A forest has many trees and bushes that produce nuts. This is a major food sources for many species, including a particular bird. Birds of this species have a variety of beak shapes ranging from long and pointy to short and hard beaks. The birds with short and hard beaks are able to eat the nuts better than the birds with long and pointy beaks. According to this scenario and the principles of natural selection what will happen to this bird population over time. Group of answer choices
Answer:
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection. After a while the birds will get old and their beaks will get weaker, eventually they will die, when there is a shortage of food they will start harming each other in order for it, that’s selection.

Which of the following tests does not involve mixing a solution with a reagent? Multiple Choice O lodine Biuret paper Benedict's or et? ided nt sence ide-re
The test that does not involve mixing a solution with a reagent is the Biuret paper test (Option B).
Biuret test is a simple and quick biochemical assay that uses a color change to detect the presence of peptide bonds in a protein or amino acid molecule. The biuret test is a quantitative laboratory test used to determine the presence of peptide bonds in proteins and other molecules. The test gets its name from the biuret molecule that is produced when the reagent in the test reacts with peptide bonds.
The principle of the Biuret test is based on the formation of a purple-colored complex, which is due to the reduction of Cu⁺² ions to Cu⁺ ions by the peptide bonds of protein in an alkaline environment. The amount of complex formed is directly proportional to the amount of protein in the sample.

1. Which of these is NOT a characteristic of a biome?
A Regions that have the same plant communities
B Regions that have the same animal communities
C Small habitat such as a tree stump that contains its own ecosystem
D Large areas of the Earth that have similar climates and organisms
Small habitat such as a tree stump that contains its own ecosystem is not a characteristic of biome.
What is a biome?A biome is a large geographic region on Earth that is characterized by a specific set of climatic and environmental conditions, as well as a distinctive community of plants and animals. Biomes are defined by their dominant vegetation, which is adapted to the specific climate and environmental factors of the region. There are several different types of biomes, including forests, grasslands, tundra, deserts, and aquatic biomes such as oceans and freshwater ecosystems. Biomes are important for maintaining biodiversity and ecological balance, and are also valuable for human use, providing resources such as timber, food, and water. The study of biomes is an important aspect of ecology, and helps us understand how living organisms interact with their environment.
Which of these is not a characteristic of a biome?c) Small habitat such as a tree stump that contains its own ecosystem. The other options are all characteristics of a biome. Biomes are large areas of the Earth that have similar climates and organisms, and are characterized by the same plant and animal communities. Biomes are typically defined by their predominant vegetation type and are classified based on factors such as temperature, precipitation, and soil type. Therefore, option C is the correct answer.

according to tinbergen, if you are examining a trait in order to determine how it contributes to the survival and reproduction of an organism, what are you studying?
According to Tinbergen, if you are examining a trait to determine how it contributes to the survival and reproduction of an organism, you are studying the trait's adaptive value or fitness.
Niko Tinbergen was a renowned ethologist who proposed four questions to understand behavior in animals, including the study of traits. One of these questions pertains to the adaptive value or fitness of a trait, which focuses on how the trait affects the survival and reproduction of an organism.
By examining the trait's contribution to an organism's ability to survive in its environment and successfully reproduce, researchers can gain insights into the evolutionary significance of the trait. This approach helps in understanding the selective pressures that have shaped the trait over time, as traits that enhance survival and reproduction are more likely to be favored by natural selection.

Which of the following is considered a abiotic 
A : algae bloom
B : fish life
C : animals waste
D : sediment deposition
Answer:
sediment deposition
Explanation:
Abiotic factors are the non-living pieces of the climate that can regularly affect living creatures. Abiotic factors incorporate water, daylight, oxygen, soil and temperature.
Brainliest?
Answer:
D: sediment deposition
Explanation:
An abiotic factor in an environment is a factor that is not, nor has ever been alive, and it didn't come from a living organism. The opposite of abiotic is biotic; a biotic factor is alive. So, sediment deposition would be abiotic because, unlike the other options, it was never alive and did not come from a lining thing.

How are the different parts of the plant reproductive system function to carry out sexual reproduction?The stamen is composed of anthers and filaments and is responsible for making the male gamete. The pistil is the female reproductive part of the flower and it is divided into three parts namely stigma, ovary, and style. It produces the female gamete. The primary function of the flower involves the production of male and female gametes and it carries out the process of sexual reproduction in plants.
The process of meiosis is used to produce the gametes. It occurs in the anther and ovary which are the reproductive parts of the plant. Fertilization takes place in the ovary in plants.
The pollens are produced in the anthers of the flower. The egg cells are produced by the ovules of the ovary.

porque los alimentos se oscurecen?(platanos, palta, manzana, papa, etc) respondan pls✋
Answer:
Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.
Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.
Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.
