Functions of the large intestine include Select one: A. most of the chemical breakdown of food. B. absorption of bile salts. C. secretion of vitamins. D. reabsorption of water and compaction of feces. E. production of gas to move waste toward the rectum.

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.

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.

Answer:

The correct answer is option A "Duplication".

Explanation:

Chromosomal duplication is defined as a type of rearrangement of genetic material at which extra copies of a DNA fragment are created. In this case if a broken chromosomal fragment becomes reattached, this fragment will represent an extra copy, and therefore the resultant genetic material is considered a chromosomal duplication.

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.

Answer:

Wilting occurs due to excess removal of water from plant body.

Crop rotation.

Explanation:

The main use of blue green algae is that it has the ability of fixing atmospheric nitrogen for the plants. Oil is extracted from Neem leaves which is used as fungicide and pesticide for plants. Turmeric is used as healing of wounds for both plants and animals. It also prevent fungal and bacterial disease in plants. Plants will wilt if not watered because water is removed from the body of plants in order to cool down the inner temperature so due to removal of excess water from plant body it will dry and start wilting. Crop rotation is used in these cropping system. Crop rotation is a practice of growing more than one crop on the same piece of land in a year.

Answer:

C. glycoproteins

Explanation:

Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.

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.

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.

When a volcano erupts, tiny particles from the geosphere are released into the air. So, the correct option is C.

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.

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]

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.

Rayleigh wave, surface acoustic waves called Rayleigh waves move along the surface of solids, hence option D is correct.

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.

Explanation:

A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.

Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.
