Answer:
Should be C
Explanation:
D is wrong because standing out should mean they are spotted more easily, which means they get hunted down more often/ prey spot them easier
B is kind of weird because larger population = more competition, and I remember owls work alone
A is suspicious because they are both tawny owls and I don't understand how less food they need to be significant
C sounds plausible because the gray feather can be a "stronger" gene or something

Explain how sexual and asexual reproduction both lead to better evolutionary fitness.
Answers
Answer:
Hope you get done. friend me back. and can I have brainliest
Explanation:
To get diversity in individuals, genetic differences are required, and different phenotypes must be expressed. Since sexual reproduction is more conducive to driving evolution than asexual reproduction, much more genetic diversity is available for natural selection to work on. Evolution can happen over time.
A scientist compares two samples of white powder. One powder was present at the beginning of an experiment. The other powder was present at the end. She wants to determine whether a chemical reaction has occurred. She finds that neither sample bubbles or dissolves in water. She measures the mass and volume of the solids. Sample one has a volume of 45 cm3 and a mass of 0.5 g. Sample two has a volume of 65 cm3 and a mass of 1.3 g. What should the scientist conclude?
A.
The samples have the same color, so no chemical reaction has occurred.
B.
The two samples do not react with water, so no chemical reaction has occurred.
C.
The densities of the samples are different, so a chemical reaction has occurred.

Why do you think it's important for scientists to study plate tectonics? Explain.
Answers
Studying plate tectonics is important because it helps explain Earth's surface features, predict natural disasters, investigate Earth's history, explore natural resources, and understand global climate patterns. It is a multidisciplinary field that provides valuable insights into the dynamic nature of our planet.
Scientists study plate tectonics for several important reasons. Firstly, understanding plate tectonics helps scientists explain the formation of different features on Earth's surface, such as mountains, valleys, and ocean basins. By studying the movement and interactions of Earth's tectonic plates, scientists can better understand the processes that shape our planet.
Secondly, studying plate tectonics is crucial for predicting and understanding natural disasters. Earthquakes, volcanic eruptions, and tsunamis are all related to tectonic activity. By analyzing plate boundaries and identifying areas prone to seismic activity, scientists can provide early warnings and help communities prepare for potential disasters.
Furthermore, studying plate tectonics is essential for investigating Earth's history. The movement of tectonic plates over millions of years has shaped the continents and influenced the evolution of life on our planet. By examining the distribution of fossils and rock formations, scientists can reconstruct past tectonic events and gain insights into Earth's geological history.
Additionally, understanding plate tectonics is crucial for exploring natural resources. Many valuable minerals and energy resources are formed as a result of tectonic processes. By studying plate boundaries and their associated geological features, scientists can identify potential locations for mining and resource extraction.
Lastly, studying plate tectonics contributes to our understanding of global climate patterns. The movement of tectonic plates affects ocean currents, weather patterns, and the distribution of landmasses. By analyzing these interactions, scientists can better predict and understand climate change.

DNA sequences can act as "tape measures of evolution." Some highly-conserved regions of the human genome (similar to comparable regions in other species) don't code for proteins. Why?
1. Such regions coded for proteins in genomes of distant human ancestors, but over time they became noncoding; however, conserving their sequence remained unchanged.
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
3. Such regions are the sites of DNA recombination. They should remain conservative to provide an accurate recombination process during cell division.
4. Such regions remain conservative because the mutation rate differs along the genome. In other words, such regions remain conservative accidentally.
Answers
Answer:
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
Explanation:
Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.

How would a cell wall aid a plant during a period of heavy or prolonged rainfall?
Answers
Answer:
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against stress
Explanation:
The cell wall aid a plant during a period of heavy or prolonged rainfall by providing structural support, prevents water damage, regulates water uptake and maintains turgor pressure.
What is a cell wall?Cell wall is the outermost covering of the cell above the plasma membrane, which plays an important role in helping the plant survive during periods of heavy rainfall and prolonged rainfall.
The ways in which it provides protection are:
Structural support- It provides necessary strength and rigidity to the plant, which helps it to stand upright and not collapse under the weight of water.Prevents water damage- It acts as a barrier by preventing water from entering the cells and causing damage to the plant internal structure.Regulates water uptake- It controls the flow of water into the plant, which helps regulate the water uptake and prevent the plant from taking in too much water.Maintains turgor pressure- It also helps to maintain turgor pressure.Hence, the cell wall provides significant support and protection for the plant during periods of heavy and prolonged rainfall.

Describe the relationship between the sickle cell phenotype and hemoglobin’s structure and function
Answers
Answer: Explanation:
Sickle hemoglobin differs from normal hemoglobin by a single amino acid: valine replaces glutamate at position 6 on the surface of the beta chain. Therefore the red blood cell bends differently giving it a sickle shape
Answer:
Explanation:
Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.
Signs and symptoms of sickle cell disease usually begin in early childhood. Characteristic features of this disorder include a low number of red blood cells (anemia), repeated infections, and periodic episodes of pain. The severity of symptoms varies from person to person. Some people have mild symptoms, while others are frequently hospitalized for more serious complications.
The signs and symptoms of sickle cell disease are caused by the sickling of red blood cells. When red blood cells sickle, they break down prematurely, which can lead to anemia. Anemia can cause shortness of breath, fatigue, and delayed growth and development in children. The rapid breakdown of red blood cells may also cause yellowing of the eyes and skin, which are signs of jaundice. Painful episodes can occur when sickled red blood cells, which are stiff and inflexible, get stuck in small blood vessels. These episodes deprive tissues and organs, such as the lungs, kidneys, spleen, and brain, of oxygen-rich blood and can lead to organ damage. A particularly serious complication of sickle cell disease is high blood pressure in the blood vessels that supply the lungs (pulmonary hypertension), which can lead to heart failure. Pulmonary hypertension occurs in about 10 percent of adults with sickle cell disease.
