How are birds adapted for flight? What are the uses for feathers?

Answers

Answer 1

Answer:

Instead of heavy jaws and teeth, they have lightweight beaks. And instead of fur, they have feathers. These are light, streamlined and cleverly adjustable for flight control. Their bones are also hollow making them lighter for flight

Reflect again on competitive relationships. What would happen if the factor became more abundant or unrestricted?

Answers

Answer:

If a factor became more abundant, there would still be competition, but there would be less. *See below for an explanation that makes a little more sense (No, I am not sending you a link)*

Explanation:

In every ecosystem, there is competition. The competition could be for mates, food, shelter... anything, really. However, when those resources become more prevalent, there still might be competition, but there would probably be less than before. Let's try an example: Imagine that we were about to endure an incredibly strong hurricane. If you have ever prepared for a hurricane, you would most likely understand that if you get to the stores too late, there most likely wouldn't be much to choose from. Everything would be cleared from the shelves. Now there is competition for resources such as food and water that we would need to spend several days without power and electricity. However, if the shelves were to restock and everything is replenished, there wouldn't need to be any fighting over toilet paper, right? The same happens with plants and animals. If there is a sudden abundance of resources, they no longer need to compete so aggressively. *You might also see an increase in population, too*

Sorry, I gave such a wordy answer. I just really, really, really want you to understand so you good grades. I hope you understand :) :) :)

If the factor became more abundant or unrestricted, the competition will definitely increase among the organisms in the ecosystem.

What is Competition?

Competition may be defined as a type of species interaction that significantly affects both species negatively because both species here compete for the same resources. It is a type of negative-negative interaction.

According to the context of this question, if a factor or resource remarkably increases its abundant and became unrestricted, it will definitely lead to the process that increases the competition between two or more species. This is because it allows the organisms to move away from their original niches.

Therefore, if the factor became more abundant or unrestricted, the competition will definitely increase among the organisms in the ecosystem.

What is the greenhouse effect?

Answers

Answer:

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases in a planet's atmosphere radiate energy in all directions.

Explanation:

the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.

SPACE! What is a main sequence star? What event causes a star to leave the main sequence?

Answers

Explanation:

The main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness.

a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence. Stars smaller than a quarter the mass of the sun collapse directly into white dwarfs. When stars run out of hydrogen, they begin to fuse helium in their cores. This is when they leave the main sequence. High-mass stars become red supergiants, and then evolve to become blue supergiants. It's fusing helium into carbon and oxygen.

Taproot is a root system where roots develop from a single nodule.these are usually deep rooted .thus the plant gets tightly anchored to the soil. Fiberous root is a system where first a single root develops and further roots develop from it.these are not deep rooted and the plant is not properly anchored to the soil

Taproot consists of the one, long main route, where is secondary, and route lights are visible. Even the primary route is very thick as compared to other roots (carrot, radish).

c
If air pollution is high, then lichen growth is high.

d
If air pollution is high, then lung disorder cases are high.

Answers

a. Air pollution must affect lichen growth.

This hypothesis suggests that there is a relationship between air pollution and lichen growth, and that changes in air pollution levels will have an effect on lichen growth. This hypothesis is testable by observing changes in lichen growth in areas with different levels of air pollution and by conducting experiments to measure the effects of air pollution on lichen growth

how can you explain what you know about the heavily muscled cows with what you have learned about mutations, patterns of inheritance, incomplete dominance, sexaul reproduction, selective breeding and transferring of genetic information?

Answers

Myostatin (GDF-8) is a member of the transforming growth factor β superfamily of secreted growth and differentiation factors that is essential for proper regulation of skeletal muscle mass in mice. Here we report the myostatin sequences of nine other vertebrate species and the identification of mutations in the coding sequence of bovine myostatin in two breeds of double-muscled cattle, Belgian Blue and Piedmontese, which are known to have an increase in muscle mass relative to conventional cattle. The Belgian Blue myostatin sequence contains an 11-nucleotide deletion in the third exon which causes a frameshift that eliminates virtually all of the mature, active region of the molecule. The Piedmontese myostatin sequence contains a missense mutation in exon 3, resulting in a substitution of tyrosine for an invariant cysteine in the mature region of the protein. The similarity in phenotypes of double-muscled cattle and myostatin null mice suggests that myostatin performs the same biological function in these two species and is a potentially useful target for genetic manipulation in other farm animals.

The transforming growth factor β superfamily encompasses a large group of secreted growth and differentiation factors that play important roles in regulating development and tissue homeostasis (1). We have recently described a member of this family, myostatin, that is expressed specifically in developing and adult skeletal muscle and functions as a negative regulator of skeletal muscle mass in mice (2). Myostatin null mice generated by gene targeting show a dramatic and widespread increase in skeletal muscle mass. Individual muscles in myostatin null mice weigh 2- to 3-fold more than those of wild-type mice, primarily due to an increased number of muscle fibers without a corresponding increase in the amount of fat. To pursue potential therapeutic and agricultural applications of increasing muscle mass by inhibition of myostatin activity, we have been characterizing myostatin in animals other than mice. Here we report that the myostatin gene is highly conserved among vertebrate species and that two breeds of cattle that are characterized by increased muscle mass (double muscling), Belgian Blue (3) and Piedmontese (4), have mutations in the myostatin coding sequence. These results demonstrate that the function of myostatin has been highly conserved among vertebrates. hope it helps
