Can someone please help me??



Which type of reproduction is responsible for genetic variation?

Answer:

when you look a streetlight from far it will be some how not bright. the other stars are far from planet earth . but the  sun is near

Explanation:

Solar energy

Explanation:

Large-scale surface ocean currents are driven by global wind systems that are fueled by energy of the sun. :)

The practice of removing natural vegetation and replacing it with concrete and structures is known as urbanization. This is the correct answer to fill in the blank.

Industrialization, commercialization, rural-urban migration, lifestyle changes, career opportunities, social advantages, etc. are the primary reasons of urbanization. The process of urbanization is when people move from rural to urban areas for a variety of reasons.

Urban areas can expand due to a rise in the population or because people move there. Urbanization frequently causes habitat loss, deforestation, and freshwater extraction from the environment, which can reduce biodiversity and change species ranges and interactions.

Answer:

Blue Eyes Are: Recessive

Explanation:

The brown eye form of the eye colour gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. I hope this helps :) Good luck on your assignment!!!

I'm pretty sure the answer to 1 is A, but I know for a fact that soil contains microorganisms and microbes.

Answer:

C

Explanation:

b/c the nucleus of the cell contains the information needed to build a whole new animal, plant, bacterium or fungus.

Answer:

Antibiotics are not effective for new strains and so new resistant pathogens survive and reproduce, which leads to the increasing population of resistant pathogens and spread rapidly.

Bacteria can evolve and adapt themselves quickly as they are able to reproduce at a fast rate. Mutations of bacteria produce new strains that are resistant to certain antibiotics, such as penicillin, and cannot be destroyed by the antibiotic so they spread more rapidly.

Answer:

i think it would be c

Explanation:

Answer:

Somatic mutations are mutations that occur in body cells, that is the cells that do not make gametes. These mutations are not passed on to further generations; for example, if a mutation that changes a gene in a skin cell would not affect your children because skin cells don't produce gametes.

Answer: dominant

Explanation:

Answer:

Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.

Answer:

The water will move quickly

Explanation:

Answer:

The pre-mRNA molecules undergo three main modifications. These modifications are 5' capping 3' polyadenylation and RNA splicing which occur in the nucleus before RNA is translated.

Explanation:

mRNA compares to the hereditary succession of quality, and is perused by a ribosome during the time spent combining a protein.

it should go through extra handling before it leaves the core. This might incorporate joining, altering, and polyadenylation. These cycles adjust the mRNA in different ways. Such alterations permit a solitary quality to be utilized to make more than one protein. Exons are segments of mRNA which become "communicated" or converted into a protein. They are the coding bits of a mRNA atom.

Explanation:

Answer:  The heart muscle of conditioned athletes enlarges and strengthens.

Increased cardiovascular fitness causes real physical changes in the structure of the heart. The muscles in the heart wall thicken, and the heart pumps more blood with each beat. That increased efficiency means an athlete's resting heart rate falls to a level that could indicate trouble in a nonathlete. Many athletes don't realize that high levels of conditioning also cause heart symptoms that doctors might mistake for serious problems.

Answer:

1. Chloroplast

2. Photosynthesis

3. 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

4. Sunlight

5. Glucose

6. Oxygen

7. Carbon Dioxide

8. Water

9. Energy

10. Mitochondrion

11. Cellular Respiration

12. C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

Answer:

1. Chloroplast

2.photosynthesis

3. 6 CO₂ (carbon dioxide) +12 H₂O (water) + light -->C6H12O6 (glucose/sugar) +6 O₂ (carbon dioxide) + 6 H₂O (water)

4. Light

5 and 6) Glucose (C₆H₁₂O₆) and O₂

7 and 8) CO₂ and Water (H₂O)

9) energy (ATP)

10) Mitochondria

11) Cellular respiration

12) I think you need the equation as well:

Explanation: C₆H₁₂O₆ (glucose) + 6O₂ (oxygen) --> 6CO₂ (Carbon Dioxide) + 6 H₂O (water) + ATP (energy)

1. Chloroplasts have thylokoids or stacked membranes like it has.

2. Photosynthesis is the process of converting light into usable energy.

3. That is the equation of photosynthesis. Their are different ways of writing this for example: 6 CO₂ + 6H₂O + light -->C₆H₁₂O₆ + 6 O₂ which is balancing the water. Check to see what your teacher used in the book/notes.

4. Light is required for photosynthesis and the sun is providing it.

5 and 6) The mitochondria uses both of these in its processes that were first made in photosynthesis.

7 and 8) Both are created by mitochondria and are used in chloroplasts.

9) Energy is produced in the mitochondria with help from the Chloroplast.

10) It is usually depicted with those lines in it.

11) That is the process's name.

12) This is the equation of cellular respiration.

Answer:

1. Lactose, H2O, and lactase.

2. Galactose and glucose.

3. You converted lactose, H2O, and lactase into galactose and glucose.

I don't know about the last one so I would do that one yourself because we can't see what the reaction was from.

Answer:

The answers is B

Explanation:

I just took a test that had this question on it.

B. contact with an infected person

Transmission occurs when an infected person interacts or exchanges bodily fluids with another person.  This can happen before the infected individual even realizes they are sick.

After a weekend field trip to the aquarium with their classmates, five pupils catch a cold. Because they may have come into contact with an infectious person, students became ill. Students became sick as a result of B. contact with an infected person

Answer:

Reflex action/reflex arc/reflex (allow "involuntary") The stimulus (heat) is detected by temperature receptors in the skin. This causes impulses to travel along a sensory neurone to the spinal cord, due to chemical changes across the synapses. Here they go along a relay neurone, and then are sent via a motor neurone to the effector (an arm muscle in this case). The muscle contracts, moving the hand away and preventing further harm.

Answer:

Your body uses water in all its cells, organs, and tissues to help regulate temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it's important to rehydrate by drinking fluids and eating foods that contain water.

Answer:

Water is needed for your digestive track as it digests foods. As water is also needed for each cell to properly function in your body.
