The process whereby the earth’s life changes over time through changes in genes of populations of organisms in succeeding generations is called____.a. emigration.b. mutation.c. natural selection.d. evolution.e. genetic drift.
Answer:
The correct answer is option : d. evolution.
Explanation:
Change in the heritable traits or characteristics of population of a organism over time by the adaption or changes in genes of such population over successive generation is known as the evolution.
These changes that cause the evolution of the biological population is caused by the process of adaption through natural selection that is the ability of the passing beneficial genes from parent to offspring.
Thus, the correct answer is option D. evolution.

Rayleigh wave, surface acoustic waves called Rayleigh waves move along the surface of solids, hence option D is correct.
What is seismic wave?They are commonly employed in non-destructive testing to find flaws and can be created in materials in a variety of methods, as by a localized impact or by piezoelectric transduction.
These include what are known as Rayleigh waves. A Rayleigh wave's amplitude decreases with depth below the surface and becomes noticeably tiny at depths greater than a few wavelengths.
As a result, the disturbance is limited to a solid's surface layers. The motion experienced by the surface layers includes both transverse and longitudinal components.
Therefore, Rayleigh wave type of seismic wave is highlighted in the image.

The town in this image is near an inactive volcano. If the volcano were to violently erupt, which location would be least affected by volcanic ash and lava?
Answer:
i think it is the state park im not sure but lmk if im wrong or right
Explanation:
The correct answer is the plane, as it is flying in the sky, but the lava from the volcano after its eruption can easily flow down to the park, hospitals, etc., and the plane is least about to be affected by the volcanic eruption.
What is a volcanic eruption?A volcanic eruption is a natural phenomenon that occurs when magma, ash, and gases are expelled from a volcanic vent or fissure in the Earth's surface. Volcanic eruptions can range from relatively small and quiet to explosive and violent, and they can have significant impacts on the environment and on human populations. Volcanic ash and lava can be carried by the wind over large distances, so the direction of the wind and its strength are important factors in determining which areas will be most affected. Areas that are located upwind from the volcano are likely to be more affected by volcanic ash and lava than areas that are located downwind.
Hence, the correct answer is the plane, as it is flying in the sky, but the lava from the volcano after its eruption can easily flow down to the park, hospitals, etc.

Find the weight of a pine tree that has a circumference of 14 inches and a height of 120 feet. Use the equation: W = b0 + b1(D2H)
Answer:
The answer is below
Explanation:
The weight of trees is calculated using the equation:
[tex]W=b_o+b_1(D^2H)[/tex]
W is the tree weight in tons, D is the diameter of the tree in inches, H is the height of the tree in feet and [tex]b_o \ and\ b_1[/tex] are constants.
The circumference is given by:
Circumference = 2πr
Where r is the radius and 2r is the diameter
Therefore:
14 = 2(22/7)× r
14 = (22/7)×2r
2r= 14 × 7 / 22
Diameter = 2r = 4.455 inches
[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381.643b_1\\Let\ us\ assume\ b_o = -35,b_1=1.9.\\Therefore\\W = -35+2381.643(1.9)\\W=4490 \ tons[/tex]

questions:
Should I or can I eat salty foods?
Do I have to check my pressure immediately?
Do I have to follow a balanced diet?
Is it good to do physical activity?
Do I have to worry about the signs of eye flickering and headache?
Explanation:
Blood pressure is regulated by endogenous mechanisms, although these sometimes fail and it is necessary to take drugs to reduce high blood pressure, an example of which is beta-blockers.
Blood pressure is also regulated by diets based on low sodium consumption, necessary calories and with great contributions of nutrients since cardiac or cardiovascular health is also essential in the face of possible formation of atheroma plaques.
The increase in blood pressure with the appearance of atheroma plaques is very common, and it is also the two most frequent causes of AMI (acute myocardial infarction)

2 Describe why it would be an advantage for the seeds to be able to grow at any angle
Answer:
Seed grow at any angle is good for the plant because the barrier did not stop the plant growth.
Explanation:
If we planted a seed in the soil and there is any barrier such as stone or brick etc inside the soil so the roots change its direction because the seed grows at any angle. The shoot that emerge from the seed grow in upward direction if the stem is strong but some plants also grow horizontally due to weak stem so it is not compulsory for the plant to grow in only one direction, it grows whatever they want.

