In which of the following scenarios will natural selection most likely occur?
a
Very little genetic variation is present in the species
b
No reproductive barriers present in the area were the species is located
c
A geographical area that has limited food to support the individuals living there
d
Ideal environmental conditions resulting in less competition between individuals
Please Hurry
Answer:
C
Explanation:
There is limited food so only the individuals who can get the food will survive.
Natural selection can be defined as the process of selection of organisms that are better adapted to their environments. It refers to the changing and adaptation in the organisms.
Natural selection is based on the concept of 'survival of the fittest'. The organism that is best adapted to its environment will be 'selected' by nature to survive and thus, pass forward its genes to the future generation.The scenario when there is no genetic variation present there will be no natural selection as there will be no 'fittest' organism. Moreover, the absence of reproductive barriers is bound to allow gene flow between two populations. Natural selection occurs when the conditions are not ideal and genetic variations are present.Thus, it will occur in a geographical area with limited food. Hence, the correct answer is option C.

Some lizard species contain females only, so there is no sexual reproduction. In these
populations, what would be the major source of variation for natural selection?
A. recombination.
B. independent assortment. C. segregation. D. mutation.
Answer:
D. Mutation
Explanation:
An advantage of asexual reproduction over sexual reproduction is that organisms reproduce asexually have greater genetic diversity
Answer:
False
Explanation:
Sexual reproduction produces organisms with more diversity because the offsprings are each different in their own way, unless they are identical twins, while asexual reproduction usually produces offspring that are exactly alike with like variation. The asexual offspring are usually identical to the parent with the exact DNA sequence.

(Q002) Review the vertebral column and individual vertebrae from Exercise 3 (p. 166 of your lab manual). What similarities and differences do you notice between the three major types of vertebrae? Why might these similarities exist? Why might these differences exist? Humans do not have tails, so we do not have caudal vertebrae (the vertebrae that make up the tail). However, many other primates do have these vertebrae. Based on what you know about the other kinds of vertebrae, what would you expect caudal vertebrae to look like? Compare your estimation to images of caudal vertebrae in your classroom, online, or in books. How accurate was your estimation?
Answer and Explanation:
1. The biggest similarity between the main types of vertebrae is the location where they are found since they are all established on the body's back, precisely on the midline of the back. The main differences, on the other hand, are related to the size and weight of each of them.
2. The similarities exist because all the vertebrae have to promote the support of the body, the back being the most appropriate place for them to establish themselves.
3. The differences are related to the function and type of support that each vertebrae promotes, the higher the level of systemization, the larger and thicker the vertebrae must be.
4. The caudal vertebrae should be similar to the vertebrae of the coccix, since a tail would be a representation of elongation of the coccix. We can reach this conclusion through the analysis of images that promote the visualization of this area of the body.

how are photosynthesis and cellular respiration related?
A. they are both performed by plants
B. they are both performed by animals
C. they both require energy from the sun
D. they both produce glucose molecules
Answer:
A
Explanation:
Photosynthesis occurs in the chloroplast. (Only in plant cells)
Cellular Respiration occurs in both plant AND animal cells because those two cells have mitochondria. (Mitochondria is where the cellular respiration process occurs.)
So they are both performed by plants.
Why leaves float on water
Answer:
because they are very light and they're density is very low
Explanation:
i think thats why
Answer:
Leaves float on water since they are too lightweight to break the surface tension of the water. Leaves also contain chloroplasts; which makes sugars using sunlight (a.k.a. photosynthesis). One of the by-products of this process is Oxygen. The oxygen sits in the middle of the leaf, called the Parenchyma. This gives the leaf a lower density than water; thus causing it to float.

Answer:
The International Date Line (IDL) is an imaginary line of demarcation on the surface of Earth that runs from the North Pole to the South Pole and demarcates the change of one calendar day to the next. It passes through the middle of the Pacific Ocean, roughly following the 180° line of longitude but deviating to pass around some territories and island groups.

In the diagram below, what part of the excretory system is labeled B?
A-
A. Kidney
OB. Ureter
OC. Urethra
OD. Bladder
B.
D
Option(B) Ureter is the correct option.
The ureter is a vital part of the urinary system in humans. It is a muscular tube that connects the kidneys to the urinary bladder. Each human has two ureters, one attached to each kidney, and they play a crucial role in the transportation of urine from the kidneys to the bladder.
The primary function of the ureter is to carry urine that is produced in the kidneys to the urinary bladder for storage before it is eliminated from the body through urination. The ureters accomplish this by using peristalsis, a wave-like muscular contraction, to propel urine along their length.
The ureters have a complex anatomical course. They originate from the renal pelvis, which is the funnel-shaped structure that collects urine from the kidneys. From there, they extend downward, crossing over the brim of the pelvis and passing behind the peritoneum, the membrane lining the abdominal cavity.
The efficient functioning of the ureters is essential for the proper elimination of waste products and maintenance of fluid balance in the body. Any obstruction or abnormality in the ureters can lead to conditions like kidney stones, urinary tract infections, or urinary reflux.
In summary, the ureters are muscular tubes that transport urine from the kidneys to the urinary bladder. They rely on peristaltic contractions to propel urine, and their structure and positioning help ensure unidirectional flow.

The diagram below illustrates a cellular process.
Cell membrane
Cytoplasm
Which of the following best explains the process illustrated in the above diagram?
A Passage of water molecules through a semi-permeable membrane to equalize concentration
B.
Transport of molecules across a membrane from a high to low concentration gradient by means of a carrier protein
Movement of molecules against a concentration gradient expending energy
D.
Separation of suspended particles from a fluid environment to a non-fluid environment through a porous membrane
Answer:
B. Transport of molecules across a membrane from a high to low concentration gradient by means of a carrier protein
Explanation:
According to this diagram showing the presence of certain molecules on one side of the membrane, making their way to the other side across the membrane. Due to the difference in concentration on either side of the membrane, a concentration gradient is formed.
Based on the diagram, the movement or transport of molecules is occurring from a region of high concentration to a region of low concentration. This means that it's a form of PASSIVE TRANSPORT, however, the molecules are being transported across via the aid of CARRIER PROTEINS as depicted in the image.
What are enzyme and activation energy?
Answer:
Enzymes are proteins that bind to a molecule, to modify it and lower the energy required to make it react. ( In other words , enzymes are biological catalysts.
Catalysts lower the activation energy for reactions.
In simple terms , The lower the activation energy for a reaction, the faster the rate. )
The activation energy is the energy needed to start a reaction.
Explanation:
Thus enzymes speed up reactions by lowering activation energy.
