As a frog develops from a tadpole into an adult frog, it goes through changes that are signaled by hormones within the body. Which best describes the role hormones play in changing a tadpole to a frog?
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.

This picture shows a cross-section of a blood vessel. The diameter of the
lumen in Figure 10 is 25.0 mm. What is the actual diameter of the lumen of
this blood vessel?
lumen
magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
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.
In order to extract DNA from strawberry cells, what will need to happen at the cellular level?
Answer:
Tiene que romperse la membrana plasmática para poder acceder al núcleo de la célula y posteriormente romperse también la membrana nuclear para dejar libre al ADN
Explanation:
While looking at a cell under a microscope, a scientist is able to see a biological molecule. This molecule is a nuclei acid with double strands and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on the information, what conclusion can the scientist draw regarding this nuclei acid?
A. the nuclei acid is DNA and would be found in the cytoplasm.
B. the nuclei acid is DNA and would be found in the cells membrane.
Describe what happens to water particles when ice metls.
Answer:Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water. In the melting process, the water molecules actually absorb energy.

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

A. Lines that show the shape of a
magnetic field
B. Lines that show the path of electrons
C. Lines that show aligned atoms
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.
You are comparing the density of sea water to the density of fresh water. (Remember,
density is mass divided by volume.) Describe how you could determine the density of
sea water, including the names of the equipment needed to make the required
measurements.
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.
Im not sure if anyone knows this or not.

3. Which is an example of genetic biodiversity?
a. Different skin color within a species
b. Different types of species in an ecosystem
C. Every organism has the same genetic sequence
d. All populations look identical within a species
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.
What is genetic biodiversity?
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.
