Which of these statements best explains how natural selection provides evidence to the scientific theory of evolution? (4 points)
It shows how organisms choose to adapt to changing Earth conditions.
It proves that natural selection always leads to greater complexity in organisms.
It shows how organisms with perfect traits can be created to suit the environment.
It proves that some organisms with specific adaptations survive better than others.
Answers
Answer:
It's either the 3rd or 4th one.
Explanation:
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
Organisms can’t choose. Nature choose it when talking about natural selection.
Nothing is support it about being more complex.
Not everything is perfect.

In pea plants the trait for tall height is dominant over the trait for dwarf height. Which letter should be used to represent the genotype for plant height?
D
F
L
T
Answers
Answer:
The correct answer is - T.
Explanation:
Normally, the representation of the trait in the genotype of inheritance pattern is the first letter of the dominant character of the particular trait. In this case, the trait of the height of the pea plant is tall and dwarf.
Tall plants are dominant over the dwarf plant, therefore, the letter T would be used to represent the genotype for the height of pea plant, the small letter of the particular letter would be used to represent the alternate allele of the trait.

Type of democracy where citizens elect leaders to represent them in government dictatorship representative democracy oligarchy anarchy
Answers
Answer:
representative democracy
Explanation:
Democracy can be defined as a government of the people, by the people and for the people.
There are two (2) main types of democracy and these include;
I. Representative democracy: it's also known as indirect democracy and can be defined as a form of government which typically involves the process of having the citizens of a particular country vote to elect representatives (political leaders) to enact laws, create policies and make decisions on their behalf.
Hence, representative democracy is a type of democracy where citizens elect leaders to represent them in government.
II. Direct democracy: it can be defined as a process which typically involves the candidates voting for their preferred choice. Thus, their choices are reflected directly on the subject matter.
Generally, the type of government in which legislators such as senators or house of representative members are found is known as a democracy and they are saddled with the responsibility of enacting or making laws.

In Mendel's first set of experiments, the two forms of a trait always showed up in the ______ generation
Answers
Answer:
Mendel began his studies by growing plants that were true-breeding for a particular trait. ... In his first experiment, Mendel cross-pollinated two true-breeding plants of contrasting traits, such as purple and white flowered plants. The true-breeding parent plants are referred to as the P generation (parental generation).
Explanation:
Hope this helps a little. Pls mark brainliest.
In Mendel's first set of experiments, the two forms of a trait always showed up in the Parental generation or P generation.
What is parental generation?The parental generation is defined as the first set of parents crossed, where the genotypes of the parents will be used as the basis for predicting the genotypes of their offspring (the [tex]F_1[/tex]generation). The P generation is the beginning of Mendel's work on inheritance, or the acquisition of genetic traits by transmission from parents to offspring.
Mendel collected the seeds which is produced by the P plants that resulted from each cross and grew them, while their offspring were called the[tex]F_1,[/tex] or the first filial generation.
Thus, in Mendel's first set of experiments, the two forms of a trait always showed up in the Parental generation or P generation.

If the AG of a reaction was -31.45 kJoules, you would know that:
A. the products have more free energy than the reactants.
B. the reaction requires an energy input of 31.45 kJoules to proceed.
C. the reaction most likely leads to development of a more ordered system
D. the reaction is spontaneous
Answers
Answer:
The correct answer is - option D. the reaction is spontaneous. (considering it as delta G or ΔG)
Explanation:
If a chemical reaction has a negative ∆G it means the reactants have more free energy than the products due to the fact that they give off some of their free energy during the reaction.
Such reactions release free energy and therefore called exergonic reactions. These reactions are also known as spontaneous reactions as they do not require energy to take place.
Thus, the correct answer is - option D.

Look online and find out what each muscle group does and what at least 5 muscles do and list that information.
Flexor Group-
Peroneal Group-
Hamstring Group-
Gluteal Group-
Quadricep Group-
Extensor Group-
Sartorius Group-
Adductor Group-
Answers
Answer:
Flexor Group- group of five muscles mainly in charge of movements of forearm, hand and fingers.
Peroneal Group- these muscles play a role in the movements of the ankle joint and support of the foot.
Hamstring Group- The hamstrings are a group of muscles and their tendons at the rear of the upper leg. They include the biceps femoris, semitendinosus, and semimembranosus. The hamstrings flex the knee joint and extend the thigh to the back side of the body.
Gluteal Group- The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur.
Quadricep Group- The Latin translation of 'quadriceps' is 'four headed,' as the group contains four separate muscles: the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris. Each of the vastus muscles originates on the femur bone and attaches to the patella, or kneecap.
Extensor Group- The superficial extensors of the forearm are a group of six muscles situated in the superficial posterior compartment of the forearm. These muscles include the brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor carpi ulnaris and extensor digiti minimi.
Sartorius Group- couldnt find anything
Adductor Group- The adductors are a group of muscles, as the name suggests, that primarily function to adduct the femur at the hip joint. Although they are all located somewhere along the medial side of the thigh, they originate in different places at the front of the pelvis.

Which characteristic do all protists have?
They all make or consume food.
They all survive in any environment.
They are all unicellular.
They all have flagella.
Answers
Answer: They all survive in any environment.
Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.
I'll explain why the others aren't correct.
Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.
Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.
Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.
Let me know if you have any questions.
