Where sexual selection is based on male competitiveness, bright-colored males are expected to be seen.
What distinguishes sexual selection?Sexual selection theory holds that the emergence of some noticeable physical qualities in animals, such as pronounced colour, increased size, or spectacular adornments, may provide the possessors of these traits more success in attracting mates.
Because the number of gene copies in the next generation is also dependent on relative mating success, the strength of sexual selection is proportional to the relative increase in the number of offspring surviving to reproduce (Sn) and the relative number of mates a male with that character obtains.

In your own words, explain what the summary equation tells you about cellular respiration.
The summary equation for cellular respiration represents the conversion of glucose and oxygen into carbon dioxide, water, and ATP, the opposite process of photosynthesis. It indicates how cells extract energy from food and helps maintain stable atmospheric levels of oxygen and carbon dioxide.
Explanation:The summary equation for cellular respiration provides a concise description of the process by which cells convert glucose and oxygen into carbon dioxide, water, and chemical energy in the form of ATP (adenosine triphosphate). Specifically, the equation C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP represents the transformation of the energy contained in the bonds of glucose molecules into a form usable by cells for biological functions. This process is vital for the maintenance of life and is the mirror opposite of photosynthesis, where plants produce glucose and oxygen from carbon dioxide and water using energy from sunlight.
The exchange of carbon dioxide and oxygen through cellular respiration and photosynthesis worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and the electron transport chain. Each stage involves a series of biochemical reactions that progressively capture energy from glucose and transfer it into the high-energy phosphate bonds of ATP.

Over the decades local and global ice ages have lowered sea levels. As a result, there is often a decline in marine diversity due to - factors like salinity and temperature of water.
Salinity is the measure of the amount of salt present in any ocean or sea water. High salinity makes it impossible for marine life to survive. Similarly, the temperature of water should be maintained according to every organism's need. Like- Deep sea has a low temperature as compared to shallow sea, due to sunlight. So, deep sea creatures cannot survive in shallow water temperature and shallow water creatures cannot survive in deep sea.

Which structure do both nonvascular plants and seedless vascular plants have in common?
seeds
stems
spores
Spores are the structure which are present in both nonvascular plants and seedless vascular plants in common. Thus, the correct option is C.
What are vascular plants?Vascular plants are also called tracheophytes. These plants form a large group of land plants which have lignified tissues for the conduction of water and minerals throughout the plant and a specialized non-lignified tissue for the conduction of products of photosynthesis.
The seedless vascular plants contain vascular tissue but do not produce flowers or seeds. In seedless vascular plants, like ferns and horsetails, they reproduce through haploid, unicellular spores instead of seeds.
Non-vascular plants do not have any vascular tissues. Non-vascular plants do not possess roots, stems, or leaves which were present in the vascular plants.
Therefore, the correct option is C.

The human population has exceeded 7.06 billion with the developing countries accounting for 97% of the growth. What factor does not account for population growth in these countries ? A.) High fertility rates B.) Lower levels of education C.) Limited use of family planning D.) Improving economic opportunities
Answer is D.
There are many reasons for the rapid population growth rate in most developing countries is higher than in developed countries. Some of the major ones are: Women are least educated and they don't have easy access to birth control measures. Developing countries depend on agriculture and other farming activities. Children can be put to work at a young age to do these jobs. So, to improve economic condition of their families. Therefore, high fertility rate may not account to high population growth rate in most developing countries.

a punnett square shows the probability that the parents off spring will have a certain phenotype be cross the parents two genotypes
further Explanation:
so a punnett square take two parents and crosses them to calculate the chance you will get a certain phenotype by drawing a square and splitting it into four quarter you take the dads two genotypes and put them on the top of the square and you put the moms on the side now that you have the parents genotypes labeled you cross them the letters are there alleles so if you have a upper case allele then it is dominant meaning the offspring get the dominant trait (phenotype) now if you have two lower case letters then the offspring get the non-dominant trait (phenotype) so Bb is gets a dominant trait BB is a dominant trait but bb is a non dominant trait the way you cross them is say you have BBxbb here's what the chart will look like

These suns energy comes from the process of nuclear fusion in which hydrogen atoms form
Answer: Helium atoms
Explanation: The reaction taking place at the Sun is nuclear fusion reaction. It is a process where two or more atoms combine leading to formation of a new atoms. But here total mass of the reactants is not equal to total mass of the products. Some of the mass is lost as energy and this energy is produced in very enormous amount. At the Sun, four H atoms combine and form helium atoms. Along with this large amount of energy is produced which is responsible for huge amount of heat at the Sun.

you are looking through a microscope at some cells.each of the cells have a different structure. what can you infer about the cells
When viewing cells through a microscope and noticing that each cell has a different structure, it can be inferred that these cells have different functions or come from different types of organisms or tissues. The variation in cell structure is typically linked to the specific roles each cell performs, as a cell's structure is tailored to its function in accordance to the principle known as 'form follows function' in biology.
Cells are the basic structural and functional units of life, and their structures are intimately linked with their functions. The concept of 'form follows function' suggests that the structure of a biological entity will be shaped by the particular functions it performs. If the cells observed are structurally distinct, it implies that they were designed to carry out different tasks or come from various environments. For example, a neuron in the nervous system has a very different structure compared to a red blood cell, reflecting their unique roles in the body. Similarly, plant cells differ from animal cells in key structural components like cell walls and chloroplasts, which are related to their functions in photosynthesis and maintaining rigidity. Noticing different structures under the microscope implies that there is a diversity of cell types and possibly a range of biological functions being observed.
