A male cardinal’s red color is an example of a trait affected by natural selection. The females of the species choose mates base

d on the vibrant colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
increased variation in the shades of red because there is no advantage in one specific color
increased variation in the shades of red because the cardinals try different ways to impress the females
decreased variation in the shades of red over time because no form of the trait is advantageous
decreased variation in the shades of red after a single generation

The recommended daily amount of protein for a woman is 45g How many grams of cheese would provide 45g of protein
yulyashka [42]

Answer:

200 g of cheese

Explanation:

From the table attached, we can see that each 100 g of cheese contain 22.5 g of protein. For us to calculate the amount of cheese needed to provide about 45 g of protein, we use the formula:

Amount of cheese for 45 g of protein = (100 g of cheese/ 22.5 g of protein) * 45 g of protein

Amount of cheese for 45 g of protein = 200 g of cheese

Therefore 200 g of cheese would be needed to provide 45 g of protein.

All materials within ecosystems can be recycled.
netineya [11]

Answer:

All the things expect enegry are recycled.

Explanation:

  • When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled.
  • The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.

But incase of enegry it cannot be recycled but frequently transfered from one form to another form.

Do some cows some (acquire/inherit) traits that make them have more muscles compared to other cows.
just olya [345]

Answer:

Explanation:

Molecular biology has enabled the identification of the mechanisms whereby inactive myostatin increases skeletal muscle growth in double-muscled (DM) animals. Myostatin is a secreted growth differentiation factor belonging to the transforming growth factor-β superfamily. Mutations make the myostatin gene inactive, resulting in muscle hypertrophy. The relationship between the different characteristics of DM cattle are defined with possible consequences for livestock husbandry. The extremely high carcass yield of DM animals coincides with a reduction in the size of most vital organs. As a consequence, DM animals may be more susceptible to respiratory disease, urolithiasis, lameness, nutritional stress, heat stress and dystocia, resulting in a lower robustness. Their feed intake capacity is reduced, necessitating a diet with a greater nutrient density. The modified myofiber type is responsible for a lower capillary density, and it induces a more glycolytic metabolism. There are associated changes for the living animal and post-mortem metabolism alterations, requiring appropriate slaughter conditions to maintain a high meat quality. Intramuscular fat content is low, and it is characterized by more unsaturated fatty acids, providing healthier meat for the consumer. It may not always be easy to find a balance between the different disciplines underlying the livestock husbandry of DM animals to realize a good performance and health and meat quality.