20.
An amoeba divides in half.
21.
A bean plant produces seeds in long pods.
22.
Pollen grains are released from a flower.
23.
A sea star produces a new arm after losing one to a predator.
Answer:
New leaves appear on a tree in spring. - NO
An amoeba divides in half. - YES
A bean plant produces seeds in long pods. - YES
Pollen grains are released from a flower. - YES
A sea star produces a new arm after losing one to a predator. - NO
Explanation:
The appearance of new leaves has nothing to do with reproduction but rather regeneration.
An amoeba dividing in half is a form of reproduction known as asexual. Binary fission is a reproductive process in which an organism divides into two and each half develops into new independent organisms.
A bean plant producing seed is part of the reproductive process. After fertilization, the ovule of a flower becomes the seed. A seed in itself is a ripened fertilized ovule.
The release of pollen grains from the anther of a flower to the stigma of a compatible flower in the same or different individuals plants is known as pollination. Pollination is a reproductive process similar to fertilization.
A sea star producing a new arm after losing one to a predator is a regeneration process rather than a reproductive process.
The Peppered moth is white with black spots, which helps it blend in with the bark on beech trees. The burning of coal in Great Britain caused many beech trees to become black with soot. Over time, the Peppered moth became all black in order to blend in with the new bark color. What type of example is this? homeostasis metabolism organization adaptation
Answer:
adaptation
Explanation:
Adaptation in Biology refers to the process whereby an organism adjust to its natural environment in order to increase its chance of survival or in other words, the organism becomes better suited to its natural habitat by possession of some adaptive features.
In this example, a white peppered moth with black spots initially possess these color combination in order to blend to its natural environment, which is the bark on beech trees. However, due to the burning of coal in Great Britain which caused many of the beech trees to be black, the peppered moths had to ADAPT to this change in environmental color by becoming all black in order to blend in with the new bark color.
Therefore, this is an example of ADAPTATION.

When a volcano erupts, tiny particles from which of Earth's spheres are released into the air?
atmosphere
biosphere
geosphere
hydrosphere
When a volcano erupts, tiny particles from the geosphere are released into the air. So, the correct option is C.
What is Volcano?A volcano is a geological formation on the surface of the Earth that develops as magma and volcanic ash build up. During an eruption, lava, ash, and gas can escape through a crater or vent that is generally shaped like a mountain.
Explosive or non-explosive eruptions can have a large negative impact on the environment, causing ash fall, landslides, and lava flows, among other things. Tiny geosphere-derived particles are discharged into the atmosphere during volcanic eruptions.
All areas of volcanism contain compound volcanoes, but these volcanic structures are most common at plate convergence zones, where one tectonic plate plunges beneath another towards the earth's mantle.
Therefore, the correct option is C.

Rima eat guava explain how the teeth tongue and sliva will help to break it down
Answer:
Please find the role of teeth, tongue and saliva in digesting guava below
Explanation:
Digestion is generally the process of breaking down complex food substances into their simplest form. However, as easy as this sounds, there are series of processes that must take place in between to achieve the final result.
Once a food substance like guava enters the mouth (ingestion), it initially gets chewed by the TEETH in order to break it down to smaller masses that can be swallowed. During the process of chewing, the TONGUE helps to move the food around the mouth and later helps push it down the gullet/digestive tract. SALIVA, on the other hand, creates a moisturizing environment for the food to form a Bolus (round mass of food ready to pass down the esophagus). The saliva also contains an enzyme called AMYLASE that helps chemically degrade starch content of the food before passed through the digestive tract.
While performing an experiment, it is important to:
a. change the control setup
b. test many different variables at the same time
c. reach a conclusion
d. record observations and measurements
Answer:
D
Explanation:
While performing an experiment, it is important to record observations and measurements, as in Option d. Option d is correct regarding the facts of the experiments, while the others are wrong.
What is an experiment?The experiment is carried out to observe the hypothesis, and in this process, a control set-up is taken whose value or result is already known, and the variables are taken and compared with the control. The controls set should never change in the experiment because the variables are tested with reference to them, and the measurements and observations of the experiment should be taken into consideration to prove the hypothesis. All the variables should not be tested at once because if this is done, it would introduce error into the experiment, and not all the experiments are done to get the conclusion.
Hence, while performing an experiment, it is important to record observations and measurements, as in Option d.

During the process of translation in a eukaryote messenger RNA is spliced in the nucleus. amino acids are synthesized by RNA polymerase. transfer RNAs are joined together by a large enzyme complex. ribosomes must be imported into the nucleus. mRNA interacts with ribosomes in the cytoplasm.
Answer:
mRNA interacts with ribosomes in the cytoplasm.
Explanation:
The correct option would be that mRNA interacts with ribosomes in the cytoplasm.
Translation involves the use of genetic codes in mRNA to synthesize amino acids that are eventually linked together by polypeptide bonds to form proteins.
During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon.
Hence, the correct answer out of all the options is that mRNA interacts with ribosomes in the cytoplasm.

how do i explain this?
Answer:
Oxygen debt is a physiological phenomenon in which a person consume oxygen at fater rate that it replaced by new oxygen molecules.
As shown in the graph, oxygen debt occurs just after the end of exercise because oxygen is consumed at faster rate during exercise that leads to increased respiration and body attempts to replace the used oxygen.
To overcome the problem of oxygen debt, a person should take rest that allows the body to replenish its oxygen supply.
