Explanation:
Because we people select cows for breeding for their traits of big muscles and producing lots of milk so us humans artificialy seselct these healthy cows for their traits
The correct answer is option A farmer breeds cows, developing larger, more muscled calves.
What are artificial and natural selection?Artificial selection is a measure taken by humans to identify desirable traits of plants and animals and to improve and maintain those traits in future generations.
Natural selection is natural selection, and artificial selection is human selection. The main difference between natural selection and artificial selection is that natural selection produces a large amount of biodiversity, whereas artificial selection produces the following types of organisms. B. Improved crops and livestock.

is it currently possible to take a core sample?
Answer is YES your welcome
Explanation:
Core samples are most often taken with their long axis oriented roughly parallel to the axis of a borehole, or parallel to the gravity field for the gravity-driven tools. However it is also possible to take core samples from the wall of an existing borehole.

According to the host, which of these is true of the reaction between ammonia and hydrochloric acid?
A.
It is considered an acid-base reaction because there is proton donation and acceptance.
B.
It is not considered an acid-base reaction because there is no hydroxide present in the base.
C.
It is not considered an acid-base reaction even though there is proton donation and acceptance.
Answer:
A.
Explanation:
In water, the reaction between ammonia (NH3) and Hydrochloric Acid (HCl) is an example of acid-base chemistry. By its chemical nature, the nitrogen in ammonia prefers to be attached to four hydrogens rather than the three it has, so it receives them from the hydrogen from HCl

Answer: It supports that the leftover radiation (neat) is spread uniformly (same) throughout the universe
Explanation:
The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background", or CMB.
what are the effects of mutations
Explanation:
When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.

theory that states all living things are made of cells, that they are the basic unit of structure and
function, and new cells are produced from exisiting cells
Answer:
unified cell theory
Explanation:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.

A fish in a pond has longer protective spines than any other fish of its species. The spines keep the fish safe from predators. The fish has many offspring, which also have long spines. Which statement BEST describes what happened? A A mutation caused a beneficial change in the fish. B A mutation caused a harmful change in the fish. C Shorter spines caused a genetic change in the fish. D Longer spines caused a genetic change in the fish.
Answer:
D
Explanation:
It is the longer spines that will help to protect the fish from predators. Longer spines caused a genetic change in the fish. The correct answer is option D.
What is the beneficial mutation in the mechanism ?It is the formation of the spines in the mechanism that is favorable as it is protecting the fish from prey so that they don't get attacked.
The many stickleback's populations went into the disparate with the parallel evolutionary's changes and among them the partial or can be complete loss of the pelvic spines. These spines do thought for protection of the fish from devouring by predators.
Initially, the stickleback's population in lake consisted mainly of fish with the pelvic spines but with over 15,000 years population changed to the fish without the pelvic spines. Studies having the living stickleback populations shows that the pelvic spines are an impressive defense against the larger predatory fish such as trout.

How do the hypotheses of ""phyletic gradualism"" and ""punctuated balance"" explain the process of lineage diversification?
Answer and Explanation:
Phyletic gradualism and punctuated balance are speciation theory. They are effective models for understanding macroevolution. Both define the rates of speciation. The phyletic gradualism model theorizes that most speciation is gradual, slow, and uniform, such as a black and yellow butterfly. When a butterfly is born, its color is yellow and orange, making it hard to see. The black and yellow butterflies become extinct over a long period, while yellow and orange butterflies can survive due to less visibility to predators. Punctuated balance suggests that once a species seems in the fossil record, the population will become steady and indicate little evolutionary modification, such as a species of birds live in stasis for numerous years. Suddenly bacteria affect their prime tree of shielding to die. The birds must adopt the changes. Some birds survive, and the remaining birds die. Until the others die out, more birds are born. Then the species again returns to a stasis state. The Gradualism model shows evolution as a slow, steady process in which organisms develop and change slowly over time, while punctuated balance models show evolution as a long period of evolutionary change. Due to the mechanisms of evolution in a time frame, both models describe successive evolutionary alterations.

Quantitative data is data in the form of numbers
Answer: The first option
Explanation: Quantitative data means data that is able to be measured or counted. The first option has 740, which can be counted. The second option is wrong because saying a lake is large is an opinion, meaning it isn't measured. The third option is also an opinion. The last option is also wrong since characteristics such as features or the appearance of something is not quantitative, instead they are qualitative features.
Quantitative data requires something to be measure or counted
Qualitative data requires observations, such as color or appearance

Agar is typically used in a final concentration of 1-2% for solidifying culture media. Smaller quantities (0.05-0.5%) are used in media for motility studies (0.5% w/v) and for growth of anaerobes (0.1%) and microaerophiles.
4. If a mutation blocked the function of the signal recognition particle, making it unable to bind signal sequence, what would result
Answer:
All proteins would be translated in the cytoplasm
Explanation:
The signal recognition particle (SRP) is a cytoplasmic RNA-protein (ribonucleoprotein) complex whose primary role is to target signal peptide‐bearing proteins to the plasma membrane in prokaryotes and to the endoplasmic reticulum in eukaryotes. In eukaryotic organisms, SRP binds to the signal sequence of the protein when the growing polypeptide chain emerges from the ribosome in the cytoplasm. This binding is key because it results in a slowing of translation, a mechanism known as elongation arrest. Therefore, without a functional SRP, elongation arrest would not occur and proteins would be translated on free ribosomes in the cytoplasm.

why is fertilizer essential
Answer:
Fertilizer is essential in agricultural practice because it adds the needed nutrients to the soil.
Explanation:
Given that each successful cultivation of crops leads to the removal of nutrients in the soil. To retain the level of nutrients in the soil so the plants can germinate extremely well. There is a need to add fertilizers to the soil.
Therefore, fertilizers are essential because "it adds the needed nutrients to the soil." Thereby retaining and improving the harvest level of plant crops.
