Which of these statements best describes a similarity between respiration and diffusion?
Both absorb carbon from the atmosphere.
Both release carbon into the atmosphere.
Both increase the level of carbon in the biosphere.
Both increase the level of carbon in the geosphere.
Answer:
Both release carbon into the atmosphere.Explanation:
Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes- Internal respiration - this is the movement in the internal tissues between cells and capillaries, and - External respiration - when gas is exchanged between the alveoli and lung capillaries. Perfusion refers to the blood flow to tissues and organs. Alveoli are perfused by capillaries so the diffusion of oxygen and carbon dioxide can take place.
Answer: Both release carbon into the atmosphere.

Which of these is not a human cause of extinction of species?
Choose the correct answer.
A) Clearing of an area for farmland.
B) A dam built in a river for city water usage.
C) Competition for food resources with another native species.
D) The introduction of a new predatory species to an island by boat.
The statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.
What is species?Species may be characterized as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. The process of speciation is generally mediated through the species.
In the present time, the human causes of the extinction of species are majorly popular. It includes the clearance of an area for farmland and industrialization, the building of a dam for city water utilization, the introduction of a new predatory species to an island by boat, and many more.
But the process of competition for food resources with another native species is ultimately the behavior governed by the respective species itself without the interference of humans.
Therefore, the statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

6. Your friend is trying to gain some more muscle and has started lifting weights.
You read that muscle structure is primarily built by putting amino acids together through protein synthesis.
What foods should you recommend to your friend, so that they can increase the amount of amino acids in their diet?
1. Identify a food from the selection that they should eat.
2. Explain how you know that food has the macromolecule they need.
Answer:
He should start out doing little amount , any workout his wants but try to hold the weight for 1 min , making sure that he doesn't lift too fast instead he should do them slow and hold it for a while for he can feel the burn in his muscle and with time add the reps and hold it longer

In 2-3 sentences, explain how crossing over and independent assortment in sex cells affect the appearance of the fully developed organism.
Answer:
Explanation:
Crossing over and independent assortment in gametes (sex cells) can lead to genetic variation in the DNA of these gametes and lead to offspring looking different from their parents. Crossing over is the exchange of DNA between a pair of homologous chromsomes (the mom and the dad) which results in recombinant chromsomes that have new combinations of genes. Independent assortment refers to the lining up of chromsoomes along the metaphase plate in meiosis 1, and this can lead to different combinations of gametes.
How do environmental factors help determine which members of a species will survive or become extinct?
Answer:
Natural selection
Explanation:
Whether or not an organism survives to reproduce depends on their surrounding environment. This is natural selection. Over time, that mutation can develop into a distinguishable adaptation and/or become more pronounced in a species since it increases the chances of survival.

See Concept 22.3 (Page 475) it is broad enough in scope to explain many observations it is supported by a massive body of evidence from many disciplines it is general enough to provide many testable hypotheses All of the above are correct. None of the above is correct.
Answer:
All of the above are correct:
it is broad enough in scope to explain many observations it is supported by a massive body of evidence from many disciplines it is general enough to provide many testable hypothesesExplanation:
The scientific theory is a conceptual framework used to explain facts or phenomena and to make predictions.
The theory is fundamental to science because it allows scientists to organize and understand observations.
The construction of a theory begins with a hypothesis. The scientist believes that a phenomenon occurs in a certain way, so he/she performs observations under the scientific method to prove that his/her hypothesis is valid or not valid. The systematization of the observations and the empirical data collected might derive from a scientific theory that explains the analyzed phenomenon.
A scientific theory is a knowledge that has been contrasted in several ways.
The theory of evolution has been tested in too many ways and by different disciplines, becoming one of the most strong theories. Research areas such as biology, genetics, paleontology, and geology, among others, have been tasting it and explaining many facts from it, which makes it broad enough to base on it any explanation of life.

Explain the difference between DNA, chromosomes, genes, and the protein that is created.
I NEED THIS QUICKLY PLS!!!
Explanation:
DNA is a long molecule that contains our unique genetic code.DNA is composed of two strands that wrap around each other to form a double helix shape.
Genes are sections of DNA that contain the set of instructions to produce one specific molecule in your body, usually a protein. These proteins control how our body grows and works; they are also responsible for many of our characteristics, such as our eye colour, blood type or height.
Chromosomes are bundles of tightly coiled DNA located within the nucleus of almost every cell in our body. Humans have 46 chromosomes . We inherit one set of 23 chromosomes from our mother and one set of 23 chromosomes from our father. So we have two sets of 23 chromosomes or 23 pairs.

Cardiac output is the amount of blood pumped by the heart in one minute. Which of these will increase cardiac output?
Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.
The overriding problem with both theories of muscle growth, hypertrophy and hyperplasia, is that __________. A. neither can be accepted as correct because muscles growth is difficult to study in humans B. neither one is theoretically possible C. neither has been studied by reputable scientists D. neither has been accepted by member of the fitness community Please select the best answer from the choices provided.
Answer: A. neither can be accepted as correct because muscles growth is difficult to study in humans.
Explanation:
Hypertrophy can be defined as the increase in the fiber size of the muscle whereas the hyperplasia can be defined as the increase in the number of muscle fibers. Additionally the hypertrophy suggests that adding more proteins to the fibers is suggestive of the growth of the muscles. But these two theories cannot be directly related to the muscle growth in humans as the development and growth of muscles are dependent upon several factors like diet, any kind of disease which restrict the muscle growth and movement, physical activities, mineral availability responsible for growth, malnutrition, and others.
