membrane
Answer:
D
Explanation:
D. is correct because the membrane works like a security guard and only allows certain materails to cross the membrane. The definition of permeability is the state or quality that allows something to pass through.
Permeability is a standard of easy motion of liquid and gases through a membrane or material. They allow the transportation and exchange of gases in a cell.
The statement that best describes the permeability of a membrane is:
Option D. The ability to allow materials to cross a membrane.
This can be explained as:
Permeability is a physical property of membranes and substances that allows the other molecules to move through them.It acts as a barrier from substances entering and exiting the cell or membrane and maintains the balance in a system.Therefore, permeability is the allowance of materials across the membrane.

b) How does the thermal energy of solid water change as it melts?
Answer:
Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!

Based on the description of DNA, given in the Do Now, what could be the nucleotide composition of a DNA double helix? 90 points 20% adenine, 20% guanine, 30% thymine, 30% cytosine 60% adenine, 20% thymine, 10% guanine, 10% cytosine 20% adenine, 20% thymine, 30% guanine, 30% cytosine 60% adenine, 20% guanine, 10% thymine, 10% cytosine
Answer:
20% adenine, 20% thymine, 30% guanine, 30% cytosine
Explanation:
Edwin Chargaff stated in his rule that, in a DNA molecule, the amount of purine bases (Adenine and Guanine) should equate the amount of pyrimidine bases (Cytosine and Thymine). Mathematically, this means that;
A + G + C + T = 100%
Where;
% Adenine base = % Thymine base
% Guanine base = % Cytosine base
Hence, according to this question, the DNA molecule described will contain
20% adenine = 20% thymine,
30% guanine = 30% cytosine
20% A + 20% T + 30% G + 30% C = 100%

A scientific question is a well-sustained question about a given phenomenon of the real world which can be answered by experimental and/or observational procedures. A good scientific question must be testable and lead to falsifiable hypotheses. The dependent variable is the variable that is being measured in the experiment, (i.e. it is being affected by the experimental procedure). On the other hand, the independent variable is the variable that isn't changed by the other variables that are being measured in the experiment.

NOTE - ANSWER IN PHOTO
REAL NAME - SHRESTH DUBEY
Individual organisms making up a population may be evenly distributed, randomly distributed with no discernible distribution pattern or grouped together. These distribution patterns are called uniform, random, and clumped.
Distribution patterns (also known as species dispersion patterns) refer to the distribution of individuals within a population at any point in time.
Dispersion is the process of a group of living things expanding the area or range in which they live. Dispersion occurs when individual organisms move from the area that they occupied before, or where they were born, to new areas.
Uniform means the population is uniformly distributed, random means the population is randomly distributed, and clustered means the population is clustered.
The labeled diagram showing the population distribution patterns is given below.

O Growth and development
Homeostasis
Answer:
homeostatis
Explanation:
The answer should be homeostatis. Organisms can not do this.
Answer:
Ability to move
Explanation:
All organism species have the ability to reproduce, grow and develop, and maintain homeostasis (for example, sweating). Not all organisms can move, however. Cacti, for instance, are stiff and do not move on their own, yet are still alive.

How does evolution explain the similar legs in mammals and explain why the function differently?
Answer/Explanation:
These are examples of homologous structures. These are derived from common ancestors , however, they do not necessarily perform the same function. A good example is the vertebrate forelimbs like the ones shown here.
These limbs all have the same basic pattern of bones. They inherited this pattern from a common ancestor, but they now have different functions. This is an example of divergent evolution

Refer to the family pedigree shown here. In generation I, one parent is affected by the gene mutation and one parent isn't. In generation II, all three children are affected by the gene mutation. What can you conclude about this gene mutation?
Answer:
What can be concluded about this genetic mutation is that it is inherited as a dominant trait.
Explanation:
In the case that one of the parents has a mutation whose inheritance pattern is dominant —which is rare— all the descendants will have the same mutation, since this gene will necessarily be expressed.
A dominant allele is one whose presence produces the phenotypic expression of the characteristic it determines. When the mutation is dominant, it will always be expressed in the descendants.
Hungtinton's disease and achondroplasia are examples of mutations with an autosomal dominant inheritance pattern.
What are the parts of the compound light microscope
: The three basic, structural components of a compound microscope are the head, base and arm.
•Head/Body houses the optical parts in the upper part of the microscope.
•Base of the microscope supports the microscope and houses the illuminator.
•Arm connects to the base and supports the microscope head.
The head, base, and arm are the three fundamental structural elements of a compound microscope.
Thus, Head/Body houses the optical components in the microscope's upper section. The base of the microscope holds the illuminator and supports the microscope.
Arm supports the microscope head and is attached to the base. The development of the field of microbiology brought into focus the significance of the identification, seeing, observation, and comprehension of microbes, including their structural morphologies and mechanisms.
The study of tiny creatures and agents that can only be seen and investigated under a microscope falls under the purview of microbiology.
Thus, The head, base, and arm are the three fundamental structural elements of a compound microscope.
