Answer:

B. 3.12 x [tex]10^{-3}[/tex] m

Explanation:

From the given picture, it can be deduced that;

the diameter of the image of lumen = 25.0 mm

                                                      = 25.0 ÷ 1000

                                                      = 0.025 m

And,

magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]

But magnification = 8,and diameter of the image of lumen = 0.025 m.

So that;

8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]

⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]

                         = 0.003125

Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

Earthquake proof buildings are those which have the ability to stand during an earthquake. Shock absorbers that is present between the building and the ground motion, able the building to remain upright during an earthquake. The shock absorbers has the ability to absorb all the disturbance produced in the building and for that purpose the building is safe.

Explanation:

Answer: In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence In  (frogs and toads), the metamorphic changes are more dramatic, and almost every organ is subject to modification Regressive changes include the loss of the tadpole's teeth and internal gills, as well as the destruction of the tail. At the same time, constructive processes such as limb development  are also evident. The means of locomotion changes as the paddle tail recedes while the hind limbs and forelimbs develop. The tadpole's cartilaginous skull is replaced by the predominantly bony skull of the frog. The teeth used for tearing pond plants disappear as the mouth and jaw take a new shape, and the tongue muscle develops. Meanwhile, the large intestine characteristic of herbivores shortens to suit the more carnivorous diet of the adult frog. The gills regress, and the gill arches degenerate. The lungs enlarge, and muscles and cartilage develop for pumping air in and out of the lungs. The sensory apparatus changes, too, as the lateral line system of the tadpole degenerates, and the eye and ear undergo further differentiation The middle ear develops, as does the tympanic membrane characteristic of frog and toad outer ears. In the eye, both ingratiating membranes and eyelids emerge.

Answer:

A

Explanation:

Has to be the same family to be genetic and you have to find which has the most variety

Different skin color within a species is an example of genetic biodiversity. Therefore, option (A) is correct.

Genetic biodiversity refers to the variety of genes and genetic traits that exist within a population or species. It is a fundamental aspect of biodiversity, as it underpins the ability of species to adapt to changing environmental conditions and to maintain resilience in the face of threats such as disease, climate change, and habitat loss.

Genetic biodiversity arises from mutations, genetic recombination, and other processes that generate new genetic variation within populations. This diversity provides the raw material for natural selection to act upon, allowing organisms with advantageous traits to survive and reproduce.

Genetic biodiversity is important for ecosystem functioning and for the conservation of species, as it helps to ensure that populations are able to adapt to changing conditions and maintain their long-term viability. The loss of genetic biodiversity can have significant negative impacts on populations and ecosystems, making it an important focus of conservation efforts.

Answer:

C. They have trouble moving materials in and waste products out

Answer:

A

Explanation:

Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. The density of the lines indicates the magnitude of the field.

Answer:

To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.

First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.

Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.

I believe it's DNA, or deoxyribonucleic acid.

Answer:

Pulmonary blood vessel

Explanation:

The pulmonary blood vessel carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.

More specifically, the pulmonary artery carries low-oxygen blood to the lung from the right ventricle of the heart. The blood becomes oxygenated in the lung and the oxygen-rich blood is taken back to the left atrium of the heart by the pulmonary vein.
