In the example about the beaver's teeth, is it possible for just one beaver to evolve and get a favorable trait in its lifetime.

A. Yes because it makes sense it would need better teeth to cut down the tree

B. No because all traits are inherited and better teeth would have to come from those beavers with a trait for better teeth

C. Yes because animals control their traits.

how does climate and vegetation vary with latitude and elevation?​

Answers

Answer:

Climate and vegetation vary with latitude and altitude of an area. Latitude measures distance from the equator; altitude measures elevation above sea level. ... Deserts have little precipitation and little vegetation. They are found in tropical, temperate, and Polar Regions.

The climate and vegetation may significantly vary with the latitude and elevation. This is because as elevation increases the temperature decreases gradually that do not favor the actual growth of vegetation.

What is Climate?

Climate may be defined as a type of weather conditions that are persuading in any geographical location for a long period of time. In a more simple sense, it is characterized as the long-term pattern of weather in a particular area.

Latitude estimates the distance from the equator part of the earth and goes through the tropical, temperate, and colder regions of the earth. The vegetation is typically reduced with increasing the altitude or elevation with respect to the sea level.

It may also be noticed that the vegetation may alter with respect to the geographical location of the whole earth. It was never found to be completely absent.

Therefore, the climate and vegetation may significantly vary with the latitude and elevation.

What is the role of photosynthesis and cellular respiration in the cycling of carbon; include the biosphere, atmosphere hydrosphere and geosphere?

Answers

Photosynthesis and cellular respiration are important components of the carbon cycle, in which carbon is exchanged among the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes.
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Answers

Answer:

Lactic acid accumulation in the leg muscles

Explanation:

Muscle cramps are painful feelings caused by sudden contractions of the muscle. Cramps are caused by several reasons, however, based on the description of Akashay's activity, it is caused by ACCUMULATION OF LACTIC ACID in the leg muscles due to strenuous exercise.

According to this question, Akashay decided to run a marathon without any prior training. However, he started to get cramps on his thigh coupled with rapid breathing. There is a lack of oxygen in his cells, hence, anaerobic respiration was used leading to the formation of lactic acid. The buildup of lactic acid is what causes the painful sensation called CRAMP.

how sexual reproduction plays its role in avoiding genetic monotomy

Answers

Answer:

Abstract

The relative contributions of sexual and asexual reproduction to the genetic structure of populations can be difficult to determine for fungi that use a mixture of both types of propagation. Nuclear RFLPs and DNA fingerprints were used to make indirect and direct measures of departures from random mating in a population of the plant pathogenic fungus Mycosphaerella graminicola during the course of an epidemic cycle. DNA fingerprints resolved 617 different genotypes among 673 isolates sampled from a single field over a 3-month period. Only 7% of the isolates represented asexual clones that were found more than once in the sample. The most common clone was found four times. Genotypic diversity averaged 85% of its maximum possible value during the course of the epidemic. Analyses of multilocus structure showed that allelic distributions among RFLP loci were independent. Pairwise comparisons between individual RFLP loci showed that the majority of alleles at these loci were in gametic equilibrium. Though this fungus has the capacity for a significant level of asexual reproduction, each analysis suggested that M. graminicola populations maintain a genetic structure more consistent with random-mating over the course of an epidemic cycle.

With your partner, decide on a plan for investigating the effect of exercise on heart rate. The exercise could be running in place or doing jumping jacks. Record the steps below.



Pls I need the answer fast

Answers

Answer:

Materials

• Scrap piece of paper

• Pen or pencil

• Clock or timer that shows seconds or a helper with a watch

• Comfortable exercise clothes (optional)

• Calculator

Preparation

• Practice finding your pulse. Use the first two fingers of one hand to feel your radial pulse on the opposite wrist. You should find your radial pulse on the "thumb side" of your wrist, just below the base of your hand. Practice finding your pulse until you can do it quickly. (You can alternatively take your carotid pulse to do this activity, but be sure you know how to safely take it and press on your neck only very lightly with your fingers.)

• Measure your resting heart rate, which is your heart rate when you are awake but relaxed, such as when you have been lying still for several minutes. To do this, take your pulse when you have been resting and multiply the number of beats you count in 10 seconds by six. This will give you your resting heart rate in beats per minute (bpm). What is your resting heart rate? Write it on a scrap piece of paper.

• You will be measuring your heart rate during different types of physical exercises over a period of 15 minutes. Choose at least two different exercises. Some examples include jumping rope, lifting a two-pound weight, riding a bike, hula-hooping, walking, etc. Gather any needed materials. (If you want to make a homemade hula-hoop, steps for doing this are given in the activity Swiveling Science: Applying Physics to Hula-Hooping .) Do you think the activities will affect your heart rate differently? How do you think doing each activity will affect your heart rate?

Procedure

• Choose which exercise you want to do first. Before starting it, make sure you have been resting for a few minutes so that your heart is at its resting heart rate.  

• Perform the first exercise for 15 minutes. While you do this, write down the number of beats you count in 10 seconds after one, two, five, 10 and 15 minutes of activity. (You want to quickly check your pulse because it can start to slow within 15 seconds of stopping exercising.) How do the number of beats you count change over time? How did you feel by the end of the exercise?

• Calculate your heart rate after one, two, five, 10 and 15 minutes of exercise by multiplying the number of beats you counted (in 10 seconds) by six. How did your heart rate (in bpm) change over time?

• Repeat this process for at least one other exercise. Leave enough time between the exercises so that your heart rate returns to around its normal resting level (this should only take a few minutes). How did you feel by the end of the second exercise? How did your heart rate change over time for this exercise?  

• Take a look at the results you wrote down for this activity. Which exercise increased your heart rate the most? Which exercise increased your heart rate the fastest? Which exercise(s) elevated your heart rate to the target heart rate zone (50 to 85 percent of your maximum heart rate, where your maximum heart rate is 220 bpm minus your age)? Do you notice any consistent patterns in your results?

• Extra: Try this activity again but test different physical exercises. How does your heart rate change when you do other exercises? How are the changes similar and how are they different?

• Extra: Measure your heart rate while lying down, while sitting down, and while standing. How does your heart rate change with body position?  

• Extra: Repeat this activity with other healthy volunteers. How does their heart rate compare to yours? How does their change in heart rate while exercising compare to how yours changed?  

• Extra: Try this activity again but vary the intensity of your exercise. What intensity level elevates your heart rate to 50 percent of its maximum heart rate? What about nearly 85 percent of its maximum? Be sure not to exceed your recommended target heart rate zone while exercising

Explanation:

If you did a moderately intense exercise, such as walking, you may have seen an initial jump in your heart rate (where your heart rate falls within the lower end of your target heart rate zone within about one minute of exercise), but then your heart rate only slowly increased after that. After 15 minutes, you may have reached the middle of your target heart rate zone. To reach the upper end, people usually need to do a moderately intense exercise for a longer amount of time (such as for 30 minutes). If you did a more strenuous exercise—hula-hooping, for example—you may have seen a higher initial bump in your heart rate (such as reaching the middle of your target heart rate zone after just one minute of exercise), and then your heart rate stayed about the same for the remaining 14 minutes of exercise. Overall doing a more strenuous exercise generally raises a person's heart rate faster compared to doing an exercise that is only moderately i

Answer:

Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.

Explanation:

It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.

Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".

A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.
