Answer and Explanation:
Nutrition enables the organisms to grow and reproduce. Plants require water, light, and essential nutrients to fulfill their biochemical needs. Plants obtain food in two ways. Autotrophic plants can prepare their food from water and carbon dioxide by photosynthesis in the presence of sunlight, such as green plants. Heterotrophic plants cannot prepare their food. They obtain nutrients from the host plant. Parasitic plants have no leaves and depend on their host for existence. A saprophyte plant obtains its food from dead matter. An insectivorous plant has left to digest and attract insects. Animals depend on other organisms to fulfill their nutritional needs. Animals are classified into three groups, such as herbivores, omnivores, and carnivores. Carnivores are meat eaters such as tigers and lions. Herbivores are plant eaters such as koalas, deer, and birds. Omnivores are both plants and animal eater such as chickens, humans, and bear. That why Deshawn’s experiment supports this statement is that all organisms need a proper environment to carry out essential life functions.
Answer:
Nutrition permits the organisms to develop and reproduce. Plants require water, light, and crucial vitamins to fulfill their biochemical needs. Plants acquire meals in two ways. Autotrophic plant life can put together their meals from water and carbon dioxide by means of photosynthesis in the presence of sunlight, such as inexperienced plants. Heterotrophic vegetation can't put together their food. They gain vitamins from the host plant. Parasitic flowers have no leaves and rely on their host for existence. A saprophyte plant obtains its meals from lifeless matter. An insectivorous plant has left to digest and entice insects. Animals rely on different organisms to fulfill their dietary needs. Animals are labeled into three groups, such as herbivores, omnivores, and carnivores. Carnivores are meat eaters such as tigers and lions. Herbivores are plant eaters such as koalas, deer, and birds. Omnivores are each flowers and animal eater such as chickens, humans, and bear. That why Deshawn’s test helps this assertion is that all organisms want a perfect surroundings to elevate out critical existence functions.
Explanation:
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

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.

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.

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
